Pls help! How do i Graph 4y = -3x - 8. explain the steps
Answer:
Step-by-step explanation:
to make a graph, when you have the equations, as you do, just make up a table of some x coordinates, you get to choose which ever ones you want so pick some easy ones, like - 2,-1 , 0, 1, 2 .. then put each of those numbers into your equations as the x ... one at a time, ofc, and see what you get out for y. then you have the y coordinate of your table
when you have your table then you can plot each of the points, if you use the Demos web site graphing tool you can make the graph on your computer , or use a graph paper.

A translation that maps the blue triangle onto the red triangle is :
Answer:
a translation of 5 units to the right followed of a translation of 2 units up.
Step-by-step explanation:
This seems to be a translation because if we measure the base of both triangles, we can see that the base of the blue triangle is 5 units long, and the base of the red triangle is also 5 units long.
To find the translation in this case, is easier to only analyze one point, so let's call A as the top vertex in the blue triangle and A' as the top vertex in the red triangle.
Here we only need to see the change between A and A'
So first, let's find the coordinates of both points.
The top vertex of the blue triangle is A (-3, 5)
The top vertex of the red triangle is A' (2, 7)
Now we need to find the difference between these points, this is the direct subtraction:
A' - A
(2, 7) - (-3, 5) = (2 - (-3), 7 - 5) = (5, 2)
So we get this, (5, 2)
This means that the translation is a motion of 5 units in the x-axis (because the number is positive, this means that the motion is in the positive x-axis)
And a translation of 2 units up.
Then the translation that maps the blue triangle into the red triangle is:
a translation of 5 units to the right followed of a translation of 2 units up.

a shelter had 4 spaniel puppies and 6 beagle puppies. Jack adopted 1/2 of the spaniel puppies, and carmen adopted 1/2 of the beagle puppies. who adopted more puppies? How do you know?
Answer:
If Jack adopted half of the spaniel puppies, and there are 4 spaniel puppies, that means that he adopted 2 puppies.
If Carmen adopted half of the beagle puppies, and there are 6 beagle puppies, then Carmen adopted 3 puppies. This means that Carmen adopted more puppies than Jack.
Step-by-step explanation:
1/2 of 4 = 2
1/2 of 6 = 3
Carmen adopted more puppies that is 3 and Jack adopted 2 puppies.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, a shelter had 4 spaniel puppies and 6 beagle puppies.
Jack adopted 1/2 of the spaniel puppies.
That is, 1/2 ×4 =2
Carmen adopted 1/2 of the beagle puppies.
That is, 1/2 ×6 =3
Therefore, Carmen adopted more puppies that is 3 and Jack adopted 2 puppies.

The price of an item has been reduced by 40%. The original price was $35. What is the price of the item now?
Answer:
$21 is the correct answer
Answer:
Step-by-step explanation:
First we have to find 1 percent of 35, and then we will multiply it by 40. So: 35/100 = 0.35
0.35 (40) = 14
35 - 14 = 21
So, the discounted price is now $21.
Find the seventh term of the
geometric sequence, given the
first term and common ratio.
a_=1 and r=-2/3
[?]
Answer:
[tex]T_7 = \frac{64}{729}[/tex]
Step-by-step explanation:
Given
[tex]a =1[/tex]
[tex]r = \frac{2}{3}[/tex]
Required
Determine the 7th term
The nth term of a gp is:
[tex]T_n = a * r^{n-1[/tex]
So, we have:
[tex]T_7 = 1 * \frac{2}{3}^{7-1[/tex]
[tex]T_7 = 1 * \frac{2}{3}^{6[/tex]
[tex]T_7 = 1 * \frac{2^6}{3^6}[/tex]
[tex]T_7 = 1 * \frac{64}{729}[/tex]
[tex]T_7 = \frac{64}{729}[/tex]
Without multiplying the numbers in each box, explain which box has the
greater value
Box A
Box B
Answer: A
Step-by-step explanation:
Box A has a greater value than Box B. Expression of box A on being solved will result in a bigger value than that of box B.
Expression, in mathematics, is a combination of numbers, variables, functions, etc in a meaningful way.
Without multiplying, it is needed to compare both expressions.
As in the operation 'multiplication', numbers can interchange their position around the symbol '×', so, changing places of 4 and 8 in the numerator of the expression of box A,
Box A: [tex]\dfrac{8}{5} \times \dfrac{4}{9}[/tex].
The first fractions in both expressions are the same now in both boxes, so the expression having a bigger second expression will have the greater value.
To compare the second terms of both expressions, make the denominator equal:
Box A: [tex]\dfrac{8}{9} = \dfrac{8}{9} \times\dfrac{2}{2} = \dfrac{16}{18}[/tex]
Box B: [tex]\dfrac{1}{2} =\dfrac{1}{2} \times \dfrac{9}{9} = \dfrac{9}{18}[/tex]
Since, [tex]\dfrac{16}{18}\geq \dfrac{9}{18}[/tex] as [tex]16 \geq 9[/tex],
Therefore, the expression in Box A is greater than that of Box B.

joesph is 14 years younger than twice joesephens age. Joseph is 32 years old. how old is josephene?
Step-by-step explanation:
Joesphene is 23 years old, because: 2x=32+14=>2x=46=>x=23 .
Answer:
Josephene is 23 years old
Step-by-step explanation:
First, you can assign the variables x and y to Joseph and Josephene, next you should write an equation. Since Joseph is 14 years younger than twice Josephene's age, you can write the equation x + 14 = 2y, if 32 is substituted in for x and the equation is simplified, you will end up with Josephene's age, 23.

In a certain city district, the need for money to buy drugs is stated as the reason for 75% of all thefts. Find the probability that among the next 5 theft cases reported in this district, (a) exactly 2 resulted from the need for money to buy drugs; (b) at most 3 resulted from the need for money to buy drugs.
Answer:
a) 0.0879 = 8.79% probability that among the next 5 theft cases reported in this district, exactly 2 resulted from the need for money to buy drugs.
b) 0.3672 = 36.72% probability that among the next 5 theft cases reported in this district, at most 3 resulted from the need for money to buy drugs.
Step-by-step explanation:
For each theft, there are only two possible outcomes. Either it was motivated by a need to buy drugs, or it wasnt. Thefts are independent, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
In a certain city district, the need for money to buy drugs is stated as the reason for 75% of all thefts.
This means that [tex]p = 0.75[/tex]
Next 5 theft cases
This means that [tex]n = 5[/tex]
(a) exactly 2 resulted from the need for money to buy drugs;
This is P(X = 2).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{5,2}.(0.75)^{2}.(0.25)^{3} = 0.0879[/tex]
0.0879 = 8.79% probability that among the next 5 theft cases reported in this district, exactly 2 resulted from the need for money to buy drugs.
(b) at most 3 resulted from the need for money to buy drugs.
This is
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{5,0}.(0.75)^{0}.(0.25)^{5} = 0.0010[/tex]
[tex]P(X = 1) = C_{5,1}.(0.75)^{1}.(0.25)^{4} = 0.0146[/tex]
[tex]P(X = 2) = C_{5,2}.(0.75)^{2}.(0.25)^{3} = 0.0879[/tex]
[tex]P(X = 3) = C_{5,3}.(0.75)^{3}.(0.25)^{2} = 0.2637[/tex]
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0010 + 0.0146 + 0.0879 + 0.2637 = 0.3672[/tex]
0.3672 = 36.72% probability that among the next 5 theft cases reported in this district, at most 3 resulted from the need for money to buy drugs.
Where are white blue and red boat in the Marina three fourths of the boats in the Marina are white for seventh of the remaining boats are blueAnd the rest are red if there are nine boats how many boats are in the Marina?
Answer:
28
Step-by-step explanation:
Here is the complete question used in answering this question :
Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?
We first have to determine the fraction of the boats that are red
1 - ([tex]\frac{3}{4}[/tex] + [tex]\frac{4}{7}[/tex])
1 - [tex]\frac{21 + 16}{28}[/tex]
1 - [tex]\frac{37}{28}[/tex]
1 - 1[tex]\frac{9}{28}[/tex]
= 9/28
so, 9/28 of the boats are red
let b represent the total number of boats
9/28 x b = 9
to find b, divide both sides of the equation by 28/9
b = 28
