Answer:
-4/3
Step-by-step explanation:
Answer:
m = - 4 /3
Step-by-step explanation:
Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m = y2 - y1 / x2 - x1
m =( -6) - (-2)/ 5 - 2
m = -6 plus 2 / 3 I put plus because negative times negative is plus
m = -4 / 3 negative 6 plus 2 is -4
To find y2, y1, x2 and x1 you have look on the two points that they gave you.
(2, -2), The x1 is 2 and y1 is -2
(5,-6), The x2 is 5 and y2 is -6

cups of flour.
Answer:
4 cups of sugar require 14 cups of sugar
Step-by-step explanation:
Given
[tex]\frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar[/tex]
Required
Determine the cups of flour for 4 cups of sugar
First, we need to determine the unit rate for 1 cup of sugar.
This is done by multiplying both sides by 4
[tex]4 * \frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar * 4[/tex]
[tex]\frac{7}{2}\ cup\ flour = 1\ cup\ sugar[/tex]
Next, we determine cup of flour for 4 cups of sugar.
This is done by multiplying both sides by 4
[tex]4 * \frac{7}{2}\ cup\ flour = 1\ cup\ sugar * 4[/tex]
[tex]2 * 7\ cup\ flour = 4\ cup\ sugar[/tex]
[tex]14\ cup\ flour = 4\ cup\ sugar[/tex]
Hence;4 cups of sugar require 14 cups of sugar

Answer: 3a^2+6ab+3b^2-2a-2b-1
Step-by-step explanation:
For G(x), we must plug in (a+b) into G(x):
G(a+b) = 3(a+b)^2-2(a+b)-1
= 3(a+b)(a+b)-2(a+b)-1
= factor: 3(a^2+ab+ab+b^2)- (2a+2b)-1
= multiply: 3a^2+3ab+3ab+3b^2-(2a+2b)-1
= now factor the last part: 3a^2+3ab+3ab+3b^2-2a-2b-1
= add/subtract: 3a^2+6ab+3b^2-2a-2b-1

Answer:
Answer: 3a^2+6ab+3b^2-2a-2b-1
Step-by-step explanation:
For G(x), we must plug in (a+b) into G(x):
G(a+b) = 3(a+b)^2-2(a+b)-1
= 3(a+b)(a+b)-2(a+b)-1
= factor: 3(a^2+ab+ab+b^2)- (2a+2b)-1
= multiply: 3a^2+3ab+3ab+3b^2-(2a+2b)-1
= now factor the last part: 3a^2+3ab+3ab+3b^2-2a-2b-1
= add/subtract: 3a^2+6ab+3b^2-2a-2b-1
Answer: 3a^2+6ab+3b^2-2a-2b-1
Step-by-step explanation:
solve for b please help me
Answer:
B = 7 (?)
Step-by-step explanation:
(b + 3) / 5 = 2
5 (b + 3) / 5 = 2 x 5
Simplify it --> b + 3 = 10
b + 3 - 3 = 10 - 3 (subtract 3 from both sides)
B = 7

question number 36 the answer is always true because rational numbers are numbers that can be turned into fractions or simple fractions easily and any integers that is positive added together will provide a positive answer.
37. the answer is always true because and a negative integer and a negative integer added together will give a negative answer.
38. sometimes true. a positive intergee plus a negative interger can give a positive or negative answer. eg -3+2=-1 but -4+8=4
39. always true. + multiply + =+
40. never true. - multiply - = +

Which numbers go in the blanks?
We need two numbers that...
Add together to get -4
Multiply together to get -60
Can you think of the two numbers?
Try 6 and -10:
6+-10 = -4
6*-10 = -60
Fill in the blanks in
(v+_)(v+_)
with 6 and -10 to get...
(v+6)(v-10)

Jillian is using integer tiles to add 7 + (negative 2). She uses the steps below. Step 1 7 positive tiles. Step 2 7 positive tiles and 2 negative tiles. Step 3 7 positive tiles and 2 negative tiles. 2 positive and 2 negative tiles are circled. Step 4 7 + (negative 2) = 2 Jillian has made an error. In which step does it occur? Step 1 Step 2 Step 3 Step 4 Mark this and return
Answer:
Step 4Step-by-step explanation:
Given the expression 7+(-2)
Let 7 be 7 positive tiles since it is a positive number
Let -2 be 2 negative tiles being a negative number
7+(-2) = 7 positive tiles and 2 negative tiles
note that + * - will give minus sigh (-), the expression will become:
7+(-2) = 7-2
7-2 = 5
Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.
Hence Jillian made an error in step 4

What is a characteristic of all cubic functions? (Pictures included)
Answer:
I believe it's A: They are always increasing.
Step-by-step explanation:
The cubic function is one where the coefficient a, b, c, and d are correlational the variable are real numbers and are polynomial numbers. The function is either one or three real roots. The graph of the function is a cubic curve.
The example of a cubic function is that of the forms of y = ax3 + bx2 + cx + d, where the a, b, c, and d are constants. The cube root function is inverse to the cube function.Hence they are increasing option A is correct.

find the vertex parabola of f(x)= (x+1)² -3? please I need it right away
Answer:
(-1, -3)
Step-by-step explanation:
y = a(x – h)^2 + k, then the vertex is the point (h, k)
f(x) = (x+1)^2 - 3
so h = -1, and k = -3
so the vertex is (-1, -3)

We went to the market to buy some fruit. We decided to buy some apples, strawberries, and oranges. If we buy 2 apples, 3 boxes of strawberry, and 4 oranges, the fruit would cost $15.30. If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90. If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70. Use the Gaussian Elimination Method to solve for the price of each fruit.
Step-by-step explanation:
Let the amount of apples bought be x
Amount of strawberries bought be y and;
amount of oranges bought be z
If we buy 2 apples, 3 boxes of strawberry, and 4 oranges, the fruit would cost $15.30, then this will be expressed as;
2x+3y+4z = 15.30 ........... 1
If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90, this will be expressed as:
4x+y+2z = 10.90 ......... 2
If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70, this is expressed as:
5x+2y+x = 13.70 .......... 3
Solving the three equations simultaneously:
2x+3y+4z = 15.30 ........... 1
4x+y+2z = 10.90 ......... 2
5x+2y+z = 13.70 .......... 3
Reduce the number of equations
multiply equation 1 by 2 and subtract from equation 2
equation 1 * 2 will give:
4x+6y+8z = 30.6 ........... 4
eqn (4)-eqn(2)
6y-y + 8z-2z = 30.6-10.90
5y+6z = 19.7 ......... 5
Also multiply equation 2 by 5 and eqn 5 by 4 and subtract from each other.
eqn(2)* 5 will give:
20x+5y+10z = 54.5 .......... *
eqn(3) * 4 will give
20x+8y+4z = 54.8.......**
Subtsrct ** from *
8y-3y+(4z-10z)= 54.8-54.5
5y-6z = 0.3 .................. 6
Equate 5 and 6 and solve:
5y+6z = 19.7 ......... 5
5y-6z = 0.3 .................. 6
subtract:
6z+6z = 19.7+0.3
12z = 20
z = 20/12
z = 1.67
Substitute z = 1.67 into eqn 6
5y-6(1.67) = 0.3
5y - 10 = 0.3
5y = 10.3
y = 10.3/5
y = 2.06
Substitute z = 1.67 and y = 2.06 into equation 1
From 1:
2x+3y+4z = 15.30
2x+3(2.06)+4(1.67) = 15.30
2x+6.18+6.68 = 15.30
2x+12.86 = 15.30
2x = 15.30-12.86
2x = 2.44
x = 2.44/2
x = 1.22
Therefore 1 apple costs $1.22, 1 strawberry costs $2.06 and 1 orange costs $1.67
