Answer:
2 years
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year,
then, solving our equation
t = 84 / ( 600 × 0.07 ) = 2
t = 2 years
The time required to
accumulate simple interest of $ 84.00
from a principal of $ 600.00
at an interest rate of 7% per year
is 2 years.

Which statement describes the line that contains the points (5, -6) and (3, -6)?
A. The line is vertical
B. The line is horizontal
C. The line has a positive slope
D. The line has a negative slope
Answer:
B
Step-by-step explanation:
Using the equation to find the slope, (-6 - -6) / (5 - 3) equals zero. This means that the line has no slope and must be flat.
how do you multiply
Answer:
example 7 x 3 means you add 7 3 times
Step-by-step explanation:
solve for x
x- 5/3=1
Answer:
x = 8/3 or 2 2/3
Step-by-step explanation:
x - 5/3 = 1
x - 5/3 + 5/3 = x
1 + 5/3 = 8/3 or 2 2/3
x = 8/3 or 2 2/3
Answer:
x = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
Given
x - [tex]\frac{5}{3}[/tex] = 1 ( multiply through by 3 to clear the fraction )
3x - 5 = 3 ( add 5 to both sides )
3x = 8 ( divide both sides by 3 )
x = [tex]\frac{8}{3}[/tex]

Given (11,2) and (x,−4), find all x such that the distance between these two points is 10. Separate multiple answers with a comma.
Answer: x = 3, 19
Step-by-step explanation:
Given
Two points i.e. [tex](11,2)\ \text{and}\ (x,-4)[/tex] are given
Distance between them is 10 units
Distance is given by the distance formula
[tex]\Rightarrow d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance between two points is
[tex]\Rightarrow 10=\sqrt{(x-11)^2+(-4-2)^2}[/tex]
Squaring both sides
[tex]\Rightarrow 100=(x-11)^2+(-6)^2\\\Rightarrow 100=x^2+121-22x+36\\\Rightarrow x^2-22x+57=0\\\Rightarrow x^2-19x-3x+57=0\\\Rightarrow x(x-19)-3(x-19)=0\\\Rightarrow (x-19)(x-3)=0[/tex]
i.e. [tex]x\ \text{can be }\ x=3\ or\ 19[/tex]

Based on the problem above, how would you rewrite as a binomial squared?
x^2 + 8x - 3 = 0 (x + __ )^2 = __
Answer:
the quadratic equation cannot be written as the square of a binomial
Step-by-step explanation:
Given the expression
x^2 + 8x - 3 = 0
On factorizing
x = -8±√8²-4(-3)/2
x = -8±√64+12/2
x = -8±√76/2
x = -8±8.7/2
Note that since the since the discriminant is not a prefect square, the quadratic equation cannot be written as the square of a binomial

The first number of a pattern is 400. The pattern follows the rule divide by 2, then add 6. What are the next two terms?
Answer:
206 and 109
Step-by-step explanation:
first term:
400 divided by 2 is 200
200+6= 206
second term:
206 divided by 2 is 103
103+6=109
Answer:
206,109
Step-by-step explanation:
If u divide 400 by 2 it equals 200 then u have to add 6 so its 206.
If u divide 206 by 2 it equals 103 then u have to add 6 and u get 109.

Answer:
4th option (x = 60)
Step-by-step explanation:
This is isosceles triangle so the angles are the same. Think of this as an mirror. AE is the same as BE so you can assume angle ABE is 30 degrees.
30+30=60
180-60=120
So angle AEB is 120.
That is supplementary angle so the other side must be 180-120=60.
So, the middle smaller triangle is isosceles as well, so BED and BDE are both 60.
60+60=120, 180-120=60
So angle x = 60

In a baseball card collection, 40% of the cards are worth more than 100$. If 12 cards in the collection are worth more than $100, how many total baseball cards are in the collection?
Answer:
30
Step-by-step explanation:
12 is 40% of the total number of cards.
12 = 0.4x, where x is total number of cards

Council The student council is planning an 8th grade picnic. The local company catering the event will charge a grill rental fee of $150 plus $5 per person for less than 100 students. For 100 students or more, the company will charge the grill fee plus $4.25 per person.
What is the total cost for 125 students?
The total cost for 125 students is $905.5.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Grill rental fee = $150
Charge per person for less than 100 students = $5
Charge per person for 100 students or more = $4.25
Total number of students = 125
The total cost for 125 students is
⇒ [tex][150+5(99)]+[150+4.25(26)][/tex]
⇒ [tex][150+495]+[150+110.5][/tex]
⇒ [tex][645]+[260.5][/tex]
⇒ [tex]905.5[/tex]
Hence we can conclude that the total cost for 125 students is $905.5.

The vertex form of the equation of a parabola is y = (x + 7)2 + 13. What is the standard form of the equation? O A. y = 7x2 + 14x+ 62 O B. y = x2 + 43x + 32 O c. y = x2 + 7x + 13 O D. y= x2 + 14x + 62
Answer:
y = x^2 + 14x + 62
Step-by-step explanation:
y = (x + 7)^2 + 13 is to be rewritten in the form y = ax^2 + bx + c.
Note: Use " ^ " to denote exponentiation.
Expand y = (x + 7)^2, holding the constant term to be added on later:
y = x^2 + 14x + 49 + 13
Combining the constants, we get:
y = x^2 + 14x + 62 (which matches Answer D).

find the measure of the variables and the measures of angles please, HELP ASAP!
9514 1404 393
Answer:
x = 36
78°, 36°, 66° (CW from lower left)
Step-by-step explanation:
The sum of angles in a triangle is 180°, so we can write the equation ...
(2x +6)° +x° +(2x -6)° = 180°
5x = 180 . . . . simplify
x = 36 . . . . . . divide by 5
Then the angle measures are ...
(2x +6)° = (2·36 +6)° = 78°
x° = 36°
(2x -6)° = (2·36 -6)° = 66°
Answer:
Top angle - 36
Left angle - 78
Right angle - 66
Step-by-step explanation:
First to find the angles you need to find x. Do this by adding all the angle measurements and setting them equal to 180 because all triangles equal 180.
x+2x+6+2x-6=180Then, combine like terms
5x=180Finally, divide both sides by 5
x=36Now that you know x you can plug it in to find the rest of the angles. The top angle is simply 36. The left angle is 2(36) + 6, which equals 78. The right angle is 2(36) - 6, which equals 66.
which function is equivalent to f(x)=1/4(x-2)^2+3?
f(x)=1/2x+2
f(x)=1/4x^2-4x+7
f(x)=1/4x^2+4
f(x)=1/4x^2-x+4
Answer: f(6) = (6)2 + 1 = 36 + 1 = 37
If we wanted to find and expression for f(g(x)) we could plug in g(x), which is "x - 4" into the function f(x) wherever we see an "x". So:
f(x) = x2 + 1
f(g(x)) = (x - 4)2 + 1 because g(x) is "x - 4"
