Answer:
A is the correct answer
Step-by-step explanation:
We need to figure out the base and the height. We can do that using pythagorean's theorem.
The others either misused the pythagorean theorem or got the 1/2*base*height formula wrong, so A is the answer.

Billy bought 2 sweatshirts and 3 t-shirts. His friend Jordan bout 3 sweatshirts and 3 t-shirts. Billy's bill was $35 and Jordan's bill was $45. What is the price of one t-shirt and what is the price of one sweatshirt?
Answers
for billy: 2x+3y=35$
for jordan:3x+3y=45$
We need to get rid of one of the unknowns inorder to solve, therefore we will subtract the two equations from each other. This will get rid of the y variable(3y-3y=0)
2x+3y=35$
-
3x+3y=45$
=
-1x=-10$
we get rid of the negative, which leaves us with x=10$. Knowing this info, we can now easily calculate y:
2x+3y=35$
2(10)+3y=35$
20+3y=35$
3y=15
y=15/3
y=5

Step-by-step explanation:
AB = 72 so, then FB would be half of that
so 72 divided by 2 would be 36
5x+1=36 then do substitution
-1 from both sides (from +1 you gotta do the inverse)
5x = 35
divide 5 from both sides because in between 5 and x is a times so the inverse of that is divide

At a local fair, Molly sells bracelets. It costs her
$10 per bracelet for supplies and the local marke
charges her a one-time booth fee of $60. She
charges $20 for each bracelet.
a) Write a system of equations to represent this
situation (one equation for expenses and one
equation for income):
Answers
Answer:
10x + 60 ; 20x
Step-by-step explanation:
Given that:
Purchase price per bracelet = $10
Cost of booth = $60
Selling price per bracelet = $20
Hence,
Let number of bracelets = x
Expense equation :
(Price per bracelet * number of bracelet) + booth fee
(10 * x) + 60
10x + 60
Income equation :
Selling price * number of bracelets

Find the missing side length, N.
Answers
We know these triangles are congruent. To find the missing side, you first have to find out what the scale factor is. To do this you can just divide side QS by side AC, which would give you 2.5.
You would then multiply this scale factor by side BC, giving you side N, which is 15.
We know these triangles are congruent with the missing side, N would be equal to 15.
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
We know these triangles are congruent.
To find the missing side, N
ΔABC ≅ΔQRS
AC/QS = BC/RS
2/5 = 6/n
n = 6 x 5/2
n = 30/2
n = 15
Thus, the value of N is 15.

Step-by-step explanation:
look at the equation and insert the value of X from the table into the equation and figure out which one will give you the same sum for the values. for example f(x) = 3(-2)-1
this answer gives you f(x)= -6 -1 which will give u a sum of -7
another one : f(x)= 3(0)-1
3 multiplied by 0 gives you 0 therefore you are left with -1
by doing this you prove that this equation works with ur x values and gives you the same sum you have for f(x)

A hair stylist offers haircuts and hair coloring to his customers. A haircut costs $18 and hair coloring costs $42. Yesterday, the hair stylist had 12 customers and earned a total of $288. How many of the hair stylists customers received hair coloring yesterday
Answers
Answer:
haircut =9 and hair color= 3
Step-by-step explanation:
Step one:
GIven data
let the haircut be x
and hair color be y in numbers.
so
18x+42y=288------------1
x+y=12---------------------2
from 1
x=12-y, put this in 2, we have
18(12-y)+42y=288
216-18y+42y=288
collect like terms
24y=288-216
24y=72
divide both sides by 24
y=72/24
y=3
put y= 3 in 2
x+3= 12
x= 12-3
x=9

run: -1 - (-3) = 2
m1 = 7/2
L2:
rise: 2 - 4 = -2
run: 7 - 0 = 7
m2 = -2/7
parallel means same slope m1 = m2
perpendicular means opposite reciprocal (flip and change signs)
7/2 flip and change signs = -2/7, yes thus it is perpendicular

Write an equation in slope-intercept form of the line with slope −4/5 that contains the point (−5,−4)
.
y=−45x−5
y=−4/5x−8
y=−4/5x−4
y=−4/5x+4
Answers
Our point is (-5, -4)
Now use point slope form to find the equation: (y - y1) = m(x - x1)
(y - y1) = m(x - x1)
(y - (-4)) =-4/5(x - (-5))
y + 4 = -4/5x +4
An equation in slope-intercept form of the line is y = -4/5x - 8. The correct option is B.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the slope −4/5 contains the point (−5,−4). The equation of the line is written as,
y = mx + c
-4 = -4/5 x - 5 + c
-4 = 4 + c
c = -8
The equation will be written as,
y = -4/5x - 8
