Answer:
y = 2x + 1
Step-by-step explanation:
[tex]m = \frac{-3 - 7}{-2 - 3}\\ = \frac{-10}{-5}= 2\\y = mx + b \\y = 2x + b\\7 = 2(3) + b\ -> 7 = 6 + b \\b = 1 \\y = 2x + 1[/tex]

Please Help. Given trapezoid ABCD, Prove ΔBEC ~ ΔDEA
Answer:
AAA (or AA)
Step-by-step explanation:
Prove ΔBEC ~ ΔDEA
(using three angles is unnecessary because you can just use Angle Angle to prove similarity)
First, m∠BCE = m∠EAD because of alternate interior angles.
Then, m∠ADE = m∠CBE because of alternate interior angles.
m∠BEC = m∠AED because of vertical angles
Thus, ΔBEC ~ ΔDEA because of Angle Angle Angle [AAA] (or AA if you only chose to use 2 angles)

3w+2=29(Multiply both sides by w)
3w2+2w=29w(Multiply both sides by w)
3w2+2w−29w=29w−29w(Subtract 29w from both sides)3w2−27w=0
3w(w−9)=0(Factor left side of equation)
3w=0 or w−9=0(Set factors equal to 0)
w=0 or w=9
Check possible critical points.

Jackson’s car was making a rumbling noise for two weeks. He decided to take it to the mechanic to get it checked out. To diagnose the problem, the mechanic tells Jackson that he charges a flat fee of $60 and $35 for each hour he spends trying to identify the problem.
A. Write a linear equation in y = mx+b form to represent the cost of getting Jackson’s car diagnosed.
B. Identify the slope and y-intercept, and what they mean in the context of the story.
C. Does this situation represent a proportional relationship? Why or why not?
Answer:
y=35x+60
slope-35 y intercept-60
proportional relationship
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = 35x + 60
Slobe 35
y-intercept 60
The y-intercept is the start cost and the slope is how much it will go up per hour.
It is proportional because it is going up by 35 every hour
Jerry is saving his money. He started with $15.00. If he adds $10.00 to his savings
each month, how much will he have saved after 2.5 months?
Answer:
$40
Step-by-step explanation:
use y = mx + b
y = amount saved = ?
m = amount saved per week = $10
x = time (in months) saving = 2.5
b = money jerry started with = $15
plug in:
y = (10)(2.5)+15
y = $40

3(3x + 2y) and 9x + 6y
3(3x + 4y) and 9x + 12y
3(x + 4y) and 3x + 12y
3(x + 2y) and 3x + 6y
Answer:
3(3x + 2y) and 9x + 6y
Step-by-step explanation:
3(x + 3y + 2x - y)
= 3 (x + 2x) + (3y - y)
= 3 (3x + 2y)
= (3 • 3x) + ( 3 • 2y)
= 9x + 6y

Spiral Review A chili cook-off has adult tickets a and child tickets C. A group of visitors buys 3 adult tickets and 2 child tickets and pays a total of $26.
Another group buys 5 adult tickets and 3 child tickets and pays $42. Write and solve a system of equations to find the price of each type of ticket.
Enter the correct answers in the boxes.
Equation 1:?
Equation 2:?
adult: $ 6
child: $ 4
I just need help on making equations
Equation 1 would be: 3a+2C
Equation 2 would be: 5a+3C
The system of equations are solved and the cost of adult ticket and child tickets are $ 6 and $ 4 respectively
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the adult tickets be a
Let the child tickets be c
Group A buys 3 adult tickets and 2 child tickets and pays a total of $26
So , 3a + 2c = 26 be equation (1)
And , Group B buys 5 adult tickets and 3 child tickets and pays $42
So , 5a + 3c = 42 be equation (2)
On simplifying , we get
Multiply equation (1) by 5 and equation (2) by 3 , we get
15a + 10c = 130 be equation (3)
15a + 9c = 126 be equation (4)
Subtracting equation (4) from equation (3) , we get
c = $ 4
Therefore , the cost of child ticket is $ 4
Substituting the value of c in equation (1) , we get
3a + 2 ( 4 ) = 26
3a + 8 = 26
Subtracting 8 on both sides , we get
3a = 18
Divide by 3 on both sides , we get
a = $ 6
Therefore , the cost of adult ticket is $ 6
Hence , the system of equations are solved

• Demand equation: 0.7x + y = 340
Supply equation: -1.5x + y = 320
1. Solve the system algebraically to determine the balance point between
supply and demand.
Answer:
Step-by-step explanation:
Subtract equation 2 from equation 1
.7x+y-(-1.5x+y)=340-320
.7x+y+1.5x-y=20
2.2x=20
x=100/11, then use this in either original equation to find y.
.7(100/11)+y=340
y=3670/11, so the balance point is
(100/11, 3670/11)

To find the volume, we multiply 12 by the height and then by 3.14. So for 1, we get 1*12 which equals 12, then we multiply that by 3.14 and we get 37.68. So we do that for all of them.
1*12*3.14 = 37.68
3*12*3.14 = 113.04
5*12*3.14 = 118.4
7*12*3.14 = 263.76
