What is the answer to number 39

Parallel lines have the same a slope.

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have y = -2x - 6 → the slope m = -2. Therefore we have the equation of a line:

y = -2x + b

Put the coordinates of the point (-4, 1) to the equation:

1=-2(-4)+b

1=8+b               <em>subtract 8 from both sides</em>

-7=b\to b=-7

<h3>Answer: y = -2x - 7</h3>

Answer: The snack shop sells granola bars for a lower price.

Step-by-step explanation:

First you should plug in the number of bars for each equation, if you get one bar from the snack shop the price would be $1.25, I'm going to fill in the table to help you better understand.

y= 1.25(2) 2.50

y= 1.25(3) 3.75

y= 1.25(4) 5.00

y= 1.25(5) 6.25

This table was all for the snack shop.

Answer:

8 is the length of JB

Step-by-step explanation:

<u>Key skills needed: Equations, Congruence</u>

1) We need to find out an equation to make based on the lengths that are given. ΔJMB is congruent to ΔKMB because of Side-Angle-Side:

  • JB is congruent to BK
  • Angle MBK would be a right angle, since it is supplementary to the right angle JBM. Since both are right angles they are congruent.
  • Both triangles have the side BM. Using the reflexive property, BM is congruent to itself, so there you go --> Side-Angle-Side

2) Now since both triangles are congruent, we can make the equation that the length of JM is congruent to the length of MK, using the fact that: If triangles are congruent, then corresponding parts are congruent.

3) This means that 16x -24 = 4x

Subtract 16x from both sides : -24 = -12x

Divide by -12 on both sides and get x = 2

4) Substitute x into the length of JB (16x-24)

16(2)-24 = 32-24 = 8

5) Therefore, the length of JB is 8

Find the integer values of x that satisfy both of these inequalities.
Shtirlitz [24]

Answer:

0, 1, 2.

Step-by-step explanation:

5 - 3x <= 7

-3x <= 2

x >= -2/3      (the inequality sign flips as we are dividing by a negative value)

4x + 1 < 13

4x < 12

x < 3.

So the integer values satisfying the inequalities are>

0, 1, 2.

Mr.Endo buys 13.6 gallons of gasoline. He pays $3.95 per gallon. How much does Mr.Endo spend on gasoline
makkiz [27]

Cost per gallon of gasoline = $3.95 per gallon.

Total number of gallons of gasoline Mr.Endo buys = 13.6 gallons.

We need to find the total cost of 13.6 gallons of gasoline.

<em>In order to find the total cost of 13.6 gallons of gasoline, we need to multiply it by cost of each gallon of gasoline.</em>

Therefore, cost of 13.6 gallons of gasoline = 13.6 × 3.95

On multiplying 13.6 by 3.95, we get 53.72.

<h3>Therefore, Mr.Endo spend a total $ 53.72 on gasoline.</h3>
