Answer: correct answer is D

That is, If the average meal price increases by $1, the number of daily customers decreases by 18.

Step-by-step explanation:

Given that the linear model below represents this situation, where x is the average meal price (in dollars), and y is the number of daily customers.  Interpret the slope.

y = 437 - 18x

Since x = the average meal price.

and

y is the number of daily customers.

Let x = 1

Y = 437 - 18 = 419

If x = 2 then

Y = 437 - 36 = 401

The difference between the number of daily customers is

419 - 401 = 18

Therefore, If the average meal price increases by $1, the number of daily customers decreases by 18.

Can someone help me please this thrue me off big time
Elena-2011 [213]
Slope = (-12 - 43)/(4 +7) = -55/11 = -5

y = mx + b
43 = -5(-7) + b
43=35+b
b = 8

equation
y = -5x + 8

TV and RI intersect at E. If the measure of IVE=50, the measure of VIE=70 and the measure of RET=2X-10 , find the value of x
Helen [10]

The value of x from the given conditions is 35.

The  line TV and RI intersect at E.

The measure of IVE=50° and the measure of VIE=70°.

Since, the points V, I and E makes a triangle.

Therefore, the total angle inside the triangle is 180°.

Hence,

∠IVE + ∠VIE + ∠VEI = 180°

50°+70°+ ∠VEI = 180°

∠VEI = 180°-50°-70°

∠VEI = 60°

Also the angles ∠VEI and the angle ∠RET are congruent.

Therefore, ∠VEI = ∠RET

60° = 2x-10

2x = 70

x = 70/2

x = 35.

The lines TV and RI intersect at E. If the measure of IVE=50, the measure of VIE=70 and the measure of RET=2X-10. Then the value of x = 35.

1: A bag contains 10 white golf balls and 6 striped golf balls. A golfer wants to add 122 golf balls to the bag. He wants the ra
fgiga [73]
Part A:

Given that a<span> bag contains 10 white golf balls and 6 striped golf balls, the ratio of white to striped golf balls is 10 : 6 = 5 : 3.

Given that </span>a<span> golfer wants to add 122 golf balls to the bag, the of balls each he should add is given by:

5\left( \frac{122}{5+3} \right) \ : \ 3\left( \frac{122}{5+3} \right)=5\left( \frac{122}{8} \right) \ : \ 3\left( \frac{122}{8} \right) \\  \\ =5(15.25) \ : \ 3(15.25)=76.25 \ : \ 45.75 \\  \\ \approx76:46

Therefore, the golfer shold add 76 white golf balls and 46 striped golf balls.



Part B.

You did not indicate the scale factor.

Assuming the scale factor is given by D(o, k) where k can be any number, then the cordinate of the </span><span>coordinates of the image of the quadrilateral VWXY are given by:

V'(6k, 2k), W(-2k, 4k), X(-3k, -2k), Y(3k,-5k)

That is you multiply the scale factor to the coordinates of the preimage to get the coordinates of the image.
