The expected value of y when x is equals to 45 in the equation is 35.06
<h3>How to find variable from an equation?</h3>
The equation is given as follows;
y = -2.61x + 152.51
where
- x = variable 1
- y = variable 2
Therefore,
when
x = 45
y = -2.61x + 152.51
y = -2.61(45) + 152.51
y = - 117.45 + 152.51
y = 35.06

Answer:
3x - 4y = -32
Step-by-step explanation:
How much are the owner's expenses for 10 days?
10 * 130 = $1300
How much money does the owner make selling pizzas per day?
200 * 3 = $600
How much money does the owner make selling sandwiches per day?
85 * 2 = $170
In one day, the owner sells 600 + 170 = $770 worth of pizza and sandwiches
Over the course of ten days, that is 10 * 770 = $7700
Profit = revenue - cost = 7700 - 1300 = $6400
There ya go
Answer:
D
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = 2 and (a, b ) = (- 2, 1 ) , then
y - 1 = 2(x - (- 2)) , that is
y - 1 = 2(x + 2)
