I would go with Option B, List the factors of the constant term.

For ax² + bx + c, you would find the factors of A * C that would add up to B. So if term A is a 1, you would just take the factors of term C, the constant.

Answer:

the slope represents the cost for each hour it takes to repair the machine.Step-by-step Answer:

We are given that the cost of a service call to fix a washing machine can be expressed by the linear function

Where

y=Total cost of a service to fix the machine.

x=Number of hours takes to fix the machine

We have to find that slope in this function what represents.

General equation of line is given by

Where m=Slope of line

c=y- intercept

Comparing the general equation with the given function

We get m=45,c=35

m=45 represents the cost for each hour it takes to repair the machine because when number of hours multiplied by 45 then we get total cost of x hours.

Hence, the slope represents the cost for each hour it takes to repair the machine.

For what value of a do the lines 5x–2y=3 and x+y=a intersect at a point on the y-axis?

inna [77]

Answer:

a = -3/2

Step-by-step explanation:

You can set x=0 and solve for y to find the y-intercept in each case.

first equation: y-intercept = -3/2

second equation: y-intercept = a
