Simon charges an initial fee plus an hourly fee to repair TVs. The table below shows the amounts Simon charges for the first thr
Sedbober [7]

Answer:

Rate of change: 25

Initial value: 25

Equation: y = 25x + 25

Step-by-step explanation:

✔️hours = x

Fee = y

Rate of change (m) = ∆y/∆x

Rate of change (m) = 25/1 = 25

Rate of change (m) = 25

✔️Initial value = y-intercept (b).

To find the initial value, simply substitute (x, y) = (1, 50) and m = 25 into y = mx + b.

Thus:

50 = (25)(1) + b

50 = 25 + b

Subtract 25 from each side

50 - 25 = b

25 = b

b = 25

✔️To write an equation, substitute m = 25 and b = 25 into y = mx + b.

Thus:

y = 25x + 25

We are given that the total number of students is

700

The survey results is 80% likes the new lunch menu

We are expected to establish what amount of students is 80%

=80/100*700

=0.8*700

=560

Hence 80% of 700 is 560

Find the value of x if the points (x,5) and (3,7) lie on the line whose slope is 4/7
muminat

Answer:

x = -4

Step-by-step explanation:

Write and solve an equation in which the slope from the definition of slope is on the left side and the given slope, 4/7, is on the right side:

        7 - 5          4

m = ---------- = --------

         3 - x         7

Simplifying with the aim to find the value of x:

2(7) = 4(3 - x), or 7 = 3 - x.  Then x = -4.
