Answer:
Step-by-step explanation:
We want to make equation into slope intercept form.
Like this: y=mx+b
(mx and b are interchangeable)
Step 1) Convert equation
8x-5y=-11
Sub Step a) subtract 8x on both sides
8x-5y=-11 => -5y = -11-8x
-8x -8x
Sub step b) get y alone
-5y/-5 = -11/-5 - 8x/-5
Equation: y = 11/5 + 8x/5
Step 2) Y-intercept
B is the y-intercept.
B = 11/5
y-intercept is (0,11/5)
Step 3) X-intercept
Substitute 0 for y in our equation
0=11/5+8x
Subtract 8x on both sides
-8x = 11/5
Divide by -8 on both sides
x = -11/40
x-intercept is (-11/40,0)
A’=(1,.5) you just multiply the points by whatever the dilation is, so by .5
Answer:
Number of year(n) = 3.4 year (Approx)
Step-by-step explanation:
Given:
Purchase value of car = $27,000
Depreciation rate per year (d) = 18% = 0.18
Future price = half of its original value = $27,000 / 2 = $13,500
Find:
Number of year(n) = ?
Computation:

Number of year(n) = 3.4 year (Approx)
60 percent of 1200 is 720 if that’s what you mean
3/5 × 15= 9
therefore 9 students packed lunch
