It's a linear function in slope-intercept form (y = mx + b)
f(x) = 4 - 4x = -4x + 4
m = -4, b = 4.
Domain of a linear function is the set of all real numbers.
Range of a linear function where m ≠ 0 is the set of all real numbers.

Answer:
64 miles
Step-by-step explanation:
If he used 20% of the gas, he can go 20% of the miles
20% of 320 miles
.20 * 320
64 miles
Answer:
Yes, Chloe fill out her math journal correctly.
Step-by-step explanation:
Total number of math problem = 100
Problems solved on Friday = × 100 = 39
Problems solved on Saturday = × 100 = 50
Problems solved on Sunday = 15
Total number of math problem in three days = 39 + 50 + 15 = 104
But the student have only 100 math problems to solve in three days . so he achieved the target. thus Chloe fill out her math journal correctly.
Let's get this equation into a usable format, which is
<em>y=mx+b</em><em /> (where m is the slope and b is the y-intercept), before graphing.
First, we move our x terms onto one side, so that the y terms are on one side, and the x terms on another side. Keep in mind that this will negate (multiply by -1) the x term we move.
<em>2y = -5x - 10</em>
Then we isolate y. We'll do this by dividing by 2.
<em>2y/2 = -5/2x - 10/2</em>
y = -5/2x - 5We now have the equation in y=mx+b format. We can now graph (it should look something like the one below).
Slope: -5/2
Y-Intercept: -5:)
