Answer:
a. y = (3/5)× x +1
Step-by-step explanation:
y= mx+c
m = (13-4)/(20-5) = 9/15 = 3/5
c= 1
so, y= mx+c becomes y= (3/5) × x +1

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
<em>q</em> = -7
<em>r</em> = 2
<em>s</em> = q
8 - 8r - 3s + 6q
<u>Step 2: Simplify</u>
- Substitute in variables: 8 - 8(2) - 3q + 6q
- Multiply: 8 - 16 - 3q + 6q
- Combine like terms: 3q - 8
Answer:
As the picture shows, we have
V = (x+5)(x-2)x =30x
<=> x(x^2+3x-10) =30x
<=> x^3 + 3x^2-10x-30x = 0(*)
<=> x^3 +3x^2 -40x = 0
<=> x(x-5)(x+8) =0
Solve for (*), there are 3 solution :
5,
0(invalid),
-8(invalid)
=> 3 dimensions of rectangular box: 5, 3, 10
60 percent because if you divide if you multiply 18 by 100 it gives you 18000 then divide it by 30 it gives you 60
