First find what g(-1) and h(-1) is.
g(-1) means that x is -1. To find g(-1), look on the graph at x = -1 and find its y value. The y value, or g(-1) = -2.
To find h(-1), plug in -1 for "x" in the equation
h(x) = -3x + 8
h(-1) = -3(-1) + 8
h(-1) = 3 + 8
h(-1) = 11
So:
g(-1) = -2
h(-1) = 11
g(-1) is l<u>ess than</u> h(-1)
Answer:
The numbers are 56, 280 and 156
Step-by-step explanation:
Let
x -----> the first number
y ----> the second number
z ----> the third number
we know that
y=5x -----> equation A
z=x+100 ----> equation B
x+y+z=492 ----> equation C
Solve the system of equations by substitution
substitute equation B and equation A in equation C and solve for x
x+5x+x+100=492
7x=492-100
7x=392
x=56
<u><em>Find the value of y</em></u>
y=5x -----> y=5(56)=280
<u><em>Find the value of z</em></u>
z=x+100 ----> z=56+100=156
therefore
The numbers are 56, 280 and 156
Use the Pythagorean theorem
let = length of ram = l
l² = 4² 18²
l² = 16 + 324
l² = 340
l = 18.4390889146
l = 18.4 ft.
