So you plug in 5 for x
-8(5)+1=f(x)
-40+1
-39=f(x)
Kindly find required figure in the picture attached below :
Answer:
14 feets
Step-by-step explanation:
From Trapezoid ABCD ;
The longer base, AD = 7 feets
Shorter Base ; BC = 5 feets
The Trapezoid GHIJ
Shorter Base = HI
Longer base = GJ
Given that the scale factor between ABCD and GHIJ is 2 ; then
GJ is similar to AD
Hence, side GJ = 2 * length of AD
GJ = 2 * 7 = 14 feets
Answer:
a = -0.6b + 0.2c
Step-by-step explanation:
Simplifying
5a + 3b = c
Solving
5a + 3b = c
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3b' to each side of the equation.
5a + 3b + -3b = -3b + c
Combine like terms: 3b + -3b = 0
5a + 0 = -3b + c
5a = -3b + c
Divide each side by '5'.
a = -0.6b + 0.2c
You can solve this two ways:
One is by substituting in the numbers until you get 15=15.
6(0)-9=15
0-9=15
-9=15
6(1)-9=15
6-9=15
-3=15
6(2)-9=15
12-9=15
3=15
6(3)-9=15
18-9=15
9=15
6(4)-9=15
24-9=15
15=15
Solution is x=4
or you can find the value of x
by first adding 9 to both sides to get x by itself
6x-9=15
6x=24
Then divide by 6
x=4
Put 7 in place of x 10-2(7)= 10-14=negative 4
