Answer:
4.5 -3
Step-by-step explanation:
Answer: x = -15
Step-by-step explanation:
Think PEMDAS
First, we factor the parenthesis:
-4 (x-4) = -4(x) + -4(-4)
now we are left with -4x + 16 = -44
Next is to isolate the "x":
to do this, we must subtract 16 from -44
-44 - 16 = 60
now we have -4x = 60
Now we divide both sides by -4 in order to isolate "x"
dividing -4x/-4 = x
diving 60/-4 = -15
the answer is x= -15
Answer:
(Choice B)
Step-by-step explanation:
(7, 0)
7 - 7 = 0
Here, we can see that when 7 is subtracted from x, we get 0 (our y)
Hope this helps!
Answer:
169 cm^2
Step-by-step explanation:
Right surface (rectangle)
A = LW = 7 cm * 5 cm = 35 cm^2
Left surface (hidden rectangle)
A = LW = 7 cm * 5 cm = 35 cm^2
Bottom surface (hidden rectangle)
A = LW = 9 cm * 5 cm = 45 cm^2
Front face = back face = 2 * triangle
A = 2 * bh/2 = 2 * 9 cm * 6 cm/2 = 54 cm^2
total surface area = 35 cm^2 + 35 cm^2 + 45 cm^2 + 54 cm^2 = 169 cm^2
The slope of the line would be -2/3x but the answer to the equation is y= 6-2/3x
