what is the value of x in the equation 24 equals 12 - 4x
Answers
Answer:
x = -3
Step-by-step explanation:
24 = 12 - 4x
24 - 12 = -4x
12 = -4x
12/-4 = x
x = -3
Answer:
x=-3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
24=12−4x
24=12+−4x
24=−4x+12
Step 2: Flip the equation.
−4x+12=24
Step 3: Subtract 12 from both sides.
−4x+12−12=24−12
−4x=12
Step 4: Divide both sides by -4.
−4x
−4
=

Answers
Answer: $4603.82
Step-by-step explanation:
Given
The initial cost of a car is [tex]P=\$20,000[/tex]
The rate of depreciation is [tex]i=12.5\%[/tex]
Depreciated value after n years is given by
[tex]\Rightarrow P(1-\frac{i}{100})^n\quad \text{where n=no. of years}[/tex]
Value after 11 years
[tex]\Rightarrow 20,000(1-\frac{12.5}{100})^{11}\\\\\Rightarrow 20000(0.875)^{11}=\$4603.82[/tex]

Answer:
1) w = x+2
2) L = 12
3) w = 9
4) A = 108
Step-by-step explanation:
The rectangle has a length of x+5 and a perimeter of 4x+14.
Perimeter of a rectangle is given by all the lengths plus all the widths, ie 2*width and 2*length.
Perimeter = 2w + 2L
4x+14 = 2w + 2(x+5)
4x + 14 - 2x - 10 = 2w
w = 2x + 7 - x - 5
w = x+2 Width of the rectangle in terms of x.
If perimeter of rectangle is 42, what is the length?
Perimeter = 42 = 4x+14
28 = 4x
x = 7
L = x+5
L = 7+5
L = 12
If perimeter of rectangle is 42, what is the width?
Perimeter = 42 = 4x+14
28 = 4x
x = 7
w = x+2
w = 7+2
w = 9
Area equals length times width. What is the area of the rectangle.
A = L*w
A = 12*9
A = 108

A line that is parallel to the line y=3x-8 and passes through the point (-1,6)
The equation of the parallel line is...
Answers
Answer:
y = 3x + 9
Step-by-step explanation:
If the line is parallel, that means it will have the same slope. So, the line will also have a slope of 3.
Using y = mx + b, plug in the slope and given point, and solve for b:
y = mx + b
6 = 3(-1) + b
6 = -3 + b
9 = b
Plug in the slope and b into y = mx + b
y = 3x + 9
So, the equation of the parallel line is y = 3x + 9
