Hey there!
4(-x + 4) = 12
4(-x) + 4(4) = 12
-4x + 16 = 12
SUBTRACT 16 to BOTH SIDES
-4x + 16 - 16 = 12 - 16
CANCEL out: 16 - 16 because it gives you 0
KEEP: 12 - 16 because it helps solve for the x-value
NEW (temporary) EQUATION: -4x = 12 - 16
12 - 16 = -4
NEW EQUATION: -4x = -4
DIVIDE -4 to BOTH SIDES
-4x/-4 = -4/-4
CANCEL out: -4/-4 (the LEFT side) because that gives you 1
KEEP: -4/-4 (the RIGHT side) because it gives you the result of the x-value
x = -4/-4
x = 1
Therefore, your answer is: x = 1
Good luck on your assignment and enjoy your day!

Line R passing through point P(-2, -1) and point (3,5). Find the slope of line R.
Answer:
Slope: 6/5
Step-by-step explanation:
For this problem, you'll need to apply the slope formula Y2-Y1
X2-X1.
Let's now assign each number their position in the formula. The first set of parentheses, (-2,-1) is going to translate to (x1,y1). (3,5) will translate to (x2,y2). Now, when you put it all together, you get 5-(-1) / 3-(-2). This would give you 6/5. That would be your slope. You can then proceed to graph it. Hope this helped! :))

write a degree 3 polynomial with zeros 1, 5i, and -5i
Answer:
x^3 -x^2 + 25x - 25
Step-by-step explanation:
x = 1
x = 5i
x = -5i
(x - 1)(x - 5i)(x + 5i)
Multiply
(x - 1)(x^2 + 5ix - 5ix + 25) *Remember that i multiplied by i equals negative and in this situation, one of the variables was already negative, so negative multiplied by negative is positive*
(x - 1)(x^2 + 25)
Multiply again
x^3 + 25x -1x^2 - 25
x^3 -x^2 + 25x - 25

Is x = -2 a function?
Answer:
yes
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
If you graph this function, you'll find that it looks like a vertical line, straight up and down. In a function, each x-value has to have exactly one y-value. In this function, however, any y-value you plug in gives you the same x-value: -2.
The one x-value, -2, has an infinite number of corresponding y-values, so this is definitely not a function.
quadratic form to vertex form with a vertex of (-4,-1) and a y-intercept of 7
If a pair of corresponding angles are complementary, what is the measure of each angle?
Answer:
Step-by-step explanation:
Complementary is adding up to 90 degrees. depends what the other angle is/one of the pair. Subtract that by 90 and you find the other angle.

What is the side length of a square that has an area equal to 49 squared
inches? *
s= 7 inches
s= 6 inches
s= 5 inches
s= 8 inches
Please help me
Answer:
s= 7 inches
Step-by-step explanation:
Let the side length be x
Area of square = side × side OR [tex]side^{2}[/tex] (lets put x in place of side)
[tex]49^{2}[/tex] = x
7 = x
Side length = 7 inches
Answer:
7 inches
Step-by-step explanation:
Area of a square = 49 sq. inches
side *side = 49
side = [tex]\sqrt{49}=\sqrt{7*7} = 7 \ inches[/tex]
Write an algebraic expression for “8.9 times a number.”
A 1-column table with 5 rows. Column 1 is labeled Multiplication Words with entries double, multiply, product, twice, times.
Which would you simplify in order to evaluate the expression when the value of the variable is 2?
8.9/2
8.9 + 2
8.9(2)
(8.92)
Answer:
8.9(2)
Step-by-step explanation:
8.9/2 is division.
8.9+2 is addition.
(8.92) is just adding 2 onto 8.9 which extends the number, not multiplies.
Answer:
8.9(2)

On the first day of a family road trip, Kai's family travels 365 miles.
On the third day, they travel 20% farther.
How many miles does Kai's family travel on the third day?
The number of miles traveled by Kai's family as required in the task content is; 73 miles.
How many miles was travelled on the third day?It follows from the task content that the number of miles traveled by Kai's family on the third day is to be determined.
On this note, since the family travelled 365 miles on the first day and travelled 20% farther on the third day;
The number of miles traveled on the third day can be modelled as;
= 20% of 365
= (20 / 100) × 365
= 73 miles.
On this note, the number of miles traveled on the third day is; 73 miles.
