Answer:
-5 is a root
Step-by-step explanation:
It would help to see any possible answers for this if this is a multiple choice question, but if a factor of f(x) is (x+5), then -5 must be a root of a function.
To find roots, set factor equal to zero and solve:
x + 5 = 0
x = -5
On his first three tests, Trevor scored 86, 83, and 78. What score must he get on his fourth test to have an average (mean) of 80 for all four tests?
Answer:
Trevor must score a 73.
Set UpWe will create an equation that has four values (three knowns, one unknown) that will divide by 4 to find the average.
Our equation will look like this:
[tex]\displaystyle \frac{86+83+78+x}{4}=80[/tex]
SolveFirst, combine all like terms.
[tex]\displaystyle \frac{247+x}{4}=80[/tex]
Then, divide the fraction.
[tex]\displaystyle \frac{247}{4} + \frac{x}{4} = 80[/tex]
Subtract 247/4 from both sides of the equation.
[tex]\displaystyle \frac{247}{4} - \frac{247}{4} + \frac{x}{4} = 80 - \frac{247}{4}[/tex]
[tex]\displaystyle \frac{x}{4} = \frac{73}{4}[/tex]
Then, multiply both sides of the equation by 4 to get rid of the denominator and isolate the variable.
[tex]4\times\displaystyle \frac{x}{4} = 4\times\frac{73}{4}[/tex]
[tex]x=73[/tex]
Final Answer[tex]\boxed{\bold{x=73}}[/tex]

A map has a scale of 288 mi to the
inch. How far apart on the map are two cities that, in
reality, are 2016 mi apart? How far apart in reality are
two cities that are 8 in. apart on the map?
The scale of a map is 288 miles per inch. On the map, how far away are two cities that are actually 2016 miles apart? Two cities that are 8 inches apart on a map, how far apart are they in reality?
7 miles per inch far away are two cities that are actually 2016 miles apart and 1.142 miles per inch far away the two cities that are 8 inches apart on a map.
Let us take First two cities as A and B and the next two cities as C and D.
Now,
City A and City B are separated by 288miles per inches.
In reality, the two cities are separated by 2016 miles.
[tex]=\frac{2016}{288}=7[/tex]
The scale on the map for cities A and B is: 7
The same map, however,
what would be the separation between cities C and D,
the true distance between two cities, which is 8 miles.
This issue can be resolved with a proportion.
=[tex]\frac{288}{2016}\times 8[/tex] miles
=[tex]\frac{288\times8}{2016}[/tex] miles
=1.142 miles
Therefore, on the map, 7 miles per inch far away are two cities(A and B) that are actually 2016 miles apart and 1.142 miles per inch far away the two cities(C and D) that are 8 inches apart on a map.

2(2 – 2x) = –3x A. –4 B. 4 C. 6 D. 0
Answer:
[tex]x = 4[/tex]
Step-by-step explanation:
Let's solve:
[tex]2(2−2x)=−3x[/tex]
Step 1: Simplify both sides of the equation.
[tex]2(2−2x)=−3x \\ (2)(2)+(2)(−2x)=−3x(Distribute) \\ 4+−4x=−3x \\ −4x+4=−3x[/tex]
Step 2: Add 3x to both sides.
[tex]−4x+4+3x=−3x+3x \\ −x+4=0[/tex]
Step 3: Subtract 4 from both sides.
[tex]−x+4−4=0−4 \\ −x=−4[/tex]
Step 4: Divide both sides by -1.
[tex] \frac{ - x}{ - 1} = \frac{ - 4}{ - 1} [/tex]
Therefore, the answer will be x = 4.

What are the slope and Y intercept of the line described by Y equals 3X -6
Two parallel lines are cut by a transversal. What is the measure of angle6 ?
Answer:
A
Step-by-step explanation:
Angle 3 and angle 6 are congruent because they are alternate interior angles. Angle 3 plus angle 1 is 180 degrees. So you just subtract 123 from 180 (180-123) and you get 57 degrees.
The measure of angle 6 is 57°
The correct answer is an option (A)
What are parallel lines?"The lines in the same plane that are at equal distance from each other and never meet."
What is transversal?"A line that passes through two lines in the same plane at two distinct points in the geometry. "
What are opposite angles?"The angles directly opposite to each other when two lines intersect in a plane."
For given question,
Line n and line p are parallel lines and line t is the transversal.
Here, angle 1 and angle 4 are opposite angles.
⇒ ∠1 = ∠4
We have been given that ∠1 = 123°
⇒ ∠4 = 123°
Also, angle 4 and angle 6 are interior angles on the same side of the transversal.
We know that each pair of interior angles on the same side of the transversal is supplementary.
⇒ ∠4 + ∠6 = 180°
⇒ 123° + ∠6 = 180°
⇒ ∠6 = 180° - 123°
⇒ ∠6 = 57°
Therefore, the measure of angle 6 is 57°
The correct answer is an option (A)

34°= 9x-2 ( vertically opposite angle)
Vertical Angles (Vertically Opposite Angles) When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.
9x = 36
x = 36/9

∠ IYW = ∠ WAP
SO ∠ WAP = 34°
∠IWY+∠AWI = 180° ( LINEAR PAIR)
So ∠IWY = 90°
∠IWY = ∠ AWP ( vertical opposite angle)
∠ AWP = 90°
In ΔAWP
∠ AWP+∠ WAP +∠ APW = 180°
( sum of all the angle in triangle is 180°)
90°+ 34°+8Y = 180°
124°+ 8Y = 180°
8Y = 180°- 124°
8Y = 56°
Y = 7

Select the correct answer. 3 A linear function has a y-intercept of -12 and a slope of 3/2. What is the equation of the line?
a. y = 3/2x - 12
b.y=3/2x+12
c.y=2/3x-12
d y=-12x-3/2
Answer:
a. y = 3/2x - 12
