if y(x) = 5x-2 and g(x) = 2x + 1, find (f + g)(x).
Answers
Answer:
(f + g)(x) = 7x - 1
Step-by-step explanation:
Given : f(x) = 5x – 2 and g(x) = 2x + 1
We have to find (f + g)(x)
Consider (f + g)(x) = f(x) + g(x)
Also, given f(x) = 5x – 2 and g(x) = 2x + 1
Substitute, we have,
f(x) + g(x) = 5x - 2 + 2x + 1
LIKE TERMS are terms having same variable with same degree.
Simplify by adding like terms, we have,
f(x) + g(x) = 5x + 2x - 2 + 1
f(x) + g(x) = 7x - 1
Thus, (f + g)(x) = 7x - 1

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
From the equation, the y-intercept is 10. Then the equation is given as,
y = mx + 10
From the graph, the line is passing through (2, 8). Then the slope is given as,
8 = m(2) + 10
8 = 2m + 10
- 2 = 2m
m = - 1
The equation for the line shown in the graph will be y = - x + 10. Then the correct option is D.

(Add 48 to both sides)
(Divide both sides by -4)
(Simplify both sides of the equation)
(Add 2y to both sides)
(Add -108 to both sides)
(Divide both sides by 49/2)
(Simplify both sides of the equation)

The statement true about the angle bisector AD of triangle ABC is; AD is a perpendicular bisector of BC.
What are angle bisectors?Angle bisectors are lines that bisect the considered angle. Bisect refers to splitting into two equal parts. Therefore, the bisected parts of the considered angle are half of the original angle.
When an angle bisector points so, the two sides of the corner are equidistant. Its corner bisector of a triangle angle is a straight line splitting its angle into two congruent directions.
In such a single point, calling its incentives, which follow three-angle engineers are required of its three triangle angles.

y=3y-12
-3y from both sides
-2y=-12
y=6
Answer:
x = 1 and y = 6
Step-by-step explanation:
so the opposite sides are equal to each other, therefore
4x + 7 = 12x - 1
and y + 1 = 3y - 11
so for the xs
start by adding 1 to each side
4x + 8 = 12x
subtract 4x from both sides
8=8x
divide by 8
x=1
for the ys
subtract one from each side
y= 3y -12
subract 3y from each side
-2y=-12
divide by -2

Factor out the greatest common factor of Given the expression: 4x^10 − 64x^2
Answers
Part A
4x10 – 64x2
= 4x2 * x8 – 4x2 * 16
= 4x2 * (x8 – 16) by distributive property
Part B
x8 is (x4)2 and 16 = 42 so a difference of squares is seen in the parentheses. The pattern a2 – b2 = (a + b)(a – b) can be used.
4x2 * (x8 – 16)
= 4x2 * (x4 + 4) * (x4 – 4)
x4 = (x2)2 and 4 = 22 so there is another difference of squares in the last factor. Use the pattern again.
= 4x2 * (x4 + 4) * (x2 + 2) * (x2 – 2)
Answer:
Below.
Step-by-step explanation:
The GCF = 4x^2
So its 4x^2(x^8 - 16)
This can be further factored
= 4x^2(x^4 - 4)(x^4 + 4)
= 4x^2(x^2 - 2)(x^2 + 2)(x^4 + 4)
