The result from subtracting (-x⁴ + 3x³ + 2x² - 1) from (2x⁴ - x² + 5x - 2) is the algebra expression 3x⁴ - 3x³ - x³ + 5x - 3.
How to solve the expressionWe first open the bracket;
(2x⁴ - x² + 5x - 2) - (-x⁴ + 3x³ + 2x² - 1) = 2x⁴ - x² + 5x - 2 + x⁴ - 3x³ - 2x² - 1
then we collect like terms;
(2x⁴ - x² + 5x - 2) - (-x⁴ + 3x³ + 2x² - 1) = 2x⁴ + x⁴ - 3x³ - x² - 2x² + 5x - 2 - 1
(2x⁴ - x² + 5x - 2) - (-x⁴ + 3x³ + 2x² - 1) = 3x⁴ - 3x³ - 3x² + 5x - 3
Therefore, the solution for the subtraction of the expression (-x⁴ + 3x³ + 2x² - 1) from (2x⁴ - x² + 5x - 2) is the algebraic expression 3x⁴ - 3x³ - 3x² + 5x - 3.

9. Given f(x) and g(x), find f(g(3))
f(x) = x2 +9
g(x) = x - 7
O A) -13
O B) 25
O C) 11
OD) 2
=============================================
Work Shown:
g(x) = x-7
g(3) = 3-7 .... replace every x with 3
g(3) = -4
f(g(3)) = f(-4) .... replace g(3) with -4
f(x) = x^2+9
f(-4) = (-4)^2+9
f(-4) = 16+9
f(-4) = 25
f(g(3)) = 25
-------------------------
Another approach:
f(x) = x^2 + 9
f( g(x) ) = ( g(x) )^2 + 9 ... replace every x with g(x)
f( g(x) ) = ( x-7 )^2 + 9 ... plug in g(x) = x-7
f( g(3) ) = ( 3-7 )^2 + 9 .... plug in x = 3
f( g(3) ) = ( -4 )^2 + 9
f( g(3) ) = 16 + 9
f( g(3) ) = 25

Answer:
$337.12
Step-by-step explanation:
Multiply $1562 by 78.5% (or 0.785) =1230.88
Then subtract the percent of her paycheck spent (1230.88) from the total of her paycheck(1562) to find out how much is missing(the mortgage payment)

Given ∠A and ∠B are vertical angles with m∠A=10x+5 and m∠B=15x−10 .
What is x?
Enter your answer in the box.
The measure of x is 1.
What are vertical angles?Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.
given:
m∠A=10x+5 and m∠B=15x−10 .
As, ∠A and ∠B are vertical angles
so,
m∠A= m∠B
10x +5 = 15x -10
10x - 15x = -10 +5
-5x = -5
x= 1
Hence, the value of x is 1.

Which equation can be used to graph the line that passes through (6, 15) and is perpendicular to the graph of y-7=1/2(x+2)
Answer:
y = -2x + 27
Step-by-step explanation:
Firstly, we shall need to reform the given line equation;
y-7 = 1/2 ( x + 2)
y - 7 = x/2 + 1
y = x/2 + 1 + 8
y = x/2 + 8
Comparing this with y = mx + c
where m is the slope, then the slope of the line is 1/2
Since the line we are looking for has a slope perpendicular to this line, it means that the product of their slopes is -1
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
So we want an equation with slope -2 passing through (6,15)
we use the point slope method here;
y-y1 = m(x-x1)
y-15 = -2(x-6)
y-15 = -2x + 12
y= -2x + 12 + 15
y = -2x + 27

Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions.
x= 90° - 63° = 27° (NO perpendicular to AOB)

= 180° - 128°
= 52°
y= 180° - x - 63° - angle DOB (angles on a straight line)

An angle measures 98° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Let the supplement = x
x + x +98 = 180 Equation
2x + 98 = 180 Subtract 98
2x = 180 - 98 Combine
2x = 82 Divide by 2
x = 82/2
x = 41
The two angles are
41
41 + 98 = 139
