Step-by-step explanation:
f(x) = 2x² + 4x - 5
g(x) = 6x³ - 2x² + 3
(f-g)(x) = f(x) - g(x)
= (2x² + 4x - 5) - (6x³ - 2x² + 3)
= -6x³ + (2 + 2)x² + 4x + (-5 - 3)
= -6x³ + 4x² + 4x - 8

y = 2/5 x-3 in standard form fast please 30 points
Using the information given, write a linear equation in
slope-intercept form:
3.
1. slope = g y-intercept = -2
Help please
Step-by-step explanation:
The slope-intercept form is one way to write a linear equation (the equation of a line). The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It's usually easy to graph a line using y=mx+b. Other forms of linear equations are the standard form and the point-slope form.
Answer:
y = 9x - 2Step-by-step explanation:
Slope intercept form:
y = mx + b, where m- slope, b - y-interceptGiven:
m = 9, b = -2The equation of the line is:
y = 9x - 2Solve for x.
(6x + 4)º
5x
Answer:
x = 16
Step-by-step explanation:
6x + 4 and 5x are adjacent angles on a straight line and sum to 180° , that is
6x + 4 + 5x = 180
11x + 4 = 180 ( subtract 4 from both sides )
11x = 176 ( divide both sides by 11 )
x = 16

lesser x =
greater x =
Answer:
x = –9.41 or x = –6.59
Step-by-step explanation:
Hope it's help, study well goodluck
By solving the given Equation (x+8)² - 2 = 0 we get the Value from lesser x = -9.41 and greater x = -6.59
To solve the Equation (x+8)² - 2 = 0 and find the values of x,
Step 1: Expand the equation
(x+8)² - 2 = 0
(x+8)(x+8) - 2 = 0
(x² + 16x + 64) - 2 = 0
x² + 16x + 62 = 0
Step 2: Set the equation equal to zero and rearrange
x² + 16x + 62 = 0
Step 3: Use the quadratic formula
The quadratic formula states that for an equation in the form ax² + bx + c = 0, the solutions for x can be found using the formula:
x = (-b ± √(b² - 4ac)) / (2a)
In our equation, a = 1, b = 16, and c = 62.
Substituting these values into the quadratic formula, we get:
x = (-16 ± √(16² - 4(1)(62))) / (2(1))
x = (-16 ± √(256 - 248)) / 2
x = (-16 ± √8) / 2
Step 4: Simplify the square root
√8 can be simplified as follows:
√8 = √(4 × 2)
= √4 × √2
= 2√2
Substituting this into our equation:
x = (-16 ± 2√2) / 2
Step 5: Simplify further
We can simplify the expression by dividing both the numerator and denominator by 2:
x = -8 ± √2
So the solutions for x are -8 + √2 and -8 - √2.
Rounding to two decimal places, the solutions are approximately:
lesser x = -8 - √2 ≈ -9.41
greater x = -8 + √2 ≈ -6.59
Therefore, the solutions for x, from least to greatest (rounded to two decimal places), are -9.41 and -6.59.

A line passes through point. (6, -8) and has a slope of -3/2
Write an equation in Ax+By=C form for this line.
Answer:
3x + 2y = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{3}{2}[/tex] , then
y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
To find c substitute (6, - 8 ) into the partial equation
- 8 = - 9 + c ⇒ c = - 8 + 9 = 1
y = - [tex]\frac{3}{2}[/tex] x + 1 ( multiply through by 2 to clear the fraction )
2y = - 3x + 2 ( add 3x to both sides )
3x + 2y = 2 ← in standard form

Write an equation for each translation of y= | x |.
6.5 units up
A. y + 6.5 = | x |
B. y = | x | – 6.5
C. y = | x | + 6.5
D. y = | 6.5x |
Answer:
C. y = | x | + 6.5
Step-by-step explanation:
than you consider the x value zero and y equal zero so this mean the origin and from this the translation 6,5 units up will mean y = IxI +6,5
so the first choice is right sure
A. y = IxI +6,5
Answer:
A.
Step-by-step explanation:
We have been given an absolute value function . We are asked to translate the given function 6.5 units up.
Let us recall translation rules.
Using translation rules after translation our function would be .

Answer:
1. D. ) 5 1/4
2. C. ) 44/9
Step-by-step explanation:
Remember: A mixed number is a fraction and it's whole.
An improper fraction is when a numerator is more than it's denominator.
1. To find the mixed number we simply just need to ask ourselves, "how many times does the denominator go into the numerator?"
And we can see it goes in there only 5 times. So the entire fraction would be 5 5/20, in simplest form 5 5/20 is 5 1/4.
2. To express a mixed number into an improper fraction, we need to just multiply the whole number by the denominator.
So:
9 × 4 = 36
And then we add 36 to the numerator, which is 44, so our fraction is now 44/9, and it's already simplified.
Mrs. Huyhn bought a bag of three dozen toy animals as a party favor for her son's birthday party. The bag of toy animals cost 28.97 dollars. Estimate the price of each toy animal.
Answer:
Step-by-step explanation:
Answer:
$0.80
Step-by-step explanation:
first find out how many individual toys are in the bag. Since there are 3 dozen and we know that 1 dozen =12 items then we can multiply 12x 3=36 toys.
This means that he paid $28.97 for 36 toys. Now we need to find the cost of each toy by taking the amount he paid and dividing that by the number of toys. $28.97/36=0.80
