Answer:
[tex](f+g)(x)=x^2-x-3[/tex]
Step-by-step explanation:
We have [tex]f(x)=2x-1[/tex] and [tex]g(x)=x^2-3x-2[/tex]
Recall that [tex]f+g[/tex] is defined by [tex](f+g)(x)=f(x)+g(x)[/tex], therefore
[tex](f+g)(x)=f(x)+g(x)=2x-1+x^2-3x-2=x^2-x-3[/tex]

Rewrite the following without an exponent (5/4)^2
PLEASE HELPP!
Answer:
16/25
Step-by-step explanation:
(5/4)^-2 = (4/5)^2 = 16/25
The given expression (5/4)⁻² is equivalent to 16/25.
To rewrite (5/4)⁻² without an exponent, we can apply the reciprocal property of exponents.
The reciprocal of (5/4)⁻² is equal to the reciprocal of 5/4 raised to the power of 2.
The reciprocal of a fraction is obtained by flipping the numerator and denominator.
So, the reciprocal of 5/4 is 4/5.
Now, we raise the reciprocal (4/5) to the power of 2.
To do this, we multiply the numerator and denominator of 4/5 by itself.
(4/5)² = (44) / (55) = 16/25
Therefore, (5/4)⁻² can be rewritten as 16/25 without an exponent.

Answer:
A: y = 17x
Step-by-step explanation:
Answer:
21 is A
22 is B
Step-by-step explanation:
51 / 3 = 17, which is the cost of 1 hour. That means, in order to find the charge (y), you need to multiply the # of hours (x) by 17. Equation A represents this correctly.
Now that we know this, for question 22, if someone rented a machine for 3.5 hours, to find the charge, multiply 3.5 by 17. This gives you 59.50.

The number of sweets s that each friend gets is the
number of sweets in a box n divided by the number of
friends f the sweets are shared between. Enter a formula
for the number of sweets each friend gets and enter the
number of sweets each friend gets if there are 54 sweets
and 6 friends.
Answer: 9 sweets/friend
Step-by-step explanation:
s = Number of sweets per friend
n = Number of sweets in a box = 54
f = Number of friends = 6
formula for the number of sweets each friend gets is as follows:
n/f = s
Therefore substituting in formula for n=54 and f=6
54/6 = 9 sweets per friend

Find AC someone help please. If you can please include steps
Answer:
AC = 15
Step-by-step explanation:
AC is the entire line split into two segments; AB and BC
We are given that AB = 8 and BC = 2x + 25 so we can combine these two and set them equal to AC ( = x + 24)
x + 24 = 8 + 2x + 25
Combine like terms and isolate x
x + 24 = 2x + 33
-9 = x
Now plug in -9 for x in the equation for line AC
(-9) + 24 = 15
Which set of ordered pairs represents a function?
{(5, -8), (8,-1), (8,7), (-4,2)}
{(-9,-9), (7, -9), (-7, -7), (9,-8)}
{(4,7), (-7,-4), (6,8), (-7,6)}
{(0,8), (-7,2), (4, -9), (4, -3)}

What is the slope of a line parallel to a line with equation -4y + 7x = 20?
Answer:
[tex]{ \underline{ \sf{slope \: is \: \frac{7}{4} }}}[/tex]
Step-by-step explanation:
Parallel lines have same slopes.
General equation of line:
[tex]y = mx + c[/tex]
the line given:
[tex] - 4y + 7x = 20 \\ 4y = 7x - 20 \\ y = \frac{7}{4} x - 5[/tex]

I’m crying rn I need helppp (number 4 ignore the rest) -1/2 to be left alone like without the x and what happened to the 5/2??
Step-by-step explanation:
The parallel line will have an equation of the form
[tex]y = -\dfrac{1}{2}x + b[/tex]
We solve for b by plugging in the values of the point (3, -4):
[tex]-4 = -\dfrac{1}{2}(3) + b[/tex]
[tex]\Rightarrow -8 = -3 + 2b[/tex]
Solving for b, we get
[tex]b = -\dfrac{5}{2}[/tex]
Therefore, the equation of the line parallel to 2x + 4y = 10 is
[tex]y = -\dfrac{1}{2}x -\dfrac{5}{2}[/tex]
In standard form we can write
[tex]x + 2y = -5[/tex] or [tex]2x + 4y = -10[/tex]

Answer:
D. 28
PEMDAS:
Parenthesis, exponents, multiplication, division, addition, subtraction
10 + (8 - 2)^2 / 2
1. Parenthesis comes first so we're left with
10 + (6)^2 / 2
2. Then we do the exponents
10 + 36 / 2
3. Then it's division
10 + 18
4. Finally we add
