Answer:
f(-2)=15
Step-by-step explanation:
To find f(-2), we want to find what f(x), or y is, when x is equal to -2.
f(x)= -5x+5
Therefore, we can substitute -2 in for x.
f(-2)= -5(-2)+5
Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Multiply -5 and -2
f(-2)=10+5
Add 10 and 5
f(-2)=15
Answer:
f(-2) = 15, or y = 15
Step-by-step explanation:
f(-2) = -5(-2) + 5
f(-2) = 10 + 5, a negative multiplied by a negative will be a positive !
f(-2) = 15
y = 15
(3x+20)=(5x-16) Find the value of X
Answer:
x = 18
Step-by-step explanation:
3x + 20 = 5x - 16
Subtract 20 from both sides
3x + 20 - 20 = 5x - 16 -20
3x = 5x -36 {Now subtract 5x from both sides}
3x - 5x = 5x - 36 +5x
-2x = -36 {Divide both sides by (-2)}
-2x/-2 = -36/-2
x = 18
Step-by-step explanation:
(3x+20)=(5x-16)
combination of like terms
3x-5x= -16-20
-2x= -36
x= -36/-2
x=18

If f(x)= 2x+3 and g(x)= 7x-9. What is f(x) + g(x)?
Answer:
9x -6
Step-by-step explanation:
f(x)= 2x+3 and g(x)= 7x-9
f(x) + g(x) = 2x+3 + 7x-9
Combine like terms
= 2x+7x +3-9
=9x -6
Answer:
9x-6

Answer: The package reaches the ground in
4.67 s
and hits the ground with a speed of
33.8 m/s
Answer:
3m/s or option 1
Step-by-step explanation:
Given,
Height(h)=90m
time(t)=30s
Speed(v)=?
Now,
Speed(v)=distance/time
v=height/time(Since,height here is the distance covered by the balloon)
v=90/30
v=3
Unit of speed is m/s
Therefore,v=3m/s

Kyleigh put a large rectangular sticker on her notebook.the height of the sticker measures 10 cm. the base is half as long as the height. what area of the notebook does the sticker cover?
Hey there! Welcome to Brainly! I'm happy to help you!
When we are talking about the height and base, let's use the variables h and b. With the information we have been given, we can make the following equations below.
h=10 (the height is 10)
b=h/2 (base is half as long as the height)
We see that h is equal to ten. b is equal to h divided by two, so it is therefore ten divided by 2! We take the value for h and the plug it into the second equation!
b=10/2
b=5
So, we now know that the height is 10 cm and that the base is 5 cm. However, we need to find the area. To find the area of a rectangle, we just multiply the base by the height!
10(5)=50
Therefore, the area of the sticker is 50 cm².
I hope that this helps! Have a wonderful day!
Which equation in point-slope form contains the points (0,5) and (5,8)?
A. y - 8 = (x - 5)
B. y - 5 = (x – 8)
c. y - 8 = {(x - 5)
D. y - 5 = (x – 8)
I'm going to assume you pasted the question and answers and the fractions for the slope didn't come up.
Solve for the slope using the given values.
Slope formula: y2-y1/x2-x1
= 8-5/5-0
= 3/5
Point slope form: y - y1 = m(x - x1)
Using the point (5, 8) and the slope (3/5), it should look like:
y - 8 = 3/5(x - 5)
Best of Luck!
Put in order rational numbers
Answer:
[tex]-\frac{26}{40}[/tex]
[tex]-\frac{9}{20}[/tex]
[tex]\frac{12}{25}[/tex]
Step-by-step explanation:
Divide each individually.
[tex]-\frac{9}{20}=-0.45[/tex]
[tex]\frac{12}{25}= 0.48[/tex]
[tex]-\frac{26}{40}=-0.65[/tex]
Since you have to order them from least to greatest, begin by the negative number that is farthest from 0. In this case, -0.65, the next negative number would be -0.45 and finally we only have one positive number 0.48
3) Which of the equivalent expressions for P(x) reveals the profit when the price is
zero without changing the form of the expression?
a) P(x) = -3x2 + 432x - 1680
b) P(x) = -3(x - 4)(x - 140)
c) P(x) = -3(x - 72)2 + 13872
4) Find the profit when the price is zero.
Question:
Which of the equivalent expressions for P(x) reveals the profit when the price is
zero without changing the form of the expression? P(x) = -3x² + 432x - 1680
a) P(x) = -3(x - 4)(x - 140)
b) P(x) = -3(x - 72)² + 13872
Find the profit when the price is zero
Answer:
- P(x) = -3(x - 140)(x - 4).
- P(0) = -1680
Step-by-step explanation:
Given
P(x) = -3x² + 432x - 1680
Required
- Find equivalent of P(x)
- Find P(x) when x = 0
To find the equivalent of P(x), we simply factorize P(x) = -3x² + 432x - 1680.
This is done as follows
P(x) = -3x² + 432x - 1680
P(x) = -3x² + 12x + 420x - 1680
P(x) = -3x(x - 4) + 420(x - 4)
P(x) = (-3x + 420)(x - 4)
Further expand -3x + 420
P(x) = -3(x - 140)(x - 4).
Hence, the equivalent of
P(x) = -3x² + 432x - 1680
without changing its form is
P(x) = -3(x - 140)(x - 4).
When price is 0, then x = 0.
Substitute 0 for P(x) in P(x) = -3(x - 140)(x - 4).
P(0) = -3(0 - 140)(0 - 4).
P(0) = -3(-140)(-4)
P(0) = -1680
Hence, the profit when price is 0 is -1680

If a polynomial function f(x) has roots 0, 3, and 2+ V5, what must also be a root of f(x)?
-2-sqrt15
2-sqrt15
15-sqrt 2
15+sqrt 2
Answer:
Option B.
Step-by-step explanation:
Note: Given roots are not in proper format.
Consider the polynomial function f(x) has roots 0, 3, and [tex]2+\sqrt{15}[/tex].
According to irrational root theorem if [tex]a+\sqrt{b}[/tex] is root of a polynomial P(x), then [tex]a-\sqrt{b}[/tex] is also a root of polynomial P(x).
Since [tex]2+\sqrt{15}[/tex] is an irrational root of the function f(x). By irrational root theorem [tex]2-\sqrt{15}[/tex] is also a root of function f(x).
Therefore, the correct option is B.
Answer:

Find the 100th term in the arithmetic sequence 0,5,10,15
Answer:
easy peasy,
the 'n' th term of any arithmetic sequence can be found with the following formula
=> a + ( n-1) d, [where 'a' if the first term of the sequence, 'n' the number of term we need to find, and 'd' being the common difference between each two consecutive term of the sequence)
all in this case would be,
a = 0
n = 100
d = +5
hence the 100th term would be,
=> 0 + (100 - 1) 5
=> 99 x 5
=> 495
What is the area of the triangle?
Answer: 24
Step-by-step explanation:
Area = 1/2 x base x height
Answer:
24cm²
Step-by-step explanation:
So you do 8×4=48 (a square) then half it (triangle) which becomes 24cm²
Well, a simple way to do it is to do base × height then half it

You decide to borrow money to pay for college at 22% interest per year, in 2023.
How much will you owe on a loan of $5,000 in 2027?
Answer: On loan of $5000 at that rate, you would be owing $9400
Step-by-step explanation: The loan is being borrowed at an interest rate that is calculated yearly. This is a case of a simple interest. The same amount of interest is calculated and that will be payable per year. The amount borrowed is the principal, and in this instance is $5000. The amount of interest payable is calculated as 22 percent of the principal and is paid yearly. So if a loan (principal amount) of $5000 is borrowed for a period of 4 years (that is, 2023 to 2027), then the interest is calculated for four years.
Hence, the formula for a simple interest computation is given as follows;
Interest = P x R x T
Where P = 5000, Rate = 0.22 (22 percent), and T = 4 (time in years)
Interest = 5000 x 0.22 x 4
Interest = 20000 x 0.22
Interest = 4400
Therefore, from the calculations shown, a loan of $5000 at the rate of 22% borrowed from 2023 to 2027 would have an interest payable of $4,400.
Upon repayment of the loan, you would be owing a total of $9,400 (that is, amount borrowed plus interest owing)
