Use the distributive property to write an equivalent expression -3(-5x+7)
Answer:
15x - 21
Step-by-step explanation:
-3(-5x+7)
you sidtribute the 3 to both numbers by multiplying both the -5 and the 7 by -3
-3 x -5x = 15x (remember, a negative times a negative equals a positive)
-3 x 7 = -21 (A negative times a positive equals a negative)
15x - 21
I really need some help with this
Answer:
4
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 0, 4 ] , thus
f(b) = f(4) = - 4² + 8(4) - 4 = - 16 + 32 - 4 = 12
f(a) = f(0) = - 4 , then
average rate of change = [tex]\frac{12-(-4)}{4-0}[/tex] = [tex]\frac{12+4}{4}[/tex] = [tex]\frac{16}{4}[/tex] = 4

the area of an equilateral triangle is 16√3 cm2, then the perimeter of the triangle is?
Answer:
24 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ( s is the side length )
Here A = 16[tex]\sqrt{3}[/tex] , then equating gives
[tex]\frac{s^2\sqrt{3} }{4}[/tex] = 16[tex]\sqrt{3}[/tex] ( multiply both sides by 4 to clear the fraction )
s²[tex]\sqrt{3}[/tex] = 64[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
s² = 64 ( take square root of both sides )
s = [tex]\sqrt{64}[/tex] = 8
Thus
perimeter = 3 × 8 = 24 cm

how to you find the simplest interest
Answer:

Step-by-step explanation:
Simple Interest
Simple interest represents a fee you pay on a loan or income you earn on deposits.
When borrowing money: You must repay the amount you borrowed and make extra payments for interest, which represents the cost of borrowing.
When lending money: You typically set a rate and earn interest income in exchange for making your money available to other people.
When depositing money: Interest-bearing accounts such as savings accounts pay interest income because you are making money available to the bank to lend to others.
How to Calculate It
In the following example, the term "simple" means you're working with the simplest way of calculating interest. Once you understand how to calculate simple interest, you can move on to other calculations, such as annual percentage yield (APY), annual percentage rate (APR), and compound interest.

What is the y-intercept of the graph shown?
A)3
B)-5/2
C)1
D)5/2
Answer:
A
Step-by-step explanation:
A dot has a x - intercept and a y - intercept.
When looking for a y - intercept, you look at the y line in the graph. Where does the graph cross it?
The answer (in this case) is 3, because it's right in the middle between 2 and 4
What is the x-intercept of the slope of -2 and a y-intercept of 0, 6
Answer:
x- intercept = 3
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 = - 2 and c = 6 , thus
y = - 2x + 6 ← is the equation of the line
To find the x- intercept, let y = 0 in the equation and solve for x
- 2x + 6 = 0 ( subtract 6 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3 ← x- intercept or (3, 0 )
The highest yielding savings accounts are paying historically low

for her savings account. Assuming interest rates do not change,
use the Rule of 72 to approximate how many years it will take for
her to DOUBLE her money in this account? *
1 year
5 years
10 years
36 years
Answer:
36 years
Step-by-step explanation:
Maria interest rates was to get 2% annual. Her interest rate do not change of 72. So you will have to divide 72 out of 2 which that will give you 36 . 36 years is your answer.
Maria's money would double in 36 years
The rule of 72 is an heuristic that is used to determine in how many years it would take an investment to double given the interest rate
Rule of 72 = 72 / interest rate
72 / 2% = 36 years
Assume Maria has $10,000 in her account, it would take 36 years for the money to double.

Answer:
ans of problem 12 is:
x=65
y=10
Answer:
Step-by-step explanation:
Problem 12:
I think that (2x-y)+60=(2x+y)+40
Because of the Alternate Interior Angles theorem, which places the 40 next to (2x+y) so then you know they are a linear pair. Same can be done for the side with the 60 degree angle. So both sides add up to 180 so they are congruent themselves and you can put them in this format:
(2x-y)+60=(2x+y)+40
-40 -40
We do this to remove the 40 from the right side completely, and whatever you do to one side of the equation you have to do to the other as well so remove 40 from both.
(2x-y)+20=(2x+y)
-2x -2x
Again, we are just trying to find out y right now
-y +20=y
+y +y
20 = 2y
10 = y
Then insert the y into an equation telling us that it is equal to 180 (because we know that from before) to get what x is
(2x-y)+60=180
We can also input our y that we found out was 10 from before:
(2x-10)+60=180
And now we can add up 60 and -10
2x+50=180
Now subtract 50 to both sides
2x=130
And divide both sides by 2
x=75
So x=75 and y=10

At a certain college, the ratio to men to women is 5 to 4. If there are 2,800 men, how many women are there?
Answer:
2240
Step-by-step explanation:
braniest pls
there are 2,240 women at the college.
To find the number of women at the college, we can use the ratio of men to women given and the known number of men.
The ratio of men to women is 5 to 4, which can be expressed as 5/4.
If we know that there are 2,800 men, we can set up a proportion:
5/4 = 2,800/x
To solve for x, the number of women, we cross-multiply:
5x = 4 * 2,800
5x = 11,200
Dividing both sides by 5:
x = 11,200 / 5
x = 2,240
Therefore, there are 2,240 women at the college.

If 5/x = 15/x+20, what is the value of x/5?
Answer:
c) 2
Step-by-step explanation:
here you can use cross multiplication. that's where you turn the fraction into an equation. ( there's videos about it, I'm not very good at explaining )
so you can turn
[tex]\frac{5}{x} = \frac{15}{x + 20}[/tex]
into
5(x + 20) = 15x
5x + 100 = 15x
subtract 5x from both sides
100 = 10x
x = 10.
the value of x/5 would be 2, since 10/5 is 2.
Since x/5 is the reciprocal of 5/x, we know that we can flip the fraction on the right hand side will be flipped.
Thus, x/5 = (x + 20)/15
Now we cross multiply, 15x = 5(x + 20)
Simplify: 15x = 5x + 100
Subtract 5x from each side: 10x = 100
Divide 10: x = 10
Now plug 10 back into the right hand side: (10 + 20)/15
So, the answer is 2.
