Step-by-step explanation:
Multiply each term inside the ( ) by the 5 outside the ( ).
5 x 2a = 10a
5 x -6b = -30b
5 x 8 = 40
Add the terms together (don't forget that it's negative 30b)
10a + -30b + 40 = 10a - 30b + 40

5 and2/3 divide by 4?
Answers
Answer:
The answer is 1 5/12 or 17/12.
Step-by-step explanation:
First we turn 5 2/3 into a Improper fraction.
5 2/3 = 17/3
Next we change 4 to 1/4 then multiply 1/4 by 17/3.
17/3 * 1/4 = 17/12
17/12 = 1 5/12
Hope this helps! :)

5[tex]\frac{2}{3}[/tex] / 4 = [tex]\frac{17}{3}[/tex] / [tex]\frac{4}{1}[/tex] = [tex]\frac{17}{3}[/tex] * [tex]\frac{1}{4}[/tex] = 17/12

So, basically I can't remember how to do this the long way but I used a calculator on Desmos (the graphing one to be specific). You should be able to find tutorials on how to use it and graph problems to find their answers but if not, you can just message me and I'll walk you through how to use it.
As for the form it asked for in the question, slope-intercept form is just:

m is the slope, and b is the y-intercept (the place where the line crosses the y-axis)

y when x = 25
Please help
Answers
Answer:
y = 20
Step-by-step explanation:
Given y is directly proportional to [tex]\sqrt{x}[/tex] , then the equation relating them is
y = k[tex]\sqrt{x}[/tex] ← k is the constant of proportion
To find k use the condition y = 32 when x = 64, then
32 = k[tex]\sqrt{64}[/tex] = 8k ( divide both sides by 8 )
4 = k
y = 4[tex]\sqrt{x}[/tex] ← equation of proportion
When x = 25, then
y = 4[tex]\sqrt{25}[/tex] = 4 × 5 = 20

Actually Welcome to the Concept of the exponents and indices.
here, we should remember one thing that,
3 ^3 = 27 and 1/3^x = 3^-x
so we get as,
(3^-3)^4-x = (3^3)^2x-1
==> 3^-12+3x = 3^6x-3
since the base is same that is 3 , we equate their powers.
-12x+3=6x-3
==> 3+3 = 6x+12x
==> 6 = 18x
hence ===> x = 6/18 = 1/3
hence, x = 1/3
Plentiful Pies determines its annual profits
in dollars using p(x) = 65x - 0.3x2 where x
represents the numbers of pies sold. If Plentiful
Pies sells 175 pies in a year, what will their
annual profits be?
Answers
Answer:
The annual profits will be 2187.5
Step-by-step explanation:
p(x) = 65x - 0.3x^2
I am guessing that the 2 was supposed to be a square.
Simply plug in the number of pies sold:
p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5

The perimeter of a triangle is 26 feet. The second side is twice as long as the first. the third side is 1 foot longer than the second side. What is the length of the 3 sides?
Answers
Answer:
5, 10 and 11 feet.
Step-by-step explanation:
Let length of first side be x feet then
second side = 2x feet
third side = 2x + 1 feet.
So we have the equation:
x + 2x + 2x + 1 = 26
5x + 1 = 26
5x = 25
x = 5 feet.
So first side = = 5 feet, second = 10 and third = 11 feet.

A Purse cost $75.00 at Macy’s with a 25% discount. What is the sale price with 7% tax?
Answers
Answer: $60.1875
Step-by-step explanation:
Since we are told that a purse cost $75.00 at Macy’s with a 25% discount. The sale price will be:
= $75 - (25% × $75)
= $75 - (0.25 × $75)
= $75 - $18.75
= $56.25
We will then add the 7% tax and this will be:
= $56.25 + (7% × $56.25)
= $56.25 + (0.07 × $56.25)
= $56.25 + $3.9375
= $60.1875
