Answer:
slope is -2
and y-intercept is 13
Step-by-step explanation:
[tex]slope=m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{5-3}{4-5}=\frac{2}{-1}\\slope=m= -2\\Then, we can write equation of line as y=mx+b\\y=-2x+b\\using either points given we can find b \\so using point (4,5)\\5=-2(4)+b\\so b=13\\ therefore y-intercept is = 13[/tex]

Answer:
24
Step-by-step explanation:
If f is equal to 7, you'd multiply 7 by 2 (following pemdas/gemdas). When you multiply those two numbers, you get 14. If you add 8 to 14 you get 24.
Find the value of c that completes the square
x^2-16x+c
Please help me with how to do this, and show me. Thank you.
Answer:
The value that completes the square is: c=8
Step-by-step explanation:
Find the value of c that completes the square [tex]x^2-16x+c[/tex]
The formula used is: [tex]a^2-2ab+b^2=(a-b)^2[/tex]
In the question given the value c can be found by breaking the middle term. we are given -16x while the general formula is 2ab for middle term so,
2(x)(8) = 16x
so, c= 8
Solving:
[tex]x^2-16x+c\\=x^2-2(x)(8)+(8)^2-(8)^2\\=(x-8)^2-64[/tex]
So, the value that completes the square is: c=8
Divide.
−36−8

4(2x - 1) + 3(2x+5)
Answer:
14x + 1
Step-by-step explanation:
4(2x-1)+3(2x+5) = 2x*4 - 1*4 + 2x*3 + 5*3
= 8x - 4 + 6x + 5
= 8x + 6x -4 + 5 {Combine like terms}

Given y = 9x - 4, what is the y-intercept?
a.) 4
b.) -4
c.) 9
Answer:
B.) -4
Step-by-step explanation:
y=mx+b
b is equal to the y-intercept.
Answer:
-4
Step-by-step explanation:
The slope intercept form is y = mx + b.
m = slope
b = y-intercept
since b = -4, the y-intercept is -4

-6a +3 =-3(2a-1) question number 2
Answer:
D. identity
Step-by-step explanation:
- 6a + 3 = - 3(2a - 1)
First, distribute -3 within the parenthesis.
- 6a + 3 = - 6a + 3
Subtract 3 from both sides of the equation
- 6a = - 6a
Divide - 6 on both sides of the equation
a = a
We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity
For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.
I hope that this helps! :)

What is the slope of the line that contains the points (-2, 2) and (3, 4)?
A.
O B. -
O c.
OD.
Answer: m = 2/5
Step-by-step explanation:
The formula for the slope is m = rise over run = y^2 - y^1 / x^2 - x^2
which makes it 4-2 over 3-(-2) which equals 2/5
Youre answer is 2/5
Answer:
The slope of the line that contains the points (-2, 2) and (3, 4) is 2/5.
Step-by-step explanation:
The slope of a line is denoted by m and is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here
[tex](x_1,y_1)[/tex] are the coordinates of the first point on line and
[tex](x_2,y_2)[/tex] are the coordinates of the second point on line
Given two points are:
(x1,y1) = (-2, 2)
(x2,y2) =(3, 4)
Putting the values in the formula
[tex]m = \frac{4-2}{3-(-2)}\\m = \frac{2}{3+2}\\m=\frac{2}{5}[/tex]
Hence,
The slope of the line that contains the points (-2, 2) and (3, 4) is 2/5.

A company announces that it will be giving $4,200 of its profits to charity. If the company profits 28,000 what percent will the company give to charity
Given:
Company profits = $28,000
Charity = $4200
To find:
The percent that will the company give to charity.
Solution:
We have,
Company profits = $28,000
Charity = $4200
Now,
[tex]Charity\%=\dfrac{Charity}{Profit}\times 100[/tex]
[tex]Charity\%=\dfrac{4200}{28000}\times 100[/tex]
[tex]Charity\%=\dfrac{420}{28}\times 1[/tex]
[tex]Charity\%=15\%[/tex]
Therefore, the company will give 15% of its profit to charity.

Answer:
the answer to your question is y = -30
Answer:
-30
-Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2y+5=-10
Step 2: Subtract 5 from both sides.
1/2y+5-5=-10-5
1/2y+-15
Step 3: Multiply both sides by 2.
2*(1/2y)=(2)*(-15)
y=-30
