Answer:
equation: y -1 = -4(x +1)y-intercept: -3slope-intercept equation: y = -4x -3Step-by-step explanation:
The slope of the line is found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (-11 -1)/(2 -(-1)) = -12/3 = -4
Then the point-slope form of the equation for a line can be used to write the equation:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
Using the first point, the equation is ...
y -1 = -4(x +1)
__
Simplifying to slope-intercept form, we can find the y-intercept.
y = -4x -4 +1
y = -4x -3 . . . . . . . . slope-intercept form
The constant in this equation is the y-intercept: -3, point (0, -3).

Dominic is asking his relatives and friends to contribute $2 each to the school library fund. So far he has collected donations from 23 of his relatives. The expression 2(f+23) represents the total amount of money Dominic expects to receive. What part of the expression represents the total number of people that Dominic expects to contribute $2 to his project?
A
f
B
23
C
f+23
D
2f+23
Answers
Answer:
Option C : f+23 is the correct answer.
Step-by-step explanation:
Given that:
Amount Dominic wants everyone to contribute = $2
Number of relatives who have contributed = 23
The expression is;
2(f+23)
As we know that 2 represents the amount and 23 represents the number of relatives who have donated, therefore,
f represents the number of people who would donate to the library fund, and
f+23 represents the total number of people who contributes to the fund.
Hence,
Option C : f+23 is the correct answer.

use distributive property to write an expression 0.4(-5-7y-13.8)
Answers
Answer: -2.8y - 7.52
The simplified form of the expression is -2.28y - 7.52.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is a number used before a phrase.
Given:
An expression,
0.4(-5-7y-13.8).
Solving the expression with the help of distributive property,
0.4 x -5 - 0.4 x 7y - (0.4 x 13.8).
= -2 -2.8y - 5.52
= -2.28y - 7.52
Therefore, -2.28y - 7.52 is the solution.

Answers
Answer:
1st Qtrl: 11
Median: 20.5
3rd Qtrl: 25.5
Range: 22
Step-by-step explanation:
Median = average of 2 middle values (18 + 23) / 2
1st Qtrl = average of 10 and 12 (the lower half of data)
3rd Qtrl = average of 25 and 26 (the upper half of data)
Range = largest value - smallest value; 30 - 8 = 22

I have been working all morning on this question and still I don't have the answer to it. What is 2 and 2/4 + 3 and 2/4?
Answers
Answer: 2 and 2/4 + 3 and 2/4 = 1.
Step-by-step explanation:
in these type of problems you need to add separately the whole and rational parts:
(2 and 2/4) + (3 and 2/4) = (2 + 3) and (2/4 + 2/4)
= 5 and 4/4
but 4/4 = 1
And also remember that the "and" is equivalent to a "+" sign, then:
5 and 4/4 = 5 + 1 = 6
Then:
2 and 2/4 + 3 and 2/4 = 1.

Karrem says that the ratio 4:1 is eqivilent to the ratio of 12:9 because 4+8=12 and 1+8 =9 is karreem correct
Answers
Answer:
No, Kareem is incorrect.
Step-by-step explanation:
Kareem says that the ratio of [tex]\frac{4}{1}=\frac{12}{9}[/tex] because 4 + 8 = 12 and 1 + 8 = 9
But the correct way to rewrite the ratio 4 : 1 is,
[tex]\frac{4}{1}=\frac{4\times 3}{1\times 3}[/tex]
Which becomes as,
[tex]\frac{4}{1}=\frac{12}{3}[/tex]
Therefore, Kareem is not correct.
Correct ratio equivalent to 4 : 1 is 12 : 3.
