Find the value of d so the line that passes through (a,b) and (c,d) has a slope of 12.
Answer:
d = 12c-12a+b
Step-by-step explanation:
The formula for calculating the slope of a line passing through two points (x1, y1) and (x2, y2)is expressed as:
m = y2-y1/x2-x1
Given the coordinates (a,b) and (c,d) and slope m = 12
Substitute into the formula as shown:
m = d-b/c-a
12 = d-b/c-a
Make d the subject of the formula:
12 = d-b/c-a
cross multiply
12(c-a) = d-b
12c-12a = d-b
add b to both sides
12c-12a + b = d-b+b
12c-12a + b = d
Hence d = 12c-12a+b

Explain how you used the distribute property to find an equivalent expression for
2 (3+8)
WORTH 10 POINTS
I need help with the first question
Answer:
Subtract 2k from both sides.
4k−3−2k=2k+5−2k
2k−3=5
Add 3 to both sides.
2k−3+3=5+3
2k=8
Divide both sides by 2.
2k /2 =8/2
k=4

A recipe that makes 16 cookies calls for 14 cup of sugar and 23 cup of flour. Janelle wants to proportionally increase these amounts to get a new recipe using one cup of sugar.
1. Using the new recipe, how much flour should she use? Explain or show your work.
16 cookies ¼ cup of sugar ⅔ cups of flour
??? 1 cup of sugar 2 ⅔ cups of flour
Answer:
64 cookies : 1 cup of sugar : 8/3 or 2 2/3 cup of flour
Step-by-step explanation:
16 cookies : 1/4 cup of sugar : 2/3 cup of flour
Multiply each part by 4 to find how much flour and how many cookies would be used in the same recipe with 1 cup of sugar.
64 cookies : 1 cup of sugar : 8/3 or 2 2/3 cup of flour

What is the equation in point slope form for a linear function with a slope of m=−4 that passes through the point (2,−7)?
Answer: y+7=-4(x-2)
Step-by-step explanation:
point slope formula is y-y1=m(x-x1)
it gives you m = -4
(x1,y1) = (-1,-7)
y-(-7) = -4(x-2)
negative of a negative number is positive
y+7=-4(x-2)
you leave that as your answer because thats what point slope for is
its in that form ^
The equation in point slope form for a linear function is [tex]y=4x+15[/tex]
Given the following points:
Points on the x-axis = 2 Points on the y-axis = -7 Slope, m = -4
To write an equation in point slope form for a linear function:
The standard form of an equation of line is given by the formula;
[tex]y-y_1=m(x-x_1)[/tex]
Where:
x and y are the points. m is the slope.Substituting the given parameters into the formula, we have;
[tex]y-(-7)=-4(x-2)\\\\y+7=4x-8\\\\y=4x-8+7\\\\y=4x+15[/tex]

-1 2/3 + (-2 1/6) A. Use the real number properties to write an equivalent expression for this sum.
B. Find the sum. Express your answer as a mixed number in lowest terms.
Answer:
-3 5/6
Here is what i did to solve it.:
-1 2/3 = -5/3, and -2 1/6 = -13/6. The LCD is 6.
We convert -5/3 to -10/6 and combine this result with -13/6:
-10/6 - 13/6 = -23/6
This last result can be rewritten as -3 5/6.
Hope this help, stay safe and have a nice day! :))))))

Three students were given the expression shown and were asked to take a
common factor out of two of the terms.
Use the drop-down menus to complete the statements about whether each
student's answer is an equivalent expression. Then choose an expression
that is equivalent
4 - 9x + 21
Step-by-step explanation:
The question is incomplete. Find the complete question attached.
Let us analyze each of the students expression and determine the correct one if there are any.
Chang expression after factoring: 4-3(3x+7)
In order to know whether chang's factorization is similar to the expression, we will expand and compare with the given expression as shown;
= 4-3(3x+7)
Open the parenthesis
= 4 - 3(3x)-3(7)
= 4 - 9x - 21
This shows that Chand expression is wrong.
Hence Chang expression is not an equivalent expression because when -3 is factored out from the bracket, it supposed to leave a negative sign instead of positive.
Benjamin expression after factoring: 4+3(3x+7)
In order to know whether Benjamin's factorization is similar to the expression, we will expand and compare with the given expression as shown;
= 4+3(3x+7)
Open the parenthesis
= 4 + 3(3x)+3(7)
= 4 +9x + 21
This shows that Benjamin expression is wrong.
Hence Benjamin expression is not an equivalent expression because the positive values within the expression is supposed to be negative sign instead
Habib expression after factoring: 4+12x
The equation is obviously wrong and not an equivalent expression because the constant value 21 does not have a variable x and cannot be added to -9x according to what Habib did.
Given the expression
4 - 9x + 21
The correct simplification of the expression is as shown;
4 - 3(3x - 7)
Note that when -3 is factored out, the sign inside the parenthesis also changes
