Write the equation of a line through (2,4) and (-6, 8) in any form.
Answer:
Step-by-step explanation:
y=mx+c.... first find m(gradient/slope)
m=Y2-Y1/X2-X1
m=8-4/-6-2
m=4/-8
m=-1/2
Then find c
Take any point and fix in x and y
4=-1/2(2) +c
4=-1 +c
c=4+1=5
Therefore y=-1/2x+5
y+1/2x-5=0

Kiara made the table below to show the IQ scores and grade point averages (GPAs) of students in her class. She made another table to show the standardized test scores and IQ scores.
IQ, GPA, and SAT Scores

She graphs the data in each table and writes the rounded values as shown for the regression line y = a x + b.
I Q and G P A. a = 0.04. b = negative 0.9. I Q and Standardized Scores. A = 20. b = negative 924.
Next, Kiara uses the steps below to predict a student’s standardized test score based on the student’s GPA of 4.0.
Step 1 Write the equation of the trend line for IQ and GPA.
y = 0.04 x minus 0.9
Step 2 Write the equation of the trend line for IQ and standardized test score.
y = 20 x minus 924
Step 3 Find the IQ that is expected from a GPA of 4.0.
y = 0.04 x minus 0.9. 4 = 0.04 x minus 0.9. 4.9 = 0.04 x. 122.5 = x.
The IQ is about 122.5.
Step 4 Find the corresponding standardized test score for an IQ of 122.5.
122.5 = 20 x minus 924. 122.5 = 20 x minus 924. y = 523.
The standardized test score is 523.

A single card is drawn at random from a standard 52 card deck.
Work out the following probabilities in their simplest form:
P(Spade)
=
P(not Spade)
=
Answer:
1/4 - spade
3/4 - not spade
Step-by-step explanation:
There is 13 spades in a deck of 52 cards, so the probability would be 13/52, simplified to 1/4
4/4 - 1/4 = 3/4

Matthew and Mark were selling cups of lemonade. Matthew sold 15 more cups of lemonade than Mark. Together they sold 81 cups. How many cups did Matthew sell?
Answer:
48 cups
Step-by-step explanation:
Matthew and Mark were selling cups of lemonade.
Let the number of cups that Matthew sold = x
The number of cups Mark sold = y
Together they sold 81 cups.
= x + y = 81 cups...... Equation 1
Matthew sold 15 more cups of lemonade than Mark.
x = y + 15 cups
Substituting y + 15 for x in Equation 1
y + 15 + y = 81 cups
2y +15 = 81 cups
2y = 81 -15
2y = 66 cups
y = 66 cups/2
y = 33 cups
Hence, the number of cups Mark sold = 33 cups.
The number of cups Matthew sold is calculated as:
= x = y + 15 cups
x = 33 cups + 15 cups
x = 48 cups

HELP ASAP
Answer:
The value of x will be:
[tex]x=-5[/tex]Step-by-step explanation:
Given the equation
[tex]4-2(x+7)=3(x+5)[/tex]
Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.
[tex]4-2x-14=3x+15[/tex]
simplifying the equation by subtracting 14 from the L.H.S
[tex]-10-2x=3x+15[/tex]
Subtracting 15 from both sides
[tex]-10-2x-15=3x+15-15[/tex]
[tex]-25-2x=3x[/tex]
combining the like terms
[tex]-25=3x+2x[/tex]
[tex]-25=5x[/tex]
dividing both sides of the equation by 5
[tex]\frac{-25}{5}\:=\:\frac{5x}{5}[/tex]
[tex]-5=x[/tex]
Therefore, the value of x will be:

Identify the error in this column:
(x2 + 3x + 18) = (x + 3)(x + 6)
Answer:
I think the error is that the variable x came before the whole number 2.
[tex]x^2+3x+18 = (x+3)(x+6)[/tex]
↝ The error here is that (x+3)(x+6) doesn't make 3x in the middle here.
↝ From (x+a)(x+b) = x²+bx+ax+ab = x²+(a+b)x+ab
Now we let a = 3 and b = 6
Let's check the answer.
Given a = 3 and b = 6 (From the polynomials given.)
(x+a)(x+b) = x²+(a+b)x+ab
(x+3)(x+6)=x²+(3+6)x+(3*6)
(x+3)(x+6)=x²+9x+18
As you can see that the error here is that (x+3)(x+6) doesn't make 3x in the middle of polynomial. Therefore the error here is only 3x as proven.

Determine the slope of the line that passes through these points (3,9) and (-7,11)

-5
Step-by-step explanation:
To calculate the gradient of the slope, we have to calculate the [tex]\frac{rise}{run}[/tex].
[tex]\frac{3-(-7)}{9-11}[/tex] = [tex]\frac{3+7}{-2}[/tex]
[tex]\frac{3+7}{-2}[/tex] = [tex]\frac{10}{-2}[/tex]

The formula for the area A of a rectangle with a length of 5 inches is A = 5w, where w is the
width in inches. Make a table showing the area of the rectangles with a 5-inch length and a
width of 2, 4, 6, and 8 inches. What would be the ordered pairs on the table.
Answer:
Width 2 4 6 8
Area 10 20 30 40
Step-by-step explanation:
Area of a rectangle = length × width
Calculate width when length = 5 inches
When length = 5 inches and width = 2 inches
Area of a rectangle = length × width
A = 5 × 2
= 10 square inches
When length = 5 inches and width = 4 inches
Area of a rectangle = length × width
A = 5 × 4
= 20 square inches
When length = 5 inches and width = 6 inches
Area of a rectangle = length × width
A = 5 × 6
= 30 square inches
When length = 5 inches and width = 8 inches
Area of a rectangle = length × width
A = 5 × 8
= 40 square inches
Given the same length and different width
Width 2 4 6 8
Area 10 20 30 40
