The equation representing the right table is
.
The solution to the system of equations is
Answers
Answer:
The equation representing the left table is:
y = 1.5x – 6
The equation representing the right table is:
y = –4x + 6.1
The solution to the system of equations is:
(2.2, –2.7)
Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The first table is
x y
0 -6
1 -4.5
2 -3
3 -1.5
Slope = -4.5+6/1
=1.5
Now let us find y intercept
-6=1.5(0)+b
-6=b
So the equation representing the left table is y=1.5x-6
Now let us find second table
x y
0 6.1
1 2.1
2 -1.9
3 -5.9
m=2.1-6.1/1=-4
Now y intercept
2.1=-4+b
b=2.1+4
b=6.1
Equation representing the right table is y=-4x+6.1
Now equate two equations
1.5x-6=-4x+6.1
1.5x+4x=6.1+6
5.5x=12.1
x=12.1/5.5
x=2.2
and y=-4(2.2)+6.1
y=-8.8+6.1
y=-2.7
Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Cedro bought 10 ounces of Cereal A for $2.25. Then he bought 15 ounces of Cereal B for $3.30. Which cereal is less expensive?
Answers
Answer:
Cereal B.
Step-by-step explanation:
To figure out how much it costs per ounce for each cereal, first we need to divide.
Cereal A: $2.25 / 10 = $.225 per ounce
Cereal B: $3.30 / 15 = $.22 per ounce
So, cereal B is less expensive.

Which table represents a quadratic function?
Answers
Answer:
D
Step-by-step explanation:
A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.
And since we know the coordinated located on the line, we can fill out the formula for poiny-slope form:

Morgan is reading a 326-page book. The table shows three different plans to finish the book.
Plan Pages to Read Each Day Number of Days Needed
A 10 33
B 20 ?
C 30 11
Part A
Using Plan B, how many days will it take Morgan to finish her book? Enter your answer in the box.
days
Part B
Which explains how to find the number of days it will take Morgan to finish her book using Plan B?
Select all that apply.
A.
Multiply 20 × 16 to get 320, which is not enough days. So multiply 20 × 17 to get 340, which is enough days.
B.
Since 20 pages is halfway between 10 and 30 pages, the number of days must be halfway between 33 and 11 days.
C.
Since 10 pages are added each day from Plan A to Plan B, 10 days must be subtracted from the number of days needed in Plan A.
D.
Divide 326 ÷ 20 to get 16 R6. Round the quotient to the next greater whole number.
E.
Divide 326 ÷ 20 to get 17 R6. Round the quotient to the next greater whole number.

Step-by-step explanation:
Giveb that :
Area = 40cm²
Height, h = 12 cm
The volume of a prism is the product of it's base area and height, h
Base area = 40cm² ; height = 12cm
Volume = base area * height
Volume = 40cm² * 12cm
Volume = 480cm³

Answers
Answer and Step-by-step explanation:
We are given:
[tex]\frac{2y-1}{-3} = 5[/tex]
First, we multiply both sides by -3.
2y - 1 = 15
Now we add 1 to both sides.
2y = 16
Finally, we divide by 2 to each side.
y = 8
We are given:
2x + 30 = -4(5x -2)
First we distribute the -4 to 5x and -2.
2x + 30 = -20x + 8
Now we subtract 8 from both sides.
2x + 22 = -20x
Now we subtract 2x from both sides.
22 = -22x
Finally, we divide by -22 to both sides.
-1 = x
Statements: Reasons:
Given
2y - 1 = 15 Multiplication Property of Equality
2y = 16 Addition like terms
y = 8 Division Property of Equality
Statements: Reasons:
2x + 30 = -4(5x -2) Given
2x + 30 = -20x + 8 Distribution Property of Equality
2x + 22 = -20x Subtraction Property of Equality
22 = -22x Subtraction Property of Equality
-1 = x Division Property of Equality
