Answer:

y = -7

Step-by-step explanation:

It has a slope of zero (it is just a straight,infinite line)

And it passes through the point (5,-7) because it is continuous and infinite

Answer:

9

Step-by-step explanation:

150/2 = 75

72/8=9

Answer:

v is 9 degrees

Step-by-step explanation:

The 2 angles are supplementary angles

Therefore,

8v + 3 + 105 = 180 (supplementary angles add up to 180 degress/straight line)

               8v = 180 - 105 - 3

               8v = 75 - 3

               8v = 72

                 v = 72/8

                 v = 9 degrees

Step-by-step explanation:

20x² = y - 24

y = 20x² + 24

For y to have the least possible value, x² have to be the least possible, which is 0.

Since -3 <= x <= 2 includes x = 0, this is allowed.

Hence least possible value of y

= 20(0)² + 24 = 24.

Answer:

24

Step-by-step explanation:

-3---> 20(-3)^2=y-24 ----> y=204

-2---> 20(-2)^2=y-24 ----> y=104

-1---> 20(-1)^2=y-24 ----> y=44

0---> 20(0)=y-24 ----> y=24

1---> 20(1)^2=y-24 ----> y=44

2---> 20(2)^2=y-24 ----> y=104

Step-by-step explanation:

A: pass (0,0) (12,6)

slope: 6/12 = 1/2

y = 1/2 x

x=1   y= 1/2

B: pass(0,0) (4,6)

slope: 6/4 = 3/2

y = 3/2 x

y=1  x= 2/3

Answer:

the new price of the t-shirt is $24.84

Step-by-step explanation:

The computation of the new price of the t-shirt is shown below

= Price of the t-shirt × (1 + increased percentage)

= $23 × (1 + 0.08)

= $23 × 1.08

= $24.84

Hence, the new price of the t-shirt is $24.84

We simply applied the above formula so that the correct value could come

And, the same is to be considered

Answer:

C

Step-by-step explanation:

Given y = f(x) then y = f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Thus (x - 5)² is a shift to the right of 5 units

Given y = f(x) then y = f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Thus

y = (x - 5)² + 6

is the graph of y = x² translated 6 units up and 5 units to the right → C

Answer:

60 Pages.

Step-by-step explanation:

Using the given information, we can figure out that the remaining 36 pages are 60% of the book.

This is because 100% (whole book) - 40% (what you already read)= 60%= the remaining 36 pages

We can set up a problem to find 36 pages out of how many total pages is equal to 60%

(36/x) x 100 = 60%

=3600/60

=60 pages.

We can check our work by saying checking that 40% of 60 is 24, and 24+36 is 60 pages.

Answer:

D

Step-by-step explanation:

Option D is the only equation where the y-term gets eliminated upon simplifying

11y + 17 = 5y - 10 + 6y

11y + 17 ≠ 11y - 10

the answer should be y

y would represent the output values.

What are different values in a linear equation of a straight line?

The equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y-intercept (the point in which the line crosses the y-axis).

y = mx + c is a linear equation and the variables x and y relate to coordinates on the line.

When we input a value for x into the equation y = mx + c, we get a result for y.

This means that x is an independent variable, and y is a dependent variable as it is determined by the value of x.

I assume you want to mathematically represent the above

Answer and explanation:

If Diego collected x kg of recycling and Lin collected 2/5 more than what Diego collected, then it would be represented mathematically thus:

Diego = x

Lin = x +2/5 of x= x+2/5x

if Lin biked x km and Diego biked 3/10km less than Lin, then we would represent this thus:

Lin=x

Diego= x-3/10 of x= x-3/10x

If Diego reads for x minutes and Lin reads 4/7 of what Diego read, then mathematically we represent this thus:

Diego=x

Lin =4/7 of x = 4/7x

Answer:

(5,-2)

Step-by-step explanation:

Midpoint formula

If we have coordinates (x₁,y₁) and (x₂,y₂), then the midpoint of these coordinates is determined by (x₁ + x₂)/2, (y₁ + y₂)/2. This forms a new coordinate you can call (x₃,y₃). The midpoint calculator will solve this instantaneously if you input the coordinates. Follow the steps above if calculating by hand.

For small numbers, it's easy to calculate the midpoint by hand, but with larger and decimal values, the calculator is the simplest and most convenient way to calculate the midpoint.

Answer:

Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.

An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs.
