I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS

Answer:

first answer is y = 2x + 2

second answer is y = 1/4x + 6

Step-by-step explanation:

sooo to find the slope you can just count it but i feel like using the equation

y2 - y1 / x2 - x1

is better

so lets substitute

6 - (-6) / 2 - (-4)

6 + 6 / 2 + 4

12 / 6

y = 2x + b

to find b we substitute a point we did not use yet (-2, -2)

-2 = 2(-2) + b

-2 = -4 + b

b = 2

y = 2x + 2

second question:

we do the same thing

(-4, 5) (8, 8)

8 - 5 / 8 - (-4)

3 / 12

1/ 4

y = 1/4x + b

since the graph shows the y intercept (0, 6) we can input it into the equation

y = 1/4x + 6

i cant check it (with a point) because there are not a lot of exact points, but this should be the answer

Answer:

11m + 3

Step-by-step explanation:

First you have to find the product of Mai's age and 11. You can do this by adding 11 as the coefficient to the variable m like 11m. Then you have to add 3 to that product, which you can do by adding 3 to it like 11m + 3. In the end, you have an expression that first multiplies Mai's age by 11 and then adds 3.

Answer:

x ≈ 28°

Step-by-step explanation:

We know the hypotenuse (the longest side) and the opposite (the side opposite x) so we can use SOH:

sine x = opposite ÷ hypotenuse

Substitute in the values:

sin x = 7 ÷ 15

sin x = 0.4666...

Now we can do the inverse of sine to find x:

x = [tex]sin^{-1}[/tex](0.466..)

x = 27.818138... ≈ 28°

Answer:

10

Step-by-step explanation:

say x=0

then y would be 1

increasing x by 5 makes x=5

and then 5 x 2 + 1=11

so y went from 1-11(difference of 10) with the variation

so the answer is 10

Answer:

=

Step-by-step explanation:

3 feet = 1 yard, so knowing this, if you divide 12 feet by 3, you get 4

Another way you could check this is if you multiply the 4 yards by 3 feet per yard. You would get 12 feet.

Either way you do it, they are equal

Answer:

=

Step-by-step explanation:

      I am going to assume that this question is asking us to compare the two measures of distance.

      To do this, we need to convert them into the same unit. I am going to convert 4 yards into feet and leave 12 ft as 12 feet.

4 yards * 3 feet in a yard = 12 feet

Using the reflexive property, 12 feet is equal to 12 feet, so '=' completes this question.

Answer:

Six visits

Solving steps:

Question:. Francisco has a points card for a movie theater. He receives 55 rewards points just for signing up. He earns 9.5 points for each visit to the movie theater. He needs 112 points for a free movie ticket. How many visits must Francisco make to earn a free movie ticket?

Find out: How many visits required for 112 points.

Solution: Let's make an equation

=> 55 + 9.5x = 112

Let's make x the subject of formula

=> 9.5x = 112 - 55

Substract 55 from 112

=> 9.5x = 57

Divide both sides by 9.5

=> [tex] \frac{9.5x}{9.5} = \frac{57}{9.5} [/tex]

Divide

=> x = 6

Therefore Francisco needs 6 visit to earn a free movie ticket

The number of visits Francisco must make to earn a free movie ticket is 6.

Given that, Francisco receives 55 rewards points just for signing up. He earns 9.5 points for each visit to the movie theater.

Let the number of visits to the movie theater be x.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

He needs 112 points for a free movie ticket.

Now, the equation is [tex]9.5x+55=112[/tex]

[tex]9.5x=112-55[/tex]

[tex]9.5x=57[/tex]

[tex]x=\frac{57}{9.5}[/tex]

[tex]x=6[/tex]

Therefore, the number of visits Francisco must make to earn a free movie ticket is 6.

Step-by-step explanation:

You divide 55 by 8% and you add 25%.

Answer:

(2, 3 )

Step-by-step explanation:

5x - 4y = - 2 → (1)

2x + 4y = 16 → (2)

add (1) and (2) term by term to eliminate y

7x + 0 = 14

7x = 14 ( divide both sides by 7 )

x = 2

substitute x = 2 into either of the 2 equations and solve for y

substituting into (2)

2(2) + 4y = 16

4 + 4y = 16 ( subtract 4 from both sides )

4y = 12 ( divide both sides by 4 )

y = 3

solution is (2, 3 )

Answer:

( 2 , 3 )

Step-by-step explanation:

5x - 4y = - 2 ⇒ ( 1 )

2x + 4y = 16 ⇒ ( 2 )

( 1 ) + ( 2 )

5x - 4y + 2x + 4y = -2 + 16

7x = 14

Divide both sides by 7.

x = 2

Now let us take equation (1) to find the value of y.

5x - 4y = - 2

5 × 2 - 4y = -2

10 - 4y = -2

-4y = - 2 - 10

-4y = - 12

Divide both sides by ( -4 )

y = 3

Answer: a rotation about point A

Step-by-step explanation:

The rigid transformation would map ΔAQR to ΔAKP is rotation about point A.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have to transform ΔAQR to ΔAKP.

We know that,

Point A is invariant, so we that it cannot be rotation about point R.

Also, the orientation is same then reflection is not happening here.

So, there is rotation about the point A.
