Answer:

B)-7x+y=61

Step-by-step explanation:

y + 5 = 7(x– 8)

y + 5 =(7xX)(7x-8)

y + 5 =(7x)(-56)

y – 5 =(7x)(-56+-5)

y=7x-7x-61/

-7x+y=-61

Answer:

answer is below

Step-by-step explanation:

The question is not very clear but i would try to answer it

Given that

The constant of proportionality is the ratio between quantities that are directly proportional to each other. In this case, the constant of proportionality is the ratio of y to x.

Therefore the constant of proportionality is 1/2

A) For 6y = 3x

Dividing through by 6x gives:

They have the same constant of proportionality

measure angle D = 62

Step-by-step explanation:

as the sum  of measures of triangle =180

then (8x-40)+(4x-10)+(3x+20)=180

Answer:

y=2/7x-4

Step-by-step explanation:

Write in Slope intercept form

y=mx+b

m = slope

b = y intercept

x = x intercept

y = (0,-4)

So,

y = 2/7x+(-4)   substitute

y = 2/7x-4

Answer: The answer is: 83°

Step-by-step explanation

Here,

the sum of the total internal angle of a triangle is equal to 180°.

So,

8x+12+10x+23+55-3x=180

solving this equation we get, x=6°

finally,

the angle at George's position=10x+23=10*6+23=83°

Answer:

x = -6

Step-by-step explanation:

The triangle in the picture is an isoceles triangle in which the measure of top vertex angle is given and one of the base angles is also given.

According to angle sum property of triangle , sum of measure of all the angles of traingle is 180°. Also, in isosceles triangle , the base angles are always equal to each other .

So,

[tex]34 + (x + 79) + (x + 79) = 180[/tex]

[tex] = > 2x + 158 + 34 = 180[/tex]

[tex] = > 2x +192 = 180[/tex]

[tex] = > 2x = 18 0 - 192 = - 12[/tex]

[tex] = > x = \frac{12}{ - 2} = - 6[/tex]

Answer:

A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable

You can find the rate of change by using this formula:

[tex]m=(y_2 - y_1)/x_2 -x_1[/tex]

That m would go into another formula known as slope-intercept form

The equation is

y = mx +b

m = rate of change (or) slope

b = y-int

Step-by-step explanation: In its easiest form, an A=4, B=3, C=2, D=1, F=0.

If the class is 2 credit.......Multiply each numeric grade value by the number of credits the course was worth

Add these numbers together

Divide 45 by the total number of credits you took, in this example,13.

Your Weighted by Credit Hour GPA = 3.46

It depends on your school. Sorry this was not the most clear, I was taught like 2 years ago, and now I kinda forgot but hopefully this helps a lil dont get mad :)

Answer:

(x - 1, y + 1 )

Step-by-step explanation:

Consider the reflection in the y- axis

A point (x, y ) → (- x, y )

Consider the reflection of point A

A(- 5, 2 ) → A'(5, 2 )

Now A → E after the transformations

E = (4, 3 ), thus

A'(5, 2 ) → E(4, 3 )

(x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )

The translation rule is (x, y ) → (x - 1, y + 1 ).

In mathematics, translation is a transformation that moves every point of a figure or a graph the same distance and in the same direction. The object being translated retains its size and shape, but its position changes.

Consider the reflection in the y- axis

A point (x, y ) → (- x, y )

Consider the reflection of point A

A(- 5, 2 ) → A'(5, 2 )

Now A → E after the transformations

E = (4, 3 ), then

A'(5, 2 ) → E(4, 3 )

Thus, the translation rule is (x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )

Answer:

$162.50 per month for the next 4 years

Step-by-step explanation:

Here are the options to this question :

Save $270.83 per month for the next 4 years

Save $162.50 per month for the next 4 years

Save $650.00 per month for the next 4 years

Save $108.33 per month for the next 4 years

If Devon's parents would give him $5,200 for his first year of tuition, Devon needs to save a minimum of :

$13,000 - $5,200 = $7,800

If he saves per month for the next four months, he would save 48 times ( 12 months in a year multiplied by 4 years)

The minimum he should save per month = $7800 / 48 = $162.50

Answer:

The different ways a football team cold score 63 points are by having;

1) 3 touchdowns and 14 field goals

2) 6 touchdowns and 7 field goals

Step-by-step explanation:

The given parameters are;

The worth of each touchdown = 7 point

The worth of each field goal = 3 points

The number of touch down ≥ 1

The number of field goals ≥ 1

Let x represent the number of touchdowns and let y represent the number of field goals, we have;

7·x + 3·y = 63...(1)

x + y ≥ 2...(1)

Making y the subject of the equation, 7·x + 3·y = 63, gives;

3·y = 63 - 7·x

y = 21 - (7/3)·x

Making y the subject of the inequality, x + y ≥ 2, gives;

y ≥ 2 - x

From the attached graph created with Microsoft Excel, we have the points where x ≥ 1, that have a whole number value of y ≥ 0 as follows;

1) When x = 3, y = 14 gives 7×3 + 3×14 = 63

2) When x = 6, y = 7 gives 7×6 + 3×7 = 63

Therefore, the different ways a football team cold score 63 points are;

1) 3 touchdowns and 14 field goals

2) 6 touchdowns and 7 field goals.

Answer:

63 points

1) 3 touchdowns and 14 field goals

2) 6 touchdowns and 7 field goals
