solve for X
3x - 6 = 30

Answer:

In the graph of a circle, we can easily draw a straight vertical line passing through its center. This will hit the top and the bottom of the shape. Since this line hits two points, a circle's graph is not a function. We can also observe the equation of a circle.

Answer:

No

Step-by-step explanation:

Do a vertical line test.

First, put your pencil or ruler up against the screen.

Move it down the graph and if there are two points in one x point, it is not a function. For example, look at 0, 3 and 0, -2.5. They share the same x point.

Therefore, it is not a function.

The equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

This is the required equation of a line in a point-slope form.

We know that Point-Slope Form:

y - y₁ = m(x- x₁)  

Where x₁ - x coordinate and y₁ - y coordinate

m - slope

Point (8,-4)

Then Slope m = 1/2

Now the equation as;

y + 4 = 1/2(x - 8)

 y  = -1/2(x -4) - 4

y = -x/2 + 2 - 4

y = -x/2 - 2

Hence, the equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2

Answer:

  A.  {1, 7, 11}

Step-by-step explanation:

The constant in the equation is 1, so that is the value when x=0. No answer choice can be correct unless it includes the value 1. The only viable choice is A.

_____

If you want to go to the trouble to evaluate the expression for the different values of x, you can. It often works well to rewrite the expression to "Horner form":

  (2x -1)x +1

For x = -2, this is (2(-2) -1)(-2) +1 = (-5)(-2) +1 = 11

For x = 0, this is 1

For x = 2, this is (2(2) -1)(2) +1 = (3)(2) +1 = 7

So, the range for the given domain is {1, 7, 11} . . . . . matches choice A

Answer:

there are 8800 yards in 5 miles

Step-by-step explanation:

there are 1760 yards in a mile and multiply that by 5 to get 8800

its C because if you multiply 5280 by 5 is 26400 feet in 5 miles but we need yards so then we divide 26,400 by 3 witch is

Awnser: 8,800 yards or C

Answer:

Answer:

Step-by-step explanation:

All the numbers have to be multiplied by the same amount for it to be proportional

A proportional amount to 4:2:1:5 would be 12:6:3:15

They have all been multiplied by the same number 3

Answer:

Yes, the ratio is proportional

Step-by-step explanation:

given 4.2 : 1.5 =? 12.6 : 4.5 is it proportional

it must follow the means extremes property

[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex]

a*d = b*c, so let's plug in the values

[tex]\frac{4.2}{1.5}[/tex] =? [tex]\frac{12.4}{4.5}[/tex]

(4.2)*(4.5) =? (1.5)*(12.6)

18.9 = 18.9 which is true; therefore the ratio is proportional

Answer:a

Step-by-step explanation:

Step-by-step explanation:

8x + y = -16

y = -8x - 16 --(1)

-3x + y = -5 --(2)

sub (1) into (2):

-3x - 8x - 16 = -5

-11x = 11

x = -1

sub x = -1 into (1):

y = -8(-1) - 16

y = -8

therefore, the solution is (-1, -8).

Step-by-step explanation:

If the dots lead in a straight line starting from the axis the relationship is proportional

Answer:

m∠1=77°

m∠2=36°

m∠3=30°

Step-by-step explanation:

First, find angle 1 by adding 66 and 37 and subtracting them from 180 because there are 180 degrees in an angle.

180-(66+37)=77°

You can then find angle 2 by finding the other angle not given. You can find this angle by subtracting 77 from 180, giving you 103. To find angle 2, add 103 and 41 and subtract them from 180.

180-(103+41)=36°

You can then find angle 3 by adding the angle 103 and the angle 47, and subtracting them from 180

180-(103+47)=30°

Answer:

The answer is $90.
