Answer:

All real numbers.

Factors:

Answer:

m = -1/2 b = 4, equation = y = -1/2x + 4, Proportional, Negative slope

Step-by-step explanation:

To find m, see what slope is:

Is negative

for every one to right, goes down 1/2

so -1/2

Intercepts at 4, so b = 4

Step-by-step explanation:

Answer:

-22

Step-by-step explanation:

First, you must find the values for f(-8) and g(2).  f(x) is the blue line so f(-8)=-2 because that is the value of y where x=-8.  g(x) is the pink dotted line so g(2)=-4 because that is the value of y where x=2.  Then, plug in and solve:

-3(-2)+7(-4)

6+-28

6-28

-22

Answer:

Step-by-step explanation:

3x + 3y = -3 ------------(I)

-3x + 2y = 8 -----------(II)

Add both the equations and x will be cancelled and we can find the value of y

(I)          3x + 3y = -3

(II)       -3x  + 2y = 8     {Now add}

                    5y = 5

                      y = 5/5

y = 1

Now, substitute y = 1 in any of the equations. We are going to substitute in equation (I)

3x + 3*1 = -3

3x + 3 = -3

     3x = -3 - 3

     3x = -6

       x = -6/3

x = -2

The solution of the equation is the point of intersection.

Point of intersection = ( -2, 1)

[tex] - 3 + 2y = 8[/tex]

[tex]2y = 8 + 3[/tex]

[tex]2y = 11[/tex]

[tex]y = \frac{11}{2} [/tex]

[tex]3x + 3( \frac{11}{2} ) = - 3[/tex]

Step-by-step explanation:

Are you asking for the formula of a line that passes through these points?

=================================================

Explanation:

Check out the diagram below.

Plot R(-3,7) and T(3,-11) on the same xy grid.

Draw a vertical line through R and a horizontal line through T. A right triangle forms. At the intersection point is point S(-3,-11)

----------------------

Now measure the distance from point S to point T. You can count out the spaces or subtract the x coordinates and use absolute value.

|x1-x2| = |-3-3| = |-6| = 6

From point S to point T is 6 units.

We want to subdivide this horizontal length in the ratio 1:2

What this means is that we want to plot a point U somewhere such that SU:UT = 1:2

In other words,

SU = x

UT = 2x

SU+UT = ST

x+2x = 6

3x = 6

x = 6/3

x = 2

So we must move 2 spaces to the right from point S to get to U(-1,-11)

Going from point U(-1,-11) to T(3,-11) is 4 spaces

We have SU:UT = 2:4 = 1:2 to help confirm we have the correct location for point U

From point U, we then move straight up to the line segment RT

We'll land on Q(-1,1)

----------------------

Another way to find the y coordinate of point Q is to subdivide the segment RS into the ratio 1:2 similar to how we divided ST up

Segment RS is 18 units long since we go from y = 7 to y = -11 when going from R to S.

If V was on segment RS such that

RV:VS = 1:2

and RV = y

then

RV+VS = RS

y+2y = 18

3y = 18

y = 6

RV = y = 6

VS = 2y = 2*6 = 12

So you'll move 6 units down from y = 7 to land on y = 1 (when going from the y coordinate of R to the y coordinate of Q)

Answer:

  99 minutes

Step-by-step explanation:

Let the variable x represent the longer part of the movie. Then the shorter part is (x-11) and the total length is the sum of the parts:

  187 = x +(x -11)

  198 = 2x

  x = 99

The length of Part 2 is 99 minutes.

Answer: B

Step-by-step explanation:

Use the Pythagorean theorem; let the legs of the right trangle, a = 4 and b = 7:

c²=a²+b²

c²=4²+7²

c²=16+49

c²=65

c=√65 or c = 8.06

Therefore, B is the correct answer

Answer:

slope= 2 I case you need that :)

Answer:

Below.

Step-by-step explanation:

One way is to plot some points:

When x = 0, y = 2(0) - 4 = 4  So plot (0,-4).

In a similar way you can plot  when x = 1, y = 2(1) - 4 = -2 that is (1, -2).

Also 2(3) - 4 giving the point (3, 2).

Now draw a line passing through these 3 points.

If you cant draw a line through these points then Ive made a mistake in the calculations

The equation of the quadratic function represented by given table is f(x) = -0.25x² -x + 3.

Given table is:

x        y

-3       3.75

-2         4

-1        3.75

0         3

1         1.75

Let us say the quadratic function is:

f(x) = ax² +bx + c

A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are non-zero.

When, x=0, f(x) =3

So, 3 = c

So, f(x) = ax² +bx +3

When, x=1, f(x) =1.75

1.75 = a+b+3

a+b = -1.25........(1)

When, x=-1, f(x) =3.75

3.75 = a-b+3

a-b = 0.75........(2)

Solving equations (1) and (2)

a = -0.25

b = -1

So quadratic function will be:

f(x) = -0.25x² -x + 3

Therefore, the equation of the quadratic function represented by given table is f(x) = -0.25x² -x + 3.

===========================================================

Explanation:

Any rhombus is a parallelogram, but not the other way around.

For any parallelogram, the opposite angles are congruent.

-8y-8 = 88

-8y = 88+8

-8y = 96

y = 96/(-8)

y = -12

Also, for any parallelogram, the adjacent angles are supplementary (meaning they add to 180).

(-3x+8) + (88) = 180

-3x+96 = 180

-3x = 180-96

-3x = 84

x = 84/(-3)

x = -28

And we can also say,

88 + (-9z-7) = 180

-9z+81 = 180

-9z = 180-81

-9z = 99

z = 99/(-9)

z = -11
