The value of the x-intercept is 6, the y-intercept is 75, and the value of the slope is -25/2.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The x-intercept from the graph(where y = 0)

The x-intercept = 6

The y-intercept from the graph(where x = 0)

The y-intercept = 75

The slope can be found using two points: (0, 75) and (2, 50)

[tex]\rm m =\dfrac{50-75}{2-0}[/tex]

m = -25/2

Thus, the value of the x-intercept is 6, the y-intercept is 75, and the value of the slope is -25/2.

The length of the ribbon used for the craft project is 3 meters

The length of ribbon need for the craft project = 114 inches

So, the length of the ribbon need to be in meters .

Thus, we can convert inched to centimeter by

                  1 inches = 2.54 centimeters

We know that 1 cm = 0.01 m

Thus , 1 inch = 2.54 x 0.01 m

          1 inch = 0.0254 m

Then for length of 114 inch ,

      114 inch = 0.0254 x 114 meters

                    = 2.89

                   ≈ 3 meters

Therefore , the length of the ribbon is 3 meters

(C): 3 meters.

Step-by-step explanation: The answer is 3 meters. The way to find this is relatively easy.

1. First, write 114 x 2.54.

2. Which is 289.56. Next, we convert 389.56 centimeters to meters.

3. That should give you 2.89. Because 8 is bigger than 4, we round up.

4. Now our answer is 3.

Answer:B 66.72

Step-by-step explanation:

complementary means if two angles are added up they will equal 90. we and eliminate d cause 23.28+23.28=46.56 so d is wrong now let's try c 46.56+23.28=69.84 so c is wrong cause it doesn't equal 90 now let's try a 156.72+23.28=180 its wrong since we are using complementary angles instead of supplementary angles Supplementary are angle two angles that add up to 180. so that just leaves b cause 23.28+66.72=90. i hope this helps and i made sure to explain it as best as i can have a great day

The solution is Option B.

The measure of the complementary angles are 66.72° and 23.28°

When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.

Let the first angle and second angle be a and b respectively such that

a + b = 90°

Given data ,

Let the first angle be represented as A

Now , the value of A is = 23.28°

Let the second angle be represented as B

Now , the value of B is = B

The angles A and B are complementary ,

So , A + B = 90°   be equation (1)

Substituting the values in the equation , we get

23.28° + B = 90°

On simplifying the equation , we get

Subtracting 23.28° on both sides of the equation , we get

B = 90° - 23.28°

B = 66.72°

Therefore , the value of B is 66.72°

Hence , the measure of the angle is 66.72°

The 20 in. by 20 in. cardboard used make the box by cutting out squares of length x from the corners gives;

The dimensions that will yield maximum volume are;

Length =

The dimensions of the cut square that gives the maximum volume is approximately 3.3 feet, while the dimensions of the box are;

Length; 13.3 feet

Width; 13.3 feet

Height; 3 feet

The maximum volume of the box is approximately 592.6 ft³

The maximum value of a function is the peak or highest point on the graph of the function.

The volume, V, of a box of Length, L, Width, W and Height, H, is given by the formula;

V = L×W×H

The length, width, and height of the box obtained by cutting a square of side length, x from the corners are;

Height of the box formed = x

Length of the cardboard box = 20 - 2•x

Width of the cardboard box = 20 - 2•x

The volume of the box is therefore;

V(x) = (20 - 2•x)•(20 - 2•x)•x = 4•x³ - 80•x² + 400•x

At the maximum point, we have;

V'(x) = (3×4)•x² - (2×80)•x + 400 = 0

V'(x) = 12•x² - 160•x + 400 = 0

Which gives;

3•x² - 40•x + 100 = 0

(3•x - 10)•(x - 10) = 0

Therefore;

[tex] \displaystyle{x = \frac{10}{3} }[/tex] and x = 10

When x = 10, we have;

V(10) = 4×10³ - 80×10² + 400×10 = 0

When x = 10/3, we have;

V(10) = 4×(10/3)³ - 80×(10/3)² + 400×(10/3) ≈ 592.6

Therefore, the dimensions of the box that gives the maximum volume is [tex] \displaystyle{x = \frac{10}{3} \approx 3.3}

The dimensions that yield maximum volume are therefore;

The maximum of the box is 592.6 ft³

Answer:

x = 2

Explanation:

The given expression is

7x - 4 - 3x = -3x + 10

First, we need to add the like terms on the left side

(7x - 3x) - 4 = -3x + 10

4x - 4 = -3x + 10

Add 4 to both sides

4x - 4 + 4 = -3x + 10 + 4

4x = -3x + 14

Add 3x to both sides

4x + 3x = -3x + 14 + 3x

7x = 14

Finally, divide by 7

7x/7 = 14/7

x = 2

Therefore, the answer is x = 2

The equation for the perpendicular bisector of the given line segment is y = 2x + 2.

Here, we are given a line segment with end points (3,−7) and (−9,−1)

Thus, the slope of the line can be calculated as-

(y1 - y2)/ (x2 - x1)

= (-1 + 7)/ (-9 - 3)

= 6/ -12

= -1/2

Now, since we the slope of 2 lines that are perpendicular to each other is negative of the reciprocal, thus-

slope of the perpendicular bisector = 2

Now, the midpoint of the given line segment will be-

{(x1 + x2)/2, (y1 + y2)/2}

= {(3-9)/2, (-7-1)/2}

= {-6/2, -8/2}

= (-3, -4)

Now, we can use the point slope form to find the equation of the perpendicular bisector-

(y- y1) = m(x - x1) where m is the slope and (x1, y1) is a point on the line.

⇒ (y+4) = 2(x+3)

y + 4 = 2x + 6

y = 2x + 2

Thus, the equation for the perpendicular bisector of the given line segment is y = 2x + 2.

The slope is -0.1 starting at 3.9, the GPA will decrease by 0.1 for each text sent in class.

Here we have to find the slope.

The equation given is:

y = 3.9 - 0.1x

As we know that the equation of a line is:

y = mx + c

Therefore we get that the slope is m = -0.1

Starting at 3.9 the GPA will decrease by 0.1 for every text sent in class ( for y = mx + b, a is the slope which is the coefficient of x)

Because the slope is less than 0, it is decreasing.

Therefore the slope is -0.1 and there is a decrease in GPA of 0.1.
