Answer:

(b) and (c) are true

Step-by-step explanation:

Given

Function A and B

First, calculate the slope of A

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

[tex]m = \frac{24 - -21}{8- -7}[/tex]

[tex]m = \frac{45}{15}[/tex]

[tex]m =3[/tex]

The equation of function A is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 3(x - 8) + 24[/tex]

[tex]y = 3x - 24 + 24[/tex]

[tex]y = 3x[/tex]

The general form of a function is:

[tex]y = mx + b[/tex]

Where [tex]m = slope[/tex] and [tex]b = y\ intercept.[/tex]

This implies that:

[tex]Slope = 3[/tex]

[tex]Y\ intercept = 0[/tex]

For function B:

[tex]y = 4x - 3[/tex]

[tex]Slope = 4[/tex]

[tex]Y\ intercept = -3[/tex]

By comparison:

(b) and (c) are true

Answer:

I'm not sure if the bridge is 44 kilometers long or just 4, but if the bridge is 44 kilometers long it will take 22 hours but if the bridge is 4 kilometers long it will take 2 hours.

Step-by-step explanation:

Since her average speed is 2 kilometers per hour you just have to divide the length of the bridge by 2. Then your quotient or answer to the division equation will be the amount of time it takes to cross the bridge.

Answer:

22 hours

Step-by-step explanation:

i dont know if that is 100% correct because you wrote 4 4 and not 44 but used 44 in my calculations. also, i worked it out like this:

distance÷speed=time

44 km ÷ 2kph = 22

Answer:

The opposite side and opposite of angles of parallelogram are equal. An these opposite sides an opposite angles make up for a congruent triangles, with the two diagonal being the sides of these two congruent triangle. Hence the diagonals of the parallelogram are equal.

Answer:8.99 cm

Step-by-step explanation:

Answer:

[tex]8.995[/tex]cm

Step-by-step explanation:

The circumference formula is: [tex]C=2\pi r[/tex]

We are given the circumference, which is 56.52cm.

The question wants us to find the radius, r.

To achieve this, we must solve for r.

Plugging in 56.52 for C we get:

[tex]56.52=2\pi r[/tex]

Dividing both sides by [tex]2\pi[/tex], we find r:[tex]8.995[/tex]

[tex]\frac{56.52}{2\pi } =r[/tex]

[tex]8.995[/tex]≈[tex]r[/tex]

If you want to round it up, you can round it to 9cm.

y=5x +6

Another example would the line in standard form, 10x - 2y = 8.

Answer:

a) 77    b)B

Step-by-step explanation:

letterF is the same as 77 meaning that X will be the same as letterF cause the are vertically opposite angles.

I just did the question on math watch.

The measure of the angle ∠BFH that is 'x' will be 77 degrees. Then the correct option is B.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Alternate angle - If two lines are parallel then the third line will make z -an angle and z-angles equal angles with the parallel lines.

Line AD is parallel to line EH. And the line CG is the transversal line to line AD and EH.

The angle ∠FAB is congruent with the angle ∠BFH. Because they are alternate angles. Then we have

∠BFH = ∠FAB

x = 77°

The measure of the angle ∠BFH that is 'x' will be 77 degrees. Then the correct option is B.
