Answer:

The slope is 0

Step-by-step explanation:

Points on the graph:

(5, -4) and (7, -4)

Slope:

m=(y2 - y1)/(x2 - x1)

m=(-4 + 4)/(7 - 5)

m= 0/2

m=0

When they are both racing on hoverboards, Victoria is 3 times as fast as her brother Max. When she is on foot, she is 3 times sl

NARA [144]

Answer:

Race completed in 48 minutes.

Step-by-step explanation:

Let the speed of Max on hoverboard is = x

Then as per question speed of Victoria on hoverboard = 3x

Now it has been given in the question that speed of Victoria on foot is 1/3 of the speed of Max on hoverboard that will be = x/3

Now we will form the equation.

As we know the formula speed = distance/time

Let the time taken by both to complete the race be t minutes.

Distance covered by Victoria in 12 minutes + Distance covered by Victoria on foot = distance covered by Max on hoverboard

Then the equation will be

12(3x)+(1/3)x(t-12)=xt

$36x+\frac{xt}{3}-4x=xt$

$x(36+\frac{t}{3}-4)=xt$

$36+\frac{t}{3}-4=t$

$32=t-\frac{t}{3}$

$\frac{2t}{3}=32$

$t=\frac{(32)3}{2}=48$

So 48 minutes it took to complete the race.

Perform the addition.<br> (3x² + 3x - 5) + (-7x² + 9)

lakkis [162]

The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
$(3 x^{2} + 3x - 5) + (-7 x^{2} + 9)$ <span>
Use distributive property:
</span> $3 x^{2} + 3x - 5 - 7 x^{2} + 9$
Combine Like Terms:
$
-4 x^{2} +3x+4$
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!

andrew11 [14]

Answer:

30 degrees.

Step-by-step explanation:

The ladder that extends from the floor to the storeroom makes a right triangle. The ramp is the hypotenuse measuring 10 m and the elevation of the storeroom is the opposite side. The angle of elevation is the arcsin of the quotient of the 5/10. Thus, the answer is 30 degrees.
