Answer:

A)  \frac{5}{7}

Step-by-step explanation:

Use the two-points formula for the slope of a line.

We know that the points (2,-2) and (9,3) are on the line. If (a,b),(c,d) are points on a line then the slope m is defined by the equation m=\frac{d-b}{c-a}. In this case, a=2,b=-2,c=9 and d=3 then the slope is m=\frac{3-(-2)}{9-2}=\frac{5}{7}.

starting at home, Omar traveled uphill to the gift store for 30 minutes at just 10mph. He then travelled back home along the sam
SashulF [63]

Answer:

average speed for the entire trip is 15 mph

Step-by-step explanation:

Let x be the uphill speed and y be the downhill speed.

We have been given that

Speed of Omar in uphill to reach gift store = x =10 mph

Speed of Omar in downhill to reach his home = y = 30 mph

We know the formula for average speed for the entire trip

\text{Average speed }=\frac{2xy}{x+y}\\\\=\frac{2\times 10\times 30}{10+30}\\\\=\frac{600}{40}\\\\=15

Therefore, average speed is 15 mph

Can you guys please help me posted picture of question
Dimas [21]
Number of outcomes of rolling a die = 6
Number of outcomes from the spinner = 8

First we have to draw the 6 leaves to represent the 6 outcomes of rolling the die. Next on each of these leaves 8 possible outcomes of the spinner will be drawn using leaves.

So 6 leaves are being divided into further 8 leaves.

Thus total number of leaves will be  = 6 x 8 = 48 leaves

Therefore, the correct answer is option D

Write the equation of the line that’s tangent to the given function at x=1 f(x)= two x to the third power minus four x
Aliun [14]

f(x)=2x^3-4x

take the derivitive to find the slope

f'(x)=3*(2x^2)-2*(4x^0)

f'(x)=6x^2-4

so at x=1, the slope is f'(1)=6(1)^2-4=6-4=2


y=mx+b

y=2x+b

find b

at x=1, f(1)=2(1)^3-4(1)=2-4=-2=y

-2=2(1)+b

-2=2+b

-4=b

equation is y=2x-4
