\large\orange\implies \rm \large \:f(x) \:  =  \: 2x

We have to find x when f(x) is 8

\large\orange\implies \rm \large \:8 =  \: 2x

\large\orange\implies \rm \large \:  \cancel\frac{8}{2}  \:  =  \: x \\

\large\orange\implies \rm \large \: \: 4 \:  =  \: x

A line passes through (6, 3), (8, 4), and (n, -2). Find the value of n.
timurjin [86]

Answer:

n = -4

Step-by-step explanation:

Notice how in the previous examples they all divide by 2? It is the same case here. So now the question is... "what" divided by "2" is "-2".

Let me show you:

n ÷ 2 = -2

if you know your integer math, you should know that...

-4 ÷2 = -2 (this is the correct equation)

Can someone please help me with this :(
mrs_skeptik [129]

Answer:

first find the surface area of one of the square and one of the triangle.

then multiple it by the number of square and triangle they have

finally add the total surface area of the triangle with the total surface area of the square.

Step-by-step explanation:

  1. for one square

area= base * width

= 10*10

=100

total area of square= number of square * area of one square

t=6*100

t=600

  • for one triangle

area = 1/2 base * height

= 1/2 *10*8.66

=43.3

total area of triangle=number of triangle* area of one triangle

t2=8*43.3

=346.4

total surface area= total surface area of the square+ total surface area of the triangle

=600+346.4

=946.4 in^2

A runner runs 8 miles in 92 minutes what is the runner’s unit rate?
nikitadnepr [17]

Answer:

The runner's unit rate is 0.09 miles/minute.

Step-by-step explanation:

Given:

Distance cover by runner = 8 miles and the time taken = 92 minutes.

Now, to calculate the runner's unit rate.

We put the formula to get the unit rate:

Velocity = distance/time

v=\frac{d}{t}

v=\frac{8}{92}

v=0.0869

v = 0.09 miles/minute (approximately)

Therefore, the runner's unit rate is 0.09 miles/minute.
