Answer:

A or $\frac{1}{2}x +2$

Step-by-step explanation:

Remember y=mx+b | m = slope & b = y intercept

Think back of rise over run. Where the rise is 1 and 2 is run. Now Also, lets not forget the y intercept which you can easily obtain by looking where the line intercepts the y axis. Which in this case it would be 2.

It’s the first one. The equation of a line is y=mx+b.

The y-intercept is represented by b, and it is 2, since the line crosses the y-axis at 2.

m is the slope of the equation, and you find that by using rise over run. You choose two points on the line and use the formula (x2-x1)/(y2-y1) to find the slope, which is 1/2.

You plug in b and m to get y=(1/2)x+2

Andy is buying a car.

Minchanka [31]

The amount payed each month by Andy is £ 504

Solution:

Given that, Andy is buying a car.

He negotiated a 7 percent decrease on a 6500 car.

Then, amount to be paid = 6500 – 7% of 6500

$\begin{array}{l}{\text { Amount to be paid }=6500 \times\left(1-\frac{7}{100}\right)} \\\\ {=6500 \times \frac{100-7}{100}=6500 \times \frac{93}{100}} \\\\ {\text { Amount to be paid }=65 \times 93=6045}\end{array}$

He will pay the full balance in 12 equal monthly payments.

We have to calculate the amount paid each month

$\begin{array}{l}{\text { monthly payment }=\frac{\text {total amount to be paid}}{12 \text { months }}} \\\\ {=\frac{6045}{12}=503.75}\end{array}$

Hence, Andy has to pay £ 504 approximately each month.

What is the measure of angle TRV? 20° 50° 60° 130°

kari74 [83]

130
srv is a straight line so angleSRV=180
TRV and SRT make up SRV so TRV + SRT = SRV.
(x-10) + (2x+10) = 180.
the 10s cancel each other out so 3x = 180
so x=60 bc 180/3=60. sub 60 for x in TRV and u get 130. sub 60 for x in SRT and you get 50, which, with 130 makes 180, so the answer is correct!
