Answer:

Slope-intercept form:

y = -12x + \frac{1}{2}

Step-by-step explanation:

-Since you already have the <u>slope</u> and the <u>y-intercept</u>, all you need is to apply them to a <u>slope-intercept form</u>:

Slope: -12

y-intercept: \frac{1}{2}

-Slope-intercept equation:

y = mx + b

(where m represents the <u>slope</u> and b represents the <u>y-intercept</u>)

-Applying to slope-intercept form:

y = -12x + \frac{1}{2}

And were done.

Answer:

Option D

Step-by-step explanation:

Slope intercept is:

y=mx+b

m - slope

b - y-intercept.

The slope in the question is -12. The y-intercept is 1/2.

Plug in the values:

y=mx+b\rightarrow \boxed{y=-12x+\frac{1}{2}}

Hope this helps.

a car dealer buys a luxury car for $65,200 and sells it for 85,650. What is the percent increase in the price of the cara car de
nika2105 [10]

Answer:

The percent increase in the price of the car is <u>31.36%</u>.

Step-by-step explanation:

Given:

A car dealer buys a luxury car for $65,200 and sells it for $85,650.  

Now, to find the percent increase in the price of the car.

Cost price of the luxury car = $65,200.

Sell price of the luxury car = $85,650.

So, the price of the car increased by:

Sell price of the luxury car - Cost price of the luxury car.

=\$85,650-\$65,200\\\\=\$20,450.

<em>Thus, the price of car increased by $20,450.</em>

Now,to get the percent increase in the price of the car:

\frac{20450}{65200} \times 100

=0.3136\times 100

=31.36\%.

Therefore, the percent increase in the price of the car is 31.36%.

Find m∠CXY<br> Please help with this, this is for my test review!!!
Murljashka [212]

Answer:

137°

Step-by-step explanation:

All angles in a triangle add up to 180° always.

Now imagine the two smaller shapes as a bigger triangle, CED.  The measure of angle CED is 89°, and CDE is 48°.  Do the math, and angle DCE is 43°.

But notice how the corresponding sides of the two smaller shapes are congruent.  (CX=XE, and DY=YE)  Meaning, the measure of angle C is equal to the measure of angle YXE.

We're almost there.  CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180.  180-43 = 137°.
