{-4x+7y+5=-5
{0x-3y=-5 Solve the equation.

{-4x+7y+5=-5
{y=5/3 Substitute the value of y.

-4x+7(5/3)+5=-5 Plug in and solve.

x=65/12 You should get this answer.

Therefore: (x,y) = (65/12,5/3)

What is the measure of angle B in the triangle? Enter your answer in the box.
eduard
The triangle angle-sum theorem says that all those angles added together equal 180.  Therefore, 120+x+x+16=180 and 2x+136=180 and 2x=44.  Therefore, x = 22, which is angle B.

Answer:

<em>The Graph is shown below</em>

Step-by-step explanation:

<u>The Graph of a Function</u>

Given the function:

\displaystyle y=g(x)=-\frac{3}{2}(x-2)^2

It's required to plot the graph of g(x). Let's give x some values:

x={-2,0,2,4,6}

And calculate the values of y:

\displaystyle y=g(-2)=-\frac{3}{2}(-2-2)^2=-\frac{3}{2}(-4)^2==-\frac{3}{2}*16=-24

Point (-2,-24)

\displaystyle y=g(0)=-\frac{3}{2}(0-2)^2=-\frac{3}{2}(-2)^2=-\frac{3}{2}*4=-6

Point (0,-6)

\displaystyle y=g(2)=-\frac{3}{2}(2-2)^2=-\frac{3}{2}(0)^2=0

Point (2,0)

\displaystyle y=g(4)=-\frac{3}{2}(4-2)^2=-\frac{3}{2}(2)^2=-\frac{3}{2}*4=-6

Point (4,-6)

\displaystyle y=g(6)=-\frac{3}{2}(6-2)^2=-\frac{3}{2}(4)^2=-\frac{3}{2}*16=-24

Point (6,-24)

The graph is shown in the image below

Larry buys a tent that is on sale for 25% off the original price. The original price is $80 more than the sale price. What is th
myrzilka [38]

Answer:

The original price of the tent = $320

Step-by-step explanation:

Let the original price be =$ x

Discount offered  = 25% of the orignal price = \frac{25}{100}\times x=0.25\times x =\$ 0.25x

Original price is $80 more than sale price

Discount = Original price - Sale price = $80

So, we have

0.25x=80

We need to solve for x to find original price

Dividing both sides by 0.25

\frac{0.25}{0.25}x=\frac{80}{0.25}\\x=\$320

∴ The original price of the tent = $320
