Mathematics

Answer:

1. No solution

2. Infinite solutions

Step-by-step explanation:

1. To solve the system, set the equations equal to each other and solve for x.

2x - 5 = 2x + 7

-5 = 7

This is a false statement. This means there is no solution.

2. To solve the system, graph each equation.

y = -3/4 x - 5/2 has a y-intercept -5/2 and slope -3/4.

3x + 4y = -10 converts to y = -3/4x -5/2.

This graphs as the exact same line. This system has infinite solutions.

A car dealer's markup on every car they sell is 20%. For what price did the dealership buy a car that they sold for $18,600?

elena-s [515]

Answer:

buying price = $15,500

Step-by-step explanation:

selling price 20% more than the buying price

let the buying price be 100% then;

selling price = 120%

120% = $18,600

100% = ?

(100 × 18600) ÷ 120

= $15,500

Which of the following is a factor of 2xy + 8y − 8x − 32?

melamori03 [73]

We are given

$2xy+8y-8x-32$

We can write it as

$=2y*x+2y*4-8*x-8*4$

we can see that 2y is in first two terms

and -8 is in last two terms

so, we can factor it out

$=2y(x+4)-8(x+4)$

now, we can see that x+4 is common in both terms

so, we can factor it out

$=(x+4)(2y-8)$

we can see that

x+4 is one of factor of terms

so, option-B..........Answer

Determine which of the following graphs does not represent a function.

levacccp [35]

let's recall the vertical line test, it's a function if when dropping a vertical line on the graph, it only touches it once on the way down.

Check the picture below.

Find the area of the figure shown.

lara [203]

The '4' marked in the cut-out must be its width, because it can't be the height ... the height of the cut-out must be 3. / / / The area of the entire big rectangle is 12 x 14 = 168. The area of the little cut-out is 4 x 3 = 12. The area left is 168 - 12 = 154 ./ / / By the way ... if you're not getting many answers, it's because your drawings are unreadable. Put away the big orange marker and use a ballpoint pen instead.

Solve for x.<br> x + 14<br> 5x - 74<br> x = [?]

otez555 [7]

Answer:

$\huge \fbox \pink {A}\huge \fbox \green {n}\huge \fbox \blue {s}\huge \fbox \red {w}\huge \fbox \purple {e}\huge \fbox \orange {r}$

x + 14 = 5x - 74 (corresponding angles are equal to each other)

$x + 14 = 5x - 74 \\ 14 + 74 = 5x - x \\ 88 = 4x \\ \frac{88}{4} = x \\ 22 = x$
