Y = 15x <br> y = 25 + 12.5x

swat32

Substitute y = 15x to the equation y = 25 + 12.5x:

15x = 25 + 12.5x <em>subtract 12.5x from both sides</em>

2.5x = 25 <em>divide both sides by 2.5</em>

x = 10

Substitute the value of x to the equation y = 15x:

y = (15)(10)

y = 150

<h3>Answer: x = 10 and y = 150</h3>

ILL GIVE BRAINLEST, classify the triangle below with work please :)

Minchanka [31]

Answer:

A right triangle

Step-by-step explanation:

All interior angles in a triangle are equal to 180°.

x+x+2x = 180°

4x = 180°

x = 45°

So two of the angles are 45°, and the remaining angle is 45°×2 = 90° (a right angle).

Find the following when a = -1, b = 2, c = -1/4<br> (4b - 3)/(2a) -1

Katena32 [7]

We substitute the given into the equation
given: a=-1, b=2, c= $\frac{-1}{4}$
=( $\frac{4b-3}{2a}$ -1
= $\frac{4(2)-3}{2(-1)}$ -1
= $\frac{8-3}{-2}$ -1
= $\frac{5}{-2}$ -1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:
$\frac{5}{-2}$ =-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
= $\frac{5}{-2}$ $\frac{-1}{1}$ × $\frac{-2}{-2}$ (denominator should be -2=common)
= $\frac{5}{-2}$ + $\frac{2}{-2}$
= $\frac{7}{-2}$
which also = to -3.5
