The answer to this question is Y= -1/3 - 2

The equation is y = -1/3x-2.

To determine the equation, I remembered that for a equation to be perpendicular of another, the original slope will be the reciprocal. So, -3 will turn into -1/3. Then I written the equation y=mx + b. I wrote out -4 = -1/3 (6) + b because I plugged in the x and y values. Then I solved for b. The result I got for b was -2.

After solving for b, the equation I found was y= -1/3x-2

Answer : 96

x – y = 16 --------> equation 1

$\frac{1}{8} x +\frac{1}{2} y = 52$

x is the higher grade and y is the lower grade

We solve the first equation for y

x - y = 16

-y = 16 -x ( divide each term by -1)

y = -16 + x

Now substitute y in second equation

$\frac{1}{8} x +\frac{1}{2} ( -16 + x ) = 52$

$\frac{1}{8} x - 8 + \frac{1}{2} x = 52$

$\frac{1}{8} x + \frac{1}{2} x - 8 = 52$

Take common denominator to combine fractions

$\frac{1}{8} x + \frac{4}{8} x -8 = 52$

$\frac{5}{8} x - 8 = 52$

Add 8 on both sides

$\frac{5}{8} x = 60$

Multiply both sides by $\frac{8}{5}$

x = 96

We know x is the higher grade

96 is the higher grade of Jose’s two tests.

7+ 3x+4 I need the answer for this too please thanks

Stolb23 [73]

We can't give you answer for x because it's an expression, not an equation.

I can simplify it though:

7 + 3x + 4

Step 1: Combine like terms:

7 + 4 + 3x

11 + 3x

Give the equation of a line that is perpendicular to the line y= -4/5x+8

amm1812

Answer:

y = 5/4x

Step-by-step explanation:

The given line is written in slope-intercept form. In this form, the slope is the coefficient of x, -4/5.

The perpendicular line will have a slope that is the opposite reciprocal of this value:

-1/(-4/5) = 5/4

The simplest such line is the one that goes through the origin:

y = 5/4x
