Y=-1x+11.

I used an online graph for this and it would be tricky on paper.

This has a few steps. First, solve for m by plugging in x = 8, y = 3.
3 = 8m + 11 => m = -1. This is the slope of the equation. Now just plug this into the original equation.
So the solution is y = (-1)x + 11.

y = -x + 11

12=q+23 I need help Im not good with fractions

Afina-wow [57]

Answer:

$12 = q + 23 \\ - q = 23 - 12 \\ - q = 11 \\ \frac{ - q}{ -1 } = \frac{11}{ - 1} \\ q = - 11$

it is actually kinda easy u just need to think harder but I still hope it helps

Plzz help Solve for x x ÷3 3/10 =2 2/5

Svet_ta [14]

Answer:

$\huge\boxed{x=7\dfrac{23}{25}}$

Step-by-step explanation:

$x\div3\dfrac{3}{10}=2\dfrac{2}{5}\\\\\text{convert the mixed number to the impropper fraction}\\\\3\dfrac{3}{10}=\dfrac{3\cdot10+3}{10}=\dfrac{33}{10}\\\\2\dfrac{2}{5}=\dfrac{2\cdot5+2}{5}=\dfrac{12}{5}\\\\x\div\dfrac{33}{10}=\dfrac{12}{5}\\\\x\times\dfrac{10}{33}=\dfrac{12}{5}\qquad\text{multiply both sides by}\ \dfrac{33}{10}\\\\x\times\dfrac{10\!\!\!\!\!\diagup}{33\!\!\!\!\!\diagup}\times\dfrac{33\!\!\!\!\!\diagup}{10\!\!\!\!\!\diagup}=\dfrac{12}{5}\times\dfrac{33}{10}\\\\x=\dfrac{396}{50}$

$x=\dfrac{198}{25}\\\\x=\dfrac{175+23}{25}\\\\x=\dfrac{175}{25}+\dfrac{23}{25}\\\\x=7\dfrac{23}{25}$

Answer:

B. positive numbers and zero

Step-by-step explanation:

This is a square root function:

f(x) = 3√x

The domain is the x-values which include all non-negative real numbers

Oof this is probably really simple to most of y'all but I'm out of it.

Lelechka [254]

Answers:

angle1 = 156 degrees
angle2 = 24 degrees

=======================================================

Explanation:

The two angles form a straight line, which is 180 degrees

Add up the angle expressions and set the sum equal to 180.

(angle1) + (angle2) = 180

(4x) + (x-15) = 180

(4x+x)-15 = 180

5x-15 = 180

5x = 180+15

5x = 195

x = 195/5

x = 39

We use that x value to find each missing angle

angle1 = 4x = 4*39 = 156 degrees
angle2 = x-15 = 39-15 = 24 degrees

Then notice how angle1+angle2 = 156+24 = 180 to verify the answer.

Side note: Angles that add to 180 are considered supplementary.
