x-4y≤-12
-4y≤-x-12
4y≥x+12
y≥1/4x+3

Put (0,0)

0≥0+3 is false

Shading will be away from origin.

y inetercept

y=3(when x=0)

Check the direction of line by taking 4 and -4

y=4/4+3=y=4
y=-4/4+3=-1+3=2

The graph should bend down on left side while rise up in right side

Option A

5x-4y>4
-4y>-5x+4
4y<5x-4
y<5/4x-1

Putting origin in it

0>-1

Shading away from origin

And

x+y<2
y<2-x

Putting origin

Shading towards origin

Option B as shading should be downwards here

Answer:

BELOW

Step-by-step explanation:

DO I HEAR 100 POINTS? Yes.

For the first image, that answer is A.

For the second image, I'm a bit confused on which problems you want me to do, so I'll do number 10, 11, and 14.

10) Yeah, you're correct, it is J.

11) (1,-6), (-2,-5), (8,2) (4,0) and I can't see the last point so..

14) Can't see the question :(

find the missing angle and side measures of the triangle. The triangle has one angle that measures 90 degrees, and the other two

Tamiku [17]

Since we know that the measure of one of the angles is 90°, we know that we have a right triangle with legs 1 and $\sqrt{3}$ . Now lets apply the Pythagorean theorem: $hypotenuse= \sqrt{leg^{2}+leg^{2} }$ , to find our hypotenuse:
$h= \sqrt{1^{2}+ \sqrt{3}^{2} }$
$h= \sqrt{1+3}$
$h= \sqrt{4}$
$h=2$

Now that we know that the measure of the hypotenuse is 2, lets use the trig function sine to find one of the angles that we are going to call $x$ .
Remember that $sin(x)= \frac{opposite.side}{hypotenuse}$ , so:
$sin(x)= \frac{1}{2}$
$x=sin^{-1} ( \frac{1}{2} )$
$x=30$
Now that we have two angles, remember that the sum of the interior angles of a triangle is 180°; lets use that to find our final angle $y$ :
$y=180-(90+30)$
$y=180-120$
$y=60$

We can conclude that the measure of the hypotenuse of our triangle is 2, and the measure of its missing angles are 30° and 60° respectively.

A line contains the points (-26, -37) and (32, -61)

Slav-nsk [51]

The slope of line through given points is -12/29

Step-by-step explanation:

Given points are:

(-26, -37) and (32, -61)

Let

(x1,y1) =(-26, -37)

And

(x2,y2) = (32, -61)

Slope (steepness) of a line, denoted by m, is given by the formula

$m = \frac{y_2-y_1}{x_2-x_1}$

Putting the values

$m = \frac{-61-(-37)}{32-(-26)}\\\\=\frac{-61+37}{32+26}\\\\=\frac{-24}{58}\\\\=-\frac{12}{29}$

Hence,

The slope of line through given points is -12/29

Write the equation in slope-intercept form.<br> y - 6 = -2x

ser-zykov [4K]

Answer: y=-2x+6

Step-by-step explanation:

To write the equation in slope-intercept form, you want to solve for y.

y-6=-2x [add both sides by 6]

y=-2x+6

Now, we have the equation in slope-intercept form.
