Answer:

The correct answer is the third option

Step-by-step explanation:

Have different slope but have the same y-intercept, so they have no solution.

y = 1/2x - 3

To graph this, the slope 1/2 which means go up once and to the right twice and b = -3, which means the y-intercept.

second equation:

y = -1/2x -3

To graph this, the slope -1/2 which means go down once and to the right twice and b = -3, which means the y-intercept.

Find the equation of the line graphed below. Write the equation in the form y = mx + b and identify m and b m = b =

Alla [95]

ANSWER:

m = -3/4

b = -3

$y=-\frac{3}{4}x-3$

STEP-BY-STEP EXPLANATION:

We have that the equation in its slope-intercept form is the following:

$\begin{gathered} y=mx+b \\ \text{where m is the slope and b is y-intercept} \end{gathered}$

We calculate the slope as follows:

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

To calculate the slope we use the intercepts that are (-4, 0) and (0, -3), we replace:

$m=\frac{-3-0}{0-(-4)}=\frac{-3}{4}=-\frac{3}{4}$

Now, the value of b would be -3, since the y-intercept is (0,-3), therefore, the equation would be:

$y=-\frac{3}{4}x-3$

Tell whether the given side lengths form a right triangle.<br> 6, 11, 16

Lubov Fominskaja [6]

Given:

The lengths of the sides of a triangle are 6, 11, 16.

To find:

Whether the given triangles is a right angle triangle or not.

Solution:

Pythagoras theorem:

$Hypotenuse^2=Perpendicular^2+Base^2$

A triangle is a right angle triangle if the sum of squares of two smaller sides is equal to the square of the largest sides.

In the given triangle the length of the largest side is 16.

Square of the largest sides is:

$16^2=256$

Sum of the squares of the two smaller sides is:

$6^2+11^2=36+121$

$6^2+11^2=157$

Since $6^2+11^2\neq 16^2$ , therefore the given triangle is not a right angle triangle.

Montano1993 [528]

Answer:

The new TV screen is 12.1 centimeters wide.

Step-by-step explanation:

Find 10% of 11:

0.10 x 11 = 1.1

Add 1.1 to the original size.

11 + 1.1 = 12.1
