Answer:

B) 1

Step-by-step explanation:

Since we are using elimination, we can just cancel 2y and -2y. No need of multiplying anything if we are just looking for x.

We add the equations and get:

9x=9

Then divide and the final answer is:

x=1

Can a triangle have sides of lengths 9,17,15? Show why or why not.

Elden [556K]

Answer:

A triangle has 3 sides: a, b, c satisfying inequalities below:

=> a + b > c > |a - b|

=> b + c > a > |b - c|

=> c + a > b > |c - a|

9, 15, 17 satisfy the inequalities above (you can check it easily).

Hope this helps!

( There are two similar triangles on the graph below. Use the graph to answer the questions. You must answer each question AND e

Evgen [1.6K]

Answer:

The Slope of both the lines is the same.

Step-by-step explanation:

Given two co-ordinates (x1, y1) and (x2, y2), the slope of a line can be found using the formula:

$slope = \frac{y2-y1}{x2-x1}$

For the diagonal line of the first triangle, the coordinates are (0, 0) and (2, 1)

$slope of diagonal line of first triangle = \frac{1 - 0}{2 - 0} = \frac{1}{2}$

For the diagonal line of the large triangle, the coordinates are (2, 1) and (6, 3)

$slope of diagonal line of second triangle = \frac{3-1}{6-2} = \frac{2}{4} = \frac{1}{2}$

Rearrange the formula to make t the subject:<br> S=d/t

Virty [35]

Answer:

t = d/S

Step-by-step explanation:

S = d/t

Cross multiply

S x t = d

Divide both sides by S

S/S x t = d/S

t = d/S
