The diagram tells us 3 things: the right angle and the two corresponding side measurements. Because the side measurements are corresponding, we can set a proportion:

6/9=9/15

If this proportion is true, it means the triangles are similar. If this proportion is impossible, it means the triangles are no similar.

To calculate this, we use cross multiplication.

6/9=9/15

6*15=9*9
90=81

90 does not equal 81 making this proportion impossible, which concludes that these two triangles are not similar.

I hope this helps! Please comment if you have any questions.

What is the slope, y-intercept, and equation of a line given the points (-4, 0) and (1, 5)?
Alex Ar [27]

Answer:

Slope: 1\\y-Intercept: 4\\Equation: y = x + 4

Step-by-step explanation:

Given two points, we can find the equation of the line between them with the following:

y = mx + b\\m = \frac{y_2-y_1}{x_2-x_1}

First, we can calculate m, or slope

m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-0}{1-(-4)}  = \frac{5}{5} = 1

Next we can use the top equation and solve for b, the y-intercept

y = mx + b\\y = x + b\\5 = (1) + b\\b = 4\\\\y = x + 4

Slope: 1\\y-Intercept: 4\\Equation: y = x + 4

What is the solution to the system of equations?
lesya692 [45]

Answer:

If you are asked if a point is a solution to an equation, we replace the variables with the given values and see if the 2 sides of the equation are equal (so is a solution), or not equal (so not a solution). A solution to a system of equations means the point must work in both equations in the system.
