Answer:

<h2>Yes. It's a right triangle.</h2>

Step-by-step explanation:

If a ≤ b < c are the length of the sides of a right triangle, then

a² + b² = c².

We have:

a =30 ft, b = 40 ft and c = 50 ft.

Check the equality:

L = 30² + 40² = 900 + 1600 = 2500

R = 50² = 2500

L = R

At George Washington High School, the ratio of graduating seniors that go on to college compared to those who do not is 7 : 4. L
wolverine [178]
Hi, thank you for posting your question here at Brainly.

This problem can be solved easily by applying ratio and proportion. In this case, the ratio between those who go to college and those who do not is 7/4. Then, when there are 28 students, you can determine the number of which who don't go to college by using the 7/4 ratio value

7/4 = 28/x
x = 16

Thus, 16 students did not go on to college.

Please help, I miss one day and I dont know how to do this
valentinak56 [21]

Answer:

X is 12 Y is 124

Step-by-step explanation:

left and right side have equal degrees of 56

so x would be 12 because you would multiply 4×12

since in total it will be 360 degrees

you add 56 and 56 together to get 112

then just subtract 112 from 360 and you get 248 then divide 248 by 2 and you have your bottom and top value of 124

Complete the equation of the line whose interpret is (9.0) and slope is -2. Remember to use y=mx+b format
kenny6666 [7]

Answer:

y = - 2x + 18

Step-by-step explanation:

Step 1:

y = mx + b          Slope Intercept Form

Step 2:

y = - 2x + b         Input Slope Value

Step 3:

0 = - 2 ( 9 ) + b           Input x and y values

Step 4:

0 = - 18 + b        Multiply

Step 5:

b = 18          Add 18 on both sides

Answer:

y = - 2x + 18

Hope This Helps :)

The black graph is the graph of y=f(x). Choose the equation for the red graph.<br> Please Help me!!
katen-ka-za [31]

Answer:

c

Step-by-step explanation:

The red graph is the black graph translated vertically by 1 unit

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Thus f(x) + 1

Note

y - 1 = f(x) ← add 1 to both sides

y = f(x) + 1 ← as required

The equation of the red graph is

y - 1 = f(x) → c

Hurry in test Brainliest!!!
tamaranim1 [39]

Answer:

<em>y = (x - 4) - 4 </em>

Step-by-step explanation:

m = \frac{y_{2} - y_{1} }{x_{2} -x_{1} }

(- 2, - 10)

(4 , - 4)

m = \frac{-4+10}{4+2} = 1

y + 4 = (x - 4) ⇒ <em>y = (x - 4) - 4</em>
