Find the value of the variable that results in congruent triangles
sdas [7]

Answer:

  y = 5

Step-by-step explanation:

The triangles will be congruent when corresponding sides are congruent. __

We already have ...

  KL ≅ NP . . . = 15 mm

  JL ≅ MP . . . = 22 mm

So, we need ...

  JK ≅ MN

  4y +12 = 32 . . . . substitute given values

This will be the case when ...

  4y = 20 . . . . . subtract 12

  y = 5 . . . . . . . divide by 4

The value of y that makes the triangles congruent is 5.

What is the surface area of the square pyramid?
e-lub [12.9K]

Answer:

SA = 16 units^2

Step-by-step explanation:

B - base

H - height

SA - surface area

B = 2

H = 3

SA = (B × B) + 4((1/2)×(B × H))

SA = (2×2) + 4((1/2)×(2×3))

What is the solution to the system of equations. 2x-y=7 y=2x+3
OLEGan [10]
To solve this, you can substitute the second equation into the first.

It becomes 2x-(2x+3)=7

Solve from here!

You get -3=7. Not possible. Therefore there is no solution to this system.

System is inconsistent. Hope this helps.

Can someone help me turn this into an inverse function? f(x) = 6-3x. and some explanations pls, bcuz Im still lost on this topic
sweet [91]

Answer:

y=-\frac{x-6}{3}

Step-by-step explanation:

To find the inverse function, switch the y and x

y=6-3x  becomes  x=6-3y.

Now, rearrange so that the equation is equal to y.

x=6-3y\\x-6=-3y\\-\frac{x-6}{3} =y

Hope this helps!
