5x( 4y2 + 5z) – (4y2 + 52

Mathematics

Hello! :)

To solve your equation, we will simplify

5 x (4y^2 + 5z) - (4y^2 +52)

Let's Distribute the negative sign

5 x (4y^2 + 5z) + −1 (4y^2 + 52)

5x (4y^2 + 5z) + −1 (4y^2) + (−1) (52)

5x (4y^2 + 5z) + −4y^2 + −52

Now, we will Distribute

(5x) (4y2)+(5x) (5z) + -4y^2 + -52

20xy^2 + 25xz + −4y^2 + −52

Hope this helped you!

PLEASE HELP !! ILL GIVE BRAINLIEST *EXTRA 40 POINTS* DONT SKIP :(( .!
Burka [1]

Answer:

B) Angle 2 and Angle 3

Step-by-step explanation:

Angle 2 and Angle 3 are equal since they're vertical angles and aren't supplementary

Angle 7 and 8 are supplementary

Angle 1 and 7 are supplementary

Honestly, i have no clue with angle 4 and angle 4. I just know that vertical angles aren't supplementary because they're equal to each other so I'll assume this is the case as well.

What is the value of x in the equation 3x- 4y =65, when y= 4?
Alexus [3.1K]
3x-4y=65

3x=65+4y

x=(65+4y)/3, when y=4

x=(65+4*4)/3

x=(65+16)/3

x=81/3

x=27

A parabola has an x-intercept of -1, a y-intercept of -3, and a minimum of -4 at x = 1.
torisob [31]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

y=a(x-h)^{2}+k

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(1,-4)

substitute

y=a(x-1)^{2}-4

we have

An x-intercept of (-1,0)

substitute and solve for a

0=a(-1-1)^{2}-4

0=4a-4

4a=4

a=1

The equation is

y=(x-1)^{2}-4

<u><em>Verify the y-intercept</em></u>

For x=0

y=(0-1)^{2}-4

y=-3

The y-intercept is the point (0,-3) -----> is correct

using a graphing tool

see the attached figure
