Answer:

Graph (2)

Step-by-step explanation:

We have to find the graph that represents the solutions of the quadratic equation as x = -4 and x = 2

Graph which has x-intercepts as x = 2 and x = -4 will be the answer.

Graph (1)

x-intercepts in this graph are x = -2 and x = 4

Not the answer.

Graph (2)

x-intercepts in this graph are x = -4 and x = 2

This option will be the answer.

Graph (3)

Only one x-intercept has been given in this graph

Not the answer.

Graph (4)

x-intercepts are x = -5 and x = -3

Not the answer.

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is
Yuri [45]

Answer:

x= 44 ounces y = 66 ounces  

Step-by-step explanation:

Distribution would be an increase to find 80% salt.

Where we use 4/5 = 80 but use here 4/5.

We find 19/20 but just say 95 for solution B =

Let x = the number of ounces of Solution A

Let y = the number of ounces of Solution B

x + y = 110        y = 110 - x

(70x + 95y) = 4/5 x 110

70x + 95y = 88    

70x + 95 y = 88

70x + 95 (88 - x) = 8800 make units equal or for start convert decimalization = same units as 2nd multiplied value.

70x + 8360 - 88x = 8800

-10x - 8360 - 8800 = y

-10x = 440

x = 44 ounces

y = 110- 44

y =  66 ounces

The midpoint of segment AB is (-7, 10) and endpoint A is located at (3, -1). Find the other endpoint B. Show all work.
dusya [7]

Answer:

B(-17,21)

Step-by-step explanation:

The midpoint of two points is the average of the x coordinates and the average of the y coordinates.

Given

A(3, -1)

and we let the other end point B be B(x,y)

and midpoint is (-7,10)

So, the average of 3 and x is -7, and

the average of -1 and y is 10

We can solve for x first:

\frac{3+x}{2}=-7\\3+x=2*-7\\3+x=-14\\x=-14-3\\x=-17

and now solving for y:

\frac{-1+y}{2}=10\\-1+y=2*10\\-1+y=20\\y=20+1\\y=21

So, the other point B is:

B(-17,21)

Find the greatest common factor of these three expressions. 5v2 , 14v4 , and 35
a_sh-v [17]

Question

Find the greatest common factor of these three expressions. 5v2 , 14v4 , and 35


Answer:

<h2>1</h2>

Step-by-step explanation:

assuming that 5v2 is 5², and 14v4 is 14^4

5² = 25

14^4 = 38416

35 = 35

The factors of 25 are: 1, 5, 25

The factors of 35 are: 1, 5, 7, 35

The factors of 38416 are: 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 343, 392, 686, 784, 1372, 2401, 2744, 4802, 5488, 9604, 19208, 38416

--------------

the greatest common factor is 1
