Given equations A and B as 2/5x+y=12 and 5/2y-x=6 , respectively, which expression will eliminate the variable x?

Answers

Answer 1
Answer:

Answer:

 (2)/(5) × B + A

Step-by-step explanation:

Given equations are (2)/(5)x + y = 12 ---------(A)

and equation  (5)/(2)y - x = 6 -------------(B)

To eliminate the variable x we will multiply equation A by  (5)/(2)

and add it to equation B.

In other words, the expression that we will adopt to eliminate the variable x will be  (2)/(5) × B + A

Answer 2
Answer: Hello,

the answer is 5/2*A+B

B.
–14, 14

C.

98

D.
–98, 98

Answers

x^2 =196
x^2 -196=0
(x-14)*(x+14)=0
so (x-14)=0 && (x+14)=0
x=14 , -14
the answer is B

Answer:

14, -14

Step-by-step explanation:

x^2 = 196

x = √(196)

x = √(4 * 49)

x = √(4) * √(49)

x = 2 * 7

x = 14

Betty and Adam are playing cards. Betty has won 5 hands and Adam has won 20 hands. What is the ratio of the number of hands Betty has won to the number of hands Adam has won? A. 4:1 B. 1:4 C. 1:5 D. 5:1

Answers

Answer:

B. 1:4

Step-by-step explanation:

This problem is on ratio of quantities.

step one:

what is a ratio?

A ratio is a way of expressing the relation of one quantity to another, it is usaully expressed in fraction as x/y, x:y or sometime x is to y

step two:

given that Betty won 5 hands

and Adam won 20 hands

step three:

Therefore the ratio of the number of hands Betty has won to the number of hands Adam has won is

=5/20

=1/4

or simply put 1:4

80% of 120 is what value? 20 40 96 108

Answers

Create a graph of the combined function h(x) = f(x)/ g(x) in which f(x) = x - 6 and g(x) = x + 6.On your graph, show the graphs of f(x) and g(x) also.

Answers

Answer:

In the picture attached the graph of h(x) = f(x)/ g(x) = (x - 6)/(x + 6) is shown. Notice that there is no h(x) for x = -6. The graph was made with a computer software

f(x) = x - 6 and g(x) = x + 6 are also included. These two functions are continuous for all real numbers, despite that h(x) is not continuous in x = -6
