Answer:

Output = (0.5)(Input) + 1.5

input = 1 , output = (0.5)(1) + 1.5 = 2

input = 3 , output = (0.5)(3) + 1.5 = 3

input = 5 , output = (0.5)(5) + 1.5 = 4

input = -1 , output = (0.5)(-1) + 1.5 = 1

1). Linear Combination (SHOW WORK)

Georgia [21]

Answer:

Part 1) The solution of the system of equations is (2,-5)

Part 2) The solution of the system of equations is (2,4)

Step-by-step explanation:

Part 1) Linear combination

we have

$3x+2y=-4$ -----> equation A

$4x-y=13$ -----> equation B

Multiply equation B by 2 both sides

$2(4x-y)=2*13$

$8x-2y=26$ -----> equation C

Adds equation A and equation C

$3x+2y=-4\\8x-2y=26\\-------\\3x+8x=-4+26\\11x=22\\x=2$

Find the value of y

$3(2)+2y=-4$

$2y=-4-6$

$2y=-10$

$y=-5$

The solution of the system of equations is (2,-5)

Part 2) By graph

$y=(1/2)x+3$ -----> equation A

$-3x+y=-2$ -----> equation B

we know that

The solution of the system of equations is the intersection point both graphs

Using a graphing tool

The intersection point is (2,4)

therefore

The solution of the system of equations is the point (2,4)

Answer:

2/8

Step-by-step explanation:

To find an equivalent of a fraction, multiply numerator and denominator by the same value:

1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8

Use the number line below, where RS = 7y + 2, ST = 2y +6, and RT = 13y - 12

Hitman42 [59]

Answer: a. y=5

b. RS = 37 , ST =16 and RT = 53 .

Step-by-step explanation:

Given: On number line we have,

RS = 7y + 2, ST = 2y +6, and RT = 13y - 12.

a. Since its on number line so we have

RT = RS+ ST

i.e. 13y - 12 = (7y + 2) + ( 2y +6)

⇒ 13y - 12 = 7y + 2 + 2y +6

⇒ 13y-12 = 9y+8

⇒ 13y-9y = 8+ 12 [Subtract 9y from both sides and add 12 in both sides]

⇒ 4y = 20

⇒ y= 5 [Divide both sides by 4 ]

b. Now , RS = 7(5) + 2 = 35+2= 37,

ST = 2y +6 = 2 (5)+6 = 10+6 =16,

and RT = 13y - 12 = 13 (5)-12 = 65-12 = 53.

Hence, RS = 37 , ST =16 and RT = 53 .
