Find the solutions of y= x+2
y=4-x

Answers

Answer 1
Answer:

y= x+2

y=4-x

so

x + 2 = 4 - x

2x = 2

x = 1


y = 1 + 2

y = 3


Answer

x = 1, y = 3
Answer 2
Answer:

y= x + 2

y= 4 - x


Let (y= x+2) be y

x+2 = 4- x

x + x = 4 - 2

2x = 2

Therefore x= 1


Lets now find y;

y= x+2

lets replace x with 1 ( x=1)

y= 1+2

y= 3

The answer therefore is y=3 and x= 1

Find the value of Z in the following equation: 8Z = 64.a. 72
B. 8
C. 512
D. 56

Answers

The requried simplified value of z is given as z = 8. Option B is correct.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

Given expression,
8z = 64
divide both sides by 8
8z / 8= 64 /8
z = 8

Thus, the requried simplified value of z is given as z = 8. Option B is correct.

8Z = 64

Divide both sides by 8.

8Z/8 = 64/8

Z = 64/8

Z = 8

Person A speaks the truth 88% of the time. The probability of person B speaking the truth on an occasion that person A also speaks the truth is 43%. What is the probability that person A speaks the truth, but person B lies?

Answers


we are given the probability that is 88% of  person A speaking the truth. The probability of person B speaking the truth on an occasion that person A also speaks the truth is 43%. This means the probability that person A speaks the truth, but person B lies 0.88*(1-0.43) equal to 0.5016

There are many cylinders with a height of 9inches. Let r represent the radius in inches and v represent the volume in cubic inches what belongs in cell A

Answers

Complete question :

There are many cylinders with a height of 9 inches. Let r represent the radius in inches and V represent the volume in cubic inches.

a. Complete the table relating the radius and volume of cylinders with height 9 inches. Write each volume as a multiple of , or round to the nearest cubic inch.

Answer:

A = 9π in³

B = 36π in³

C = 81π in³

Step-by-step explanation:

Radius, r = 1, 2, 3

Height of cylinder = 9

Volume, V of cylinder : πr²h

For, r = 1

V = π(1)²9 = 9π in³

For, r = 2

V = π(2)²9 = 4*9π in³ = 36π in³

For r = 3

V = π(3)²9 = 9*9π in³ = 81π in³

Each month Allison gets a $15 allowance and earns $100 working at the theater. She uses the expression 15x+100y to keep track of her earnings Part A Part B Part C

Answers

Step-by-step explanation:

The expression for he earning of Allison and her allowance is as follows :

15x+100y

Part A

Variables are x and y. Coefficients are 15 and 100.

Part (B)

There are two terms in this expression. + is used to separate the terms. 15x and 100y are the terms.

Part (C) As $15 shows her earning from allowances. Hence, 15x shows allowance.
