Explain what the y-intercept of a line is

Answer:

A

Step-by-step explanation:

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope. The correct option is C.

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

Of the four of the given options, the options that are true are A and C, but since option, A says If two lines are parallel, then they do not intersect; T. Therefore, in the given option the result is given first and then the condition.

Opposite of that option C says If two lines do not intersect, then they are parallel; T. Therefore, it states the condition and then the answer. Thus, it is the correct option.

Hence, the correct option is C.

Step-by-step explanation:

Volume = base * height(depth)

V=1.2*1.35=1.62 m³

Answer:

Total amount she need = $44,444

Step-by-step explanation:

Given:

Amount Michelle needs = $42,000

Real state commission = 5.5%

Find:

Total amount she need

Computation:

Assume,

Total amount she need = x

So,

Real state commission = 0.055x

So,

x - 0.055x = 42000

x (0.945) = 42,000

x = 44,444 (Approx)

Total amount she need = $44,444

This question is Incomplete because it lacks the appropriate diagram for the square pyramid. Please kindly find attached the required diagram

Answer:

45 square inches

Step-by-step explanation:

From the question, we are told that the foil covers the body of the trophy including the bottom, hence the formula we would be applying =

Total Surface Area of the Square pyramid = 2bs + b²

Where s = Height of the square pyramid

b = Edge length of the square pyramid

From the attached diagram, we can see that:

s = 6 inches

b = 3 inches

Total Surface Area of the Square pyramid = 2bs + b²

= 2 × 3 × 6 + 3²

= 36 + 9

= 45 square inches.

Therefore, the amount of gold foil it took to cover the trophy, including the bottom is 45 square inches

Answer:

13.44 pounds

Step-by-step explanation:

3.2x4.2=13.44 or 13 and 11/25

13.44 pounds of newspapers were collected by Rudy.

Two or more expressions with an Equal sign is called as Equation.

Given that alya collected [tex]3\frac{1}{5}[/tex] pounds of newspaper for the recycling Drive

Rudy collected [tex]4\frac{1}{5}[/tex] times as much newspaper as a liar

We need to find how many pounds of newspaper did Rudy collect​.

Let us convert  [tex]3\frac{1}{5}[/tex] as improper fraction

[tex]3\frac{1}{5}[/tex]=16/5

[tex]4\frac{1}{5}[/tex] =21/5

As Rudy collected 4 1/5 times as much newspaper of alya

So multiply 16/5 with 21/5

16/5×21/5

3.2×4.2

13.44 pounds

Hence, 13.44 pounds of newspapers were collected by Rudy.

Answer:

(3,0)

Step-by-step explanation:

Co-ordinates of J =(4,3)

Co-ordinates of K = (2,-3)

Midpoint formula :

 = [tex]\frac{x_{1}+x_{2} }{2} , \frac{y_{1} +y_{2} }{2} \\ \frac{4+2}{2} ,\frac{3+(-3)}{2}\\\frac{6}{2},\frac{3-3}{2}\\3, 0[/tex]

Coordinates of the midpoint M (3,0)

The coordinates of the midpoint M is (3,0) and the distance between J(4,3) and K(2,-3) is 6.32 units.

The distance between two points of the xy-plane can be found using the distance formula. The distance formula is:

√[(x₂ - x₁)² + (y₂ - y₁)²].

Now given coordinates of two points are,

J(4,3) and K(2,-3)

Therefore we have,

x₁ = 4

y₁ = 3

x₂ = 2

y₂ = -3

To find the midpoint between J and K we have,

{[(x₁+x₂ )/2] , [(y₁+y₂ )/2]}

Put the values, we get

{[(4+2)/2] , [(3+(-3)/2]}

solving them,

{(6/2) ,(0/2)}

or,

(3,0)

which is the required midpoint M.

Now distance between J(4,3) and K(2,-3) = √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(2 - 4)² + (-3 - 3)²]

= √[(- 2)² + (-6)²]

= √4 +36

= √40

= 6.32 units

Thus, the coordinates of the midpoint M is (3,0) and the distance between J(4,3) and K(2,-3) is 6.32 units.

Answer:

width = 6 ft

Step-by-step explanation:

let  A = 24 3/5 = (24*5 +3)/5 = 123/5 ft^2 the area

l = 4 1/10 = (4*10 + 1)/10 = 41/10 ft the length

w = the width, w>0

since the area = length*width we have:

l*w = A

(41/10)*w = 123/5

by solving we find:

w = 6 ft

Step-by-step explanation:

Nesta pergunta, queremos calcular a probabilidade de que uma bola retirada da urna não seja preta.

Existem três cores, uma vez que a bola removida não é preta, então é uma das outras duas cores.

Isso significa que a bola é branca ou vermelha. Observe que a probabilidade de a bola não ser preta é 1 menos a probabilidade de a bola ser preta Vamos descobrir a probabilidade de que a bola seja preta;

Matematicamente, isso seria;

número de bolas pretas / número total de bolas.

O número total de bolas é; 10 + 5 + 4 = 19 número de bolas pretas = 4

A probabilidade de a bola ser preta é de 4/19

Portanto, a probabilidade de que a bola não seja uma bola preta é

1 - 4/19 = 15/19

Answer:

A: Linear

B: Linear

C: Linear

Step-by-step explanation:

So we have three functions:

[tex]f(x)=3x+1\\f(x)=x-6x+5\\f(x)=4x-x+1[/tex]

To determine the type of graph for each function, simplify each of them and then we can determine whether it's linear or quadratic.

1)

We have:

[tex]f(x)=3x+1[/tex]

This has a degree of 1. Quadratics have a degree of 2. In other words, quadratics have a x^2 term. There isn't one here, so this is a linear equation.

2)

We have:

[tex]f(x)=x-6x+5[/tex]

Simplify:

[tex]f(x)=-5x+5[/tex]

Again, this is of degree 1. There is no x^2 term. Thus, this is also a linear equation.

3)

We have:

[tex]f(x)=4x-x+1[/tex]

Simplify:

[tex]f(x)=3x+1[/tex]

This has a degree of 1. There is no x^2 term. Thus, this is also a linear equation.

Answer:

Step-by-step explanation:

a- f(x)=3x+1 it is linear equation

b: f(x)=x-6x+5

f(x)=-5x+5  linear equation

c: f(x)=4x-x+1

f(x)=3x+1  (linear equation)

(if there is no exponent then the graph is linear)
