how to know if lines are proportional

Answers

Answer 1

Answer:

normally they'll be the same length, or you can multiply one line by a number to get the other line

Answer 2

Answer:

A line is proportional if the y-intercept is at 0,0. So your equation might look like y=4x. But it can't be y=4x+1. Since then the y intercept is at 0,1.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Alice went shopping at a kids' clothing store, where the shirts and pants were the same price.

Let's suppose the price for each shirt and each pant is $x

She also bought $6.

So we can model a linear equation in one variable:

9x + 4x + 6 = 71

13x = 65

x = $5

Thus, the price for each shirt and each pair is $5 if she bought 9 shirts and 4 pairs of pants, and she also bought a toy for $6. She spent a total of $71 option (C) is correct.

The Marine Discovery Aquarium sells ocean-themed cookies in their gift shop. Last month, they sold 65 shark cookies and 85 clown fish cookies. The cookies were so popular that they want to order more cookies this month. They plan to order 170 clown fish cookies this month. If they keep the same ratio, how many shark cookies should they order this month?

Answers

Answer: 130 shark cookies.

Step-by-step explanation: If you divided 170 clown fidh cookies by 85 clown fish cookies you get 2. So same as 85 times 2. Then do the same with the shark cookies. 65 times 2, that equals 130.

Answers

Complete question :

Ned is riding his bike from his house to the park, both of which are on the same straight road. On his way, he stops at a store, which is 4/7 of the way to the park, and then bikes the remaining 0.6 mile to the park. What is the distance between Ned's home and the park?

Answer:

1.4 miles

Step-by-step explanation:

Given that :

Ned's home and park are on the same straight road :

Store where Ned stopped is 4/7 of the way to the park

Bikes the remaining 0.6 miles to the park

Hence after traveling 4/7 of the distance, distance to park is 0.6 miles

Hence, 1 - 4/7 = 3/7

Hence, 3/7 of the way = 0.6 miles

If 3/7 = 0.6 miles

Then, 1 = x

Cross multiply

3/7 x = 0.6

3x = 4.2

x = 4.2 / 3

x = 1.4 miles

The distance from Ned's home to park is 1.4 miles

The distance between Ned's home and the park is 1.4 miles.

Ned is riding his bike from his house to the park, both of which are on the same straight road.

At some point between the way to the park, he covered [tex]\dfrac{4}{7}[/tex] of total distance and the destiny is still remained by 0.6 mile.

The fraction of the distance yet to be covered is,

[tex]\begin{aligned}\rm{Remaining\;distance}&=1-\dfrac{4}{7}\\&=\dfrac{7-4}{7}\\&=\dfrac{3}{7} \end{aligned}[/tex]

Now, the remaining distance is given that is 0.6 mile.

Therefore,

[tex]\begin{aligned}\dfrac{3}{7} \times \rm{Total \;distance}&=0.6\\\rm{Total \;distance}&=1.4\;\rm{miles} \end{aligned}[/tex]

Thus, the distance between Ned's home and the park is 1.4 miles.

Answers

Answer:

Domain: {0, 2, 5}

Range: {0, 2, 5}

The relation is not a function since the 0 appears more than once as an x-coordinate.

Step-by-step explanation:

The domain is the set of the x-coordinates.

The range is the set of the y-coordinates.

If any value appears more than once as an x-coordinate, it is not a function.

Domain: {0, 2, 5}

+x. +x

-30. -30

X=-4
The answer is -4

The solution to the equation 6 - x = 5x + 30 is x = -4.

We have,

To solve the equation 6 - x = 5x + 30, we can start by bringing all the variables to one side and the constants to the other side of the equation. Here's the step-by-step solution:

Start with the equation: 6 - x = 5x + 30.

To eliminate the variable terms on the right side, subtract 5x from both sides of the equation:

(6 - x) - 5x = 5x + 30 - 5x.

Simplifying the left side gives: 6 - x - 5x = 30.

Combining like terms on the left side yields: 6 - 6x = 30.

Now, isolate the term with the variable.

Move the constant term (6) to the right side by subtracting it from both sides of the equation:

6 - 6x - 6 = 30 - 6.

Simplifying both sides gives: -6x = 24.

To solve for x, divide both sides of the equation by -6:

(-6x) / -6 = 24 / -6.

Simplifying gives: x = -4.

Therefore,

The solution to the equation 6 - x = 5x + 30 is x = -4.

What is the discriminant of the quadratic equation
7x^2-4x+5=0​

Answers

Answer:

[tex]\Delta=-124[/tex]

Step-by-step explanation:

The discriminant for a quadratic in standard form is given by the formula:

[tex]\Delta=b^2-4ac[/tex]

We have the equation:

[tex]7x^2-4x+5=0[/tex]

Hence, a=7; b=-4; and c=5.

Therefore, our discriminant will be:

[tex]\Delta=(-4)^2-4(7)(5)[/tex]

Evaluate. Hence, our discriminant is:

[tex]\Delta=16-140=-124[/tex]

Notes:

Since our discriminant is negative, this tells us that the quadratic has no real roots.

Answer:

-124

Step-by-step explanation:

The discriminant is given by

b^2 -4ac  where ax^2 + bx+c =0

7x^2-4x+5=0​  so a = 7 b = -4 and c = 5

( -4) ^2 - 4(7) ( 5)

We have to given that;

The expression is,

⇒ 2 (x - 3) + 9 = 3 (x + 1) + x

Now, We can simplify the expression as;

⇒ 2 (x - 3) + 9 = 3 (x + 1) + x

⇒ 2x - 6 + 9 = 3x + 3 + x

⇒ 2x + 3 = 4x + 3

⇒ 4x - 2x = 3 - 3

⇒ 2x = 0

⇒ x = 0
