Graph this function:
y + 1 = 2(x + 3)
Click to select points on the graph.

Answers

Answer 1

Answer:

use points (0,5) and (1,7)

see below for graph

Step-by-step explanation:

First, we'll turn the equation from point slope form (y-y1=m(x-x1)) into slope intercept form (y=mx+b)

y+1=2(x+3)

do the distributive property

y+1=2x+6

subtract 1 from both sides

y=2x+5

We'll need two points to graph the line.

You can subsitute x or y as any number you like and solve the equation.

For example:

if x=0:

y=2(0)+5

y=5

so the point would be (0,5)

and if x=1

y=2(1)+5

y=2+5

y=7

point: (1,7)

Use the points (0,5) and (1,7)

See below if you would like to see how it looks like on a graph.

Hope this helps!

At a bake sale, David bought 3 tarts and 5 cookies, and paid $10.50. At the same prices, Lisa bought 4 tarts and 8 cookies, and paid $14.80. What was the price of a tart and the price of a cookie?

Answers

T = Tarts
C = Cookies

David:
3T + 5C = 10.50

Lisa:
4T + 8C = 14.80

Setup as system of equations and use substitution or elimination

Elimination is easier for this case but either will give you the right answer I worked it both ways

T= cost of tarts = $2.50
C= cost of cookies = $0.60

You include 1/2 tablespoon of essential oils in a solution for every 12
tablespoons of jojoba oil. What is the value of the ratio of essential oils to
jojoba oil?

Answers

The required ratio of essential oils to jojoba oil is 1:24.

Given that,
You include 1/2 tablespoon of essential oils in a solution for every 12

tablespoons of jojoba oil.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
tablespoon of essential oils = 1/2
tablespoons of jojoba oil = 12
Ratio = [1 / 2] / 12
Ratio = 1 / [2 × 12]
Ratio = 1 / 24

Thus, the required ratio of essential oils to jojoba oil is 1:24.

Which system of linear equations has the ordered pair (-2,8) as its solution?
Oy - 2x = 12 and x - 2y = -18
O x – 2y = 12 and y - 2x = -18
Oy + 2x = 12 and x + 2y = -18
O x + 2y = 12 and y + 2x = -18

Answers

Answer:

The solution to the system of linear equations is:

(x, y) = (-2, 8)

Hence, y - 2x = 12 and x - 2y = -18  has the ordered pair (-2,8) as its solution. Thus, option A is correct.

Step-by-step explanation:

Checking the first system of equations

y - 2x = 12

x - 2y = -18

solving the first system of equations

[tex]\begin{bmatrix}y-2x=12\\ x-2y=-18\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}y-2x=12\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y-4x=24[/tex]

[tex]\begin{bmatrix}2y-4x=24\\ -2y+x=-18\end{bmatrix}[/tex]

adding the equations

[tex]-2y+x=-18[/tex]

[tex]+[/tex]

[tex]\underline{2y-4x=24}[/tex]

[tex]-3x=6[/tex]

[tex]\begin{bmatrix}2y-4x=24\\ -3x=6\end{bmatrix}[/tex]

solving -3x=6 for x

[tex]-3x=6[/tex]

Divide both sides by -3

[tex]\frac{-3x}{-3}=\frac{6}{-3}[/tex]

Simplify

[tex]x=-2[/tex]

[tex]\mathrm{For\:}2y-4x=24\mathrm{\:plug\:in\:}x=-2[/tex]

[tex]2y-4\left(-2\right)=24[/tex]

[tex]2y+8=24[/tex]

Subtract 8 from both sides

[tex]2y+8-8=24-8[/tex]

Simplify

[tex]2y=16[/tex]

Divide both sides by 2

[tex]\frac{2y}{2}=\frac{16}{2}[/tex]

Simplify

[tex]y=8[/tex]

Therefore, the solution to the system of linear equations is:

(x, y) = (-2, 8)

Hence, y - 2x = 12 and x - 2y = -18  has the ordered pair (-2,8) as its solution. Thus, option A is correct.

True False Read the passage.The Ride of His LifeWhen Jesse Senko was 12 years old, he had an experience that literally changed his life. Senko was snorkeling while on vacation in the Cayman Islands with his family when a large sea turtle swam near him. Senko naturally did what any 12-year-old boy would do and decided to grab the turtle and go for a ride. That turtle ride, in some ways, has never ended. People find their passions in many different ways. Senko found his passion while riding on the back of a turtle when he was just 12 years old.Today, Senko is a conservation scientist at Arizona State University. He focuses his research and lifes work on marine resource sustainability. Can you guess what that includes? If you guessed sea turtles, you would be correct. In college, Senko majored in fisheries and wildlife science, and he also received a Master of Science degree in wildlife ecology. Much of the focus of his work is on saving endangered sea turtles.Sea turtles help keep the ocean healthy, and thus their well-being affects the entire ecosystem. They provide a natural regulatory system for the environment. For example, sea turtles eat seagrass, which helps it grow properly, and their unhatched eggs provide nutrients for plant life to keep beaches healthy. Sea turtles also provide a home for small animals that attach to their shells.Sea turtles are endangered because fishermen inadvertently catch them in their nets, which can cause the turtles irreparable harm. Senko came up with the idea to create solar-powered fishing nets so fishermen can readily see when they accidentally catch a sea turtle. Because the lights are solar powered, the fishermen do not have to maintain the lights or change the batteries. This technology has resulted in a 65 percent reduction in sea turtle catches thus far. Senkos goal is a 100 percent reduction.In "The Ride of His Life," what is the author's viewpoint toward Senkos career?Senko is overly protective of sea turtles.Senko is passionate about working with marine wildlife.Senko is on the cutting edge of modern technology.Senko is an avid fisherman who wants to help save wildlife.
