Answer:

The transformation is (y,-x)

Step-by-step explanation:

To know the mapping notation, we need to know the coordinates of the image and the pre-image

For the pre-image, we have;

A(3,8)

B(6,8)

C(6,2)

For the image, we have

A’( 8,-3)

B’ (8,-6)

C’ (2,-6)

So let us try and get the transformation from the coordinates

We can see that this is;

(x,y) to (y,-x)

Step-by-step explanation:

y=3x+1, y= -3x+7

y=1,X=1

X+y=10,2x+2y=20

X=5, y=5

Answer:

It's 1/6

Step-by-step explanation:

all you have to do is multiply the answer by 1/3 so 1/3 times 1/2 equals 1/6 so your answer is 1/6

Example 1: One-Step Inequalities

A bag of candy is split between us and our little brother. The bag says it has at most 28 pieces of candy in it. There are 15 candies in our bag, and x candies in our brother's bag, and we have to make sure he doesn't have more than us (of course). We can write an inequality expressing the number of candies in the bags.

We know that our bag has 15 candies.

We know that his bag has x candies.

We know that up to 28 candies were split between both bags, no more.

Since we know that x + 15 can't be more than 28, it must be less than or equal to 28. x + 15 ≤ 28

Now that we have an inequality expressing our candy, we solve for x. To do that, we subtract 15 from both sides.

x + 15 ≤ 28

x + 15 – 15 ≤ 28 – 15

x ≤ 13

Sweet, literally. Our brother has 13 or fewer pieces of candy, so no way does he have more candy than us. Until, in a moment of weakness (er, kindness) we share a few of our pieces with him. Now it's even sweeter.

Example 2: Two-Step Inequalities

A candy store owner saw us share our candy with our brother and was so impressed he gave us a $30.00 gift card. Tax free even! We decide to buy a giant candy bar for $13.00 and then some lollipops with the remaining money. If each lollipop is $0.90, we can write and solve an inequality expressing how many lollipops we can buy.

We know that the amount we spend needs to be less than or equal to $30.00.

We know we want to buy x lollipops.

We know that each lollipop is $0.90, so the total cost of the lollipops is $0.90x.

We know the candy bar costs $13.00.

So the total cost of the candy is $13 + $0.90x, and this needs to be less than or equal to $30.00. 13 + 0.90x ≤ 30

Now we solve for x, which is the number of lollipops we can buy. We want to get x by itself, so start by subtracting 13 from both sides.

13 + 0.90x ≤ 30

13 + 0.90x – 13 ≤ 30 – 13

0.9x ≤ 17

Divide both sides by 0.9 to finish up. We recommend nabbing a calculator for this part.

We need to buy less than 18.89 lollipops, so we can buy 18 whole lollipops and have some change to spare.

Answer:

The answer is A.

Answer:

if it was 50% off the cost would be $145.64

Step-by-step explanation:

291.29 / 1/2= 145.64

50% = 1/2

Answer: y = -1/3x + 17/3

Step-by-step explanation:

Hey there! I will be showing and giving the formula/steps to solve this problem. If there are any questions then feel free to ask in the comments.

Formula: y = mx + b

Step 1 - Find M

m = (6 - 4) / (-1 - 5) = -2/6 = -1/3

The m is the slope.

Step 2 - Use (5, 4) to find point B

y = -1/3x + b

4 = 1/3 * 5 + b

b = 17/3

Answer: y = -1/3x + 17/3

You will plugin 4 for y and b is the intercept.

Answer:

C

Step-by-step explanation:

The system of equations [tex]y = -16x^2+60x+3\\y=-16x^+55x+2.5[/tex]  models the projectile motion of the two balls. option C is correct.

Laura and Kennedy are at softball practice. Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second. Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second. The projectile equations is to be determined.

Projectile motion is the movement of an entity projected into the space. After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory.

Projectile equation = vertical motion + horizontal motion + intercept.

Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second.
y = gx²/2 + v*x + 3
y = -32/2 * x² + 60x + 3
y = -16x² + 60x + 3

Similarly, Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second.
y = -16x² + 55x + 2.5

Thus, the system of equations [tex]y = -16x^2+60x+3\\y=-16x^+55x+2.5[/tex]  models the projectile motion of the two balls. option C is correct.

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 7) and (x₂, y₂ ) = (2, 5) ← 2 points on the line

Answer:

y = [tex]-\frac{1}{3}x-\frac{2}{3}[/tex]

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

m = Slope of the line

b = y-intercept

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Since, the given line passes through two points (-5, 1) and (4, -2)

Slope of the line 'm' = [tex]\frac{1+2}{-5-4}[/tex] = [tex]-\frac{1}{3}[/tex]

Equation of the line will be,

y = [tex]-\frac{1}{3}x+b[/tex]

Since, this line passes through (4, -2),

-2 = [tex]-\frac{4}{3}+b[/tex]

b = [tex]\frac{4}{3}-2[/tex]

b = [tex]-\frac{2}{3}[/tex]

Therefore, equation of the line will be,

y = [tex]-\frac{1}{3}x-\frac{2}{3}[/tex]
