Answer:

y = -5/2x + 7

Step-by-step explanation:

The line is perpendicular, so mx is the reciprocal of 2/5 which would be -5/2. Then you plug that and (4, -3) into the equation y = mx + b, which will come out as -3 = (-5/2)(4) + b. Multiply mx to get -3 = -10 + b. Add 10 to both sides to get 7 = b. Plug in mx and b into the equation and you have your answer.

Point R divides in the ratio 1 : 3. If the x-coordinate of R is -1 and the x-coordinate of P is -3, what is the x-coordinate of
ollegr [7]

<em><u>Question:</u></em>

Point R divides in the ratio 1 : 3. If the x-coordinate of R is -1 and the x-coordinate of P is -3, what is the x-coordinate of Q?

<em><u>Answer:</u></em>

x-coordinate of Q is 5

<em><u>Solution:</u></em>

Given that,

Point R divides in the ratio 1 : 3

Which means,

Point R divides the line segment PQ internally

The x-coordinate of the point which divides the line segment in ration m:n internally is given as:

x=(\frac{mx_{2}+nx_{1}}{m+n} )

Where,

x = x-coordinate of point dividing the segment R = -1

x_1 = x-coordinate of P = -3

x_2 = x-coordinate of Q = ?

m : n = 1 : 3

m = 1

n = 3

Therefore,

-1 = \frac{1 \times x_2 + 3 \times -3}{1+3}\\\\-1 = \frac{x_2 -9}{4}\\\\x_2 - 9 = -4\\\\x_2 = 9 - 4\\\\x_2 = 5

Thus x-coordinate of Q is 5

Mai has a jar of quarters and dimes. She takes at least 10 coins out of the jar and has less than $2.00.
Rama09 [41]

Answer:

?

Step-by-step explanation:

Problem 1

Sketch or describe the figure in Step 4 and Step 15.

Pattern of small squares. Step 1 has 1 square. Step 2 has 4 squares, 2 by 2 with bottom left square moved to top right corner. Step 3 has 9 squares, 3 by 3 with bottom left moved to top right corner.

How many small squares will there be in each of these steps?

Write an equation to represent the relationship between the step number, , and the number of small squares, , in each step.

Explain how your equation relates to the pattern.

Problem 2

Which expression represents the relationship between the step number  and the total number of small squares in the pattern?

A pattern of small squares. Step 1 has 0 squares. Step 3 has 3 squares: 2 by 2 but missing the lower right square. Step 3 has 8 squares: 3 by 3 but missing the lower right square.

A:

B:

C:

D:

Problem 3

Each figure is composed of large squares and small squares. The side length of the large square is . Write an expression for the area of the shaded part of each figure.

Figure A

Large square with 1 by 1 small squares removed from each corner.

Figure B

2 large squares side by side. On the side of the right square, there are 2 small squares stacked vertically, each with dimensions 2 by 2.

Problem 4

Here are a few pairs of positive numbers whose difference is 5.

Find the product of each pair of numbers. Then, plot some points to show the relationship between the first number and the product.

Blank coordinate plane. Horizontal axis, first number, 0 to 10. Vertical axis, product, 0 to 100 by 10s.

Is the relationship between the first number and the product exponential? Explain how you know.

(From Algebra1, Unit 6, Lesson 1.)

Problem 5

Here are some lengths and widths of a rectangle whose perimeter is 20 meters.

Complete the table. What do you notice about the areas?

length

(meters) width

(meters) area

(square meters)

Without calculating, predict whether the area of the rectangle will be greater or less than 25 square meters if the length is 5.25 meters.

On the coordinate plane, plot the points for length and area from your table.

Do the values change in a linear way? Do they change in an exponential way?

A blank graph, origin O, with a grid.

Problem 6

Here is a pattern of dots.

Four figures, labeled step 0 through 3. Step 0, row with 1 dot. Step 1, row with 2 dots. Step 2, row with 2 dots above row with 3 dots. Step 3, 2 rows of 3 dots above row with 4 dots.

Complete the table.

Problem 7

Mai has a jar of quarters and dimes. She takes at least 10 coins out of the jar and has less than $2.00.

Write a system of inequalities that represents the number of quarters, , and the number of dimes, , that Mai could have.

Is it possible that Mai has each of the following combinations of coins? If so, explain or show how you know. If not, state which constraint—the amount of money or the number of coins—it does not meet.

3 quarters and 12 dimes

4 quarters and 10 dimes

2 quarters and 5 dimes

(From Algebra1, Unit 2, Lesson 25.)

Problem 8

A stadium can seat 63,026 people. For each game, the amount of money that the organization brings in through ticket sales is a function of the number of people, , in attendance.

If each ticket costs $30.00, find the domain and range of this function.

1. In a game, if you roll a 6 on a 6-sided number cube, you lose a turn.
Mademuasel [1]
A) 1/6
B) 5/6
C) 1
D) 20

Explanation:

A) There is one 6 on a 6-sided die, out of 6 numbers.

B) There are 5 numbers that are not 6 on a 6 sided die, out of 6 numbers.

C) P( 6 or ~6) = P(6) + P(~6) = 1/6 + 5/6 = 6/6 = 1

D) 1/6(120) = 120/6 = 20
