Answer:
2y - 6
Step-by-step explanation:
5y - 3(y + 2)
distribute
5y + (-3 * y) + (-3 * 2)
simplify
5y -3y + ( -3 * 2)

for the linear function f, the graph of y=f(x) in the xy-plane passes through the points (0,2) and (9,9). what is the slope of y=f(x)?
Answer:
[tex]slope = \frac{(y _{2} - y _{1})}{(x _{2} - x _{1})} \\ = \frac{(9 - 2)}{(9 - 0)} \\ = \frac{7}{9} \\ hence \: slope \: is \: \frac{7}{9} [/tex]
You have a square that has a side length of $1$ centimeter. Each minute, $2$ centimeters are added to the side length. After $10$ minutes, what will be the difference between the area of the last square and the area of the initial square in square centimeters (do not include the units in your answer)?
Answer:
Difference in area of the last square and the initial square = 440 cm²
Step-by-step explanation:
Length of the side of a square = 1 cm
Area of the square = (side)² = 1 cm²
Addition of side length every minute = 2 cm
After x minutes length of each side of the square = (1 + 2x) cm
If x = 10 minutes
Length of each side of the square = [1 + 2(10)]
= 21 cm
Area of the square after 10 minutes = (21)²
= 441 cm²
Therefore, difference in area of the last square and area of the initial square
= 441 - 1
= 440 cm²

Write the equation for the line that has the given slope and contains the given point.
slope = −2
passes through ( 3 , 1 )
Answer:
Step-by-step explanation:
y = mx + b
m = slope
b = y intercept
y and x in the equation represent the coordinate points (3,1)
so substituting,
y = -2x + b
1 = -2(3) + b
1 = -6 + b
b = 7
so the final equation is,
y = -2x + 7

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). The one-time fixed costs will total $53,533. The variable costs will be $12.50 per book. The publisher will sell the finished product to bookstores at a price of $24.25 per book. How many books must the publisher produce and sell so that the production costs will equal the money from sales?
9514 1404 393
Answer:
4,556
Step-by-step explanation:
Revenue from the sale of n books is ...
R = 24.25n
Production cost for n books is ...
C = 53533 +12.50n
These are equal for ...
24.25n = 53533 +12.50n
11.75n = 53533
n = 53533/11.75 = 4556
The publisher must produce 4556 books so sales will equal production cost.

Mrs. Poster's class is divided into three groups of students. Each group has 3 girls and 2 boys, Which expression could she use to find the total number of students in the class?
O 3+(2+3)
(3 X 2) + 3
O 3x (2+3)
(32)
Answer:
3 X (2+3)
Step-by-step explanation:
If we have five students (3 girls and 2 boys), and three groups, we can use the expression 3 X (2+3), which concludes three groups times five students (in each group), which will give us our total of 15 students.
Kelsea and Landon are playing in a park standing 100 feet away from each other. They both see a bird flying above them. The angles of elevation from each person to the bird are shown. How high is the bird from the ground? Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
use an ASA triangle with law of sine
since we know that 180 = 20 +45 + C .. solve for C = 115°
now use law of sines c/ sin(C) = b/sin(B) .. and solve for b
Sin(20)*100/sin(115) = b
b = 37.73774 ft
that's the hypotenuse of the 45 triangle
SOH CAH TOA to remember how trig functions fit
use b*Cos(45) = adj
26.6846 = adj
The bird is 26.7 ft. from the ground

A sample of n = 4 scores has SS = 48. What is the estimated standard error for this sample? Group of answer choices
Answer:
2
Step-by-step explanation:
We have
n = 4 scores
SS = 48
For this question, we are required to find the estimated standard error
To get this, we first solve for the variance
S² = SS/n-1
= 48/4-1
= 48/3
= 16
Then S² = 16
S = √16
S = 4
Then the estimated standard error is given by:
S/√n
= 4/√4
= 4/2
= 2.
The estimated standard error is 2.
