Solve each equation for y (get into slope-intercept/y=mx + b form):
a) 10x + 5y = 20 b) 3x - 2y = 10 + 4x
Answer:
Step-by-step explanation:
In order to do this we need to isolate y by performing the inverse operations on the other values like so...
a) 10x + 5y = 20 ... subtract 10x on both sides
5y = 20 - 10x ... divide both sides by 5
y = 4 - 2x ... we can move the 2x to the right to make it into y = mx + b
y = -2x + 4
b) 3x - 2y = 10 + 4x ... subtract 3x on both sides
-2y = 10 + x ... divide both sides by -2
y = -5 - 0.5x ... move -0.5 to the left so it matches y = mx + b
y = -0.5x - 5

A triangle is formed by A(0,1), B(1,0), and C(2,4). If the triangle is rotated 90 degrees counterclockwise, which algebraic representation would be used? Select one:
0 (2, y) + (-1, - y)
O (, y) + (y, - 2)
0 (2,y) → ( - 1, y)
0 (2,y) → ( - y, z)
Answer:
[tex](x,y) \to (-y,x)[/tex]
Step-by-step explanation:
Given
[tex]A = (0,1)[/tex]
[tex]B = (1,0)[/tex]
[tex]C = (2,4)[/tex]
90 degrees counterclockwise rotation
Required
The algebraic representation
Let the coordinate point be [tex](x,y)[/tex]
The rule of 90 degrees counterclockwise rotation is:
[tex](x,y) \to (-y,x)[/tex]
So, we have:
[tex]A = (0,1)[/tex] [tex]\to (-1,0)[/tex]
[tex]B = (1,0)[/tex] [tex]\to (0,1)[/tex]
[tex]C = (2,4)[/tex] [tex]\to (-4,2)[/tex]
Which operation would be last when solving the inequality -5x + 9 < -6
Answer: divding both sides by -5
Step-by-step explanation:
Subtract 9 from both sides.
−5x+9−9<−6−9
−5x<−15
Step 2: Divide both sides by -5.
−5x/−5<−15/−5
x>3

Michelle’s house is 22 miles due north of Jan’s house and 30 degrees northeast of Richard’s house. Richard’s house is due east of Jan’s house. How far is it from Michelle’s house to Richard’s house?
Answer:
Michelle’s house is 44 miles to Richard’s house.
Step-by-step explanation:
The distance can be found out by using the trigonometric ratio of sine theta
Sine theta= Perpendicular/ Hypotenuse
We know the values of hypotenuse and theta
Sine 30 = 22/ Hypotenuse
Hypotenuse= 22/ sine 30
Hypotenuse= 22/0.5
Hypotenuse = 44
The hypotenuse marks the distance between Michelle’s house to Richard’s house. Due east means counter clockwise rotation from east.

A quality control engineer is testing the battery life of a new smartphone. The company is advertising that the
battery lasts 24 hours on a full-charge, but the engineer suspects that the battery life is actually less than that.
They take a random sample of 50 of these phones to see if their average battery life is significantly less than 24
hours.
Let u represent the mean battery life for this population of phones.
The question requires stating the Null and Alternative hypothesis for the scenario described :
Answer:
H0 : μ = 24
H1 : μ < 24
Step-by-step explanation:
The claim or hypothesis to be tested in a statistical problem or analysis is the alternative hypothesis. This is usually the opposite of the Null hypothesis which is the usually the initial truth until there is significant evidence provided using statistical test to prove otherwise.
The null hypothesis, H0 in the scenario above is :
H0 : μ = 24 ( average battery life is 24 hours)
The alternative hypothesis is the claim, that is. The mean battery life not up to 24 hours ;
H1 : μ < 24
Identify the volume of the hemisphere in terms of π. HELP ME PLEASE!!! THE RED IS THE ONE I GOT WRONG!
Answer:
6174π
Step-by-step explanation:
The equation for a whole sphere is 4/3 π(r)³
Given the diameter of 42, we can conclude that the radius would be 21
Next, we would plug in these variables and get 4/3 π(21)³
Simplify all of this down and you would get 12348π
Keep in mind that we are working with a hemisphere. That means that we need to take half of 12348π
Divide that by 2 and you get 6174π
Hope this helps! :)

Ted earned $4,300 from his summer internship that he plans to invest so that he can buy a used car after three years. Ted chooses a bank that offers 5.5% compounded quarterly. Can Ted buy a car that costs $4,700 after three years? Round your numbers to the nearest cent.
Answer: Yes he will be
Step-by-step explanation:
To find out if Ted can afford the car, find the future value of $4,300 in three years.
First convert the number of years and rates to quarterly values as this is the compounding period:
Term = 3 * 4 quarters = 12 quarters
Rate = 5.5% / 4 = 1.375% per quarter
Future value = Amount * ( 1 + rate) ^ term
= 4,300 * ( 1 + 1.375%)¹²
= $5,065.69
Considering that Ted makes $5,065.69 in 3 years, he will be able to buy a car that costs $4,700.
