Select the correct answer. 3 A linear function has a y-intercept of -12 and a slope of 3/2. What is the equation of the line?
a. y = 3/2x - 12
b.y=3/2x+12
c.y=2/3x-12
d y=-12x-3/2
Answer:
a. y = 3/2x - 12
Step-by-step explanation:
Slope is y = mx + b
Slope or m = 3/2
y-intercept or b = -12
Substitute m for 3/2 and b for -12 then the answer would be y = 3/2x - 12
2) In A ABC , if LA = 60° , LB = 450 then find tc.
In ∆ABC,
Angle A = 60°
Angle B = 45°
To Find:The measurement of Angle C.
We know that the sum of all the interior angles of a triangle is 180°.
Explanation:Angle A + Angle B + Angle C = 180°
By putting the respected values, we get
60° + 45° + Angle C = 180°
or, 105° + Angle C = 180°
By transposition method, we get
Angle C = 180° - 105°
Angle C = 75°
Answer:The measurement of Angle C is 75°
During her senior year, Courtney took both the SAT and ACT. She scored 680 on the SAT math test and 27 on the ACT math test. Scores on the math section of the SAT vary from 200 to 800, with a mean of 528 and standard deviation of 117. Scores on the math section of the ACT vary from 1 to 36, with a mean of 20.5 and a standard deviation of 5.5.
Calculate Courtney's standardized score (z-score) on each test. Which of her two test scores was better, relatively speaking? Explain your reasoning.
Her z-scores are given as follows:
SAT: 1.30.ACT: Z = 1.18.Due to the higher z-score, she was relatively better on the SAT.
What is the z-score formula?The z-score of a measure X of a distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.For the SAT test, the parameters are given as follows:
[tex]X = 680, \mu = 528, \sigma = 117[/tex]
Hence her z-score is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (680 - 528)/117
Z = 1.30.
For the ACT test, the parameters are given as follows:
[tex]X = 27, \mu = 20.5, \sigma = 5.5[/tex]
Hence her z-score is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (27 - 20.5)/5.5
Z = 1.18.
Due to the higher z-score, she was relatively better on the SAT.

2(2 – 2x) = –3x A. –4 B. 4 C. 6 D. 0
Answer:
[tex]x = 4[/tex]
Step-by-step explanation:
Let's solve:
[tex]2(2−2x)=−3x[/tex]
Step 1: Simplify both sides of the equation.
[tex]2(2−2x)=−3x \\ (2)(2)+(2)(−2x)=−3x(Distribute) \\ 4+−4x=−3x \\ −4x+4=−3x[/tex]
Step 2: Add 3x to both sides.
[tex]−4x+4+3x=−3x+3x \\ −x+4=0[/tex]
Step 3: Subtract 4 from both sides.
[tex]−x+4−4=0−4 \\ −x=−4[/tex]
Step 4: Divide both sides by -1.
[tex] \frac{ - x}{ - 1} = \frac{ - 4}{ - 1} [/tex]
Therefore, the answer will be x = 4.

Weight is a measure of force affected by gravity. The Moon’s gravity is less than Earth’s gravity, so objects weigh less on the Moon than on Earth.
How much do you think a cat will weigh on the Moon? Explain your reasoning.

Answer:
about 1.5 pounds
Step-by-step explanation:
The moon's gravity is about 1/6 that of Earth, so a 9-lb cat would weigh about 9/6 = 1.5 pounds on the moon.

An airplane is preparing to land at an airport. It is46,400 feet above the ground and is descending at the rate of3,100 feet per minute. At the same airport, another airplane is taking off and will ascend at the rate of 2,700 feet per minute. When will the two airplanes be at the same altitude and what will that altitude be?
The time when the two airplanes would have the same altitude is 8 minutes. The altitude would be 21,600 feet.
What is the altitude?The equation that can be used to represent the altitude of the descending plane is: feet above the ground - (rate of descent x number of minutes)
46,400 - (3100 x t)
The equation that can be used to represent the altitude of the ascending plane is: rate of ascent x number of minutes
2700 x t
Where t is the number of minutes
When both airplanes are of the same altitude, the above equations will be equal: 2700t = 46,400 - 3100t
In order to determine the value of t, take the following steps:
Combine similar terms: 2,700t + 3,100t = 46,400
Add similar terms : 5,800t = 46,400
Divide both sides by 5,800 : t = 46,400 / 5,800
t = 8 minutes
Altitude = 2700 x 8 = 21,600 feet

Answer:

Step-by-step explanation:
First we distribute 13 to x and 15. That gives us 13x+15x=3. Now we add 13x and 15x, that gives us 28x=3. Now we divide by 28 on both sides. That gives us x=0.107
