Write a system of inequalities to describe the
shaded region.
Answers
Answer:
In Explanation.
Step-by-step explanation:
In situations like this, you want to first find the equations of the individual lines.
Let's start with the left one.
It has a negative slope of 2 while it has a y-intercept of 1
y=-2x+1
is the equation.
The other line has a slope of 3/2.
The y-intercept is not visible, so we need to use point slope form.
I chose (2,-3)
y+3=3/2(x-2)
Simplify.
y=3x/2-3-3
y=3x/2-6
so we have
y=-2x+1
and
y=[tex]\frac{3x}{2}[/tex]-6
Since both lines are solid, the signs are ≥ or ≤
The shadings intersect above both lines so the individual shadings also have to be above the line.
That means the equation is less than the "y".
y≥-2x+1
y≥[tex]\frac{3x}{2}[/tex]-6

[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.

Step-by-step explanation:
Step 1: Define Equation
y - 58 = -43
Step 2: Solve for y
Add 58 on both sides: y = 15Step 3: Check
Plug in y into the original equation to verify it's a solution.
Substitute in y: 15 - 58 = -43Subtract: -43 = -43Here we see that -43 does indeed equal -43.

a. y = 3/2x - 12
b.y=3/2x+12
c.y=2/3x-12

Answers
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

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.
Answers
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.

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?
Answers
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

A map has a scale of 288 mi to the

reality, are 2016 mi apart? How far apart in reality are
two cities that are 8 in. apart on the map?
Answers
The scale of a map is 288 miles per inch. On the map, how far away are two cities that are actually 2016 miles apart? Two cities that are 8 inches apart on a map, how far apart are they in reality?
7 miles per inch far away are two cities that are actually 2016 miles apart and 1.142 miles per inch far away the two cities that are 8 inches apart on a map.
Let us take First two cities as A and B and the next two cities as C and D.
Now,
City A and City B are separated by 288miles per inches.
In reality, the two cities are separated by 2016 miles.
[tex]=\frac{2016}{288}=7[/tex]
The scale on the map for cities A and B is: 7
The same map, however,
what would be the separation between cities C and D,
the true distance between two cities, which is 8 miles.
This issue can be resolved with a proportion.
=[tex]\frac{288}{2016}\times 8[/tex] miles
=[tex]\frac{288\times8}{2016}[/tex] miles
=1.142 miles
Therefore, on the map, 7 miles per inch far away are two cities(A and B) that are actually 2016 miles apart and 1.142 miles per inch far away the two cities(C and D) that are 8 inches apart on a map.

Vertical Angles (Vertically Opposite Angles) When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.
9x = 36
x = 36/9

∠ IYW = ∠ WAP
SO ∠ WAP = 34°
∠IWY+∠AWI = 180° ( LINEAR PAIR)
So ∠IWY = 90°
∠IWY = ∠ AWP ( vertical opposite angle)
∠ AWP = 90°
In ΔAWP
∠ AWP+∠ WAP +∠ APW = 180°
( sum of all the angle in triangle is 180°)
90°+ 34°+8Y = 180°
