Which equation represents a line which is parallel to the line 3y - 2x = -24?Submit AnswerOy= -x - 7Oy= - žx – 2Oy= {x +3Oy= x +4
Answers
ANSWER
[tex]y=\frac{2}{3}x+3[/tex]EXPLANATION
Parallel lines have the same slope. First we should rewrite the given line in the slope-intercept form by clearing y, so that we can see what is the slope:
[tex]\begin{gathered} 3y-2x=-24 \\ 3y=2x-24 \\ y=\frac{2}{3}x-8 \end{gathered}[/tex]The slope of the line is 2/3, so the slope of the parallel line must be 2/3 too. From this options, the equation with a slope of 2/3 is:

Answers
In order to determine a point that is part of the solution of the two given inequality, let's graph the two inequalities.
For both inequalities, they are already in a slope-intercept form y > mx + b where m = slope and b = the y-intercept.
For equation 1, y > x + 2, the y-intercept is 2 and slope is 1. Since the inequality is >, we will be using a broken line and the shade will be above the line.
The graph of inequality 1 is:
Moving on inequality 2, y > -2x - 7, the slope is -2 and the y-intercept is -7. Since the inequality symbol is >, we will be using a broken line on its border and the shade will be above the line.
The graph of inequality 2 is:
Combining the two graphs in one coordinate plane, we have:
The solution set of the given system of inequalities will be the common shaded area of both inequalities. There are infinite solutions for this.
We can get some coordinates from this common shaded area and this could be:
These coordinates can be (-3, 2), (-4, 3), (-2, 4), or (-2, 2).
We can also infer from the graph that the value of x is infinite however, the value of y must be greater than -1.

Answers
Given:
Mikaela has been tracking her basketball stats for the last week.
We need to write a linear equation with the variable t for time
Let the equation has the form: y = m * t + b
Where y is the number of baskets she has made
She started shooting hoops today having already made 3200 baskets this
week.
so, at t = 0 , y = 3200
so, the value of b = 3200
We will find the value of m using the given table:
start 3200
10 min 3225
20 min 3250
30 min 3275
40 min 3300
So, the value of m = (3250 - 3225)/(20 - 10) = 25/10 = 2.5
So, the equation will be:
[tex]y=2.5t+3200[/tex]Now, we will find how many baskets will she have made if
she continues for one hour today?
So, we will substitute with t = 60 min into the last equation
So,
[tex]y=2.5\cdot60+3200=3350[/tex]So, she will make 3350 baskets
What is the conjugate of −1−5i?

the conjugate of the above complex number
A complex number is in the form: a + bi
The conjugate of the complex number is a - bi
When the complex number is -1 - 5i, where a = -1, b = -5i
The conjugate will negate the value of b
a will be -1 while b = -(-5i) = 5i
The conjugate will be -1 + 5i

The denominators are:
4 and 6

A pitcher has the ability to throw a baseball at 95 mph.a. How fast is the speed in ft/s? b. How long does the hitter have to make a decision about swinging at the ball if the plate and the mound are sepa- rated by 60 ft? c. If the batter wanted a full second to make a decision, what would the speed in mph have to be?
Answers
Speed = 95 miles per hour
a. to express it in feet per second
1 mile = 5280 ft
1 hour = 3600 seconds
(95 x 5280 )/3600 = 139.33 ft/s
b. Speed = distance / time
Time = Distance / speed
Distance = 60ft
Time = 60ft / 139.33 ft /s = 0.43 seconds
c.
speed= distance / time
S = 60 ft / 1 sec = 60 ft/s

80 mililiters of the 10% solution
120 mililiters of the 30% solution
Explanation:
let the amount of solution for the 10% = x
let the amount of solution for the 30% = y
The sum of the amount for the mixture of 10% solution and amount for the 30% solution = 200 mililiters
x + y = 200 ...(1)
In terms of fraction for each solution:
fraction of the 10% solution + fraction of the 30% solution = fraction of the mixture
percentage of the solution of the mixture = 22%
fraction of the 10% solution = 10% (x) = 0.1(x) = 0.1x
fraction of the 30% solution = 30%(y) = 0.3(y) = 0.3y
fraction of the mixture = 22%(200) = 0.22(200)
substitute the above into the equation for fraction:
0.1x + 0.3y = 0.22(200)
0.1x + 0.3y = 44 ...(2)
combine both equatons:
x + y = 200 ...(1)
0.1x + 0.3y = 44 ...(2)
Using substitution method to solve the equations:
from equation 1, let's make x the subject of formula:
x = 200 - y
substitute for x in equation (2):
0.1(200 - y) + 0.3y = 44
20 - 0.1y + 0.3y = 44
20 + 0.2y = 44
0.2y = 44 - 20
0.2y = 24
divide both sides by 0.2:
0.2y/0.2 = 24/0.2
y = 120
sustitute for y in equation (1):
x + 120 = 200
x = 200 - 120
x = 80
Hence, James must mix:
80 mililiters of the 10% solution
120 mililiters of the 30% solution
The average gas price in 2013 was $3.34. The probability that a gas price was less than $2.90 was 20%. What would be the standard deviation?
Answers
We know that the probability in a normal distribution can be obtained by the z score, the z score is given as:
[tex]Z=\frac{x-\mu}{\sigma}[/tex]where mu is the mean and sigma is the standard deviation. In this case we have:
[tex]\begin{gathered} P(X<2.9)=0.2 \\ P(Z<\frac{2.9-3.34}{\sigma})=0.2 \\ P(Z<\frac{-0.44}{\sigma})=0.2 \end{gathered}[/tex]Now, to have 20% (that is 0.2) we need that the z score to be -0.842, then we have:
[tex]\begin{gathered} -\frac{0.44}{\sigma}=-0.842 \\ \sigma=\frac{-0.44}{-0.842} \\ \sigma=0.52256532 \end{gathered}[/tex]Therefore the standard deviation is $0.52

Given:
Any single line can have more than one point-slope equation.
To check: It is true or false.
Explanation:
The standard form of a point-slope equation is,
[tex]y=mx+c[/tex]Where m is the slope of the line and c is the y-intercept.
Here, (x, y) is any one point of the line.
The slope of the line is the same for every point of the line. Also, there must be a single y-intercept since the straight line has a linear function.
Any single line can have more than one point-slope equation if we change points simultaneously.

At every point of the line, we can write the point-slope eq
QRST is a rectangle. Find the value of x and the length of each diagonal. QS = 5x + 12 and RT = 6x – 2

[tex]QS=5x+12=5\cdot14+12=70+12=82[/tex]Answer: the lengths of the diagonals QS and RT is 82.
The value of x is 14 and the length of each diagonal would be 82 units.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that QRST is a rectangle.
We have to determine the value of x and the length of each diagonal.
QS = 5x + 12 and RT = 6x – 2
Because a rectangle's two diagonals will be the same length, we may write:
QS = RT
5x + 12 = 6x – 2
Rearrange the terms in the above equation,
6x - 5x = 12 + 2
x = 14
The value of x is 14.
So, QS = 5(14) + 12 and RT = 6(14) – 2
So, QS = RT = 82
Therefore, the length of each diagonal would be 82 units.
