Parallel lines have the same slope so the equation will have the same slope. The y-coordinate is the new y-intercept, so the equation is y = 3x + 8
Hope this helps
Answer:
y = 3x + 5
Step-by-step explanation:
Line y = 3x - 8; slope = 3
Parallel lines, slope is the same so slope of the line that parallel to the line y = 3x - 8 is also 3
Passing thru (1,8)
y - 8 = 3(x - 1)
y - 8 = 3x - 3
y = 3x + 5

Two similar triangles are shown. Triangle RST was , then dilated, to create triangle ZXY. plzzzzzz
Answer: Translated (Option C)
Step-by-step explanation:
Two similar triangles RST was then dilated, to create triangle ZXY.
For dilation, translation should be done.
What is dilation?Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape.
As, ΔRST was dilated to form ΔZXY.
But, this can be done by translation , to create ΔZXY
The following information:
Since Triangle ΔZXY is slightly higher and to the right of triangle ΔRST.
So it should be translated.
so, that it could be dilated for ΔZXY.

What are the slope and the y-intercept of the line shown in the graph
The y-intercept is the y value when x = 0, or (0 , y)

The perimeter of a rectangle is 44. The length is 5 less than double the width. Find the dimensions
Length: 2w - 5
Width: w
2(2w - 5) + 2w = 44
Distribute:
4w - 10 + 2w = 44
Combine like terms:
6w - 10 = 44
Move 10 to the other side:
6w = 54
Divide by 6:
w = 9, which is the width. That means that 13 is the length.
To find the dimensions of the rectangle, we can set up a system of equations and solve for the width and length. By using the formula for the perimeter of a rectangle, we can find the values of the dimensions.
Explanation:To solve this problem, we can set up a system of equations based on the given information. Let's assume that the width of the rectangle is 'w', and since the length is 5 less than double the width, we can express the length as '2w - 5'. The perimeter of a rectangle is given by the formula 2(length + width), so we can use this formula to set up an equation:
2(2w - 5 + w) = 44
Simplifying this equation, we get 6w - 10 = 44. Solving for 'w', we find w = 9. Substituting this value back into the expression for the length, we find the length is 13.
Therefore, the dimensions of the rectangle are width = 9 and length = 13.

12.5° or 13° depends how your teacher wants the answer. 4x-2 = 48
4x = 50
X = 12.5°
From the diagram, since[tex]$\angle AHK$[/tex] and [tex]$\angle EHB$[/tex] are supplementary angles, we have [tex]m\angle AHK + m\angle EHB = 180^\circ$.[/tex]
Substituting in the values that are given, we get [tex]48^\circ + (4x-2)^\circ = 180^\circ$.[/tex] Solving for x, we get [tex]$x = \boxed{33.5}$.[/tex]
From the diagram, we see that angles [tex]$\angle AHK$[/tex] and [tex]$\angle EHB$[/tex] are supplementary angles.
Therefore, we have the equation [tex]m\angle AHK + m\angle EHB = 180^\circ$.[/tex]
Substituting in the values that are given, we get [tex]48^\circ + (4x-2)^\circ = 180^\circ$.[/tex]
Simplifying both sides of the equation, we get [tex]4x-2 + 48 = 180$.[/tex]
Subtracting 46 from both sides of the equation, we get [tex]4x = 134$.[/tex]
Dividing both sides of the equation by 4, we get

Iliana’s math grade increased from 65 to 86. Fiona’s math grade increased from 70 to 80. What is the difference, rounded to the nearest whole number, between the approximate percent increases?
Answer:
18 points
Step-by-step explanation:
We first need to find the percent increase for both Iliana an Fiona.
To do so, we take the absolute value of difference (the score increase) and we compare/divide it by the original score they had.
So, for Iliana, we have a starting score of 65 and an increase of 21 (86-65).
Her percent of increase is 21/65 = 32.3%
For Fiona, she went from 70 and had a 10 points increase (80-70).
Her percent of increase is 10/70 = 14.3%
The difference between the two percent of increase is 18 points (32.3 - 14.3)
Answer with Step-by-step explanation:
Percentage increase in score is calculated by the formula:
[tex]\dfrac{New\ score-Old\ score}{Old\ score}\times 100[/tex]
Iliana’s math grade increased from 65 to 86.
Percentage increase in Iliana's score is:
[tex]\dfrac{86-65}{65}\times 100[/tex]
=[tex]\dfrac{21}{65}\times 100[/tex]
=32.31%
Fiona’s math grade increased from 70 to 80.
Percentage increase in Fiona's score is:
[tex]\dfrac{80-70}{70}\times 100[/tex]
=[tex]\dfrac{10}{70}\times 100[/tex]
=14.28%
Difference between percentage increases=32.31%-14.28%
= 18.03%
Hence, difference, rounded to the nearest whole number, between the approximate percent increases is:
18%
Jenna was alone in the house for two months. To pass the time, she read 216 comics and 150 novels. How many books did she read? She went to her friends Emilia’s house for 5 hours and went shopping for 1 hour. How many hours was she gone?
Answer:
She read 366 books and she was gone for 6 hours.
Step-by-step explanation:
216+150=366
5+1=6
Final answer:
Jenna read a total of 366 books, combining both the comics and novels. She was gone for 6 hours in total when visiting her friend Emilia and going shopping.
Explanation:
Jenna read a total of 216 comics and 150 novels. To find how many books she read, you simply add these two numbers together:
216 comics
+ 150 novels
216 + 150 = 366 books.
For the second part of the question, Jenna spent 5 hours at Emilia's house and went shopping for 1 hour. To find out how many hours she was gone, you add the two durations of time:
5 hours at Emilia's house
+ 1 hour shopping
5 + 1 = 6 hours gone.

Step-by-step explanation:
To find the term needed, use the binomial formula.
[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]
Let 8x = 2ab, a is by default x, which leaves us with:
8x = 2xb
8 = 2b
b = 4
And by the binomial formula add [tex]b^2[/tex] to both sides, namely 16.
[tex]x^2 + 8x + 16 = 17 + 16\\(x+4)^2 = 33[/tex]
which graph shows the solution to the inequality
|x+3| ≥ 2?
Answer:
2nd number line
Step-by-step explanation:
When there is an absolute value inequality of the form |x+a| ≥ b,
We can say that the solution set (in a number line) would be:
we take the point x = -athen we go b units in both directions (left and right)start from those 2 points and draw arrows in both directions (left & right)Keeping these points in mind,
|x+3| ≥ 2
we start from x = -3
we go 2 units left and right, so we arrive at x = -5 and x = -1
then we draw arrows to both sides
looking at the choices, we see 2nd answer choices (graph) portrays it correctly.

Determine the solution, if any, to the system of equations below.
8x - 2y = 1
-4x + y = 3
Answer:
DNE.
Step-by-step explanation:
8x - 2y = 1 ---------------------(1)
-4x+ y = 3----------------------(2)
Multiply (2) by 2
-8x +2y = 6 -----------------(3)
Add (1) to (3)
8x - 2y + (- 8x + 2y) = 1+6
8x - 2y - 8x +2y = 7
But all the terms in LHS cancel out, leaving 0.
So you get 0=7, which is not valid.
Therefore no solution exists. DNE
There is no solution to the system of equations.
Explanation:To solve the system of equations:
8x - 2y = 1
-4x + y = 3
Start by isolating a variable in either equation. Let's isolate y in the second equation by adding 4x to both sides: y = 4x + 3Substitute this expression for y in the first equation: 8x - 2(4x + 3) = 1Simplify the equation: 8x - 8x - 6 = 1Solve for x: -6 = 1.

Conditional probability is defined as:
P(A|B) = P(A∩B) / P(B)
where P(A|B) is the probability of A on the condition of B, P(A∩B) is the probability of both A and B, and P(B) is the probability of B.
Here, we want P(P|K), so:
P(P|K) = P(P∩K) / P(K)
P(P|K) = 0.019 / 0.023
P(P|K) = 0.826
