Answer:
Firstly Substitute y=2x-5 into 5x-4y=-10
This will be 5x-4(2x-5)=10 now solve for x
5x-8x+20=-10
-3x=-30
X=10
Now sub x as 10 into the second equation y=2x-5
Y=2(10)-5
Y=15

A good trick to have up your sleeve is to just memorize that the equation of a like is (y - y1) = m * (x - x1).
This equation describes a point that passes through (x1, y1) with a slope m. This point (x1, y1) does not have to be on the y-axis. Also, since the question told us they want m = slope = -1/4, all we have to do is plug stuff in.
(y - y1) = m * (x - x1) => (y - 4) = -1/4 * (x - 4), or answer D. Also note that the normal ‘x’ and ‘y’ here are variables. We can solve this equation for ‘y’ to give a more traditional format: y = -1/4x + 5.

Henry worked for 8 days, Jack worked for 9.5 days while Steffi worked for 6.5 days to complete a project. If the amount earned for the project completion was shared among them in the ratio of the number of days each one had worked, find the ratio in which the amount was shared.
Answers
Answer:
The ratio in which the amount is shared is 16:19:13
Step-by-step explanation:
The given parameters are;
The number of days Henry worked = 8 days
The number of days Jack worked = 9.5 days
The number of days Steffi worked = 6.5 days
The sharing formula for the amount earned for the project = The ratio of the number of days worked by each one
The total number of days worked by all three = 8 days + 9.5 days + 6.5 days = 24 days
The fraction of the total number of days Henry worked = (8 days)/(24 days) = 1/3 = 16/48
The fraction of the total number of days Jack worked = (9.5 days)/(24 days) = 19/48
The fraction of the total number of days Steffi worked = (6.5 days)/(24 days) = 13/48
Therefore. the ratio in which the amount is shared = 16:19:13 (which is the same as the ratio of the number of days worked)

* A helicopter's altitude changes by – 28 ft in 3 s.
What is the average change in the helicopter's altitude
each second? Show your work.
Answers
Answer:
-9.33 ft per second
Step-by-step explanation:
To calculate this, you just have to divide -28 by 3. When doing this, it will give the change per second or for every 1 second.
-28/3 = -9.33
Therefore, the average change in the helicopter's altitude each second is -9.33 ft.

Find the leg of an isosceles right triangle when the hypotenuse measures 8
Answers
Answer:
4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
ratio of leg to hypotenuse in a 45-45-90° triangle is 1 : [tex]\sqrt{2}[/tex]
we can use this proportion to solve the problem:
let 'x' = leg
x/8 = 1/[tex]\sqrt{2}[/tex]
cross-multiply:
[tex]\sqrt{2}[/tex] x = 8
x = 8 / [tex]\sqrt{2}[/tex]
if you multiply top and bottom by [tex]\sqrt{2}[/tex] you will get 4[tex]\sqrt{2}[/tex]

Actually Welcome to the Concept of the Parallel lines.
To make them parallel ,just equate them.
5x = 3x + 60
===> 5x - 3x = 60
===> 2x = 60
.hence, x = 30
====> x = 30
The value of x for which A || B is 15° as they are pair of alternate angles.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
Given, are two alternate angles 5x and 3x + 60, the lines A and B will be parallel if the sum of these two angles is 180°.
∴ 5x + 3x + 60 = 180°.
8x = 120°.
x = 120/8.
x = 15.

Step-by-step explanation:
Thirty adults were asked how many pets they have had over their lifetime. The results are shown in the histogram below.
A bar graph entitled Lifetime Pets has number of pets on the x-axis and number of adults on the y-axis. 14 adults had 1-5 pets; 9 had 6 to 10; 5 had 11 to 15; 2 had 16 to 20.
Which of the following is most likely true?
Answers
The true statement about the number of pets owned by the thirty adults is (b) The mean and median are both in the interval 6-10
What is an histogram?Histograms are graphs that are used to represent data, where the length of the bars represent the frequency
The data on the histogram are:
14 adults = 1-5 pets;
9 adults = 6 to 10 pets;
5 adults = 11 to 15 pets
2 adults = 16 to 20 pets
The mean is calculated as:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x = \frac{14 * 3 + 9 * 8 + 5 * 13 + 2 * 18}{30}[/tex]
This gives
[tex]\bar x = 7.2[/tex]
7.2 is in interval 6 to 10
The median is:
[tex]Median = \frac n2[/tex]
[tex]Median = \frac {30}2[/tex]
[tex]Median = 15th[/tex]
The 15th element is also interval 6 to 10
Hence, the true statement is (b) The mean and median are both in the interval 6-10

Consider the line y = 7x-5.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answers
Answer:
[tex]\boxed {\sf Parallel: 7 }[/tex]
[tex]\boxed {\sf Perpendicular: -\frac{1}{7}}}[/tex]
Step-by-step explanation:
First, identify the slope.
We are given the line y=7x-5.
This is in slope intercept form or y=mx+b where m is the slope and b is the y-intercept. So, the coefficient to x, or 7 in this case, is the slope.
m=5Now, find the parallel and perpendicular slopes.
1. Parallel Slope
Parallel lines never intersect, so they have the same slope. A parallel line has a slope of 7.
2. Perpendicular Slope
Perpendicular slopes intersect to form right angles. They have negative reciprocal slopes.
Negate the slope: 7⇒ -7 Find the Reciprocal (flip the numerator and denominator: -7/1 ⇒ -1/7A parallel line has a slope of 7 and a perpendicular line has a slope of -1/7.
Answer:
I'll help
Step-by-step explanation:
Parallel lines have the same slope so it will be 7.
And perpendicular lines if you multiply them together they have to add up to -1,
So 7 you change it to its opposite which is 1 over 7 and yeah just
