What is the correct answer for both?
Answer:
19) D (-8, -2)
20) B (0, 8)
Step-by-step explanation:
-x - y = 10
-6x + 11y = 26
-x - y = 10
-x = 10 + y
x = -10 - y
-6x + 11y = 26
-6(-10 - y) + 11y = 26
60 + 6y + 11y = 26
60 + 17y = 26
17y = -34
y = -2
-x - y = 10
-x - (-2) = 10
-x + 2 = 10
-x = 8
x = -8
_______________
-x + y = 8
3x + 2y = 16
-x + y = 8
y = 8 + x
3x + 2y = 16
3x + 2(8 + x) = 16
3x + 16 + 2x = 16
5x + 16 = 16
5x = 0
x = 0
-x + y = 8
-0 + y = 8
y = 8
what is the measure of the line segment AB if D is between A and B, AD = 7, and DB = 12?
Answer:
Given AD = 7 and DB = 12, to find AB you need to add them
AB = 12+7
AB = 19
The measure of the line segment AB is 19 units.
What are the coordinates of midpoint of the line segment AB?Suppose we've two endpoints of a line segment as:
A(p,q), and B(m,n)
Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:
[tex]x = \dfrac{p+m}{2}andy = \dfrac{q+n}{2}[/tex]
We are given that;
AD = 7, and DB = 12
Now,
To find the measure of the line segment AB, we need to use the segment addition postulate. The segment addition postulate states that if a point is between two other points on a line segment, then the sum of the lengths of the two smaller segments is equal to the length of the larger segment.
In this problem, D is between A and B, so we can apply the segment addition postulate and write:
AD + DB = AB
Substituting the given values of AD and DB, we get:
7 + 12 = AB
Simplifying, we get:
19 = AB
Therefore, by the given point the answer will be 19 units.

What is the slope of the line parallel to 7x + 4y = -16?
Answer:
The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]
Step-by-step explanation:
Parallel lines have the same slopes and different y-intercepts
The slope of the line who has an equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]
Let us use these rules to solve the question
∵ The equation of a given line is 7x + 4y = -16
→ Compare it with the form of the equation above
∴ a = 7 and b = 4
∵ The slope of the line = [tex]\frac{-a}{b}[/tex]
∴ The slope of the line = [tex]\frac{-7}{4}[/tex]
∵ Parallel lines have the same slope
∴ The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]
Brianna jogs 15 minutes more on Sunday than Saturday. She jogged 26 minutes on Saturday.
a.
How many minutes does she jog on Sunday?
Answer:
41
Step-by-step explanation:
15+26=41
Answer:
41 minutes
Step-by-step explanation:
If she jogged 15 minutes more on Sunday than Saturday, we can find how many minutes she jogged on Sunday by adding 15 to Saturday's amount:
So, add 15 to 26:
15 + 26
= 41
So, she jogged 41 minutes on Sunday.

What is the answer to this question?
Answer:
≈ 3.9 miles
Step-by-step explanation:
The third angle in the triangle is
180° - (53 + 78)° = 180° - 131° = 49°
Using the Sine rule in the triangle with distance from 2 being x, then
[tex]\frac{3}{sin49}[/tex] = [tex]\frac{x}{sin78}[/tex] ( cross- multiply )
x × sin49° = 3 × sin78° ( divide both sides by sin49° )
x = [tex]\frac{3sin78}{sin49}[/tex] ≈ 3.9 ( to the nearest tenth )

In 2018, Gretal earned $32 000.
(i) She paid tax of 24% on these earnings.
Work out the amount she paid in tax in 2018
Gretal paid $7680 on tax in 2018.
What is a percentage?"A percentage is a ratio of a number to 100. The symbol % is used to indicate a percentage."
Given
Earning = 32000
Tax paid = 24%
Amount paid on tax = [tex]32000[/tex] × [tex]\frac{24}{100}[/tex]
= $7680
Hence, she paid $7680 on tax.

y = - x + 7 ← is in slope- intercept form
with slope m = - 1
Mario deposited $6,500 in a simple interest account that pays 2.8% interest annually. If Mario leaves the money in the account for 12 years, how much interest will he earn?
Answer:
$2,184
Step-by-step explanation:
Simple interest = (Principal × Rate × Time) / 100
Principal = $6,500
Rate = 2.8%
Time = 12 years
Simple interest = (Principal × Rate × Time) / 100
= (6,500 × 2.8 × 12) / 100
= 218,400 / 100
= 2,184
Simple interest = $2,184
The simple interest on $6,500 at 2.8% for 12 years is $2,184
what is the y - intercept
Answer:
The y- intercept is 1
Step-by-step explanation:
Since the line crosses the y-axis at 1, the y-intercept is 1. Like the x-intercept. The line crosses the x-axis at um.. I would say about -1.5, so the x-intercept is -1.5.
