Step-by-step explanation:
Cuz the opposite of addition is subtraction so they should ve subtracted -2x from both sides and not add.
TIME REMAIN 56:07 What method can be used to write the equation of a line in slope-intercept form given two points? Find the slono uning
Step-by-step explanation:
1. Pick two points on the line and use them to find the slope.
2. Then, find the coordinates of the y-intercept.
3. The y- coordinate is the value of b in the equation.
Answer:
Step-by-step explanation:
First find the slope of the line.
If the 2 points are (x1, y1) and (x2, y2) then the slope is (y2-y1)/(x2-x1).
Then we can use the point-slope form of the equation of the line:
y - y1 = m(x - x1) where m = the slope and by substituting the point (x1, y1) we can convert the equation to slope intercept form ( which is y = mx + b).
Example:
Find slope-intercept equation for the line joining the points (1, 0) and (3, 4):
The slope = (4 - 0)/(3 - 1) = 4/2 = 2.
Now we plug in the slope m and the point (3, 4) into y - y1 = m(x - x1):
y - 4 = 2(x - 3) (Note we can use (1, 0) OR (3, 4) as they are both on line).
y - 4 = 2x - 6
y = 2x - 6 + 4
y = 2x - 2 which is slope-intercept form.

Angle A and angle B are complementary angles. Angle A is 30 degrees. What is the measure
of angle B?
Answer:
60°
Step-by-step explanation:
A=30°
B=?
lets B be x
A=30°
x+30°=90°
x+30°-30°=90°-30°
X=60°

For a walk-a-thon a sponsor committed to give you a flat free of $5 plus $2 for every mile m you walk
Answer:
$45
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION BELOW;
For a walk-a-thon a sponsor committed to give you a flat fee of $5 plus $2 for every mile you walk. If you walk for 20 miles, what is the total amount you will collect from your sponsor at the end of the walk-a-thon?
$5 was given for participants of the walk-a-thon.
$2 was given for every miles won
Then, for "y" number of miles, the the amount that can be won is ( 2×y)= 2y
The Total amount that can be given
= (5 + 2y)
Where "y" is the miles value
Then, if you walk for 20 miles, The Total amount that can be given
= 5 + 2(20)
= 5+ 40
= $45

PLEASE HELP ITS DUE SOIN AND I DONT KNOW HOW TO ANSWER
Answer:
y = - 3
Step-by-step explanation:
Given the 2 equations
6x + 11y = - 3 → (1)
4x + y = = 17 → (2)
Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x
24x + 44y = - 12 → (3)
- 24x - 6y = - 102 → (4)
add (3) and (4) term by term to eliminate x
0 + 38y = - 114
38y = - 114 ( divide both sides by 38 )
y = - 3
Red and grey bricks were used to build a decorative wall. The number of red bricks and grey bricks was 5/2. There were 140 bricks used in all. How many red bricks were used?
Group of answer choices
40
100
20
28
Answer:
100 red bricks
Step-by-step explanation:
Let's say red bricks is equal to 5x
Gray bricks is equal to 2x
We have an equation
2x + 5x = 140
= 7x = 140
Divide through by 7 to get the value of x
X = 140/7
X = 20
Red bricks = 5(x)
= 5(20)
= 100
Gray bricks = 2(x)
= 2(20)
= 40
Therefore in conclusion the number of red bricks is 100.

Alyssa estimates that her school's gym can hold 660 students. It actually has 750 seats. What is the percent error of her estimate?
Answer: 13.64%
Step-by-step explanation:
Alyssa estimates that the gym can hold 660 students even though it can hold 750.
Her percent error is calculated by:
= (Actual seats - Estimated seats) / Estimated seats
= (750 - 660) / 660
= 90 / 660
= 0.1364
= 13.64%
