Answer:
slope : 3
y= 3x+2
Step-by-step explanation:
Answer:
Slope: 3 over 1 or 3
Y-intercept: 2
Equation: y = 3x +2
Step-by-step explanation:
Slope: You count up (or rise) from one point to another and you get 3. Then count right (or run) until you get to a point and you get 1. Slope is rise over run so 3 over 1 or simplified, 3.
Y-intercept: The point where the line crosses the y-axis. That is 2.
Equation: m=slope
b= y-intercept
So, y = 3x + 2
Which group of ordered pairs are on the line given by the equation 5x−2y=6?
Answer:
(0, -3), (2, 2), (4,7) these are just some points
Step-by-step explanation:
Put the equation in y=mx+b format. It will be 2y=5x-6.
y=5/2x -3
the first point will be (0, -3) because of the y-intercept which is negative 3. You can graph the slope from that point to get (2, 2) and (4, 7). You can get more points too
Answer:
There are infinite ordered pairs are on the line because it has infinite solutions.
Step-by-step explanation:
5x - 2y = 6
-5x -5x
-2y = -5x + 6
-2y/2 = -5x/-2 + 6/-2
y = 5/2x - 3
5x - 2(5/2x - 3) = 6
5x - 5x + 6 = 6
6 = 6

It takes Austin 8 hours longer than Elliott to construct a wooden chair in shop class. When the classmates work together, they can complete one chair in 3 hours. This situation can be represented by this expression, where t is the amount of time, in hours, it takes Elliott to complete a chair on his own.
The equivalent expression obtained using the least common multiple concept is [tex] \frac{6t + 24}{t^{2} +8}[/tex]
To solve, we need to obtain the L. C. M of the denominator values :
The L. C. M of t and t + 8 = [tex] t^{2} + 8t[/tex]
Hence,
[tex]\frac{3}{t} + \frac{3}{t+8} = \frac{6t + 24}{t^{2} +8}[/tex]
Therefore, the equivalent expression which represents the situation described above ls ;[tex] \frac{6t + 24}{t^{2} + 8t}[/tex]

Answer:
y = mx + b
Step-by-step explanation:
Substitute in the slope intercept formula
m = slope
x = first number in the point
y = second number in the point
and solve for b
Question 1
m=-1/2, x= -4 y=-2 substitute
-4 = -1/2(-4) + b
-4 = 2 + b
-4 -2 = 2 -2 + b
-6 = b
y=-1/2x -6

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
5x - 2w + t = 0
Solve for x.
5x - 2w + t = 0
5x = 2w - t
x = (2w - t)/5
Solve for w.
5x - 2w + t = 0
5x + t = 2w
w = (5x + t)/2
Solve for t.
5x - 2w + t = 0
t = 2w - 5x
Thus,
The value of x, w, and t is given above.

Answer:
PQ=30
Step-by-step explanation:
Knowing that the segment has 3 parts that are 3:1:1 and sum up to 50, you could find how much 1 would equal by finding the total in relation to the ratio (doing 3+1+1) which gets you 5 parts. Then you can divide the total (50) by 5 to figure out how much one part would equal (10). Now, since you know that 1 part is equal to 10 and that PQ is 3 parts, you can find that PQ is equal to 3x10, or 30.
Tina has two rectangular playpens to keep her new pet dogs. The first rectangle has a width of 6 feet and a length of x - 4 feet. The second rectangle has a width of 8 feet and a length of x + 2 feet. What is the sum of the two perimeters?
Answer:
4x+24 ft.
Step-by-step explanation:
Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.
Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.
Add these two together: 2x+4 + 2x+20 = 4x+24. Don't forget to add units: 4x+24 ft.
PLEASE HELP! THANKS!!!
Answer:
A. 3
B. 4.5
Explanation:
A. 2(5x - 3) = 24
10x - 6 = 24
then add six on both sides
U get 10x = 30
divide 10 on both sides
U get x is 3
B. 5(2x + 1) = 50
10x + 5 = 50
minus five on both sides
10x = 45
divide by 10 on both sides
The answer is x = 4.5
