Answer:
F. t = 6
Step-by-step explanation
5t - 3 = 3t + 9
add 3t to both sides
2t - 3 = 9
add 3 to both sides
2t = 12
divide both sides by 2
t = 6

Assume y varies inversely as x. If y = 60 when x = 80, find x when y = -20
Answer:
I think the answer is -40
Step-by-step explanation:
what I did was added the -20 +-20Answer:
x=0
Step-by-step explanation:
so we are going to first subtract by both sides,
x=80 y=60
-20 -20
------------------------
x=60 y=40
then again,
x= 60 y=40
- 20 -20
---------------------
x=40 y=20
and again,
x=40 y=20
-20 -20
-----------------
x=20 y=0
then lastly again,
x=20 y=0
-20 -20
------------------
x=0 y=-20

Find the value of x and YZ if Y is between X and Z.
XY = 4x, YZ = x, and XZ
25
Answer:
The value of x is 5
The length of YZ is 5 units
Step-by-step explanation:
If a point lies on a line segment, then it divides it into 2 parts, the sum of their length equals the length of the line segment
Let us use this fact to solve the question
∵ Point Y is between points X and Z
→ By using the fact above
∴ XY + YZ = XZ
∵ XY = 4x and XZ = x
∵ XZ = 25
→ Substitute then in the equation above
∴ 4x + x = 25
→ Add the like terms in the left side
∴ 5x = 25
→ Divide both sides by 5 to find x
∵ [tex]\frac{5x}{5}[/tex] = [tex]\frac{25}{5}[/tex]
∴ x = 5
∴ The value of x is 5
∵ YZ = x
∵ x = 5
∴ YZ = 5
∴ The length of YZ is 5 units

Find a point on the line and the line's slope. y - 1 = -4/3 (x -4)
point on line:
slope:
Answer:
[tex]\displaystyle\text{Slope: } -\frac{4}{3}[/tex]
Point (4,1)
Step-by-step explanation:
The Equation of the Line
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
The given line is:
[tex]\displaystyle y-1=-\frac{4}{3}(x-4)[/tex]
If we compare the equation of this line, both the slope and the point through which is passes are clearly identifiable:
Slope:
[tex]\mathbf{\displaystyle -\frac{4}{3}}[/tex]
Point (4,1)

Math standard form. help!
Answer:
y=mx+b is slope-intercept form
Ax+By=C is standard form.
IN y=mx+b, m represents the slope and B represents the y intercept.
To switch from standard form to slope-intercept form all we need to do is get y alone. thats it. By folowing these steps:
-6x+5y=-30
-6x+6x+5y=-30+6x - this cancels the x on the left side of the equation bringing us one step closer to getting y alone
5y=-30+6x
5y / 5=(-30+6x) / 5 -this last step leaves y alone and brings us to slope intercept form.
y=-6+30x
y=30x-6 - i switched the 30x and 6 because y=mx+b not y=b+mx
y=30x-6
SInce m represents the slope and b represents the y itnercept, 30 is the slope and -6 is the y intercept
30=m(slope)
-6=b(y-intercept)
Btw because the slope is 30 it means the line with point like so: / since it has a positive slope.
Hope this helps!

Which division problem is shown by the model?
Answer:
Ithink this would be 12/3
Step-by-step explanation:
12 blocks in total grouped into 3 groups.
The division problem shown here is 12 columns divided into a group of 3.
what is a picture model?Using models, or pictures, can help to visualize and solve math problems. Models can include number blocks, in which a small square equals 1, a long rectangle equals 10, and a large square equals 100.
Given here are 12 columns arranged in 3 square boxes
thus the picture problem must be arranging 12 columns using 3 groups
therefore, 12÷3 = 4 columns
Hence, the division problem is arranging 12 groups in 3 groups of 4 columns in each group.
