Problem: Four students tried to write 12x + 3y=9 in equivalent y= mx + b form.
Question: Did each student get an equation that is equivalent to the original Ax + By=C form?
If so, explain the reasoning for each step. If not, tell what errors the students made.
What is the equation for the line perpendicular to the line y=−x+20 that passes through the point (−4, 2)?
Answer:
y = x + 6
Step-by-step explanation:
A line that is perpindicular to y = -x + 20 would be y = x. Now, we have to solve for the y-intercept. Knowing the line must cross through (-4,2) we can solve for the y-intercept using the equation y = x which is just up one over one. Going over 4 units to get to x = 0 means going up 4 units to get to y = 6. Now we know the y-intercept is 6. This means the final equation is y = x +6.

8+-2w>4
I dont know this i gotta solve fore w.
Answer:
w < 2
Step-by-step explanation:
Subtract 8 from both sides.
-2w > -4
Divide both sides by two. WHEN YOU DIVIDE BY A NEGATIVE, the sign FLIPS!
w < 2
There ya go! Please mark me as Brainliest; I need it to move on to the next level. =D
What is the slope of the line that passes through point (-8,3) and (-8,2)?
Answer:
[tex]\frac{-1}{0}[/tex] which is -1
Step-by-step explanation:
The slope formula is y2-y1 over x2-x1
So just plug it in. 2 - 3 = -1
-8 - -8 = 0
So the slope is -1 over 0

Answer:
622
Step-by-step explanation:
The n-th term of an arithmetic sequence is given by the formula ...
an = a1 +d(n -1)
where a1 is the first term (6), and d is the common difference (14-6=8).
Then the 78th term is ...
a78 = 6 + 8(78 -1) = 6 + 616 = 622
The 78th term is 622.

Solve the system of equations..
y = 8x - 6
y= 5x +9
Answer:
x = 5
y = 34
Step-by-step explanation:
Sub y = 8x - 6 into second equation (y = 5x + 9)
8x - 6 = 5x + 9
Rearrange by collecting like terms
8x - 5x = 9 + 6
3x = 15
x = 5
Sub x = 5 into first equation (y = 8x - 6)
y = (8*5) - 6
y = 40 - 6
y = 34

Helpppppp meeeeeeee help mee
Step-by-step explanation:
29x - 3 + 15x + 7 = 18 because these two angles are supplementary
29x + 15x + 7 - 3 = 18044x = 176 divide both sides by 44x = 413y - 17 = 29x - 3 because these two angles are alternate
since we know the value of x
13y - 17 = 29 × 4 - 313y - 17 = 11313y = 113 + 1713y = 130 divide both sides by 13y = 10A zero of the function ) is -5 + 3. Which of the following is the other zero of the function?

sam walks from home to his school which is 0.75 miles away in 12 minutes. how fast was he walking?
Answer:
3.75mph, or 0.0625 miles a minute
Step-by-step explanation:
12 times 5 is 60
.75 times 5 is 3.75
so he was walking mathematically 3.75 miles per hour
Answer:
3.75 mph
Step-by-step explanation:
12 minutes is 0.2 hours
0.75/0.2 = 3.75 mph

The weight of a honeybee is 1.2\cdot10^{-1}\text{ g}1.2⋅10 −1 g1, point, 2, dot, 10, start superscript, minus, 1, end superscript, start text, space, g, end text. The weight of the pollen collected by the bee on one trip is 6.0 \cdot 10^{-2} \text{ g}6.0⋅10 −2 g6, point, 0, dot, 10, start superscript, minus, 2, end superscript, start text, space, g, end text. What is the combined weight of the bee and the pollen? Express your answer in scientific notation.
Answer:
0.18 g
Step-by-step explanation:
Weight of honeybee = [tex]1.2\times 10^{-1}\ \text{g}[/tex]
Weight of pollen = [tex]6\times 10^{-2}\ \text{g}[/tex]
The above values can be written in the following ways
[tex]1.2\times 10^{-1}\ \text{g}=0.12\ \text{g}[/tex]
[tex]6\times 10^{-2}\ \text{g}=0.06\ \text{g}[/tex]
Weight mass = [tex]0.12+0.06=0.18\ \text{g}[/tex]
The combined weight of the honeybee and the pollen is 0.18 g.
Answer:
1.8 x 10^-1

How do you graph y=1/2x -2
Answer:
Graphing y=1/2x-2 will look like this on the graph
Answer:
Step-by-step explanation:
the 1/2 is a gradient so you go up 1 for every 2 to the right
the -2 is the Y intercept so you start graphing the gradient from -2 on the Y axis
