-7(w+4) +2w - 15 simplify
Answers
Answer:
w=-8.6 is your answer
-5w-43. is the simple version
Step-by-step explanation:
First distrubute the -7 and set equal to 0 so that we can move the w to the other side.
-7w-28+2w-15=0
-5w-43=0
add 43 to both sides so you can slove for w
-5w=43
divide both sides by -5 to isolate the w
w=-8.6

Answer:
No, she isn't
Step-by-step explanation:
(-2)² is basically -2 x -2, which we know is 4.
-2² is slightly different. In this case, you don't consider it as the square of -2, but you do the square ignoring the negative sign, and then add it at the end.
So think about it like this,
We do 2² first, and then add the minus, so it becomes -4 instead of positive 4. Does that make sense?
Answer: Incorrect
Step-by-step explanation:
Rule :
[tex](-10)^2=| -10|^2 =100 \\\\ -10^2=-(10)^2=-|10|^2=100[/tex]

Ronald wanted an allowance. his father gave him a choice of getting it on a weekly or on a daily basis. He said he would either pay him $1.25 a week or pay him in the following manner for a week: On Monday he would give him $0.01; On Tuesday $0.02; On Wednesday $0.04 and on through Sunday. What would you tell Ronald to do so he can get more allowance?
Answers
Step-by-step explanation:
Well the addition of ($0.01+$0.02+$0.04) would be $0.07
And he since he can get $1.25 a week if he chose the weekly option
Since $1.25>$0.07
I would tell Ronald to choose the weekly option for getting more allowance.

Answers
Answer:
1.5 pounds more.
Step-by-step explanation:
3.75 - 2.25
= 1.50.
Answer:
1.50 pounds
Step-by-step explanation:
Paula orders a macaroni salad and coleslaw each weighing 3.75 and 2.25 pounds respectively
so, to find how many more pounds of macaroni salad than coleslaw we do,
3.75-2.25=1.50
therefore, macaroni salad has 1.50 pounds more than coleslaw.

How would the domain and range of the function
Y = (1/4)x - 6
be determined? Explain.
Answers
Answer:
Domain and range both [tex](-\infty, \infty)[/tex]
Step-by-step explanation:
The range is determined by finding the domain of the inverse of the function(if it has one, in this case it does). The domain is easily determined, because [tex]x[/tex] can obviously range from [tex](-\infty, \infty)[/tex] without restriction.
The inverse of the function can be found as such:
[tex]x=(1/4)f^{-1}(x)-6\\x+6=(1/4)f^{-1}(x)\\4(x+6)=f^{-1}(x)\\f^{-1}(x)=4x+24[/tex].
Here, [tex]x[/tex] can also range from [tex](-\infty, \infty)[/tex] without restriction.
So, the domain and range are both [tex]\boxed{(-\infty, \infty)}[/tex]

What is the equation of the line that passes through the points (4, 15) and (0, 3)?
Answers
Answer:
Y=3x+3
Step-by-step explanation:
Gradient = :[tex]\frac{y2-y1}{x2-x1}[/tex] = :[tex]\frac{3-15}{0-4}[/tex] = :[tex]\frac{-12}{-4}[/tex] = 3
Y= mx + c
y = 3x + c
Insert x and y values for first point(4,15)
15 = 3 (4) + c
15 = 12 + c
3 = c
Y=3x +3
Answer:
The equation of the line is y=3x+3
Step-by-step explanation:
y=mx+b is the y intercept form of the equation of this line.
m=slope, and we find the slope by the equation m=y2-y1/x2-x1. Plugging our number into that formula, we get m=3 - 15/ 0 - 4, or -12/-4, which simplifies to 3.
Now we can add our slope into the formula.
y=3x+b
Next, we solve for the y intercept, or b. You can use whatever point to get the answer, but I will use 4 ,15).
y=mx+b is the equation, or substituting the numbers, gets you 15=3×4+b. now solve for b: b=15-(3)(4). b=3.
now, with slope and y intercept plugged in, the final equation is. y=3x+3

guys pls help me!!!!!!!
Answers
Your answer would be 154*. Reason being, if there are two parallel lines and a line running through them, you will only have 2 types of angles. The labeled 154* tells us that the angle to its right would be 26 degrees. Making line m = to 180 degrees at that angle. Then if you did the same thing with line t, you would get angle x to be equal to 154 degrees.
It is complicated like that, or as simple as just taking the 154 and saying that x has the same angle. Due to the fact that both angles are adjacent, they are the same.
