Answer:
y=1
Step-by-step explanation:
Let's solve your equation step by step.
Step 1: Simplify both sides of the equation.
−4(2y−4)−4y=4
(−4)(2y)+(−4)(−4)+−4y=4(Distribute)
−8y+16+−4y=4
(−8y+−4y)+(16)=4(Combine Like Terms)
−12y+16=4
−12y+16=4
Step 2: Subtract 16 from both sides.
−12y+16−16=4−16
−12y=−12
Step 3: Divide both sides by -12.
y=1

Which equation in point-slope form describes the line that passes through the point (4,-5) and is perpendicular to
the line represented by
- 7x + 2y = 14?
9514 1404 393
Answer:
D y +5 = -2/7(x -4)
Step-by-step explanation:
The point-slope form is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
You're given (h, k) = (4, -5), so the equation will be of the form ...
y +5 = m(x -4) . . . . for some slope m
This form eliminates the first two choices.
__
The slope of the given line is the coefficient of x when solved for y:
2y = 7x +14
y = 7/2x +7 . . . . slope is 7/2
The perpendicular line will have a slope that is the opposite reciprocal of this, ...
-2/7 . . . . slope of perpendicular line
This is the slope shown in choice D:
y +5 = -2/7(x -4)
D

Answer: x=60
Step-by-step explanation:
Hey! X would be 60 because the diagram on the left has proportions of 6/6. The diagram on the right has a porportion of x/60. We want the proportions to be equal so it has to be 60!
6/6 = 1
60/60 = 1 (they are now equal and have equal proportions!)
You want to purchase multiple books on sale for $6.30. The sales tax is 5% and you have $20. At most, how many books can you buy?
Answer:
3 books
Step-by-step explanation:
Assume x is the number of books you could buy.
(1+0.05)(6.3x) ≤ 20
1.05(6.3x) ≤ 20
6.615x ≤ 20
x ≤ 3.02

i need help with geometry!
Step-by-step explanation:
If m is parallel to n and one of its angle is 25
Therefore, the vertically opposite angle to angle of 25 is also equal to 25
Now, we have to find x
Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)
Therefore, x =155

i need to find the 9th term of this sequence
9514 1404 393
Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244
