How do I solve for x 7x–1=125
Answer:
x=18
Step-by-step explanation:
You add 1 on each side so you have 7x=126. Then you divide each side by 7, so you get x=18! Hope this helps!
(2 4/5) x (-5 2/3) whats the answer I need help
Answer: 4/5
Step-by-step explanation:
5(y + 2) = 4(x - 3)
Divide each side by 5
5/5(y + 2) = 4/5(x - 3)
(y + 2) = 4/5(x - 3)
This is in point slope form
(y - y1) = m(x - x1)
4/5
What is the equation of the line in slope-intercept form?
Answer:

Which of the following relations has a range of {-8, -6, 4}?
A. {(-8,2), (-6,2), (4,2)}
B. {(-8,2), (-6,4), (2,4)}
C. {(1, -8), (4, -6), (1, -6) (4, -4)}
D. {(1, -8), (4, -6), (1, -6) (5,4)}
Answer:
D. {(1, -8), (4, -6), (1, -6) (5,4)}
Step-by-step explanation:
The Range of a Relation
Is the set of all second elements of ordered pairs (y-coordinates). Only the elements used by the relation or function constitute the range.
For example, for the ordered pair of a relation (5,2), 5 belongs to the domain and 2 belongs to the range.
Given the range {-8,-6,4} we only have to go through the options and check which one has these values as the second element of the ordered pairs.
Note option D has y-coordinates -8, -6, -6, and 4. Those values correspond to the given range, thus the answer is
D. {(1, -8), (4, -6), (1, -6) (5,4)}

Question 17
Answer: choice C) y = (x-2)^2 - 3--------------------
Explanation:
We know that a = 1 so it matches with the 'a' value in y = x^2. Otherwise, the shapes wouldn't match up and they wouldn't be congruent.
The vertex we want is (h,k) = (2,-3)
Therefore,
y = a(x-h)^2 + k
y = 1(x-2)^2 + (-3)
y = (x-2)^2 - 3
================================================
Question 18
Answer: choice B) min point; -4--------------------
Explanation:
The equation y = 3(x-1)^2 - 4 is in the form y = a(x-h)^2 + k which is known as vertex form.
a = 3 being positive tells us the graph opens upward and we have a min point. There is no max point as it goes on forever upward.
The min point is k = -4 which is the y coordinate of the vertex.
================================================
Question 19
Answer: Choice B) y = (1/2)x^2 + 3x - 5--------------------
Explanation:
The equation opens up, so the value of 'a' must be positive. This narrows our choices to A or B.
We eliminate choice A because that graph is more narrow compared to y = x^2. Choice B is wider and flatter compared to y = x^2 due to 1/2 being smaller than 1.
Is 900% of 6 less than 10, greater than 10 but less than 100, or greater than 100?

A goat is tied to the corner of a rectangular shed in a large field full of grass. The rope is 2 yards long and a plane view (from above) of the shed and field is shown below. Use this information for Parts A and B below.
Part A: Calculate the area of grass that the goat can eat.
Part B: What length of rope would enable the goat to eat 30 square yards of grass? Show all your reasoning.
Answer:
9.42 yd²3.57 ydStep-by-step explanation:
Part AThe area of circle with radius of 2 yd (the length of the rope) is:
A = π*r² = 3.14*2² = 12.56 yd²Since 1/4 of the circle is occupied by the shed, the area of the grass is:
12.56*3/4 = 9.42 yd²Part BLet the area be 30 yd², finding the r as per above formula:
3/4*3.14*r² = 30r² = 30*4/3*3.14r² = 12.74r = √12.74r = 3.57 ydbrainly math tester 2020
What do u need? Tell me :)
please help me I really need it
Answer:
15 grams .
Step-by-step explanation:
We need to multiply the percentage as a decimal (0.30) with the amount of chocolate (50 g):
0.30*50 = 15 g
There are 15 grams of cocoa in the chocolate bar.
Work Shown:
30% = 30/100 = 0.30
30% of 50 = 0.30*50 = 15
Here's another way to think about it: If we had 100 grams of chocolate and 30% are cocoa, then we have 30 grams of cocoa by definition of what percentage means. Divide the 100 in half to get 50, so we'll have to divide the 30 in half to get 15.

solve for x and why please using these!!!
Answer:
[tex]x = 40[/tex]
[tex]y = 5[/tex]
Step-by-step explanation:
[tex]4x = 2x+80\\2x = 80\\x = 40[/tex]
Edit: Solve for Y
A straight line is 180 degrees so one side (the x side) is 160°, The Y side is 20, and you can work backwards by -
[tex]8y - 20 = 20\\8y = 40\\y = 5[/tex]
Which of the following represents the prime factortzation of 72?
023.32.4
th
023.32
02.32.42
22.33
Answer:
2³ x 3²
Step-by-step explanation:
The prime factorization of a number is the process of breaking down a number to a set of prime numbers that their product will give the original number:
72
2 x 36
2 x 2 x 18
2 x 2 x 2 x 9
2 x 2 x 2 x 3 x 3
So;
The prime factorization is 2³ x 3²

Solve for x.
4x +4=12
Answer:
x = 2
Step-by-step explanation:
4x +4=12
-4. -4
4x.= 8
divide both saide by 4
x. = 2
Subtract 4 from both sides
4x + 4 - 4 = 12 -4
Simplify
4x = 8
Divide both sdes by 4
4x/4 = 8/4
Simplify
x = 2
