Answer:
Given equation is (8/y) = 2/(y-2) +1
=> (8/y)- 2/(y-2) = 1
=> [8(y-2)-2y]/(y-2)y = 1
=> (8y-16-2y)/(y²-2y) = 1
=> (6y-16)/(y²-2y) = 1
=> y²-2y = 6y-16
=> y²-2y -6y+16 = 0
=> y²-8y+16 = 0
The standard form is y²-8y+16 = 0.
Answer:
-6
Step-by-step explanation:
8/y = 2/y - 2 + 1
8/y = 2/y - 1
8 = 2 - y
6 = -y
y = -6
Use the distributive property to remove the parentheses.

Please help me with this!!!!!!!!!!!!!!!!!
Answer:
1. D.
2. B.
Step-by-step explanation:
1. D. None of the above.
If the three angles of one triangle are congruent to the three angles of another triangle, the triangles are similar, but there is not enough information to prove they are congruent.
2.
The given information gives us a side and an adjacent angle of each triangle.
Since all choices involve sides, we need another pair of sides to use SAS. The angle must be included by the two sides.
We need sides DF and JH to be congruent.
By knowing that DH is congruent to JF, you add HF to both segments giving DF congruent to JH, and the triangles are congruent by SAS.
Answer: B.

how many do 942 units cost?
the answer is not 13,188 because it says it's wrong for me.
Answer:
67.28
Step-by-step explanation:
uh I'm kinda unsure but I think you could try isolating the variable? so you could try 942 ÷ 14 = 67.28? just a guess, tell me if it works out!
Which graph shows a set of ordered pairs that represent a function?
Need help
Answer:
The third graph, the top right graph
Step-by-step explanation:
A function when determined graphically is a graph that passes the straight line test, which means if there is any two points on the graph which you can plot a vertical straight line going through both of them it is not a function. If 1 x value is equal to 2 y values, it is not a function.

The composition of function f ( x ) / g ( x ) = -x² + x - 1
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x⁴ - x³ + x²
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = -x²
Now , the composition of function is ( f/g ) ( x )
On simplifying , we get
( f/g ) ( x ) = f ( x ) / g ( x )
f ( x ) / g ( x ) = x⁴ - x³ + x² / -x²
f ( x ) / g ( x ) = -x² + x - 1
Hence , the function is A = -x² + x - 1

Answer:
y = -1x - 2/2
Step-by-step explanation:
Slope is -1
B = 2/-2
Answer:
y = x - 4
Step-by-Step Explanation:
Perpendicular lines have slopes that are negative reciprocals—multiplying their slopes result in -1.
Given the slope of a line m = -1, then it means that the slope of the other line must be 1 (because multiplying the slope of line 1 (m1 = -1), and the slope of the other line (m2 = 1) results in: -1 × 1 = -1).
Therefore, given the slope of line 2 (m2 = 1), and the point (2, -2), we could plug these values into the slope-intercept form and solve for the y-intercept (b):
y = mx + b
-2 = 1(2) + b
-2 = 2 + b
Subtract 2 from both sides to solve for b:
-2 - 2 = 2 - 2 + b
-4 = b
Therefore, the y-intercept (b) = -4.
Hence, the equation of the perpendicular line is: y = x - 4

Exercise #6: Demarco is trying to determine how many pennies he has without having to count
them. He first weighs 20 pennies and finds they have a total weight of 54 grams. He then weighs
all the pennies and finds they weigh a total of 918 grams.
(a) Determine how much a single penny
weighs, i.e. the grams per penny.
(b) Use your answer from (a) to determine
how many pennies Demarco has.
Step-by-step explanation:
20 pennies weigh 54 grams.
what is the weight of a single penny ?
well, 1/20 of the weight of the 20 pennies.
so,
54/20 = 27/10 = 2.7 grams
all his pennies weigh 918 grams.
how many pennies are there ?
as many as the times the weight of a single penny fit into the total weight.
so,
918 / 2.7 = 9180/27 = 340
he has 340 pennies.

Isha, a super excited candy crush user, has increased her points by 75% percents in a week. shes at 14000 points now. how many points did Isha have on candy crush last week?
If she has increased by 75% in a week to get 14000 points then we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.
175% * x = 14000
1.75x =14000 Divide both sides by 1.75
x= 8000
So she had 8000 points last week.
Check:
175% * 8000= 14000
1.75 * 8000 = 14000
14000 = 14000
Answer:
8,000 points
Step-by-step explanation:
x + 0.75x = 14,000 (the initial amount of points X plus 0.75x)
1.75x = 14000
x = 14000/1.75
x = 8,000

128 in exponential form
Answer:
2^12
Step-by-step explanation:
I know that 128 is 32 x 4, so 128 is 2^5 x 2 x 2 = 2^7. Thus,
128 x 32 = 2^5 x 2^7.
The last step is to realize that if two factors have the same base (in this case, both bases are 2), then you can add the exponents:
2^5 x 2^7 = 2^5+7= 2^12.
And that is in exponential form. So the final answer is
128 x 32 = 2^12
Answer:
[tex]128 \: \: is \: \: 32 \times 4, \\ \\ so 128 is {2}^{5} \times 2 \times 2 = {2}^{7} . \\ \\ Thus, 128 \times 32 = {2}^{5} \times {2}^{7} .[/tex]

Answer:
y = 2x + 5
Step-by-step explanation:
Finding the slope:
[tex]\frac{y2-y1}{x2-x1}\\[/tex]
= (1-(-3))/(-2-(-4))
= (1+3)/(-2+4)
= 4/2
= 2
Slope: 2
Substituting the slope into the formula 'y=mx+c':
y = 2x+c
Substituting any point (in this case, (-2,1)):
1 = 2(-2) + c
1 = -4 + c
c = 1 + 4
c = 5
Hence,
y = 2x + 5
