Answer:
x = 23
y = 157
Step-by-step explanation:
3x = x + 46 (outside angle of triangle theorem)
x + y = 180 (same side interior angles theorem)
<=>
2x = 46
x + y = 180
<=>
x = 23
y = 157

If u^2-c^2=36 and u-c=6, what is u+c
Answer:
u + c = 6
Step-by-step explanation:
u² - c² ← is a difference of squares and factors as
u² - c² = (u - c)(u + c) = 36 , thus
6(u + c) = 36 ( divide both sides by 6 )
u + c = 6

2) How much 64% acid solution should be mixed with 12 gallons of a 38% acid solution in order to make a 52% acid solution?
Answer: 14 gallons of the 64% acid solution is needed
============================================================
Work Shown:
x = amount, in gallons, of the 64% acid solution
0.64x = amount of pure acid from the stuff we're adding in
0.38*12 = 4.56 = amount of pure acid from 38% solution
In total, we have 0.64x+4.56 gallons of pure acid out of x+12 gallons total
Dividing the two amounts will give us the decimal form of the percentage. Set this equal to 0.52 and solve for x
-----------
(0.64x+4.56)/(x+12) = 0.52
0.64x+4.56 = 0.52(x+12)
0.64x+4.56 = 0.52x+6.24
0.64x-0.52x = 6.24-4.56
0.12x = 1.68
x = 1.68/0.12
x = 14 gallons is the amount of the 64% acid solution we need to add in

Because you have lots of questions, I answered it in a simplified way.
Please tell me if you have any question or need further explanation
A triangle has coordinates of A(1, 2), B(4, 6), and C(4, -3).
1. If the triangle is translated 2 units right, what are the new coordinates?
2. If ΔABC is reflected over the x-axis, what are the new coordinates?
Please show all work and not just the answer.
1 = (3,2) B= (6, 6) C = (6, -3)
Move two to the right since left and right deals with the x axis, add two to the x’s
2 = (1, -2) B = (4, -6) C = (4, 3)
Reflecting across the x axis means the formula is (x, -y) so switch the sign of the y’s
Answer:
1) A (3,2), B (6,6), C (6,-3)
2) A (1,-2), B (4,-6), C (4,3)
Step-by-step explanation:
1) Each of the x-values goes up two.
A (1,2) becomes (3,2)
B (4,6) becomes (6,6)
C (4,-3) becomes (6,-3)
2). I assume they mean the ORIGINAL ABC, not the one you just translated 2 units to the right.
To do this, you just multiply each y-value times negative one.
A (1,2) becomes (1,-2)
B (4,6) becomes (4,-6)
C (4,-3) becomes (4,3)

a patio in the shape of a rectangle, is fenced on all sides with 134 feet of fencing. the patio is 5 feet less wide than its long. what is the area of the patio?
Answer:
The area of the patio is 1,116 ft^2
Step-by-step explanation:
Here in this question, we are interested in calculating the area of the patio.
Mathematically, area of patio is;
length * width
Unfortunately we do not have these values. Thus we need to get this from the value of the perimeter of the fencing and the relationship between the width and the length.
Mathematically, the total length of the fencing is the perimeter of the fencing.
Now, we are also told that the patio is 5 feet less wide than it is long.
So if the length is x ft, the width is (x-5) ft
Mathematically;
the perimeter of a rectangle is;
2(l + b)
Writing this in the x terms and equating to the perimeter, we have;
2( x + x -5) = 134
divide through by 2
2x -5 = 67
2x = 67 + 5
2x = 72
x = 72/2
x = 36 ft
Thus since the length is 36 ft, the width would be x -5 = 36 -5 = 31 ft
Done? No!
The question asks to calculate the area. Let’s move these values to the initial equation of the area in the start of the question.
Thus, we have 31 * 36 = 1,116 ft^2

Answer:
Step-by-step explanation:
find the displacement
Answer:
55.
Step-by-step-explanation:
In a velocity/time graph like this the total displacement is the area of the body.
This is the area of (from left to right) of triangle OBF + area of the 2 rectangles + area of triangle CDE
Here this is 1/2 * 2 * 5 + 5 *4 + 5 * 4 + 1/2 * 5 * 4
= 5 + 20 + 20 + 10
= 55.
Answer:
55
Step-by-step explanation:
The displacement is the area under the line
The are comprises of
Triangle OBF + rectangle BEIF + triangle CDESo the area is:
1/2*2*5 + 5*8 + 1/2*4*5 = 55Give an odd function which of following transformations would result in an odd function
Answer: Reflection across the x-axis and Vertical stretch are the ones that return an odd function.
Step-by-step explanation:
An odd function f(x) is a function such that:
f(-x) = -f(x).
So let's analyze the options:
A) Horizontal translation.
An horizontal translation of A units to the right (A > 0) is written as:
g(x) = f(x - A)
Now, let's see if g(x) is also odd.
g(x) = f(x - A)
g(-x) = f(-x - A)
Now, f(-x - A) is equal to -f( x + A)
then:
g(-x) = f(-x - A) ≠ -g(x) = -f(x - A)
This is not an odd function.
B) Reflection over the x-axis.
When we have a point (x, y), a reflection over the x-axis changes the sign of the y-variable.
Then we have that:
g(x) = -f(x).
Then:
g(x) = -f(x)
g(-x) = -f(-x) = -(-f(x)) = f(x)
then:
g(x) = -f(x) = -g(-x)
This is an odd function.
C) Vertical stretch:
We can write a vertical stretch of factor scale A as:
g(x) = A*f(x).
Let's see if g(x) is odd:
g(-x) = A*f(-x) = A*(-f(x)) = -A*f(x) = -g(x)
this is a odd function.
C) Vertical translation:
A vertical translation of A units up (A > 0) is written as:
g(x) = f(x) + A.
Similar to the case of the horizontal translation, so it is easy to see that g(x) is not an odd function.
find x.

the distance a jet travels varies directly as the number of hours it flies. A jet traveled 2875 miles in 5 hours. What is the constant of variation
Answer:
k = 575
Step-by-step explanation:
let d be distance and h time.
Given d varies directly as h then the equation relating them is
d = kh ← k is the constant of variation
To find k use the condition d = 2875, h = 5, then
2875 = 5k ( divide both sides by 5 )
k = 575
