Answers
Answer:
(7,6)E=-5|100510>
Step-by-step explanation:
128211~}>■•
Step-by-step explanation:
1. The vertex is the x coordinate of the lowest point of the parabola. The lowest possible point is (1,-2). So our vertex is 1.
2. The axis of symmetry passes through the vertex so the axis of symmetry is at the line x=1 .
3. X intercepts are what are the x values when y =0. The x intercepts are -2 and 4.
4.Reflect the point 7,6 across the line x=1. A point symmetric to it is (-5,6)

Solving the formula P = 2L + 2W for W is NOT equivalent to which equation?
Answers
Answer:
3rd one
Step-by-step explanation:
2l + 2w = P
2w = P - 2l
w = P - 2l / 2
Therefore, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]2L + 2w = P\\\\2(L+w)=P\\\\L+w=\frac{1}{2}P\\\\w=\frac{1}{2}P-L\\\\w=\frac{P-2L}{2}\\\\w=P-\frac{1}{2}L[/tex]
Hence, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].

Answer:
BCF = 140°
See attached image.
Answer:
m<BCF=140°
Step-by-step explanation:
first find m<BCD
m<BCD=180-50-90
m<BCD=40°.
to find m<BCF, we can do 180-m<BCD, since m<BCD and m<BCF add up to 180° (they form a straight angle)
180-m<BCD=m<BCF
180-40=m<BCF
m<BCF=140°

Answers
Simplifying
4(x + 2) = 28
Reorder the terms:
4(2 + x) = 28
(2 * 4 + x * 4) = 28
(8 + 4x) = 28
Solving
8 + 4x = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 4x = 28 + -8
Combine like terms: 8 + -8 = 0
0 + 4x = 28 + -8
4x = 28 + -8
Combine like terms: 28 + -8 = 20
4x = 20
Divide each side by '4'.
x = 5

x = 5
2. 2 (x+4)=28

Answer:
The answer is p = 2.
Step-by-step explanation:
1) Divide both sides by 9.
[tex]p - 4 = - \frac{18}{9} [/tex]
2) Simplify 18/9 to 2.
[tex]p - 4 = - 2[/tex]
3) Add 4 to both sides.
[tex]p = - 2 + 4[/tex]
4) Simplify -2 + 4 to 2.
[tex]p = 2[/tex]
Therefor, the answer is p = 2.
Answer:
p =2
Step-by-step explanation:

Answer:
Step-by-step explain to solve for the maximum area, the first derivative should be solved and equate it to zero, then solve for x.
A = 37x - x^2
dA / dx = 37 - 2x
equate dA / dx = 0
0 = 37 - 2x
2x = 37
x = 37 / 2
x = 18.5 ft
so the maximum area is
A = 37x - x^2
A = 37( 18.5) - 18.5^2
A = 342.25 sq ft
so the answer is letter B

Answer:
x = 5
Step-by-step explanation:
Perhaps you want to solve for x the rational equation ...
(2+5x)/(3x) = (7x -18 +2x)/(3x)
Multiplying by 3x and collecting terms, we have ...
2 +5x = 9x -18
20 = 4x . . . . . . add 18-5x to both sides
5 = x . . . . . . . . divide both sides by 4
The solution is x=5.

Arc UR central angle is 10x.Arc RS central angle is x+61Arc ST central angle is x+63Arc TU central angle is x+80.Since an arc's central angle measure equal the arc measure,
