(x-3) + (x+5) = 180°
2x + 2 = 180° --> Subtract 2 from both sides
2x = 178° --> Divide both sides by 2
x = 89°
☆Proof your answer☆
(89 - 3) + (89 + 5) = 180
86 + 94 = 180 ✅

Rewrite as an exponential equation.
Step-by-step explanation:
The first technique we will introduce for solving exponential equations involves two functions with like bases. Recall that the one-to-one property of exponential functions tells us that, for any real numbers b, S, and T, where
b
>
0
,
b
≠
1
,
b
S
=
b
T
if and only if S = T.
In other words, when an exponential equation has the same base on each side, the exponents must be equal. This also applies when the exponents are algebraic expressions. Therefore, we can solve many exponential equations by using the rules of exponents to rewrite each side as a power with the same base. Then we use the fact that exponential functions are one-to-one to set the exponents equal to one another and solve for the unknown.
For example, consider the equation
3
4
x
−
7
=
3
2
x
3
. To solve for x, we use the division property of exponents to rewrite the right side so that both sides have the common base 3. Then we apply the one-to-one property of exponents by setting the exponents equal to one another and solving for x:

how do you convert y=-2x²+4x-1 into vertex form
Answer:
y = –2(x – 1)² + 1
Step-by-step explanation:
Given the quadratic function, y = -2x²+ 4x - 1:
where a = -2, b = 4, and c = -1
The vertex of a parabola is the point on the graph where the parabola intersects the axis of symmetry. The axis of symmetry occurs at x = h. Therefore, the x-coordinate of the vertex is the same as h.
To find the vertex, (h, k), you need to solve for h by using the formula:
Plug in the values into the formula:
[tex]h = \frac{-b}{2a}[/tex]
[tex]h = \frac{-4}{2(-2)} = 1[/tex]
Therefore, h = 1.
Next, to find the k, plug in the value of h into the original equation:
k = -2x²+ 4x - 1
k = -2(1)²+ 4(1) - 1
k = 1
Therefore, the value of k = 1.
The vertex (h, k ) occurs at point (1, 1).
Now that you have the value for the vertex, you can plug these values into the vertex form:
y = a(x - h)² + k
a = determines whether the graph opens up or down; it also makes the parent function wider or narrower.
If a is positive, the graph opens up. If a is negative, the graph opens down.h = determines how far left or right the parent function is translated.
k = determines how far up or down the parent function is translated.
Plug in the vertex, (1, 1) into the vertex form:
y = –2(x – 1)² + 1
This parabola is downward facing, with its vertex, (1, 1) as its maximum point on the graph.

Pls MARK BE BRAINLIEST :)
The missing value in the ratio that we have in the question is obtained as 54.
What is a ratio?To find the missing value, we can set up a proportion using the given equivalent ratios.
The equivalent ratios are 6:5 and ___:45.
We can write the proportion as:
6 / 5 = ___ / 45
Let the missing number be x in the expression that has been written in the question or problem that we have here thus we have that;
6/5 = x/45
x = 6 * 45/5
x = 54
Thus we would have the missing value that is here as 54.

Answer:
Cathleen walked 3/8 mile.
Step-by-step explanation:
Since we are trying to find 1/2 of 3/4, we'll start by converting 3/4 into a form where we can find 1/2, becuase 1.5/4 is not a valid answer.
The simplest form other than 3/4 would be 6/8, we'll get that by multiplying 3 by 2 and 4 by 2. We just need to find half of 6, which is 3. Therefore, Cathleen walked 3/8 mile.
