Answer:
1. Complementary Angles.
2. x=60°
Step-by-step explanation:
Part 1:
*Note: A complementary angle is when the sum of two angles equal 90 degrees. A Supplementary angle is when the sum of 2 angles equals 180 degrees.
In this instance, the 2 angles equal 90 degrees, as indicarted by the box on the angle. Therefore, the the angles are complentary.
Part 2:
1. Since we know that the sum of the two angles (x-30 and x) is 90 degrees, we can write an equation which says: (x-30) + x=90.
2. Then we'd simplify the equation by adding the like variables, and adding 30 to both sides:
2x=120
3. Now we will divide both sides by 2
[tex]\frac{2}{2} x=\frac{120}{2} \\x=60[/tex]
4. As a result, we get x=60, now label your answer with the degree sign, and enjoy your answer.
What is the measure for ECD
Answer:
118
Step-by-step explanation:
a triangle is 180 degrease and two sides that are equal to each other which means the angles across from them have the same thing.
so. 180-31-31=118

Solve the equation 17=5k-3
Answer:
k = 4
Step-by-step explanation:
17 = 5k - 3
+3. +3
20/5 = 5k/5
4 = k
k = 4
Answer: k = 4
17=5k-3
1. In order to solve this linear equation, we'll need to group all the variable terms on one side, and all the constant terms on the other side of the equation. In the problem, term -3 will be moved on the left side. Notice the sign changes when you move it to the left.
17=5k-3 ⇒ 17 + 3 = (5k - 3) + 320 = 5k - 3 + 3
2. Add the numerical terms.
20 = 5k - (3 + 3) = 6. Note: We don't need the six in the 3rd step.
20 = 5k
3. Switch the variable term. (Ex: 3x + 9 ⇒ 9 + 3x)
20 = 5k ⇒ 5k = 205k = 20
4. We will need to isolate the variable, to do that, get rid of the coefficient that it multiples. We can do that by dividing 5 by both sides.
5k/5 ÷ 20/5 = 1k/45k/5
5. We'll need to reduce 5k/5 to its lowest terms. We can divide the factors that appear both in the numerator and denominator. If we look at 5k/5, 5 appears both in the numerator and denominator.
5k/5 ⇒ k = 2²· 5/56. Lastly, we can do the same thing as we did in the 5th step. That'll lead us to k = 2²
7. Solve for 2²
2 x 2 = 4.
Hence, our answer is 4.

a certain shade of blue is made by mixing 1.5 quarts of blue paint with 5 quarts of white paint. If you need a total of 16.25 gallons of this shade of blue paint, how much of each color should you mix
Answer:
3.75 of blue mixed with 12.5 of white is the correct answer
Step-by-step explanation:
We know the blue and white paints are a 1.5 : 5 ratio, and if we have a total of 16.25 by 1.5 by 5.
1.5 * 2.5 = 3.75
------------------------
5 * 2.5 = 12.5
SO blue is 3.75 and white is 12.5
Answer:
blue is 3.75 and white is 12.5

A farmer is creating a rectangular garden such that the length is four times the width. The
area of the garden is 2077 square feet. Write and solve an equation to determine the width
of the garden, to the nearest tenth of a foot.
Answer:
Width of the garden = 22.8 foot
Step-by-step explanation:
Area of the rectangular garden = 2077 square feet.
Let
Width of the garden = x
Length of the garden = 4x
Area of a rectangular garden = length × width
2077 = 4x * x
2077 = 4x²
x² = 2077/4
x² = 519.25
find the square root of both sides
x = √519.25
x = 22.787057730211
To the nearest tenth of a foot.
x = 22.8 foot
Width of the garden = 22.8 foot

Answer:
Step-by-step explanation:
1. f(x) = 5x² + 3x - 1
a. f(0) = 5·0² + 3·0 - 1 = -1
b. f(-1) = 5(-1)² + 3(-1) - 1 = 1
Do the same for f(2), f(√2), f(a+2), and f(a).
Then do the same thing for the next function.
2. f(x) = x/(1-x)
a. f(0) = 0/(1-0) = 0
Do the same for f(-1), f(2), f(√2), f(a+2), and f(a).

Explain when you should reverse the inequality symbol when solving an equality.
Answer:
To do this, subtract 6 from both sides. − 3_x_ + 6 − 6 > 12 − 6. −3_x_ > 6. Now divide both sides of the inequality by −3. Since you're dividing by a negative number, you need to flip the inequality sign.

of the graph of the linear equation
y = 1/8x + 3
A) Slope: 8; y-intercept: 3
B) Slope: 1/3; y- intercept: 1/8
C) Slope: 1; y-intercept: 1/8
8
D) Slope: 1/8; y-intercept: 3
Answer:
D) Slope: 1/8; y-intercept: 3
Step-by-step explanation:
An equation in the form y = mx + b has certain characteristics that help us determine the slope and y-intercept of the line easily.
The variable "m" gives us the slope of the line, while the variable "b" gives us the y-intercept of the line.
Taking y = 1/8x + 3, we can see that the m-value is 1/8 and the b-value is 3.
Therefore, the slope of this line is 1/8 and the y-intercept is 3.
The answer is D) Slope: 1/8; y-intercept: 3.
f m<1 = 2x + 3 and the m<4 = 3x + 2, then find the m<3.
