Delta Math:Angle Terminology with Equations
Answer:
∠A = 94°
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180°.
Therefore, if ∠A and ∠B are supplementary:
⇒ ∠A + ∠B = 180
⇒ (2x + 10) + (2x + 2) = 180
⇒ 4x + 12 = 180
⇒ 4x = 168
⇒ x = 42
To find ∠A, substitute found value of x into the expression for ∠A:
⇒ ∠A = 2(42) + 10 = 94°

Consider the following system of equations:
y = -x + 2
y = 3x + 1
Which description best describes the solution to the system of equations?
Line y = -x + 2 intersects line y = 3x + 1
Lines y = -x + 2 and y = 3x + 1 intersect the x-axis.
Lines y = -x + 2 and y = 3x + 1 intersect the Y-axis
Line y = -x + 2 intersects the origin
Answer:
Line y = -x + 2 intersects line y = 3x + 1
Step-by-step explanation:
The solution to a system of equations is the point at which the two lines intersect. To find this point, first equate the equations and solve for x:
[tex]\begin{aligned}y & = y\\-x + 2 & = 3x + 1\\-x+2+x & = 3x+1+x\\2 & = 4x + 1\\2-1 & =4x+1-1\\1 &=4x\\x & =\dfrac14\end{aligned}[/tex]
Substitute the found value of x into one of the equations, and solve for y:
[tex]y=3\left(\dfrac14\right)+1=\dfrac74[/tex]
Therefore, the solution to the system of equations (the point at which the two lines intersect) is:
[tex]\left(\dfrac14,\dfrac74\right)[/tex]
So the description that best describes the solution to the system of equations is:
Line y = -x + 2 intersects line y = 3x + 1

Which equation represents a linear function rule for the following set of ordered pairs?
x y
1 -1
2 -4
3 -7
A. y = -3x + 2
B. y = -3x - 2
C. y = -2x + 3
D. y = -2x - 3
The equation that represents the linear function for the set of ordered pairs is: A. y = -3x + 2.
What is the Equation of a Linear Function?Equation of a linear function, where m is the slope and b is the y-intercept, is expressed as y = mx + b.
Find the slope (m):
Slope (m) = change in y/change in x = (-7 -(-4)) / (3 - 2)
Slope (m) = -3/1 = -3
Find b by substituting m = -3 and (1, -1) = (x, y) into y = mx + b:
-1 = -3(1) + b
-1 = -3 + b
-1 + 3 = b
2 = b
b = 2
Substitute m = -3 and b = 2 into y = mx + b
y = -3(x) + 2
y = -3x + 2
Therefore, the equation that represents the linear function for the set of ordered pairs is: A. y = -3x + 2.

Homer and Marge are in the 28% tax bracket. Their joint taxable income is $139,450. If the first $16,050 is taxed at 10%, with the remainder at 28%, how much tax will they owe?
$36,157
$139,450-$16,050=123,400
123,400×28% (or .28)=34,552
16,050×10% (or .10)=1,605
34,552+1,605=$36,157

Side opposite to 30° is the shortest leg and it is a
Side opposite to 60° is the longest leg and it is a√3
side opposite to 90° is hypotenuse and it is 2a and it the longest side.
7) a = 8 (Which is opposite to 30°)
w = 2a = 2*8
w = 16
v = √3a = √3 *8
v = 8√3
8) a√3 = 5√3 (Which opposite to 60°)

exactly 5 liters of punch and include at least three of the juices. Also be sure
to include how many containers of each juice you need. Show your work by
writing equations that show how you determined the capacity.
Your fruit punch recipe can be composed of 4 juice containers of lemonade, 2 juice containers of orange juice, 2 juice containers of grape juice, 2 juice containers of apple juice, 2 juice containers of cranberry juice, and 2 juice containers of pineapple juice.
Unit conversionUnit conversion is a tool very useful to solve some questions. For this exercise, you should know that 1 liter (l) = 1000 milliliters (ml).
The question asks you a design your own fruit punch recipe with exactly 5 liters of punch and includes at least three of the juice.
You have several options, an alternative is to use all juices.
Step 1 - Convert the units for each given juice containers250 milliliters of lemonade = 0.250 l of lemonade juice
500 milliliters of orange juice = 0.500 l of orange juice
250 milliliters of grape juice = 0.250 l of grape juice
250 milliliters of apple juice= 0.250 l of apple juice
500 milliliters of cranberry juice = 0.500 l of cranberry juice
500 milliliter’s of pineapple juice = 0.500 l of pineapple juice
Step 2 -Design your own fruit punch recipe with exactly 5 liters4 juice containers of lemonade = 4* 0.250 l = 1 l of lemonade
2 juice containers of orange juice= 2* 0.500 l = 1 l of orange juice
2 juice containers of grape juice= 2* 0.250 l = 0.500 l of grape juice
2 juice containers of apple juice= 2* 0.250 l = 0.500 l of apple juice
2 juice containers of cranberry juice= 2* 0.500 l = 1 l of cranberry juice
2 juice containers of pineapple juice= 2* 0.500 l = 1 l pineapple juice
Thus, your own fruit punch recipe is composed of: 4 juice containers of lemonade, 2 juice containers of orange juice, 2 juice containers of grape juice, 2 juice containers of apple juice, 2 juice containers of cranberry juice, and 2 juice containers of pineapple juice.

Six increased by product of x and four is 22. What is x?
Answer: 4
Step-by-step explanation:
Terms: Increased means adding, a product means multiplication.
1. Convert it into an equation: 6+4x=22
2. Then subtract 6 from the left side and pass it to the right to get 22-6= 16. Now, you have 4x=16.
3. Then you want to leave the x alone, so you divide both sides of the equation by 4.
4. Therefore, your answer is 4!

In HPE and GKJ, Which of the following would be enough to prove FPH ~ JKG?
[tex]\frac{KJ}{JG} = \frac{PF}{FH}[/tex]
======================================================
Explanation:
Refer to the drawing below. I started off with the original diagram given, then I split up the triangles HPF (red) and GKJ (blue)
We're given that [tex]\angle GJK \cong \angle HFP[/tex]. If we had another congruent pair of angles, then we could use the AA (angle angle) similarity theorem to prove the triangles are similar. However, none of the answer choices mention another pair of congruent angles. Choices A and B are very close, but the [tex]\sim[/tex] should be [tex]\cong[/tex] instead. So we rule them out.
Focus on triangle GJK. Notice how the sides KJ and JG are surrounding the angle GJK. In other words, angle GJK is sandwiched between sides KJ and JG. Similarly, angle HFP is sandwiched between sides PF and FH in triangle HFP.
If we knew that the ratios KJ/JG and PF/FH were the same, then that would be enough info to use the SAS (side angle side) similarity theorem to prove the triangles similar. So that's why we go for [tex]\frac{KJ}{JG} = \frac{PF}{FH}[/tex]
There are other possible ways to write that equation.

Answer:
Make a table of values. Take numbers starting from 0 and plug them for t. This way you will get values for d. Since your answer is 3, you don't have a lot to plug in and calculate. Then make a graph where t is on the x-axis and d is on the y-axis. According to your d values you can make intervals of 10s, 20s or even 100s. Lastly just plot your data.

According to projections through the year 2030, the population y of the given state in year x is approximated by
State A: - 5x+y=11,400
State B: -143x +y = 9,000
where x = 0 corresponds to the year 2000 and y is in thousands. In what year do the two states have the same population?
Answer:
In the year 2026 population of both the states will be the same.
Step-by-step explanation:
It has been given in the question that the population y of State A in year x will be represented by the equation
-3x + y = 11,400
⇒ y = 11,400 + 3x --------(1)
Similarly, an equation that represents the population for State B is
-138x + y = 8,000
⇒ y = 138x + 8,000 -------(2)
If population y for both the states are equal then
3x + 11,400 = 138x + 8,000
11400 - 8000 = 138x - 3x
135x = 3400
x = 25.19 [After 25 years ]
Since x = 0 represents the population of the states in the year 2000
therefore, population y will be the same in both the states in the year (2000 + 26)
= 2026
