Answer:
Step-by-step explanation:
1) a) equations: 3x+21 and 6x -60
b) value of x: 3x+ 21=6x-60 ( set them equal to each other because they are equal, then solve)
3x+21=6x-60
-3x=-81
x= 27
c) replace 27 in both equations to find the angle measure.
3(27)+21= 102
6(27)-60= 102
2) a) equations: 12x-18 and 8x+10
b) value of x: 12x-18=8x+10( set them equal to each other because they are equal, then solve)
12x-18=8x+10
4x=28
x= 7
c) replace 7 in both equations to find angle measure.
12(7) -18 = 66
8(7)+10= 66
angle measure: 66
3) a) equations: 7x+9 and 5x+3
b) value of x: to find value of x here, first know that the these two equations will add up to 180. So, set them up to be equal to 180.
7x+9+5x+3=180
Then solve.
12x+ 12=180
12x=168
x=14
c) angle measure: replace the 14 in the x of the two equations.
7(14) +9 = 107
5(14) +3= 73
add the two angle measure together to see if they add up to 180.
107 + 73 = 180 correct! :D

There are approximately 40,000 people that live in a city. A sample of 20,000 people from that city are asked and 8,000 live in an apartment.
How many people from the entire population would you expect to live in an apartment?
Answer:
16,000 people
Step-by-step explanation:
Let's write a ratio
8,000:20,000
Let's write another ratio
x:40,000
We can write a percent proportion.
[tex]\frac{8,000}{20,000} =\frac{x}{40,000}[/tex]
We can see that the relationship between the denominators is multiplied by 2 so that means the relationship between 8,000 and x is x is 2 times greater than 8,000
Let me know if you have any questions.
Answer:
16000
Step-by-step explanation:
Mika wrote the table of points of ...
X Y
0 2
3 5
6 8
What explains whether or not Mika has described a proportional relationship.
Answer:
She described a proportional relationship because for each X value there is a Y value, So if X marks 1, you add 1 to Y, being the starting value of Y 2
For the table prepared by the Mike, he has "not" described a proportional relationship.
What is Proportionality?Equivalence between two ratios in algebra is called proportionality. A and B are in the same ratio as C and D in the formula a/b = c/d.
Step 1: Calculation for the slope of the points:Table prepared by Mike is,
X Y
0 2
3 5
6 8
The ratio of the y-to-x value differential between two locations, as seen on a two-dimensional plane.
[tex]\frac{5-2}{3-0} =\frac{8-5}{6-3} =\frac{8-2}{6-0} =1[/tex]
Since, the slope is the same, the relationship is linear.
Step 2: Check for proportional relationship.The function is said to be linear if we plot these points on a line and obtain a straight line. If this line passes through point (0,0), the connection will be proportional.
Equation of line passing through two points is obtained by,
=> y-b = m(x-a)
Consider point (0,2)
=> y-2 = 1×(x-0)
As, y = x+2, is equation of linear function.
Step 3: Checking whether the line passes through origin (0,0)LHS, at ,(0,0) = 0
RHS at (0,0 )= 0+2=2
LHS≠RHS
Therefore, even though the supplied points add up to a linear function, there is no proportional relationship.

I'll do problem 1 to get you started.
The answer to problem 1 is 3400 miles
============================================================
Explanation for problem 1:
We're asked to find the perimeter, which is the total distance around the exterior or outside. In other words, we need to add up the four side lengths of this quadrilateral.
We'll need the distance formula to find the lengths of the slanted sides AB and BC
----------------------------------------
Let's first find the length of segment AB
A = (x1,y1) = (0,0)
B = (x2,y2) = (400,300)
d = Length of AB
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-400)^2 + (0-300)^2}\\\\d = \sqrt{(-400)^2 + (-300)^2}\\\\d = \sqrt{160000 + 90000}\\\\d = \sqrt{250000}\\\\d = 500\\\\[/tex]
The distance from A to B is 500 miles. This is the same as saying segment AB is 500 miles long.
----------------------------------------
Now find the length of segment BC
B = (x1,y1) = (400,300)
C = (x2,y2) = (-800,800)
d = length of BC
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(400-(-800))^2 + (300-800)^2}\\\\d = \sqrt{(400+800)^2 + (300-800)^2}\\\\d = \sqrt{(1200)^2 + (-500)^2}\\\\d = \sqrt{1440000 + 250000}\\\\d = \sqrt{1690000}\\\\d = 1300\\\\[/tex]
----------------------------------------
The length of CD is fairly easy to find without needing the distance formula. This is because it is a vertical line. We subtract the y coordinates of C and D to get 800-0 = 800. So CD is 800 miles long.
Segment DA is a similar story. But we subtract the x coordinates. This only works for horizontal lines. DA is 800 miles long because |-800-0| = 800. Absolute value is used to make sure the distance is never negative.
----------------------------------------
To summarize everything so far, we found these four side lengths
AB = 500BC = 1300CD = 800DA = 800The perimeter is going to be the sum of those four sides, leading to...
perimeter = sum of sides
perimeter = AB+BC+CD+DA
perimeter = 500+1300+800+800
perimeter = 3400 miles
This is the total distance traveled if you started at city A, went to B, then to C, then to D, and then finally went back to A.
Answer:
The total distance is 3400 miles
Step-by-step explanation:
Given the following points:
A(0,0)
B(400,300)
C(−800,800)
D(−800,0)
we can find the distance between each of them using the following equation:
d(X,Y)=
√(x2
−x1
)2
+(y2
−y1
)
2
in this case, we only need to find the distance from A to B and from B to C:
d(A,B)=
√(400−0)2
+(300−0)2
=
√160000+90000
=
√250000
=500
d(B,C)=
√(−800−400)2
+(800−300)2
=
√1440000+250000
=
√1690000
=1300
next, notice that the distance from C to D and from D to A are on lines parallel to the x-axis and the y-axis, then, we can see that the distances are the follwing:
d(C,D)=800
d(D,A)=800
then, the total distance traveled will be the perimeter of the polygon, Thus, adding the distances we have:
P=d(A,B)+d(B,C)+d(C,D)+d(D,A)=500+1300+800+800
=3400
⇒P=3400miles

You need 112 K-cups for a party. A box of K-cups costs $16 for 36 K-cups. What is the minimum amount of money you will spend?
Answer:
$49.60
Step-by-step explanation:
The equation setup I used for this was as follows: $16 x (112/36)
Using PEMDAS, you'd start with the division part, 112/36. Although, I did this a bit differently, and being a bit further in school, I don't know if you go through this where you're at.
Start by factoring 112 into 4(28). This leaves you with 4(28)/36.
Next, cancel 4 out of 36. Since 4 is the common factor in 28 and 36, you cancel the four out of the equation, leaving you with 28/9. Convert this to its decimal form, 3.1.
Finally, take the 3.1 and multiply that by $16, which comes out to $49.60.

write y=-2x^2-20x-52 in vertex form then find the axis of symmetry. show your work!
Answer:
Simplifying
y = 2x2 + 20x + 52
Reorder the terms:
y = 52 + 20x + 2x2
Solving
y = 52 + 20x + 2x2
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 52 + 20x + 2x2

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?
Answer:
$8,900
Step-by-step explanation:
You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.
Here i = $8,000*0.075*1.5 (representing 18 months)
i + $900
At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.
Answer:
$8,900
