What is the coordinates after (x+2, y + 3)
Answer:
L is (2,4) M (3,1,) N(0,4)
Step-by-step explanation:
L 0+2=2 so x is 2
L 1+3=4 so y is 4
M 1+2=3 so x is 3
M -2+3=1 so y is 1
N -2+2=0 so x is 0
N 1+3=4 so y is 4
What value of b completes the function f(x)=-x^2+bx+1?
Answer:
Step-by-step explanation:
It is hard to guess the coordinates of any points, because the graph doesn't go through any intersections of the grid.
Fortunately, I can tell that the axis of symmetry is x=2.
Put the equation into vertex form by completing the square.
axis of symmetry = b/2
b/2 = 2
b = 4
Finding missing angle. PLEASE HELP ME!
Answer:
x=147°
Step-by-step explanation:
1. Analyze: The angle opposite to the 33 degree angle is 33 degrees because they are vertical angles.
2. Make an equation: The sum of all four angles (x, the angle opposite of x, the 33 degree angle, and the angle opposite of the 33 degree angle) is 360°. Therefore the equation would be (33°x2)+2x= 360°.
3. Solve for x:
a. Multiply 33 by 2
66+2x=360
b. Subtract 66 from both sides
66+2x=360
-66 -66
2x=294
c. Divide both sides by 2
[tex]\frac{2x}{2} =\frac{294}{2}[/tex]
x=147
4. Remember to add your label- the degree sign (°)
x=147°

Match the factors affecting cost to their definitions. Write the name of the factor next to its definition
Answer:
cost of materials - the value of all things needed to create the good or service
opportunity cost - the value of a product given up to produce or obtain another product
fixed cost - costs that are not affected by the level of production
sunk cost - past costs that cannot be recovered
marginal cost - change in total cost that arises when the quantity produced changes by one unit
Step-by-step explanation:

1 kilogram of baking soda costs $4.5
Step-by-step explanation:
To solve this problem, we will follow the steps bellow:
Using proportion;
Let x be the cost of 1 kg of baking soda
kilogram = $ 2
1 kilogram = x
Cross - multiply
× x = $2 × 1
× x = $2
= $2
Multiply both-side of the equation by 9
× 9= $2 × 9
At the left-hand side of the equation 9 will cancel-out 9, hence our equation becomes
4x = $18
Divide both-side of the equation by 4
= $
x = $4.5
1 kilogram of baking soda costs $4.5

. Express the ratios in its simplest form (a) 15:12 (b) 42:1
Find the value of "x" in the following 2:x :: 4:6
Answer:
See answers below
Step-by-step explanation:
Given the following ratios. We are to express them in their simplest forms
15:12
= 15/12
= (3*5)/(3*4)
= 3/3 * 5/4
= 5/4
b) 42:1
= 42/1
= 42
Given that 2:x :: 4:6
2/x = 4/6
Cross multiply
4x = 2*6
4x = 12
x = 12/4
x = 3
Hence the value of x is 3
Classmates Joan, Peta, and Linda each received $400 as graduation gift. Joan deposits her money in an account that earns 7% interest compounded annually and keeps the money in the account for three years. Peta deposits her money, plus an extra $70, in an account that earns 8% interest compounded annually and keeps the money in the account for two years. Linda deposits her money in an account that earns 5% compounded'annually and keeps the money in the account for one year.
Who has more money when they close their accounts and why?
A) Joan, because she kept her money in the longest.
B) Linda, because of her interest rate.
C) Peta, because she invests the most.
D) They all make the same amount.
9514 1404 393
Answer:
C) Peta, because she invests the most
Step-by-step explanation:
The additional $70 that Peta invests is equivalent to more than 2 years' interest at either of the other rates. Not only does Peta invest more money, she does so at a higher interest rate.
Peta will have the most money in her account when she closes it.
__
The balances will be ...
Joan $490.02
Peta $548.21
Linda $420.00

what's the answer! Consider having a personal loan that spans 5 years. The loan was only taken out for $6000, but the interest rate was a higher fixed percentage of 5.99%. How much interest will you have paid after it is paid off?
Answer: $179.70
Step-by-step explanation:
The simple interest will be:
= (Principal × Rate × Time) / 100
= ($6000 × 5.99% × 5) / 10
= ($6000 × 0.0599 × 5) / 10
= $1797 / 10
= $179.70
Therefore, the total interest on the loan is $179.70
50 points!!!! Assuming all parabolas are of the form y = ax^2+ bx + c, drag and drop the graphs
to match the appropriate a-value.
Answer:
Step-by-step explanation:
a > 0 for an up-opening parabola, so a = 0.25 for the third graph.
The greater the magnitude of a, the skinnier the parabola.
|-1| < |-4|, so a = -4 for the first graph.
Jack collected 18 ten dollar bills while selling tickets for a show. He gave 1 over 6 of the bills to the theater and kept the rest. How much money did he keep?
Answer:
150
Step-by-step explanation:
Collected bills: 18 * 10= 180
1/6 of 180 = 30
180-30=150
Answer:
15 ten dollar bills, 150 dollars
Step-by-step explanation:
1/6 of 18 is 3, so he gave 3 bills to the theater and kept the other 15 for himself

There are two squares.ONe has a side length of 12 inches and the other has a side length of 14 inches.What is he total area of both squares?
Answer:
340 in^2
Step-by-step explanation:
1. First square
A = l*w = 12^2 OR 12*12 = 144
2. Second square
A = l*w = 14^2 OR 14*14 = 196
3. Combined Area
144+196=340
The area of a square is found by squaring the side length, which is the same as multiplying two of the sides together.
Square 1: 12 x 12 = 144 square inches.
Square 2: 14 x 14 = 196 square inches.
Total area = 144 + 196 = 340 square inches.
