2. W"(4,-2), X"(1,-2), Y"(1,-4), Z"(4,-4)
RULE:
- If reflected an image over x-axis:
x stay the same, y change.
Ex: A(1,2)>>>x-axis= A'(1,-2)
- If reflected an image over y-axis:
x change, y stay the same.
Ex: B(3,4)>>>y-axis= B'(-3,4)

The baker has 42 kilograms of flour. She uses 8 kilograms each day.after how many days will she need to buy more flour?
Answer:
5 days 6hours
Step-by-step explanation:
Given data
total amount of flour=42kg
number of kg used per day=8kg
Since we are expected to know when she will need more, we need to divide the total flour by the daily usage, to know when the flour we be exhausted
divide 42 by 8 we have
42/8=5.25------0.25 days to hours is 6hours
So it will take 5 days 6hours

In 2012 Staci invested $14,500 in a savings account for her newborn son. The account pays 3.6% interest each year. Determine the accrued value of the account in the year 2030, when her son will go to college. Round your answer the nearest cent.
In the year 2030, the accrued value will be $
Answer: $23,896
Step-by-step explanation:
In the year 2030, the number of years since the investment would be;
= 2030 - 2012
= 18 years.
As the question does not mention that the interest paid is compounded, simple interest will be used;
= Amount + (Amount * interest rate * number of years).
= 14,500 + ( 14,500 * 0.036 * 18)
= $23,896

Step-by-step explanation:
The first aircraft has 89 more seats than the second aircraft. The third aircraft has 45 fewer seats than the second aircraft. If their total number of seats is 401, find the number of seats for each aircraft
Answer: The first aircraft has 208 seats.
The second aircraft has 119 and the third has 74.
Step-by-step explanation:
The equation is x+89 + x + x-45 = 401
combine terms: 3x + 44 = 401 Subtract 44 from both sides 3x=357
divide both sides by 3
x= 119
substitute x in each term of the equation to find the number of seats on each aircraft
119 + 89 = 208 for #1 x= 119 for #2 119- 45= 74 for #3
What value of x is a solution to the equation?
X - 2 = 16 (1 point)
A. 14
B. 18
C. 21
D. 12
Answer:
B. 18
Step-by-step explanation:
we need to isolate x to find the solution
x -2 +2 = 16 + 2
x = 18
The state of Minnesota covers an area of 51 million acres, while the state of Vermont covers 6 million acres. How many times larger is the state of Minnesota as compared to Vermont
Answer: 8.5

(a) x – 5 = 6 (b) 2x + 5 = 7 (c) 2(x – 2) + 6 = 0 (d) 3x + 5 = 4
Answer:
c) 2(x-2)+6=0
2(x-2)+6=0
Distribute
2x - 4 + 6 = 0
Combine like terms -4 + 6
2x + 2 = 0
Subtract both sides
2x = -2
Divide both sides
x = -1
The Johnson family income is
estimated to be $125,000 per year. Mary wanted to write this number
in scientific notation. If she wrote
1.25 x 10" , what value of n should
she use?
Answer:
The value of n would be 5
Step-by-step explanation:
This is understanding how to take numbers and writing them in scientific notation.
125,000 = 1.25 x 10⁵
First of all.
125,000 = 125,000.0 (See that decimal point?)
We want that decimal point behind the number 1 as seen in the scientific notation. All you have to do is move that decimal point to the left until you reach the ones place.
125000. → 1.25
(You're not finished yet)
Since we moved the decimal five times, then we must put an exponential value of 5 above the 10
In conclusion:
125,000 = 1.25 x 10⁵
Courtney needs to find 2,495 ÷ 48. In which place should she write the first digit of the quotient?
Answer:
On the inside of the "box" (long division).
Step-by-step explanation:
Whenever you are dividing, the first quotient goes inside the "box", and the second quotient goes on the outside.
(I am not sure what the symbol is called, that is why I called it a box.)

In the following diagram which is not drawn to scale, why can't both line AB and line AC be perpendicular to line BC?
Answer:
AC and AB both can't be perpendicular to line BC because if they were, then AB and AC would be parallel to each other and would never intersect. In this diagram, AB and AC intersect, so it it not possible.
Perpendicular lines meet at a right angle.
AB and AC cannot be perpendicular to BC because AB and AC are not parallel
From the diagram, we can see that line AB and line AC intersects at point A.
This means that both lines are not parallel
For any two lines to be perpendicular to a third line, the two lines must be parallel to each other.
So, we can conclude that:
Lines AB and AC cannot be perpendicular to line BC because both lines are not parallel.

The Air Quality Index, or AQI, measures how polluted the air is in your city and assigns a number based on the quality of the air. Over 100 is “Unhealthy”.
The following quadratic regression equation gives us an estimate of n, which is the number of days the AQI exceeded 100 a particular year. We will use this equation to estimate the number of days the AQI was over 100 in the year 1995.
n = 1.76 t squared minus 13.32 t + 41.00
(Let t represent the number of years since 1990. Therefore, t = 0 corresponds to the year 1990. For the estimate of n, round to the nearest whole day.)

Graph 1
coordinates : (0,-5) (-6,-2)
m = (y2-y1)/(x2-x1)
m = (-2-(-5))/(-6-0)
m = 3/-6 = -1/2
Substitute the values,
y = mx + c
-2 = (-1/2)(-6) + c
-2 = 3 + c
c = -5
Thus, equation is y = -1/2x -5
Graph 2
coordinates : ( 4,-2) (-5,3)
m = (y2-y1)/(x2-x1)
m = (3-(-2))/(-5-4)
m = 5/-9
Substitute the values,
y = mx + c
-2 = (-5/9)(4) + c
-2 = -20/9 + c
c = 2/9
Thus, the equation is y = -5/9 + (2/9)
