1. 2x + 1 ≤ 3
2. 1 + 3x ≥ -5
3. 5x - 7 ≥ 17
4. 5 - 3x ≥ 11
Step-by-step explanation:
Ok
5x - 7 ≥ 17
subtract 7 and u get 5x ≥ 10
divide that and you get ≥ 2
so 3 goes with that one
1 + 3x ≥ -5
subtract 1 and you get 3x ≥ -6
divide that and youll get x ≥ -2
so 2 goes with this one
2x + 1 ≤ 3
subtract 1 and u get 2x ≤ 2
divide them and you get x ≤ 1
so 1 goes with this one
5 - 3x ≥ 11
subtract 5 and u get -3x ≥ 6
divide it and u get x ≥ -2
so 4 goes with this one

Please help! if abcd is dilated by a factor of 3, the coordinate of b would be
Answers
Answer:
(-6, 6)
Step-by-step explanation:
The coordinates of B to start with is
(-2, 2)
To dilate this by a factor of 3....
-2 * 3 = -6
2 * 3 = 6
The new coordinates of B' would be
(-6, 6)
A few things to know:
- The number 3 is called a "scale factor"
- Dilation means we are multiplying all the (X, Y)'s by the scale factor
- If the scale factor is greater than 1, the size of the shape overall increases
- If the scale factor is less than 1, the size of the shape overall decreases
- If the scale factor is negative, the shape size stays the same. The shape just rotates 180 degrees and moves to the opposite quadrant.

Which input value produces the same output value for the two functions on the graph?
f)--x1
ot) -x-2

g(x)
Answers
9514 1404 393
Answer:
x = 3
Step-by-step explanation:
Each line shows you the output value for a given input value. If you want a particular input value to give the same output for both functions, then you need to find the point where the lines cross. This question asks for the input value at that point, the x-coordinate.
The lines cross at (x, y) = (3, -1), so x = 3 produces the same output from both functions.

Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale. To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale. How many ounces are in each container of ginger ale?
Answers
Given:
Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale.
To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale.
To find:
The number of ounces in each container of ginger ale.
Solution:
Let n be the number of ounces in each container of ginger ale.
According to the question, the ratio of fruit juice and ginger ale is 2:5. it means,
[tex]\dfrac{\text{Fruit juice}}{\text{Ginger}}=\dfrac{2}{5}[/tex]
[tex]\dfrac{18}{\text{Ginger}}=\dfrac{2}{5}[/tex]
[tex]5\times 18=2\times \text{Ginger}[/tex]
[tex]90=2\times \text{Ginger}[/tex]
Divide both sides by 2.
[tex]45=\text{Ginger}[/tex]
So, ginger required for punch is 45 ounces.
Number of containers = 3
Number of ounces in each container of ginger ale = n
Number of ounces in 3 containers of ginger ale = 3n
Now,
[tex]3n=45[/tex]
Divide both sides by 3.
[tex]n=15[/tex]
Therefore, 15 ounces are in each container of ginger ale.
school lunches cost $14.50 per week. About how much would 5.5 weeks cost of lunches
Answers
Answer:
The answer should be about $81.20
Step-by-step explanation:
$14.50 x 5weeks = $72.50
A school week is usually 5 days.
The middle of the week is Wednesday, so that's 3 whole days.
$14.50 / 5days = $2.90 per day
$2.90 x 3days = $8.70
$72.50 + $8.70 = $81.20

c is your answer
Answer:
B
Step-by-step explanation:
Expanding the products using FOIL , noting that i² = - 1
A
(2x - 4i)(x - 2i)
= 2x² - 4ix - 4ix + 8i²
= 2x² - 8ix - 8 ≠ 2x² + 8
B
(2x - 4i)(x + 2i)
= 2x² + 4ix - 4ix - 8i²
= 2x² + 8 ← True
C
(2x - 2i)(x + 6i)
= 2x² + 12ix - 2ix - 12i²
= 2x² + 10ix + 12 ≠ 2x² + 8
D
(2x + 4i)(x + 2i)
= 2x² + 4ix + 4ix + 8i²
= 2x² + 8ix - 8 ≠ 2x² + 8
Thus
(2x - 4i)(x + 2i) = 2x² + 8 → B

in word for, 5.004 is ____. five thousand, four five and four hundredths five and four thousandths five, four hundredths
Answers
Answer:
In word form, 5.004 is five and four thousandths.
Step-by-step explanation:
The part to the left of the decimal is simple - it's just five.
The part to the right of the decimal is a bit more complicated. The digit one place to the right of the decimal is the tenths place. The digit to the right of the tenths place is the hundredths place. The digit to the right of the hundredths place is the thousandths.
With that in mind, you should find that the number 4 is in the thousandths place. So, your answer is five and four thousandths.

20 balloons have to be devided between a group A and Group B in the ratio 2:3. How many balloons will each group receive?
Answers
Answer:
There are 8 and 12 balloons for groups A and B, respectively.
Step-by-step explanation:
The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:
Group A
[tex]n_{A} = \frac{2}{2+3}\cdot (20)[/tex]
[tex]n_{A} = 8[/tex]
Group B
[tex]n_{B} = \frac{3}{2+3}\cdot (20)[/tex]
[tex]n_{B} = 12[/tex]
There are 8 and 12 balloons for groups A and B, respectively.

Given the figure below, find the values of x and z.
(10x - 65)
(9x - 49)
Answers
(10x - 65) = (9x - 49)
By subtracting 9x in both sides,
(10x - 9x) - 65 = (9x -9x) - 49
x - 65 = -49
By adding 65 in both sides,
x - 65 + 65= -49 + 65
x = 16
Next, to find the value of z, it’s important to know that the straight line has 180 degrees. Then you would substitute the x value you found into one of your equation and subtract it from 180.
10 (16) - 65 = 160 - 65 = 95
Now you know that (10x - 65) degrees is equal to 95 degrees,
180 - 95 = z = 85
Answer: x = 16
z = 85

a graph passes through the points (0,2),(1,3), and (2,4). Does this graph represent a linear function or a non linear function?
Answers
9514 1404 393
Answer:
linear
Step-by-step explanation:
The slope of the line between the first pair of points is ...
m = (y2 -y1)/(x2 -x1)
m = (3 -2)/(1 -0) = 1/1 = 1
The slope of the line between the second pair of points is ...
m = (4 -3)/(2 -1) = 1/1 = 1
The slopes are the same, so the points are on the same line. The graph is that of a linear function.

A 32-ounce package of a snack mix is 24 percent pretzels. How many ounces are pretzels?
0.706 ounces
0.768 ounces
7.06 ounces
7.68 ounces
Answers
Answer:
the correct answer is choice D. if 24 precent of the snack mix is pretzels we simply need to multiply the total number of ounces by 0.24 7.68 ounces of the snack mix will be pretzels
D. 7.68 ounces
Explanation:
What we know:
- the snack mix is 32 ounces
- 24% of the snack mix is pretzels
To find the ounces of pretzels, find 24% of 32 ounces by multiplying them.
24% = 0.24 as a decimal
0.24*32=7.68
Therefore, 7.68 ounces are pretzels.

Brian buys a computer for £3600. It depreciates at a rate of 5% per year. How much will it be worth in 2 years? Give your answer to the nearest penny where appropriate.
Answers
Answer:
£3591
Step-by-step explanation:
Brian buys a computer for £3600. It depreciates at a rate of 5% per year. How much will it be worth in 2 years? Give your answer to the nearest penny where appropriate.
The formula for Depreciation rate =
P = Po × e^-rt
P = Amount after depreciation
Po = Initial amount = £ 3600
r = depreciation rate = 5% = 0.05
t = time in years = 2
Hence:
P = £3600 × e ^ -0.05 × 2
P =£ 3600 × e-0.0025
P = £ 3591.0112406
Approximately = £3591

9 added to twice a number is the same as 27 reduced by 4 times the number
Answers
Answer:
x = 12
Step-by-step explanation:
Let the number be x.
9 added to twice a number is the same as 27 reduced by 4 times the number
If we add 9 to the number = (9+x)
If 27 reduced by 4 times the number = (4x-27)
ATQ,
(9+x) = (4x-27)
Taking like terms together,
x-4x = -27-9
-3x = -36
x = 12
Hence, the number be 12.
