you are saving money for a new iPhone. You've already save $249 and you make nine dollars per hour at work. How many hours, (h), must you work to have enough money to buy a $699 iPhone? Which inequality models this situation?
Answer: about 78 hours if you round up the answer!
Step-by-step explanation:
Answer:
$249 + 9h > $699Step-by-step explanation:
We will start with $249 and then add the inequality for h. Note that the number can be larger than 699, but not lower.
$249 + 9h > $699(3x^4-12x^3-5x^2-18+8) (x+4)

Ten less than half of a number(x) is 6.
Answer:
x = 32
Step-by-step explanation:
Given the following data;
Unknown number = x
Translating the word problem into an algebraic equation, we have;
[tex] \frac {x}{2} - 10 = 6[/tex]
Lowest common denominator (LCD) = 2
We multiply all through by 2;
[tex] 2* \frac {x}{2} - 2*10 = 2*6[/tex]
[tex] x - 20 = 12[/tex]
[tex] x = 12 + 20[/tex]
x = 32
Therefore, the unknown number is 32.

- 1/2 - 2/3v = 4/5 please help
Answer:
v = - [tex]\frac{39}{20}[/tex]
Step-by-step explanation:
Given
- [tex]\frac{1}{2}[/tex] - [tex]\frac{2}{3}[/tex] v = [tex]\frac{4}{5}[/tex]
Multiply through by 30 ( the LCM of 2, 3 and 5 )
- 15 - 20v = 24 ( add 15 to both sides )
- 20v = 39 ( divide both sides by - 20 )
v = - [tex]\frac{39}{20}[/tex]
Answer:
[tex]v=-\frac{39}{20}[/tex]
Step-by-step explanation:
Given the expression
[tex]-\frac{1}{2}-\frac{2}{3}v=\frac{4}{5}[/tex]
Add 1/2 to both sides
[tex]-\frac{1}{2}-\frac{2}{3}v+\frac{1}{2}=\frac{4}{5}+\frac{1}{2}[/tex]
[tex]-\frac{2}{3}v=\frac{13}{10}[/tex]
Multiply both sides by 3
[tex]3\left(-\frac{2}{3}v\right)=\frac{13\cdot \:3}{10}[/tex]
[tex]-2v=\frac{39}{10}[/tex]
Divide both sides by -2
[tex]\frac{-2v}{-2}=\frac{\frac{39}{10}}{-2}[/tex]
[tex]v=-\frac{39}{20}[/tex]
Therefore,
[tex]v=-\frac{39}{20}[/tex]

Bcuz, some thing's power 0is 1
According to the zero power rule of exponents, 3^0 = 1. The statement 3^0 ≠ 1 is FALSE.
What is the Zero Power Rule of Exponents?The zero power rule is a property of exponents which simply states that whatever base that is raised to the power of zero would always be equal to one, i.e., x^0 = 1.
We are given that 3^0 ≠ 1. Based on the zero power rule of exponents, this is FALSE because 3^0 = 1.

The sum of two numbers is 46. The difference of those numbers is 22. What are the two numbers?
Answer:
34 and 12
Step-by-step explanation:
so two numbers are x and x-22
then x+x-22=46
2x=68
x=34
x-22 = 12
The numbers are 34 and 12, which gives sum 46 and difference 22.
What is algebra?Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.
Let the two numbers are a and b.
According to given conditions,
The sum of a and b is 46,
And the difference of a and b is 22.
Implies that,
a + b = 46 (1)
a - b = 22 (2)
Add equation (1) and (2),
2a = 68
a = 34
Substitute the value of a in equation 1 to get the value of b,
34 + b = 46
b = 46 - 34
b = 12
The required numbers are 34 and 12.

Diego measured the length of a pen to be 22 cm. The actual length of the pen is 23 cm. Which of these is closest to the percent increase or decrease for Diego's measurement?
Answer: 4.5%
Step-by-step explanation:
From the question, we are informed that Diego measured the length of a pen to be 22 cm while the actual length of the pen is 23 cm.
The percentage decrease in his measurement will be:
= (23 - 22)/22 × 100
= 1/22 × 100
= 4.5%

FIND THE NUMBER OF SUBSETS FOR SET
A) CONTAINING 3 ELEMENTS
B) WHOSE CARDINAL NUMBER IS 5
Answer:
a) 8 subsets
b) 32 subsets
Step-by-step explanation:
The total number of subset of a set is known as the power of the set
Power of a set is expressed as;
P = 2^n
n is the number of element in the set
a) For a set containing 3 elements
n = 3
Power of the set = 2³
Power of the set is 8
This means that the set contains 8 different subsets
b) Cardinality of a set is the total number of element in the set
If the cardinal number of a set is 5, this means that the set contains 5elements
Hence the power of the set will be;
P = 2^5
P = 32
Hence the total number of subset for set whose cardinal number is 5 is 32

Explain why the expression below always has the same value, no matter what number other than zero you choose for p.
P-2P+3p-4P
---------------
P
Answer and explanation:
The expression P-2P+3P-4P cannot have the same values for different values of P. Let us illustrate this by substituting different values of P in the expression:
If P= 2
Substitute P=2 in the expression
2-2×2+3×2-4×2
=2-4+6-8
=-4
If P= 3
Substitute P=3 in the expression
3-2×3+3×3-4×3
=3-6+9-12
=-6
If P = 1
Substitute P=1 in the expression
1-2×1+3×1-4×1
= 1-2+3-4
= -2
If P = -2
Substitute P=1 in the expression
-2-2×-2+3×-2-4×-2
= -2+4-6+8
=4
Therefore we can see from the above that the expression has different values for different values of P

Answer:
-(r+8)
Step-by-step explanation:
Write the solution set in interval notation.
First, you need to solve the inequalities.
[tex]4q\geq -16[/tex]
[tex]q\geq -4[/tex]
[tex]q+3<7[/tex]
[tex]q<4[/tex]
Now let's write the interval notation for the first one.
The lowest number for this would be -4. q cannot be less than negative -4. Since q can be -4 OR greater than, you use brackets. [-4,
q can be anything greater than -4. So the second number is infinity. Infinity uses parentheses because it is no exact number.
So the interval notation for the first inequality is [-4, ∞).
Now let's write the interval notation for the second one.
q can be anything less than 4. So the first number would be negative infinity: (-∞
q cannot pass 4, so the second number would be 4. Since q does not include 4, you use parentheses: 4)
The interval notation for the second inequality is (-∞, 4).
The interval notation for this compound inequality is [-4, ∞) or (-∞, 4).

Write an equation of the line in point-slope form y-y_1=m(x-x_1) from the given point and slope.
(4,6); m=2
Answer:
The equation in point-slope form is [tex]y-6=2(x-4)[/tex].
Step-by-step explanation:
We are given the slope and a coordinate pair of a line.
Slope: 2Coordinate Pair (x, y): (4, 6)Therefore, we can now label our coordinate pair and substitute our values into the formula. Our formula is:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
We can label our coordinate pairs with the [tex](x_1, y_1)[/tex] labeling method.
Therefore, since our two coordinates are:
x = 4y = 6We can label 4 as x₁ and 6 as y₁.
Then, we are able to determine m, or our slope.
m = 2Now, let's set up our equation.
[tex]\displaystyle y - y_1 = m(x - x_1)\\\\y - 6 = 2(x - 4)\\\\y - 6 = 2x - 8\\\\y = 2x - 2[/tex]
Therefore, our line is y = 2x - 2. However, the problem asks for it in point-slope form. So, this is exactly what we have in Step 2: y - 6 = 2(x - 4).

What is 5X - 5 distributive property
Answer: 5(x-1)
Step-by-step explanation:
5*x = 5x
5*-1 = -5
therefore the answer is 5(x-1)
5x-5 distributed is 5(x-1).
The common factor of 5x and 5 is 5.
5x divided by 5 is 1x or x.
5 divided by 5 is 1.
So the answer is 5(x-1).
