What is the value of t in the equation?
-3t – 4 (t – 5) = 48
Step-by-step explanation:
-3t-4t+20=48
-7t=28
t=-4
Answer:
t = -4
Step-by-step explanation:
-3t – 4 (t – 5) = 48
Distribute
-3t -4t +20 = 48
Combine like terms
-7t +20 = 48
Subtract 20 from each side
-7t +20-20 = 48-20
-7t = 28
Divide by -7
-7t/-7 = 28/-7
t = -4

What are the solutions of 16p^2 - 64 = 0
Answer:
p = 2 or p = -2
Step-by-step explanation:
Solve for p over the real numbers:
16 p^2 - 64 = 0
Hint: | Factor constant terms from the left hand side.
16 p^2 - 64 = 16 (p^2 - 4):
16 (p^2 - 4) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 16:
p^2 - 4 = 0
Hint: | Using the quadratic formula, solve for p.
p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:
Answer: |
| p = 2 or p = -2Solve for p over the real numbers:
16 p^2 - 64 = 0
Hint: | Factor constant terms from the left hand side.
16 p^2 - 64 = 16 (p^2 - 4):
16 (p^2 - 4) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 16:
p^2 - 4 = 0
Hint: | Using the quadratic formula, solve for p.
p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:
Answer: |
| p = 2 or p = -2Solve for p over the real numbers:

16 (p^2 - 4) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 16:
p^2 - 4 = 0
Hint: | Using the quadratic formula, solve for p.
p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:

How do i make 2 ( x + 3 ) into a no solution problem?
Answer:
By making x = -3
Step-by-step explanation:
If X was -3 then -3 plus 3 equals 0, and 2 multiplied by 0 is 0, so the problem will have no solution.

Shelley wants to purchase a cell phone package, which includes a free phone. The cost of the package is $0.10 per minute, for the number of minutes she uses the phone, plus a base rate of $89.00.
Answer:
The function would be linear because the rate of change is constant.
Step-by-step explanation:
Given
[tex]Base= \$89.00[/tex]
[tex]Rate = \$0.10[/tex] per minute
See attachment for complete question and options
First, we write the function that calculates the cost (C(t)) for t minutes.
This is calculated as:
[tex]Cost = Base + Rate * t[/tex]
[tex]C(t) = 89.00 + 0.10 * t[/tex]
[tex]C(t) = 89.00 + 0.10t[/tex]
Rewrite as:
[tex]C(t) = 0.10t + 89.00[/tex]
A function that has the above format is referred to as a linear function which has the general format
[tex]f(x) = mx + b[/tex]
Where
m represents the slope/rate and it is constant
From the list of given options, (a) is correct.

14d - 22 + 5d = 12d - 8
Answer:
d = 2
Step-by-step explanation:
14d - 22 +5d = 12d - 8
19d -22 = 12d - 8
+22 +22
19d = 12d + 14
-12d -12d
7d = 14
/7 /7
d = 2
Answer:
d = 2
Step-by-step explanation:
Simplifying
14d + -22 + 5d = 12d + -8
Reorder the terms:
-22 + 14d + 5d = 12d + -8
Combine like terms: 14d + 5d = 19d
-22 + 19d = 12d + -8
Reorder the terms:
-22 + 19d = -8 + 12d
Solving
-22 + 19d = -8 + 12d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-12d' to each side of the equation.
-22 + 19d + -12d = -8 + 12d + -12d
Combine like terms: 19d + -12d = 7d
-22 + 7d = -8 + 12d + -12d
Combine like terms: 12d + -12d = 0
-22 + 7d = -8 + 0
-22 + 7d = -8
Add '22' to each side of the equation.
-22 + 22 + 7d = -8 + 22
Combine like terms: -22 + 22 = 0
0 + 7d = -8 + 22
7d = -8 + 22
Combine like terms: -8 + 22 = 14
7d = 14
Divide each side by '7'.
d = 2
Simplifying
d = 2

Determine whether the lines are parallel, perpendicular, or neither.
y = 3x - 2
-3x + y = 8
Answer:
they are parallels
Step-by-step explanation:
they have the same slope but different y intercepts so they are parallel
Answer:
Parallel
Step-by-step explanation:
First, you should put the second equation in slope-intercept form, it would be y=3x+8.
If two lines are parallel they will have the same slope. If two lines are perpendicular the slopes will be the negative reciprocals of each other. The slopes of these two lines are the same so they are parallel.
Braden's credit card balance was $162. If
he charges $54 then makes a $75 payment,
find the balance on his card.
Answer:the answer is 33
Step-by-step explanation:
The balance on the credit card will be $33.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Braden's credit card balance was $162. He charged $54 then makes a $75 payment the balance amount will be calculated as below:-
Balance = 162 - 75 - 54
Balance = 162 - 129
Balance = $33
Therefore, the balance on the credit card will be $33.

Answer:
a).cruz is right.
b).-64 is cube root of -4.
c).because -64 is square root of -8.
Step-by-step explanation:
1.Cruz is right
2. If the nth root of the negative number is a odd number, the answer is negative this of the FOLLOWING is the example not the answer
[tex] \sqrt[5]{ - 243} = [/tex]
[tex]( - 3 \times - 3) = 9[/tex]
[tex]9 \times ( - 3) = - 27[/tex]
[tex] - 27 \times - 3 = 81[/tex]
[tex]81 \times - 3 = - 24 3[/tex]
So the answer is -3
For -64
[tex] - 4 \times - 4 = 16[/tex]
[tex]16 \times - 4 = 64[/tex]
So Cruz is right.
3. Aaron is wrong because it asked for the 3rd root of -64 and -8 isn't that.
Jacob is wrong because the nth root is a odd number and the number under the radical s negative so it going to give us a negative number(which is a real number)

Choose the equation of a line parallel to the graph of 2y - 6x = 8.
a
y = - x + 1
b
y = 3x + 5
c
y = - 3x + 4
d
y = - 1/3x + 4
Answer-A
Step-by-step explanation:
Reason- in order to have two lines be parallel they must have the same slope, in this case the slope has to be 3x. If you look at A it is 2y=6x+8 and to graph it, y has to be by itself. so you divide both sides by two making it y=3x+4, and as you can see it now has a slope of 3x.

O The domain is all real numbers such that -3 sxs1,
and the range is all real numbers less than or equal to

O The domain is all real numbers, and the range is all
real numbers less than or equal to 4.
O The domain is all real numbers less than or equal to
4, and the range is all real numbers.
Answer:
Step-by-step explanation:
This equation is y=4-(x+1)^2, there is no restriction upon x and y has a max value of four and approaches negative infinity as x moves away from -1 in either direction. So the domain is all real numbers and the range is all real numbers less than or equal to four.
The domain and range of the quadratic function are:
Domain: Set of all real numbers.Range: y ≤ 4.How to get the domain and range?
For a function y = f(x), we define the domain as the set of the possible inputs x, and the range is the set of the possible values y.
On the graph, we can see a quadratic function.
For the domain, we usually start assuming that the domain is the set of all real numbers, and then we remove problematic points. Where a problematic point can be a zero on a denominator or something like that.
In the case of a quadratic, there are no problematic points, then the domain is the set of all real numbers.
For the range, we can see that the function has a maximum at y = 4, and then it goes down, so the range is just:
R: y ≤ 4.
