complete the equation of the line whose y-intercept is (0, -1) and the slope is 4
Answer:
y=4x-1
Step-by-step explanation:
We know that the slope equation is y=mx+b. M is the slope and B is the y-intercept. M is provided to be 4 and B is provided to be -1, so all we have to do is plug them in to get the answer.
Answer:
y = 4x - 1
Step-by-step explanation:
Slope-intercept form:
y = mx + b
So, input all the values...
y = 4x - 1

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

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.

The decimal 4.6 is the same as what fraction?
Answer:
23/5
is the 4.6 fraction
The decimal 4.6 is equivalent to the fraction 23/5.
The whole number part of the decimal, which is 4, will be the numerator of the fraction.
The decimal part, which is 0.6, will be the numerator of the fraction divided by the appropriate power of 10.
In this case, the decimal has one digit after the decimal point, so we divide it by 10¹.
0.6 / (10¹)
= 0.6 / 10 = 6/10
Simplify the fraction if possible.
Both the numerator and denominator can be divided by their greatest common divisor, which is 2 in this case.
6/10 = (6/2) / (10/2) = 3/5
Therefore, the decimal 4.6 is equivalent to the fraction 4 3/5 or simply 23/5 after simplification.

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP
The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so
cost = price + 0.1*price
cost = 1.1 * price
price = cost / 1.1
price = 22 / 1.1 = 20
now we need 20% of that so that's

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:

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.

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
