Answer:
B. y= -2x+3
Step-by-step explanation:
1) the slope-interception form is: y=s*x+i, where s - slope, i - interception are unknown numbers;
2) if y(0)=3, then i=3, it means the equation is y=s*x+3;
3) if to substitute x=1; y=1 into the equation y=s*x+3, then s= -2. It means, the initial equation is y= -2x+3.
4) finally, the correct answer is B.

Answer: undefined
This is because the x value is 5, which means that there is no horizontal movement of the line. So therefore, the line is vertical. And vertical lines have an undefined slope.

Give the slope values that are parallel and perpendicular to a slope of 1/4.
Answers
Step-by-step explanation:
Finding the Slopes of Parallel and Perpendicular Lines
How do we know if two distinct lines are parallel, perpendicular or neither? To make that determination, we need to review some background knowledge about slope.
Concept 1: When two points are given, the slope of a line can be algebraically solved using the following formula:
Slope Formula
The slope,mm, of a line passing through two arbitrary points \left( {{x_1},{y_1}} \right)(x
1
,y
1
) and \left( {{x_2},{y_2}} \right)(x
2
,y
2
) is calculated as follows…
m = (ysub2-ysub1)/(xsub2-xsub1)
Concept 2: When a linear equation is given, we can find the slope by transforming it into the Slope-Intercept Form. The value of slope will stand out, as it is the coefficient of the linear term (xx-term).
Slope-Intercept Form of a Line
The linear equation written in the form y = mx + by=mx+b is in slope-intercept form where:
m is the slope, and b is the y-intercept
Now, suppose we have two distinct and nonvertical lines, {\ell _1}ℓ
1
and {\ell _2}ℓ
2
in Slope-Intercept Form.
Line 1:
line 1 → y=msub1x+b
Line 2:
line 2 → y = msub2x+b
Parallel Lines: The lines are parallel if their slopes are equal or the same. That means
Equal Slopes:
msub1 = msub2
Graph:
graph showing line 1 and line 2 parallel on the coordinate plane.
Perpendicular Lines: The lines are perpendicular if their slopes are opposite reciprocals of each other. Or, if we multiply their slopes together, we get a product of - \,1−1. These lines intersect at a ninety-degree angle, 90°.
Opposite Reciprocal Slopes:
msub1 = -(1/msub2)
Product of Slopes:
msub1× msub2 = -1
Graph:
graph showing line 1 and line 2 perpendicular to each other on the coordinate plane.
Examples of How to Find the Slopes of Parallel and Perpendicular Lines
Example 1: Line 1 passes through the points \left( {1,3} \right)(1,3) and \left( {4,9} \right)(4,9), while line 2 passes through \left( {2,5} \right)(2,5) and \left( { - \,2, - \,3} \right)(−2,−3). Tell whether these lines are parallel, perpendicular, or neither.

Nayeli is driving on a long road trip. She currently has 14 gallons of gas in her car. Each hour that she drives, her car uses up 1.5 gallons of gas. How much gas would be in the tank after driving for 4 hours? How much gas would be left after t hours?
Answers
Answer:
8 gallons
Step-by-step explanation:
Total gas in the car = 14 gallons
Each hour gas usage = 1.5 gallons
Total hours traveled = 4 hours
Left gas after 4 hours
= 14-1.5(4)
=14-6
=8 gallons
Left gas after t hours
=14-1.5t
Hence the answer is after 4 hours, 8 gallons are left after t hour(s) 14-1.5t
The amount of gas in the tank after driving for 4 hours will be 6 gallons. The amount of gas that is left after t hours will be 14 - 1.5t.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Nayeli is driving on a long road trip. She currently has 14 gallons of gas in her car. Each hour that she drives, her car uses up 1.5 gallons of gas.

For this exercise we must correct the error of the given fraction, differentiating the properties of addition and multiplication, so:
1)This error occurs frequently because when simplifying in a multiplication or division it cannot be done in the operations of subtraction and addition.
2)As this error is very common, it has probably already occurred. But one way to resolve this is to pay attention and redo the math.
to understand this error we have to:
[tex]\frac{(3)(5)}{3} = 5[/tex]
In the case of multiplication the 3 of the numerator can be simplified with the 3 of the denominator, the other case will be:
[tex]\frac{3+5}{3} = \frac{8}{5}[/tex]
In the case of addition or subtraction, you should always keep the denominator.

A fast-food restaurant was selling 7 boxes of chicken nuggets for $25.90. A competing restaurant was selling 3 boxes of chicken fingers for $11.07. Which food has a higher unit price? Answer:
Answers
Answer:
The competing company is better
7 for 25.90 vs. 7 for 25.83
Step-by-step explanation:
Since it's 3 for 11.07
we need to see how much higher the price will get at 7, so divde 11.07 by 3 then double the price.
3.69 per box for competing company
11.07*2 = 22.14
22.14 + 3.69= 25.83

Answers
Answer:
-23
Step-by-step explanation:
h+11.5=-11.5
h=-11.5-11.5
h=-23
you will subtract -11.5 on both sides which leaves h alone on one side
Step-by-step explanation:
subtract 11.5 from both side of equation
h + 11.5 = -11.5
h + 11.5 - 11.5 = -11.5 - 11.5
h + 0 = -23
h = -23

Answer:
£67.87
Step-by-step explanation:
(Total increase) = (Original Amount) × (Multiplier)²
Rearrange the equation to find the original amount
(Total increase) ÷ ( Multiplier)² = (Original amount)
To find the Multiplier, add 1 to 3% = 1.03
Substitute what you can
(72) ÷ (1.03)² = Original amount
£67.8669054576 = Original Amount
Round up the number to 2 decimal places since it is British Pounds currency
£67.87 = Original Amount
