Write the equation of the line parallel to 4x - y = 5 and passes through (3, 4)
Answers
Answer:
Equation of the line parallel to 4x - y = 5 and passes through (3, 4) is
[tex]y=-4x+16[/tex]
Step-by-step explanation:
Slope of line 4x - y = 5 is -4. Since parallel lines have same slopes therefore slope of other line is -4 as well.
Equation of the line that passes through (3, 4) and has slope -4 is given as
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-4=-4(x-3)[/tex]
Simplifying it further
[tex]y=-4x+12+4[/tex]
[tex]y=-4x+16[/tex]

16n−16
Answers
Answer:
16(n-1)
Step-by-step explanation:
16(n-1) is the simplest form of 16n-16 because you cannot backtrack any farther. To get to 16n-16, you must have 16(n-1) first. When you distribute, you will have 16n and -16. Put those into an equation, you get 16n-16 which is what you have originally.

- When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.
Equation at the end of Step 1:
[tex]y=\frac{-7}{x-(-4)}+(-8)[/tex]2.) Simplify the d and k forms:[tex]y=\frac{-7}{x-(-4)}+(-8)=y=\frac{-7}{x+4}-8[/tex]Note:
- The x(d) changes from [tex]x-(-4)[/tex] to [tex]x+4[/tex] because of the 2 negatives rule: When there is 2 negatives next to each other, it automatically changes to being the positive version of of that number or the sum of the 2 numbers.
- The y(k) changes from [tex]+(-8)[/tex] to [tex]-8[/tex] because when a [tex](+)[/tex] and [tex](-)[/tex] are next to each other, the rule is [tex]+<-[/tex]. The Minus always wins in this type of problem situation.
So the answer is b, [tex]\bold{y=\frac{-7}{x+4}-8}[/tex].

A car approaches a stop sign going 10 m/s before coming to a stop. If it takes 5 seconds to
do this, what is its acceleration
Answers
Answer:
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
Step-by-step explanation:
Given
Initial velocity u = 10 m/sFinal velocity v = 0Time taken t = 5 secondsTo determine
Acceleration a = ?
Using the formula to determine the acceleration
a = (v - u) / t
substituting u = 10 m/s, v = 0 and t = 5
a = (0 - 10) / 5
a = -10 / 5
a = -2 m/s²
Thus,
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.

Paul, Fiona and Pip share some sweets in the ratio 4:5:1. Paul gets 15 more sweets than Pip.
How many sweets does Fiona get?
Answers
Answer:
Fiona gets 25 sweets
Step-by-step explanation:
System of Equations
Paul, Fiona, and Pip have some sweets in the ratio 4:5:1. Let's call x,y, and z the number of sweets they have respectively.
The ratios can be written as three separate equations:
[tex]\frac{x}{y}=\frac{4}{5}\qquad\qquad[1][/tex]
[tex]\frac{y}{z}=\frac{5}{1}\qquad\qquad[2][/tex]
[tex]\frac{x}{z}=\frac{4}{1}\qquad\qquad[3][/tex]
Paul has 15 more sweets than Pip, then:
x = z + 15 [4]
Multiplying [3] by z:
x = 4z
Substituing in [4]
4z = z + 15
Subtracting z:
3z = 15
z = 15/3 = 5
Multiplying [2] by z:
y = 5z = 5*5 = 25
Fiona gets 25 sweets

Given: Kristen made 4 out of 5 throws in her first basketball game, 5 out of 8 in her second game and 5 out of 7 free throws in her third game.
To Find: The experimental probability of Kristen marking her first free throw in her fourth game.
Solution:
There are only two possibilities that the first throw will be free or not.
Hence, the total outcomes = 2
Hence, Probability that the throw is free = [tex]\frac{1}{2}[/tex]
Hence, 1/2 is the experimental probability of Kristen marking her first free throw in her fourth game.

Nicky wants to surround a painting 5 inches by 11 inches with a frame that is w inches wide. Write a quadratic function A in standard form to represent the combined area A of the picture and the frame.
A(w) = w2 + w +
Answers
Answer:
Since the frame is uniform around the picture, you need to add its width, W, to the sides of the picture. We will manipulate the formula for area, A = L x W. To ease confusion with the chosen variable, I will replace the W with an H for height to be A = L x H.
L = W + 11 + W
H = W + 5 + W
You can see this by drawing a picture with a frame around it. Looking from the top to the bottom, you will have it's width plus the picture plus the width of the frame again. Same thing for the height of the picture. Looking from the far left of the frame and across, you have the width of the frame plus the picture plus the width of the frame again. Now plug these into the area formula and combine like terms.
A = L x H
A = (W + 11 + W) x (W + 5 +W)
A = (2W + 11) x (2W + 5)
Now take the product of the two parenthesis.
I learned to use the FOIL method: multiply First, Outside, Inside, Last.
A = (2W x 2W) + (2W x 5) + (11 x 2W) + (11 x 5)
A = 4W2 + 10W + 22W + 55
A = 4W2 + 32W + 55
Step-by-step explanation:
The quadratic function A in standard form to represent the combined area A of the picture and the frame is 4w²+32w+55.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
Nicky wants to surround a painting 5 inches by 11 inches with a frame that is w inches wide.
Then, the width of the painting
w = 5 + w + w
=2w+5 (w inches wider on both sides)
and, the length of the painting
l = 11 + w + w = 2w+11
So, the area is
Area = length x width
= (2w+11)(2w+5)
=4w²+22w+10w+55
= 4w²+32w+55

Answer:

Substitute any coordinate into the equation y= -1x + c
eg. (6,3) (x,y)
x=6 and y=3
3 = -1(6) +c
3= -6 + c
Rearrange to make c the subject
C= 3+6 = 9
