Are the graphs of y = -2x + 4 and y = (1/4)x -2 parallel, perpendicular, or neither? *
Answers
Answer: Neither
Step-by-step explanation:
For this to be paralell it would need to have the same slope. (They don't have the same.) For this to perpandicular it would have to reciporcal ( Ex: -2 reciporcal would -1/2 or 1/4 reciprocal would have to be 4)
Answer:
neither
Step-by-step explanation:
For two lines to be parallel, their slopes must be equal.
For two lines to be perpendicular, their slopes must have a product of -1. (The only exception is a vertical line and a horizontal line which are perpendicular, but the product of their slopes is not -1.)
When the equation of a line is written in the slope-intercept form,
y = mx + b,
m is the slope.
y = -2x + 4 has a slope of -2.
y = (1/4)x -2 has a slope of 1/4.
Clearly, -2 and 1/4 are not equal, so the lines are not parallel.
Now we find the product of the slopes.
(-2) * (1/4) = -2/4 = -1/2
The product of the slopes does not equal -1, so the lines are not perpendicular.
Answer: neither

Ahmed owns a land of breadth (x+7) units &having an area of 2+ 14x + 49 sq. Units. (i)Find its length.
Answers
Answer:
l = (x+7) units
Step-by-step explanation:
Given that,
Breadth of the rectangle, b = (x+7) units
Area of the rectangle, [tex]A=x^2+14x+49[/tex]
The area of a rectangle is given by :
[tex]A=lb\\\\l=\dfrac{A}{b}\\\\l=\dfrac{(x^2+14x+49)}{(x+7)}\\\\l=\dfrac{(x+7)^2}{(x+7)}\\\\l=(x+7)\ \text{units}[/tex]
So, the length of the land is (x+7) units.
Erin buys a bag of peanuts that weighs 3/4 of a pound later that week the bag is 2/3 full how much dose the bag of panuts wiegh now
Answers
Answer:
1 ÷ 2 pounds
Step-by-step explanation:
The computation is shown below:
As we know that
1 pound = 0.454 Kg
Peanut starting weight = 3 ÷ 4 of a pound.
In the case when the bag is 2/3 full, so the weight is

Step-by-step explanation:
∵ circumference of circle = 2πr = m
∴ r = m/2π
∵ area of circle = πr²
∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π

A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remainder when that number is divided by 35?
Answers
Answer:
zero
Step-by-step explanation:
The computation of the remainder when the number would be divided by 35
Let the number be x
So if x is divided by 5 gives the remainder 0
x = 0
And, if x is divided by 7 gives the remainder 0
x = 0
So if x is divided by 35 so the remainder is also zero

y = -4/5x + -9
I only know that first one sry
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
slope intercept form is y=mx+b
b is the y intercept, m is the slope, and x is x.
for
1. it would be
y= -4/5x -9
2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)
it would look like:
(5- -3) / (3-0) = (8/3)
Then plug in one of the sets of numbers for x and y, to get y intercept.
5=8/3(3)+b
b=-3
So.. slope intercept would be y=8/3x -3

Mimi = 9/10 of a punnet of strawberries
Jamie has four times as many strawberries as Mimi
Jamie = 9/10 × 4
= (9×4) / 10
= 36/10
= 3 6/10
= 3 3/5 of a punnet of strawberries
Jamie = 3 2/5 of a punnet of strawberries

What is the coefficient in the expression 4x + 2
O2
O4
Ox
O+
Answers
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
The 2 and + are out since they don't have variables(and the + is just a +).
So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.
