Determine the slope of a line that is Perpendicular to the line that goes
through the points (-3, 8) and (-9,3)
Answer:
slope = - [tex]\frac{6}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 8) and (x₂, y₂ ) = (- 9, 3)
m = [tex]\frac{3-8}{-9+3}[/tex] = [tex]\frac{-5}{-6}[/tex] = [tex]\frac{5}{6}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{6} }[/tex] = - [tex]\frac{6}{5}[/tex]
When looking at graphs, which of the following statements is true about functions? If each vertical line passes through only one point, it is a function. Each vertical line must pass through at least two points to be a function. If there are more than 3 points on the graph it is not a funcion. A function cannot be represented on a graph.
Answer:
If each vertical line passes through only one point, it is a function.
Step-by-step explanation:
The true statement about functions:
-If each vertical line passes through only one point, it is a function.
What is function?"It is a relation between a set of inputs and a set of possible outputs."
What is vertical line?"Any line parallel to the Y-axis"
What is vertical line test?"It is a method that is used to determine whether a given relation is a function or not.""This test states that, any vertical line in the plane can intersect the graph of a function at most once".For given question,
We need to determine where the given graph represents a function or not.
When we look at graphs,
Using vertical line test,

The number of years that Zach has been on the soccer team is 2 less than 5
times the number of years that Anderson has. In total, the boys have been on
the soccer team for 10 years. How long has each boy been on the soccer team?
Answer:
Brad has been on the team for 8 years. Apply that and that means that Anderson has been on the soccer team for 2 years.
Step-by-step explanation:
I dont know how to explain lol i made an equation and figured it out
Step-by-step explanation:
let x be the number of years that Zach has been on the soccer team and y the number of years Anderson has been on the soccer team.
So, reading our problem it seems that
x=5y-2
x+y=10
replacing x on the second formula we take that 5y-2+y=10
6y-2=10
6y=12
y=2
so x=5y-2=5*2-2=10-2=8
Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals negative 3 over 6 units
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals 3 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals 5 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals negative 5 over 6 units

the length of a side of a square is 8x+4.If the perimeter of the square is 80 inches, what is they value of x?
Answer:
Step-by-step explanation:
Note: Perimeter = sum of all the lengths of the shape.
In the case of a square, since all the sides are equal.
This means that if one side = 8x + 4, the perimeter would be 4 times 8x+4 since there are 4 equal sides in a square.
Perimeter = 4 ( 8x + 4)
Perimeter = 32x + 16
We also get told in the question that the perimeter = 80 inches.
Meaning that:
32x + 16 = 80
From here we can solve for x.
Subtract 16 from both sides:
32x = 80 - 16
32x = 64
Divide both sides by 32 to solve for x.
x = 64/32 = 2

A. Rise and equilibrium quantity to rise
B. fall and equilibrium quantity to fall
C. Rise and equilibrium quantity to fall
D. Fall and equilibrium quantity to remain unchanged
Answer: c. Rise and equilibrium quantity to fall
Step-by-step explanation:
The supply curve shows the relationship that exists between the price of a product and the quantity that's been sold by the consumer.
A leftward shift of the supply curve for widgets implies that there's a reduction in the quantity supplied. Since there's a reduction, there'll be few widgets which will lead to increase in equilibrium price and fall in the quantity.

Jasmine needs to solve the equation 9x + 12 = 3(x-8). Which
equations represent a first step Jasmine could use to solve the original
equation? Select all that apply.
Answer:
To find the value of x
1. Solve what it is in the parentheses
2. Combine like numbers on each side of the equation if is possible
3. Subtract 12 on both sides of the equation
4. Subtract 3x on both sides of the equation
5. Divide by 6 both sides of the equation
Step-by-step explanation:
9x + 12 = 3(x-8)
9x + 12 = 3x -24
-12 -12
9x = 3x -36
-3x -3x
6x = -36
6 6
x = -6
The equation that represent the first step that should be required is 9x + 12 = 3x -24.
Calculation of an equation:Since the equation is
9x + 12 = 3(x-8)
So
9x + 12 = 3x -24
6x = -36
x = -6

find the slope and the y intercept 2x+y-2=0
Answer:
Slope: -2; Y-intercept: 2
Step-by-step explanation:
To find the slope, you can rewrite the equation into standard form:
2x+y-2=0
2x+y=2
y=2-2x
The slope is the coefficient of x, which is -2. The y-intercept is the other number, which is 2.
Step-by-step explanation:
gradient= ‐2
y‐ik intercept=2
explanation: rearrange the equation to make y your subject
from the equation , you already know that ‐2 is m (from the equation y=mx +c , whereby m is your gradient) which means ‐2 is your gradient.
from your equation you would also know that 2 is your y‐intercept. also from the equation y=mx+c is your UK intercept

In Hawaii, January is a favorite month for surfing since 60% of the days have a surf of at least 6 feet.† You work day shifts in a Honolulu hospital emergency room. At the beginning of each month you select your days off, and you pick 6 days at random in January to go surfing. Let r be the number of days the surf is at least 6 feet.
Answer:
3 days.
Step-by-step explanation:
Based on the information provided we see that roughly 60% of the days in January have 6ft+ waves then we would need to use this value to calculate the number of days that are good for surfing. We calculate this by multiplying the number of days that you can surf by 60% using the equation below as r being the actual total amount of days....
r = 6 * 0.60%
r = 3.6
As we can see that there are roughly 3 days that see this amount of wave activity between the 6 chosen dates. We have to round down because we are talking about full days and 3.6 does not meet a fourth full day.
Determine the y-intercept of the
equation below. Write your answer as

PLEASE HELP AND SHOW HOW YOU GOT THE ANSWER PLEASEEE
Step-by-step explanation:
Hey there!
The points are; A(-2,3) and B(X,-5). And the distance between them is (√80) units.
We have;
[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]
Keep all values.
[tex] \sqrt{80} = \sqrt{ {(x + 2)}^{2} + {( - 5 - 3)}^{2} } [/tex]
Squaring on both sides.
[tex] { (\sqrt{80}) }^{2} = ( { \sqrt{( {x + 2)}^{2} + ( { - 8)}^{2} } )}^{2} [/tex]
Simplify them.
[tex]80 = ( {x + 2)}^{2} + 64[/tex]
[tex]( {x + 2)}^{2} = 80 - 64[/tex]
[tex]( {x + 2)}^{2} = 16[/tex]
[tex]( {x + 2)}^{2} = {4}^{2} [/tex]
Cancel square from both sides.
[tex]x + 2 = 4[/tex]
X= 4-2
Therefore, X= 2.
The x-coordinate of B is 2.
Hope it helps....
(80)2=((x+2)2+(−8)2)2
Simplify them.
80 = ( {x + 2)}^{2} + 64
80=(x+2)2+64
( {x + 2)}^{2} = 80 - 64
(x+2)2=80−64
( {x + 2)}^{2} = 16(x+2)2=16
( {x + 2)}^{2} = {4}^{2}
(x+2)2=4^2
Cancel square from both sides.
x + 2 = 4
X= 4-2
Therefore, X= 2.
The x-coordinate of B is 2.
