Answer:
Equation of a straight line is given as y = mx+c
m = slope or gradient or dy/dx or y2 - y1/ x2 - x1
c = intercept
y = 2x - 7
y = -x + 1
y = 2x - 10
Step-by-step explanation:
Using y = mx+c
A. m=2 y=-7 x=0
-7= 2*0 + c
-7=c
y = 2*x - 7
y = 2x - 7
B. x1=3 x2=-2 y1=-4 y2=1
m = y2 - y1/ x2 - x1
m = 1+4 / -2-3
m = 5/-5 which is equal to -1
using any value for y and x, let's use x1 and y1
-2 = -1*3 + c
-2 = -3 + c
1 = c
y = -1*x + 1
y = -x + 1
C. x1=6 x2= 5 y1= 2 y2=0
m = y2 - y1/ x2 - x1
m = 0-2 / 5-6
m = -2/-1 which is equal to 2
using any value for y and x, let's use x1and y1
2 = 2*6 + c
2 = 12 + c
-10 = c
y = 2*x -10
y = 2x - 10

Welcome to another new game show, “Spinning for Luck!” As a contestant, you will be spinning two wheels. Each wheel is divided into equal sectors. The first wheel determines a possible dollar amount that you could win. The second wheel is the “multiplier”. You will multiply the results of your spins to determine the amount you will win. Unfortunately, you could owe money if your multiplier lands on –2!
a. What is the probability of winning $100 or more?
b. What is the probability of owing $100 or more?
Answer a ) 25%
Answer b ) 8.33%
The following formula can be used to determine the likelihood of both winning and owing $100 or more:
a. ) Chance of winning at least $100:
On the first wheel, there is a 2/6 = 1/3 chance of landing in a sector that equates to $100 or more.
On the second wheel, there is a 3/4 chance of landing on a multiplier other than -2.
The odds of both happening are (1/3) * (3/4) = 1/4 or 0.25.
The likelihood of earning $100 or more is thus 0.25, or 25%.
b. ) Likelihood of having at least $100 in debt:
The odds of landing on a sector with a value on the first wheel that is less than or equal to -$50 are 2/6 = 1/3.
A landing on a -2 multiplier on the second wheel has a 1/4 chance of happening.
1/12, or 0.08333, is the likelihood that both occurrences will occur (1/3) * (1/4).
Thus, the likelihood of owing $100 or more is 0.08333, or around 8.33%.
Therefore the final answer is 25% and 8.33%.

Answer this question: -12d- 6= -2(d+3)- 10d
Answer:
d = 1
Step-by-step explanation:
-12d - 6 = -2 (d + 3) - 10d
-12d - 6 = -2d - 6 - 10d
-12d - 6 = -12d - 6
-12d = -12d

Lisa hikes 9 miles in 2 hours. At this rate, how far does she hike in
1/6
hours?
Answer:
72 miles
Step-by-step explanation:
Answer:
0.75 or 3/4 miles hiked in 1/6 hours
Step-by-step explanation:
2 hours = 120 minutes
1/6 x 60 = 10 minutes
9 / 120 = 0.075 miles per minute
10 x 0.075 = 0.75
The linear function y = 15x represents the distance y (in miles) you have traveled after x hours
during a 4-hour bicycle ride.
Which graph represents the situation?
Answer:
The graph to in the top right
Graph B, represents the situation.
What is a linear function?A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra. The only difference is the function notation. Knowing an ordered pair written in function notation is necessary too. f(a) is called a function, where a is an independent variable in which the function is dependent. Linear Function Graph has a straight line whose expression or formula is given by;
y = f(x) = p x + q
Given linear function:
y = 15x
where y is distance in miles
x is time in hours.
Graph A only represents the points and not the linear function.Graph B represents the linear function.putting the value (4,60) in given linear function,
y = 15x
⇒ 60 = 15 × 4
⇒ 60 = 60
Graph C and Graph D has no scale for x variable; the time in hours, hence do not represent the situation.Hence, by the above observation, Graph B represents the linear function, y = 15x.

two triangles with corresponding congruent angles are congruent. Is this statement true or false?
Answer:
FALSE
Step-by-step explanation:
For two triangles to be considered congruent to each other, their corresponding angles and their corresponding side lengths must be congruent to each other. That is all the sides and angles of one triangle must be equal to all the corresponding sides and corresponding angles of the other.
Therefore, knowing that two traingles have corresponding angles that are equal is not enough to conclude that they are congruent. It simply means they have the same shape, but may not have the same size, as their corresponding sides may vary.
Thus, the statement, "Two triangles with corresponding congruent angles are congruent" is FALSE.

Answer:
d. 7 and 16; 8 :14,4:7 and 16:28.
Answer:
D. 7 and 16; 8 : 14, 4 : 7, and 16 : 28
Step-by-step explanation:
1. the first ratio for 8 and 14 is 4 : 7. so that would eliminate the first two answer choices.
2. since the ratio is 4 : 7, that would mean the second value for buses is 7 because the second value for taxis is 4. and the second values for both taxis and buses would be equal to the ratio.
3. 28 is the third value for the bus. and since the ratio is 4 : 7, you have to find the value that 7 can be multiplied by to get 28. 7 multiplied by 4 is 28. you also have to multiply the first number of the ratio (4) by 4. and the product would be 16.
4. So the final answer is D.
How would you express the area of the rectangle using the Distributive Property?
A rectangle with length x plus 5 and width 3.
A. 5(x + 3)
B. x(3 + 5)
C. 3(x + 5)
D. 3x + 5
Answer:
The area of the rectangle can be found using two different expressions: a(b + c) or ab + ac. The equality of these expressions, a(b + c) = ab + ac, is the distributive property.
The expression that shows the length and width of the rectangle in distributive format is 3(x + 5) = 3x + 15 and this can be determined by using the distributive property.
Given :
A rectangle with length x plus 5 and width 3.
The distributive property is given by:
a(b + c) = ab + ac
The above expression is known as the distributive property. Where a, b, and c represents the three different variables.
So, according to the given data, the length of the rectangle is (x + 5) and the width of the rectangle is 3.
The expression shows the length and width of the rectangle in distributive format.
3(x + 5) = 3x + 15
The above expression also represents the area of the rectangle.
Therefore, the correct option is C).
