Which of the following equations represents a line that is perpendicular to the line represented by x + 2y = 6 and passes through the point (3 , –4)?
Answer:
y=2x-10
Step-by-step explanation:
First change to equation into slope intercept form
2y=-x+6
y=-1/2x+3
slope=2 (beacause it is perpendicular)
y--4=2(x-3)
y+4=2x-6
y=2x-10
What is the slope of a line that passes through the points (-3, 2) and (-6, 5)?
A. -3
B. -1
C. 1/3
D. 1
Write the equation of each circle
Center (-1,0) and containing the point (2, -4)
A.(x + 1)2 + y2 = 25
B.x2 + (y2 +1)= 25
Answer:
The equation of the circle is [tex](x + 1)^2 + y^2 = 25[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle of centre [tex](x_c,y_c)[/tex] has the following format:
[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]
In which r is the radius.
Center (-1,0)
This means that [tex]x_c = -1, y_c = 0[/tex]. So
[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]
[tex](x - (-1))^2 + (y - 0)^2 = r^2[/tex]
[tex](x + 1)^2 + y^2 = r^2[/tex]
Finding the radius:
Distance between the radius and the centre and a point of the circle. In this case, point (2,-4). Using the formula for the distance between two points:
[tex]r = \sqrt{(2-(-1))^2+(-4-0)^2} = \sqrt{3^2 + 4^2} = \sqrt{25} = 5[/tex]
So, the equation of the circle is:
[tex](x + 1)^2 + y^2 = 5^2[/tex]
[tex](x + 1)^2 + y^2 = 25[/tex]

Randy bought 3 identical shirts and paid a sales tax of $2.84. The total cost was $50.18. What was the cost of each shirt?
Answer:
$15.78
Step-by-step explanation:
I) Remove tax:
$50.18 - $2.84 = $47.34
II) Construct an equation to find the cost of each shirt:
47.34 = 3s
III) Solve:
Divide each side by 3:
15.78 = s
Each shirt costed $15.78
Answer:
15.78
Step-by-step explanation:
Lyn either travels by bus or walks
when she visits the shops.
The probability that she catches
the bus To the shops is 0.2
The probability that she catches
the bus FROM the shops is 0.6
0.2
Walk
a) Complete the tree diagram.
b) Show that the probability that Lyn
walks at least one way is 0.88.
I’m forced to write an explanation, sorry for the useless text
The probability tree has been drawn below and the probability that Lyn
walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks.
What is probability?The probability of an event occurring is defined by probability.
Do not take underestimate probability it has several uses in daily life whether forecasts like that.
As per the given probability tree,
(a)
The probability in branches adds to 1 thus,
0.2 + probability that she walks to the shop = 1
Probability that she walks to the shop = 1 - 0.2 = 0.8
The probability in the same branches multiplies as,
The probability that she took a bus to the shop x from the bus she again took the bus.
Similarly, the tree diagram has been drawn below.
(b)
The probability is 0.88 lies in that Lyn walks at least one way 0.88 is when she reaches the shop by bus and from the bus, she walks.
Hence "walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks".

What is the equation of 35?
35 - X = 5
Simplifying
35 + -1X = 5
Solving
35 + -1X = 5
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-35' to each side of the equation.
35 + -35 + -1X = 5 + -35
Combine like terms: 35 + -35 = 0
0 + -1X = 5 + -35
-1X = 5 + -35
Combine like terms: 5 + -35 = -30
-1X = -30
Divide each side by '-1'.
X = 30
Simplifying
X = 30

To investigate whether or not sending text messages while driving impacts driving ability, we had 100 participants (50 men and 50 women) drive an obstacle course under one of the following conditions: 1) no texting while driving, 2) sending five text messages while driving, or 3) sending 10 text messages while driving. We measured the accuracy with which the subjects drove the obstacle course from a scale of 1 to 10 (1 = poor and 10 = excellent).We are testing the effect of sending text messages at three different _____.
a. treatments
b. levels
c. factors
d. None of the above
Answer:
A - treatments
Step-by-step explanation:
We are told the 100 participants were required to drive under 1 of the 3 conditions below which are;
- no texting while driving.
- sending five text messages while driving
- sending 10 text messages while driving
In experimental a research, these 3 conditions are referred to as treatments because they are used to derive an experimental result.
