Answer:
y = ¹/₂x + 6Step-by-step explanation:
The product of slopes of perpendicular lines is -1
y = - 2x + 6 ⇒ m₁ = - 2
m₁m₂ = -1
-2m₂ = -1
m₂ = ⁻¹/₋₂ = ¹/₂
The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)
m = ¹/₂
(-2, 5) ⇒ x₁ = -2, y₁ = 5
So the equation in point-slope form:
y - 5 = ¹/₂(x - (-2))
Therefore:
y - 5 = ¹/₂x + 1
y = ¹/₂x + 1 + 5
y = ¹/₂x + 6-9 + p/2= -13
(two step equations, show your work)
Answer:
p=−8
Step-by-step explanation:
Regroup terms.
p /2 −9=−13
Add 9 to both sides.
p/2 =−13+9
Simplify -13+9 to −4.
p/2=−4
Multiply both sides by 2.
p=−4×2
Simplify 4×2 to 8
p=−8.

Answer:
width= 4
hieght- 5.65
Step-by-step explanation:
so first lets find the diestnce between 0,0 and 4,4
which is 4 root 2
which is approciamitlty 5.65 and this would be the hieght
the width would be 22.64/5.65= approxiamitly 4

How would you express the area of the rectangle using the Distributive Property?
Answer:
C
Step-by-step explanation:
Step 1: Find your legth and width
Length = x + 5
Width = 3
Step 2: Use area formula to find area
l x w = A
(x + 5) x 3 = A
A = 3(x+5)
Step 3: Therefore Statement
Thereforethe answer to the question is C. 3(x+5)
Answer:
C. 3(x + 5)
Step-by-step explanation:
area of rectangle = length * width = width * length
A = area of largest rectangle
a1 = area of left rectangle
a2 = area of right triangle
The largest rectangle is made up of the the two smaller rectangles.
A = a1 + a2
Left rectangle: a1 = WL = 3x
Right rectangle: a2 = WL = 3 * 5
Total area of the two small rectangles:
A = a1 + a2 = 3x + 3 * 5
Apply the distributive property in reverse to 3x + 3 * 5 by factoring out a 3:
A = 3x + 3 * 5 = 3(x + 5)
The area of the largest rectangle is 3(x + 5)
We can also find an expression for the area of the largest rectangle directly by looking at its length and width.
The length of the largest rectangle is x + 5.
The width of the largest rectangle is 3.
A = WL
Substitute 3 for W, the width.
Substitute x + 5 for L, the length.
A = 3(x + 5)
Answer: C. 3(x + 5)
Suppose cos(x)=-1/3, where pi/2≤x≤ pi. What is the value of tan(2x)?
Answer:
4√2/7
Step-by-step explanation:
Suppose cos(x)=-1/3, where pi/2≤x≤ pi
tan(2x) = sin(2x)/cos(2x)
Since sin2x = 2sinx cosx
cos 2x = 2cos²x-1
Substitute
tan(2x) = 2sinx cosx/ 2cos²x-1
Given cosx = -1/3
adjacent = -1
hyp = 3
opp = √3²-(-1)²
opp = √9-1
opp = √8
sinx = opp/hyp
sinx = √8/3
tan(2x) = 2sinx cosx/ 2cos²x-1
tan(2x) = 2(√8/3)(-1/3)/ 2(-1/3)²-1
tan2x= (-2√8/9 )÷ (2/9 - 1)
tan2x = -4√2/9 * 9/-7
tan 2x = 4√2/7

A cell phone provider offers a plan that costs $20 per month plus $0.20 per text message sent or received. A comparable plan costs
$30 per month but offers unlimited text messaging. Complete parts a. and b. below.
a. How many text messages would have to be sent or received in order for the plans to cost the same each month?
In order for the plans to cost the same.
text messages would have to be sent or received
b. If you send or receive an average of 200 text messages each month which plan would you choose and why?
Answer:
Step-by-step explanation:
a)
30=20+0.2m
10=0.2m
50=m
So after sending 20 messages the plans would cost the same.
b)
Obviously from the first part that the unlimited plan is cheaper when sending 200 messages, but the costs numerically would be.
Unlimited plan costs $30 while the other plan costs
20+0.2(200)=$60

Question 5(Multiple Choice Worth 4 points)
(05.05)David and Amanda are trying to figure out how long they can live off their $12,350 savings if they spend $240 each month. They have each created an equation.
David’s Equation Amanda’s Equation
y = 12,350 – (240x) y = 12,350 + (240x)
Which person has the correct equation to model this linear relationship?
Amanda’s equation is correct, because their spending will be multiplied by the number of months and then added to their savings.
Amanda’s equation is incorrect, because their spending will increase the amount of their savings.
David’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.
David’s equation is incorrect, because their spending should be a fixed amount and should not be multiplied.

Prompt Explain how new technologies like machine guns, airplanes, tanks, and poison gas led to so many million deaths during World War I.
Might Help:
The machine gun and the tank were new technologies that influenced WW1 the most. The machine gun lengthened the war and forced it to become a trench war. The bullets in a machine gun could shoot 500 bullets per minute therefor making it much more difficult for the rivalry county to fight back.

Answer:
70 degrees
Step-by-step explanation:
The exterior angle in a triangle is equal to the sum of the two opposite interior angles
So,
the two interior angles in the question are U and T while the exterior angle is V.
Using this,
U+T =V
U+50 = 120
(make U the subject of formula)
U = 120 - 50
U = 70 degrees

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
A spinner with six section numbered from 1 to 6.
total number of times spins = 150
So, the number of times the number comes less than 5 is
= 150 x 1/5
= 150/5
= 30
