Answer: Choice A. y + 5 = -2(x + 2)
================================================
Explanation:
Let's solve the given equation for y so we can find the slope.
3x - 6y = 2
3x = 2+6y
3x-2 = 6y
6y = 3x-2
y = (3x-2)/6
y = (3x/6) - (2/6)
y = (1/2)x - 1/3
The last equation is in y = mx+b form. We see that m = 1/2 is the slope.
Apply the negative reciprocal to go from 1/2 to -2/1 or just -2.
The original slope is 1/2, and the perpendicular slope is -2.
Rule: multiplying any two perpendicular slopes leads to -1 where neither line can be vertical.
Let's plug in m = -2, x1 = -2 and y1 = -5 into point slope form
y - y1 = m(x - x1)
y - (-5) = -2(x - (-2))
y + 5 = -2(x + 2)
Write the equation of the line that passes through the points

Answer:
We conclude that the area of the right triangle is:
[tex]A\:=p^2-2p-3[/tex]
Hence, option A is correct.
Step-by-step explanation:
From the given right-angled triangle,
Base = p+1Perpendicular = 2p-6Using the formula to determine the area of the right-angled triangle
Area of the right triangle A = 1/2 × Base × Perpendicular
[tex]=\frac{1}{2}\left(p+1\right)\left(2p-6\right)[/tex]
Factor 2p-6: 2(p-3)
[tex]=\frac{\left(p+1\right)\times \:2\left(p-3\right)}{2}[/tex]
Divide the number: 2/2 = 1
[tex]=\left(p+1\right)\left(p-3\right)[/tex]
[tex]\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]
[tex]=pp+p\left(-3\right)+1\cdot \:p+1\cdot \left(-3\right)[/tex]
[tex]=pp-3p+1\cdot \:p-1\cdot \:3[/tex]
[tex]=p^2-2p-3[/tex]
Therefore, we conclude that the area of the right triangle is:
[tex]A\:=p^2-2p-3[/tex]
Hence, option A is correct.
Jerry was given some birthday money. He puts the money in an account. Every month after that, he deposits the same amount of money.
The equation that models this situation is y = 50x + 75, where y is the amount of money in the account and x is the number of deposits.
What does the y-intercept mean in this situation?
A. He was given $50 for his birthday.
B. He puts $75 in the account each month.
C. He puts $50 in the account each month.
D. He was given $75 for his birthday.
The y -intercept in this situation mean that Jerry was given $75 for his birthday
The equation below is a linear equation.
y = 50x + 75
A linear equation is an equation that has a single variable raised to the power of 1. 50x is raised to the power of 1
75 represents the constant. This is the money he deposited in the account. 75 is the y-intercept. The y-intercept is the value of the line y when it crosses the y-axis
50x is the slope of the line. - 50 is the amount he puts in every month and x represents month.
The slope of a line also known as the gradient of the line determines the steepness and direction of a line. If the slope coefficient is less than zero, the slope is negative and it would decline from left to right
y is the dependent variable. It is the total amount he would have at the end of each month. y depends on the constant term (75), the number of months(x) and the amount he deposits every month (50)
at the end of :
one month, he would have : 50(1) + 75 = 125
two months, he would have : 50(2) + 75 = 175

Answer:
a₃₀ = - 18
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = a₂ - a₁ = 10 - 11 = - 1, then
[tex]a_{n}[/tex] = 11 - (n - 1) = 11 - n + 1 = 12 - n , thus

rohan wants a field in the shape of trapezium . its side along the pond is parallel to and double the side along the road .Area of the field is 10200sqm.What is the length of the side along the river?
plss answer, will mark u the brainlliast
Answer:
The length of side along the river is 68 m
Step-by-step explanation:
Area of trapezium = 10200 m²
Length of side along the road (a) = x
Length of side along the river (b) = 2x
Height = 200 m
We need to find Length of side along the river.
The formula used is: [tex]Area\: of\: trapezium=\frac{a+b}{2}\times h[/tex]
Putting values and finding length:
[tex]Area\: of\: trapezium=\frac{a+b}{2}\times h\\10200=\frac{2x+x}{2}\times 200\\10200=2x+2\times 100\\\frac{10200}{100} =2x+2\\102=3x\\x=\frac{102}{3}\\x=34[/tex]
So, Value of x = 34
Length of side along the road (a) = x = 34
Length of side along the river (b) = 2x = 2(34) = 68
So, the length of side along the river is 68 m
A soccer player uses her head to hit a ball up in the air from a height of 2 meters with an initial vertical velocity of 5 meters per second. The height h in meters of the ball is given by \large h=-4.9t^2+5t+2 , where t is the time elapsed in seconds. How long will it take the ball to hit the ground if no other players touch it?

Answer:
y = 4x - 4
Step-by-step explanation:
to write a linear equation you need to know 2 components: slope and y-intercept
find slope by selecting 2 points, for example, (1,0) and (2,4)
slope ('m') = difference of y-values 4 - 0 = 4
difference of x-values 2 - 1 1
to find y-intercept ('b'), plug values into the slope-intercept form of a line, which is:
y = mx + b
you need a point and the slope of 4/1; can use any point
we'll use (2,4) where x =2 and y=4 and, again, m = 4
4 = 2(4) + b
4 = 8 + b
-4 = b

but he paid only 65% of the retail price. How much did
Alexander's new glasses cost him?
A
$88.35
$108.55
$100.20
none of these
Alexander's new glasses cost would be the amount of $108.55 which is the correct answer would be an option (B).
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have been given that Alexander's new glasses normally cost $167 at a retailer, but he only paid 65% of the retail cost.
To determine the amount his new glasses cost
We have to calculate 65% of $167 which is the retail cost.
As per the given information, the solution would be:
⇒ 65% of $167
⇒ (65/100)(167)
⇒ (0.65)(167)
⇒ 108.55
Therefore, his new glasses cost would be the amount of $108.55.

Anna and Jose bought a pizza and ate 5 of the 8 slices. Zach and Sarah came over and Anna split the remaining slices evenly between them. How would you determine the fraction of the original pizza that Zach and Sarah each ate?
Answer:
24/2 slices
= 12/1
Step-by-step explanation:
Total slices of pizza = 8
Anna and Jose ate = 5
Slices of pizza remaining = 3
Zach and Sarah came over and Anna split the remaining slices evenly between them
That's is, 3 slices of pizza divided by 2 people
= 3/2
= 1 1/2 slices each
Each of Zach and Sarah ate 3/2 slices of pizza
fraction of the original pizza that Zach and Sarah each ate
= 3/2 of 8
= 3/2 × 8
= 24/2
= 12/1

A worker is stacking boxes.One stack has boxes that are 2 inches high. The other stack has boxes that are 5 inches high. At what height will the two stacks of boxes be equal in height?
Answer:
10 inches.
Step-by-step explanation:
One stack has boxes that are 2 inches high, then the height of this stack can be only multiples of 2 inches.
The other stack has boxes that are 5 inches high, then the height of this stack can be only multiples of 5 inches.
The height of both stacks will be the same for all the common multiples of 2 and 5.
Because 2 and 5 are prime numbers, all the common multiples between 2 and 5 will be direct products of these two numbers.
Like 2*5 = 10
is both a multiple of 2 and 5 (is the first common multiple)
Then we can use stacks of 10 inches.
Such that, for the stack where each box is 2 inches high, we need:
10in/2in = 5
5 boxes.
And for the stack where each box is 5 inches high, we will need:
10in/5in = 2
2 boxes.
