A line is perpendicular to y = {2/3x + 2/3}
and intersects the point (-2, 4).
What is the equation of this
perpendicular line?
y = - x + [?]
Answer: y = (-3x/2) + 1
Step-by-step explanation:
From the standard equation y = mx + c, the slope of the equation is 2/3. Therefor slope of a line perpendicular to it will be -3/2.
Hence the equation will be
y = (-3x/2) + c
As this line passes through (-2,4), putting these values in this equation gives c = 1.
Hence the answer is y = (-3x/2) + 1
PLEASE ANSWER ASAP For the equation y=2x2-16x+30 Identify the vertex and convert into vertex form. STEP BY STEP PLEASE EXPLAIN HOW TO GET THE VERTEX
Answer:
Step-by-step explanation:
To put a quadratic into vertex form, you need to complete the square on it. Do this by following these steps. I'll tell you what we're doing and then show you what it looks like.
First step is to set the quadratic equal to 0 and then move the constant over. That's 2 steps in one, but not confusing at all. That looks like this:
[tex]2x^2-16x=-30[/tex]
Next, the rule is that the leading coefficient has to be a positive 1. Ours is a 2, so we will factor out a 2 but only from the left side. That looks like this:
[tex]2(x^2-8x)=-30[/tex]
Next step is to take half the linear term (the number with the x attached to it, not the x-squared), square it, and add it in to both sides. This is where things get a bit tricky, so pay attention. Our linear term is 8, half of 8 is 4, and 4 squared is 16. So we add 16 in. We'll do it to the left only first:
[tex]2(x^2-8x+16)[/tex]
That's the left side. Notice that there is still a 2 out front there. That 2 is a multiplier. That means that what we actually added in was 2(16) = 32, not just 16. Now adding that to the right makes the whole thing:
[tex]2(x^2-8x+16)=-30+32[/tex]
Completing the square allows us to create a perfect square binomial on the left which is in the form (x - )². That blank space is filled in with the number we squared and then added in. We squared a 4 to get 16, so our perfect square binomial is (x - 4)². Putting that together:
[tex]2(x-4)^2=2[/tex]
Last step is to move the constant back over and set the quadratic back equal to y:
[tex]y=2(x-4)^2-2[/tex]
From here the vertex is apparent. It is (4, -2).
Which graph passes through the point (-5,-6) and has a slope of 2/3 (two over three)

Solve for x: negative 3 over 2, multiplied by x minus 9 equals negative 27 −24 −12 11 12 Btw please show the work bc i not only want the answer, i also want to understand it too
Answer:
[tex]\boxed{ x = 12}[/tex]
Step-by-step explanation:
Given Equation is:
[tex]\frac{-3}{2} (x) - 9 = -27[/tex]
Adding 9 to both sides
=> [tex]\frac{-3x}{2} = -27+9[/tex]
=> [tex]\frac{-3x}{2} = -18[/tex]
Multiplying 2 to both sides
=> -3x = -18 * 2
=> -3x = -36
Dividing both sides by -3
=> x = 12

The initial value of the computer
Explanation:
The v-intercept of the line is the point when the graph goes through the v-axis. At this point, t=0, meaning no time has yet passed. Since no time has passed, the v equals the original value of the computer at the v-intercept, meaning the answer is the initial value of the computer.
Four times the sum of twice a number and 6 is -8. Find the number.
Hey there! :)
Answer:
x = -4.
Step-by-step explanation:
We can write an algebraic equation to express this situation.
Let 'x' represent a number:
4(2x + 6) = -8.
Begin by dividing both sides by 4:
2x + 6 = -2
Subtract 6 from both sides:
2x + 6 - 6 = -2 - 6
2x = -8
Divide 2 from both sides:
2x/2 = -8/2
x = -4.
Answer : -4
Step-by-step explanation:
Let the no. be x
4(2x+6) = -8
8x+24 = -8
8x = -8 - 24
8x = -32
x= -32 / 8
x= -4

The correct answer is 3780 bolts
Explanation:
In one hour the machine can make either 500 nuts or 840. Now, if the machine first made 750 nuts, this means the machine worked 1.5 hours. You can know this using the rule of three:
500 nuts (a) = 1 hour (b)
750 nuts (c) = x (time spent to make 750 nuts)
x = 750 x 1 / 500
x = 1.5
Note: In a rule of three you find the fourth unknown value if you multiply value b by c and divide it by the value a.
According to this, the machine worked 1.5 hours making nuts, and if the machine started at 2 pm, this means the machine ended making nuts at 3.30 pm as 2 pm + 1.5 hours = 3:30 pm (2 + 1.5 = 3.5 ). Now you know the machine made bolts from 3: 30 pm to 8:00 p.m. This means the time the machine made bolts was 4 and a half hours or 4.5 hours (8 - 3.5 = 4.5). At this point, the only missing step is to multiply the time 4.5 hours by the number of bolts the machine makes each hour 840 and this is equivalent to 3780 bolts (840 x 4.5 = 3780).
The variables a and b vary inversely. Use the given values for a and b to write an equation relating a and

Vikas is the head of student council this year at his high school in London. He is responsible for planning the annual graduation trip to Canada's Wonderland. The students will spend one full day at the park and return late that evening. The school has rented a bus for transportation. The entry fee into the park is $50 and the bus costs $600. Write an equation to relate the cost, C, in dollars to the number of student, s, who participate in this fun trip.
Answer:
C = 600 + 50s
Step-by-step explanation:
Let s be the number of students that go on the trip.
Let C be the cost.
The bus costs $600 and the entry fee (for each student) costs $50.
The cost for the trip will be the sum of the cost of the bus and the ticket for every student that goes on the trip.
This implies that the total cost for the trip will be:
C = 600 + 50(s)
C = 600 + 50s

Q1. Calculate the area and perimeter of the following ring where a = 7cm, b = 14cm (i) Area of Ring: (3) (ii) The perimeter of Ring:
Answer:
i) Area of the ring = 462cm²
ii) Perimeter of the ring = 132cm
A complete question related to this found at brainly (ID: 19152996) is stated below:
Calculate the area and perimeter of the following ring where a = 7cm, b = 14cm (i) Area of Ring (ii) The perimeter of Ring
Find attached the diagram.
Step-by-step explanation:
a= smaller radius = 7cm
b= bigger radius = 14cm
i) Area of the ring = Area of larger circle - Area of smaller circle
Area of circle = Area of a ring = πr²
π =22/7
Area of larger circle = (22/7)(14)² = 22×28
Area of larger circle = 616cm²
Area of smaller circle = (22/7)(7)² = 22×7
Area of smaller circle = 154cm²
Area of the ring = 616 - 154 = 462cm²
ii) Perimeter of ring = Perimeter of larger circle + Perimeter of smaller circle
Perimeter of circle = 2πr
When r = 7cm and π = 22/7
Perimeter of smaller circle = 2×(22/7)×7 = 2×22
Perimeter of smaller circle = 44cm
When r = 14cm and π = 22/7
Perimeter of larger circle = 2×(22/7)×14 = 4×22
Perimeter of larger circle = 88cm
Perimeter of ring = 88+44 = 132cm

Brittany's kite is flying above a field at the end of 65 m of string. If the angle of elevation to the kite
measures 70°, how high is the kite above Brittany's head?
Answer:
61.1 m is the correct answer.
Step-by-step explanation:
Given that
Brittany's kite has a string length = 65 m
Angle of elevation of kite = [tex]70^\circ[/tex]
A right angled triangle can be constructed for the given situation.
Please refer to the attached figure.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The number of sheets of paper = 7 sheets
The number of pieces they were cut = 3 pieces
The new total number of sheets of paper = 13 sheets
So ,
The difference in sheets of paper =
new total number of sheets of paper - number of sheets of paper
The difference in sheets of paper = 13 - 7
= 6 sheets
Now , each paper is cut into 3 extra sheets
So , the number of papers cut =
The difference in sheets of paper / number of pieces they were cut
The number of papers cut = 6 / 3
= 2 sheets of paper

how do i find x and y?
Answer:
y=65
x=50
Step-by-step explanation:
exterior angle of a triamgle is equal to sum of two interior angles
so
2y=130(as it is isosceles triangle)
y=65
we know y+y+x=180(sum of all angles of triangle)and (vertically opposite angle)
therefore, x=50
Answer:
x=50°
y=65°
Step-by-step explanation:
I guess it would be better if there were alphabets representing each vertices otherwise it would difficult for you to understand
Let's take the point of intersection as O
Since It is a straight line(on both sides of O)=180°
Therefore x=180°-130°=50°
In the second triangle the angle at the top = 50° because x and that angle are vertically opposite to each other and therefore are equal
When the two sides of a triangle are equal, The base angles are always equal
Second triangle is 180°
The top angle is 50°
the base angles (which y and the angle below it)
is equal to 180°-50°=130°
Since base angles are equal and their sum is 130°, One base angle which is Y = 130°÷2=65°
