(-7,10) perpendicular to 2x - 3y= -3 using slope-intercept form
y = -3/2x - 20.5 is the line crossing through (-7,10) perpendicular to 2x - 3y= -3
In an equation, parallel lines have the opposite reciprocal slope. In other words, if a line's slope is a positive fraction, its reciprocal slope is negative.
Here given that 2x - 3y= -3
can also be written as
y = 2/3x + 1
Here 2/3 is the slope and 1 is the y-intercept
To find a parallel line to the following equation, use the opposite reciprocal slope and point, then solve using the point-slope formula.
y - y₁ = m(x - x₁)
We have, m = -3/2, x₁ = -7 and y₁ = 10
y - 10 = -3/2(x - (-7))
y - 10 = -3/2(x + 7)
y - 10 = -3/2x - 21/2
y = -3/2x - 21/2 + 10

The altitude a (in feet) of a plain t minutes after liftoff is given by a= 3400t + 600. How many minutes after liftoff is the plane at an altitude of 21,000 feet?
The number of minutes after liftoff of the plane at an altitude of 21,000 feet is 6 minutes
What is a function?A function can be defined as an expression or law that shows the relationship between a dependent and independent variable.
Given the function;
a= 3400 t + 600
Where;
a is the altitude in feett is the time in minutesIf the altitude is 21000 feet, let's determine the time
Substitute the value into the function
21000 = 3400t + 600
collect like terms
21000 - 600 = 3400t
20400 = 3400t
Make 't' the subject
t = 20400/ 3400
t = 6 minutes

How can u determine whether a relation represented as an equation is a function
It can be determined that a relation represented as an equation is a function if and only if for each value on x-axis, there is a corresponding value on Y-axis.
which also signifies that for each value of x , there is a value of y which exists and is real.
A function is a mapping from one set to another such that nothing in the first set is mapped to more than one thing in the second set.
Or in simple words if there is no corresponding value of y for any x, then that is not a function.
For example,
[tex]x^{2} +y^{2}[/tex]=1
when the value of x is 0 , then value of y is 1 or -1, Thus, it will not be a function.

A leather recliner with a regular price of $795.00 is on sale for 15% off. What is the sale price of the recliner?
Answer:
$675.75
Step-by-step explanation:
To find the sale price of the recliner, we can multiply 15% by the regular price.
15% = 0.15
(0.15)(795.00) = $119.25
This gives us the amount that the sale takes off from the regular price. We can subtract that from the regular price to find the sale price.
795.00 - 119.25 = $675.75
A bonus shortcut way to get our answer would be to subtract 15% from 100%.
100% = 1.00
1.00 - 0.15 = 0.85
This tells us that the sale price is 85% of the regular price. Using this information, we can multiply 85% by the regular price to also get our sale price.
85% = 0.85
(0.85)(795.00) = $675.75

An equation that represents the cost of one pound of bananas in terms of the cost of one pound of apples is,
⇒ b = 2a + 30
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Cost of one pound of grapes = g
Cost of one pound of apples = a
Cost of one pound of banana = b
Since, The cost of one pound of grapes is 15 cents more than one pound of apples.
It can be written as;
g = a + 15 .... (i)
And, The cost of one pound of bananas is twice as much as one pound of grapes.
It can be written as;
b = 2g ..... (ii)
To find an equation that represents the cost of one pound of bananas in terms of the cost of one pound of apples as,
Put the value of g from (i) in (ii) we get,
b = 2 ( a + 15 )
b = 2a + 30
Hence, An equation that represents the cost of one pound of bananas in terms of the cost of one pound of apples is,

An angle measures 84.2° less than the measure of its supplementary angle. What is the measure of each angle?
The measure of the supplementary angles are 48° and 132°.
Let the measure angle be x.
Its supplementary angle will be x + 84
We know that the sum of supplementary angles is 180°.
So, we get the equation as:
x + x + 84 = 180
Combining the like terms, we get that:
2 x + 84 = 180
Subtract 84 from both sides, we get that:
2 x = 180 - 84
2 x = 96
Divide both sides by 2, we get that:
x = 96 / 2
x = 48°
x + 84 = 48+ 84 = 132°
Therefore, we get that, the measure of the supplementary angles are 48° and 132°.

a rectangle has perimeter 24 m. express the area a of the rectangle as a function of the length, l, of one of its sides.
The Expression for the Area a of the rectangle as a function of length L is given by A(L) = 12L - L^2 .
Let,
length, L, and the width, W, are components that help determine the area, A, and the perimeter, P of the rectangle. These are given by the following equations
A=LW
P=2L+2W
Given,
Perimeter of the Rectangle = 24m.
We are asked to express the perimeter of the rectangle as a function of the length, L, of one of its sides.
We will first set up the equation of the Perimeter of the rectangle. We can let the width of the rectangle be W.
P = 2L+2W
24 = 2L+2W
12 = L+W
W = 12-L
Since we want to express the Area as a function of L, we have to find the value of W in terms of L. This is so we can eliminate the width in the equation for the Area. The Area as a function of L is as follows.
A(L, W) = LW
A(L) = L(12-L)
A(L) = 12L-L^2
Therefore, the Area as a function of L is given by A(L) = 12L-L^2.

At the end of 1994 Walters Was half as old as his grandmother. The sum of the years in which they were born in 3838. How old will Walter be at the end of 1999?
The age of Walter at the end of year 1999 will be equal to 55 years.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
Let's assume respective age of Walter and Walter's grandmother is x and y years respectively.
In 1994 , age of Walter was :
x = y / 2
or y = 2x
It is also given that the sum of years they were born is 3838.
The year Walter was born = (1994 - x)
The year Walter's grandmother was born :
= (1994 - y)
= 1994 - 2x (∵ y = 2x)
So , we can write an equation to find out Walter's age which is :
1994 - x + 1994 - 2x = 3838
3988 - 3x = 3838
3x = 3988 - 3838
x = 150 / 3
x = 50 years
or the age of Walter in 1994 is 50 years.
At end of 1999 Walter's age will be:
= 50 + 5.
= 55 years
Therefore , the age of Walter at the end of year 1999 will be equal to 55 years.
