Use the point and the slope to graph each line. Write the equation of the line
Answers
Answer:
y = x in the slope intercept form
y - 2 = 1(x -2) in the point-slope form of a line
Step-by-step explanation:
Perpendicular slopes are opposite reciprocals of each other. So the perpendicular slope would be 1.
We could write this in the point slope form of a line and the answer would be:
y - 2 = 1(x -2) This would be the point slope form of a line.
If you want your answer in the slope intercept form
y -2 = 1(x-2)
y - 2 = x - 2 Add two to both sides
y = x
WHAT DO WE KNOW ABOUT PERPENDICULAR LINES ?
IS THAT WHEN THEIR GRADIENTS ARE MULTIPLIED THEY GIVE A PRODUCT OF -1.
TO FIND THE GRADIENT OF THE LINE PERPENDICULAR TO THE LINE WITH SLOPE/GRADIENT -1 WE CAN SAY
[tex]m1 \times m2 = - 1 \\ - 1 \times m2 = - 1 \\ m2 = 1[/tex]
THIS MEANS THAT THE GRADIENT OF THE NEW LINE IS 1
the general equation of the straight line is y=mx+c
[tex] - 2 = 1(2) + c \\ - 2 = 2 + c \\ c = - 2 - 2 \\ c = - 4[/tex]
This means that
[tex]y = 1x - 4 \\ simply \\ y = x - 4[/tex]

What are fractions?An element of a whole is a fraction. The number is represented as a quotient in mathematics, where the numerator and denominator are divided.p/q is a common way to represent fractions. They are divided into three categories: proper fractions, improper fractions, and mixed fractions depending on the numerator and the denominator.Given:
Amount of flour required for one batch of cookies = [tex]1\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]
Amount of flour needed for 2/3 of a batch of cookies = [tex]\frac{2}{3} * \frac{7}{4}[/tex] = [tex]\frac{7}{6}[/tex] = [tex]1\frac{1}{6}[/tex]

We have to calculate the number of seconds for the flare to return to the sea.
We have an initial vertical speed of 448 ft/s.

a right rectangular prism is packed with cubes of side length 1/6 inch. if the prism is packed with 12 cubes along the length, 3 cubes along the width, and 2 cubes along the height, what is the volume of the prism?
Answers
The volume of the right rectangular prism= 1/3 cubic inches
In this question, we have been given a right rectangular prism is packed with cubes of side length 1/6 inch.
We need to find the volume of the rectangular prism if the prism is packed with 12 cubes along the length, 3 cubes along the width, and 2 cubes along the height.
The length of the rectangular prism would be,
l = 12 × 1/6
l = 2 inches
The width of the rectangular prism would be,
w = 3 × 1/6
w = 1/2 inches
The height of the rectangular prism would be,
h = 2 × 1/6
h = 1/3 inches
so, the volume of the rectangular prism would be,
V = l × w × h
V = 2 × 1/2 × 1/3
V = 1/3 cubic inches
Therefore, the volume of the rectangular prism = 1/3 cubic inches

If a scale of a map is 1:10000 what will be the length on this map of a road which is 5 km long?
Answers
Step-by-step explanation:
1:10000
means we are using the same metric on the map and in reality.
just 1 unit in the map corresponds to 10000 units in reality.
so, e.g. 1 cm on the map = 10000 cm in reality.
1 m = 100 cm
so, 10000 cm = 100 m.
therefore, 1 cm on the map = 100 m in reality.
but we need 5 km = 5000 m.
that is 50 times 100 m in reality or 1 cm on the map.
so, the length on the map is 50 cm.

The measures of the angles of a triangle are shown in the figure below. Find the

(2x+7)°
Answers
The smallest angle of the right triangle is 27 degrees.
How to find the angle of a right triangle?A right triangle is a triangle that has one of its angles as 90 degrees.
The sum of angles in a triangle is 180 degrees.
Therefore, the measure of the smallest angle in the triangle can be found as follows:
90 + 6x + 3 + 2x + 7 = 180
combine like terms
90 + 6x + 3 + 2x + 7 = 180
6x + 2x + 90 + 3 + 7 = 180
8x + 90 + 10 = 180
8x + 100 = 180
subtract 100 from both sides of the equation
8x + 100 = 180
8x + 100 - 100 = 180 - 100
8x = 80
divide both sides by 8
8x / 8 = 80 / 8
x = 10
angle 1 = 6(10) + 3 = 60 + 3 = 63°
angle 2 = 2(10) + 7 = 20 + 7 = 27°
Therefore,
smallest angle of the triangle = 27 degrees.

How to find his salary prior?An employee's pay is the amount of money that they are given each month by their employer, particularly if they work in an occupation like education, law, or medicine.
For instance, the lawyer received a big salary.
Given,
Ron Fortini received a 5.20% merit increase
2.75% cost-of-living increase
His new weekly salary is $968.80.
Solution:
Let's take his initial salary as x.
The total increase in Ron's salary = 5.20%+2.75% = 7.95%
i.e.,
107.95% * x = $968.80
107.95/100*x = 968.80
x = 968.80 * 100/107.95
x = 897.45
His weekly salary prior to the increases is $897.45.
