Determine whether the graphs of the given equations are parallel, perpendicular, or neither.
Y= -2x+3
2x+y=7
A. Parallel
B. Perpendicular
C. Neither
Answer:
A
Step-by-step explanation:
Because the have the same slope.
The second equation solving for y is:
Y= -2x+7.
Both equations have the same slope of -2
Answer:
Parallel
Step-by-step explanation:
If lines have the same slope, then they are parallel. If lines have slopes that are opposite reciprocals of each other, then they are perpendicular. If neither one of those statements are true, then the answer is neither.
1) First, find the slope of the first equation. [tex]y = -2x + 3[/tex] is already in [tex]y = mx + b[/tex] format, or slope-intercept form. The [tex]m[/tex], or the coefficient of the x term, represents the slope. Thus, by looking at the equation, -2 is the slope of [tex]y = -2x + 3[/tex].
2) Second, find the slope of the second equation. [tex]2x + y = 7[/tex] is in standard format, but we can change it to slope-intercept format by isolating the y like so (just subtract both sides by 2x):
[tex]2x + y = 7 \\y = -2x + 7[/tex]
Now that it is in slope-intercept form, we can look at the coefficient of the x term, or [tex]m[/tex], to find the slope. That number is -2, thus the slope of [tex]2x + y = 7[/tex] is -2.
3) We found out that the slopes of both equations are -2. Thus, since they share the same slope, the lines are parallel.
Calculate x
I ll mark you as the brainliest
Answer
x = 18 cm
Step-by-step explanation:
Here, we want to calculate the value of x
let half of x = b
so b is the base of each right-triangle
As we can see, the triangle is isosceles
we can calculate the length of the base of one of the smaller right angled triangle and multiply by 2 to get the full x length
According to Pythagoras’ , the square of the hypotenuse equals the sum of the squares of the two other sides
15^2 = 12^2 + b^2
225 = 144 + b^2
b^2 = 225-144
b^2 = 81
b = √81
b = 9
but x = 2b
x = 2(9)
x = 18 cm

In the city where sonya lives, it rains and average of 8.05 centimeters each month last year.About how many centimeters of rain fell in all last year? Show your work.
The total centimeters of rainfall in the city for the past year where Sonia lives is given by the equation A = 96.6 cm
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 ,
Let the total centimeters of rainfall for the past year be A
Now , the equation will be
The centimeters of rainfall every month in the city = 8.05 cm
The total number of months in a year = 12 months
So ,
The total centimeters of rainfall in the city for the past year A = centimeters of rainfall every month in the city x total number of months in a year
Substituting the values in the equation , we get
The total centimeters of rainfall in the city for the past year A = 8.05 x 12
On simplifying the equation , we get
The total centimeters of rainfall in the city for the past year A = 96.6 cm
Therefore , the value of A is 96.6 cm
Hence , the total rainfall is 96.6 cm

Use the Pythagorean theorem to solve each problem. Show Calculations.
Answer:
1) 25 miles
2) 20 m
Step-by-step explanation:
Number 1 is going to be
[tex]a^{2} + b^{2} = c^{2}[/tex] because it's a right triangle
So
[tex]24^{2}[/tex] + [tex]7^{2}[/tex] = [tex]c^{2}[/tex]
625 = [tex]c^{2}[/tex]
c = 25 mile
Number 2 uses the same process, but changing to using C instead of A
a^2 = c^2 - b^2
a^2 = 625 - 225
a = \sqrt(400)
a = 20m

The radius of the front wheel of Monica's bicycle is 1 foot. About how far has Monica traveled after the wheel has made 100 revolutions? (use 3.14 for pi)
Answer:
Distance travel by Monica = 628 ft
Step-by-step explanation:
Given:
Radius of whee l = 1 ft
Number of revolution = 100
Find:
Distance travel by Monica
Computation:
Distance travel by Monica = 100[Circumference of wheel]
Distance travel by Monica = 100[2πr]
Distance travel by Monica = 100[2(3.14)(1)]
Distance travel by Monica = 100[6.28]
Distance travel by Monica = 628 ft
