what is the y-intercept of (5,8) and (12,36)
Answers
Answer:
The y intercept is (0,-12)
Step-by-step explanation:
You use the slope formula and the slope-intercept form to find the slope m and then the y intercept b.
Answer:
(0, -12)
Step-by-step explanation:
In order to find the y-intercept of the equation y = mx + b ( where m is the slope and b is the y-intercept), we first have to find the slope. We can do this by using the two points given to us.
To find the slope:
The slope is equal to: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's plug (5,8) and (12,36) into the equation:
[tex]\frac{36 - 8}{12 - 5}[/tex]
Now let's solve for the slope:
36 -8 = 28
12 - 5 = 7
So we get: [tex]\frac{28}{7}[/tex]
Now that we've found the value of the slope, we can put it into the equation:
y = [tex]\frac{28}{7}[/tex]x + b
To find the value of b, we can input the values of one of the given points into the equation and solve for b. Let's use (5,8):
Input the values of x and y into the equation: 8 = [tex]\frac{28}{7}[/tex](5) + b
Multiple [tex]\frac{28}{7}[/tex] by 5: 8 = [tex]\frac{140}{7}[/tex] + b
Divide 140 by 7: 8 = 20 + b
Subtract 20 from both sides of the equation to isolate b:
8 - 20 = 20 - 20 + b
-12 = b
The y-intercept is (0, -12).
a rectangle has an area of 651m². One of the sides is 7m in length. Work out the perimeter of the rectangle
Answers
Answer:
200
Step-by-step explanation:
So first off, let's find the other side.
651 divided by 7 = 93
93 would be the other side measurement. There are two sides that measure 93 degrees, two sides that measure 7 degrees.
93 + 93 + 7 +7 = perimeter
Once we add up like terms, 200
Write the polynomial form given the leading coefficient
and the zeros of the function.
1. Leading coefficient: -1; roots: 1, 1+73, 1 - 3
someone help please
Answers
Answer:
For a polynomial of any degree, with roots x₁, x₂, ...., xₙ and a leading coefficient A, we can write it as:
p(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)
In this case, we have:
Leading coefficient = -1
Roots : 1, 1 + 73, 1 - 3
Then the polynomial will be:
p(x) = -1*(x - 1)*(x - (1 + 73))*(x - (1 - 3))
= -1*(x - 1)*(x - 74)*(x + 2)
Now, if the roots are:
1, 1 + 73*i, 1 - 3*i
then:
p(x) = -1*(x - 1)*(x - 1 - 73*i)*(x - 1 + 3*i)

Answers
The correct way of counting the total number of passenger seats in this bus is: option C: 5 × 12 + 6.
What is an expression?An expression refers to a mathematical equation which is used to show the relationship that exist between two or more numerical quantities.
How to calculate the total number of passenger seats?In order to determine the total number of passenger seats, we would develop an expression that multiplies the rows by the columns and then add the remaining seats as follows:
Total number = (5 × 12) + 6
Total number = 60 + 6
Total number = 66 seats.

The length of each of the two congruent sides of an isosceles triangle is 3x - 1. The length of the third side is 2x + 1. The perimeter is 55 feet. Which equation does NOT represent the perimeter?
8x - 1 = 55
6x - 2 + 2x + 1 = 55
2 (3x - 1 + 2x + 1) = 55
2 (3x - 1) + (2x + 1) = 55
Answers
Explanation:
This equation does not represent the perimeter.
To write the equation:
2(3x - 1) + (2x + 1) = 55
6x - 2 + 2x + 1 = 55
8x - 1 = 55
Thus, 3 of the choice represent but the the third choice didn’t appear in the equation.
a waterslide has an angle of elevation of 20 degrees whats is the rise for a run of 2.6 m?
Answers
Answer:
Therefore, the rise will be 0.95 m
Step-by-step explanation:
As the waterslide has an angle of elevation of 20 degrees.
Ф = 20°
And we have to determine the rise for a run of 2.6 m.
All we need is to use the trigonometric ratio of tan Ф
Because
tan Ф = rise/runAs
run = 2.6 m
Ф = 20°
so
tan Ф = rise/run
tan (20) = rise/run
rise = tan (20) × 2.6
rise = 0.95 m
Therefore, the rise will be 0.95 m
