1. A line has a slope of 6 and includes the
points (-1, q) and (0, -7). What is the
value of q?
Answer:
q = - 13
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 6
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, q) and (x₂, y₂ ) = (0, - 7)
m = [tex]\frac{-7-q}{0+1}[/tex] = - 7 - q , then
- 7 - q = 6 ( add 7 to both sides )
- q = 13 ( multiply both sides by - 1 )
q = - 13
Answer:
q = -13?
Step-by-step explanation:
the equation is y = mx + c
m is the gradient
c is the y-intercept
where the line crosses the y axis
If 6 is the gradient then the equation is
y = 6x + c
Find c by using the coordinates given:
-7 = ( 6× 0) +c
-7 = 0 + c
c = -7
the equation is y = 6x -7
Substitute the other coordinates to find q:
y or q = (6 ×-1) - 7
q = -6 -7
q = -13
Sierra has plotted two vertices of a rectangle at (3,2) and (8,2). What is the length of the sides of the rectangle
Answer:
5units
Step-by-step explanation:
Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.
Using the formula
D = √(x2-x1)²+(y2-y1)²
D = √(2-2)²+(8-3)²
D = √0+5²
D = √25
D = 5
Hence the length of the side of the rectangle is 5units
Solve the equation on the interval [0,2pi)
The value of θ within the interval is 210 and 330 degrees
Given the equation;
[tex]2sin^2 \theta = 5sin \theta - 3[/tex]
Let P = sinθThe equation will become;
2P² = 5P - 3
2P² - 5P - 3 = 0
Factorize;
2P² - 6P + P- 3 = 0
2P(P-3) + 1(P -3) =0
2P + 1 = 0 and P - 3 = 0
p = -1/2 and 3
Since P = sinθ
sinθ = -1/2
θ = -30 degres
Since sine is negative in the second 3rd and 4th quadrant
θ = 180 + 30 = 210 degrees
θ2 = 360 - 30 = 330 degrees
Hence the value of θ within the interval is 210 and 330 degrees

Write the formula to evaluate the rate of VAT (V%) if
selling price with VAT is Rs. x and selling price without
VAT is Rs. y.
help.
Answer:
V% = (100(x - y)/x)%
Step-by-step explanation:
We are given;
Selling price with VAT = Rs. x
Selling price without VAT = Rs. y.
Thus; VAT = Rs. (x - y)
Rate of VAT(V%) = ((x - y)/x) × 100%
= (100(x - y)/x)%
Find the measure of angle H
Answer:
80
Step-by-step explanation:
All triangle angles add up to 180 so:

The line of best fit is:
y = 3.1x + 12.9
Option A is the correct answer.
We have,
The line of best fit can be expressed in the form of y = ax + b,
where a is the slope of the line and b is the y-intercept.
From the given LinReg results, we have:
a = 3.1
b = 12.9
Substituting a and b in the equation y = ax + b we get,
The line of best fit is:
y = 3.1x + 12.9
Thus,
The line of best fit is:
y = 3.1x + 12.9

Step-by-step explanation:
Hello.
The Distributive Property states that
a(b+c)=ab+ac
Where
a, b, and c can be either constants or variables
we distribute a by multiplying it times b and c, and simplify if necessary.
In this case, we should distribute 12:
12(a-5)
12 times a and 12 times (-5):
12a-60
And we're done!
