Answer:
slope = -4
Step-by-step explanation:
3y = 9 - 12x
Rearrange the right-hand side:
3y = - 12x + 9
Next, Divide both sides by 3 to isolate y:
[tex]\frac{3y}{3} = \frac{-12x + 9}{3}[/tex]
y = -4x +3 this is the slope-intercept form where the slope, m = -4, and the y-intercept, b = 3.
Therefore, the slope = -4.

12. Write an equivlent expression for -8b - 4y + 12 with a coefficient that is negative.
Answer: It's possible to change a negative sign to a minus sign because for example when you have two integers 5 and -3, 5-3 is the exact same as 5+(-3). So basically, adding a negative number and a positive number is the same as subtracting the larger absolute value from the number with the lower absolute value
Step-by-step explanation:
Answer:
We could write -2(4b+2y-6), since it is an expression that is equal to -8b - 4y + 12 and has a negative coefficient.
PLEASE! An item costs 410 before tax, and the sales tax is 32.80.
Find the sales tax rate. Write your answer as a percentage.
Divide the amount of the tax by the cost of the item:
32.80 / 410 = 0.08
Multiply by 100:
0.08 x 100 = 8%
Answer: 8%

Answer:A ps=qr
Step-by-step explanation:opposite sides of a rectangle have equal length
MARK ME BRANLIEST
Answer:
SR = RQ
Step-by-step explanation:
In a rectangle, opposite sides are congruent, which means that the length of side SR is equal to the length of side RQ. Therefore, the statement SR = RQ is true for a rectangle.

A garden is 8 feet by 12 feet and Lewis wants to increase the area by 25%. what could be the new dimensions of the garden?
Answer:
10ft by 12ft
Step-by-step explanation:
Step 1 : Find the area of the garden.
Area formula = length * width
Area = 8 * 12
Area = 96
Step 2 : Find 25% of 96.
96 divided by 4 = 24
Step 3 : Add that 25% (24) onto 96.
24 + 96 = 120
We now know that the new area of the garden is 120 [tex]feet^{2}[/tex].
The new dimensions of the garden could be 10 times 12, since that equals 120. Therefore, the answer is 10ft by 12ft.

Points A and B have coordinates (8, 3) and (p, q) respectively. The equation of the perpendicular
bisector of AB is y = -2x +4.
Find the values of p and q.
Answer:
p = -4, q = -3
Step-by-step explanation:
y = -2x +4 ... (1) perpendicular bisector of AB, slope = -2
slope of AB = 1/2
Line AB pass (8,3): (y-3) / (x-8) = 1/2
AB equation: y-3 = 1/2(x-8) y = 1/2x - 1 ... (2)
(2)-(1): 5/2 x = 5 x = 2
y = 0 (2,0) intercept of bisector and AB, it is midpoint of A (8,3) and (p,q)
(8+p)/2 = 2
p = -4
(3+q)/2 = 0
q = -3
The values of p and q from the perpendicular bisector are;
p = -4 and q = -3
We are given coordinates of A and B as;
A(8, 3) and B(p, q)
Bisector of AB is y = -2x + 4
Thus, from y = mx + c, Slope of the bisector is -2.
Since the bisector is perpendicular to AB, then slope of AB = -(1/-2) = 1/2
Thus, slope of the line from point A to the point of the bisector on AB is;
(y - 3)/(x - 8) = 1/2
y - 3 = ¹/₂(x - 8)
y - 3 = ¹/₂x - 4
y = ¹/₂x - 1
Putting ¹/₂x - 1 for y in the bisector equation gives;
¹/₂x - 1 = -2x + 4
2x + ¹/₂x = 4 + 1
2.5x = 5
x = 5/2.5
x = 2
Thus;
y = -2(2) + 4
y = 0
Thus, the coordinate of the midpoint of AB is (2, 0)
Now, this means that;
(8 + p)/2 = 2
8 + p = 4
p = 4 - 8
p = 4
Also; (3 + q)/2 = 0
3 + q = 0
q = -3

A line has a slope of -4 and includes the points (-3, p) and (-4,0). What is the value of p?
Answer:
p = - 4
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 4
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, p ) and (x₂, y₂ ) = (- 4, 0 )
m = [tex]\frac{0-p}{-4-(-3)}[/tex] = [tex]\frac{-p}{-4+3}[/tex] = [tex]\frac{-p}{-1}[/tex] = p = - 4

Find the x and y-intercepts of :
3y-6x=18
Answer:
x- intercept = -3 units
y- intercept = 6 units
Answer: y intercept=6 x intercept=-3
Step-by-step explanation:
The y-intercept is when x is 0 so we plug in the value of x with 0 and solve for y.
Similarly, the x-intercept is when y is 0 so we plug in the value of y with 0 and solver for x.

Identify the vertex of the equation y=x^2−6x+2. Show all work for full credit.
Answer:
(3, -7)
Step-by-step explanation:
y = x² - 6x + 2
a = 1, b = -6
[tex]x = - \frac{ - 6}{2 \times 1} [/tex]
x = 3
y = x² - 6x + 2; x = 3
y = -7
= (3, -7)
put the following equation of a line into a slope-intercept form, simplifying all fractions.
3y-3x=21
To find the slope-intercept form (y=mx+c), we have to make 'y' the subject of the equation:
3y - 3x = 21 [add 3x to both sides]
3y = 3x + 21 [divide all terms by 3]
y = x + 7
∴ 3y - 3x = 21 in slope-intercept form is y = x + 7.
