Answer:
We know that negative times anything means that it will change the sign. Ideally, the second negative should change the sign of our original number (which is also negative). So, our original negative sign is changed into a positive sign when a negative is multiplied to it.

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.

a) What is the x-intercept?
b) What is the y-intercept?
c) What is the slope?
Please help ASAP
Answer:
Step-by-step explanation:
The x-intercept is where y is 0.
The y-intercept is where x is 0.
The x-intercept would be (-4, 0) and the y-intercept (0, 2)
Using the slope formula, (y2-y1/x2-x1), we can find the slope which is 1/2.

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 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.

Directions: Solve for x, then find each angle measure.
The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
It is known that the sum of all three angles inside a triangle will be 180°.
Therefore, ∠E + ∠F + ∠D = 180°.
Given that, ∠E = 9x + 3,∠F = 11x -21 and ∠D = 5x - 2
So, 9x + 3 + 11x - 21 + 5x - 2 = 180
25x - 20 =180
25x = 200
x = 8
So,
∠E = 9(8) + 3 = 75°
∠F = 11(8) - 21 = 67°
∠D = 5(8) -2 = 38°
Hence "The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°".

Answer:
x = 10
Step-by-step explanation:
1. First, we should recognize that 6x and 5x + 10 are corresponding angles, meaning they occupy the same relative position. They're also congruent.
This means that 6x = 5x + 102. (Solving)
Step 1: Subtract 5x from both sides.
[tex]6x - 5x = 5x + 10 - 5x[/tex] [tex]x = 10[/tex]Step 2: Check if solution is correct.
[tex]6(10)=5(10)+10[/tex] [tex]60 = 50 + 10[/tex] [tex]60 = 60[/tex]Therefore, x = 10.

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.
