- a positive slope will be an increasing line (an uphill line)
- a negotiate slope will be a decreasing line (a downhill line)
- a zero slope will be a flat line (no incline or decline)
- an undefined slope fits with a line that doesn’t go left-to-right. It’ll be a vertical line.
For line 1 slope is negative, for line 2 slope is undefined, for line 3 slope is positive and for line 4 slope is zero.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
The slope of a line is a measure of its steepness and direction. To determine the sign of the slope, we need to look at the direction of the line:
If the line is slanting upwards from left to right, the slope is positive.If the line is slanting downwards from left to right, the slope is negative.If the line is vertical, the slope is undefined (since the denominator of the slope formula, which is the difference in x-coordinates, is zero).If the line is horizontal, the slope is zero (since the numerator of the slope formula, which is the difference in y-coordinates, is zero).Therefore, Lines 1, 2, and 4 have negative slopes, undefinable slopes for lines 2 and 3, and positive slopes for lines 3 and zero for lines 4.

6 + 4w = 2w − 6
Solve for W
Answers
When we subtract 2w from both sides we get 2w on the left and 0 on the right. The equation becomes 6+2w=-6. Then we subtract both sides by 6 making it 2w=-12 and when we divide each side by 2 we get w=-6
Answer:
W=-6
Step-by-step explanation:
6+4w=2w-6
Collect Terms
4w-2w=-6-6
2w=-12
now divide both sides by 2
2w/2=-12/2
w=-6

P = 235.619/1256.637 ≈ 0.187 or 18.7%Answer:
4
We know that
Area of rectangle = lb
Area = 10(20)
Area = 200 m²
Shaded region = πr²
=> 2 × 22/7 × (10/2)²
=> 2 × 22/7 × 10/4
=> 157 m²
Probability = 157/200 = 78.5%
5.
Area of the biggest circle = πr²
= 22/7 × (20)²
= 1256.6
Area of shaded region
π(10² - 5²)
π(100 - 25)
3.14(75)
235.6
Probability = 235.6/1256.6 = 18.7%
8a=4(a-9)
Show work I need help
Answers
Answer:
a = -9
Step-by-step explanation:
8a=4(a-9)
Divide each side by 4
8a/4=4(a-9)/4
2a = a-9
Subtract a from each side
2a-a = a-9-a
a = -9
Answer:
-9
Step-by-step explanation:
8a = 4(a-9)
Use the distributive property (Multiply 4 times a, and 4 times -9)
8a = 4a - 36
Bring the 4a to the other side
8a - 4a = -36
Add like terms
4a = -36
Divide both sides by 4 to get a by itself
a = -9

Answers
Answer:
(x - 8)(x + 4)
(x + 4)(x - 8)
Step-by-step explanation:
(x - 16)(x + 2)
= x2 + 2x - 16x - 32
= x2 - 14x - 32
(x + 2)(x - 16)
= x2 - 16x + 2x - 32
= x2 - 14x - 32
(x - 8)(x + 4)
x - 8)(x + 4) = x2 + 4x - 8x - 32
x - 8)(x + 4) = x2 + 4x - 8x - 32 = x2 - 4x - 32
( 30 + x)(x - 4)
= 30x - 120 + x2 - 4x
= x2 + 26x - 120
(x + 4)(x - 8)
(x + 4)(x - 8) = x2 - 8x + 4x - 32
(x + 4)(x - 8) = x2 - 8x + 4x - 32 = x2 - 4x - 32
(x - 4)(x + 8)
= x2 + 8x - 4x - 32

Answers
Answer:
Step-by-step explanation:
ab² + 2a²b + a³ = a(b² + 2ab + a²)
Here variable 'a' is common in all the terms. HCF = a
2) 2ab² = 2 * a * b *b
4a²b = 2 * 2 *a * a * b
6a³ = 2 * 3 * a * a * a
HCF = 2a
2ab² - 4a²b - 6a³ = 2a(b² - 2ab - 3a²)

Express the area of the emotive rectangle?
Formula used:
Area of rectangle = Length × Breadth.
Solutions:
Length = 5 and Breadth = x² + 2
We know that:
Area of rectangle = Length × Breadth.
Substitution the value of Length × Breadth.
= 5 × (x² + 2)
= 5x² + 10
Hence, the area of the emotive rectangle is 5x² + 10

The line passing through points (5,) and (2,−3) is parallel to a line with a slope of 4/3. What is the value of y?
Answers
Answer:
Step-by-step explanation:
Parallel lines have same slope
Slope = [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]\dfrac{-3-y}{2-5}=\dfrac{4}{3}\\\\\\\dfrac{-3-y}{-3}=\dfrac{4}{3}\\\\\\-3-y=\dfrac{4}{3}*(-3)\\\\\\[/tex]
-3-y = 4*(-1)
-3 - y = -4
- y = - 4 + 3
-y = -1
Divide both sides by (-1)
y = 1
