Answer:
x = 2
AB = 14
Step-by-step explanation:
2x(10) = 8(x+3)
20x = 8x + 24
subtract 8x from both sides
12x = 24
x = 2
Check:
4(10) = 8(5)
40 = 40
Correct
2x = 2 x 2 = 4
4 + 10 = 14

Answer: A
Step-by-step explanation:
In this equation, the largest exponent is odd, so the two ends are going in different directions. Since the leading coefficient is positive, the left side is going down, while the right side is going up.
As y approaches negative infinity (goes down), x approaches negative infinity (goes left).
Simplified: as the y value decreases, the x value decreases.
As y approaches infinity (goes up), x approaches infinity (goes right).
Simplified: as the y value increases, the x value increases.
Answer:
y = 1/4 x - 12.5
Step-by-step explanation:
8x + 2y = -8 (rewrite in y = mx + b form)
2y = -8x -8 (divide both sides by 2)
y = -4x -2 for first line
Perpendicular line L has "opposite/inverse" slope
y = -4x + b becomes y = 1/4 x + b
What's b (the y-intercept)?
Plug the point (2, -12) into the equation y = 1/4 x + b to solve for b
-12 = 1/4 (2) + b
-12 = 1/2 + b (subtract 1/2 from both sides)
-12.5 =b (rewrite equation)
y = 1/4 x - 12.5
Answer:
The sum of coefficients = 9
Step-by-step explanation:
The given expression is,
3x⁴ + 5x² + x
There are three terms in the given expression. All the terms contains variable x.
<u>To find the coefficients of each terms</u>
<u>term</u> <u>coefficients</u>
3x⁴ 3
5x² 5
x 1
<u>To find the sum of coefficients</u>
sum = 3 + 5 + 1 = 9
Therefore the sum of coefficients = 9
