5(x + 1)....distribute the 5 thru the parenthesis...that means multiply the 5 by everything in the parenthesis.
5(x + 1) = 5 * x + 5 * 1 = 5x + 5
Answer:
Step-by-step explanation:
This problem tests your understanding of order of operations rules.
Here you must do any work inside parentheses first, followed by multiplication, followed by subtraction:
5(13) - 3(2 -1) would be 65 -3(1), or 62.
If you actually meant 5(1 - 3) - 3(2 - 1), then you'd have
5(-2) - 3(1) = -10 - 3 = -13
Please compare the problem you've shared with the original problem, to ensure that these match.
Answer:
x1 = 2, y1 = 0
x2 = 2, y2 = 6
Step-by-step explanation:
Each pair of coordinates is (x, y). The first pair is (x1, y1). The second pair is (x2, y2). This means you have ...
x1 = 2, y1 = 0
x2 = 2, y2 = 6
_____
<em>Additional comment</em>
The slope of the line through these points is ...
m = (y2 -y1)/(x2 -x1) = (6 -0)/(2 -2) = 6/0 = undefined
The line through these points is a vertical line with equation x = 2.
Answer: 0.63
Step-by-step explanation:
1. Move the decimal point two places to the right giving you 0.63
Answer:
Step-by-step explanation:
Triangle DEF is a right angle triangle.
From the given right angle triangle,
DE represents the hypotenuse of the right angle triangle.
With ∠E as the reference angle,
EF represents the adjacent side of the right angle triangle.
DF represents the opposite side of the right angle triangle.
To determine EF, we would apply
trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 49 = EF/8
EF = 8Cos49 = 8 × 0.6561
EF = 5.2488
Rounding to the nearest tenth, it becomes 5.2
