Answer:
x = -2
Step-by-step explanation:
5x + 7 = 2x + 1
subtract both sides by 2x
3x + 7 = 1
subtract both side by 7
3x = -6
divide both sides by 3
x = -2
Answer:
B. 51.1°
Step-by-step explanation:
You're gonna want to use sine on this one.
Sin(x) = 7/9
x = sin^-1(7/9)
x ≈ 51.1
First think of the form a^2 + 2c + c^2
c in the question is clearly 3.
So we need first to add 8 for both sides to get rid of -8 and then add 9 to complete the square.
So it will be (x^2+3)^2 = 17
So the choice number 3 is the answer.
Hope this helps!
Answer:
slope of the parallel line = 8
Step-by-step explanation:
Parallel lines have the same slope. To determine the equation of the other line, you need to transform the given linear equation into its slope-intercept form, y = mx + b:
-8x + y = 2
Add 8x to both sides to isolate y:
-8x + 8x + y = 8x + 2
y = 8x + 2 (this is the slope-intercept form where the slope (m) = 8, and the y-intercept (b) = 2).
Given that the slope of the first equation is 8, then we can assume that the slope of line parallel to -8x + y = 2 will also be 8.
Answer:
2 x 10^6
Step-by-step explanation:
10^6 = 1,000,000
2 x 1,000,000 = 2,000,000
10^5 = 100,000
9 x 100,000 = 900,000
2,000,000 > 900,000
