① 15² = 4² + 2(32) x
225 = 16 + 64x
-64x = 16 - 225
-64x = -209
x = 209/64
② 105 = 45 + 5x
-5x = 45 - 105
-5x = -60
x = 60/5
x = 12
Answer:
5760
Step-by-step explanation:
(2 * 10)^6 * 0.00009
First solve inside the parentheses
20^6 * 0.00009
Then solve powers
64'000'000 * 0.00009
Solve multiplications
5760
This answer might not be the one that is asked for, as the writing is kind of vague, but if you turn this inn with explanation you will not get it wrong
Answer:
Graph C
Step-by-step explanation:
Hi there!
The given linear equations are organized in slope-intercept form:
where <em>m</em> is the slope of the line and <em>b</em> is the y-intercept, or the value of y when the line crosses the y-axis.
y = 2x + 4
Here, the <em>b</em> value is 4. Therefore, the y-intercept of this line is 4.
y = -3x - 2
Here, the <em>b</em> value is -2. Therefore, the y-intercept of this line is -2.
To identify the graph that models these equations, we just have to look for the graph where the lines cross the y-axis at 4 and -2.
The only graph that does this is graph C.
I hope this helps!
Answer:
n=2
Step-by-step explanation:
14=6n+6-2n
Combine like terms
14 = 4n+6
Subtract 6 from each side
14 -6 = 4n+6-6
8 = 4n
Divide by 4
8/4 = 4n/4
2 =n
