Answer:
x = 8
Step-by-step explanation:
Given
3(x - 1) - 2(x - 1) = 7 ← distribute both parenthesis on left side
3x - 3 - 2x + 2 = 7 , simplifying
x - 1 = 7 ( add 1 to both sides )
x = 8
F + s = 10
| f - s | = 18
-------
This means that:
f = 10 - s
And also that:
| f - s | = 18
(f-s)²=18²
f²- 2sf + s² = 324
But f=10-s
So...
(10-s)² - 2s(10-s) + s² = 324
(10-s)(10-s) - 20s + 2s² + s² = 324
100 - 20s + s² - 20s + 2s² + s² = 324
4s² - 40s + 100 = 324
4s² - 40s + 100 - 324 = 0
4s² - 40s - 224 = 0
1/4 * (4s² - 40s - 224) = 1/4 * 0
s² - 10s - 56 = 0
(s-14)(s+4)=0
So s can be either 14 or -4.
When s = 14, f = -4.
When s = -4, f = 14.
Answer:
the second one, is right
Step-by-step explanation:
when you see something like this, you can take the denominator of the fraction and put it outside the root, so it becomes a seventh root, and the number inside the root is then raised to the power of to numerator of the fraction. 3^4 = 81
sorry if i explained that bad :)
Answer:
The graph of the line that contains the point with a slope of 2/3.
Step-by-step explanation:
As the line contains the point (-3, 1) with a slop 2/3
Given the slop-intercept form of the line equation
y = mx+b
Here,
Substituting the values in the slop-intercept form of the line equation
switching sides
Now Substituting the value of in the slop-intercept form of the line equation
Hence, the line of the equation will be:
Therefore, the graph of the line that contains the point with a slope of 2/3.
