Answer:
Zero! NO SOLUTION
Step-by-step explanation:
Try solving it.
-46x - 23 = 46x + 23
Divide out the 23. :-)
-2x - 1 = 2x + 1
(-1) * (2x + 1) = 2x + 1
(-1) = 1
False, NO SOLUTION
Answer:
Therefore, Δx=5/n, when have n intervals.
Step-by-step explanation:
From exercise we have interval [0,5]. So the length of the given interval is 5-0=5. Since all intervals [x0,x1],[x1,x2],…,[xn−1,xn] are equal in width.
We know that their width is Δx. We conclude that width of each subinterval Δx in terms of the number of subintervals n is equal 5/n.
Therefore, Δx=5/n, when have n intervals.
Since there is an expression in the square root, it must be non-negative. So:
![f(x)=\sqrt{12-3x}\\\\ \Longrightarrow 12-3x\geq0\\\\ 3x\leq12\\\\ x\leq\dfrac{12}{3}\\\\ x\leq4](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%7B12-3x%7D%5C%5C%5C%5C%20%5CLongrightarrow%2012-3x%5Cgeq0%5C%5C%5C%5C%203x%5Cleq12%5C%5C%5C%5C%20x%5Cleq%5Cdfrac%7B12%7D%7B3%7D%5C%5C%5C%5C%20x%5Cleq4)
Then, the interval is:
Answer:
The equation would be y = -1/2x + 4
Step-by-step explanation:
The formula for slope-intercept form is y = mx + b, where m is the slope and b is the intercept. So, you simply add those numbers in where those letter are.
