3x - 4y = 8
y = mx + b ; m is the slope ; b is the y-intercept
-4y = -3x + 8
y = -3x/-4 + 8/-4
<u>y = 3/4 x - 2</u>
Need to check if the given choices have the same slope.
3x + 4y = -8
4y = -3x - 8
y = -3/4 x - 8/4 = -3/4 x - 2
6x - 8y = 12
-8y = -6x + 12
y = -6/-8 x + 12/-8
y = 3/4 x - 1 1/2
9x - 12y = 24 This equation would cause a consistent-dependent system
-12y = -9x + 24
y = -9/-12 x + 24/-12
<u>y = 3/4 x - 2</u>
16x + 12y = -10
12y = -16x - 10
y = -16/12 x - 10/12
y = -1 1/3 x - 5/6
Answer:
5
Step-by-step explanation:
-5 + 5 = 0
4.
4^3 = 64
64X64 = 4096
4^6 = 4096
825
You just multiply 1000 × 0.825 = 825 students
First .... the limit of the given function is NOT EQUAL to 5 (it diverges so it has no limit). There is a typo. The 14 should be positive.
![\lim_{x \to\ 7} \bigg(\dfrac{x^2-9x+14}{x-7}\bigg)=5](https://tex.z-dn.net/?f=%5Clim_%7Bx%20%5Cto%5C%207%7D%20%5Cbigg%28%5Cdfrac%7Bx%5E2-9x%2B14%7D%7Bx-7%7D%5Cbigg%29%3D5)
The precise definition of a limit is:
