4(5x - 6) - 4(2x + 1)
20x - 24 - 8x - 4
12x - 28
Answer:
x = 15
Step-by-step explanation:
Assuming 3x and x-60 are in degrees, you can use:
cos(a) = sin(a+90)
To rewrite the equation as:
sin(3x) = sin(x-60+90)
sin(3x) = sin(x+30)
3x = x+30
2x = 30
x = 15
But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
7x-2=-23 add 2 to both sides to get 7x by itself
7x=-23+2 now add the right side
7x=-21 now divide both sides by 7
x=-21/7
x=-3
Answer:
the slope increases
Step-by-step explanation:
Write a new equation using the new y-intercept and same slope as the original equation. Analysis: What effect does changing the y-intercept of an equation have on the graph? Increasing a y-intercepts moves the graph up. Decreasing a y-intercept moves the graph down.
1 cup is 8 fluid ounces
so 60 cups is bigger.
