Answer:
x = 0
y = 3
Explanation:
There are multiple ways to solve systems of equations. For this particular example, you can simply set them equal to each other because they are both equal to y and y = y, so therefore the equations equal each other.
so,
2x + 3 = -3x + 3
then solve for x!
add 3x to both sides: 5x + 3 = 3
subtract 3 from both sides: 5x = 0
divide by 5: x = 0
then to find y, plug the 0 back into either equation.
y = 2(0) + 3
y = 3
so, x = 0 and y = 3
i hope this helps!! :)
Here's the "compound amount" formula:
A = P (1 + r/[n]) ^ (nt).
Mama52's comment, above, would be true EXCEPT that the base should be (1 + 0.038/2), which produces a different result:
Thus, the compound amount, with principal $4000, at 3.8%, compounded 2x per year, for 7 years, is
A = $4000 ( 1 + 0.038/2) ^ (7*2), or $5205.93 (answer)
Bru what type of math is this ? need more info smhh do better
Answer:
9.647•10^7
Step-by-step explanation:
Take 96,470,000 and move the imaginary decimal before the first 0 and move it between the 9 and the 6 to get 9.647. However many numbers after the decimal is what you put above the 10 to get 10^7.
Answer:
y = -2x - 8
Step-by-step explanation:
Slope-intercept form is y = mx + b. Slope is m, and y-intercept is b. To do this, we substitute -2 for m and -8 for b. When we do this, we get y = -2x + -8. We can simplify this to y = -2x - 8.
