Answer:
15
Step-by-step explanation:
5x4=20
5x-1=-5
20-5=15
598.61 rounded to the nearest tenth is 598.60 I got the answer by rounding ;P
jk
You just have to look at the tenths place (the place your rounding to) which is .6 The look to the number next to it on the right (.01) If that number on the right is 4 or less, the number youre rounding to stays the same (but all the numbers to the right of it turn into zeros.) If the number to the right is 5 or more, than add 1 to the number your rounding to. But here the number to the right is less than 4 so the answer is 598.60.
For standard form, we have to rearrange this equation. We want the variables on one side (also called Slope Intercept Form or Ax + By = C)
Subtract 7x from both sides and 4 from both sides to "swap" the variables and the constant number.
This gives us:
x^2 - 7x = -4
it's equal because adding a 0 to 5.75 and making it 5.750 would be the same
