Answer:
Step 1: Calculate. We calculate the square root of 62 to be: √62 = 7.87400787401181.
Step 2: Reduce. 7.87.
Step 3: Round. Round 7.87 so you only have one digit after the decimal point to get the answer: 7.9.

Answer:
standard form is Ax + by + c = 0
Step-by-step explanation:
add 5x to each side to get 5x + y - 2 = 0
Answer:
Option (D)
Step-by-step explanation:
Standard equation of a quadratic function is,
ax² + bx + c
Comparing this function with the given quadratic function,
f(x) = 2x² - 4x - 3
a = 2, b = -4 and c = -3
By using quadratic formula to get the value of x,
x = ![\frac{-b\pm \sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b%5Cpm%20%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
= ![\frac{-(-4)\pm \sqrt{(-4)^2-4(2)(-3)} }{2(2)}](https://tex.z-dn.net/?f=%5Cfrac%7B-%28-4%29%5Cpm%20%5Csqrt%7B%28-4%29%5E2-4%282%29%28-3%29%7D%20%7D%7B2%282%29%7D)
= ![\frac{4\pm\sqrt{16+24}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Cpm%5Csqrt%7B16%2B24%7D%7D%7B4%7D)
= ![\frac{-4\pm \sqrt{40}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-4%5Cpm%20%5Csqrt%7B40%7D%7D%7B4%7D)
= ![\frac{-2\pm \sqrt{10}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2%5Cpm%20%5Csqrt%7B10%7D%7D%7B2%7D)
Therefore, Susie made a mistake in step IV.
Option (D) is the answer.
Answer:
d.
Step-by-step explanation:
when you multiply the top equation by four you would equal out the y variable and be able to solve for x
