Step-by-step explanation:
Answer:
Step-by-step explanation:
Step 1: Subtract -2x from both sides.
x2+x−7−−2x=−2x−−2x
x2+3x−7=0
For this equation: a=1, b=3, c=-7
1x2+3x+−7=0
Step 2: Use quadratic formula with a=1, b=3, c=-7.
x= −b±√b2−4ac / 2a
x= −(3)±√(3)2−4(1)(−7) / 2(1)
x= −3±√37 / 2
x= −3/2 + 1/2 √37 or x= −3/2 + −1/2 √37
Answer:
x= −3/2 + 1/2 √37 or x= −3/2 + −1/2 √37
Answer:
0.015
Step-by-step explanation:
because i divided the answer by 10
Answer:
1.5
Step-by-step explanation:
the slope is regarded as :
= ![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
this is also known as the <em>gradient </em>, meaning the differences of two y values divided by the differences of the two corresponding x values
take two values on the slope and put in the form ( x,y)
we shall use two points A and B
A = (80 , 100)
B = (20 , 10)
now use the formula:
![\frac{10-100}{20-80}](https://tex.z-dn.net/?f=%5Cfrac%7B10-100%7D%7B20-80%7D)
=![\frac{-90}{-60}](https://tex.z-dn.net/?f=%5Cfrac%7B-90%7D%7B-60%7D)
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
also can be represented into an integer form
answer is <u>1.5</u>
