Answer:
x = - 8, x = 6
Step-by-step explanation:
Given the 2 equations
x² + y² = 100 → (1)
y = x + 2 → (2)
Substitute y = x + 2 into (1)
x² + (x + 2)² = 100
x² + x² + 4x + 4 = 100
2x² + 4x + 4 = 100 ( subtract 100 from both sides )
2x² + 4x - 96 = 0 ( divide through by 2 )
x² + 2x - 48 = 0 ← in standard form
(x + 8)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 6 = 0 ⇒ x = 6
So,
53,879 rounded to the nearest hundred:
If the number in the tens place is greater than or equal to 5, then round up. If not, round down.
7 is greater than or equal to 5, so round up.
53,879 --> 53,900
Answer:
D. $0.05
Step-by-step explanation:
Don't worry! I'll help you through it.
So we just have to find the unit rate (price) per apple.
$4 divided by 5lbs bag = $0.80 so, The 1st bag is $0.80 an apple.
$6 bag divided by 8lb = $0.75 an apple.
Now, simply subtract
0.80
-0.75
0.05
So your answer is D, $0.05
Have a great day!

Answer:
0
Step-by-step explanation:
Distance between two points is the slope .
Slope =change in y/change in x
Given (-26,0) and (95,0)
x1 = -26
y1 = 0
x2 = 95
y2 = 0
Slope = y2 - y1 / x2 - x1
0-0/95-(-26)
0-0/95+26
0/121
0
