Answer:
(5,18) & (-5 , 38)
Step-by-step explanation:
<h3>Solutions of linear and quadratic system of equations:</h3>
A linear equation represented by a line in a graph intersect the quadratic equation represented by a parabola zero, one or two times.
f(x) = x² - 2x + 3 -------------------(I)
f(x) = -2x + 28 ---------------------(II)
x² - 2x + 3 = -2x + 28
x² - 2x + 2x + 3 - 28 = 0
x² - 25 = 0
x² = 25
x = √25 = √5*5
x = ± 5
Plugin x = 5 in equation (II),
f(5) = -2*5 + 28
= -10 + 28
= 18
(5 , 18)
Plugin x = -5 in equation (II),
f(-5) = -2*(-5) + 28
= 10 + 28
= 38
(-5, 38)
Answer:
A. Divide 14 by 2, because each pint has 2 cups
Step-by-step explanation:
Formula:
Divide the volume value by 2
The thousandth is three places to the right of the decimal point. Since you don't have a number there, rounding 3.28 to the thousandth would make it 3.280
Answer: 8.3
Work:
Sum = Addition
So, 1.5+6.8=__
We know that 1+6= 7
And .5+.8= 1.3 (5+8=13 so 1.3)
And 1.3+7=8.3
Answer is 8.3
