Short Answerx1 = 4.8284
x2 = - 0.828
RemarkSubstitute the value for y from the first equation into the second equation. Multiply by 4 and then see if it factors out. Solve for x first and then y.
Step one Solve for y in the first equation. Subtract x from both sides.
y = 2 - x
Step TwoEquate the two ys.
2 - x = - 1/4x^2 + 3
Step ThreeBring the left side over to the right side.
0 = -1/4 x^2 + x + 3 - 2 Combine the like terms.
0 = -1/4 x^2 + x + 1
Step Four0 = -1/4 x^2 + x + 1 Multiply through by 4
0 = - x^2 + 4x + 4
Step fiveThis won't factor. The only thing you can do is use the quadratic equation for roots.
a = - 1
b = 4
c = 4
x = 2 +/- sqrt(4^2 * 2) / (- 2)
x = 2 +/- 4 sqrt(2) / - 2
x = 2 -/+ 2 sqrt(2)
x = 2 -/+ 2 *(1.414)
x = 2 -/+ 2.828
x1 = 4.8284
x2 = - 0.828
The distance between the points is 10
Answer:
The answer to your question is 84.8 cm
Step-by-step explanation:
Data
diameter = 27 cm
π = 3.14
circumference = ?
Process
To find the circumference of the flowerpot just find the radius and substitute the values in the formula.
1.- Find the radius
radius = diameter / 2
-Substitution
radius = 27/2 = 13.5 cm
2.- Formula
Circumference = 2πr
-Substitution
Circumference = 2(3.14)(13.5)
-Simplification
Circumference = 84.78 cm ≈ 84.8 cm
Answer:
The Product is negative three (-3)
WHILE
The number is negative one (-1)
Step-by-step explanation:
Since seven more than the product gives 4.
This means 7 + product = 4
By subtracting 7 from both sides we get product as -3.
And since the product of the number and 3 is equal the product
This means number X 3 = -3
By dividing three from both sides you get -1.
