What are the zeroes of f(x) = y2 - 2x - 3?
Answers
Answer:
Step-by-step explanation:
Product = -3
Sum = -2
Factors = -3 , 1
y² - 2y - 3 = y² + y - 3y - 3
= y( y + 1) - 3(y + 1)
= (y +1) (y - 3)
Answer:
x=y^2/2 - 3/2

Answer:
x = 5°
Step-by-step explanation:
We know that in a triangle, the measure of an exterior angle is equal to the sum of its two remote interior angles, therefore:
7x + 4 + 61 = 20x
7x + 65 = 20x
13x = 65
x = 5°
Answer:
Solution given:
61°+(7x+4)°=20x [ exterior angle is equal to the sum of two opposite interior angle]
65+7x=20x
65=20x-7x
13x=65°
x==5°
value of x=5°

Remark
Let the shorter base = x
Let the longer base = 3x
h = 5
Area = 60
Formula
Area = (b1 + b2)*h /2
Solution
60 = (x + 3x)*5 / 2 Multiply both sides by 2
2*60 = (x + 3x)*5 Combine like terms
120 = 4x *5
120 = 20x Divide by 20
120/20 = x
x = 6
Therefore the two bases are
x = 6
3x = 18
