If 40% are boys, 60% are grills.
As fractions:
4/10 = 2/5 are boys
6/10 = 3/5 are grills
70% or 7/10 of the boys arrive by car:
(2/5)(7/10) = 14/50 = 7/25
And 60% or 3/5 of the grills arrive by car:
(3/5)(3/5) = 9/25
So in total we have 7/25 + 9/25 = 16/25 = 64/100 = 64%
64% chance that a child arrives by car.
The value of x and y is y= 3/4 and x= -1/2
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given equations:
2x+8y=5........(1)
24x-4y=-15...........(2)
Multiply equation (1) by 12, we get
24x + 96y = 60.....(3)
From (2) and (3), we get
-4y-96y= -15-60
-100 y= -75
y= -75/-100
y= 3/4
and 2x+8y=5
2x + 8 (3/4) =5
2x + 6 = 5
2x= -1
x= -1/2

Zeros are
Write in factor form and solve
- (x-0)(x-(-3))(x-(-4))=0
- x(x+3)(x+4)=0
- x[x(x+4)+3(x+4)]=0
- x(x²+4x+3x+12)=0
- x(x²+7x+12)=0
- x³+7x²+12x=0
Points given (-2,16)
Solve for n
On solving we get
So the function is
- y=-4(x³+7x²+12x)
- y=-4x³-28x²-48x
