First, we need to get the slope of the equation of the train tracks. We can transform the given equation into the slope-intercept form.
4x +2y = 16
y = -2x +8
The slope of the equation is -2.
A perpendicular line will have the same slope but the opposite sign.
So, the slope of the line of the train crossing is 2. Since, it will pass through the point (8,15), the slope-intercept form can also be used to solve for the equation.
y = mx + b
The slope is 2, so m=2. We solve b by substituting the coordinates.
15 = 2(8) +b
b = -11
The equation is now,
y = -2x - 11
Or it can also be expresses as:
2x - y = 11
Answer:A
Step-by-step explanation: because there is an association with the child’s hight and age so the answer is A ( plus I have did this before and got it wrong and the actual Answer was A when I picked B
Answer:
The measure of angle y is 90°
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
so
m∠y=(1/2)[180°] -----> because the diameter divide the circle into two equal parts
so
m∠y=90°
m∠x=(1/2)[148°]
m∠x=74°
Answer:
Step-by-step explanation:
hello :
x+6 because : (x+6)(x+1) =x²+x+6x+6=x² + 7x + 6)
You don't have the answer choices but if there were no decomposers within an ecosystem, some plants could die due to a shortage of nutrients
