Use substitution
x + x + 4 = 2
2x = -2, x = -1
Y = -1 + 4, y = 3
Solution: (-1, 3)
Answer:
Slope: 5
Point:
Step-by-step explanation:
We have been given that a line's equation is point-slope form . We are asked to find the slope of the line and a point on this line that is apparent from the given equation.
We know that point-slope form of an equation is in form , where
m = Slope of line,
= Coordinates of points the is on the line.
Upon looking at our given equation, we can see that , therefore, the slope of the line is 5.
We can also see that , therefore, point is one the given line that is apparent from the given equation.
The gardeners should buy 54 white hydrangeas and 88 pink hydrangeas altogether.
Step-by-step explanation:
Let,
Number of white hydrangeas = x
Number of pink hydrangeas = y
According to given statement;
In first bed
x+y = 40 Eqn 1
In second bed
2 times the number of white hydrangeas and 3 times the number of pink hydrangeas as in the first bed.
2x+3y=102 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 3 from Eqn 2
Putting y=22 in Eqn 1
Number of white hydrangeas altogether = x+2x = 3x = 3(18) = 54
Number of pink hydrangeas altogether = y+3y = 4y = 4(22) = 88
The gardeners should buy 54 white hydrangeas and 88 pink hydrangeas altogether.
