2(x + 3) = 18
2x + 6 = 18
- 6 =
2x = 12
Divide 2
x = 6
The original statement is true!
the converse: If 2 lines do not intersect, they are parallel
the converse is false, the lines could be skew.
Hope this helped :)
The width of the enlarged photo is 9 inches.
Given:
Original length = 2 inches
Original width = 1 inch
Extended length = 18 inches
Extended width = ?
2:1 = 18:x
2x = 1*18
2x = 18
2x/2 = 18/2
x = 9 * extended width.
to check:
2:1 = 18:9
2*9 = 1*18
18 = 18
Answer:
Step-by-step explanation:
do the thing times 2
Answer:
Step-by-step explanation:
a.) When you have the following equation
To find the vertex you take the h value, change its sign (to positive in this case) and that will give you the x value. To find the y-value just take the z. This gives us (15,-100)
b.) The axis of symmetry is just the x value of the vertex which is 15
c.) I'm not too sure what this means but can tell you that it's concave up because there's no way x can be negative
d.)Because the a value is positive that means that the graph is concave up which means that it has a minimum. The minimum is just the y value of the vertex which is just -100
e.) I'm going to write this in interval notation. The domain is all the possible x values of the graph which is all real numbers or (-∞,∞). The range is all the possible y values. We know that the minimum is -100 which means all the possible y values are [-100,∞)
f.) This is obviously a parabola and because the graph is concave up and has a negative minimum there must be 2 x intercepts.
