Answer:
A. 2/3
Step-by-step explanation:
Plot the points, so you visualize rise/run.
When you start at the point (-3,8) it rises 2 then moves 3 to the right to get to the point (0,10). Then it rises 2 and moves 3 to the right to the point (3,12).
Answer:
x = 4
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, as shown in the figure.
Equating their measures, we have ...
∠A = ∠C
8x -7 = 25 . . . . substitute the given expressions
8x = 32 . . . . . add 7
x = 4 . . . . . . divide by 8
It helps when you count decimal places to line up the numbers
The shape is a trapezoid and its area formula is:
A =
h
a is a base length, b is another base length and h is the height.
A =
(10.8)
A = 81
So the area of the shape is 81yd²
Remark
Remove the brackets. Then solve as a normal inequality.
Solution
4(x - 3) - 2(x - 1) > 0
4x - 12 - 2x + 2 > 0 Combine like terms on the left
4x - 2x - 12 + 2 > 0
2x - 10 > 0 Add 10 to both sides
2x > 10 Divide by 2
x > 10/2
x > 5
Answer: B
Discussion
C and D are both true but these questions always assume that you are going to pick the lowest value that will allow the inequality to be true. x> 7 and x>14 will be included in x>5
