Multiply both sides by 3
Simplify the numerators
Multiply both sides by 6
Simplify the numerator
Multiply both sides by x
12x - 18 = 15x Subtract 12x from both sides
-18 = 3x Divide both sides by 3
-6 = x Switch the sides to make it easier to read
x = -6
Check your answer by plugging -6 in for the x in the original problem:
Plug in -6 for x
Change
to
so all denominators are the same
Change
to
for easier work
Subtract the numerators (4 - (-1) )
=
So,
x = -6 .
Answer:
Concave down
Y-intercept: (0,-3)
X-intercepts: (-1,0) (-3,0)
Vertex: (-2,1)
Answer:
FALSE
Step-by-step explanation:
Assuming ZY is a tangent, the measure of the arc will be twice the measure of the angle. If the angle ZYX is 23°, the measure of arc YX will be 46°.
12,000 pounds, 1 ton = 2000 pounds
From the graph, it is obvious that the trend is decreasing from 100 on day 2, to 1 on day 10. So, the answer could either be A or C. The question would be how fast is it decreasing? To illustrate this, let's find the difference of consecutive data:
100 - 26 = 74
26 - 6 = 20
6 - 2=4
2-1=1
It must not be an additive rate because there is no common difference. Let's illustrate if the trend is in multiplicative rate:
100/26 = 3.85
26/6 = 4.33
6/2 = 3
2/1 = 2
More or less, they have a common divider. Hence, the decreasing rate is in multiplicative rate. The answer is A.
