The problem states that the first minute is $1.25. Thus, Choices A and C are eliminated.
The problem also says that for each additional minute, the caller will be charge $0.75.
If the total number of minutes on the phone is some time m. Then the additional minutes, excluding the first minute will be some shorter time (m - 1).
Your only answer is Choice B.
In fact, Choice D is overcharging you
Method #1
Starting with the expression
2x(x2 + 3xy + 6y2)
We multiply out the expression
2x3 + 6x2y + 12xy2
Choice B is the correct answer.
Another way to look at this is eliminating the impossible answers.
Choices C and D are not possible because the first x term is multiplied by an x2 term yielding an x3 term as the first term of the expression.
Choice A is not possible because the last term must be an xy2 term.
The only correct answer is Choice B.
We start with
5x + (5/3)x ≤ -2x - (2/3)
Group like terms…
7x ≤ (-7/3)
Sovling for x
x ≤ (-1/3)
Choice B is the correct answer.
We are provided two points of information. We can use this data to eliminate impossible answers.
The y-intercept is located at y = 6. This eliminates Choices A and C.
The x-intercept x = 3 is found on the left side of the positive y-intercept. Thus, the slope must be negative. Choice is eliminated.
Our only choice left is Choice D.
Why is donald trump still rich?
Because he understands this chart!
Choice D is eliminated because it outside of the time range of the chart.
Choice B is wrong because growth of money is exponential.
Only choice C provides a good summary of the information in the graph.
Choice C is the only answer.
1.87 * 10-1 oz = 0.187 oz
1.87 oz / 10 = 0.187 oz
Choice B is the correct answer.
Rational numbers include fractions and decimals with repeated endings. They may also include integers.
(5,6,89,-33,-98)
Integers include negative numbers, positive numbers and zero.
(…-2,-1,0,1,2…)
The best way to represent the number of people is using whole numbers.
(1,2,3,4….)
Irrational numbers include square roots and numbers like p (pi).
(3.14159…..)
Irrational numbers cannot be classified as numbers representing the number of people in a room.
Choice D is the correct answer.
The angle is 84o.
The angle is not a right angle. A right angle is exactly 90o. Choice B is eliminated.
The angle is not an obtuse angle. An obtuse angle is greater than 90o. Choice C is eliminated.
Choice A makes no sense. Why do you need to measure another angle?
Choice D is the only correct answer. The angle is acute (less than 90o).
We start with
2(3x - 2y) + 4y
We multiply out the expression
6x - 4y + 4y
We group like terms (4y - 4y = 0)
6x - 0
Our final expression is simply is
6x
The problem states that the minimum allowed slope is -7/10. (-.70)
So, we are looking for steeper (more negative) slopes than the architect’s recommendation.
Choice A is -5/7. (-.71) APPROVED!
Choice B is -14/15. (-.93) APPROVED!
Choice C is -3/5. (-.60) REJECTED!
Choice D is -7/9. (-.78) APPROVED!
Choice C is the correct answer.
