3x+5<-22
Subtract 5 from both sides
3x < -27
Divide 3 on both sides
Final Answer: x < -9
Answer:
x=30°
y=62°
z=88°
Step-by-step explanation:
x+y+z=180
y+z=5x
so x+5x=180
6x=180
x=180/6=30
again z=y+26
so 30+y+y+26=180
2y=180-56=124
y=124/2=62
z=62+26=88

Answers: Choice B and Choice D</h3>
==========================================================
Explanation:
Standard form will always have the largest exponents listed first on the left side. Then as you move to the right, the exponents will decrease. Choice B shows this with the exponents counting down (3,2). Choice D is a similar story with the exponents counting down (9,2,1,0). Think of -6x as -6x^1, and also think of the 10 as 10x^0.
Something like choice A is a non-answer because the term with the largest exponent 3 is buried in the middle, and not at the left side. The exponents are not in decreasing order. Choice C can be ruled out for similar reasons.
Side note: the largest exponent is the degree of the polynomial. This only applies to single variable polynomials.
Answer:
Step-by-step explanation:
Mia is 2 1/2 years older than Chloe.
Mia is 12 years old.
<u>Chloe's age is:</u>
- 12 - 2 1/2 =
- 10 - 1/2 =
- 9 1/2
Allen is 6 1/2 years younger than Chloe.
<u>Allen’s age is:</u>
- 9 1/2 - 6 1/2 =
- 9 - 6 =
- 3
Answer:
I'm sorry, I'm not really certain of anything except part A
Step-by-step explanation:
Part A
First of all write the function.
Let x = the number of hours traveled. The y intercept is the value when x = 0
y = 2x + 50 Every 1 hour, the speed increases by 2 mph
(1) The y intercept is 0,50
(2) The car was travelling at 50 mph to begin with.
Part B
Average speed = total distance covered / time interval
Distance between 1 and 2 = 52 + (54 - 52)/1 = 54
Distance between 2 and 3 = 54 + (56 - 54)/1 = 56
Average = (54 + 56)/2 = 55
Part C
I don't see how Part C has any answer. It must change motion even if it winds up where it started from (in which case the velocity cannot be both 60 and 0 at the same time)
I think they want you to answer 0.
