1st multiply the top equation by -1 to get -3x - y = -17 then add the 2 equations together to get:
4x + y - 3x - y = 18 - 17
x = 1 (simplified down)
Now plug the 1 into either equation
4(1) + y = 18
4 + y = 18
y = 18 - 4 = 14
Your point is (1, 14)
Answer:
a)
b) 3 terms in simplified expression
c) 3 is leading coefficient
d) 2 is the degree of simplified expression
Step-by-step explanation:
We need to perform subtraction of
a) What did you need to distribute to the second polynomial to rewrite?
We need to multiply - sign with the terms inside the bracket.
Perform subtraction. Then, answer:
b) How many terms in the simplified expression?
There are 3 terms in the simplified solution
c) What is the leading coefficient of the simplified expression?
The leading coefficient is the coefficient with highest degree. The highest degree is 2 so, leading coefficient is 3
d) What is the degree of the simplified expression?
The highest degree is considered as the degree of simplified expression. In our case the highest degree is 2
Answer:
Step-by-step explanation:
Answer:
Size 9
Step-by-step explanation:
The range is the highest value - the lowest value.
If the range is three, therefore the highest value - lowest value is 3
If 2 people in the family wear size 6, we can count that as 1 value. Since the question says that his shoe size can't be 3, so we let x be the number with the higher value.
x - 6 = 3
x = 9
Therefore Lee's shoe size is 9
You use the tan/cos/sin rules
So we know that the hypotenuse=46.8, opposite=44
We can use sin (negative) to find it
sin^-1=opp/hyp
sin^-1=44/66.8
=70 degrees
Hope this helps!! :)
