Answer:
(2,6)
Step-by-step explanation:
y = 2x + 2
Y = 3x
2x+2=3x
2x-3x+2=0
-x+2=0
-x=-2
x=2
y=3(2)=6
Answer: See explanation
Step-by-step explanation:
Your question isn't complete as you didn't give the sales tax percent. In order to solve the question, let's assume that the sales tax is 6%.
(a) What is the amount of sales tax that Mr. Speer has to pay?
This will be:
= Sales tax percent × Amount charged
= 6% × $300
= 6/100 × $300
= 0.06 × $300
= $18
The sale tax is $18
(b) What is the total amount Mr. Speer has to pay?.
The total amount will be the addition of the amount charged and the sales tax. This will be:
= $300 + $18
= $318
Y int.: (0,-1.2)
X int.: (-0.7,0)
Answer:
84
Step-by-step explanation:
is x 140
---- SO ... ------- = --------
of 60 100
(hit like pls)
60*140=100x
8400=100x
/100 /100

84 = x
Answer: 
Step-by-step explanation:
Observe in the figure given in the exercise that four right triangles are formed.
In this case you can use the following Trigonometric Identity to solve this exercise:
From the figure you can identify that:

Then, you can substitute values:

The next step is to solve for DE in order to find its value. This is:

Finally, rounding the result to the nearest tenth, you get that this is:
