4x-2(x+y)=?
4*10-2(10-3)
40-2(7)
40-14
26
4x - 2 ( x + y ) = 4x - 2x - 2y
= 2x - 2y
= 2 ( x - y )
= 2 × ( 10 - (- 3) )
= 2 × 13
= 26

A plane is going to fly 400 miles at a planned speed of 570 mph. The flight will have an average headwind of w miles per hour the entire time, meaning the plane is flying directly against the wind. The time T, in hours, of the flight is a function of the speed of the headwind w, in mph, and can be modeled by
T(w) = 400/570 - W
a) What does T(150) mean in this situation?
b) At what value of w does the graph have a vertical asymptote? Explain how you know and what this asymptote means in the situation.

Answers
Answer:
< "less than sign"
Step-by-step explanation:
1/8 is 0.125 in decimal form.
1/2 is 0.5 in decimal form.
Therefore, 1/2 is greater than 1/8 so you would use the less than symbol (<) for a final answer of 1/8<1/3.
If the triangle and the rectangle have the same area, what is the value of n if m=6?
Answers
Answer:
n=3
Step-by-step explanation:
Triangle area: height*length*(1/2)
Rectangle area: width*length
Let's say x is the length, then our equation would be:
mx(1/2)=nx
we also know m is 6, so
6x(1/2)=nx
now we can solve for n
6x(1/2)=nx
3x=nx
3=n
n=3

Mateo, a 31-year-old nonsmoker ($5.50), wants to purchase $100,000 in coverage for himself and $75,000 for his spouse, who is female, 30 years old, and does not smoke ($3.50). What will the insurance premium be?
A. $30.50
B. $32.50
C. $35.50
D. $36.00
Answers
Answer: B. $32.50
Step-by-step explanation:
The premiums listed in brackets are for every $25,000 of coverage.
Mateo wants a $100,000 coverage so we need to divide this by $25,000 to see how much more he will have to pay:
= 100,000 / 25,000
= 4
Mateo will have to pay 4 times the $5.50 for himself:
= 4 * 5.50
= $22.00
For his spouse who requires $75,000, he will have to pay:
= 75,000 / 25,000
= 3
= 3 * 3.50
= $10.50
Total Mateo is to pay for both his spouse and himself is:
= 22 + 10.5
= $32.50

Solve the following simultaneous linear equations.
2x + y = 5
4x – 3y = -10
Answers
Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
