Answer:
$3.50
Step-by-step explanation:
Let x be the cost of per gallon gas.
We have been given that it costs Raquel 5$ in tolls to drive to work and back each day, plus she uses 3 gallons of gas. It costs her a total of 15.50$ to drive to work and back each day.
We can represent this information as:
Therefore, Raquel is paying $3.50 for per gallon gas.
Answer:
1st option is the answer
Step-by-step explanation:
blue line: slope is 1 and y-intercept is 1; therefore equation is y= x + 1
red line: slope is -1 and y-intercept is -3; therefore equation is y= -x - 3
Answer:
2x+7/6
Step-by-step explanation:
an normal function would be mapping x to y, since this is the inverse we would map y to x
f(x) and y are the same so I will take f(x) as "y"
1)3x-7/2=y
3y-7/2=x
solve/isolate "y" in 3y-7/2=x to get the value of "y"
3y-7/2=x
add "7/2" to both sides
3y-7/2+7/2=x+7/2
3y=x+7/2
divide both sides by "3"
3y/3=x/3+7/2/3
simplify:
y=2x+7/6
hope this helps!
Answer:
, 
Step-by-step explanation:
Part a) Find the sin(A)
we know that
In the right triangle ABC
----> the sine of angle (A) is the opposite side angle (A) divided by the hypotenuse
substitute the values
Part b) Find the cos(A)
we know that
In the right triangle ABC
----> the cosine of angle (A) is the adjacent side angle (A) divided by the hypotenuse
substitute the values
