Was there a typo in the possible answers by any chance? B is closest to the possible answer, but only if the division sign was a multiplication sign.
102 <span>÷ 6 = 17
102 </span><span>÷ 17 = 6
17 x 6 = 102
6 x 17 = 102</span>
Answer:
f(x) = 12x = 10
Step-by-step explanation:
We need a linear equation in the slope-intercept form.
y = mx + b
where y = total pay, m = hourly salary, x = number of hours worked, and b = y-intercept, or initial value
Let's look in the table.
1 hour: $22
2 hours: $34
The difference in pay between 1 hour and 2 hours is $34 - $22 = $12.
The difference in time between 1 hour and 2 hours is 1 hour.
In 1 hour he earns $12. That means the slope is 12.
We know he earns $22 for working a total of 1 hour.
Start at 1 hour and $22 on the table.
Subtract 1 hour from 1 hour to get 0 hours.
Subtract $12 form $22 to get $10.
That means for 0 hours he gets $10. b = 10
The equation is
y = 12x + 10
In function form, we have:
f(x) = 12x = 10
Answer:
Perpendicular.
Step-by-step explanation:
4x - 7y = 9 ---> 7y = 4x - 9 ---> y = 4/7 x - 9/7, slope= 4/7
7x + 4y = 5 ---> 4y = - 7x + 5 ---> y = - 7/4 x + 5/4, slope = - 7/4
lopes are negative-reciprocal , so these lines are perpendicular.

Answer:
(-4,-2)
Step-by-step explanation:
first u should chose a variable to eliminate and i choose Y
y=5/2x+8-y=-1/4x-3
get a common denominator
5/2= 10/4
-1/4=-1/4
the equation i will change a little because we are subtracting
10/4x+8+1/4x+3
11/4x+11
solve for the remaining variable which is X
subtract 11 on both sides
0-11=11/4x+11-11
-11=11/4x
multiply both sides by 4/11
-11 times 4/11= 11/4x times 4/11
x=-4
then substitute the variable in one of the equations and i choose y=5/2x+8
5/2(-4)+8= y
-20/2+8= y
-10+8=y
y=-2
