During the summer , you want to earn at least $150 per week. You can earn$10 per hour working for a farmer, and $5 per hour babysitting.you can work at most 25 hrs per week. -write a system of linear inequalities that models the situation-solve your system,and tell how many hours per week you would work babysitting
-if you work 10hrs per week on the farm and 12 hours per week babysitting,will you meet your goal?
Answers
y = nr. hrs. babysitting;
x + y <= 25;
10x + 5y >= 150
a) Solve the system => one of the solution is x =5; y = 20(babysitting)
b) 10 + 12 =22 <= 25; 10*10 + 5*12 = 160 >=150.
10x+5y>=150 => 10 x >= 150- 5y :5 => 2x >=30-y => 30-2x <= y
x+y<= 25 =>
y>=30-2x
y<=25-x

A. ) f(x) has one real zero at –2 because the graph of the function has an intercept at (0, –2).
B. ) f(x) has two real zeros at –4 and –2 because the graph of the function has intercepts at (–4, 0) and (0, –2).
C. ) f(x) has no real zeros because the graph of the function does not pass through (0, 0).
D. ) f(x) has one real zero at –4 because the graph of the function has an intercept at (–4, 0).

The last 6 is the thousandths place. If it is 5 or bigger then the number to the left is rounded up. If its lower than 5 you round down
Since 6 is over 5 we tound up

Hi Brainiac
3x+2y=7
y=-3x+11
We need to solve y=-3x+11 for y
Now let's start by substitute -3x+11 for y in 3x+2y=7
3x+2y=7
3x+2(-3x+11)=7
-3x+22=7
Now add -22 to both sides
-3x+22-22=7-22
-3x=-15
To find the value for x we need to divide both sides by -3
-3x/-3= -15/-3
x=5
Now we have the value for x :)
Let's find the value for y by substitute 5 for x in y=-3x+11
y=-3x+11
y=-3(5)+11
y=-4
Here you go :)
The answer is D
Good luck :0
