Answer:
-7
Step-by-step explanation:
Answer:
{7, 8, 9, 10}
Step-by-step explanation:
Having worked 4 hours babysitting, Zoé has already earned 4×$7 = $28, so only needs to earn $130 -28 = $102 more.
At $15 per hour, it takes her $102/$15 = 6.8 hours to earn that amount. In order to keep her total hours to a maximum of 14, Zoé cannot work any table-clearing hours more than 14 -4 = 10. The possible solutions for Zoé's hours doing table clearing are ...
{7, 8, 9, 10} . . . . hours
_____
We have assumed Zoé must work whole numbers of hours.
Answer:
60°
Step-by-step explanation:
all angles add up to 360,so 360-(90×2)=180
180÷3=60°
Answer:
y = -4
Step-by-step explanation:
We can find the equation of a line that goes through two given points on the plane by finding 1) the slope of the segment that joints the two points, and using the coordinates of one of the given points, and use this information in the "point-slope" form of the line.
To find the slope of the segment that joins the two points, we use the general equation for the slope given two coordinate pair points as:
In our case, using the given (-3,-4) as , and (1,-4) as , we get the following slope:
Therefore, the slope is zero (this means we are dealing with a horizontal line.
Now we complete the work by using the point-slope form of a line which is:
Using one of the given points (let's say (1,-4) as , and the slope (0) that we just obtained, we get the following equation for the line in question:
So y = -4 is the expression for the line
