Answer:
Brian Peters worked for total of 45 hours.
Step-by-step explanation:
Let the total number of hours worked be 'x'.
Now Given:
Hours spent on other projects = 18 hours.
Also Given:
60% of a week's time working on drawings for a new apartment building.
Hours spent on new apartment building =
We need to find the total hours worked.
Solution:
Now we can say that;
total number of hours worked is equal to sum of Hours spent on new apartment building and Hours spent on other projects.
framing in equation form we get;
Combining like terms we get;
Now Dividing both side by 0.4 we get;
Hence Brian Peters worked for total of 45 hours.
Answer: You will have points plotted at +3 on the y axis, and +3 on the x axis.
The attachment shows what your graph should look like.
Step-by-step explanation:
The intercept is where the graphed line crosses an axis.
To find the y-intercept, substitute 0 for x and solve for y:
0 + y = 3. Subtracting 0, you have y = 3
So you can plot a point at +3 on the y axis.
To find the x- intercept, substitute 0 for y, and solve for x
x + 0 = 3 Again, subtracting 0, x = 3
So plot a point on the x-axis at +3
Use the line tool to connect the two points.
Rise=16, run=7. Slope is rise/run, and therefore is 16/7. The run is considered to be the x coordinate. Since the x coordinate on the point is 21, we know it has moved 3 exact points away from the origin (21/7=3). We can use this movement of 3 exact points to determine the y coordinate as well. Since the rise (y) is 16 for every exact point on a graph, we know the graph has risen 48 units (16x3=48). So, the point ends up being (21,48). The rate of change is 16cm per 7 minutes, or 2.28cm/minute. The equation is Y=(16/7)X (no y intercept because the graph starts at the origin). The equation gives you the y value of 48 when x is equal to 21.
