Step-by-step explanation:
Here's the first question and how to solve the second.
So the first business start with 250, that's your b in slope.
y = mx + b
y = mx + 250
Now, they charge 14 an hour so that's your m.
y = 14x + 250
x is the number of hours it takes.
The second business is straight up 22 per hour, so it's just y = mx, where b is 0.
y = 22x VS y = 14x + 250
Try plugging in different numbers and seeing how much it take to level out!
Answer:
The answer is x = 14 the more expensive scarf
Step-by-step explanation:
x + y = 25
3 + y + y = 25 (x = 3 + y)
3 + 2y = 25
2y = 25 - 3
2y = 22
y = 22/2
y = 11
x = 3 + y
x = 3 + 11
x = 14 (the more expensive scarf)
(x,y) ; (14,11)
A. Since the rectangle can hold about three of those circles on the side, the area is 5x12=60. And since it gives you have the area of the circle, multiply by 2 so it would be 8. Therefore, 8+8+60=76, so it is 76 cm in total.
B. Since the rectangle can hold about three circles on the side the area is 6x3=18. And since it gives you the area of half the circle, multiply it by 2 so it would be 4. Therefore, 4+4+18=26 cm in total.
C. Since the rectangle can hold about three circles on the side the area is 6x6=36. And since it gives you the area of half the circle, multiply it by 2 so it would be 4. Therefore, 4+4+36=44 cm in total
Finally, A. Since in the beginning you multiply 4 by 3. Therfore your answer which is 72 must be multiplied by 2. So the answer is 144.
B.Since in the beginning you multiply 2 by 3. Therfore your answer which is 26 must be multiplied by 2. So the answer is 52.
C.Since in the beginning you multiply 2 by 3. Therfore your answer which is 44 must be multiplied by 2. So the answer is 88.
In the Final analysis, A. 144 cm, B. 52 cm, and C. 88cm
Answer: y=-3/4x
Step-by-step explanation:
The slope intercept form is when you use the equation y=mx+b (m is the slope and b is the y-intercept). First, let's find the y intercept. The y intercept is what y would be if x is 0. here, you can see that this particular line passes through the origin. So, the y-intercept is zero because when x passes through zero, y is also zero. Next, let's find the slope. The formula for slope is change in y/change in x. Let's randomly choose 2 points off this line. To make this a thousand times easier for us, let's choose the points (-4, 3) and (4, -3). Now, to find the change in y, let's find the difference between the 2 y coordinates we have chosen. To do this we just need to do -3-3, which gives us -6. Now let's find the change in x. To do this we will do the same thing we did to find the change in y but this time we'll use the x coordinates. We will do 4-(-4), which simplifies to 8. Now, we're almost done. Just divide the change in y by the change in x. You will get -6/8. This can be simplified to -3/4. So now we know our slope is -3/4 and our y-intercept is 0. Let's insert them into the equation. y=-3/4x+0. We know that we can just get rid of that 0 because 0 literally means nothing. So our final answer is y=-3/4x. Hope this helps!
