Answer: y = -2/5x + 3
Step-by-step explanation:
The formula for a line is: y = mx + b.
<em>m</em> is the slope of the line. We calculate this by looking at how many units the line travels vertically over how many units the line travels horizontally, or rise over run. In this example, we can see that the line goes down 2 units for every 5 it goes to the right, meaning the slope is equal to -2/5.
<em>b</em> is the y-intercept, or where the line crosses the y-axis. In this example, the line crosses the y-axis at (0, 3) making the <em>b</em> value equal to 3.
Therefore, the equation for this line put together is y = -2/5x + 3.
Answer: One batch of Fried rice costs $3.55
Step-by-step explanation: One batch consists of 5 pounds. One pound is 71 cents. We have to multiply 71 by 5. The product of 71 and 5 is equal to 355 cents. One batch of Fried Rice costs 355 cents or $3.55
Answer:
5 units
Step-by-step explanation:
Area of triangle = 1/2 × base × height
30 = 1/2 × 12 × height
Height = 30 × 2/12 = 5 units
The formula for the volume of a box (assuming that it is in the shape of a cube) is <u>V=B^3</u>.
12=B^3
Now, do the cube root of 12 to find each dimension, all dimensions will be equal as it is a cube.
B= about 2.29 (when doing on a calculator keep full answer and do not round)
Now to find the volume of box B, multiply each dimension by 5
5(2.29...) times 5(2.29...) times 5(2.29...)
=1,500 m^3
Hope this helps!
