The equation of a line is y = 3x + 8 what is the gradient of the line

Answers

Answer: 3

Step-by-step explanation:

We can find the gradient, or slope, of the line by looking at the equation. This equation is given in slope-intercept form equation which is y = mx + b, where m is the gradient/slope.

y = 3x + 8

y = 3x + 8 ➜ the gradient is 3

The gradient of the line is 3.

How to find the gradient

The equation of line given is y = 3x + 8.

To find the gradient of the line, compare it with the standard slope-intercept form y = mx + b, where m is the gradient (slope).

Comparing the equations:

m (gradient) = 3

Hence, the gradient of the line is 3.

BRAINLIEST The price of a leather coat is $256. The store will cut this price in half each day until the price drops below $20. How much will it cost on the day the price drops below $20?

Answers

Okay, the price before was $256, then it goes down to below 20. I think the answer is $12.80, because I said 256 ÷ 20 = 12.8, which can be turned into $12.80

Brainliest if it is correct!

price drop is following this pattern

256, 128, 64, 32, 16 . . . .

so you can see 16 is the price which is less than 20 $. you can also solve it by using GP

Jake mowed 216 sq.yd. of lawn in 3 hr. Ricky mowed 108 sq.yd. of lawn in 2 hr.Can you fill in the values for Ricky?

Ricky’s square yards mowed:

Ricky’s time (hr.):

Answers

Final answer:

To find Ricky's values, set up a proportion and solve for Ricky's square yards mowed and time.

Explanation:

To find the values for Ricky, we can use a proportion. Since Jake mowed 216 sq.yd. in 3 hr, we can set up the proportion as 216/3 = Ricky's square yards mowed/2. To solve for Ricky's square yards mowed, we can cross multiply and divide: 216 * 2 = 3 * Ricky's square yards mowed. Therefore, Ricky's square yards mowed = 432 sq.yd. Next, we can find Ricky's time by setting up another proportion: 216/3 = 432/Ricky's time. Cross multiplying and dividing gives us Ricky's time = 6 hr.
