Write an algebraic expression for product of 10 and the sum of x and 8

egoroff_w [7]

That would be the same as : 10 × (x + 8)

Okay, so it's asking for the product of 10, and the sum of 8 and k. Sum is the answer to an addition problem, so that would make the last of it 8 + k. And we'd be multiplying this with 10, so that would make it : 10 × (x + 8)

Y=6-x In this case, what would be the slope and y-intercept? I'm having a hard time trying to get it to the y=mx+b format.

frutty [35]

Answer:

Slope = $\frac{-1}{1}$ or -1

y = 6

Step-by-step explanation:

The equation given (y = 6 - x) is the same as saying

y = -1x + 6

Since we have a negative x variable and a positive 6 and would also be graphed the same. The only difference is that the second equation I just mentioned resembles the y = mx + b expression more. In this case the slope would be

Slope = $\frac{-1}{1}$ or -1

While the y-intercept would be

y = 6 - x

y = 6 - 0

y = 6

The width of a golden rectangle is 15 feet. Find the perimeter of the rectangle to the nearest foot.

topjm [15]

Answer:

79 ft

Step-by-step explanation:

Golden rectangle side ratios 1 : (1+sqrt5 )/2

(approx 1: 1.618)

15 + 15 + 2*15*1.618 = <u>~79 ft </u>

BUT perhaps the 15 is the 1.618 side

15/1.618 + 15/1.618 + 15 + 15 ~ 49 feet
