30 + 6p = 7 (p+ 6 ) -5<br> Please answer

melamori03 [73]

Answer: p=-7

Step-by-step explanation:

To solve for p, you want to isolate the variable, get p alone. You would use different algebraic properties to do so.

30+6p=7p+42-5

30+6p=7p+37

-7=p

p=-7

If the diameter of a sphere is 1 meter, then what is its surface area? Leave your answer in terms of π= 3.14

umka21 [38]

surface area = 4 x pi x r^2

diameter = 1 so radius = 1/2 = 0.5

4 x 3.14 x 0.5^2 = 3.14 meters^2

Steps to finding the line in the diagram with the format 'ax + by = c

1. Find the slope

To find the slope, we need any two points on the line --> (0,4) and (3,0)

$Slope = \frac{y2-y1}{x2-x1} =\frac{4-0}{0-3} =-\frac{4}{3}$

2. Set up, with any one point on the line and the slope, in point-slope form

$(y-y0)=m(x-x0)\\(y-4)=-\frac{4}{3} (x-0)\\y-4 = -\frac{4}{3} x\\\frac{4}{3}x+y = 4$

<u>Answer</u>: $\frac{4}{3}x+y = 4$

Hope that helps!
