Answers

Hello, lets solve this!

$\sf 7p+8p-12=59\n\n\sf Add~like~terms}\n\n15p - 12=59\n\nAdd~12~on~both~sides\n\n15p -12 + 12 = 59 + 12\n\n15p = 71\n\nDivide~15~on~both~sides\n\n\boxed{\bf{p = (71)/(15) = 4.73333333}}$

Hope I helped! If you have any other qestions or would like further explantion just let me know!! :)

Combine like terms first.
7p+8p=15p
15p-12=59
Now add 12 from both sides.
15p=71
Now divide both sides by 15.
p=4.7333333333

In the coordinate plane, what is the length of the line segment that connects points at (0, −1) and (−7, −2) ?Round to the nearest hundredth.

Answers

Distance = √(y2-y1)² + (x2-x1)²
d = √(-1+2)² + (0+7)²
d = √1² + 7²
d = √1+49
d = √50

In short, Your Answer would be √50 or 7.07 units

Hope this helps!

distance formula!!!!! yay i've done this umpth manytimes today for people so if you dont know distance formula is square root of (x1-x2)^2+ (y1+y2)^2.
0-(-7) -1-(-2)
7^2 + 1^2
49+1
sqr. root of 50
appx. 7.07 or the closest to it

What is the sum of all integers x that satisfy 1 < (pi -1 )x < 10?

Answers

Answer:

Step-by-step explanation:

pi - 1 = 3.14 - 1 = 2.14

x has to be an integer, and the result must be greater than 1.

1 works.

1 < 2.14*1 < 10 2.14 is between 1 and 10.

2 works

1 < (2.14)*2 < 10

1 < 4.28 < 10

3 works

1 < 2.14 * 3 < 10

1 < 6.42 < 10

4 might work

1 < 2.14*4 < 10

1 < 8.56 < 10

and it does work.

5 can't work

1 < 5 * 2.14 < 10

1 < 10.7 < 10 is not true.

Answer: 1,2,3,4

Answer:

Step-by-step explanation:

pi is 3.14...

pi - 1 is 2.14...

question becomes 1<2.14x and 2.14x < 10

1/2.14 < x, 0.46... < x

x < 10/2.14, x < 4.67...

combining

0.46< x < 4.67

x can be 1, 2, 3, 4

Given ƒ(x) = 3x - 1 and g(x)= -x + 6, find ƒ(-2) + g(5).
-6
6
8

Answers

This should be the answer

Given ƒ(x) = 3x - 1 and g(x)= -x + 6, find ƒ(-2) + g(5).

f(-2) = 3(-2) =-6 -1 = -7

g(5) = -(5) = -5 +6= 1

-7+1= -6

Answer: -6

f(x) = 3x - 1
g(x) = -x + 6

f(2) + g(5) = (3(2) - 1) + (-(5) + 6)
f(2) + g(5) = (6 - 1) + (-5 + 6)
f(2) + g(5) = 5 + 1
f(2) + g(5) = 6

The answer is C.
