What is the constant expression of 3m+7

1 answer:

qwelly [4]3 years ago

7 0

The constant in an algebraic expression is the only term that cannot be changed.

Terms with variables are not constants as their values can changed as the variables change.

Our equation is 3m+7

M is a variable. Therefore the term '3m' is not the constant.

This leaves us with the term '7'. There is no variable present in this term.

'7' is the constant in this equation.

Answer:

0.45 = 45% probability that the member uses the golf course but not the tennis courts

Step-by-step explanation:

I am going to solve this question using the events as Venn sets.

I am going to say that:

Event A: Uses the golf courses.

Event B: Uses the tennis courts.

5% use neither of these facilities.

This means that $P(A \cup B) = 1 - 0.05 = 0.95$

75% use the golf course, 50% use the tennis courts

This means, respectively, by:

$P(A) = 0.75, P(B) = 0.5$

Probability that a member uses both:

This is $P(A \cap B)$ . We have that:

$P(A \cap B) = P(A) + P(B) - P(A \cup B)$

So

$P(A \cap B) = 0.75 + 0.5 - 0.95 = 0.3$

What is the probability that the member uses the golf course but not the tennis courts?

This is $P(A - B)$ , which is given by:

$P(A - B) = P(A) - P(A \cap B)$

So

$P(A - B) = 0.75 - 0.3 = 0.45$

0.45 = 45% probability that the member uses the golf course but not the tennis courts

Find the real or imaginary solutions of the equation by factoring, x^3+64=0

Ket [755]

Answer:

x=-4

Step-by-step explanation:

x^3+64=0

Subtract 64 from each side

x^3 +64 -64 = -64

x^3 = -64

Take the cube root of each side

(x^ 3)^1/3 = (-64) ^1/3

x = -4

What is the equation of a line that has a slope of 2/5 and passes through the<br> point (-5,5)? *

iren2701 [21]

Answer:

y = 2/5x + 7

Step-by-step explanation:

substitute 2/5 in for m and (-5,5) in for (x,y) respectively to find the y intercept

y=mx+b

5 = 2/5(-5) + b

5 = -2 + b

add 2 to both sides to solve for b (y intercept)

b = 7

therefore the equation for the line will be...

y = 2/5x + 7
