Which equations have infinitely many solutions? MORE THAN ONE
2 answers:
Answer:
B and D
Step-by-step explanation:
When both sides of an equation are same then the equation has infinitely many solutions
x-3x=-2x+4
Both sides are not same.
LEts simplify the left hand side. cancel out 3 at the top and bottom
x- x = 0
0=0 , so the equation have infinitely many solutions.
Both sides are not same , so does not have infinite solutions
Cancel out 3 at the top and bottom
3x + 2 -x = 2+2x
2x+2 = 2+2x
Both sides are same , so the equation have infinitely many solutions.
Both sides are not same .

P(X = 0) = 0.25
P(X = 1) = 0.75
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The probability distribution of X.
3 red balls out of 4, one picked, so we can have either 0 red balls or 1 red ball. The probability disitribution is the probability of each outcome.
An inequality that represents Denise's goal in terms of the number of hours spent running 'h'
Given :
Denise wants to burn at least 5000 calories a week through running.
she can burn 550 calories per hour
Let 'h' be the number of hours spent
In 1 hour she can burn 550 calories
In 'h' hours she can burn 550h calories
Given that she want to burn atleast 5000 calories in a week
Burn atleast 5000 calories means <=5000 calories
So , the inequality that represents Denise's goal is
calories burn in h hours <= 5000 calories
