Solve the quadratic equations below.<br> 3x2 + 22x + 35 = 0

mestny [16]

Step-by-step explanation:

3x² + 22x + 35 = 0

(3x + 7)(x + 5) = 0

The question is unclear. The statement in the question "The probability that they will have a steak dinner is 50%"... seems extra so assuming that the question is the following:

Thursday is date night for Holly and David. Based on prior date nights, they will choose to go out 80% of the time. If they go out for date night, they will have steak for dinner 40% of the time, 10% of the time they will choose a pasta-based dinner, otherwise they will select something else. If they choose to eat at home they will only choose from pasta or steak. Answer the following questions.

(a) Determine the probability that they will have steak for dinner, given that they choose to have date night at home.

(b) Create a tree diagram based on the information given above.

Answer:

(a) 0.5

(b) attached in the picture

Step-by-step explanation:

(a) The first part is a conditional probability question. For that we can use the conditional probability method to find the answer. This is done in the picture attached below.

(b) Tree diagram is attached as a picture below showing all the possible outcomes.

1- out and steak

2- out and pasta

3- home and steak

4- home and pasta

3- home and steak and 4- home and pasta have equal probability.

Last month 7,482 people visited the local fair. This month, 6,123 people visited the museum. How many more people visited the mu

faltersainse [42]

There isn’t enough information to find the answer because the first number is telling how many people visited to local fair last month.
If you were to compare the number of people that visited the local fair last month and the number of people that visited the museum this month then the answer would be 1359 but, it’s not asking for that. This is why you cannot solve this problem

Using Substitution 4x-3y=-10 and x=1/4y-1

Alinara [238K]

Answer:

Then the solution is (-1/4, 3)

Step-by-step explanation:

Start by eliminating the fractional coefficient 1/4: multiply all 3 terms in the second equation by 4. This results in equation (b), below:

4x - 3y = -10 (a)

4x = y -4 (b)

Substitute y - 4 for 4x in equation (a):

y - 4 - 3y = -10

Combining like terms, we get -2y = -10 + 4, or -2y = -6, or y = 3.

Since x = (1/4)y - 1, if y = 3, then x = (1/4)(3) - 1, or x = 3/4 - 1, or x = -1/4

Then the solution is (-1/4, 3)

Can someone plsss help me :((

nevsk [136]

Answer:

Step-by-step explanation:

equation is y=2x+3

The point we have is (15,29)

i.e. x=15 and y=29

if we put x=15 in the equation we should get the value of y=29

y=2(15)+3

=30-3

=27

Here, we didn't get y=29 instead we got y=27

So the point (15,29) doesn't follow that equation
