which of the following graphs represents a function?

Answer:

Yes

Step-by-step explanation:

Yes

Answer:

50

Step-by-step explanation:

Answer:

a number is 7

Step-by-step explanation:

First let's set up the equation:

8 + 2x = 22 (a number is replaced by x in this equation)

Now, to get x by itself and the answer, we need to cancel out the other numbers by adding, subtracting, multiplying, or dividing to both sides. I'm going to start with the eight, because it's the one with least complications.

8-8 + 2x = 22-8

We're left with 2x = 14

Now we divide both sides by two so x is by itself.

2x/2 = 14/2

Result:

x = 7

Answer:

-2/3 will be your answer

Step-by-step explanation:

I always like putting standard from into y=mx+b as you can just easily see the slope.

2x + 3y = 10

subtract 2x from each side

3y = -2x + 10

now to single out the 'y' divide by 3 on each side

y = -2/3 + 10/3

Hence, option A is your answer!

Answer:57

Step-by-step explanation:

Answer:

B) 0.57

Step-by-step explanation:

It says "given that you are in Sacramento", so hint: only look at the Sacramento row. Ignore everything else, you don't need it.

Then it asks what is the probability of a clear day, so you look at the "Clear" column from the Sacramento row. That would be 17 days.

Lastly, you just simply divide from the total days. 17/30 = 0.57

Answer:

b: only graph b is a function

Step-by-step explanation:

if you look closely graph a is in the middle of the boxes and all over the place, so the answer has to be b. Your welcome (pls give brainliest)

Let's solve for b.

y=(−5x12)(b)

Step 1: Flip the equation.

−5bx12=y

Step 2: Divide both sides by -5x^12.

−5bx12

−5x12

=

y

−5x12

b=

Answer:

f(3) = -6

f(-3) = -12

f(0) = -9

Step-by-step explanation:

Substitute each number for x.

f(3) = 3 - 9 = -6

f(-3) = -3 - 9 = -12

f(0 ) = 0 - 9 = -9

Answer:

{-6, -12, -9} is the range

Step-by-step explanation:

f(3) = 3 - 9 = -6

f(-3) = -3 - 9 = -12

f(0) = 0 - 9  =  -9

Answer:

C; The triangles may be congruent

Step-by-step explanation:

Here, we have two sides of the each of the triangles equal already

By congruency, we might have SSS or SAS

if SSS, this mean that all the sides are equal

Since we do not know the measure of the third side, we cannot say that they are not congruent or they are congruent

Also, we do not know the measure of the angles of the triangles

If we have an angle that is equal in the two triangles, then we can have congruency through SAS

But since we do not know how these measures, we use the word ‘may’

Answer:

t=3

Step-by-step explanation:

10/4=5/2t-4

Cross-multiply

10*(2t−4)=(5)*(4)

20t−40=20

Add 40 to both sides.

20t−40+40=20+40

20t=60

Divide both sides by 20

20t/20=60/20

t=3

Hope it's right!

Answer:

t=3

Step-by-step explanation:

[tex]\frac{10}{4} = \frac{5}{2t-4}\\\\[/tex]

cross multiply now,

Answer:

No. Lauren cannot buy the shirt. It costs $48 after the discount.

Step-by-step explanation:

Shirt Cost: $80

Money: $35

Discount: 40%

First, find the amount of the discount by finding 40% of the price. 40% is equal to 0.40 (or 40 divided by 100).

40% of $80 = 0.40 x 80 = $32

Since it's a discount, the final price is the original price minus the discount.

$80 - $32 = $48

So, after a 40% discount, the price is still $48. Lauren only has $35, so it will still be too expensive!
