1(whole number) 4/6 (fraction) + 2(Whole number) 1/4 (fraction)

Answers

Answer:

Step-by-step explanation:

Answer:

answer is 3 11/12

Step-by-step explanation:

1 4/6 =10/6

2 1/4=9/4

when adding fractions that are do not share a common denominatour you have to find a common multiple

which in this case is 12

so 9/4 timesed the top and the bottom by 3 gives you 27/12

and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)

what is the coordinate for
x = 5
2x + y = 10

x =? y =?

Answers

Step-by-step explanation:

x = 5

then

2x + y = 10

2 * 5 + y = 10

y = 10 - 10

y = 0

x = 5, y = 0

Hope it will help :)

Answer:

x=5

Step-by-step explanation:

so it would be 2(5) since 5 is x and that would be 10+y=10.

soo if you're trying to find what + what = 10 it would be zero.

10+0=10.

In a park for 6 people the ticket cost $39. How many dollar does it cost for 9 people

Answers

$ 58.50

Step-by-step explanation:

because 39 Divided by 6 is 6.5 and 6.5 × 9 it's 58 50

•ANSWER•
$58.50

•EXPLANATION•
The first thing you have to do is divide 39 by 6 to see how much it would cost for 1 person. For 1 person it cost $6.50 then you multiply by 9 because you are trying to figure out how much it cost for 9 people not 1. You will get $58.50.

4. Which of the following values of x is not in the domain of f (x) = log; (10-2x)?

Answers

Answer:

its choice 3) 5

Step-by-step explanation:

We want to see which of the given values of x is not in the domain of f(x) = log(10 - 2x).

The correct option is (3); x = 5.

The domain is defined as the possible inputs of a given function f(x), in this particular case, we have:

f(x) = log(10 - 2x).

Remember that the logarithmic function is only defined for positive arguments, so the values of x that are NOT in the domain of f(x), are these x values such that:

10 - 2x ≤ 0

Solving it for x we have:

10 ≤ 2x

10/2 ≤ x

5 ≤ x

So any value of x equal to or larger than 5 is not in the domain of the given functions, and of the shown options, the only one that is equal or larger than 5 is x = 5, the third option.

So the correct option is the option (3).

Write a linear function f with the values f(3)=2 and f(0)=6

Answers

Answer:

for f(3)=2 is y=(2/3)x

Step-by-step explanation:

y=ax

and plug x and y into the parent function.

Answer:

f(x) = -⁴/₃x + 6

Step-by-step explanation:

f(0) = 6 means y-intercept b = 6

So we have:

f(x) = mx + 6 and f(3) = 2

So:

2 = m×3 + 6

3m + 6 = 2

3m = 2 - 6

3m = -4

m = -⁴/₃

Therefore the function:

f(x) = -⁴/₃x + 6

If function f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.

Degree of polynomial is two so it will have only two solution

f(a)=0 if x=a

f(b)=0 if x=b

so put X=x+3

we will get

2[x+3]^2 - 3[x+3] + 4 = 2x^2 +9x +13

so if f(x+3)= 2x^2 +9x +13
