Answer:

How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!

Answer:

not congruent

Step-by-step explanation:

These two triangles are not congruent because for two shapes to be congruent to each other, both needs to have same shape and size and clearly, we can see in this figure that both triangles although are the same shape, are different sizes so therefore these two triangles are not congruent. For example, the height of triangle ADE is 4 whereas the height of triangle CBA is 2.

Answer:

-1.14

Step-by-step explanation:

The given information in statement is

mean=μ=69

standard deviation=σ=3.5

Let X be the Ishaan's exam score

X=65

The Z score can be computed as

[tex]z=\frac{x-mean}{standard deviation}[/tex]

[tex]z=\frac{65-69}{3.5}[/tex]

z=-1.1429

z=-1.14 (rounded to two decimal places).

Thus, the computed z-score for Ishaan's exam grade is -1.14.

Answer:

You walked for 20 minutes and ran for 40 minutes

Step-by-step explanation:

System of Equations

Let x = the number of minutes you ran

y = the  number of minutes you walked

Walking and running takes a total of 60 minutes, thus:

[tex]x+y=60\qquad\qquad [1][/tex]

Running time is twice as much as walking time, thus:

[tex]x=2y\qquad\qquad [2][/tex]

Solve the system by substitution. Taking x from [2] and substitute in [1]:

2y+y=60

Simplifying:

3y=60

Solving:

y=60/3=20

Calculate x from [2]:

x=2*20=40

You walked for 20 minutes and ran for 40 minutes

Step-by-step explanation:

Ok, so you got:

The sum of twice a number and 5 is at most 15

Sum means we are going to add two things together, soo . .

___+___

Is at most means we are going to have:

___+___≤ ___

Twice a number  and 5= 2x(a variable)  + 5

(I'm going to use a as my variable, use whichever you like or are given)

2a + 5 ≤ __

Which will result in being greater than or equal to 15

So, your final equation would be:

2a + 5 ≤ 15

Answer:

It will take 3 days for their bird feeders to contain the same amount of bird seed

Step-by-step explanation:

Let the number of days it will take their bird feeder to contain the amount of bird seed be x

For Edith, the amount of birdseeds that will be left after x days will be;

4 1/2 - 3/4(x)

= 9/2 - 3x/4

For June, the amount of birdseeds that will remain after x days will be;

3 - 1/4(x)

= 3 - x/4

Since after x days, the amount of birdseeds will be equal;

Mathematically;

9/2 - 3x/4 = 3 - x/4

Let’s work with decimals to make things easier;

4.5 - 0.75x = 3 - 0.25x

4.5 -3 = -0.25x + 0.75x

1.5 = 0.5x

x = 1.5/0.5

x = 3

Answer:

f(-2) = 4

f(0) = 6

f(5) = 11

Step-by-step explanation:

You just need to plug in the different values of x into the equation

f(x)=x+6

When x = -2, then f(-2) = -2 + 6 = 4

When x = 0, then f(0) = 0 + 6 = 6

When x = 5, then f(5) = 5 + 6 = 11

f(5) = 11 , f(0) = 6 , f(-2) = 4

Given expression:

f(x) = x + 6

Find:

f(−2), f(0), f(5)

Computation:

f(x) = x + 6

When x = -2

f(-2) = -2 + 6

f(-2) = 4

When x = 0

f(0) = 0 + 6

f(0) = 6

When x = 5

f(5) = 5 + 6

f(5) = 11
