You are given the domain and range ( the numbers in each oval):

If There is more than one arrow connected to a number, that number is listed the same amount

Domain (-4,0,6,6)

Range (12,18,18,40)

To be a function each input value ( Domain) can only have one output value (range)

Because the 6 has two different outputs ( 12, 18) this is not a function.

Answer:

The input 6 (domain) leads to two outputs thus it is not a function.

Does the point (0,4) make either equations y=-2x and y=x+3 true? Explain.

Nikolay [14]

Answer:

Neither

Step-by-step explanation:

To verify, we substitute the values in the equations:

$y = -2x\\y = -2 \times 0\\y = 0$

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

$y = x+3\\y= 0+3\\y = 3$

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

A man borrowed $3700 from a bank for 6 months. A friend was co-signer of the mans personal note. The bank collected 8.5% simple

Tpy6a [65]

Answer:

(A) $157.25

(B) $3,857.25

Step-by-step explanation:

The given values are:

Principle (P)

= $3700

Time (T)

= 6 months i.e., 1/2 years

Rate (R)

= 8.5%

(A)

As we know,

Simple Interest,

⇒ $SI=\frac{P\times R\times T}{100}$

On putting the values, we get

⇒ $=\frac{3700\times 8.5\times \frac{1}{2} }{100}$

⇒ $=\frac{15,725}{100}$

⇒ $=157.25$ ($) (he paid for the use of money)

(B)

Amount he paid to the bank will be:

⇒ $P+SI$

⇒ $3700+157.25$

⇒ $3,857.25$ ($)

-8z+(4.5)+3.5z+7y-1.5

bogdanovich [222]

Answer:

$\boxed{\sf{7y+3-4.5z}}$

Step-by-step explanation:

In order to combine like terms, you have to isolate x and y from one side of the equation.

$\sf{-8z+\left(4.5\right)+3.5z+7y-1.5}$

First, thing you do is remove parentheses.

$\Longrightarrow: \sf{-8z+4.5+3.5z+7y-1.5}$

Solve.

Then, you combine like terms.

$\Longrightarrow:\sf{-8z+3.5z+7y+4.5-1.5}$

Add/subtract the numbers from left to right.

-8z+3.5z=-4.5z

Rewrite the problem down.

$\Longrightarrow: \sf{-4.5z+7y+4.5-1.5}$

Solve.

4.5-1.5=3

$\Longrightarrow: \boxed{\sf{7y+3-4.5z}}$

Therefore, the correct answer is 7y+3-4.5z.

I hope this helps, let me know if you have any questions.
