Answer:

y = 3

Step-by-step explanation:

Solve for y:

y + 3 = 9 - y

Add y to both sides:

y + y + 3 = (y - y) + 9

y - y = 0:

y + y + 3 = 9

y + y = 2 y:

2 y + 3 = 9

Subtract 3 from both sides:

2 y + (3 - 3) = 9 - 3

3 - 3 = 0:

2 y = 9 - 3

9 - 3 = 6:

2 y = 6

Divide both sides of 2 y = 6 by 2:

(2 y)/2 = 6/2

2/2 = 1:

y = 6/2

The gcd of 6 and 2 is 2, so 6/2 = (2×3)/(2×1) = 2/2×3 = 3:

Answer:

y=3

Step-by-step explanation:

y+3=-y+9

(3)+3=-(3)+9

3+3=6

-3+9=6

6=6

So the answer will be B or y=3

Parsons Bank offers two checking-account plans. The No Frills plan charges

7nadin3 [17]

If the number of checks are greater than 25, the Simple Checking plan cost less.

We have two checking account plans at Parson's bank.

We have to determine for what number of checks per month will the Simple Checking plan cost less.

<h3>What is an Inequality in Mathematics ?</h3>

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Let for x number of checks per month the simple checking plan cost less.

For No frills plan -

Charge per check - $0.25

Therefore, for x checks, it will cost - $0.25x

For Simple Checking plan -

Fixed monthly charges - $5

Charges per check - $0.50

Therefore - for x checks - $5 + $0.50x

Now - for Simple Checking plan to cost less than No frills plan -

5 + 0.05x < 0.25x

5 < 0.25x - 0.05x

5 < 0.2x

x > 25

Hence, if the number of checks are greater than 25, the Simple Checking plan cost less.

If m ≤ f(x) ≤ M for a ≤ x ≤ b, where m is the absolute minimum and M is the absolute maximum of f on the interval [a, b], then

agasfer [191]

Answer:

smaller value is 1.2

larger value is 6

Step-by-step explanation:

$f(x)=\frac{3}{1+x^{2} }$

when x=a=0, one has

$f(0)=\frac{3}{1+0^{2} } \\f(0)=3$

now, when x=b=2, one has

$f(2)=\frac{3}{1+2^{2} } \\f(2)=\frac{3}{5}$

Therefore, the absolute minumun is

$m=\frac{3}{5}$

and the absolute maximun is

$M=3$

The approximation to the integral is

$\frac{3}{5}(2-0)\leq \int\limits^2_0 {f(x)} \, dx \leq 3(2-0)$

hence

$\frac{3}{5}(2)\leq \int\limits^2_0 {f(x)} \, dx \leq 3(2)\\\frac{6}{5} \leq \int\limits^2_0 {f(x)} \, dx \leq 6\\1.2 \leq \int\limits^2_0 {f(x)} \, dx \leq 6$

Help is needed!!! please

Ede4ka [16]

Answer:

Step-by-step explanation:

There are 2 ways to look at this. I will explain both.

First we have the 3-4-5 triangle method, stating that any triangle with sides 3 and 4 will have the last side as 5.

Now, for the more complex way of doing this, we can use the Pythagorean theorem to solve this problem.

Pythagorean theorem: $a^2+b^2=c^2$

We can use 4 for a and 3 for b

You will now have

$4^2+3^2=c^2\\\\16+9=c^2\\25=c^2$

Then take √25, or 5.
