A pet store has 80 geckos and anole lizards altogether.

larisa86 [58]

I don’t know what your trying to find but you basically create an equation, like this
3x+5x=80
and solve which would result in x=10
so there is
30 geckos
and
50 anole lizards

Can you explain how to do this correctly?

iVinArrow [24]

8/x-7=7/2
16=7(x-7) cross multiply
16=7x-49
-7x=-49-16
-7x=-65 divides each side by -7
-7x/7=-65/7
X=65/7
Alternative form
X=92/7
Which is 1st options in your questions.

Hope this helps!

Does, this make any sense to anyone? I honestly don't understand it. I'm learning functions by the way.

<h3>Answer: t = 7</h3>

===========================================================

Explanation:

If we replace every copy of x with t, then we go from this

F(x) = 3x+5

to this

F(t) = 3t + 5

All we've done really is change the letter. We still are dealing with a variable. We're told that F(t) is equal to 26, which would allow us to replace the "F(t)" with "26" in the second equation above.

So we now have the equation 26 = 3t+5 which is the same as 3t+5 = 26

Let's solve for t

3t+5 = 26

3t = 26-5 .... subtract 5 from both sides

3t = 21

t = 21/3 .... divide both sides by 3

t = 7 is the answer

Now note that...

F(t) = 3t + 5

F(7) = 3*7 + 5 .... replace t with 7

F(7) = 21 + 5

F(7) = 26

This means we got F(t) = 26 when t = 7

It's the same as saying x = 7 leads to F(x) = 26.

This helps confirm we have the correct answer.

The sum of three numbers is 3. The first number minus the second plus the third is -3. The first minus the third is 1 more than

Rus_ich [418]

<u>Answer:</u> The first number is 2, the second number is 3 and the third number is -2

<u>Step-by-step explanation:</u>

Let the first number be 'x', the second number be 'y' and the third number be 'z'

The equations according to the question becomes:

⇒ x + y + z = 3 ....(1)

⇒ x - y + z = -3 ....(2)

⇒ x - z = 1 + y ....(3)

Rearranging equation 3:

⇒ x - y = 1 + z .....(4)

Putting in equation 2:

⇒ 1 + z + z = -3

⇒ 1 + 2z = -3

⇒ z = -2

Putting this value in equation 4 and equation 1, we get:

⇒ x - y = -1

⇒ x + y = 5

Cancelling 'y' by eliminiation method and equation becomes:

⇒ 2x = 4

⇒ x = 2

Putting value of 'x' and 'z' in equation 1:

⇒ 2 + y - 2 = 3

⇒ y = 3

Hence, the first number is 2, the second number is 3 and the third number is -2

What is the linear function equation represented by the graph?<br><br><br> f(x)=______________

Katen [24]

The linear function equation represented by the graph is $\boxed{y = - \frac{1}{2}x + 1}.$

Further explanation:

The linear equation with slope $m$ and intercept $c$ is given as follows.

$\boxed{y = mx + c}$

The formula for slope of line with points $\left( {{x_1},{y_1}} \right)$ and $\left( {{x_2},{y_2}} \right)$ can be expressed as,

$\boxed{m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}}$

Given:

Explanation:

From the graph it has been observed that the line passes through the points $\left( {0,1} \right)$ and $\left( {2,0} \right).$

The line intersect y-axis at $\left( {0,1} \right).$

Therefore, the y-intercept is 1.

The line the line passes through the points $\left( {0,1} \right)$ and $\left( {2,0} \right).$

The slope can be obtained as follows,

$\begin{aligned}m&=\frac{{0 - 1}}{{2 - 0}}\\&= \frac{{ - 1}}{2}\\\end{aligned}$

The slope of the line is $- \dfrac{1}{2}.$

Substitute $- \dfrac{1}{2}$ for m and 1 for c in equation $y = mx + c$ to obtain the equation of the line.

$y = - \dfrac{1}{2}x + 1$

The linear function equation represented by the graph is $\boxed{y = - \frac{1}{2}x + 1}.$
