You want to get this equation in slope intercept form and you have,
x+5y=10
You must first move x to the other side and get
5y=-x+10
next we isolate y by dividing by 5
y= -1/5x+2
So, the slope is -1/2 and the yintercept is positive 2.
We can now plot the first point at (0,2). To find the next point, we add the x and y values of our slope to the values for our slope intercept so our second point is (0+5,2-1) or (5,1)

Is f(x)=3x5^2x-3 an exponential function? If so, write it in the form f(x)=ab^x

Anna11 [10]

Answer:

$f(x)=\frac{3}{125} * 25^x$

Step-by-step explanation:

Given

$f(x)=3*5^{2x-3}$

Required

To determine if it is an exponential function, we have to write in form of

$f(x) = ab^x$

If we're able to do so, then the function is an exponential function.

If otherwise, then it is not

$f(x)=3*5^{2x-3}$

Apply Law of indices

$f(x)=3*\frac{5^{2x}}{5^3}$

Express 5^3 as 125

$f(x)=3*\frac{5^{2x}}{125}$

Factorize the exponent of 5

$f(x)=3*\frac{5^{(2)x}}{125}$

Express 5^2 as 25

$f(x)=3*\frac{25^x}{125}$

This can be rewritten as:

$f(x)=\frac{3}{125} * 25^x$

By comparing the above to $f(x) = ab^x$

We have that

$a = \frac{3}{125}$

$b^x = 25^x$

Since, we've be able to express the function as $f(x) = ab^x$

Then, $f(x)=3*5^{2x-3}$ is an exponential function

Eli has bought a shirt and a pair of pants for a total of 600 kr. Simin bought four of those shirts and two of those pants, and

fgiga [73]

Answer:

Step-by-step explanation:

let the price of one shirt be x and one pant be y

Eli--> x+y=600------eq1

Simin-->4x+2y=1500-----eq2

Solve both the equations

multiply eq1 x 4= 4x+4y=2400

now subtract ew2 from 1

you will get y=450 and x=150

so price of one shirt=150 kr

Answer:

Your final equation would be 192 ÷32 to get 6 as your height

Step-by-step explanation:

v=l×w×h

So if the area is 32 you could do 4×8 to get your area of 32. Take 192 and divide it by 32 to get the height.
