What is the slope and y-intercept for the graph of the equation Y= 4/5 x - 3 ?

1 answer:

5 0

So,

The slope-intercept form is as follows:
y = mx + b

"m" is the slope, and "b" is the y-intercept. The y-intercept for this equation is (0,b).

Our equation is $y= \frac{4}{5} x-3$

That means that $\frac{4}{5}$ is the slope, and -3 is the y-intercept.

1/2x+1/3y=2

timofeeve [1]

Answer:

x=2

y=3

Step-by-step explanation:

x/2+y/3=2 so

3x/6+2y/6=12/6

then multiply by 6

3x+2y=12

equation number 2

x/3+y/2=13/6

2x/6+3y/6=13/6

multiply by 6

2x+3y=13

so the system is now

3x+2y=12

2x+3y=13

from the first equation 2y=12-3x, y=6 - 3x/2

then put y in the second equation

2x+3*(6-3x/2)=13

2x+18-9x/2=13

2x-9x/2=13-18

4x/2-9x/2=-5

-5x/2=-5

*(-1/5) *(-1/5)

x/2=1

*2 *2

x=2

so y=6-3*2/2=6-3

y=3

Can somebody solve please?

Mademuasel [1]

The answer is x=9. If you have to do inverse property on 4. Rhem combine like terms 7x and -4x. You'll get 3x=27, after that you divide 3 to both sides. As your answer x=9

Which is a stretch of an exponential decay function ?

sergiy2304 [10]

Using translation concepts, a stretch of a decay exponential function is given by:

$f(x) = 5\left(\frac{1}{5}\right)^x$

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

An exponential decay function is given by:

$y = ab^x$

In which |b| < 1.

A stretch means that the function is multiplied by a factor with absolute value greater than 1, hence the function would be given by:

$f(x) = 5\left(\frac{1}{5}\right)^x$
