Which graph represents 2x-5y< 15

1 answer:

scoray [572]4 years ago

7 0

Answer:

Step-by-step explanation:

Rewrite 2x-5y< 15 as follows: Add 5y to both sides. Then 2x < 15 + 5y.

Next, subtract 15 from both sides: 2x - 15 < 5y.

Finally, divide all terms by 5: (2/5)x - 3 < y

Now find the y-intercept of this line. Let x = 0. Then y = -3. Plot (0, -3) on graph paper. Now, starting at (0, -3), move your pencil point 5 spaces to the right and 2 spaces up. Plot this new point, (5, -1). Now draw a dashed line through both (0, -3) and (5, -1). Shade the area ABOVE this dashed line.

Y is directly proportional ( x+2)² <br> when x = 8 y= 250 <br> find y when x = 4

sladkih [1.3K]

Answer:

y=90 when x=4

Step-by-step explanation:

We are given that

$y\propto (x+2)^2$

When x=8 and y=250

We have to find the value of y when x=4

$y=k(x+2)^2$

Where k= Proportionality constant

Substitute the values

$250=k(8+2)^2$

$250=100k$

$k=\frac{250}{100}$

$k=5/2$

Now, substitute x=4 and k=5/2

Then, we get

$y=\frac{5}{2}(4+2)^2$

$y=\frac{5}{2}\times 36$

$y=90$
