Answer:

-3y

Step-by-step explanation:

-15(y2)4 ÷5y3y4

Rewrite the division as a fraction

-15(y2)4

5y3y4

Multiply y3 by y4 by adding the exponents

-5(y2)4

5y7

Cancel the common factor of -15 and 5

-3(y2)4

Multiply the exponents in (y2)4

-3y8

Cancel the common factor of y8 and y7

Factor y7 out of -3y8

y7(-3y)

Multiply by 1

y7(-3y)

y7 × 1

Cancel the common factor which is y7 and y7

Rewrite the expression

-3y

Divide -3y by 1

-3y

Isabelle, who is 62 inches tall, is standing beside a tree and casts a 93 inch shadow on the ground. The shadow of the tree she

Illusion [34]

Given:

Height of Isabelle = 62 inches

Shadow of Isabelle = 93 inches

Shadow of tree = 279 inches

To find:

The height of the tree.

Solution:

Let height of tree be x.

Ratio of height to shadow for Isabelle and tree are

$\dfrac{\text{Height of Isabelle}}{\text{Shadow of Isabelle}}=\dfrac{62}{93}$

$\dfrac{\text{Height of tree}}{\text{Shadow of tree}}=\dfrac{x}{279}$

The shadow of Isabelle and tree are proportional to their shadows. So, both ratios must be equal.

$\dfrac{x}{279}=\dfrac{62}{93}$

Multiply both sides by 279.

$x=\dfrac{62}{93}\times 279$

$x=62\times 3$

$x=186$

Therefore, the height of tree is 186 inches.

Convert 3x+y is greater than 4 into slope form

rosijanka [135]

If you want to write the equation of a line in the slope/intercept form, you have to write it as $y=mx+q$

In other words, you have to solve for y. So, you simply have to subtract 3x from both sides:

$y \geq -3x+4$
