Factor the polynomial by its greatest common monomial factor.

inna [77]

Answer:

$5 {y}^{2} (4 {y}^{4} - 3 {y}^{2} + 8)$

Step-by-step explanation:

We want to factor the common monomial out of :

$20 {y}^{6} - 15 {y}^{4} + 40 {y}^{2}$

The greatest common monomial fact is

$5 {y}^{2}$

We factor to get:

$5 {y}^{2} (4 {y}^{4} - 3 {y}^{2} + 8)$

The expression in the parenthesis has no common factor again since we factored the greatest common factor.

Two cars are 190 miles apart and travel toward each other along the same road. They meet in 2 hours. One car travels 5 miles per

horrorfan [7]

The speed of slower car is 45 mph and faster car is 50 mph.

Step-by-step explanation:

Given,

Distance covered by both cars = 190 miles

Time taken by both of them = 2 hours

Let,

x be the speed of slower car.

Speed of faster car = x+5

Combined speed = x+x+5 = 2x+5

We know that;

Distance = Speed * Time

$190=(2x+5)*2\\190=4x+10\\4x=190-10\\4x=180\\$

Dividing both sides by 4

$\frac{4x}{4}=\frac{180}{4}\\x=45$

Speed of slower car = 45 miles per hour

Speed of faster car = 45+5 = 50 miles per hour

The speed of slower car is 45 mph and faster car is 50 mph.

Give the domain and range of the relation (10,-3),(12,3),(-8,-7),(6,-1)

Iteru [2.4K]

Domain: {10, 12, -8, 6}

Range: {-3, 3, -7, -1}

There is one value of y for every value of x.

This relation is a function.
