3x + 1/5y - 2 = 0<br>A. y=15x + 10<br>B.y=15x - 10<br>C.y=-15x +10<br>D.y=-15x-10​
Svetach [21]

Answer:

C

Step-by-step explanation:

You need to isolate the y variable. The first thing you need to do is move the 2 and 3x to the other side of the equation.

3x + 1/5y - 2 = 0

1/5y = -3x +2

Then you need to get rid of the 1/5 so you multiply both sides equation by the reciprocal of 1/5 which is 5/1 or 5.

y = ( -3x +2) 5

then you distribute the 5 to get

y = -15x+10

katrin [286]
We know that the pet Guinea gained 8 ounces in one month.

The question asks for the weight gained by Guinea in also one month.

On a road trip a family drives 350 miles per day. How many days, d, must must they travel to reach a distance of at least 1, 400
Marta_Voda [28]

Answer:

The Inequality representing the situation is 350d\geq 14000 .

Family needs to drive at least <u>40 days</u> to reach a distance of at least 1, 4000 miles.

Step-by-step explanation:

Given:

Number of miles family drive per day =350 miles

We need to find the number of days d they must travel to reach a distance of at least 1, 4000 miles.

we need to write the inequality to representing the situation.

Solution:

Let the number of days to be driven be 'd'

So now we can say that;

Number of miles family drive per day  multiplied by the number of days to be driven should be greater than or equal to 14000.

framing in equation form we get;

350d\geq 14000

Hence The Inequality representing the situation is 350d\geq 14000 .

On Solving we get;

Dividing both side by 350 we get;

\frac{350d}{350}\geq \frac{14000}{350}\\\\d\geq 40\ days

Hence Family needs to drive at least <u>40 days</u> to reach a distance of at least 1, 4000 miles.
