Which is an equation of the line with a slope of 2/3 passing through the point (4,-1)?

Bond [772]

Answer:

y=2/3x-11/3

Step-by-step explanation:

to find the y intercept, you can input your values into the equation:

b=y1−m⋅x1

When you do that, you get:

b=−1−(2/3)⋅(4)=−11/3

When you convert that equation into y=mx+b form, you get:

y=2/3x-11/3

The depth of a lake in cedar burg changes over time due to rain fall and evaporation this year it was 39 feet which is 25% less

Nostrana [21]

Answer:

The depth of the lake last year was 52 feet

Step-by-step explanation:

Given as :

This year depth of lake = 39 feet

Let the last year depth of lake = x feet

Now,

According to question :

The depth this year is 25% less than that of last year

I.e 39 feet = x - 25% of x

Or, 39 feet = $\frac{75x}{100}$

or, x = $\frac{3900}{75}$

∴ x = 52 feet

Hence The depth of the lake last year was 52 feet Answer

Use the graph of a translated function below to answer this question

Talja [164]

The graph of the function $y=x^3$ has the point of inflection at the origin. From the diagram you can the that the graph $y=f(x - h) + k$ has the point of inflection at point (-2,-3). So you should translate the graph of the function $y=x^3$ 2 units to the left and 3 units down. This translation is acting on function $y=f(x)$ in the following way:
