Mathematics

Answer: -3

Explanation: In this problem, we're given the function f(x) = 2x + 1 and we're asked to find f(-2).

To find f(-2) or the value of the function or the value of the function when <em>x = -2</em>, we simply substitute -2 in for <em>x</em> in our function.

So we have f(-2) = 2(-2) + 1 or -4 + 1 which equals -3.

So f(-2) or the value of the function when x = -3 is -3.

In one year, Angelica's height went from 52 inches to 56 inches what was the percent of increase in Angelica's height
AleksandrR [38]

Answer: 7.7%

Step-by-step explanation: First find the increase in height by subtracting 52 from 56. 56-52=4.

To find what percent this is of 52, divide 4 by 52. 4/52=0.0769. Then convert this from a decimal to a percent by multiplying by 100. 0.0769*100=7.69.

I just rounded it to the nearest tenth, you can change it how you need to.

What is the equation, in slope-intercept form, for the line through the point
goblinko [34]

Answer:

A perpendicular line has an opposite-reciprocal slope.

The slope given is m = 5. So the perpendicular slope is m = -\frac{1}{5}.

Now subsitute your (x, y) values to find the y-intercept, b.

y = -\frac{1}{5} x + b

-1 = -\frac{1}{5}( 3) + b

-1 = -\frac{3}{5}+ b

-1 + \frac{3}{5} = b

-\frac{5}{5} + \frac{3}{5} = b = -\frac{2}{5}

Answer: y = -\frac{1}{5} x - \frac{2}{5}

Which function has a domain of x&gt;-5?
Rom4ik [11]

Answer:

f(x)=x-5 is a linear function

Step-by-step explanation:

so there are no restrictions to what x can be. The domain is all real numbers. In interval notation, we show that is can be anything from negative infinity through infinity like this: This says that the lower limit of the domain is negative infinity and the upper limit is positive infinity.
