Answer:

The value of f(-2) is 0.56

Step-by-step explanation:

Given the function

f(x)=5.3^x

we have to find the value of f(-2)

f(x)=5.3^x

Put x=-2

f(-2)=5.3^{-2}

f(-2)=5\times \frac{1}{3^2}

f(-2)=\frac{5}{9}=0.5555...\sim 0.56

Hence, the value of f(-2) is 0.56

Hello!

You put -2 in for x

I don't know whether it is times x or to the power of x so I will do both

5 * 3 * x

5 * 3 * -2 = -30
------------------------------------------------------------------------------------------------------
5 * 3^x

5 * 3^-2

5 * 1/81 = 5/9 or 0.55555

Hope this helps!

A line passes through the points (–1, –5) and (4, 5). The point (a, 1) is also on the line.
IgorC [24]

Answer:

a = 2

Step-by-step explanation:

Let's find the equation of the line using the 2 points given.

Let's call -1 as x_1 and -5 as y_1

also, 4 as x_2 and 5 as y_2

The equation of line is :

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

<em>Let's plug the points and get the equation of the line:</em>

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\y+5=\frac{5+5}{4+1}(x+1)\\y+5=2(x+1)\\y+5=2x+2\\y=2x-3

Now, to find a, we substitute a in x and 1 in y of the equation of the line we just got:

y=2x-3\\1=2(a)-3\\1=2a-3\\2a=4\\a=\frac{4}{2}=2
