First problem.
The function is f(x) = 3^x.
The base, b, is 3 since 3 is raised to power x.
The question is what value of x used in 3^x makes the expression 3^x equal to 3?
Look at the graph, and find the point that has y-value 3.
Which x-value does that point have?
The point is (1, 3), and the x-value is 1.

Second question.
The question is similar to the question above using a different exponential function.
(1/4)^1 = 1/4, so the answer is x = 1

While on vacation in Mexico Jeremiah reads a distance marker that indicates he is 89 kilometers from Juarez. If 1 mile is approx

Sedbober [7]

Answer:

Distance between Jeremiah and Juarez is 55.3 miles

Step-by-step explanation:

We are given

1 mile is approximately 1.61 kilometers

so,

1.61 km =1 mile

we can divide both sides by 1.61

$1km=\frac{1}{1.61}mile$

now, to find for 89 km

we can multiply both sides by 89

$89\times 1km=89\times\frac{1}{1.61}mile$

now, we can simplify it

and we get

89 km =55.2795 mile

so, nearest tenth is

89 km =55.3 mile

So,

Distance between Jeremiah and Juarez is 55.3 miles

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

Simplify. Please show your work.<br> 4a+12b+10a-4b

Drupady [299]

Answer:

14a + 8b

Step-by-step explanation:

First, you need to combine like terms.

4a + 10a = 14a

12b + (-4b) = 8b

14a + 8b
