You could use the Pythagorean theorem which is a squared +b squared= c squared

you know a and c
a=24
c=25

24 squared + x squared = 25 squared
576+x squared =625
subtract 576 from both sides
x squared = 49
square root x and 49
x=7
C is the answer

Solve 15 ≥ -3x or 2/5x ≥ -2. A.) {x | x ≤ -5} B.) {x | x ≥ -5} C.) {all reals}

Lapatulllka [165]

$15 \geq -3x\quad|:(-3)\qquad\vee\qquad \dfrac{2}{5}x \geq -2\quad|\cdot5\\\\\\
-5 \leq x\qquad\vee\qquad 2x \geq -10\quad|:2\\\\\\
-5 \leq x\qquad\vee\qquad x \geq -5\\\\\\x\geq -5\qquad\implies\qquad\boxed{\{x | x \geq -5\}}$

Give each answer as mixed number in simplest form

telo118 [61]

Step-by-step explanation:

$= \frac{1}{2} + ( - 5 \frac{9}{10} )$

$= \frac{1}{2} - 5 \frac{9}{10} \\$

$= \frac{1}{2} - \frac{5 \times 10 + 9}{10} \\$

$= \frac{1}{2} - \frac{59}{10} \\$

$= \frac{1}{2} \times \frac{5}{5} - \frac{59}{10} \\$

$= \frac{5}{10} - \frac{59}{10} \\$

$= \frac{5 - 59}{10} \\$

$= - \frac{54}{10} \\$

$= - \frac{27}{5} \\$

From the graph of the function, determine the domain and the range.

kiruha [24]

Hey there again! :)

This function is a piecewise function and it's different from previous question.

As you may notice, the graphs are separated and some of coordinate points are not a part of domain and range. That's why we have separate domain and range.

First, let's consider that line graph. The one that contains (-2,0) and (0,-2).

Our domain is the set of all x-values. Only (-2,0) is a closed dot. We use [ ] for closed dot and ( ) for opened dot.

Hence, the first domain is [-2,0)

Next, we find the range of line graph or line segment.

Range is the set of all y-values. Hence, the first range is (-2,0]

We are not done yet! We have to find the second domain and range, which is a curve graph.

From the curve graph, our first point starts from (0,4) and ends at (5,4)

Since (0,4) is an opened dot and (5,4) is a closed dot.

Therefore, the second domain is (0,5]

For the range, the minimum point is (3,2) and maximum point is (0,4) and (5,4). Use the y-coordinate to find range.

Hence, the second range is [2,4}

Gathering Both Domain and Range

First Domain is [-2,0)
First Range is (-2,0]
Second Domain is (0,5]
Second Range is [2,4]

Combine both domains and ranges.

Hence, the domain is [-2,0] U (0,5] and the range is (-2,0] U [2,4] or The First Choice

Let me know if you have any questions!
