Rs^4 or in words, rs to the power of 4
Y+4<u><</u>9
subtract 4
y<u><</u>5
y is smaller than and equal to 5
so you shade from 5 to the negative end to infinity (to the left) and shade the 5 to show that it is included (attachment says A)
6 less than (-6) 2 times a number (2 time x) is greater than (>) 8 (8)
-6+2x>8
add 6
2x>14
divide 2
x>7
so
x is bigger than 7
shade from 7 to the positive end to infinity (to the right) and don't shade 7 but put a circle around it to show that it is not included (attachment says B )
I have included pictures of the number lines

Answer:</h2>
<u>x= 7</u>.
<h2>
Step-by-step explanation:</h2>
<h3>1. Write the expression.</h3>
<h3>2. Take the square root of both sides of the equation.</h3>
<h3>3. Sum 3 to both sides of the equation.</h3>
<h3>4. Divide by 4 on both sides of the equation.</h3>
<h3>5. Express your result.</h3>
<u>x= 7</u>.
-3 and 1/3 would be the correct answer. Rise/run. If you count, since its on a graph, one of them is 2/6 which reduces down to 1/3 positive slope. Then the other is -3/1 which reduces down to -3 slope.
