the solution of inequality is
Step-by-step explanation:
We need to draw graph of the solution to inequality
First we will solve the inequality to find value of x
Solving the inequality:
Adding 7 on both sides
Divide both sides by -3 and reverse the inequality
The graph is attached in the figure below.
So, the solution of inequality is

The third one shows parallel lines cut by a transversal
Part a)
we have that
<span>√72
</span>√72-----> √(2*36)=√2*√36 is not 2*√36------> this is the error
√2*√36=√2*√6²-----> √2*(6)----> 6√2
<span>
</span><span>alternative method</span><span>
72 is equal to-------> 2</span>³*3²
therefore
√72-----> √[2³*3²]----->√ 2³*√3²-------> (2√2)*(3)-----> 6√2
Part b)<span>Estimate the square root of 72 to the nearest tenth
</span>
we know that
√2 is equal to 1.41
so
√72=6√2------> 6*1.41-----> 8.46----> 8.5
the answer Part b) is 8.5
The GCF of 20 and 84 is 4... Such a low greatest right?
Answer:
1. slope is -1 and y intercept is 2
3. slope is -2 and y intercept is -4
2. slope is -4 and y intercept is 2
4. this is not a line - it is a parabola
Step-by-step explanation:
1. -4y = 4x -8
y = -x + 2
3. 4y = -8x -16
y = -2x - 4
2. y = -4x + 2
4. y - 14 = -3x^2 -16x
y = 3x^2 - 16x + 4
