What is the value of x in the following equation?
2 answers:
Answer:
Step-by-step explanation:
To cancel out "- 2", we add 2 into both sides.
Now, we need to get rid of 2x so we can have one x.
Let's subtract 2x from both sides.
To get x by itself, we will divide both sides by -5.
<em>The value of x in the given equation is -2. I do not see a -2 in the answer choices. </em>

The length of q, to the nearest 10th of a centimeter is 7.6 cm.
Given in question,
In ΔOPQ,
o = 9.2 cm
p = 2.4 cm
∠Q = 37°
Cosine formula ⇒ cos θ =
Putting the values in equation,
cos 37 =
0.799 =
0.799*44.16 = 90.4 -
32.28 = 90.4 -
= 90.4 - 32.28
= 58.12
q = 7.6 cm (to nearest 10th)
Hence, length of q is 7.6 cm.

Answer:
Step-by-step explanation:
A
A will give you the roots (the x intercepts) just by reading the numbers and doing a small adjustment.
x + 1 = 0
x = - 1 So one of the roots is (-1,0)
x + 5= 0
x = - 5 The other root is (-5,0)
A is not the answer.
B
I have graphed B so that you can see that A is true. See below, Even so, B is in standard form and it is not the answer.
C
The answer is C. The vertex is at 2,27
x - 2 = 0
x = 2
The maximum value is located at 27 which is just read.
That point (2,27) is plotted on the graph.
