one solution of x^2 - 64 = 0 is 8. what is the other solution
Answer:
- 8
Step-by-step explanation:
Given
x² - 64 = 0 ( add 64 to both sides )
x² = 64 ( take the square root of both sides )
x = ± [tex]\sqrt{64}[/tex] = ± 8
Solutions are x = 8 and x = - 8
I need help!!!! Please
the answer is
y≥2x/5+2
Step-by-step explanation:
we moved the y to the right site and the -10 to the left site
so we had
2x+10≤5y
and then we devided by 5
2x/5+10/5≤y
y≥2x/5+2
hopefully its correct
Answer: Choice D
[tex]y \ge \frac{2}{5}x +2\\\\[/tex]
=======================================
Work Shown:
[tex]2x - 5y \le -10\\\\-5y \le -2x-10\\\\y \ge \frac{-2x-10}{-5} \ \text{ ... see note1 below}\\\\y \ge \frac{-2x}{-5} - \frac{10}{-5}\\\\y \ge \frac{2}{5}x +2 \ \text{ ... answer is choice D}\\\\[/tex]
Note1: when dividing both sides by a negative number, the inequality sign flips.
----------------
Here's another approach that doesn't involve dividing both sides by a negative number.
[tex]2x - 5y \le -10\\\\2x \le -10+5y\\\\2x +10\le 5y\\\\5y \ge 2x+10 \ \text{ .... see note2 below}\\\\y \ge \frac{2x+10}{5}\\\\y \ge \frac{2x}{5} + \frac{10}{5}\\\\y \ge \frac{2}{5}x +2\\\\[/tex]
Note2: I swapped the left and right sides. Doing this swap means that the inequality sign must flip as well.
Solve for x, given: x2−4x+29=0
Answer:
X= 5i-2, x=5i-2
Step-by-step explanation:
Step-by-step explanation:
[tex] {x}^{2} - 4x + 29 = 0 \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{4± \sqrt{ - 100} }{2} \\ x = \frac{4±10i}{2} \\ x = 2±5i \\ x = 2 + 5i \: \: or \: \: x = 2 - 5i[/tex]
trig///HELPP PLEASE!! i’ve been stuck on this for 30 minutes!!
Answer: There are two solutions and they are
theta = 135
theta = 225
=============================================================
Explanation:
Recall that x = cos(theta). Since the given cosine value is negative, this indicates x < 0. Theta is somewhere to the left of the y axis, placing it in quadrant 2 or quadrant 3.
It turns out there are two solutions, with one solution per quadrant mentioned above. Use the unit circle to find that the two solutions are:
theta = 135
theta = 225
You're looking for points on the unit circle that have x coordinate equal to x = -sqrt(2)/2. Those two points correspond to the angles of 135 and 225, which are in quadrants 2 and 3 respectively.
--------
I recommend using your calculator to note that
-sqrt(2)/2 = -0.70710678
cos(135) = -0.70710678
cos(225) = -0.70710678
The decimal values are approximate. Make sure your calculator is in degree mode. Because those three results are the same decimal approximation, this indicates that cos(135) = cos(225) = -sqrt(2)/2.

Answer:
(-9/2t + 3) +( 7/4t + 33) = -11/4t + 36
5(2t + 1)+(-7t +28) = 3t+ 33
Step-by-step explanation
Those are the ones i could solve hope this helps!
1. Problem
(-9/2t + 3) +( 7/4t + 33)
-9/2t + 7/4t
-18/4t +7/4t= -11/4t
3+ 33= 36
-11/4t + 36
2. Problem
5(2t + 1)+(-7t +28)
10t + 5 + ( -7t +28)
10t - 7t= 3t
5+ 38= 33
What is the first step in solving the following equation?
28 = -12 - 4x
Answer:
4x = - 12 - 28Step-by-step explanation:
When we transpose - 4x to the LHS then it becomes positive i.e +4x
Now we transpose 28 to the RHS then it becomes negative i.e - 28
So the first step you have to is,
4x = - 12 - 28
Two right triangles are similar and have areas of 36 m and 144 m². If the hypotenuse of the larger
triangle is 30 m long, what is the length of the hypotenuse of the smaller triangle?
Answer: 18
Step-by-step explanation:
Find the scale factor: 144/36= 4. But scale factor of area is r^2=4=> r= 2
Hypotenuse of small triangle is:
36/x=2 => x=18

Half of the text is covered...
Answer:
Good Luck!
Step-by-step explanation:
You would add 16 to both side in the attempt of completing the square
Step 1: Move any constant number (this case, it's 35) to the other side
Step 2: You will have a format of ax2 + bx = c, where your a = 1, b = 8, and c = 35
*a must always be 1*
Step 3: Divide b by 2 and then square that number. Your b = 8, so 8/2 is 4. Squaring 4 gives you 16.
Hence, that's why you add 16 to both side from your question.

OPTIONS: 75 degrees, 30, 90, or 45
Answer:
x = 45
Step-by-step explanation:
x + 45 + 2x = 180
3x + 45 = 180
3x = 135
x = 45
Answer:
x = 45
Step-by-step explanation:
We know that the three angles of a triangle add up to 180. So we can add all the points equal to 180 to find the value of x.
a + b + c = 180
45 + x + 2x = 180
Combine terms.
45 + 3x = 180
Subtract 45 from both sides.
3x = 135
Divide both sides by 3 to get
x = 45.
To prove this, put x into the original addition of the angles.
45 + x + 2x = 180
Substitute 45 into x.
45 + 45 + 2(45) = 180
Multiply 2 and 45.
45 + 45 + 90 = 180
Add terms.
180 = 180.

Suppose you work at a local radio station. You are in charge of a $180 budget for
new tapes and CDs. Record companies will give you 21 promotional (free) CDs. You
can then buy tapes for $8 and CDs for $12.
a. Write a linear inequality that models this situation.
Answer
b. Graph the inequality. Make sure to use proper scales and to label your axes
Answer:
0---22.5 and 21---36
Step-by-step explanation:
you will always have 21 free CDs so you can put a closed circle on 21 then you can have a max of 15 CDs (180/12) soo put another closed circle on 36
now time for tapes, which is easier, the minimum is 0 and the max is 22.5. Now put closed circles on each and you're done. Except that .5 might get you in trouble, use your own discretion on rather to leave it on the .5 or round. I don't know what your teacher is looking for so I will let you decide.

Two numbers have a sum of 18, and 4 times the first number minus the second number is equal to 17. What is the smallest number?
Answer:
The smallest number is 7
Step-by-step explanation:
Using simultaneous equation;
x+y = 18.....(1)
4x-y = 17.....(2)
from equation (1)..
x+y = 18
y = 18-x...(3)
substitute y into equation (2)
4x-y = 17
4x-(18-x) = 17
4x-18+x = 17
4x+x = 17+18
5x = 35
x = 35÷5
x = 7
substitute x into equation (3)
y = 18-x
y = 18-7
y = 11
Therefore; x=7
y=11
11+7=18
(4×7)-11=17
the smallest number is 7

A trapezoid has an area of 140 square centimeters with bases of 12 and 10 centimeters. What is the length of the height? Round to the nearest tenth place.
Answer:
12.7 cm
Step-by-step explanation:
Area of a trapezium = 1/2 x ( a + b) x height
a and b represents the bases
140 = 1/2 x (12 + 10) x h
140 = 11h
h = 140 / 11
h = 12.727 cm
h = 12.7 cm to the nearest tenth
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
