Answer:
The sum of x and y is 8.
Step-by-step explanation:
x+2y=10
x-2y=2
------------
2x = 12, so x = 6. Substituting 6 for x in the 2nd equation, we get:
6 - 2y = 2, or
4 = 2y, or y = 2. The solution is therefore (6, 2).
The sum of x and y is 6 + 2 = 8 (answer)
Answer:
6 + 2 = 8
Step-by-step explanation:
[tex]x + 2y = 10 \\ + \\ x - 2y = 2 \\ = \\ 2x = 12 \\ x = 6 \\ 6 + 2y = 10 \\ 2y = 4 \\ y = 2 \\ x + y = 6 + 2 = 8[/tex]

What is the equation of the line?
Answer:
y = 3
Step-by-step explanation:
what is the x for this problem??
Answer:
Let's just find the value of the unknown degree next to 35 degrees.
180 - 35 = 145 degrees
Since 145 degrees is the unknown degree next to 35 degrees, it is vertical to the x it will be the same therefore your answer is 145 degrees.

Consider a circle centered at C(0,0). If the point P(3,5) lies on the circle, then which of the following points also lies on the circle?
A. (-2,6)
B. (6,-[tex]\sqrt{5}[/tex])
C. (1,[tex]\sqrt{33}[/tex])
D. (-2[tex]\sqrt{2}[/tex],4)
Answer:
C
Step-by-step explanation:
First find the equation of the circle
the general formula for a circle (x-h)² + (y-k)² = r² where (h=0, k=0) are the coordinates of the center and r is the radius that we do not know
the distance between the center (0, 0) and the point (3,5) is the radius
distance formula d² = (x2-x1)² +(y2-y1)² where (x1=0,y1=0) and (x2=3, y2=5)
d² = (3-0)² + (5-0)² = 3² +5² = 9+ 25 = 34 =r²
(x-0)² + (y-0)² = 34 ; x²+y² =34 is the equation of the circle
Second check if any of the points are on the circle by substituting x and y with de given coordinates.
A. for (-2, 6) we have (-2)²+6² =34 so 4+36 =34 false
B. for (6, -√5) we have 6²+(-√5)² =34 so 36+5=34 false
C. for (1, √33) we have 1²+(√33)² =34 so 1+33 =34 true
D. for (-2√2, 4) we have (-2√2)²+4² =34 so 8+16=34 false
The measure of arc CD is 175°. Determine the measure of DBC.
1) 350 2) 87.5 3) 5 4) 175
Answer:
∠ DBC = 87.5°
Step-by-step explanation:
The inscribed angle DBC is half the measure of its intercepted arc, then
∠ DBC = [tex]\frac{1}{2}[/tex] CD = 0.5 × 175° = 87.5°

3 lan is buying a watch thal regularly
costs $75. It he plans to use a $15 gift
cord and sales tax is 6.4%, what will he
pay in total ?
Answer:
$63.84
Step-by-step explanation:
First, you subtract the gift card amount before taxing the new price.
75-15=60
then to calculate tax, use this equation:
.064×60=3.84
Add the tax to the price.
60+3.84=$63.84

How do you use slope to find the second point for a whole number slope?
Answer:
you use a linear equation.
Step-by-step explanation:
y=mx+b is a linear equation, b equals the y intercept (the point at which the slope touches the y line at x=0), and m equals the slope.
All you have to do is plug in your values for the equation to work.

Playing with toy alphabet blocks, Dani mixes four of the ABCDE blocks into some combination (doesn't care about the order.) Then she takes the XYZ blocks and carefully puts these into a specific order. How many different outcomes are possible for this arrangement of seven blocks?
Answer:
The total outcomes that are possible for this arrangement of seven blocks are 5C4 * 4! * 3!
Step-by-step explanation:
Given
Out of five blocks i.e ABCDE, four blocks need to be drawn.
Hence the possible ways of drawing four blocks out of total set of 5 blocks is
5C4
Now, the total number of ways of arranging these selected four blocks is 4!
The total number of ways of arranging three blocks is 3!
Hence, the total outcomes that are possible for this arrangement of seven blocks are 5C4 * 4! * 3!

Answer:
⏩14°
Step-by-step explanation:
As we can see the opposite sides are equal and the opposite angles are equal so it is a parallelogram. Hence
5x = 70° { opposite angles of a parallelogram are equal }
x = 14°
Hope it will help :)⏩❤
The value of x in the given figure is 14, Option A is correct.
We need to find the value of x in the given figure.
The opposite angles in the given figure are equal.
So when we equate both the angles we get an equation
5x=70
Divide both sides by 5
x=70/5
x=14

ABCD is a parallelogram. Which statements are true?
Answer:
Final Answer: Statements 1, 2 and 4 are correct.
Step-by-step explanation:
Finding value of y:
2y + 3 = 15 => 2y = 12 => y = 6;
Finding value of x:
6x + 5 = 77 => 6x = 72 => x = 12;
Statement Number 1:
y² > 2x ? => 6² > 2 * 12 ? => 36 > 24 ?
Yes, 36 is bigger than 24, therefore statement one is correct.
Statement 2:
x = 2y ? => 12 = 2 * 6? => 12 = 12?
Yes, 12 is equal to 12. Statement 2 is correct.
Statement 3:
x + 2 = y + 10 ? => 12 + 2 = 6 + 10? => 14 = 16?
No, 14 is not equal to 16. Statement 3 is incorrect.
Statement 4:
y + 4 > x - 4 ? => 6 + 4 > 12 - 4 ? => 10 > 8 ?
Yes, 10 is bigger than 8. Statement 4 is correct.

A= x r^2
A= x r x r
r means radius
The value of pi() is 3.14
r^2 means radius x radius
Substitute the radius for r: A= x 7^2
Square the radius: 7 x 7= 49
Area in terms of pi(): 49
Area in terms of square inches: 153.86 in^2
Divide the diameter by 2: 12 ÷ 2= 6
