Please Help, solve this create and solve system of equations and solve for x and y
Answer:
x = 4, y = 12
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral sum to 180° , then
25x - 2 + 7y - 2 = 180
25x + 7y - 4 = 180 ( add 4 to both sides )
25x + 7y = 184 → (1)
--------------------------
22x + 7 + 7y + 1 = 180
22x + 7y + 8 = 180 ( subtract 8 from both sides )
22x + 7y = 172 → (2)
Subtract (2) from (1) term by term to eliminate y
3x + 0 = 12
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
25(4) + 7y = 184
100 + 7y = 184
7y = 84 ( divide both sides by 7 )
y = 12

Use the distributive property to write an expression that is equivalent to 6(w - 4)
Answer:
6w-24
Step-by-step explanation:
You would distribute 6 into the parentheses, which would turn (w-4) to 6w-24
Answer:
(w - 4)6
Step-by-step explanation:
its the same exact thing but if you're looking for the simplified version then it's 6w-24
Which expressions have a value that is 8 times as much as the sum of 10 and 9? Select the correct answers.
0- 8 x (10 + 9)
1 - 8 x 10 + 9
2- 10 + 9 x 8
3- (10 + 9) x 8
4- (10 x 8) + 9
Answer:
3
Step-by-step explanation:
(10+9) = 19
19×8 =152
when you divide 152by8 you still get 19 which is the sum of 10+9

A rectangle has a height of x+ 9 and a width of x^2 + 2x
Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.
X^2
+
2x
X
+
9
Answer:
x³ + 11x² + 18x
Step-by-step explanation:
(x² + 2x)(x + 9)
Step 1: Distribute x²+2x into x + 9.
x³ + 2x² + 9x² + 18x
Step 2: Combine like terms.
x³ + 11x² + 18x
The area of this rectangle is x³ + 11x² + 18x.
Answer:
Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x
Step-by-step explanation:
The height is (x + 9) and the width is (x^2 + 2x) and the the area of the rectangle is equal to: Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x

Evaluate without a calculator:
cot -270°
Answer:
0
Step-by-step explanation:
The cotangent function is defined as cot x = adj / opp.
The terminal side of 270 degrees is the lower half of the y-axis. The adj side is zero (0) and the opp side is -1;
Therefore, cot (-270 degrees) = adj / opp = 0/(-1) = 0
The required answer is cot(-270°) is undefined
Given that cot(-270°).
To evaluate cot(-270°) without a calculator, use the trigonometric properties and definitions.
First, let's recall the definition of the cotangent function. The cotangent of an angle is defined as the ratio of the adjacent side to the opposite side in a right triangle.
cot(theta) = adjacent side / perpendicular
When we consider -θ, it represents a reflection or rotation of θ about the origin. This reflection does not affect the ratio of the adjacent side to the opposite side in a right triangle.
Thus, cot(-θ) = cot(θ).
In this case, dealing with an angle of -270°. Since angles can be measured counterclockwise, -270° represents a rotation of 270° clockwise from the positive x-axis.
At -270°, the terminal side of the angle lies on the negative y-axis.
cot(-270°) = cot(270°)
Since 360° - 270° equals 90°, cot(360° - 270°) = cot (90°)
At 90°, the terminal side of the angle lies on the positive y-axis.
In a right triangle formed with the terminal side of the angle, the adjacent side and the opposite side are both zero.
Since the cotangent is the ratio of the adjacent side to the opposite side, and both sides are zero in this case, the cotangent of -270° is undefined or "not defined."
Therefore, cot(-270°) is undefined.

A number decreased by 9 is 12. Which equation represents this situation?
Answer:
x - 9 = 12
Step-by-step explanation:
We can use x as "a number"
So the equation so far is just "a number", or x.
Decreased by 9 can also be said as subtracted by 9, so that makes the equation x - 9.
"is 12" can also be said as equals 12, which makes the equation x - 9 = 12
Answer:
_ - 9 = 12
Step-by-step explanation:
You can identify the starting number by adding 9 and 12 together to get 21. The completed equation would be 21 - 9 = 12.

Jackson is starting an exercise program.The first day he will spend 30 minute on a treadmill by 2 minutes each day.Write an equation for t(d),the time,in minutes,on the treadmill on day d
Answer:
For the d day Jackson exercised for t(d)= 30 + 2d where d is the number of day.
t(d)= 30 + 2d
Step-by-step explanation:
Let the total time on the treadmill be given by y each day and let x take the values of number of the days exercised . For the first day x= 0 and so on.
Therefore
For the first day Jackson exercised for 30 minutes
y= 30 + 2x
y= 30 + 2(0)
y= 30 minutes
For the second day Jackson exercised for (x=1) 32 minutes
y= 30 + 2x
y= 30 + 2(1)
y= 32 minutes
For the third day Jackson exercised for (x=2) 34 minutes
y= 30 + 2x
y= 30 + 2(2)
y= 34 minutes
For the fourth day Jackson exercised for (x=3) 36 minutes
y= 30 + 2x
y= 30 + 2(3)
y= 36 minutes
For the d day Jackson exercised for (x=d) 30 + 2d where d is the number of day.
y= 30 + 2x
y= 30 + 2(d)
y= 30 + 2d

solve x
8(3x+6)=9(2x−4)
Answer: -48
Step-by-step explanation:
Answer:
x=-14
Step-by-step explanation:
Expand 8(3x+6)
a=8 b=3x c=6
=8*3x+8*6
Simplify; 8*3x+8*6
=24x+48
Expand 9(2x-4)
a=9, b=2x, c=4
=9*2x-9*4
Simplify;9*2x-9*4
=18x-36
24x+48=18x-36
Subtract 48 from both sides;
24x+48-48=18x-36-48
Simplify;
24x=18x-84
Subtract 18x from both sides;
24x-18x=18x-84-18x
Simplify;
6x=-84
Divide both sides by 6;
6x/6=-84/6
Simplify; 6x/6
=x
Simplify ; -84/6
x=-14

Please help me find the answer for ABE ASAP plss!!
(Do not put links!!!)
Answer:
122
Step-by-step explanation:
The first thing to notice is that <EBC and <ABE form a straight line. This means they are a linear pair, also known as complementary. So, when they are added together they will equal 180 degrees. Therefore, to solve, set up and solve the algebraic equation, 180=58+x. When 58 is subtracted from both sides, you are left with x=122.
