y=5
x=30
Explanation: since all 3 angles of triangles are marked equal we can see that it is equilateral which means 8y=40 so y=5. Then we can find that the other triangle is an 120 30 30 triangle thus x is 30. You can also do this if you can see straight away that the big triangle is a 30-60-90 triangle and just use 90-60.

Answer:
Step-by-step explanation:
x + y = 1 -------------------(I)
5x + 3y = -3 -----------------(II)
Multiply (I) by (-5) -5x - 5y = -5
5x + 3y = -3 {Now add}
-2y = -8
y = -8/-2
y = 4
Plugin y = 4 in equation (I)
x + 4 = 1
x = 1 -4
x = -3
Solution: (-3, 4)

When x = -4, y = 2(-4)+2 = -6.

Fill in the other values of y the same way.
Answer:
(-4, -6)(-3, -4)(-2, -2)(-1, 0)(0, 2)(1, 4)(2, 6)Explanation:
y = 2x + 2
x: -4
y = 2(-4) + 2
y = -6
x: -3y = 2(-3) + 2
y = -4
x: -2y = 2(-2) + 2
y = -2
x: -1y = 2(-1) + 2
y = 0
x: 0y = 2(0) + 2
y = 2
x = 1y = 2(1) + 2
y = 4
x = 2y = 2(2) + 2
y = 6

Both x and y because it’s a 45-45-90 triangle
Answer:
x = 6√(2)x = 6√(2)y = 6√(2)Step-by-step explanation:
Sides equal opposite to equal angles are always equal -----------<1>If one angle of triangle is 90°, then it is a right triangle, can find sides with the help of Pythagoras Theorem. -----------<2>The sum of all three sides of any triangle is 180°. -----------<3>→ Given angles of triangle = 45° + 45° + 90° {from <3>}
→ x = y {because of <1>}
→ H² = P² + B² (Pythagoras Theorem) {from <2>}
→ (12)² = x² + y²
→ 144 = x² + x² [x = y]
→ 144 = 2x²
→ 144/2 = x²
→ 72 = x²
→ √(72) = x
→ 6√2 = x
→ x = y
so,
x = 6√2 = y
x = 6√(2)y = 6√(2)HOPE THIS HELPS YOU

Eliminate the parameter in the equations x =t Superscript one-half and y = t – 4. How can the rectangular equation be described? cubic linear quartic quadratic
ANSWER: A
Answers
A function assigns values. The rectangular equation can be described as cubic.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As the function of x and y is given, therefore, if we eliminate t from both the function we will get,
[tex]x=t^{\frac12}\\\\x=\sqrt t\\\\x^2=t[/tex]
Now, substitute the value of t in the function of y,
[tex]y= t-4\\y=x^2-4[/tex]
Further, the rectangular equation can be written as,
[tex]\text{Rectangular Equation} = x \times y[/tex]
[tex]= x \times (x^2-4)\\\\= x^3-4x[/tex]
Thus, the rectangular equation can be described as cubic.

Answers
Answer:
-91x² + 5x³ - 56x -15 = 0
Step-by-step explanation:
x² + 3x³ - 2x + 9 = 24 + 54x + 92x² - 2x³
x² + 3x³ - 2x + 9 - 92x² = 24 + 54x + 92x² - 2x³ - 92x²
-91x² + 3x³ - 2x + 9 + 2x³ = 24 + 54x -2x³ + 2x³
-91x² + 5x³ - 2x + 9 - 54x = 24 + 54x - 54x
-91x² + 5x³ - 56x + 9 - 24 = 24 - 24
-91x² + 5x³ - 56x -15 = 0

That night 60% of Ally's customers ordered pie, while 40% did not. Of Benny's customers, 20% ordered pie. What percent did not?
Find the probability that a customer ordered pie on Monday night.
Given that a customer ordered pie that night, what is the probability that their server was Ally? Round to the nearest whole percent.
Answers
Answer: See explanation
Step-by-step explanation:
Ally served 40% of the customers
Benny served 27%
Percentage served by Charli will be:
= 100% - (40% + 27%)
= 100% - 67%
= 33%
That night 60% of Ally's customers ordered pie, while 40% did not. Of Benny's customers, 20% ordered pie.
The percent that did not will be:
= 100% - 20%
= 80%
