Answer:
60 degrees
Step-by-step explanation:
40 degrees + 2y+20 degrees makes a straight angle. (from alternate interior angles postulate)
Thus, 2y+60 degrees = 180, or 2y = 120 degrees.
This means y = 60 degrees

Answer: range: 3, domain: 4
Step-by-step explanation:
the range of a problem is basically the difference between the smallest and the largest y value. the largest y value here is 6 and the smallest is 3, so 6-3 = 3 -> 3 is your range! now for domain: the domain of a problem is the difference between the smallest and largest x value. the largest x value is 2 and the smallest is -2, so 2 - -2 = 4 -> the domain is 4! hope this helped!
Do the side lengths of 8, 15, and 20 form a triangle? Explain.
Can you explain how you did this
Yes; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
The side lengths 8, 15, and 20 form the sides of a .triangle
In order to determine whether the length of the sides forms a triangle, we will use the theorem that states that:
The sum of any two sides of the triangle must be greater than the thirdGiven the side lengths 8, 15 and 20
Taking the sum of any two sides;
8 + 15 = 23
Since 23 > 20 (third side), this shows that the theorem is true
Similarly;
8 + 20 = 28Since 28 > 15 (third side), this shows that the theorem is trueAlso;
15 + 20 = 35Since 35 > 8 (third side), this shows that the theorem is trueSince all the conditions are met, hence the side lengths form a triangle.

Answer:
20
Step-by-step explanation:
Write an equation for the line that is parallel to the given line and passes through the given point . Write the equation of the line in y=mx+b form
y=5x-7;(2,-2)
A parallel line has the same slope as the original equation. Therefore, the slope (m in y=mx+b) will be 5. From there, we can use the point-slope formula and convert it into the slope-intercept formula (y=mx+b).
Point-slope is:
y-y₁=m(x-x₁)
Plug in our known values:
y-(-2)=5(x-(2))
Distribute and set it equal to y:
y+2=5x-10
y=5x-12

Joseph and Wendy were catching tadpoles. At first Wendy caught nine times three more than Joseph caught. Joseph was upset and released half of Wendy 's tadpoles, and then six times as many as Joseph caught swam away. After all of this, Wendy only had three tadpoles left. How many tadpoles did Joseph catch?
Answer:
Joseph caught 7 tadpoles
Step-by-step explanation:
Let the number of tadpoles caught by Joseph be x
The number of tadpoles Wendy caught will be ;
9(x + 3)
After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;
Hence, mathematically;
9(x + 3)/2 - 6x = 3
Multiply through be 2
9(x + 3) - 12x = 6
9x + 27 -12x = 6
9x -12x = 6-27
3x = 21
x = 21/3
x = 7

Answer:
5. m∠A = 26
6. m∠D = 118
7. m∠E = 43
8. m∠H = 85
Step-by-step explanation: complementary= 90 supplementary = 180
5. (2x - 8) + (4x +4) = 90
6x - 12 = 90
6x = 102
x = 17
m∠A = 2x - 8
m∠A = 2(17) - 8 = 26
6. (2x + 18) + (5x + 8) = 180
7x + 26 = 180
7x = 154
x = 22
m∠D = 5x + 8
m∠D = 5(22) + 8 = 118
7. (2x + 15) + (3x + 5) = 90
5x + 20 = 90
5x = 70
x = 14
m∠E = 2x + 15
m∠E = 2(14) + 15 = 43
8. (5x - 20) + (4x + 7 ) = 180
9x - 27 = 180
9x = 207
x = 23
m∠H = 4x -7
m∠H = 4(23) - 7 = 85

Answer:
connor: Initial value is 200ft/ rate of change is 10
pilar: rate of change is -8/ initial value is 242
Step-by-step explanation:
so to figure out the initial value in a word problem, you need to see what it began or started with first and in the table to figure out the initial value, you need to see if there's a zero in the input and under the zero, the number in the output that's under 0 is the initial value. to find the rate of change in a word problem, if it says per, each, then it's the rate of change, Also to find the rate of change in a table you need to use this formula y²- y¹/x²-x¹ for example 234-242/1-0= -8/1 which is -8 for the slope. I hope my explanation helped. sorry if it's not clear

Aisha, Silvio, and Jim, each solved the same equation. Aisha's answer was x = 4, Silvio's answer was x = 8, and Jim's answer was x = 16. If either Aisha or Jim, but not Silvio, is correct, which of these equations could it be? Select all that apply. x3 = 64 x2 = 4 x2 = 16 x2 = 256 x2 = 64 x3 = 8
Answer:
x³ = 64x² = 16x² = 256Step-by-step explanation:
Equations and solutions
x³ = 64 ⇒ x = ∛64 = 4x² = 4 ⇒ x =√4 ⇒ x = ±2x² = 16 ⇒ x = √16 ⇒ x = ±4x² = 256 ⇒ x = √256 ⇒ x = ±16x² = 64 ⇒ x = √64 ⇒ x = ±8x³ = 8 ⇒ x = ∛8 ⇒ x= 2Aisha's answer = 4
Silvio's answer = 8
Jim's answer = 16
If either Aisha's or Jim's answer is correct then possible equations with same answers are:

A factory used 72kg of tomatoes to make 8 batches of pasta sauce .
what quantity of tomatoes did the factory put in each batch?
Given the function f(x) = - 5x² – 13x – 5,
f(20) = ???
Answer:
-2265
Step-by-step explanation:
First, we replace x with 20.
[tex]f(20)=-5*20^2-13*20-5[/tex]
Then, we evaluate.
The * stands for multiplication.
[tex]f(20)=-5*20^2-13*20-5\\-5*400-260-5\\-2000-260-5\\-2265[/tex]
[tex]f(20) = - 5 \times {20}^{2} - 13 \times 20 - 5 \\ [/tex]
[tex]f(20) = - 5 \times 400 - 260 - 5[/tex]
[tex]f(20) = - 2000 - 260 - 5[/tex]
[tex]f(20) = - 2265[/tex]

A cyclist rode at a constant speed of 21mph for 3 hours. Then she decreased her rate of speed to 17 mph for 4 hours. How far fid they cyclist ride in 7 hour
Answer: 131 miles; 21 x 3 = 63 + 17 x 4 = 68. 63 + 68 = 131 miles
Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.
What is the speed?
The magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
Here given that,
A cyclist rode at a constant speed of [tex]21[/tex]mph for [tex]3[/tex] hours. Then she decreased her rate of speed to [tex]17[/tex] mph for [tex]4[/tex] hours.
[tex]21[/tex] x [tex]3[/tex] [tex]=63 + 17 (4)[/tex]
[tex]= 131[/tex] miles
Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.
