Answer:
Below.
Step-by-step explanation:
a = 37 degrees ( vertical angle to 37 )
c = 180 - 37 = 143 degrees (adjacent angles add up to 180).
b = 180 - 37 - 109 = 34 degrees (angles in a triangle sum to 180 degrees).
a = 37 degrees
c = 180 - 37 = 143 degrees.
b = 180 - 37 - 109 = 34 degrees

Choose all of the ordered pairs that are solutions to the equation y = x2 + 1.
A. (-2, 5)
B. (-1,0)
7. (1, 2)
D. (2, 4)
E. (3, 10)
Answers
Answer:
A, C, E
Step-by-step explanation:
Substitute the x- coordinate of the points into the equation and if the result is equal to the y- coordinate of the point then it is a solution.
A (- 2, 5 )
y = 2² + 1 = 4 + 1 = 5 → (- 2, 5 ) is a solution
B (- 1, 0 )
y = (- 1)² + 1 = 1 + 1 = 2 ≠ 0 ← not a solution
C (1, 2 )
y = 1² + 1 = 1 + 1 = 2 → (1, 2 ) is a solution
D (2, 4 )
y = 2² + 1 = 4 + 1 = 5 ≠ 4 ← not a solution
E (3, 10 )
y = 3² + 1 = 9 + 1 = 10 → (3, 10 ) is a solution

Answer:
-16x, and 3(x−28)
Step-by-step explanation:
-8x^2+3=-16,
Multiply 2 times −8.
which should get you −16x^2−1
Subtract 1 from 2, then you have −16x^1. For any term t, t ^1=t. so then it is -16x.
−9 ^2+3x−3
Calculate 9 to the power of 2 and get 81.

Answer:
Step-by-step explanation:
1.Consider the quadratic relation y = x^2 – 6x – 16.
a) Factor this equation using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
[y = x^2 – 6x – 16 : Two numbers when multiplied = -16, but when added = -6, would be: -8 and 2. [-8+2 = -6, and -8*2 = -16] This would lead to (x+2)(x-8) as the two factors.
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
(x+2)=0; x= -2
(x-8)=0; x = 8
2. Consider the quadratic relation y = 2x^2 + 6x – 80.
a) Factor this equation by:
1. Determining the greatest common factor (GCF).
The GCF is 2: 2*(x^2 + 3x - 40)
2. Factoring the equation using common factoring.
2*(x^2 + 3x - 40): Two numbers that when multiplied = -40, but added = 3, would be 8 and -5. So we can factor:
2*(x + 8)(x - 5)
3. Factor the expression inside the brackets using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
2*(x + 8)(x - 5)
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
0 = (x + 8) and 0=(x - 5); x = -8, and x=5

transverse s at angle 135°
180° - 135° = 45°
Angle 2 is congruent to 45° because they're alternate exterior angles.
transverse t at angle 120°
180° - 120° = 60°
Angle 3 is congruent to 60° because they're alternate exterior angles.
One rule for exterior angles in triangles is that the exterior angle is equal to the sum of the two angles adjacent to the opposite angle of the exterior angle.
135° = angle 1 + 60°
angle 1 = 75°
120° = angle 1 + 45°
angle 1 = 75°
Therefore angle 1 is 75°,angle 2 is 45° and angle 3 is 60°
Answer:
m∠1 = 75° m∠2 =45° m∠3 = 60°
Step-by-step explanation:
m∠1 = 180 - { (180 - 135) + (180 - 120) }
m∠1 = 180 - { 45 + 60 }
m∠1 = 75°
The angle between 1 and 3, lets call it x, is vertically opposite to ∠2, so we must find it first to be able to get ∠2
Since a ║b
Therefore ∠x and ∠135 are co-interior angles
Therefore ∠x = 180-135
m∠x = 45°
∠2 = ∠x (Vertically opposite angles)
∠2 = 45°
Between ∠2 and ∠3 there is an angle, let's call it z.
∠z = ∠1 (Vertically opposite angles)
∠z = 75°
Since the sum of ∠2, ∠z and ∠3 = 180° (Straight angle)
Therefore m∠3 = 180 - (∠2 + ∠z)
m∠3 = 180 - (45 + 75)
m∠3 = 60°
Or in a different way
∠2 + ∠z + ∠3 = 180
45 + 75 + ∠3 = 180
120 + ∠3 = 180
∠3 = 180 - 120
∠3 = 60°

Which term of ap 30,27,24is0
Answers
Answer:
11th term is 0
Step-by-step explanation:
30, 27 , 24 ,......0
a = first term = 30
Common difference = second term - first term = 27 - 30 = -3
nth term = a+(n-1)*d
a + (n-1)d = 0
30 + (n - 1) *(-3) = 0
30 + n*(-3) -1*(-3) = 0
30 - 3n + 3 = 0
-3n + 33 = 0
-3n = -33
n = -33/-3

a is a negative odd number

Negative

Odd
Even
Answers
Answer:
even
Step-by-step explanation:
because a is not and odd number its even
The requried two words that describe A² are "Odd" and "Positive".
What are odd numbers?Odd numbers are integers that cannot be divided evenly by 2, which means they have a remainder of 1 when divided by 2. They can be represented as 2n + 1, where n is an integer. Examples of odd numbers include 1, 3, 5, 7, 9, and so on. The opposite of odd numbers are even numbers, which can be divided evenly by 2.
The square of any negative or positive number is always positive. Thus, the first two options "Negative" and "Positive" do not apply to A². As for "Even", it describes a number that is divisible by 2, while "Odd" describes a number that is not divisible by 2. Since A is an odd number, A² will also be odd, as it is the product of an odd number multiplied by itself.
Therefore, the two words that describe A² are "Odd" and "Positive".

Can you use the perpendicular bisector theorem to solve for RS?
a)yes
b)no
Answers
Reasoning:
• A bisector is a Geometric figure line or line segment that intersects a line or shape at the midpoint and divides it into 1/2 or a 1:1 ratio.
• Therefore, a perpendicular bisector is a bisector that intersects a Geometric figure at 90°.
• Because a bisector divides a figure into two equal parts, a perpendicular bisector splits a figure into two congruent parts with a 90° intersection.
• Therefore, with perpendicular bisector RT, segments UR and RS are congruent.
• So, segment UR = 17, which means that segment RS = 17 because the bisector splits it into two halves or congruent parts.
