Answer:
100°
Step-by-step explanation:
m L 1 = (180-100) + 20 = 80+20 = 100°
Find m∠1 and m∠2. Tell which theorem can be used.
Answer:
1 = 117 ( vertically opposite angles are equal )
2 = 117 ( corresponding angles are always equal )
Step-by-step explanation:
Answer:
angle one=122 because it is using the alternate interior angle theorem
angle 2=58 because it is using the consecutive interior angle theorem
hope this helps
have a good day :)
Step-by-step explanation:
remember consecutive=same sine 122 is on the same side of angle 2 just substract 180-122=58
since 122 is on the opposite side of angle 1 it's going to be alternate something so since it's on the inside its going to be alternate interior angle
-4.3 + x equals 0 selected place on the number line to positive value of x
Answer:
x is equal to 4.3
Step-by-step explanation:
since it's -4.3 + x is equal to 0
you take -4.3 to the other side of the equal sign which makes it positive and x is equal to 4.3
Kendra spent ⅓ of her allowance on a book and ⅖ on a snack. If she had four dollars remaining after purchasing a book and snack, what was the total amount of her allowance?
Answer: 15$
Step-by-step explanation:
Given
Kendra spent one-third of allowance on a book and two-fifth on snack.
If she had four dollar remaining after purchase
Suppose x is the original amount
[tex]\therefore x-\dfrac{x}{3}-\dfrac{2x}{5}=4\\\\\Rightarrow \dfrac{15x-5x-6x}{15}=4\\\\\Rightarrow 4x=60\\\Rightarrow x=15[/tex]
Thus, 15$ was her total allowance.

Solve the simultaneous equation 4x + 3y = -2 8x + 3y = 14
Answer:
x = 4 and y = -6
Step-by-step explanation:
Solve by elimination by multiplying the first equation by -2:
-8x - 6y = 4
8x + 3y = 14
Add them together and solve for y:
-3y = 18
y = -6
Plug in -6 as y into one of the equations and solve for x:
8x + 3y = 14
8x + 3(-6) = 14
8x - 18 = 14
8x = 32
x = 4
So, the solution is x = 4 and y = -6
Answer:
x = 4
y = -6
Step-by-step explanation:
4x + 3y = -2
8x + 3y = 14
Multiply the second equation by -1
4x + 3y = -2
-8x - 3y = -14
--------------------------
-4x = -16
Divide by -4
-4x/-4 = -16/-4
x = 4
4x+3y = -2
4*4 +3y = -2
16 +3y = -2
3y = -2-16
3y = -18
y = -6
Find the sum of the first 41 terms of the following series, to the nearest integer. 4, 12,20,...
Answer:
Sum of the first 41 terms = 6724
Step-by-step explanation:
[tex]a_{41} = a_1 + (n - 1 )d = 4 + (41 - 1) \times 8= 4 + 40 \times 8 = 324\\\\S_n = \frac{n}{2}(a_1 + a_n)\\\\s_{41} = \frac{41}{2} (4 + 324) = \frac{41}{2} \times 328 = 41 \times 164 = 6724[/tex]
The sum of the first 41 terms of the following series, to the nearest integer, is 6724.
What is an arithmetic sequence?A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
Given:
An arithmetic sequence,
4, 12,20,...
The common difference d,
d = 20 - 12 = 8.
To find the sum of the first 41 terms:
We will find the 41st term.
Remember that,
aₙ= a₁ + (n-1)d
a₄₁ = 4 + (40)8
= 324
The sum of the first 41 terms,
Sₙ = (41/2)(4 + 324) = 6724.
Therefore, the sum is 6724.

Answer:
[tex]x^{\circ}+105^{\circ}=180^{\circ},\\x^{\circ}=z^{\circ},\\180^{\circ}-z^{\circ}=y^{\circ}[/tex]
Step-by-step explanation:
Statement 1:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 2:
True - These two angles are vertical angles (opposite to each other at intersection of two lines). All vertical angles are equal.
Statement 3:
False - These two angles are vertical and therefore are equal. Thus, they cannot have a difference of 105.
Statement 4:
False - Two of these angles form one side of a line which is equal to 180 degrees. Since the third angle is greater than zero, they cannot all add up to 180 degrees.
Statement 5:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 6:
False - These two angles are supplementary (add up to 180 degrees) because they form one side of a line and therefore cannot be equal to 105.
Answer and Step-by-step explanation:
The answers are:
x + 105 = 180 (Supplementary angles = 180 degrees)
x = z (Vertical angles are congruent)
180 - z = y (Supplementary angles = 180 degrees)

WILL GIVE BRAINLIEST: What is the local minimum value of the function g(x)=x^4-5x^2+4? (Round answer to the nearest hundredth)
Answer:
Step-by-step explanation:
you can find where the first derivative is 0 to find the critical points
g'(x) = ( x^4 -5x^2 +4)' = 4x³-10x
g'(x) =0, make y =0 to find find where g'(x) is 0
4x³-10x =0 , factor 2x
2x(2x²-5)= 0 , each factor must be 0
2x= 0, so x= 0
2x²-5 =0, so x = ±√5/2
we now have 3 critical points -√5/2, 0, and √5/2
make intervals (-∞, -√5/2), (-√5/2, 0) , (0, √5/2) and (√5/2, +∞)
pick a point to test on each interval: -2, -1, 1 and 2 for example, and
calculate g'(x) = 4x³-10x at those points
for x= -2 we have 4(-2)³-10(-2) = -12 , negative number, decrease
for x= -1 we have 4(-1)³-10(-1) =6, positive number, increase
for x= 1 we have 4(1)³-10(1) = -6, negative number, decrease
for x= 2 we have 4(2)³-10(2) = 12, positive number, increase
we went from a decrease to an increase on intervals (-∞, -√5/2), (-√5/2, 0) so x= - √5/2 ≈ -1.58 is a minimum
we went from a decrease to an increase on intervals (0, √5/2), (√5/2, +∞) so
x= √5/2 ≈ 1.58 is a minimum as well

Trey and Matt each have a rectangular prism. The base of Trey’s prism is 4 cm by 7 cm and has a height of 12 cm. The base of Matt’s prism is 6 cm by 10 cm and has a height of 3 cm. Whose rectangular prism will require more material to construct?
Answer:
Trey's rectangular prism will require more material to construct.
Explanation:
Trey's rectangular prism's surface area is more than Matt's rectangular prism's surface area.
Matt's prism volume is lower than Trey's prism, therefore Matt’s prism required more material to construct.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Here,
The base of Trey’s prism is 4 cm by 7 cm and has a height of 12 cm.
Volume of Trey's prism = 4 × 7 × 12 = 336 cm³
The base of Matt’s prism is 6 cm by 10 cm and has a height of 3 cm.
Volume of Matt’s prism = 6 × 10 × 3 = 180 cm³
From the above calculation, Matt’s prism required more material to construct.

Step-by-step explanation:
Okay, here it goes:
Where there is a g you insert -2 and where there is an h you insert 5
(2(-2)+9(5)-5)-(6(-2)-4(5)+2)
If two numbers are side-by-side with no other sign between them, you multiply
(-4+45-5)-(6(-2)-4(5)+2)
(-4+45-5)-(-12-20+4)
There is a subtraction sign between these equations. That means you must distribute the negative sign to the equation on the right.
Remember:
Negative × Negative = PositiveNegative × Positive = NegativePositive × Positive = Positive-4+45-5+12+20-4
Now just add them together. I recommend going left to right.

ANSWER QUICK PICTURE ATTACHED
Answer:
Step-by-step explanation:
x+5+x+7x-5=180 degree (being the interior angles of a triangle)
9x=180
x=180/9
x=20 degree
Answer:
x° = 20°
Step-by-step explanation:
Sum of angles of triangles = 180°
Therefore,
(x + 5) + (7x - 5) + x = 180
x + 5 + 7x - 5 + x = 180
9x = 180
x = 20
∠M = (x + 5) = 20 + 5 = 25°
∠L = (7x - 5) = 140 - 5 = 135°
∠N = x = 20°
