Each property is mentioned with the corresponding expression.
Step-by-step explanation:
Writing the property in front of every expression:
1. Additive Identity: 11+0 = 11
2. Associative Property of Multiplication: x*(y*z) = (x*y)*z
3. Additive Identity: 8+(-8) = 0
4. Commutative property of Addition: 14+20=20+14
5. Multiplicative Inverse: 2*1/2 = 1
6. Multiplicative Identity : 22*1 = 22
7. Associative Property of Addition: (19+12)+8=19+(12+8)
8. Commutative Property of Multiplication: a*9=9*a
9. Distributive Property: 7(4+11) = 7(4)+7(11)
What is the mDEF? plz help
Answer:
m∠DEF = 148°
Step-by-step explanation:
The total sum of angles inside a triangle is 180°
m∠FDE + m∠EFD + m∠DEF = 180°
We can also see that because two sides are congruent, their angles are also congruent, so we can solve for x
m∠FDE = m∠EFD
2x + 8 = 3x + 4; subtract 2x from both sides
8 = x + 4; subtract 4 from both sides
x = 4; now we can substitute into equations
m∠FDE = m∠EFD;
2(4) + 8 = 3(4) + 4
8 + 8 = 12 + 4; 16=16; therefore = m∠FDE = m∠EFD = 16
To solve for m∠DEF
m∠FDE + m∠EFD + m∠DEF = 180°
16 + 16 + m∠DEF = 180
m∠DEF = 148°
Write the equation of the line y=(5)/(6)x+(7)/(6) perpendicular to
that passes through the point (-8,7)
Answer:
6x + 5y + 13 = 0.
Step-by-step explanation:
y = 5/6x + 7/6
Gradient = 5/6
Since the line is perpendicular to y = 5/6x + 7/6
then its gradient is -6/5.
Hence its equation is: point (-8,7).
y - 7 = -6/5(x -(-8))
multiplying through by 5 we get;
5y - 35 = -6(x + 8)
5y - 35 = -6x - 48
6x + 5y + 13 = 0

Mrs. Delgado said that 21 out of 25 students passed the test. What percent did NOT pass the test?
Answer:
16% of the students did not pass the test.
Step-by-step explanation:
Since 25 is 1/4 of 100, multiply it by 4 to equal 100.
Now multiply the percentage passed by 4. This equals 84.
84 out of 100 = 84%
So, the rest of the students(the ones who did not pass) is 16% of the class.

Answer:
b. The total sum of the money was $330
Step-by-step explanation:
#b
∵ A sum of money is divided among John, Paul, and Robert
∵ The ratio of the shares of John, Paul, and Robert is 2: 4: 5
→ Multiply the ratio of each share by x
∴ The share of John = 2x
∴ The share of Paul = 4x
∴ The share of Robert = 5x
→ Find their sum
∴ The sum of the money = 2x + 4x + 5x = 11x
∵ The sum of the money is divided equally among them
→ That means dividing the sum by 3 to find the share of every one
∵ The sum of the money = 11x
∴ The share of every one = [tex]\frac{11x}{3}[/tex] = [tex]\frac{11}{3}[/tex]x
∴ The share of John is larger by $50
→ That means the difference between his shares is 50
∵ [tex]\frac{11}{3}[/tex]x - 2x = 50
∴ [tex]\frac{5}{3}[/tex]x = 50
→ Divide both sides by [tex]\frac{5}{3}[/tex]
∴ x = 30
→ Substitute it in the sum of the money to find it
∵ The sum of the money = 11(30)
∴ The sum of the money = $330
∴ The total sum of the money is $330
if x=-7 is a root of the equation x^2+kx+49=0, then k=
Answer:
[tex]k=14[/tex]
Step-by-step explanation:
Given:
[tex]x^{2}+kx+49 = 0[/tex]
[tex]x = -7[/tex]
Substitution can be used to find the value of [tex]k[/tex]:
[tex](-7)^{2}+(-7)k+49 = 0[/tex]
[tex]49-7k+49 = 0[/tex]
[tex]98 -7k = 0[/tex]
[tex]k = 14[/tex]

Bisect means that the angles are split equally.
RTV would be half of RTS
RTV = 1/2(RTS)
16x-6 = 1/2(26x+18)
Simplify:
16x - 6 = 13x +9
Subtract 13x from both sides:
3x - 6 = 9
Add 6 to both sides:
3x = 15
Divide both sides by 3:
x = 5
Now you have x, replace x in the equation for RTV:
RTV = 16x -6 = 16(5) -6 = 80 - 6 = 74
RTV = 74 degrees.

Allister, who is 5 feet tall, is standing three feet from a mirror lying on the ground. When he looks into the mirror, he can just see the top of a tree that is 24 feet away from the mirror. Make a sketch of this situation, and use it to calculate the height of the tree
Answer:
40 feets
Step-by-step explanation:
Given that :
Observer's height = 5 feets
Observer's distance from the mirror = 3 feets
Distance of tree away from the mirror = 24 feets
To obtain the height of tree:
Observer's distance (Od) / tree distance (Td) = Observer's height(Oh) / tree height (Th)
Od / Td = Oh / Th
3 / 24 = 5 / Th
3 * Th = 24 * 5
Th = 120 / 3
Th = 40 feets
Hence, the height of tree is 40 feets

A. 11
B. 13
C. 17
D. 19
HURRY ANSWER IT

What is the slope of y = -42 - 3?
Is X +3 a factor of 2X squared minus 2X -12
Answer: No, x+3 is not a factor of 2x^2-2x-12
========================================================
Explanation:
Let p(x) = 2x^2 - 2x - 12
If we divide p(x) over (x-k), then the remainder is p(k). I'm using the remainder theorem. A special case of the remainder theorem is that if p(k) = 0, then x-k is a factor of p(x).
Compare x+3 = x-(-3) to x-k to find that k = -3.
Plug x = -3 into the function
p(x) = 2x^2 - 2x - 12
p(-3) = 2(-3)^2 - 2(-3) - 12
p(-3) = 12
We don't get 0 as a result so x+3 is not a factor of p(x) = 2x^2 - 2x - 12
----------------------------------------
Let's see what happens when we factor p(x)
2x^2 - 2x - 12
2(x^2 - x - 6)
2(x - 3)(x + 2)
The factors here are 2, x-3 and x+2
