AD is the angle bisector of EAB. Solve for X
Answer:
A) 5.76
Step-by-step explanation:
By angle bisector property of a triangle, we have:
[tex] \frac{12}{10} = \frac{x}{4.8} \\ \\ \frac{12 \times 4.8}{10} = x \\ \\ x = \frac{57.6}{10} \\ \\ x = 5.76[/tex]
Which phrase best describes the translation from the graph y = 2x^2 to the graph of y= 2x^2 + 5?
O5 units up
O5 units down
O 5units right
O5 units left
Answer:
05 units up and down
Step-by-step explanation:
hope this hepled luv!
The phrase that best describes the translation from the graph y = 2x^2 to the graph of y = 2x^2 + 5 is "5 units up".
What is transformation on the graphs?Let the functions f(x) and g(x) be two real functions.
And g (x) = f (x) + k, where k is real numbers.
The function can be sketched by shifting f (x), k units vertically.
The direction of shift can be found by the value of k:
if k > 0, the base graph shifts k units up, and
if k < 0, the base graph shifts k units down.
Adding a constant term to a function vertically shifts its graph up or down, depending on the sign of the constant.
In this case, the constant term is positive (+5), which means that the graph of y = 2x² + 5 is shifted upward by 5 units compared to the graph of y = 2x².
Therefore, the correct phrase is "5 units up".

There are 50 students in a class. If 14% are absent on a particular day, find the number of students present in the class. What percent were not absent?
Answer:
i THINK 43% but im not for sure
Step-by-step explanation:
14% of 50 is 7
so 50-7=43
43(percent there)+7(percent gone)=50 (number of students)
SO 43% is still there.

Solve for x and all the missing angles.
(-11+3y)
(34+Y)
(37+y)°
Answer:
y=24; Angle 1: 61 degrees; Angle 2: 58 degrees; Angle 3: 61 degrees
Step-by-step explanation:
-11+3y+34+y+37+y=180 The sum of all the angles in a triangle is 180 degrees.
60+5y=180 Combine like terms
5y=120 Subtract 60 from 180
y=24 Divide 120/5
Angle 1: -11+ 3(24)= 61 degrees
Angle 2: 34+24=58 degrees
Angle 3: 37 + 24= 61 degrees

the value of a second hand car is £8000. Each year it loses 20% of its value at the start of this year. work out its value in 5 year time.
pls show working out who ever answer first get marked brainest and get rated excellent. urgently needed. need asap my teacher waiting
Answer:
0
Step-by-step explanation:
20 percent of 8000 = 1600
1600 x 5= 8000
8000 - 8000 = 0

Complete the proof!!!
Answer:
The correct options are;
1. Definition of supplementary angles
2. m∠1 + m∠2 = m∠1 + m∠3
3. m∠2 = m∠3
4. Definition of congruent angles
Step-by-step explanation:
The two column proof is presented as follows;
Statement [tex]{}[/tex] Reason
1. ∠1 and ∠2 are supplementary [tex]{}[/tex] Given
∠1 and ∠3 are supplementary [tex]{}[/tex]
2. m∠1 + m∠2 = 180° [tex]{}[/tex] (1) Definition of supplementary angles
m∠1 + m∠3 = 180°
3. (2) m∠1 + m∠2 = m∠1 + m∠3 [tex]{}[/tex] Transitive Property
4. (3) m∠2 = m∠3 [tex]{}[/tex] Subtraction property of equality
5. ∠2 ≅ ∠3 [tex]{}[/tex] (4) Definition of congruent angles
Given that angles ∠1 and ∠2 are supplementary, we have, ∠1 + ∠2 = 180°
Given that angles ∠1 and ∠3 are also supplementary, we also have, ∠1 + ∠3 = 180°
∴ ∠1 + ∠2 = 180° = ∠1 + ∠3
∠1 + ∠2 = ∠1 + ∠3
∠1 + ∠2 - ∠1 = ∠1 + ∠3 - ∠1
∴ ∠2 = ∠3
∴ ∠2 ≅ ∠3, by definition of congruent angles.
Find the value of x please
Step-by-step explanation:
In isoceles triangle two sides are equal and two angles are equal.
Then,
∠R = ∠T = (5x-40)°
Then,
∠RTS + ∠STU = 180° (bcoz it lies on a straight line)
(5x-40) ° + 5x = 180°
10x = 220°
x = 22°

Answer:
For the second question, 4 busses and 3 cars.
Step-by-step explanation:
It's really simple actually, but sorry I can't come up with an equation. You can just add or multiply students per bus and students per car until you get to 195. Each bus can hold 45 students, so 45 x 4 = 180. Each car can hold 5 students, so 5 x 3 = 15. In total, 15 + 180 = 195 students.

Each year it loses 20% of it value at the start of this year. work out its value in 5 years time.
pls show working out
I will mark brainest and rate 5 stars
Answer:
£2,621.44
Step-by-step explanation:
Original cost of car = £8000
If it looses 20% of its value yearly
Value at the end of first year
80% * 8000
= 0.8 * 8000
= 6400
Value at the end of second year
80% * 6400
= 0.8 * 6400
= 5120
Value at the end of third year
80% * 5120
= 0.8 * 5120
= 4096
Value at the end of fourth year
80% * 4096
= 0.8 * 4096
= 3,276.8
Value at the end of fifth year
80% * 3,276.8
= 0.8 * 3,276.8
= 2,621.44
Hence the value in 5 years time will be £2,621.44

Find the slope between the two points.
(2,7) and (5, 8 )
Answer:
Slope
0.33
Step-by-step explanation:
Solve each equation mentally for x.
5/2 • x = 1
Your answer must be in the form of a fraction.
You need to get x by itself to solve
So to get rid of 5/2, you need to multiply both sides by the reciprocal or 2/5...
5/2*2/5 = 1 which we don't write and 1*2/5 = 2/5
So now you'd have x =2/5
