Answer:
20 chocolates
Step-by-step explanation:
I got 20 chocolates as my answer because I multiplied the 2 chocolates eaten each day by the 8 days. She eats 2 chocolates each day for 8 days. 8x2=16. Then, I took the 36 chocolates and subtracted 16 chocolates eaten to get the answer of how many chocolates are left. 36-16=20. Therefore, Chloe has 20 chocolates.
Chloe has 20 chocolates remaining 8 days after her birthday.

Step-by-step explanation:
y = 3x + 4
Plugin x = 3 in the equation,
y = 3*3 + 4
= 9 + 4
y = 13
Plugin x = 4 in equation,
y = 3*4 + 4
= 12 + 4
y = 16
Plugin x = 5 in the equation,
y = 3*5 + 4
= 15 + 4
y = 19
2) y =x - 7
Plugin x = 10 in the equation
y = 10 - 7
y = 3
Plugin x = 15 in the equation
y = 15 - 7
y = 8
Plugin x = 20 in the equation
y = 20 - 7
y = 13

☛[tex] \underline{ \underline{ \text{question}}}[/tex] : In the given figure , O is the centre of the circle. Two equal chords AB and CD intersect each other at E. Prove that :
i. AE = CE
ii. BE = DE
*Random/irrelevant answers will not be tolerated !
Answer:
See Below.
Step-by-step explanation:
In the given figure, O is the center of the circle. Two equal chords AB and CD intersect each other at E.
We want to prove that I) AE = CE and II) BE = DE
First, we will construct two triangles by constructing segments AD and CB. This is shown in Figure 1.
Recall that congruent chords have congruent arcs. Since chords AB ≅ CD, their respective arcs are also congruent:
[tex]\stackrel{\frown}{AB }\, \cong\, \stackrel{\frown}{CD}[/tex]
Arc AB is the sum of Arcs AD and DB:
[tex]\stackrel{\frown}{AB}=\stackrel{\frown}{AD}+\stackrel{\frown}{DB}[/tex]
Likewise, Arc CD is the sum of Arcs CB and DB. So:
[tex]\stackrel{\frown}{CD}=\stackrel{\frown}{CB}+\stackrel{\frown}{DB}[/tex]
Since Arc AB ≅ Arc CD:
[tex]\stackrel{\frown}{AD}+\stackrel{\frown}{DB}=\stackrel{\frown}{CB}+\stackrel{\frown}{DB}[/tex]
Solve:
[tex]\stackrel{\frown}{AD}\, \cong\,\stackrel{\frown}{CB}[/tex]
The converse tells us that congruent arcs have congruent chords. Thus:
[tex]AD\cong CB[/tex]
Note that both ∠ADC and ∠CBA intercept the same arc Arc AC. Therefore:
[tex]\angle ADC\cong \angle CBA[/tex]
Additionally:
[tex]\angle AED\cong \angle CEB[/tex]
Since they are vertical angles.
Thus:
[tex]\Delta AED\cong \Delta CEB[/tex]
By AAS.
Then by CPCTC:
[tex]AE\cong CE\text{ and } BE\cong DE[/tex]

Write an equation for 96% of what number is 24?
Answer:
0.96 • x = 24, x = 25
Step-by-step explanation:
96% of what number is 24
Let's break this phrase down.
96% can be represented as 96/100 or 0.96
"of" indicates multiplication
"what number" is our unknown variable, x.
"is" represents our equals sign
Then we have our answer 24.
Let's put this all together.
0.96 • x = 24
To solve for this, divide both sides by 0.96.
x = 25

Alfonso scored 1818 points during his last basketball game, which was 40\%40% of the points the entire team scored. The entire team scored points.
Answer: 45 points
Step-by-step explanation:
Let the point of the entire team be represented by x.
Alfonso scored 18 points during his last basketball game, which was 40% of the points the entire team scored. This can then be represented in an equation as:
40% of x = 18
40% × x = 18
40/100 × x = 18
0.4 × x = 18
0.4x = 18
x = 18/0.4
x = 45
The team's total point is 45

Consider the equation r + 2 = 3x – 4.
a. Solve the equation using algebra.
X=
Answer:
r/6 +2 = X
Step-by-step explanation:
We want to isolate X by itself to find its value. First transpose your -4 to the other side (note that -4 will become positive)
r + 2 +4 = 3x
r + 6 = 3x
To find the X, we get rid of the 3, so divide both sides by 3
r/3 + 6/3 = x
r/3 + 2 = x
OR
(r+6)/3 = x
Both works : )
Answer:
Step-by-step explanation:
We want to solve r + 2 = 3x – 4 for x.
This means isolating x on one side. To do this, first add 4 to both sides, obtaining r + 2 + 4 =3x, or:
r + 6 = 3x
Finally, divide both sides by 3:
r + 6
x = -------------

Josephine bought 8 gallons of milk.
How many liters does that equal?
Answer:
Either 30 or 32, depending on if your teacher wants you to use exact decimals, or rounded numbers
Step-by-step explanation:
Usually people round liters to equal 4 per gallon, which would give you 32.
However, a liter is technically 3.785 liters per gallon- and this exact number would give you 30 as an awnser.
I'd say 32 is the safer awnser, unless your teacher has given you the number 3.785 decimal amount to use instead.

Compare the functions shown below:
f(x) = 7x + 3(x) = h(x) 2 sin(3x + π) − 1 Using complete sentences, explain which function has the greatest y-intercept.
Answer:
f(x) has the greatest y-intercept
Step-by-step explanation:
* Lets explain how to solve the problem
- The function f(x) = 7x + 3
- The function g(x) is tangent function with y-intercept at (0 , 2)
- h(x) = 2 sin(3x + π) - 1
* Lets explain how to find the y-intercept
- The y-intercept means the intersection of the graph of the
function with the y- axis
- Any point on the y-axis has x-coordinate = 0, so to find the y-intercept
of any function substitute x in the function by zero
∵ f(x) = 7x + 3
∵ x = 0
∴ f(x) = 3
∴ The y-intercept of f(x) is 3
∵ g(x) has y-intercept at point (0 , 2)
∴ The y-intercept of g(x) is 2
∵ h(x) = 2 sin(3x + π) - 1
∵ x = 0
∴ h(x) = 2 sin(3 × 0 + π) - 1
∴ h(x) = 2 sin(π) - 1
∵ sin(π) = 0
∴ h(x) = 2 (0) - 1 = 0 - 1 = -1
∴ The y-intercept of h(x) is -1
∵ 3 > 2 and 3 > -1
∴ f(x) has the greatest y-intercept
The function f(x) has the greatest y-intercept i.e. 3.
Given functions are:
[tex]f(x)=7x+3\\[/tex]
[tex]h(x)=2Sin(3x+\pi )-1[/tex]
What is the y-intercept?The y-intercept is the point on the y-axis at which the graph intersects.
We know that on the y-axis, the x-coordinate is zero.
So, by putting x=0 in the function we can get the y-intercept.
1)[tex]f(x)=7x+3\\[/tex]
[tex]f(0)=3[/tex]
So, the y-intercept of f(x) is 3.
2)From the graph we can say the y-intercept of g(x) is 2.
3)[tex]h(x)=2Sin(3x+\pi )-1[/tex]
[tex]h(0)=2Sin\pi -1[/tex]
[tex]h(0)=-1[/tex]
So, the y-intercept of h(x) is -1.
Hence, function f(x) has the greatest y-intercept i.e. 3.

x²+3xy−18y²
Answer:
(x + 6y)(x - 3y)
Step-by-step explanation:
Given
x² + 3xy - 18y²
Consider the factors of the coefficient of the y² term (- 18) which sum to give the coefficient of the xy- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , then
x² + 3xy - 18y² = (x + 6y)(x - 3y)
Which function represents the inverse of function fbelow?
f(x) = 3 x + 5
Answer:
[tex]f^{-1}[/tex] (x) = [tex]\frac{x-5}{3}[/tex]
Step-by-step explanation:
let y = f(x) then rearrange making x the subject , that is
y = 3x + 5 ( subtract 5 from both sides )
y - 5 = 3x ( divide both sides by 3 )
[tex]\frac{y-5}{3}[/tex] = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = [tex]\frac{x-5}{3}[/tex]
