Answer:
k = 5/6
Step-by-step explanation:
The √ can be rewrite as a power, and this power is 1/2
So √a = a^1/2, and it is multiplying a, so we add the powers: a¹•a^1/2 = a^(1+1/2) = a^3/2
And the ³√ can be rewrite as the power 1/3, but the a inside the ³√ is to the power of 2, so we can rewrite it like this: (a²)^1/3
And to evaluate this we have to multiply the powers, so we will have: a^2/3
Now we have this fraction:
[tex] \frac{ {a}^{ \frac{3}{2} } }{ {a}^{ \frac{2}{3} } } [/tex]
A fraction with powers in the same base can be rewrite like a subtraction of the powers, so let's do that:
[tex] \frac{ {a}^{ \frac{3}{2} } }{ {a}^{ \frac{2}{3} } } = {a}^{ \frac{3}{2} - \frac{2}{3} } = {a}^{ \frac{5}{6} } [/tex]

Answer:
BC = 22
Step-by-step explanation:
BD = 67
Bc = 3x - 2
CD = 4x + 13
BC + CD = BD (Given)
3x - 2 + 4x + 13 = 67
3x + 4x -2 + 13 = 67
7x + 11 = 67
7x = 67 - 11
7x = 56
x = 56 ÷ 7
x = 8
now instead of x put 8
Bc = 3x - 2
BC = 3(8) -2
BC = 24 -2
BC = 22

Equation = x2-2x-3=0
Answer:
x^2 - 2x - 15 = 0.
Step-by-step explanation:
x^2 - 2x - 3 = 0
(x - 3)(x + 1) = 0
So alpha and beta are -1 and 3.
So the roots of the required equation are 2(-1)-1 and 2(3) - 1
= -3, 5.
So the equation is
(x - 5)(x + 3) = 0
-that is x^2 - 2x - 15 = 0

A triangle has a perimeter of 11.5 feet. The side lengths are x feet, 2x – 2 feet, and 3x + 1.5 feet. What is the value of x?
Answer:

We know that the perimeter is the sum of side lengths.

B. (2,0),(-6,2),(-10,3).
C. (-3,5),(-1,-3),(0,-7).
D. (0,2),(2,-6),(3,-10).
Please help me solve this question.
Answer:
C
Step-by-step explanation:
the typical form of line equation is
y = ax + b
a = the slope of the line (expressed as y/x ratio telling us how many units y changes when x changes a certain number of units).
b = the intercept on the y-axis (when x = 0).
we know, a = -4
and we use the point (x = -2, y = 1) to get b
y = -4x + b
1 = -4×-2 + b = 8 + b
b = -7
=>
y = -4x - 7
only the points of option C are all fulfilling this equation.
e.g. x = 0, y = -7
-7 = -4×0 - 7 = -7, true, -7 = -7
and so on.
Which properties did you use in solving the equation? Check all of the boxes that apply.

Hakim and Aziz had some savings in the ratio 3 : 5. Hakim saved another $82 and Aziz spent $110. Both have the same amount of money now. How much do each of them have now?
===========================================================
Explanation:
Hakim and Aziz have savings in the ratio 3:5. This means that Hakim has 3x dollars while Aziz has 5x dollars. The x is some positive real number.
We're then told that Hakim saved another $82, which means it goes from 3x to 3x+82
At the same time, Aziz spent $110 which means the 5x decreases to 5x-110
At this point, the two people have the same amount of money. Set the expressions we found equal to one another and solve for x.
3x+82 = 5x-110
3x-5x = -110-82
-2x = -192
x = -192/(-2)
x = 96
Then use this x value to compute each expression like so
3x+82 = 3*96+82 = 3705x-110 = 5*96-110 = 370Both have $370 after Hakim saved that additional $82 and after Aziz spent that $110.
------------------
Extra info:
If we rewind things a bit, Hakim would have 3*x = 3*96 = 288 dollars while Aziz would have 5x = 5*96 = 480 dollars. This is before any additional saving or spending.
Then note how the ratio 288:480 fully reduces to 3:5 after dividing both parts by the GCF 96.

Write an equation of the line in fully simplified slope-intercept form.
Answer:
Equation is 4y = -3x + 12
Step-by-step explanation:
General equation of a line:
[tex]y = mx + c[/tex]
for the slope:
[tex]slope = \frac{y_{2} - y_{1} }{x _{2} - x_{1} } [/tex]
consider points: (4, 0) and (0, 3)
[tex]slope = \frac{3 - 0}{0 - 4} \\ \\ slope = - \frac{3}{4} [/tex]
for y-intercept, c :
[tex]y = mx + c[/tex]
consider point (0, 3):
[tex]3 = ( - \frac{3}{4} \times 0) + c \\ \\ c = 3 \\ c = 3[/tex]
Equation is:
[tex]y = - \frac{3}{4} x + 3 \\ \\ 4y = - 3x + 12[/tex]
3. Yenny has (6m + 4) sweets. Maria has half as many sweets as Yenny.
Express the total number of sweets they have in its simplest form.
Ans:
Answer:
9m + 6
Step-by-step explanation:
Maria has half as many sweets as Yenny , that is
[tex]\frac{1}{2}[/tex] (6m + 4) ← multiply each term in the parenthesis by [tex]\frac{1}{2}[/tex]
= 3m + 2
Total sweets = 6m + 4 + 3m + 2 ← collect like terms
= 9m + 6

Given h(x) = –2x – 4, solve for x when h(x)
6.
Answer:
x = -16
Step-by-step explanation:
given:
[tex]h(x) = -2x - 4[/tex]
solve for x, when:
[tex]h(x) = 6[/tex]
~~~~~~~~~~~~
➡️ [tex] x = -2(6) - 4 [/tex]
➡️ [tex] x = -12 - 4[/tex]
➡️ [tex] x = -16 [/tex]
The solution of x when the function h ( x ) = 6 is x = -5
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as h ( x )
Now , the value of h ( x ) is given by
h ( x ) = -2x - 4 be equation (1)
On simplifying the function rule , we get
when h ( x ) = 6
Substitute the value of h ( x ) = 6 , we get
6 = -2x - 4
Adding 4 on both sides , we get
-2x = 10
Divide by -2 on both sides , we get
x = 10 / -2
x = -5
Therefore , the value of x is -5
Hence , the equation is x = -5

Question : -2(3)(-11)
Find the distance between the two points rounding to the nearest tenth (if necessary).
(0,-6) and (9,-1)
Hey there! I'm happy to help!
Imagine the line that is created when you connect the two points (the distance between the two points).
You can create a right triangle where this distance is the hypotenuse where the two legs are the change in x and y. So, if you take those changes in x and y, you can use the Pythagorean Theorem (a²+b²=c²) to find the distance between the two points, which is the hypotenuse.
Our change in x is 9 because 9-0 is 9.
We square it
9²=81
Our change in y is 5 as -1-(-6) or -1+6 is 5.
5²=25
We add these.
81+25=106
We square root and round to the nearest tenth.
√106≈10.3
So, our distance is 10.3.
This Pythagorean Theorem method actually gives us a formula called the distance formula that you can use to find the distance between points.
