Answer:
-5
Step-by-step explanation:
3(3x + 5) = 2(2x - 5)
9x + 15 = 4x - 10
9x - 4x = -15 - 10
5x = - 25
x = -5
Find the length of x
An expression is given that has a value between 4.44.4 and 4.54.5, and where xx represents an integer. \sqrt{x}+\sqrt{x} x + x What is the value of xx?
Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
Given
[tex]\sqrt x + \sqrt x = (4.4,4.5)[/tex]
Required
Find x
When the result is 4.4, we have:
[tex]\sqrt x + \sqrt x = 4.4[/tex]
This gives:
[tex]2\sqrt x = 4.4[/tex]
Divide both sides by 2
[tex]\sqrt x = 2.2[/tex]
Square both sides
[tex]x = 2.2^2[/tex]
[tex]x = 4.84[/tex]
When the result is 4.5, we have:
[tex]\sqrt x + \sqrt x = 4.5[/tex]
[tex]2\sqrt x = 4.5\\[/tex]
Divide both sides by 2
[tex]\sqrt x = 2.25[/tex]
Square both sides
[tex]x = 2.25^2[/tex]
[tex]x = 5.0625[/tex]
So, the value of x is between 4.84 and 5.0625
i.e.
[tex]x = (4.84,5.0625)[/tex]
The only integer between the above interval is 5.
Hence:
[tex]x = 5[/tex]

pls someone help quick
NO LINKS!!!!
Answer:
It does not display exponential behavior, so no.
Step-by-step explanation:
x values are consistently decreasing by 3
y values are consistently decreasing by 7
Yes, the set of data shown in the table displays exponential behavior.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The exponential function is given as f(x) = [tex]a^x[/tex]
From the table,
f(x) = [tex]a^x[/tex]
30 = c[tex]a^{21}[/tex] _____(1)
23 = c[tex]a^{18}[/tex] ______(2)
Now,
From (1) and (2)
30/[tex]a^{21}[/tex] = 23/[tex]a^{18}[/tex]
[tex]a^{18 - 21}[/tex] = 23/30
[tex]a^{-3}[/tex] = 23/30
1/[tex]a^3[/tex] = 23/30
a³ = 30/23
a = ∛(30/23)
a = 1.09
Now,
30 = c[tex]a^{21}[/tex]
30 = c x [tex]1.09^{21}[/tex]
c = 30 / 6.11
c = 4.91
Now,
The function from the table is f(x) = 4.91 x [tex]1.09^x[/tex]
Thus,
The set of data is an exponential function.

Given f (x) = 5x2 and g(x) = 2x + 3, find f(g(-4))
Answer:
125
Step-by-step explanation:
Given
f(x) = 5x²
g(x) = 2x + 3
Now
g(-4) = 2 * (- 4) + 3
= - 8 + 3
= - 5
Also
f(g(-4)) = f( -5)
= 5 * ( -5)²
= 5 * 25
= 125

Kameron's unicycle wheel has a spoke length of 16 inches.
16 in.
Approximately how many inches of ground does Kameron cover in 3 full rotations of the unicycle wheel? (Use 3.14 as an approximation of pi.)
Answer:
301.44 inches
Step-by-step explanation:
The spoke is from the center of the wheel to the edge, so its length is the radius, or 16 inches.
You want to find the distance that one rotation will take you, so you need the wheel's circumference.
Circumference = 2πr
2 x 3.14 x 16 = 100.48
100.48 inches is the distance of only 1 full rotation, so you just need to multiply 100.48 by 3 to get the distance of 3 rotations.
100.48 x 3 = 301.44

3/5 of the pupils in Year 9 say their favourite colour is red.
There are 80 pupils in Year 9.
How many students said red is their favourite colour?
Answer:
48
Step-by-step explanation:
Since 80 pupils is the total amount of pupils in Year 9...
5/5 = 80
1/5 = 80 ÷ 5 = 16
3/5 = 16 x 3 = 48 (The amount of pupils who said red is their favourite colour in Year 9)
find the value of r so that the line through (2,-3) and (-4,r) has a slope of -1/2 | please explain steps
Answer:
r = 0
Step-by-step explanation:
slope formula is the difference of the y-values over the difference of the x-values
[r-(-3) / -4-2] = -1/2
r+3/-6 = -1/2
cross-multiply:
2(r+3) = (-1)(-6)
2r + 6 = 6

. How many minutes is it from 23:35 today to 01:15 tomorrow?
A 100
B 110
C 120
D 130
E 140
Answer:
A (100)
Step-by-step explanation:
If 2 hours pass starting at 23:35 today, then tomorrow the time will be 1:35. The difference between 1:35 and 1:15 is 20 (minutes) Because there are 120 minutes in 2 hours (60 minutes per hour), This means we do 120 minutes minus 20 minutes. This gives us an answer is A, 100 :)
