Which value of x satisfies the equation 5(2x-9)+3=-7
Answer:
x = 7 / 2
Step-by-step explanation:
5(2x - 9) + 3 = -7 ---------- subtract 3 from both sides
5(2x - 9) + 3 - 3 = -7 - 3
5(2x - 9) = -10 ------ divide both side by 5
2x - 9 = -2 ---------- add 9 to both sides
2x - 9 + 9 = -2 + 9
2x = 7
x = 7 / 2

find the slope (0, -3) and (9, 0) PLEASE SHOW YOUR WORK, WILL MARK BRAINLEIST
===================================================
Work Shown:
Use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (0 - (-3))/(9 - 0)
m = (0 + 3)/(9 - 0)
m = 3/9
m = 1/3
----------------
Basically we subtract the y coordinates, and do the same for the x coordinates as well (subtract in the same order). Afterward, divide the two results. Reduce the fraction as much as possible.
A slope of 1/3 means we move up 1 unit each time we move to the right 3 units.
The slope being positive means the line goes uphill as you read from left to right.
if c(x)= 5/x-2 and d(x)=x+3, what is the domain of (cd)(x)
Answer:
Step-by-step explanation:
cd(x) would equal c(x) multiplied by d(x) so we get [tex]\frac{5(x+3)}{x-2}\\[/tex] = [tex]\frac{5x+15}{x-2}\\[/tex].
The domain of [tex]\frac{5x+15}{x-2}[/tex] is anything except 2, so the domain of (cd)(x) is (-inf, 2) U (2, inf).

The number of people living in a country is increasing each year exponentially so that the number of people 5 years ago was 15,000. The number of people now is 26,000. What is the present population of the country? What equation can we use to describe the situation, if we let the growth rate be represented by r? Solve the equation for r. What is the growth rate? What will the population be 5 years from today?
Answer:
The present population of the country is 26,000.
[tex]y=a(1+r)^{x}[/tex]
The growth rate is approximately 12%.
The population 5 years from today will be 45,821.
Step-by-step explanation:
(1)
The present population of the country is 26,000.
(2)
It is provided that the number of people living in a country is increasing each year exponentially.
Then the exponential growth function can be used to describe the situation.
The exponential growth function is:
[tex]y=a(1+r)^{x}[/tex]
Here,
y = final value
a = initial value
r = growth rate
x = time
(3)
It is provided that x = 5 years ago the population was a = 15,000 and at present the population is y = 26,000.
Compute the value of r as follows:
[tex]y=a(1+r)^{x}[/tex]
[tex]26000=15000\times (1+r)^{5}[/tex]
[tex](1+r)=[\frac{26000}{15000}]^{1/5}[/tex]
[tex]1+r=1.1163[/tex]
[tex]r=0.1163\\r\approx 0.12[/tex]
Thus, the growth rate is approximately 12%.
(4)
Compute the population 5 years from today as follows:
[tex]y=a(1+r)^{x}[/tex]
[tex]=26000\times (1+0.12)^{5}\\\\=26000\times 1.762342\\\\=45820.892\\\\\approx 45821[/tex]
Thus, the population 5 years from today will be 45,821.

The temperature of a town at 3:00 p.m. was
41 °C. The temperature recorded at 9:00 p.m.
was 29 °C. Find the fall in temperature per
hour, if the temperature falls at a constant rate
per hour.
Answer:
-2° per hour
Step-by-step explanation:
3 PM => 41°
9 PM => 29°
Find the temperature fall rate.
First, there are 6 hours between 3 and 9, and the temperature decreased 41 - 29 = 12° in those 6 hours. To find the rate, simply divide the degrees difference by the number of hours => 12/6 = 2° per hour; and since it's a descending rate, you put a negative ( -2°).

An ant starts at (0, 0), and only makes moves of length 1 in the positive x directions or the positive y direction. How many paths are there from the ant that end at (3, 3) but never pass through (2, 3)
Answer:
The number of paths that are there from the ant that end at (3, 3) but never pass through (2, 3) is 4.
Step-by-step explanation:
The possible pathways are as follows:
(0, 0) → (1, 0) → (2, 0) → (3, 0) → (3, 1) → (3, 2) → (3, 3)
(0, 0) → (1, 0) → (2, 0) → (2, 1) → (2, 2) → (3, 2) → (3, 3)
(0, 0) → (1, 0) → (1, 1) → (1, 2) → (2, 2) → (3, 2) → (3, 3)
(0, 0) → (0, 1) → (0, 2) → (1, 2) → (2, 2) → (3, 2) → (3, 3)
Thus, the number of paths that are there from the ant that end at (3, 3) but never pass through (2, 3) is 4.

An angle measures 28° less than the measure of its complementarylangle. What is the
measure of each angle?
Answer:
59 degrees and 31 degrees.
Step-by-step explanation:
Complementary angles form a 90 degree angle. Let's say that one angle measures x degrees. If one angle is x degrees, the other measures 28 degrees less. So, the other measures x - 28 degrees.
x + (x - 28) = 90
2x - 28 = 90
2x = 118
x = 59 degrees.
The other angle measure will then be 59 - 28 = 31 degrees.
Hope this helps!
Answer:
59° and 31°
Step-by-step explanation:
Complementary angle sum 90°
a + b = 90
a = b - 28
then:
(b - 28) + b = 90
2b - 28 = 90
2b = 90 + 28
2b = 118
b = 118/2
b = 59°
a = b - 28
a = 59 - 28
a = 31°
Probe:
59° + 31° = 90°

Find Y
..............
Answer:
y = 40 / sqrt(pi)
Step-by-step explanation:
The area is 400
We want to find the diameter
400 = pi r^2
Divide each side by pi
400/ pi = r^2
Take the square root of each side
sqrt(400/ pi) = sqrt(r^2)
20/ sqrt(pi) = r
The diameter is twice the radius
2 r = d
2 * 20/ sqrt(pi) = d
40 / sqrt(pi) =d
y is the diameter so
y = 40 / sqrt(pi)
TW¯¯¯¯¯¯¯¯¯=3, CW¯¯¯¯¯¯¯¯¯=x, TU¯¯¯¯¯¯¯=x+7, VW¯¯¯¯¯¯¯¯¯=6. Find the value of x.
Answer:
x = 4
Step-by-step explanation:
TW = 3
WU = TU - TW = x + 7 - 3 = x + 4
CW = x
VW = 6
By the property of intersecting chords inside a circle, we have:
TW * WU = CW * VW
3(x + 4) = x * 6
3x + 12 = 6x
12 = 6x - 3x
12 = 3x
12/3 = x
4 = x
x = 4
The value of x is 4.
What is the intersecting chords theorem?The chord theorem is defined as a statement in basic geometry that explains the relationship between the four line segments formed by two intersecting chords inside of a circle. According to this statement, the products of the line segment lengths on each chord are equal. It is also known as the intersecting chords theorem.
According to given figure,
TW = 3,
CW = x,
VW = 6,
Chord TU = x + 7,
WU = TU - TW
Substitute the value of Chord TU in above equation,
WU = x + 7 - 3
WU = x + 4
According to property of intersecting chords inside a circle, the products of the line segment lengths on each chord are equal.
TW × WU = VW × CW
3(x + 4) = 6 × x
3x + 12 = 6x
12 = 6x - 3x
12 = 3x
x = 12/3
x = 4
Hence, the value of x is 4.
