Answer:
It is not a triangle
Step-by-step explanation:
The Triangle Inequality theorem states that in a triangle, [tex]a+b>c[/tex], where [tex]a[/tex] and [tex]b[/tex] are shorter side lengths and [tex]c[/tex] is the longest side length.
Given that [tex]5+9<15[/tex], the given side lengths do not compose a valid triangle.
type of solution for x(5−2)=4x−x
Answer:
X=2
Step-by-step explanation:
X(5-2)=4x-x
5x-2x=4x-x (then moving everything to one side)
5x-2x-4x+x=0 (5x-4x-x=5x-5x which is 0)
-2x=0
X=2

Let the cost of 2 pair of boots be A
Now , the cost of pair of boots = 145 % the cost of pair of sneakers
Substituting the values in the equation , we get
The cost of pair of sneakers = $ 21
So , the cost of pair of boots = ( 1.45 ) x 21
The cost of pair of boots = $ 30.45
Now , the cost of 2 pair of boots A = 2 x cost of pair of boots
On simplifying , we get

Alvita is planning a garden patio to be made from identical square paving stones laid out in a rectangle
measuring 2 stones by y stones.
She finds that when she adds a border of width one stone around the patio, the area of the border is equal
to the original area of the patio.
How many possible values for x are there?
The length of the square paving is the base unit to which the area of the
and patio and the border are evaluated.
Correct response:
The possible x-values are; 10, 6, 4, and 3Which method is used to evaluate the area of the patio?Let s represent the size of the square paving, we have;
Area of the patio = s·x × s·y = s²·x·y
New area = (2·s + s·x) × (2·s + s·y) = 4·s² + 2·s²·y + 2·x·s² + s²·x·y
Area of the border = 4·s² + 2·s²·y + 2·x·s² = s²·x·y
2·s²·(2 + y + x) = s²·x·y
2·(2 + y + x) = x·y
4 + 2·y + 2·x = x·y
x·y - 2·x = 4 + 2·y
x·(y - 2) = 4 + 2·y
Which by using gives;

Slope = 2; (14, 33)
Answer:
y = 2x + 5
Step-by-step explanation:
Consider the format of a line equation, y = mx + b
The slope is represented as the variable 'm.'
Since we already know that the slope is 2, we can input it into the format.
y = 2x + b
Assuming that the point (14, 33) is a point of intersection, we can input these numbers into the equation in order to find the value of b, or the y-intersect.
33 = 2(14) + b
33 = 28 + b

The Greens bought a condominium for $110,000 in 2010. If its value appreciates at an average rate of 6% per year, what will the value be in 2015?
Answer:
Value in 2015 will be $ 143,000
Step-by-step explanation:
Data :
Value in 2010 = $ 110000
Increase rate = 6%
6% of 110000 = (11000×6)÷100 = 6600

help!!! how do i solve this
Answer:
(a) 7.1
(b) (5/2, 3/2)
(c) 2
(d) y = -x +4
Step-by-step explanation:
(a)The length of AC is found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((5 -(-2))² +(-1 -0)²) = √(49 +1) = 5√2 ≈ 7.1
The length of AC is about 7.1.

(b)The midpoint has coordinates that are the average of the end point coordinates.
midpoint BC = (B + C)/2 = ((0, 4) +(5, -1))/2 = (5, 3)/2
midpoint BC = (5/2, 3/2)
__
(c)The slope is found using the slope formula.
m = (y2 -y1)/(x2 -x1)
For points A(-2, 0) and B(0, 4), the slope of the segment between them is ...
m = (4 -0)/(0 -(-2)) = 4/2 = 2
The slope of AB is 2.
__
(d)The slope of line BC is found in the same was as for AB.
m = (-1 -4)/(5 -0) = -5/5 = -1
The y-intercept of the line is point B, at y=4. So, the equation of line BC is ...
y = mx +b . . . . . where m is the slope, and b is the y-intercept
y = -x +4
Does (2,0) work as a solution to the systems of equations to lines 3x+y=6 and 3x-y=6
Answer:
Yes
Step-by-step explanation:
To see if (2,0) works as a solution to the systems of equations, we plug in the values of x and y and simplify. If the results are equal, then (2,0) is a solution.
3x + y = 6:
[tex]3(2) + 0 = 6[/tex] [tex]6 + 0 = 6[/tex] [tex]6 = 6[/tex] (2,0) is a solution to this equation.3x - y = 6:
[tex]3(2) - 0 = 6[/tex] [tex]6 - 0 = 6[/tex] [tex]6 = 6[/tex] (2,0) is a solution to this equation.Therefore, the answer is yes, it does work as a solution.

You deposit $7550 in an account that pays 7.25% interest, compounded continuously. How long to the
nearest year will it take for the money to triple?
[tex]~~~~~~ \textit{Continuously Compounding Interest Earned Amount} \\\\ A=Pe^{rt}\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$\stackrel{tripled}{(7550)3}\\ P=\textit{original amount deposited}\dotfill & \$7550\\ r=rate\to 7.25\%\to \frac{7.25}{100}\dotfill &0.0725\\ t=years \end{cases}[/tex]
[tex]3(7550)=7550e^{0.0725\cdot t}\implies \cfrac{3(7550)}{7550}=e^{0.0725t}\implies 3=e^{0.0725t} \\\\\\ \log_e(3)=\log_e\left( e^{0.0725t} \right)\implies \ln(3)=0.0725t \\\\\\ \cfrac{\ln(3)}{0.0725}=t\implies 15.15327\approx t\implies 15\approx t[/tex]
It will take approximately 9.55 years (rounded to the nearest year) for the money to triple.
Here, we have,
To determine how long it will take for the money to triple, we need to use the continuous compound interest formula:
A = P *[tex]e^{rt}[/tex],
where:
A = final amount (triple the initial amount)
P = principal amount (initial deposit)
e = Euler's number (approximately 2.71828)
r = interest rate
t = time (in years)
In this case, we have:
P = $7550
r = 7.25% = 0.0725 (converted to decimal)
A = 3P (triple the initial amount)
Substituting these values into the formula, we have:
3P = P *[tex]e^{rt}[/tex]
Dividing both sides of the equation by P, we get:
3 = [tex]e^{rt}[/tex]
To isolate the variable t, we take the natural logarithm (ln) of both sides:
ln(3) = ln[tex]e^{rt}[/tex]
Using the logarithmic property that ln(eˣ) = x, we have:
ln(3) = rt * ln(e)
Since ln(e) = 1, the equation simplifies to:
ln(3) = rt
Now, we can solve for t by dividing both sides by r:
t = ln(3) / r
Substituting the values:
t = ln(3) / 0.0725
Using a calculator or software, we find:
t ≈ 9.55 years (rounded to two decit will take approximately 9.55 years (rounded to the nearest year) for the money to triple. deimal places)
Therefore, it will take approximately 9.55 years (rounded to the nearest year) for the money to triple.

Answer:
x ≈ 33.0
Step-by-step explanation:
The third angle in the triangle is
180° - 70° - 76° = 180° - 146° = 34°
Using the Sine rule in the triangle
[tex]\frac{x}{sin76}[/tex] = [tex]\frac{19}{sin34}[/tex] ( cross- multiply )
x × sin34° = 19 × sin76° ( divide both sides by sin34° )
x = [tex]\frac{19sin76}{sin34}[/tex] ≈ 33.0 ( to the nearest tenth )
Answer:
x=33 (since it says to round it)
Step-by-step explanation:
This is an ASA triangle.
First, we need to find the value of the unlabeled angle, which is simple:
180°-70°-76°=34° Lets call that angle A
Now we use the law of sines:
x/sinX = a/sinA
x/sin76° = 19/sin34°
Then:
x = (19/sin34°) × sin76°
x = 32.968

Step-by-step explanation:
To dilate a point, you simply multiply the scale factor (1/3) by the x- and y-values of the point:
6 x 1/3 = 2
-3 x 1/3 = -1
Therefore, the new point would be (2,-1)
