Answer:
x > - 3
Step-by-step explanation:
x + 2[tex]\frac{1}{2}[/tex] > - [tex]\frac{1}{2}[/tex] First turn 2[tex]\frac{1}{2}[/tex] into an fraction since its easier. So it becomes [tex]\frac{5}{2}[/tex]
x + [tex]\frac{5}{2}[/tex] > - [tex]\frac{1}{2}[/tex]
- [tex]\frac{5}{2}[/tex] - [tex]\frac{5}{2}[/tex] Do inverse operations, so subtract [tex]\frac{5}{2}[/tex] from both sides.
x > - [tex]\frac{6}{2}[/tex] Combine - [tex]\frac{5}{2}[/tex] with - [tex]\frac{1}{2}[/tex], which gives us - [tex]\frac{6}{2}[/tex]
x > - 3 Since we know that 6 divided by 2 is 3.
This would not allow me to attach an image so I am going to type a visual representation f what the graph would look like below)
<-------------O--------------------------------------------------->
-5 -4 -3 -2 -1 0 1 2 3 4 5
So, the number line would be a solid line rather than dashed (but I was not able to attach an image so I kind of had to improvise). When using ≥ ≤ sings the circle of the point is closed. When using < and > signs, the circle of the point is open. Thus, in this scenario since he sign is >, then the circle of the point is open. The direction of the arrow and ray for this equality is going to the right because the answer is that x is greater than - 3, Therefore any values greater than - 3 are a possibility which is why the arrow goes on indefinitely.

Remember, adjectives in Spanish agree with the gender of the noun they describe.
Por ejemplo: el chico ordenado / la chica artística
Answer:
1) A serious girl - Una chica seria/Una joven seria
2) The talented boy - El chico talentoso/El joven talentoso
3) An outgoing girl - Una chica extrovertida/Una joven extrovertida
4) The tasty ice cream - El helado delicioso/El helado sabroso
5) A funny book - Un libro divertido/Un libro entretenido

Now, we present a possible set of solution, as there are solutions as many synonyms exist in Spanish. Then:
1) A serious girl - Una chica seria/Una joven seria
2) The talented boy - El chico talentoso/El joven talentoso
3) An outgoing girl - Una chica extrovertida/Una joven extrovertida
4) The tasty ice cream - El helado delicioso/El helado sabroso
5) A funny book - Un libro divertido/Un libro entretenido

If h = 18 units and r = 9 units, then what is the volume of the cone shown above
A. 234 cubic units
B. 1,458 cubic units
C. 972 cubic units
D. 486 cubic units
Answer:
Volume = 1526.04 cubic units
Step-by-step explanation:
Formula for volume of a cone:
V = πr²h/3
If we use 3.14 for pi, we get 1526.04:
V = 3.14(9)^2(18)/3
V = 1526.04

Four different linear functions are represented below. Drag the representation of each function into order from greatest y -intercept to least y -intercept.
Answer:
Descending order intercept : y = 5x + 4 , y = 4x + 3 , y = 3x + 2 , y = 2x + 1
Step-by-step explanation:
Linear Equations are in form of 'y = mx + b'.
Here, b is y intercept & it represents autonomous ie constant value of y irrespective of value of x. And, m represents slope ie change in y due to change in x.
Eg : 'y = 2x + 1' has least y intercept ie common autonomous value ie 1. y = 3x + 2 , y = 4x + 3 , y = 5x + 4 ; these have higher & higher y intercepts respectively.
Arrangement from greatest to highest intercept (descending order of intercept) of above : y = 5x + 4 , y = 4x + 3 , y = 3x + 2 , y = 2x + 1

Find the product of 12 and 8. Find the greatest common factor of 12 and 8. Find the least common multiple of 12 and 8. Find the product of the greatest common factor and the least common multiple of 12 and 8.
Answer:
Product: 96
GCF: 4
LCM: 24
Product of the GCF and LCM: 96
Step-by-step explanation:
Product - The answer to a multiplication problem.GCF - The greatest positive integer that evenly divides both numbers.LCM - The smallest multiple that both numbers have in common.Now that we know what definitions are, we can solve this word problem.
12 × 8 = 96.
96 is the product.
To find the greatest common factor, we can list all of the factors for each number.
12: 1, 2, 3, 4, 6, 12
8: 1, 2, 4, 8
The largest factor both numbers have in common is 4.
Therefore, 4 is the greatest common factor.
To find the least common multiple, we can list the multiples of both numbers.
12: 12, 24, 36, 48, 60, 72, 84, 96
8: 8, 16, 24, 32, 40, 48, 56, 64
The smallest multiple both numbers have in common is 24.
Therefore, 24 is the least common multiple.
Lastly, we have to find the product of the GCF and the LCM.
The GCF is 4 and the LCM is 24.
4 × 24 = 96.
96 is the product.
Therefore, 96 is the product of the greatest common factor and the least common factor of 12 and 8.

3. What is the value of the 8 in 0.283? Select ALL that apply. *
0.8
0.08
8 x 1/10
8 x 1/100
eight hundredths
Answer:
0.08, 8 hundreths, 8 x 1/100
Step-by-step explanation:
The first digit before the decimal is a unit.
The first digit after the decimal point is called a tenth
The second digit after the decimal point is called hundreths
The third digit after the decimal point is called a thousandths
The 8 is the second digit after the decimal point.
Therefore the answer is eight hundreths or represented by the decimal form of 0.08
It is also 8 x 1/100 because if we multiply this we get 0.08
Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
a) y(x) = (x + 2)^2 -2
b) minimum
c) (-2, -2)
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
Given
y = x² + 4x + 2
(a)
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + 4x
y = x² + 2(2)x + 4 - 4 + 2
y = (x + 2)² - 2
(b)
Since a = 1 > 0 then vertex is minimum
(c)
(h, k ) = (- 2, - 2 ) ← coordinates of vertex

A quadratic equation is shown below: x2 − 8x + 13 = 0 Which of the following is the first correct step to write the above equation in the form (x − p)2 = q, where p and q are integers? (5 points) Subtract 5 from both sides of the equation Subtract 3 from both sides of the equation Add 5 to both sides of the equation Add 3 to both sides of the equation
Answer:
Add 3 to both sides of the equation
Solution:
The first step is to basically realize that all it's asking you to do is to find a way to make the expression on the left ([tex]x^2 - 8x + 13[/tex]) into an expression that is a perfect square. So what number should you add to both sides such that [tex]x^2 - 8x + (13 + j)[/tex] can be factored into [tex](x-p)^2[/tex] ? Well, we can approach it like this:
Since [tex](x-p)^2[/tex] can be turned into [tex]x^2 -2px + p^2[/tex], and our original form was [tex]x^2 - 8x + (13 + j)[/tex], we quickly realize that [tex]-2px = -8x[/tex]. From there, we can easily tell that [tex]p = 4[/tex]
Plug this into our last value [tex]p^2[/tex] to get 16. Therefore, if we compare this with our original equation again [tex]x^2 - 8x + (13 + j)[/tex], we notice that 13 + j = 16.
Thus, j = 3 for the last answer.
Add 3 to both sides of the equation.
Note: With more practice, you will quickly gain enough intuition to notice that [tex]x^2 - 8x + 13[/tex] is very close to [tex]x^2 - 8x + 16[/tex] which can be factored into [tex](x-4)^2[/tex]. But for now, the solution above will suffice. I hope this helps :))

(x - 7)2 + (y + 5)2 = 4
what’s the center and radius
Answer:
(7, - 5 ) and r = 2
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 7)² + (y + 5)² = 4 ← is in standard form
with centre = (h, k ) = (7, - 5 ) and r = [tex]\sqrt{4}[/tex] = 2

The size of a TV is the diagonal
measurement of its screen. Will a
46-inch TV fit in a rectangular cabinet
measuring 32 inches long and
28 inches high? Explain.
Answer:
Use the Pythagorean Theorem to calculate the length of the sides of a right triangle. A TV cut in half on the diagonal is a right triangle.
a^2 + b^2 = c^2
a is the width of the TV
b is the height of the TV
c is the diagonal size of the TV
a is equal to the length of b plus 15, and c is equal to 75. If we out those values into the formula, we get this:
(b+15)^2 + (b)^2 = (75)^2
Factoring that out, we get:
(b)^2 + 225 + (b)^2 = 5625
Then..
2b^2 = 5625 - 225
2b^2 = 5400
b^2 = 5400/2
b^2 = 2700
b = ✓2700
b = 51.9615242271 (round it to an even 52)
Next, we know that a = b + 15, so a = 67.
Therefore, the width of the TV is 67 inches, the height is 52 inches, the diagonal is 75 inches, and you have a very strangely shaped television with a 1.288 (approximately 5:4) aspect ratio. Older “square” TVs mostly had a 1.33 (4:3) ratio, and new TVs are usually either 16:9 (1.77) or 21:9 (2.33). While it's not impossible that you have an old square TV with a 75 inch diagonal, it's pretty unlikely…
