Answer:
Second option from the top
Step-by-step explanation:
First, let us simplify x + 2 < -3
x + 2 < -3
x + 2 - 2 < -3 - 2
x < -5
Now we can more clearly see which graph is correct.
-> Since we are using < / > and not ≤ / ≥ the dot will be opened and not closed. This rules out the first and third options.
-> Next, we need the direction of the line. Since < is facing to the left, our line will also be going to the left.
-> To satisfy all requirements, since all graphs start at -5 already, the correct answer is the second option from the top.
Answer:
it's the second one
Step-by-step explanation:
it's all just common knowledge
the sign is a less than sign so the sign is an open dot. That eliminated two options. And whatever way the less than sign is pointing is the way the arrow goes

Step-by-step explanation:
mark me brainliest!!
Answer: A
Step-by-step explanation:
Let the length side of the TV = a
The width of the TV = b
The diagonal of a TV = c
In a 30-60-90 right triangle,
We have cos(30°) = [tex]\frac{\sqrt{3}}{2}[/tex] and sin(30°) = [tex]\frac{1}{2}[/tex]
Given that c = 28 inches:
sin(30°) = [tex]\frac{b}{c}[/tex]
[tex]\frac{1}{2} = \frac{b}{c}[/tex]
[tex]b = \frac{1}{2} \times 28 = 14[/tex]
That is, the width of the TV = 14 inches
cos(30°) = [tex]\frac{a}{c}[/tex]
[tex]\frac{\sqrt{3}}{2} = \frac{a}{c}[/tex]
[tex]a = \frac{\sqrt{3}}{2} \times 28 = 14\sqrt{3}[/tex]
That is, the length of the TV = 14√3 inches
So the exact width and length of the TV are 14 inches and 14√3 inches.
Therefore, option A is the correct answer

The surface area of a rectangular prism is 174 square inches. The rectangular base has one side length 3 times the other. The height of the prism is 5 inches. What are the maximum lengths of the sides of the base?
Answers
The maximum lengths of the sides of the rectangular base are approximately 7.616 inches and 22.847 inches.
How to find the maximum lengths of the sides of the baseThe surface area of the rectangular prism ([tex]A_{s}[/tex]) is equal to the product of two lengths of triangle. The area formula for the base is:
[tex]A = x\cdot (3\cdot x)[/tex]
[tex]A = 3\cdot x^{2}[/tex]
If we know that [tex]A = 174[/tex], then the least length of the base of the rectangle is:
[tex]x = \sqrt{\frac{A}{3} }[/tex]
[tex]x \approx 7.616\,in[/tex]

q(a+1) - 2q(a) if q(x) = x²+3x+4
Answers
[tex]q(x) = {x}^{2} + 3x + 4 [/tex]
_________________________________
Step(1)
To find q(a) we just need to put a instead of x in q(x) function.
Let's do it...
[tex]q(a) = {a}^{2} + 3a + 4 [/tex]
Multiply sides by -2 :
[tex] - 2q(a) = - 2( {a}^{2} + 3a + 4) [/tex]
[tex] - 2q(a) = - 2 {a}^{2} - 6a - 8 [/tex]
_________________________________
Step (2)
To find q(a+1) we just need to put a+1 instead of x in q(x) function.
Let's do it...
[tex]q(a + 1) = ({a + 1})^{2} + 3(a + 1) + 4 \\ [/tex]
[tex]q(a + 1) = {a}^{2} + 2a + 1 + 3a + 3 + 4 \\ [/tex]
[tex]q(a + 1) = {a}^{2} + 5a + 8 [/tex]

The expression for q(a+1) - 2q(a) is -a² - a
Given the expression q(x) = x²+3x+4
First, we need to get the function q(a+1)
q(a+1) = (a+1)²+3(a+1)+4
Expand
q(a+1) = a² + 2a + 1 + 3a + 3 + 4
q(a+1) = a² + 5a + 8
For the function q(a)
q(a) = a²+3a+4
2q(a) = 2(a²+3a+4)
2q(a)= 2a² + 6a + 8
Taking the difference:
q(a+1) - 2q(a) = a² + 5a + 8 - ( 2a² + 6a + 8)
q(a+1) - 2q(a) = a² + 5a + 8 - 2a² - 6a - 8
q(a+1) - 2q(a) = -a² - a
Hence the expression for q(a+1) - 2q(a) is -a² - a

on 11 days of these 14 he had fever.
that means on 14-11 = 3 days he did not have a fever.
on 9 of these 11 fever days he had the fever in the evening.

Therefore, the shape shown is a regular polygon (hexagon).
Exterior angle of a regular polygon = 360 ÷ number of sides
⇒ Exterior angle of a regular hexagon = 360 ÷ 60 = 60°
Therefore,
4x - 8 = 60
Add 8 to both sides:

A loaf of bread costs Rs.0.79 today. If its price increases by 6% per year, how much will an equivalent loaf cost in 20 years?
Answers
Answer:
.79x(.06x20)=.948
round up to .95
Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. The price of the loaf of bread after 20 years will be 2.53.
What is compounding?Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. And this continues for t period of time.
It is given by the formula,
A = P(1+r)ⁿ
where A is the value after n period of time, P is the initial amount, and,
r is the rate of increment or decrement.
Given that a loaf of bread costs Rs.0.79 today, and its price increases by 6% per year. Therefore, the price of bread will increase every year by 6% of the previous year's cost. Thus, it can be concluded that the price increases compounding.
Therefore, the equivalent loaf cost in 20 years will be,
Cost of the loaf after 20 years = 0.79(1+0.06)²⁰
= 0.79(3.2071)
= 2.53
Hence, the price of the loaf of bread after 20 years will be 2.53.

Answer: 3
The maximum number of people who can go to the amusement park will be 3.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that the group has $140 to spend on parking and admission. Parking is $5.75, and tickets cost $39.75 per person, including tax.
For the inequality, we have to apply the arithmetic operation in which we do the multiplication of x and apply the inequality for the given data.
Suppose the number of people will be n.
39.75n + 5.75 ≤ 140
39.75n ≤ 134.25
