Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
Whenever the sign is greater than, the line needs to go to the right. Moreover, when it also is equal to, the dot must be shaded. The dot also needs to be on -10 in this instance.
In short, shaded dot on -10 going to the right.

You've gone to fruit stand to get some fresh produce. You
notice that the person in front of you gets 5 apples and 4 oranges
for 10 dollars. You get 5 apples and 5 oranges for 11 dollars.
Create a system of equations that represents this situation.
Step-by-step explanation:
Let $x be the price of an apple and $y be the price of an orange.
5x + 4y = 10
5x + 5y = 11
btw the solution is
y = 1
x = 6/5

A women is twice as old as her daughter . twenty one years ago she was three times her daughter . What is the women's present age?
Answer:
84
Step-by-step explanation:
women=x
daughter=y.
x=2y.
x-21=3(y-21).
2y-21=3y-63.
42=y.
x=84.
Hope this helps plz hit the crown :D
Answer:
Daughter's present age = 42 years
Women's present age = 84 years
Step-by-step explanation:
Daughter's present age = x years
Women's present age = 2*x = 2x
21 years ago:
Daughter's age = x - 21
Women's age = 2x - 21
Women's age = 3*daughter'sage
2x - 21 = 3*(x - 21)
2x - 21 = 3x - 63 {Subtract '2x' from both sides}
- 21 = 3x - 2x - 63
-21 = x - 63 {Add 63 to both sides}
-21 +63 = x
42 = x
Daughter's present age = 42 years
Women's present age = 2*42 = 84 years

Solve for x.
−3x + 2b > 8
Answer:
x<2/3b+-8/3
Step-by-step explanation:
Let's solve for x.
−3x+2b>8
Step 1: Add -2b to both sides.
2b−3x+−2b>8+−2b
−3x>−2b+8
Step 2: Divide both sides by -3.
-3x/-3>-2b+8/-3
x<2/3b+-8/3
Answer is : x<2/3b+-8/3
The director of the admissions at a large university advises parents of incoming students about the cost of textbooks during a typical semester. He selected a sample of 100 students and recorded their textbook expenses for the semester. He then computed a sample mean cost of $315.40 and a sample standard deviation of $43.20
Required:
Using the 0.10 level of significance, is there evidence that the population mean is above $300?
Answer:
The calculated value t = 3.5648> 1.9842 at 0.1 level of significance
The null hypothesis is rejected
The mean of the sample does not come from the Population
Step-by-step explanation:
Step(i):-
Given that sample size 'n' = 100
Mean of the sample x⁻ = 315.40
The standard deviation of the sample (s) = 43.20
Level of significance = 0.1
Mean of the Population = 300
Null hypothesis: H₀: x₀ = μ
Alternative Hypothesis: H₁: x₀ ≠ μ
Step(ii):-
Test statistic
[tex]t = \frac{x^{-}-mean }{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{315.40-300 }{\frac{43.20}{\sqrt{100} } }[/tex]
t = 3.5648
Degrees of freedom = n-1 = 100-1 =99
[tex]t_{\frac{0.1}{2} , 99} = t_{0.05,99} = 1.9842[/tex]
The calculated value t = 3.5648> 1.9842 at 0.1 level of significance
The null hypothesis is rejected
The mean of the sample does not come from the Population
Two angles of a triangle have the same measure and the third one is 3 degrees greater than the measure of each of the other two. Find the measure of the LARGEST angle in the triangle.
9514 1404 393
Answer:
62°
Step-by-step explanation:
If x is the largest angle, the sum of angles in the triangle is ...
x + (x -3) +(x -3) = 180
3x -6 = 180 . . . . . simplify
x -2 = 60 . . . . . . . divide by 3
x = 62 . . . . . . . . . .add 2
The largest angle is 62°.

28% of the students voted for Julie as 8th grade Class President. If she got 126 votes, how
many students are in the 8th grade class?
Answer:
450
Step-by-step explanation:
[tex] \frac{28}{100} = \frac{126}{x} \\ \frac{7}{25} = \frac{126}{x} \\ 7x = 126 \times 25 \\ x = \frac{126 \times 25}{7} = 450[/tex]
or

2) What is 18th term in this sequence: 45, 49, 53, 57,
Answer:
a₁₈ = 113
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 49 - 45 = 53 - 49 = 57 - 53 = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 45 and d = 4, then
a₁₈ = 45 + (17 × 4) = 45 + 68 = 113

A store purchased a hammock and marked it up 125% from the original cost of $36.57.
Then, wanting to make room for summer inventory, the store placed the hammock on sale for
45% off. What was the price after the discount?
If necessary, round your answer to the nearest cent.
Answer:
$20.57
Step-by-step explanation:
36.57 x 125% (or 1.25) = $45.7125
and
$45.7125 x 45% (or .45) = $20.570625 which rounded up is $20.57
Two of the steps in the derivation of the quadratic formula are shown below.
Step 6: = b^2-4ac/4a^2= ( x+b/2a )^2
Step 7: = +✔️b^2-4ac/2a= x + b/2a
Which operation is performed in the derivation of the quadratic formula moving from Step 6 to Step 7?
subtracting b/2a from both sides of the equation squaring both sides of the equation taking the square root of both sides of the equation taking the square root of the discriminant
Answer:
taking the square root of both sides of the equation
Step-by-step explanation:
The operation which is performed in the derivation of the quadratic formula moving from Step 6 to Step 7 is taking the square root of both sides of the equation.
What are Quadratic Equations?Quadratic equations are polynomial equations of second degree.
The general form of a quadratic equation is ax² + b x + c = 0.
Given two steps in deriving the quadratic formula which is used to find the roots of a quadratic equation.
The first step is,
step 6 : (b² - 4ac) / (4a)² = (x + b / 2a)²
step 7 : ± √(b² - 4ac) / 2a = x + b / 2a
We have to find which step is done in between to transform from step 6 to step 7.
It is clear that square root is taken.
When the square root is taken in step 6,
±√[(b² - 4ac) / (4a)²] = √[(x + b / 2a)²]
√(b² - 4ac) / √(4a)² = √(x + b / 2a)²
± √(b² - 4ac) / 2a = x + b / 2a
Hence the step performed is taking the square root on both sides.

What does "solution" mean?
What does it mean for a point to be a solution to a linear
equation?
For example, if I say, " (2,5) is a solution to the
equation y = 2x + 3," how could you check my claim?
Answer:
A solution to a linear equation means that the ordered pair is a point that lies on that line.
If someone were to say (2,5) is a solution to the equation y= 2x+3, you could check them by plugging in 2 where the variable "x" and seeing if y =5.
In this case,
y= 2(2)+3
y=7
(2,5) is not a solution.
