Answer:
y > 4
Step-by-step explanation:
2 (5y-4)>32
Divide each side by 2
2/2 (5y-4)>32/2
5y-4 > 16
Add 4 to each side
5y-4+4 > 16+4
5y > 20
Divide each side by 5
5y/5 > 20/5
y > 4
Step-by-step explanation:
2 (5y - 4) > 32
10y - 8 > 32 (by expanding)
10y> 32 + 8
10y> 40
Y > 40/10
Y=4

Answer:
Step-by-step explanation:
if m is the slope of given line.
Then eq. of parallel line through (-4,-6) is
y+6=m(x+4)
Answer:
y=-6
Step-by-step explanation:
The line shown is a horizontal line through the y-axis and has the equation y=4. A parallel line to it is a line that does not cross it. It will also have the form y=a where a is the y-coordinate of its points. The point (-4,-6) is on the line so y=-6 is the line.

the sum of four consecutive integers is 34. find the least of the numbers
Answer:
7
Step-by-step
n=smallest integer; n+1=second integer; n+2=third integer; n+3=fourth integer
n+(n+1)+(n+2)+(n+3)=34
4n+6=34
4n=28
n=7 ANSWER: The smallest integer is 7
CHECK:
7+8+9+10=34
34=34
the least of the four consecutive integers is 7.
Let's denote the four consecutive integers as x, x + 1, x + 2, and x + 3.
According to the given information, the sum of these four consecutive integers is 34:
x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) = 34
Simplifying the equation:
4 x + 6 = 34
Subtracting 6 from both sides:
4 x = 28
Dividing both sides by 4:
x = 7
The four numbers are 7, 8, 9, 10
Therefore, the least of the four consecutive integers is 7.

Step-by-step explanation:
Suppose a medium pizza at Vincent's costs $6.75 plus $0.75 for each topping, and the cost of a medium pizza at Original Italian Pizza is $6.15 plus $0.80 per topping. How many toppings would you have to include on your pizza for the price to be the same at both places?
Answer:
12 toppings
Step-by-step explanation:
To do this, we need to write an equation for each place, and then, equal both equations to solve for this.
Let's call "y" the price of the pizza, and "x" the number of toppings.
At Vincents, pizza costs 6.75 + 0.75 for each topping, so the equation here would be:
y = 6.75 + 0.75x (1)
Now, at italian pizza, a pizza costs 6.15 + 0.80 per topping, so the equation:
y = 6.15 + 0.80x (2)
Now, we don't need to know the actual price of the pizza, we only want to know how many toppings we need to add on both places, so the pizza has the same price. We have both equations, it's time to equal both of them:
Equalling (1) and (2) we have:
6.75 + 0.75x = 6.15 + 0.80x
Now, let's solve for x:
6.75 - 6.15 = 0.80x - 0.75x
0.6 = 0.05x
x = 0.6 / 0.05
x = 12
So the number of toppings to include in the pizza so the price is the same for both places, will have to be 12 toppings.
Answer:
12 toppings and the prize will be the same.
Step-by-step explanation:
Let
number of toppings = a
Medium pizza at Vincent's
cost = 6.75 + 0.75a
Medium pizza at Original Italian Pizza
cost = 6.15 + 0.80a
For the cost to be the same
6.75 + 0.75a = 6.15 + 0.80a
collect like terms
6.75 - 6.15 = 0.80a - 0.75a
0.6 = 0.05a
divide both sides by 0.05
a = 0.6/0.05
a = 12
12 toppings and the prize will be the same.

Which relationships could have a negative correlation? Select three options. number of hours on video games and test scores speed of a car and minimum stopping distance average running speed and total race time adult’s head circumference and age outside temperature and amount of a heating bill
Answer:
- number of hours on video games and test scores
- average running speed and total race time
- outside temperature and amount of a heating bill
Step-by-step explanation:
1. number of hours on video games and test scores (negative correlation - as you spend more hours on video games, test scores might decrease)
2. speed of a car and minimum stopping distance (positive correlation - as the distance to the next stop increases, the speed of the car should increase)
3. average running speed and total race time (negative correlation - as you run for longer, your speed should decrease)
4. adult’s head circumference and age (positive correlation - as your age increases, your head size increases, too)
5. outside temperature and amount of a heating bill (negative correlation - as temperature increases, the heating bill decreases)
The two options with negative correlations are:
"Number of hours on video games and test scores" and "Outside temperature and amount of a heating bill"
Which relationship could have a negative correlation?A relation between two variables, x and y, has a negative correlation when if one variable increases, the other decreases.
From the options, the ones that can have a negative correlation are:
Number of hours on video games and test scores: Here as the number of hours that you play video games increases, it is possible that your test scores decrease, so we have a negative correlation.
Outside temperature and amount of a heating bill: As the outside temperature decreases, the amount that you pay in heating increases, so again, we have a negative correlation.

A group of 6 students was asked, "How many hours did you watch television last week?" Here are their responses: 10, 5, 18, 9, 17, 12 Find the median and mean number of hours for these students. If necessary, round your answers to the nearest tenth.
Answer:
Mean = 11.8
Median = 11
Step-by-step explanation:
Here we are asked to calculate the median and the mean for these set of numbers
Let’s start with the mean
The mean refers to the average, we simply add all the numbers together and divide by their count.
That would be;
Arithmetic mean = (10+ 5 + 18 + 9 + 17 + 12)/6 = 71/6 = 11.833 which is 11.8 to the nearest tenth
To get the median, what we do is to first rearrange the values we have from the lower to the highest.
That would be;
5,9,10,12,,17,18
Looking at the numbers after rearranging, the two middle numbers we have are 10 and 12.
So we add these together divide by 2.
That would be (10+12)/2 = 22/2 = 11

If 30% of the students taking a module failed the practical test. The class has 130 students. How many students passed the test?
Answer:
91 students passed the test.
Step-by-step explanation:
130 / 10 = 13
13 x 3 = 39
130 - 39 = 91
Answer:
91 students passed the test.
Step-by-step explanation:
We need to find 10% of 130.
130÷10=13
Then we need to make it 30% in order to see the amount of students that failed the test.
13×3=39
Then we need to do 130 - 39 (The whole class- 30%)
130-39=91
Find the value of c (x-2) is a factor of the polynomial p(x). P(x)=x^3-4x^2+3x+c
Answer:
c = 2
Step-by-step explanation:
P(x)=x^3-4x^2+3x+c
The polynomial has x - 2 as a factor
Rewriting the polynomial as:
x^3-4x^2+3x+c = x^3 - 2x^2 - 2x^2 + 4x - x + c =x^2(x - 2) - 2x(x - 2) - (x - c)As we see the first 2 terms have (x -2) as a factor, so the third term:
(x - c) = (x - 2) c=2Answer is c= 2

For what value of x do the expressions 2/3 x+2 and 4/3 x-6 have the same value? *
Answer: 42
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
Hi, to answer this we have to equal both equations given and solve for x.
2/3x+2 = 4/3x-6
Solving for x:
2/3x-4/3x= -6-2
-2/3x = -8
x = -8/ (-2/3)
In conclusion, when the value of x is equal to 12, both expressions will have the same value.

Answer:
1) A profit of Rs 250 is made.
3) 11 marks
3) 14/15 kg
4) 15/28
Step-by-step explanation:
1) A profit of Rs.10 per bag of oranges and a loss of Rs.5 per bag of grapes sold. The total profit/loss from selling 200 bags of oranges and 350 bags of grapes is:
total profit/loss = 200 (10) - 5(350) = 2000 - 1750 = Rs 250
A profit of Rs 250 is made.
2) (+5) marks are given for every correct answer and (-3) marks are given for every incorrect answer and 0 for answer not attempted. If he answer 4 correct and 3 incorrect out of 7 questions. His score is:
Score = 5(4) - 3(3) = 20 - 9 = 11 marks
His score is 11 marks
3) An object weighs 28/5 kg on earth. Since its weight on moon is 1/6 its weight on Earth.
The weight on moon = 1/6 × 28/5 = 14/15 kg
4) 3/4 of 5/7 = 15/28
