Answer:
-8/5
Step-by-step explanation:
y values minus each other over x values minus each other
Answer:
-8/5 or -1.6
Step-by-step explanation:
the formula for slop is y2-y1/x2-x1
y2 is -2
y1 is 6
x2 is 1
x1 is -4
(-2-6)/(1+4)
(-8)/(5)
the slope is -8/5 or -1.6

1995. Were 57 million cats as pets in the U.S. By 2003this number was 61 millionWrite a linea model for the number of cats as pets. Then use the model to predict the number of cats as pets in 2015
Answer:
Cats as pet in 2015 = 6 million
Step-by-step explanation:
Given:
Cats as pet in 1995 = 57 million
Cats as pet in 2003 = 61 million
Find:
Cats as pet in 2015
Computation:
Difference in year = 2003 - 1995
Difference in year = 8 year
Difference in year = 2015 - 2003
Difference in year = 2015 - 2003
Difference in year = 12 year
Difference in number = 61 - 57
Difference in number = 4 million
So,
Cats as pet in 2015 = 4 million x [12/8]
Cats as pet in 2015 = 6 million

Answer:
i) The probability of getting 50 cent coin is 5/18, or approximately 28%
ii) To scale the numbers up to let us have 65 fifty cent coins, there would be a total of 234 coins
Step-by-step explanation:
We are told the probability of choosing ten and 20 cent coins, and from that we can work out the probability for the 50 cent coin. All we need to do is add up the other two probabilities and subtract them from 1.
[tex]p = 1 - (\frac{1}{3} + \frac{7}{18})\\p = 1 - (\frac{6}{18} + \frac{7}{18})\\p = 1 - \frac{13}{18}\\p = \frac{5}{18}\\[/tex]
So the chance of getting a 50 cent coin is five eighteenths, or approximately 28%
For the second question We are asked to find the total number of coins if there are 65 fifty cent coins. (I can't see the text below that, but presumably it's saying that the ratios will stay the same).
We can solve this by comparing the two ratios, with x as the total, and solving for x:
[tex]\frac{5}{18} = \frac{65}{x}\\5x = 65 * 18\\x = 13 * 18\\x = 234[/tex]
So to keep the same ratios and have 65 fifty cent coins, we would need a total of 234 coins.

What value of x is in the solution set of 2(3x – 1) > 4x – 6?
It could only be the following :
A. -10
B. -5
C. -1
D. -3
Answer:
-1
Step-by-step explanation:
Given the equation :
2(3x – 1) > 4x – 6
Open the bracket :
6x - 2 > 4x - 6
Collect like terms
6x - 4x > - 6 + 2
2x > - 4
Divide both sides by 2
2x /2 > - 4/2
x > - 2
Since x > - 2
-10, - 5, - 3 are all < - 2
Hence, the only option greater than - 2 is - 1

Chuck and Holly are saving money to buy a car. Chuck has $500 already and is going to save $100 a month. Holly has $1000 and plans on saving $50 a month. In the space to the left, write an equation that shows when Chuck and Holly will have the same amount of money. What is the equation
Answer:
10 months
Step-by-step explanation:
Step one
Given
Chuck has $500
Chuckle wants to save $100 monthly
Let the number of months be x
And the total be y
So
Y=500+100x--------1
Holy has $500
Chuckle wants to save $500 monthly
Let the number of months be x
And the total be y
So
Y=1000+50x--------2
Equate 1 and 2
500+100x=1000+50x
1000-500=100x-50x
500=50x
x=500/50
x=10

Answer:
negative 16
Step-by-step explanation:
the numbers skip by 20
Answer:
-4
Step-by-step explanation:
If you look at the table closely for the value of x decreases by 2 like the first value is 7 then it goes to 5 then it goes to 3 then to 1, and if you look at the values of y it decreases by 20 like the first number is 66 then 46 then 26 then 6.
But in the table it asks the missing value of y when x is 0 not -1 so for difference of 1 instead of the usual 2 in the pattern the value of y would decrease by 10 instead of 20 so 6-10 would be -4
so the missing value of y is -4
Jonah and his sister are going to the amusement park. They each purchase 2 tickets at $1.25 each. Then, they each get a soda for $3.50 a piece. How much did they spend all together?
Answer:
$12.00 all together.
Step-by-step explanation:
there is only 2 people him and his sister.
They both purchase 2 ticket for $1.25
so 4 tickets all together
1.25x4=$5
They they both get one soda for $3.50
$3.50+$3.50=$7
$7+$5=12
So they spent $12

At the school carnival, the soccer team sold hamburgers and hot dogs. A person buying one hamburger and one hot dog will spend $17.65. The soccer team sold 22 hamburgers and 39 hot dogs and made $511.55. How much does each item cost?
A. hamburger:$7.25, hot dog: $10.40
B. hamburger: $8.39, hot dog: $8.39
C. hamburger: $8.83, hot dog: $8.82
D. hamburger: $10.40, hot dog: $7.25
The cost of the hamburger and hot dog will be $10.4 and $7.25, respectively. Then the correct option is D.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
At the school carnival, the soccer team sold hamburgers and hot dogs. A person buying one hamburger and one hot dog will spend $17.65. The soccer team sold 22 hamburgers and 39 hot dogs and made $511.55.
Let x be the cost of hamburgers and y be the cost of hot dogs. Then the equation will be
x + y = 17.65 ...1
22x + 39y = 511.55 ...2
Solve the equations, then we have
22(17.65 - y) + 39y = 511.55
388.3 - 22y + 39y = 511.55
17y = 123.25
y = $7.25
Then the value of x will be
x + 7.25 = 17.65
x = 17.65 - 7.25
x = $10.40
The cost of the hamburger and hot dog will be $10.4 and $7.25, respectively. Then the correct option is D.

Answer:
x = 1.155
x = -1.155
Step-by-step explanation:
4x² = x² + 4
i) move variable to the left-hand side and change its sign4x² - x² = 4
ii) collect like terms3x² = 4
iii) divide both sides of the equation by 3[tex] \frac{ {3x}^{2} }{3} = \frac{4}{3} [/tex]

What is Distributive Property?The distributive property is also known as the distributive law of multiplication over addition and subtraction. The name itself signifies that the operation includes dividing or distributing something. The distributive law is applicable to addition and subtraction. Let us learn more about the distributive property in this page.
The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B - C) = AB - AC. This means operand A is distributed between the other two operands.
Given:
48 + 72
Now, factorize the above into prime factors
48 = 2 x 2 x 2 x 2 x 3
and, 72 = 2 x 2 x 2 x 3 x 3
Now, rewriting
48 + 72
= 2 x 2 x 2 x 2 x 3 + 2 x 2 x 2 x 3 x 3
= 2 x 2 x 2 x 3 (2 + 3)
=24 (2+3)
Hence, the expression can be written as 24 (2+3).
