Answer:
-2
Step-by-step explanation:
The slope (or gradient) is the coefficient for x in a linear equation. It's calculated by the change in y divided by the change in x. In this case, the change in y is -2 and the change in x is 1, therefore the slope is -2/1 which is -2.

Convert to a decimal by dividing the numerator by the denominator.
0.916...I
Answer:
11/12
Step-by-step explanation:
First you convert both fractions to a common denominator, usually found by multiplying the denominators you have, i.e., 3*4=12. So let's convert to /12:
2/3 = 8/12 (times 4)
1/4 = 3/12 (times 3)
Now you can add them:
8/12 + 3/12 = 11/12
This cannot be simplified, so this is your answer.
Which characteristic of a data set makes a linear regression model unreasonable? a slope close to 0 a correlation coefficient close to 0 a slope close to –1 a correlation coefficient close to –1
Answer:
A correlation coefficient close to zero
Step-by-step explanation:
This makes linear regression unreasonable because the correlation coefficient shows how related the data points are, -1 and 1 being very strong and 0 being uncorrelated. So the line of best fit would not make sense because the data points are random in relation to one another.
Answer: B. A correlation coefficient close to zero

Britney bought 4 apples, 5 bananas, and 8 oranges at the grocery store. Which is the ratio of apples to bananas written as a decimal? A. 2 B. 0.5 C. 0.4 D. 0.8
Answer:
D. 0.8
Step-by-step explanation:
The ratio in mathematics indicates how many times one number contains another. To find this ratio you must make division of both nubers. For example the ratio of X to Y is X/Y.
As there are 4 apples to 5 bananas, the ratio of apples to bananas is:
4/5 = 0.8
Right answer is:
D. 0.8can someone simplify this for me please

The graph of the function f(x)=x2 will be translated 3 units up and 1 unit left. What is the resulting function g(x)
When a function is translated, it means the function is moved from one point to another.
The resulting function g(x) is: [tex]g(x) = (x + 1)^2 + 3[/tex]
Given that:
[tex]f(x) = x^2[/tex]
When the function is translated 3 units up, the rule is:
[tex](x,y) \to (x,y+3)[/tex]
So, we have:
[tex]f'(x) = x^2 + 3[/tex]
When the function is translated 1 unit left, the rule is:
[tex](x,y) \to (x + 1,y)[/tex]
So, we have:
[tex]g(x) = (x + 1)^2 + 3[/tex]
Hence, the resulting function g(x) is:
[tex]g(x) = (x + 1)^2 + 3[/tex]

.5(4x - 2) - 2(3x + 3) = 9 + 2(x+ 4)
Answer:
[tex]x = -4[/tex]
Step-by-step explanation:
To solve this equation, we need to apply the distributive property, combine like terms, and get x on one side of the equation.
First, let's apply the distributive property to all parts of the equation:
[tex]0.5(4x-2) - 2(3x+3) = 9+2x + 8[/tex]
[tex]2x - 1 - 6x - 6 = 9 + 2x + 8[/tex]
Combine like terms:
[tex]-4x - 7 = 2x + 17[/tex]
Add 4x to both sides:
[tex]-7 = 6x + 17[/tex]
Add -7 to both sides:
[tex]0 = 6x + 24[/tex]
Subtract 24 from both sides:
[tex]6x = -24[/tex]
Divide both sides by 6:
[tex]x = -4[/tex]
