.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]

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

7 less than 4 times a number equals 13
Answer:
X = 5
Step-by-step explanation:
4x - 7 = 13
4x = 13 + 7
4x = 20
x = 20 / 4
x = 5
Hope it Helps :) !!
The solution of the given equation will be; X = 5
We know that the equation is defined as an expression that shows the relationship between two or more numbers and variables.
WE are given the statement as;
"7 less than 4 times a number equals 13 "
The equation becomes as;
4x - 7 = 13
Now solving for x;
4x = 13 + 7
4x = 20
Divide;
x = 20 / 4
x = 5
The value of x will be; x = 5

what is 2/3+1/4 i need help
Answer:
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.

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.

w is greater than or equal to – 7.
W is no more than 7
w is no less than - 7
w is at least - 7
w is no more than 7 is different
Answer:
W is no more than 7
Step-by-step explanation:
W is greater than or equal to -7 is (W>_-7)
W is no more than 7 is (W<_7)
W is no less than -7 is (W>_7)
W is at least -7 is (W>_7)
Out of all of these, w is no more than 7 is the only different expression

simplify
−2(j^2− k) − 6(j^2 + 3k )
Answer:-8j^2-16k
Step-by-step explanation:
First step:-2j^2-(-2)k=-2j^2+2k
Second step:
-6(j^2+3k) use the formula a(b+c)=ab + ac
a=-6 b=j^2 c=3k
-6j^2+(-6).3k
-6j^2-6.3k=-6j^2-18k because we multiplied 6x3=18
So we gather the whole equation And simplify
-2j^2+2k-6j^2-18k
-2j^2-6j^2 +2k-18k(add like terms)6+2=8
-8j^2+2k-18K (subtract Like terms 18-2=16)
And the answer will give -8j^2-16k

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]

Which of the following are appropriate names for the angle composed of the rays JK−→− and JL−→? Select the three correct answers.
A. Angle JKL
B. KJL
C. L
D. K
E. J
F. LJK
Answer: KJL, LJK and ∠J
Step-by-step explanation:
We have two rays.
JK and JL.
So the common point of bot rays is the point J.
In the angle notation, we usually write the common point in the middle.
So the possible notations for this angle are:
LJK or KJL.
Also knowing that the vertex of the angle is at the point J, we also could call this angle as:
∠J.
So the correct options are B, F and i suppose that the option D is actually ∠J (you wrote that the option D is only J)
