3x -(-2-4x)=
What does this equals??
Answer:
7x + 2
Step-by-step explanation:
Original Equation: 3x − ( −2 − 4x)
First, we distribute the negative sign:
= 3x + (−1) (−2−4x)
=3x + (−1)(−2) + (−1)(−4x)
= 3x + 2 + 4x
Using the communitive property of addition, we can write:
= 3x + 4x + 2 (Instead of 3x + 2 + 4x)
Combining like terms, we get:
= (3x + 4x) + 2
= 7x + 2
Solve for x

Answer:
34.06°
Step-by-step explanation:
25 is the length of the hypotenuse side and 14 is the length of the opposite side.
Therefore, you will need to use sine to work out the missing angle.
sinx = opp / hyp
sinx = 14 / 25
x = sin ^ -1 (14 / 25)
= 34.06°

Step-by-step explanation:
The quotient of a number and 6 minus -1/3 is equal to the quotient of the number and 8. What is the number?
Answer:
x = 8
Step-by-step explanation:
Let the number = x
x/6 - 1/3 = x/8
-1/3 = x/8 - x/6
-1/3 = (6x-8x)/48
-1/3 = -2/48x
Divide both sides by -2/48
x = -1/3 ÷ -2/48
= -1/3 × -48/2
= 48/6
= 8
x = 8
The number = 8
A student performed the following steps to find the solution to the equation
X2 - 2x - 8 = 0. Where did the student go wrong?
Step 1. Factor the polynomial into (x - 4) and (x - 2)
Step 2. X-4 = 0 and x - 2 = 0
Step 3. x = 4 and x = 2
A. in Step 2
B. in Step 1
C. The student did not make any mistakes, the solution is correct
D. in Step 3
Answer:(b) step 1
Step-by-step explanation:
The wrong step in the student's workings is step 1
How to determine the wrong step?The equation is given as:
x^2 - 2x - 8 = 0
Expand the equation
x^2 + 2x - 4x - 8 = 0
Factorize the equation
x(x + 2)- 4(x + 2)
Factor out x + 2
(x - 4)(x + 2) = 0
The above means that the factored equation of x^2 - 2x - 8 = 0 is (x - 4)(x + 2) = 0
This means that the step 1 of the student's step is wrong and incorrect

PLZ HELP IM BEGGING
Answer:
-x+y= -14 (get this equation to where you can easily plug it in for a variable)
y= x -14
5x +6y =26 (plug the value above in for y and then solve)
5x + 6 (x-14) = 26 (use the distributive property)
5x +6x - 84 = 26 (combine like terms on the left side)
11x - 84 =26 (add 84 to both sides)
11x = 110 (divide both sides by 11 to isolate the x-variable)
x= 10 (this is the value for x. plug it into the easier equation and solve)
-(10) +y = -14
y= -4
(10, -4) (this is the solution for the system of equations)

please hellp find x y and z
Answer:
angle x = 98
angle y = 82
angle z = 82
Step-by-step explanation:
angle y + 98 = 180; therefore, angle y = 82 degrees
angles z and y are alternate interior angles and are congruent (equal)
angle x is 98 degrees because angles x and y are same-side interior and their angles are supplementary (add up to 180 degrees)
Challenge The numbers of home runs a baseball player hits during spring training and during the regular season for four years are shown. Decide if the relationship between home runs hit in spring training and during the regular season is proportional. If the table represents a proportional relationship, find how many home runs are hit during the regular season if the player hit 3 during spring training
Answer:
12
Step-by-step explanation:
Key word: Most likely
First try to find the constant of proportionality
8/2= 4
4/4= 1
20/5=4
24/6=4
Since it says most likely we would say the constant of proportionality is 4.
Since they are asking for 3 homes runs we will do 3 times 4
[tex]3[/tex]×[tex]4=12[/tex]
The player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.
What is constant of proportionality?The constant of proportionality is the ratio between two directly proportional quantities.
Two quantities are directly proportional when they increase and decrease at the same rate.
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Finding the constant of proportionality :-
8/2= 4
4/16= 4
20/5=4
24/6=4
Since, the constant of proportionality is 4.
And, they are asking for 3 homes runs we will do 3 times 4
Therefore, 3 x 4 = 12
Hence, the player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.

What is the value of x in the solution to the system of equations below?
15x - 12y = 13
30x + 9y = 4
Answer:
1/3
Step-by-step explanation:
Use the elimination method.
15x - 12y = 13
30x + 9y = 4
If you add both equations you will not cancel out any variables, so you need to multiply one of the equations by something. Multiply the first equation by -2 to cancel out the x values.
-2(15x - 12y = 13)
30x + 9y = 4
You should have these two equations now:
-30x + 24y = -26
30x + 9y = 4
Add them together now. You should get this now.
33y = -22
Divide both sides by 33. You should get y = -2/3
Now, substitute the y value into any of the two equations that you started with. Let's substitute the y value for the second equation.
30x + 9 (-2/3) = 4
30x - 6 = 4
30x = 10
30 30 (divide 30 and 10 by 30)
x = 1/3
