Answer:
3a^2 - 6b + 2ab
Step-by-step explanation:
Put all the like terms together
(4a^2 - a^2) - (7b + b) + 2ab
then simplify
(4a^2 - a^2) = 3a^2
(-7b + b) = -6b
then rewrite
3a^2 - 6b + 2ab
Answer:
3a^2 - 6b + 2ab
Step-by-step explanation:
Add like terms together so shifting the equation a little to make it easier to add:
4a^2 - 7b + 2ab - a^2 + b
4a^2 - a^2 - 7b + b + 2ab
3a^2 - 6b + 2ab
Samantha claims that 4x + 2 is equivalent to the expression x + 17 + 3x − 15. Check whether Samantha’s equivalent expression is correct using x = 2. Samantha is incorrect because when using x = 2, the resulting values in both expressions are different. Samantha is incorrect because the expressions cannot be checked using x = 2. Samantha is correct because when using x = 2, the resulting values in both expressions are equal.

Write 67/18 as a decimal. If necessary, use a bar to indicate which digit or group of digits repeats
Answer:
67/18 is 3.72 as a decimal.
Step-by-step explanation:
I know this because, to turn a fraction into a decimal, you must divide the numerator by the denominator.
67 ÷ 18 = 3.72
Therefore, 3.72 is my answer.
Find the equation of the linear function represented by the table below in slope-intercept form.
Answer:
y= 8x +7
Step-by-step explanation:
slope-intercept form:
y= mx +c, where m is the gradient (or slope) and c is the y-intercept.
Since it is a linear function, the gradient of any 2 points would be equal.
[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]
Thus, gradient of the line
[tex] = \frac{39 - 23}{4 - 2} \\ = \frac{16}{2} \\ = 8[/tex]
Subst. m=8 into the equation:
y= 8x +c
To find the value of c, substitute a pair of coordinates.
When x=0, y= 7,
7= 8(0) +c
c= 7
Thus, the equation of the linear function is y= 8x +7.

I am having a hard time with simultaneous equations specifically the elimination method, i want to know when do we subtract and when do we add, so if u know how its done plz help im confused
Example :
3x-2y =7
4x+y = 13
Plz solve it too-
Answer:
The solution to these two equations is (3, 1)
Step-by-step explanation:
So for the elimination method, we are basically multiply each equation by a factor that would allow us to cancel them out..
We could rewrite the equations as the following to make the elimination method easier:
-2y + 3x = 7
y + 4x = 13
We could multiply the second equation by positive 2 in order to cancel out the y from the first equation when we add.
-2y + 3x = 7
2y + 8x = 26 ---> Now we have 11x = 33, when we simplify, we have x = 3.
Now to find our y value in order to find the solution, we would just plug in our x value and solve for y. **We can use either equation to find the answer for this...
-2y + 3x =7.
-2y + 3(3) = 7
-2y + 9 = 7
-2y = -2
y = 1.
We can double check our answer by plugging in both x and y values into the second equation.
4(3) + 1 = 13.
12 + 1 = 13, so we are correct.
The solution to these two equations is (3, 1)
Samuel can type nearly 40 words per minute. Use this information to find the number of hours it would take him to type 3.4 × 105 words. Samuel can type 3.4 × 105 words in hours and minutes.
Answer:
8.925 minutes or 0.14875 hours..?
Step-by-step explanation:
I feel like I'm missing something here... The 3.4 x 105 words seems off. Why didn't they just say 357 words?
Assuming that he types 40 WPM and they're looking for how long it would take for him to type 357 words:
[tex]3.4*105 = 357[/tex] words total
[tex]\frac{357}{40} = 8.925[/tex] minutes
[tex]\frac{8.925}{60} = 0.14875[/tex] hours

Solve 3q - 5 = 13 for q.
⇒ Answer:
[tex]q = 6[/tex]
⇒ Step-by-step explanation:
Lets solve!
[tex]3q -5 = 13[/tex]
⇒ First we add 5 to both sides.
[tex]3q -5 = 13[/tex]
[tex]+ 5[/tex] [tex]+ 5[/tex]
[tex]3q = 18[/tex]
⇒ Next we divide both sides by 3.
[tex]\frac{3q}{3} = \frac{18}{3}[/tex]
[tex]q = 6[/tex]
⇒Woohoo! Brainliest Appreciated! Hope I helped!
Answer:
q = 6
Step-by-step explanation:
To solve for q, isolate the variable.
3q - 5 = 13
Move -5 to the right side and perform the inverse operation. Since you were subtracting on the left, add on the right.
3q = 13 + 5
3q = 18
The last step is to isolate the variable by dividing 3 by 18. The reason you divide on the right is because you were multiplying on the left, and you need to perform the inverse operation.
q = [tex]\frac{18}{3}[/tex]
q = 6

Graph the equation
y-3=-3/2(x+4)
Answer: x = (-2,0) y = (0,-3) slope is -3/2
Step-by-step explanation: graph the line by using the slope and y intercept
The graph for the points (0, -3) and (2, -6) is plotted on the graph below.
The given equation is y-3= -3/2(x+4).
What is the graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.
Graph the line using the slope and y-intercept, or two points.
Slope: -3/2
y-intercept: (0, -3)
Plot the points (0, -3) and (2, -6) on the graph
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s): (−2,0)
y-intercept(s): (0,−3)
Therefore, the graph for the points (0, -3) and (2, -6) is plotted on the graph below.

Mary sees 40 elephants and 15 baby elephants at the zoo. What is the ratio of elephants to baby elephants?
Answer:
8:3
Step-by-step explanation:
You divide them both by 5.
Answer:
40:15 = 8:3
Step-by-step explanation:
This is the answer because:
1) Since there are 40 elephants and 15 baby elephants, the answer would be 40:15, but we want to simplify the ratio. In order to simplify the ratio, just divide each number by 5:
40 ÷ 5 = 8
15 ÷ 5 = 3
8:3
Therefore, the answer is 8:3.
