5a-2b = 0
2a-3b = -11
Answer:
a=2
b=5
Step-by-step explanation:
5a=2b
a=2/5b
2(2/5b) -3b= -11
4/5b-3b =-11
-2.2b=-11
b=5
5a=2*5=10

How do I Determine whether Rollie's theorem can be applied to F on the closed interval (AB) F of X = -x squared
Answer:
See Explanation
Step-by-step explanation:
Your question is incomplete. I will take the complete question as:
[tex]f(x) = -x^2[/tex]
[tex]Interval: [-1,1][/tex]
Required
Determine whether Rollie's theorem can be applied or not
First, find the coordinates of the endpoints on the closed interval [-1, 1]
[tex]f(x) = -x^2[/tex]
[tex]f(-1) = -(-1)^2 = -1[/tex] ------ [tex](-1,-1)[/tex]
[tex]f(1) = -(1)^2 =-1[/tex] ---- [tex](1,-1)[/tex]
Find the derivative of f(x)
[tex]f(x) = -x^2[/tex]
[tex]f'(x) = -2x[/tex]
Calculate the slope (m) of the secant line i.e. [tex](-1,-1)[/tex] and [tex](1,-1)[/tex]
[tex]m = \frac{-1 - (-1)}{1 - (-1)}[/tex]
[tex]m = \frac{-1 +1}{1 +1}[/tex]
[tex]m = \frac{0}{2}[/tex]
[tex]m=0[/tex]
Set the derivative to the calculated slope:
[tex]f'(x) = m[/tex]
[tex]-2x = 0[/tex]
[tex]x=0[/tex]
Plug in 0 for x in f'(0)
[tex]f'(x) = -2x[/tex]
[tex]f'(0) = -2 * 0[/tex]
[tex]f'(0) = 0[/tex]
Since f'(0) is differentiable at x = 0. We can conclude that Rollie's theorem can be applied

Answer:
The first box in the girl row is 18, the second one in the boy row is 8, and the bottom one is also 18.
Step-by-step explanation:
To get 81 to 9, you have to divide by 9, which means you have to do the same to 72. You get the ration 9 to 8, 9 being girls and 8 being guys. Then to get from 8 guys to 16, you have to multiply by 2, which means you do the same to 9 and get the answer of 18 girls. Hope this helps :)

what equation is equal to: 5x-(9-6x)
Answer:
x = 9
Step-by-step explanation:
Move all terms containing x to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + -1x = 0 + -9
Combine like terms: 9 + -9 = 0
0 + -1x = 0 + -9
-1x = 0 + -9
Combine like terms: 0 + -9 = -9
-1x = -9
Divide each side by '-1'.
x = 9

Answer:
400%
Step-by-step explanation:
Original wieght = 12
New weight = 60
Change = 60- 12= 48
Change percent = change / original x 100 = 48 / 12 x 100 = 400 %

The difference of a number and - 11/12 is the same as the difference of three times the number and 1/6
Answer:
The number is 13 /24
Step-by-step explanation:
Let the number = x
x - (- 11/12) = 3x - 1/6
x + 11/12 = 3x - 1/6
Collect like terms ;
x - 3x = - 1/6 - 11/12
-2x = (-2 - 11) / 12
-2x = - 13 / 12
-2x(12) = - 13
-24x = - 13
x = 13 / 24

four times two less than a number is the same as thrice one more than the number. find the number
Answer:
11
Step-by-step explanation:
4 times 2 less than the number is equal to 4 * (x-2).
3 * one more than the number is equal to 3 * (x+1).
you get 4 * (x-2) = 3 * (x+1).
distribute the multiplication on each side of the equation to get:
4x - 8 = 3x + 3
subtract 3x from both sides of the equation and add 8 to both sides of the equation to get: 4x - 3x = 3 + 8
combine like terms to get x = 11.
that's your solution.
4 * (x-2) is equal to 4 * (11 - 2) which is equal to 4 * 9 which is equal to 36.
3 * (x+1) is equal to 3 * (11 + 10 which is equal to 3 * 12 which is equal to 36.
your solution is that the number is equal to 11!
what is the surface area of the 3- dimensional shape 3 ft 3 ft 3 ft
A. 24 Square feet
B. 72 Square feet
C. 198 Square feet
D. 216 Square feet
Answer:
c. 198 square feet
Step-by-step explanation:
Based on the picture I'm thinking the length of each line segment is 3ft, so each 'tile' on the surface of the figure is 9sqft.
Looking at the figure from the front and back you would see 4 tiles from each direction, same from the top and bottom (so far we have front + back + top + bottom = 4 + 4 + 4 + 4 = 16 tiles)
Looking directly from either side you would see 3 tiles each way, for 6 more tiles total, so the total number of tiles covering the figure is 16 + 6 = 22 tiles
Each tile is 9sqft, so total area is 22(9) = 198 sqft
Seven less than the product of 6 and a number is equal to 8 translates to an equation
Answer:
Answer: No it isn't an equation. Not yet at least.
Step-by-step explanation:
Yes it might well do, but if it does, it needs something on the other side of wherever you put the equal sign.
6x - 7 is all you have so far and you have no idea what comes next. As it is, what you wrote is an algebraic expression.
Pour teacher has disabled instant marking. Your marks will appear after the due date.
y is inversely proportional to x.
When y = 7, x = 9
a) Work out an equation connecting y and x.
b) Work out the value of y when x = 21.
How do i find k?
Answer:
a) y = 63/x
b) y = 3
Step-by-step explanation:
Inverse proportionality between two variables means that if one of them increases, then the other one decreases.
These type of relationships can be written as:
y = k/x
Now we know that when y =7, x = 9
Then we can replace these two values and find the value of k.
7 =k/9
7*9 = k
63 = k
The our relationship is:
y = 63/x
This is the solution to a).
Now let's go with b)
We want to find the value of y when x = 21. then we just need to replace x by 21 in the equation "y = 63/x"
We will get:
y = 63/21 = 3
When x = 21, y is equal to 3.
