Answer:
30
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Given the 2 equations
4x + 3y = 16 → (1)
7x + 6y = 31 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the term in y
- 8x - 6y = - 32 → (3)
Add (2) and (3) term by term
- x = - 1 ( multiply both sides by - 1 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
4(1) + 3y = 16
4 + 3y = 16 ( subtract 4 from both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Solution is (1, 4 ) → B
Answer:
x<2
put a circle (unsahded) on number 2 and a line on all the sides to the left of 2 , like through 1, 0 , -1 ....
Step-by-step explanation:
4x<8
divide by 4
x<2
Answer : The expression which is equivalent to ![\sqrt[4]{9}^{\frac{1}{2}x}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B9%7D%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D)
is 
.
Step-by-step explanation :
The given expression is:
As we know that:
![\sqrt[4]{x} =x^{\frac{1}{4}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%7D%20%3Dx%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D)
So, by solving the above expression, we get:
By multiplying the power of 9, we get the following expression.
Hence, the expression which is equivalent to is .
On row 1, E is the wrong one because it should be 9n but its 8n instead
On row 2, P is the wrong one because it should be 6x but its 6+3x instead
On row 3, N is the wrong one because it should be 2x+2 but its 3x instead
On row 4, R is the wrong on because it should be 11a+3 but its 14a instead
On row 5, R is the wrong one because it should be 18n but its 9n instead
On row 6, M is the wrong one because it should be 15x+3 but its 15x+45 instead
On row 7, A is the wrong one because it should be 14t+4 but its 18t instead
On row 8, E is the wrong one because it should be 3n+21 but its 9+7n
