answer
C. 30
Answer:
- B. 2 x minus z minus 5 + 2 z squared
Step-by-step explanation:
<u>Conditions:</u>
- The x-term has a coefficient of 2,
- The z-term has a coefficient of -1.
- The expression has a constant term less than zero
<u>Answer options:</u>
A. 2 x + z + 5 minus 6 z squared ⇒ 2x +z+5-6z²
- Incorrect. Only the first condition is met
B. 2 x minus z minus 5 + 2 z squared ⇒ 2x-z-5+2z²
- Correct. All 3 conditions met
C. Negative 2 x minus z minus 5 + 2 z squared ⇒ -2x-z-5+2z²
- Incorrect. The first condition is not met
D. Negative 2 x + z minus 5 + 2 z squared ⇒ -2x+z-5+2z²
- Incorrect. Only the third condition met
Answer:
The numbers are 20 and - 13
Step-by-step explanation:
Given as ;
The sum of two numbers = 7
Two times a number and three times another number = 13
So ,Let The first number = x
and The second number = y
According to question
x + y = 7 and ...A
2 × x + 3 × y = 1 ....B
Multiply eq A by 2
I.e 2 × ( x + y ) = 2 × 7
Or, 2 × x + 2 × y = 14
Now solve the both equation
( 2 × x + 3 × y ) - ( 2 × x + 2 × y ) = 1 - 14
Or. ( 2 x - 2 x ) + ( 3 y - 2 y ) = - 13
Or, 0 + y = - 13
∴ y = - 13
Put The value of y in eq A
x + y = 7
Or , x = 7 - y
Or, x = 7 - ( - 13 )
so, x = 7 + 13
∴ x =20
Hence The numbers are 20 and - 13 Answer
X^2 x 8x -3x^2 +5 x 8x -5 x 3
8x^3 -3x^2 +40x -15
This is non linear
Because it is not a straight line
