Lets use 1 to solve this problem because it is easiest to show.
Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3).
Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)
Therefore the page had a 9% reduction from its original size or is 91% of its original size.
Answer:
minimum
Step-by-step explanation:
Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
Whether the function is maximum or minimum can be determined by consideration of the sign of the coefficient a
• If a > 0 then minimum
• If a < 0 then maximum
For y = - 4 + 3x² the value of a is 3 > 0
Hence y = - 4 + 3x² is a minimum
Answer:
The correct options are 1, 2, 4 and 6.
Step-by-step explanation:
The given expression is
To subtract like term subtract like terms, subtract the coefficients, not the variables.
Therefore option 1 is correct.
Like terms are terms that contain the same variable, raised to the same power. For example: 3xy and 5xy, 4x² and 3x².
Therefore, option 2 is correct.
Using distributive property we get
Only combine terms which contain the same variable.
Therefore option 4 is correct.
The simplified expression is -4x-3y+3z. Therefore option 6 is correct.
Since this is a right triangle, use the Pythagorean Theorem to find c.
Pythagorean Theorem ⇒ a² + b² = c², where a and b are the legs and c is the hypotenuse.
Plug in 10 and 24 for the legs and c for the hypotenuse.
10² + 24² = c²
100 + 576 = 676
√676 = 26
c = 26
