Answer:
The second and third answers are correct.
Step-by-step explanation:
This is a upwards opening parabola. It has no maximum. It has a minimum at ( 1,-4).
The first answers is incorrect.
A function is increasing when it goes up. It is increasing from 1 to the right or when x>1 . It is also increasing from - infinity to 1 so x <1
The second answer is correct.
The y intercept is where it crosses the y axis. This is at the point x = -2
The third answer is correct.
All points on a graph are solutions to the function. If the function is set equal to zero, then this has two real zeros.
The fourth answer is false.
A constant rate of change means that it is linear. This is a parabola. A parabola increases as x^2 not x, so it is not a constant rate of change
The fifth answer is not correct.
The range is the values that y can take.This says y must be less than or equal to -4. That is not true. y≥ -4.
The sixth answer is not correct.
Answer:
yes
Step-by-step explanation:
Because 4/3=4*4/3*4=16/12
Answer: 91/288
Step-by-step explanation: To divide mixed numbers, first write the mixed numbers as improper fractions.
We can do this by multiplying the denominator by the whole number and then adding the numerator. Then, we put our new numerator over our old denominator.
So here, we can write 1 and 5/8 as the improper fraction 13/8 and we can write 5 and 1/7 as the improper fraction 36/7.
So here, we have 13/8 ÷ 36/7.
Dividing by a fraction is the same as multiplying by the reciprocal of that fraction.
So here, 13/8 ÷ 36/7 is the same as 13/8 × 7/36.
So now we are simply multiplying fractions and we do this by multiplying across the numerators and multiply across the denominators.
So now we have 91/288 which is in lowest terms.
This means that 1 and 5/8 divided by 5 and 1/7 is 91/288.
Answer:
3/5
Step-by-step explanation:
The question is incomplete. Let us use this as the complete version;
<em>Of the people at a tennis club 2/5 are women. The rest of the people are men. What fraction of the people are men?</em>
<em />
Let the total people be 1
Given
Fraction that are women = 2/5
Fraction that are men = 1 - 2/5
Fraction that are men = (5-2)/5
Fraction that are men = 3/5
