Question 18
The answer is 4 days. 
Because, 
Kevin =3×n
Anita =4+ (2×n)
Equating the two equations. 
3n=4+2n
3n-2n=4
n=4

Question 19
When the solution is (4,1), it means the value of y=1 and x=4. 
The answer is;
y=x-3
y=-3x+13. Since when the values of x and y are substituted they satisfy the system. 

Question 20
The system has no solution.
This is because the line are parallel and they do not intersect to give a solution.

Question 6(Multiple Choice Worth 1 points)
Dafna11 [192]

Answer:

O The value of f(2) is smaller than the value of f(1).

Step-by-step explanation:

First, let's solve for both. When the problem says f(1) or f(2), this just means that the x value is equal to that. So:
f(1) = -5(1)^2 + 2(1) + 9 = 6
f(2) = -5(2)^2 + 2(2) + 9 = -7
Since f(1) = 6 and f(2) = -7, we know that f(1) is greater than f(2). Therefore, the value of f(2) is smaller than the value of f(1)

Can you solve the inequality 2(x-3) is less than or equal to 10 without using the distributive property? Explain.
STatiana [176]

Answer:

Yes, without using the distributive property, we get the value for the given expression 2(x - 3)  ≤ 10  as   x ≤ 8

Step-by-step explanation:

Here, the given expression is:

2(x - 3)  ≤ 10

Yes, the given expression can be solved without using the DISTRIBUTIVE Property

Here, consider the given expression:

2(x - 3)  ≤ 10

Now, divide the  inequality by 2 on both sides, we get:

\frac{2(x-3)}{2}  \leq  \frac{10}{2}\\\implies (x - 3)  \leq 5

Now adding (+3) on both the sides, we get:

(x - 3)  ≤ 5    ⇒  (x - 3  + 3 )  ≤ 5 + 3  

or, x ≤ 8

Hence, without using the distributive property, we get the value of x ≤ 8 for the given expression 2(x - 3)  ≤ 10

What is the hypotenuse?<br><br> legs are 10 and 11
Anit [1.1K]
Hey!

You have to use the Pythagorean Theorem

a² + b² = c²

a = 10
10² = 10 × 10 = 100

b = 11
11² = 11 × 11 = 121

100 + 121 = 221

√221 = 14.9(rounded)

Answer ⇒ 14.9

Hope this helps! :)
