Hey there!
In order to solve this problem, we can use the slope given two points formula:
y2-y1/x2-x1
Now, we can plug in our points to get:
1-0/5-0 = 1/5
Your answer is 1/5, or B.
Hope this helps!
Answer:
$40.92
Step-by-step explanation:
child ticket = $4.99 per kid
adult ticket = $5.99
we are told that Jenni has 7 kids she wants to take to the water park. we can multiply 4.99 × 7 to get the total cost of the 7 kids
4.99 × 7 = $34.93
we are also told that Jenni herself wants to go to the water park. since there is only 1 adult going (jenni) we can add $5.99 to our total for the 7 kids
$34.93 + $5.99 = $40.92
it would be $40.92 for Jenni to go to the waterpark with her 7 kids
this problem can also be expressed as an algebraic expression:
4.99x + 5.99 when x = 7
Answer:
I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:
5(-2)(2) = ?
-10 x 2 = ?
? = -20
-20 ≠ 20
Step-by-step explanation:
Justificaiton:
5(x)(2) = 20
10(x) = 20
10/10(x) = 20/10
x = 2
Second Justification:
5(x)(2) = 20
5/5(x)(2) = 20/5
2x = 4
2x/2 = 4/2
x = 2
Answer:
-4
Step-by-step explanation:
Wehn dealing with order of operations, we can remember the expression PEMDAS, which stands for parentheses, exponents, multiplication, division, addition, and subtraction.
So, our first step in the above problem is the parentheses:
The second step is exponents:
The third step is multiplication:
The fourth and final step is addition:
