Answer:
Step-by-step explanation:
So we are given two values:
They can be interpreted as: (4,9) and (-11,k).
So, we want to find the value of k such that the slope of the line between the two points would be 5.
Recall the slope formula. It is:
Let (4,9) be x₁ and y₁ and let (-11,k) be x₂ and y₂. Substitute 5 for m. Therefore:
Simplify the denominator:
Multiply both sides by -15. The right side cancels:
Now, add 9 to both sides. The right side cancels.
Therefore, k is -66.
Answer:
Siti bought 13 blue buttons
Step-by-step explanation:
for not to get confused, we are going to solve the problem step by step
Siti had 135 buttons
5/9 of the buttons were red and the rest were blue
let's calculate how many buttons were red out of 135
135 * 5/9 = 75
if 75 buttons were red and the rest were blue, we can calculate how many were blue
135 - 75 = 60
says she only use 64 red buttons
if we had 75 red buttons and she used 64
75 - 64 = 11
she tells us that she had 84 buttons left, from which we know she had 11 red buttons that had been left over and 60 blue ones that she did not use, so we can calculate how many blue buttons she bought since we have the total number of buttons that she has now
84 - 60 -11 = 13
Siti bought 13 blue buttons
