7s = 4
/7. /7
s= 4/7
thats the equation right?
The slope is [ 8 - (-1) ] / [ -1 - (-4) ] = 9 / 3 = 3;
The line has the equation: y - 8 = 3( x + 1);
y - 8 = 3x + 3;
y = 3x + 11.
Hello!
In order to find this out we should first know the ratio for the time and distance. So it takes her 4 minutes to go 2 blocks. So the ratio looks like this: 4:2. If we are trying to find 9 blocks, then multiply it by 4 and just add the other two minutes .
So in total your answer is: It takes Maya 18 minutes to walk 9 blocks.
I hope it helps!
Answer:
y≥1
Step-by-step explanation:
hello :
y-1≥0
y-1+1≥0+1
y≥1
First, we define variables:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23
Answer:
the coach did purchase 23 large hats
d. 23
