Answer:
Step-by-step explanation:
Given equation of line is:
y = -4x+9
Comparing it with the standard form
y = mx+b
m = -4
As we know that the product of slopes of perpendicular lines is -1
Let m1 be the slope of perpendicular line
m * m1 = -1
-4 * m1 = -1
m1 = -1/-4
m1 = 1/4
In order to find the value of b, putting the point in standard form
5 = (1/4)*4 + b
5 = 1 + b
b = 5-1
b = 4
Putting the value of b and m1 in standard form

Answer:
8 1/2 hrs/wk
Step-by-step explanation:
3(1 1/2 hrs) plus
2(1 1/4 hrs) plus
2(3/4 hr)
The LCD here is 4. Convert 3(1 1/2 hrs) to 3(1 2/4 hrs), so that we now have:
3(1 2/4 hrs) = 3 6/4 hrs
+2(1 1/4 hrs) = 2 2/4 hrs
+2(3/4 hrs) = 6/4 hrs
-------------------------------------
5 14/4 hrs, or
5 + 3 2/4 hrs, or
8 1/2 hours/week
It’s 28 because if 2 + 2 = your adopted then it’s 28
The appropriate numbers to fill in the magic squares are;
Row 2, Column 2 = 21/133
Row 2, Column 3 = 24/38
Row 3, Column 2 = 70/95
Row 3, Column 3 = 25/95
<h3>How to use magic squares?</h3>
To solve this magic square, we will follow the procedures below;
- Step 1; Convert all the numbers into lowest forms.
- Step 2; Find the sum of any column or row which is 34/19.
- Step 3; Put the numbers given in such positions that the sum of each row, column and diagonal is equal.
- Step 4; Write the numbers in their original form.
When we follow those steps above, we will arrive at the following figures;
Row 2, Column 2 = 21/133
Row 2, Column 3 = 24/38
Row 3, Column 2 = 70/95
Row 3, Column 3 = 25/95

Step-by-step explanation:
Let m be the price of 1 baby mice
Let p be the price of 1 baby python
Given,
as equation 1.
and
as equation 2
From here we can easily use elimination method
for solving simultaneous equations.
Use Equation 1 - equation 2 to eliminate m to find p.
Substitute p into equation 1.
therefore 1 baby mice cost $4.50 and 1 baby python costs $45.
