Answer:
3/2
Step-by-step explanation:
● (-3/8) ÷(-1/4)
Flip the second fraction by putting 1 instead 4 and vice versa.
● (-3/8)* (-4/1)
-4 over 1 is -4 since dividing by 1 gives the same number.
● (-3/8)*(-4)
Eliminate the - signs in both fractions since multiplying two negative numbers by each other gives a positive number.
●( 3/8)*4
● (3*4/8)
8 is 2 times 4
● (3*4)/(4*2)
Simplify by eliminating 4 in the fraction.
● 3/2
The result is 3/2
Answer:
y = 5/2x - 7
Step-by-step explanation:
5x - 2y = 4
5x - 4 = 2y
y = 5/2x - 2
Slope = 5/2
Point (2,-2)
y-intercept: -2 - (5/2)(2) = -2 - 5
= -7
