=3y-11, 4x-3y=-26 Substitution
Answer:
C
Step-by-step explanation:
The line on the left has equation y = x - 2
The start of the line has an open circle at x = 3 meaning that x ≠ 3
The line is defined as y = x - 2 for x < 3
The line on the right has equation y = x - 1
The start of the line has a closed circle at x = 3 meaning that x can equal 3
The line is defined as y = x - 1 for x ≥ 3
Thus the definition of the function is C
Z^2 - 2z - 35 = 0
(z - 7)(z + 5) = 0
z - 7 = 0
z = 7
z + 5 = 0
z = -5
solution is : z = 7,-5
Answer:
Exact form: 5/2
Decimal form: 2.5
Mixed number form: 2 and 1/2
Step-by-step explanation:
when you divide a fraction you keep, change, flip
Equation: 5/8 ÷ 1/4
keep 5/8 the same
change the divide symbol into a multipulcation symbol
flip 1/4 the other way, so it's 4/1 (it's a whole number now)
then just multiply across
Equation now: 5/8 × 4/1
