Answer: John has 52 marbles in his collection
Step-by-step explanation:
Step 1
LET The number of marbles in John's collection can be represented by x. The and the number of marbles in Erica collection can be represented as =4x+ 10
The total number of marbles in both collections is 270 such that the expression to solve the equation will be
JOHN + ERICA = 270marbles
X + 4X+ 10= 270
Step 2--- solving
X + 4X+ 10= 270
5X+ 10= 270
5X= 270-10
5X= 260
X= 260/5
=52
John has 52 marbles in his collection
Erica has 4x + 10 = 4x 52 + 10=218 marbles

Answer:
y-int: (0, -45)
x-int: (-10, 0)
Step-by-step explanation:
x-intercept is the x-value when y = 0
y-intercept is the y-value when x = 0
x-int:
When y = 0, x = -10, so (-10, 0)
y-in:
when x = 0, y = -45, so (0, -45)
