Answer:
Option a) f(x)=x^2
Step-by-step explanation:
The parent function that can be used to graph the function f(x)=-9(x+5)^2 is f(x)=x^2
Answer:
y=(-3/4)x-2
Step-by-step explanation:
slope intercept is y=mx+b
y--5=-3/4(x-4)
y+5=-(3/4)(x-4)
y+5=-(3/4)x-2
y=(-3/4)x-2
Answer:
12
Step-by-step explanation:
Hope this helps correct me if I'm incorrect
Erica earned a total of $50,450 last year from her two jobs. The amount she earned from her job at the store was $1,250 more than four times the amount she earned from her job at the college.
Lets x be the amount she earned from here job at college
amount she earned at the store = 4 * amount earned at college + 1250
= 4x + 1250
Amount earned at college + amount earned at store = 50450
x + 4x + 1250 = 50450
5x + 1250 = 50450
Subtract 1250 from both sides
5x = 49200 (divide by 5)
x = 9840
she earn $9840 from her job at the college
