Using the quadratic equation we get:
Factoring out 2 we get
Factoring out the imaginary number:
So b.
Answer:
y=-4x+7
Step-by-step explanation:
You put the points on a graph in desmos and then in a new line put the y=-4x+ and Playa round with numbers until you hit the point
Answer:
Step-by-step explanation:
A dependent variable in an expression is one whose value can be determined only when the value of other variable (i.e independent) is known.
A. The cost at the fitness center depends on the number of months (x).
The cost is the dependent variable, and number of months (x) is the independent variable.
f(x) = 100 + 40x
Example, the cost paid for 12 months can be determined as;
f(12) = 100 + 40(12)
= 100 + 480
= 580
Thus, $580 would be paid for 12 months at the fitness center.
B. The lettuce is sold at $1.69 per pound. The cost depends on the number of pounds of lettuce bought.
The cost is the dependent variable, while the number of pounds of lettuce (x) bought is the independent variable.
So that;
f(x) = 1.69x
The cost of 10 pounds of lettuce can be determined as;
f(x) = 1.69(10)
= 16.9
Thus, the cost of 10 lb of lettuce is $16.90.
Hi there.
The best way to estimate starts by rounding.
31.9 rounds up to 32.
32/4 = 8
The best estimate for 31.9 divided by 4 is 8.
