Answer:
7 months
Step-by-step explanation:
He plans on depositing $200 every month into the savings account that already has $600 in it.
We can represent the amount of money he will have after a certain number of months (x) as:
A = 600 + 200x
He needs to save $2000. Therefore, to find the months he needs to save, we need to find x when A is $2000:
2000 = 600 + 200x
200x = 2000 - 600
200x = 1400
x = 1400/200 = 7 months
He needs to save for 7 months.
Preston have to get some correct and some incorrect answers.
1.) False
2.) True
1.) a dotted line infers that any ordered pair that comes after the line is true. Ordered pairs that fall on the line will falsify the inequality.
2.) With solid line graphed inequalities, and ordered pair on the line OR in the shaded region makes the inequality true.
<span>d=420-65t. Geometric figure: Straight Line. Slope = -0.031/2.000 = -0.015; d-intercept = 420/1 = 420.00000; t-intercept = 420/65 = 84/13 = 6.46154. Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : d-(420-65*t)=0.</span>
multiplication is for example 10×500=5,000
division is for example 5,000÷10=500
