Answer:
Step-by-step explanation:
Point slope form: y−7=34(x−3)
Slope intercept form: y=34x+194..or..y=34x+434
Explanation:
Since you have one point and the slope, you can use the point slope formula, then solve for y to get the slope intercept form, so that you can determine the y-intercept (b). Then you can graph the resulting equation.
Point slope formula
y−y1=m(x−x1), where x1,y1=(3,7), and m=34 is the slope.
Substitute the given values into the formula.
Answer:
x=(10,0)
y=(0,4)
Step-by-step explanation:
Rewrite the equation so it is 5y=2x-20
Multiply both sides by 5
Then figure out the equation and you get the x intercept
Then put 10 into your new equation in the x spot and thats how you get y
Hope this helps:)
If my explaining is not good you can also use Math_way and it shows you all th steps too.
Answer:
P = $2448.89
P ~= $2,449
He need to deposit $2,449
Step-by-step explanation:
Given:
Interest rate r= 7% = 0.07
Number of years n = 3 years
Future value that should be meet A = $3000
We need to calculate the initial investment (Principal P). Using the compound interest formula:
A = P(1+r)^n
P = A/(1+r)^n
Substituting the values of A, r, n, we have;
P = 3000/(1+0.07)^3
P = $2448.89
P ~= $2,449
Answer:
B.

Step-by-step explanation:
5x - 3 = y then 5x = y + 3 then x = (y + 3)/5
then the inverse function of f is : (x+3)/5
