Answer:
$2
Step-by-step explanation:
Sandy adds $4 to a certain amount of money she already has saved.
Let the amount she has saved be x.
=> x + 4
Kyle already has 10 times as much money as sandy has saved (10x) but then spends 14$ dollars of his savings.
=> 10x - 14
They both have the same amount of money now:
=> 10x - 14 = x + 4
To get x, collect like terms and simplify:
10x - x = 4 + 14
9x = 18
x = 18 / 9 = $2
This means that Sandy had already saved $2.
Answer with explanation:
--------------------------------------------------------Dividing both sides by 8 x
This Integration is of the form ⇒y'+p y=q,which is Linear differential equation.
Integrating Factor
Multiplying both sides by Integrating Factor
When , x=1, gives , y=9.
Evaluate the value of C and substitute in the equation 1.
Answer:
y = -0.6x^2 + 5x + 6
Step-by-step explanation:
First, find the equation of a linear line that passes through the points (0,6) and (3, 15.6) in the slope intercept form, y = mx + b. We know that the line has a y-intercept of 6, so b = 6. Substitute 3 for x, 15.6 for y, and 6 for b to find m.
y = mx + b
15.6 = 3m + 6
9.6 = 3m
m = 3.2
y = 3.2x + 6
y = a(x - 0)(x - 3) + 3.2x + 6
y = a(x)(x - 3) + 3.2x + 6
Finally, substitute 10 for x and -4 for y in the equation above to find a.
-4 = a(10)(10 - 3) + 3.2*10 + 6
-4 = a(10)(7) + 32 + 6
-4 = 70a + 38
-42 = 70a
a = -0.6
Simplify to write in standard form.
y = -0.6(x)(x - 3) + 3.2x + 6
y = -0.6x^2 + 5x + 6
Answer:
C
Step-by-step explanation:
Find 120% of 150
1.2 x 150 = 180
Increase to 150
180 + 150 = 330
