7 0

Answer:

Sacing 490 spending 420

Step-by-step explanation:

If a is a fraction

Saving 7a Spending 6a

7a + 6a = 910

13a = 910

a = 910/13

a = 70

Saving 7×70 = 490

Spending 6×70 = 420

The sum is 490 + 420 is equal to 910

Find a formula for the function f(x) such that f′(x)=(ln(x))^2/x and f(2)=6
Rzqust [24]
F(x)= ∫ln²x/x dx= ∫ln²xd(lnx) cause d(lnx)= (lnx)'dx=1/x dx
= ln³x/3 +C with C is constant
In addition, we have f(2)=6, so we have 6=ln³2/3+C
or C= 6- <span>ln³2/3
And f(x)= </span>ln³x/3+ <span> 6- </span><span>ln³2/3</span>

Solve each system of equation for 3y+x=3 and -2y+5x=15
madam [21]

Answer:

<em>x = 3 and y = 0</em>

Step-by-step explanation:

3y+x=3

-2y+5x=15

Isolate y in 3y + x = 3 :

y= \frac{3-x}{3}

Substitute y = \frac{3-x}{3}  in -2y + 5x = 15 :

-2 * \frac{3-x}{3} + 5x = 15

Simplify the equation :

\frac{-6+17x}{3} =15

Isolate x in \frac{-6 + 17x}{3} = 15 :

Proving x = 3

Isolate y in y = \frac{3-3}{3} :

Proving y = 0

Your solved system of equations are x being 3, and y being 0.
