3^2x+3-4(3^x+1)+1=0​

Mathematics
1 answer:
Anni [7]3 years ago
4 0

Answer:

3x =  9 /4 x

Step-by-step explanation:

Let's solve your equation step-by-step.

(32)(x)+3−4(3x+1)+1=0

−4(3x)+9x=0

Step 1: Add -9x to both sides.

−4(3x)+9x+−9x=0+−9x

−4(3x)=−9x

Step 2: Divide both sides by -4.

−4(3x)/ −4  =  −9x /−4  

3x =  9 /4 x

Hope this helps!! :)

Mark has $100,000 to invest. His financial consultant advises him to diversify his investment in three types of bonds: short-ter
galina1969 [7]

Answer:

Short-Term investment: 5000$

Intermediate-Term investment: 65000$

Long-Term investment: 30000$

Step-by-step explanation:

To construct our first equation lets define sort-term bond investment as x, long-term investment as y.

So the equation is:

x*0,04+(100000-x-y)*0,05+y*0,06=5250

From the equation it is found that:

y=25000+x

Instead of y, if we put 25000+x the equation will be as following:

x*0,04+75000*0,05+(25000+x)*0,06=5250

From the equation it is found that:

x=5000

Short-Term investment is 5000$

x+25000=y

Long-Term investment is 30000$

Rest of the money is Intermediate-Term investment 65000$

If z = 2, find the value of: a. 6z2–2z+5<br> b. 64–5z
Ludmilka [50]

Answer:

25 and 54

Step-by-step explanation:

(a)

6z² - 2z + 5 ← substitute z = 2

= 6(2)² - 2(2) + 5

= 6(4) - 4 + 5

= 24 - 4 + 5

= 20 + 5

= 25

(b)

64 - 5z ← substitute z = 2

= 64 - 5(2)

= 64 - 10

= 54
