Answer:

a=25

Step-by-step explanation:

a/5+3=8

Subtract 3 from both sides:

a/5+3 -3=8 -3

a/5=5

Multiply both sides by 5:

5×a/5=5×5

a=25

Hope it helps!

Which set of ordered pairs could be generated by an exponential function?A.(0,0),(1,1),(2,8),(3,27)B.(0,1),(1,2),(2,5),(3,10)C.(

Travka [436]

Answer:

Option D

Step-by-step explanation:

Let an exponential function

$f(x)=ab^x$

Where a=Constant $\neq 0$

$b\neq 0$

We know that

$b^0=1$

Therefore,

Point (0,0) can not be obtained by exponential function.

Hence,option A and C are incorrect.

Substitute (0,1)

$1=a$

$f(x)=b^x$

Substitute (1,2)

$2=b^1$

$\implies b^2=4\neq 5$

Hence, option B is incorrect.

D.(0,1),(1,3),(2,9),(3,27)

$f(1)=b=3$

$b^2=(3)^2=9$

$b^3=3^3=27$

Hence, option D is correct.

Which value of x makes the equation 0.5(x + 15) = 2 + 0.75(x - 4) true?

SIZIF [17.4K]

Answer:

Step-by-step explanation:

$\frac{1}{2}(x+15) = 2 + \frac{3}{4}(x-4)$

To make this easier, to get ride of the fractions, we can multiply both sides by 4

$2(x+15) = 8 + 3(x-4)$

now use the distributive property

$2x + 30 = 8 + 3x - 12\\$

now we want to isolate x to one side and isolate all the constants to the other

$2x - 3x = 8 - 12 - 30\\$

now simplify

$-x = -34\\x = 34$

to test, we can plug in back to the original

$\frac{1}{2}(34+15) = \frac{49}{2}\\\frac{8}{4} + \frac{3}{4}(34-4) = \frac{8}{4} + \frac{90}{4} = \frac{98}{4} = \frac{49}{2}$

it works
