Answer:

Step-by-step explanation: 4^2 - 8 / (1+3) x 5 = 4^2 - 8 / 4 x 5 = 16 - 8 / 4 x 5 = 16 - 2 x 5 = 16 - 10 = 6

Answer:

D. y = 58

Step-by-step explanation:

Answer:

The value of the polynomial is 58 for x = 6.

Step-by-step explanation:

Here, the given quadratic function polynomial is given as:

or,

Now, to find the value of y, when x = 6

⇒

= 2(36 - 6 -1) = 2(29)

= 58

⇒y(6) = 58

Hence, the value of the given polynomial is 58 for x = 6.

What is the value of x if e^3x+6 = 8?

topjm [15]

We can write any number n in the form $e^{\ln(n)}$ , since $e^x$ and $\ln(x)$ are inverse functions, so that

$e^{3x+6} = 8 \iff e^{3x+6} = e^{\ln(8)}$

The bases are the same on both sides, so the exponents must be equal.

$3x + 6 = \ln(8)$

Solve for x :

$3x = \ln(8) - 6$

$x = \boxed{\dfrac{\ln(8) - 6}3}$

What does ‘x’ equal

Dmitriy789 [7]

Answer:

x=(-9)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(−2/3)(9+x)=0

(−2/3)(9)+(−2/3)(x)=0(Distribute)

−6+−2/3x=0

−2/3x−6=0

Step 2: Add 6 to both sides.

−2/3x−6+6=0+6

−2/3x=6

Step 3: Multiply both sides by 3/(-2).

(3−2)*(−2/3x)=(3−2)*(6)

x=−9

The following system of equations is graphed below.

navik [9.2K]

One way is subsitute
I like solving

so

what you do is this
add the equaitons to gether to eliminate x

2y=x+5
<u>3y=-x-3 +</u>
5y=0x+2
5y=2
y=2/5

sub back

2y=x+5
2(2/5)=x+5
4/5=x+5
minus 5
4/5-25/5=x
-21/5=x

the point is (x,y) or
(-21/5,2/5)
aprox
(-4.2,0.4)
I think they wanted you to read the garph you should have attached and guess the answer
the closes one is
hmm, x=-3
and y=1

so then D is the answer
