I don't know what your looking for, so be more specific, but I'm assuming your solving for x, so that's would be

x = -1

Answer:

We can simply solve all of these by simplifying them :)

1 . 13 - 4x = 1 - x =

x = 4

2 . 7a - 3 = 3 + 6a =

a = 6

3 . 5 + 2x = -2x + 6 =

x = 1/4

4 . -11 + x = 7x - 5 =

x = -1

Find the area of each figure.

kari74 [83]

Answer:

132 m²

Step-by-step explanation:

The rectangle is 20 m by 6 m.

Base of triangle: 20 m - 8 m - 6 m = 6 m

Height of triangle: 10 m - 6 m = 4 m

The triangle has a base of 6 m and a height of 4 m.

A = LW + bh/2

A = 20 m × 6 m + (6 m × 4 m)/2

A = 120 m² + 12 m²

A = 132 m²

Find the horizontal asymptote off of x equals quantity 3 x squared plus 3x plus 6 end quantity over quantity x squared plus 1.

vaieri [72.5K]

Answer:

y = 3

Step-by-step explanation:

y = (3x² + 3x + 6) / (x² + 1)

The power of the numerator and denominator are equal, so as x approaches infinity, y approaches the ratio of the leading coefficients.

y = 3/1

What are the possible values of x for the following functions?

stiks02 [169]

What can a denominator never be?

0

so, we need to figure what x can't be... the only way to multiply 2 things together to get 0 is if one or both are zero.

so, what x values make our denominator 0?

to figure this out, we need to set (x-1)(x-2)=0

now we split and solve.

$x - 1 = 0 \\ x - 2 = 0$
so when x is 1 or 2 the function doesnt make sense.

but, x can be every other number and it does, so the answer is
ALL REAL NUMBERS not equal to 1 or 2

Tom simplified an expression in three steps, as shown: x to the power of negative 2 multiplied by y to the power of 4, over y mu

ss7ja [257]

Answer:

Step 1, all the exponents are increased by 4

Step-by-step explanation:

The three steps are

(x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ =
x²×y⁸/y⁴×x⁸×x⁸×y² =
x²×y⁸/y⁶×x¹⁶

Correct solution should be:

(x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ = all powers inside the parenthesis should be multiplied by 4 as per power of the power (xᵃ)ᵇ = xᵃᵇ

This would give next steps:

x⁻⁸×y¹⁶/y⁴×x⁸×x⁸×y⁻⁸ =
x⁻⁸×y¹⁶/x¹⁶×y⁻⁴ =
y²⁰/x²⁴

Answer options:

Step 1, all the exponents are increased by 4

There should be multiplication of powers. (It is close option but is not fully correct as not all the exponents increased by 4, for example y became y⁴)

Step 2, the exponents of the same base are added during multiplication

It was done correctly

Step 3 wasn't performed yet, there was step 1 and 2.

So answers about step 3 are irrelevant
