Answer:

B. None

Step-by-step explanation:

We can use substitution for this.

First solve the first equation for y:

y + 7x = -3

y = -7x - 3

Now, substitute this expression in for y in the second equation:

14x + 2(-7x - 3) = 6

We can then solve for x:

14x - 14x - 6 = 6

0 - 6 = 6

-6 = 6

However, we know that -6 ≠ 6, so there are no solutions to this system. Thus, the answer is B, none.

Hope this helps!

Answer:

no solutions

Step-by-step explanation:

y+7x =-3

14x+2y = 6

Multiply the first equation by -2 to eliminate x and y

-2y-14x = 6

14x+2y = 6

--------------------------

0 = 12

This is never true, so there are no solutions

Answer:

f(-5)=2, f(-2)=4

Step-by-step explanation:

-5<-4, so you use the first function in the piece wise function. You plug in -5 for x in 2^x+6, which gives you 2^1=2

-4<-2=2, so you use the second equation in the piecewise function. You plug in -2 for x, which gives you 2(-2+3)^2 +2, or 2(1)^2 +2 = 2 + 2 = 4

Simplify the following equation. <br> (4x^2+3)-(-3x^2-x+5)

AnnyKZ [126]

Answer:

7x² + x – 2

Step-by-step explanation:

(4x² + 3) – (–3x² – x + 5)

First, distribute the minus sign to eliminate the parentheses (negative terms become positive and vice versa):

4x² + 3 + 3x² + x – 5

Then, combine like terms:

7x² + x – 2

Richard simplified an expression in three steps, as shown:

soldi70 [24.7K]

Answer:

Step 2 because Richard multiply the powers of same base in denominator instead adding powers of same base.

Step-by-step explanation:

We are given that Richard simplified an expression in threes steps

We have to find the incorrect step in simplification of Richard

Step 1: all the exponent are multiplied by 3

$\frac{x^{-4}y^2}{yx^2\cdot x^2y^{-4}}^{3}=\frac{x^{-12}y^6}{y^3x^6\cdot x^6y^{-12}}$

Step 2:The exponents in the denominator are multiplied

$\frac{x^{-12}y^6}{y^3x^6\cdot x^6 y^{-12}}=\frac{x^{-12}y^6}{x^{12}y^{-9}}$

Step 3:The exponents of the same base are subtracted during division

$\frac{x^{-12}y^6}{x^{12}y^{-9}}=x^{-12-12}y^{6+9}$

$=x^{-24}y^{15}$

Richard makes mistake in step 2 when we multiply then power of same base should be added but Richard multiply the powers of same base in denominator.

Find the total ° of the shape.
(5-2) x 180°= 540°

x+21°+x = 540°-105°-154°-88°
2x+21° = 193°
2x = 193°-21°
2x = 172°
x = 172° ÷ 2
x = 86°
