Answer:

y ≥ -2x +1
y ≤ 2x +4

Step-by-step explanation:

The downward-sloping line has a y-intercept of 1 and a slope of -2, so its equation is ...

y = -2x +1

The graph is shaded on and above that line, so the inequality it represents is ...

y ≥ -2x +1

The upward-sloping line has a y-intercept of +4 and a slope of +2, so its equation is ...

y = 2x +4

The graph is shaded on and below that line, so the inequality it represents is ...

y ≤ 2x +4

Then the system of inequalities is ...

y ≥ -2x +1

y ≤ 2x +4

Select all the expressions equivalent to: (4^5)⋅4^3 Group of answer choice 2^14 4^12 2^16 16^8 4^8 16^4

kumpel [21]

Answer:

Choices given as $2^{16}, 4^8$ and $16^4$ are correct.

Step-by-step explanation:

Given expression is,

$(4^5)(4^3)$

By applying law of exponents in the given expression,

$(4^5)(4^3)=4^{5+3}$

$=4^8$

$(4^5)(4^3)=(2^2)^5(2^2)^3$

$=(2^{2\times 5})(2^{2\times 3})$

$=2^{10}\times 2^6$

$=2^{16}$

$=(2^4)^4$

$=(16)^4$

Therefore, choices given as $2^{16}, 4^8$ and $16^4$ are correct.

What is the x-value in the solution to this system of linear equations? 2x − y = 11 x + 3y = −5

Setler [38]

Answer:

x = 4

Step-by-step explanation:

Given the 2 equations

2x - y = 11 → (1)

x + 3y = - 5 → (2)

Multiply (1) by 3 and add to (2) to eliminate the y- term

6x - 3y = 33 → (3)

Add (2) and (3) term by term to eliminate y, that is

7x = 28 ( divide both sides by 7 )

x = 4
