which ordered pair is a solution to the system of inequalities? {y&gt;−2x+y≤4 (−2, −3) (0, −4) (1, 3) (1, 5)
Nadya [2.5K]

Answer:

(0, -4)

Step-by-step explanation:

Given the inequality expression

y>−2x+y≤4

This can be splitted into

y>−2x+y .... 1

and -2x+y≤4 .... 2

From1;

y>−2x+y

y - y >−2x

0 >−2x

-2x < 0

x > 0/-2

x>0

Substitute x = 0 into 2

-2(0)+ y ≤4

y≤4

Hence the solution is (0, -4)

Given that lim x→1 (5x − 3) = 2, illustrate definition 2 by finding values of δ that correspond to ε = 0.1, ε = 0.05, and ε = 0.
kow [346]
\displaystyle\lim_{x\to1}(5x-3)=2

is to say that for any \varepsilon>0, we can find \delta>0 such that 0 implies |(5x-3)-2|.

To that end, we have

|(5x-3)-2|=|5x-5|=5|x-1|

which means that if \varepsilon=0.1 is given, then we can choose \delta=\dfrac{0.1}5=0.02; if \varepsilon=0.05, then \delta=\dfrac{0.05}5=0.01; if \varepsilon=0.01, then \delta=\dfrac{0.01}5=0.002.

Answer:

C. 8x+80.

Step-by-step explanation:

To make this a simple expression, we need to distribute the 8 into x+10. We do this by multiplication. 8*x=8x. 8*10=80. Our new equation is 8x+80.
