Answer:

(5,-3)

Step-by-step explanation:

y+3 = 3x-15

y= -2x + 7

plulg y in

-2x+7+3 = 3x-15

combine like terms

-2x+10 = 3x-15

add 2x to both sides and add 15 to both

5x=25

x=5

y=-2(5) + 7

y= -10 + 7

y= -3

(5,-3)

Match the symbol to the meaning f(x) \rightarrow -\infty Answer 1 x \rightarrow a^- Answer 2 x \rightarrow -\infty Answer 3 x \r

Helen [10]

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Define the key terms

$\begin{gathered} f(x)\Rightarrow o\text{utput} \\ \rightarrow\Rightarrow approaches \\ a\Rightarrow a \\ \infty\Rightarrow\text{ infinity} \\ -\infty\Rightarrow\text{negative infinity} \end{gathered}$

STEP 2: Match the symbol to the meaning

Hence, the correct meaning matching will be:

$\begin{gathered} f(x)\rightarrow-\infty\Rightarrow\text{the output approaches negative infinity} \\ x\rightarrow a^-_{}\Rightarrow x\text{ approaches a from the }left \\ x\rightarrow-\infty\Rightarrow x\text{ approaches negative infinity} \\ x\rightarrow a^+\Rightarrow x\text{ approaches a from the right} \\ x\rightarrow\infty\Rightarrow x\text{ approaches infinity} \\ f(x)\rightarrow a\Rightarrow the\text{ output approaches a} \\ f(x)\rightarrow\infty\Rightarrow the\text{ output approaches infinity} \end{gathered}$

1)Which of these systems of linear equations has an infinite number of solutions?

Alja [10]

1) B)3x+6y=22
6x+12y=44
because the equations are equivalent to each other
2*(3x+6y=22) -----> 6x+12y=44

2) 5x+10y=15 should be multiplied by -2, to get 5x*(-2)=-10x, and x then can be eliminated
A)-2
