Answer:

x=11, y=13

Step-by-step explanation:

3x-2y=7

3x-2(x+2)=7 .          - x + = -      -2*+2=-4

3x-2x-4=7

1x-4=7

x=7+4

x=11

y=x+2

y=11+2

y=13

Answer:
(11, 13)
Explanation:
The first step when you multiply -2 times 2 would equal -4
Then you would
3x-2x-4=7
x-4=7
x=11
y=x+2
y=11+2
y=13
The error Carolyn made was not multiplying the negative and positive number right.

Find 7% of 280<br> Find 12% of 300<br> Find 2% of $1250
hammer [34]
Percent means parts out of 100
7%=7/100=0.07
'of' means multiply so

7%=0.7
7% of 280=0.07 times 280=196

12%=0.12
12% of 300=36


2%=0.02
2% of $1250=$25

WILL GIVE BRAINLIEST write an equation for the nth term of the arithmetic sequence and find the 30th term 28, 25, 22, 19, ... (s
ryzh [129]

Answer: 31 - 3n

Step-by-step explanation:

step one:

25 - 28 = -3

22 - 25 = -3

19 - 22 = -3

d = -3

Step two:

An = a1 + (n-1) d

= 28 + (n-1) -3

= 28 - 3n + 3

= 31 - 3n

a1= 28 d = 3

Find the values of m and b that make the following function differentiable. the piecewise function f of x equals x cubed when x
aalyn [17]

f(x)=\begin{cases}x^3&\text{for }x\le1\\mx+b&\text{for }x>1\end{cases}

f must be continuous in order to be differentiable, so we need to have

\displaystyle\lim_{x\to1^-}f(x)=\lim_{x\to1^+}f(x)=f(1)

By its definition, f(1)=1^3=1, and

\displaystyle\lim_{x\to1^-}f(x)=\lim_{x\to1}x^3=1

\displaystyle\lim_{x\to1^+}f(x)=\lim_{x\to1}(mx+b)=m+b

so that \boxed{m+b=1}.

We want the derivative to exist at x=1, which requires that we pick an appropriate value for f'(1) so that f'(x) is also continuous. At the moment, we know

f'(x)=\begin{cases}3x^2&\text{for }x1\end{cases}{/tex]so we need to pick [tex]f'(1) such that

\displaystyle\lim_{x\to1^-}f'(x)=\lim_{x\to1^+}f'(x)

We have

\displaystyle\lim_{x\to1^-}f'(x)=\lim_{x\to1}3x^2=3

\displaystyle\lim_{x\to1^+}f'(x)=\lim_{x\to1}m=m

so that \boxed{m=3} (which means we need to pick f'(1)=3) and so m+b=1\implies\boxed{b=-2}
