Answer:29

Step-by-step explanation:

So 5+1 is 6 and 6x2 is 12. The minus gets distributed into the (12+32) which makes the both negative. So -12-32=-44. And -44+3 is -41. And 12-(-41 )is 29.

HELP PLEASE!! IM REALLY STUPID!! // You have nickels and dimes in your wallet with a total value of $1.10. You have 17 coins in

Dmitry [639]

Answer:

$x=12$ (12 nickels))

$y=5$ (5 dimes)

Step-by-step explanation:

Based on the information given in the problem, you can set up the following system of linear equations, where:

x: number of nickels.

y: number of dimes.

Then

FIRST EQUATION: $x+y=17$

SECOND EQUATION: $5x+10y=110$ (in cents)

You can apply the Substitution method:

- Solve for x from the first equation.

- Substitute into the second equation and solve for y.

Then:

$x=17-y$

$5(17-y)+10y=110\\85-5y+10y=110\\5y=25\\y=5$

- Find x:

$x=17-5\\x=12$

HELP<br> Use the definition of continuity and the properties of limits to show that’s the function…

Solnce55 [7]

Answer with Step-by-step explanation:

We are given that

$g(x)=(x^2-3x-10)(x^2+2x^2-5x+4)$

x=-1

Using property of limit

$\lim_{x\rightarrow -1}g(x)=\lim_{x\rightarrow -1}(x^2-3x-10)(3x^2-5x+4)$

= $(1+3-10)(3+5+4)$

= $(-6)(12)$

= $-72$

$g(-1)=(1+3-10)(1+2+5+4)$

$g(-1)=(-6)(12)=-72$

$\lim_{x\rightarrow -1}g(x)=g(-1)$

Hence, the function is continuous at x=-1
