Hello there! :)

Answer:

-41r-16

*The answer must have a negative sign.*

Step-by-step explanation:

Using Properties to Simplify Expressions

Distributive property: a(b+c)=ab+ac

First, expand equation.

$8(-5r-2)=8*5=40=-40r-16$

$-r-40r-16$

Then add by similar to elements.

$-r-40r=-41r$

Answer: $=-41r-16$

Hope this helps!

-Charlie

Answer: 17 nickels, 8 dimes

Step-by-step explanation:

Since we are given system of equations, we can use elimination method to find n or d. First, let's eliminate n. To do so, we need to make sure they are equal to each other. Then, we would have to multilpy the second equaiton by 0.05.

0.05N+0.1D=1.65

0.05N+0.05D=1.25

Now, we can subtract the 2 equations.

0.05D=0.4

D=8

Now that we know the number of dimes, we can plug it into any of the equations to find nickels.

N+8=25

N=17

There are 17 nickels and 8 dimes.

First-order linear differential equations

kkurt [141]

Answer:

$(1)\ logy\ =\ -sint\ +\ c$

$(2)\ log(y+\dfrac{1}{2})\ =\ t^2\ +\ c$

Step-by-step explanation:

1. Given differential equation is

$\dfrac{dy}{dt}+ycost = 0$

$=>\ \dfrac{dy}{dt}\ =\ -ycost$

$=>\ \dfrac{dy}{y}\ =\ -cost dt$

On integrating both sides, we will have

$\int{\dfrac{dy}{y}}\ =\ \int{-cost\ dt}$

$=>\ logy\ =\ -sint\ +\ c$

Hence, the solution of given differential equation can be given by

$logy\ =\ -sint\ +\ c.$

2. Given differential equation,

$\dfrac{dy}{dt}\ -\ 2ty\ =\ t$

$=>\ \dfrac{dy}{dt}\ =\ t\ +\ 2ty$

$=>\ \dfrac{dy}{dt}\ =\ 2t(y+\dfrac{1}{2})$

$=>\ \dfrac{dy}{(y+\dfrac{1}{2})}\ =\ 2t dt$

On integrating both sides, we will have

$\int{\dfrac{dy}{(y+\dfrac{1}{2})}}\ =\ \int{2t dt}$

$=>\ log(y+\dfrac{1}{2})\ =\ 2.\dfrac{t^2}{2}\ + c$

$=>\ log(y+\dfrac{1}{2})\ =\ t^2\ +\ c$

Hence, the solution of given differential equation is

$log(y+\dfrac{1}{2})\ =\ t^2\ +\ c$

Consider the quadratic equation x? = 4x - 5. How many solutions does the equation have? A The equation has one real solution. Th

anzhelika [568]

Answer:

{-1, 5} (two real solutions).

Step-by-step explanation:

On the left side we want x^2, not x?

We need to rewrite x? = 4x - 5 in standard form, that is, as a quadratic with x terms in decreasing powers of x:

x^2 - 4x + 5 = 0

This factors easily to (x - 5)(x + 1) = 0.

We let each factor equal zero (0) separately and solve for x:

{-1, 5} (two real solutions).

Two angles are supplementary angles. One angle measures 58 degrees. The other angle measures 3n + 5 degrees. What is the value o

stepladder [879]

Answer:

Step-by-step explanation:

Angles are supplementary when they add up to 180. So, we know the other angle that isn't 58 is $180-58=122$ . Therefore, $122=3n+5\\3n=117\\n=39$
