Answer:

5x + 12 = 5x - 7

Step-by-step explanation:

There will be no solution when the coefficients of x are the same on both sides of the equal sign and the constants are different. That is the case for ...

5x + 12 = 5x - 7

This reduces to ...

19 = 0 . . . . . no value of x will make this be true: NO SOLUTION

Lori buys a $400 certificate deposit that earns 1.8% interest compounded monthly how much will a cd be worth in six years

Firlakuza [10]

Answer:

$1445.11

Step-by-step explanation:

The formula to use would be:

$F=P(1+r)^t$

Where

F is the future amount (what we want to find)

P is the present (principal) amount (this is 400)

r is the rate of interest, monthly (1.8% or 0.018)

t is the time in months (6 years = 6 * 12 = 72)

Now substituting, we get:

$F=P(1+r)^t\\F=400(1+0.018)^{72}\\F = 400(1.018)^{72}\\F=1445.11$

After 6 years, the CD will be worth $1445.11

Jenny is displaying her photographs

Inga [223]

Answer:

A) 9 photos in each row

B) 14 rows in total

Step-by-step explanation:

Photos of People = 45

Photos of Landscapes = 18

Photos of Pets = 63

Jenny wants to arrange these photos in rows with only one kind of photos in each row and same number of photos in each row. We have to find the greatest possible number of photos in each row. For this we need to find the greatest common factor of 45,18 and 63. This would give us the greatest possible number of photos that can be placed in each row.

By observing the 3 numbers, we can tell that the greatest common factor of these 3 numbers is 9. So, Jenny can place 9 photos in each row.

So,

There will be:

45/9 = 5 rows with photos of people

18/9 = 2 rows of photos of landscapes

63/9 = 7 rows of photos of pets

So, total number of rows would be = 5 + 2 + 7 = 14 rows

Write the standard form of the equation of the circle described below.

Luden [163]

Equation of circle is $x^2+(y+2)^2=26$

Step-by-step explanation:

The standard form of the equation of circle is:

$(x-h)^2+(y-k)^2=r^2$

where (h,k) is the center of the circle and r is the radius of circle.

We need to find the radius of circle r by using distance formula:

$r=d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}\\r=d=\sqrt{(-5-0)^2+(-1-(-2))^2}\\r=d=\sqrt{(-5)^2+(1)^2}\\r=d=\sqrt{25+1}\\r=d=\sqrt{26}$

r=√26

and r^2= 26

Putting values of r^2=26 and value of center (h,k)=(0,-2)

the equation of Circle is:

$(x-h)^2+(y-k)^2=r^2\\(x-0)^2+(y-(-2)^2=26\\x^2+(y+2)^2=26$
