Compare the decimals 16.30 and 16.3

1 answer:

8 0

16.30 and 16.3 equal. If you ever have a problem like that then you just add on a zero.

Example:
19.4500 = 19.45 Just add two zeros on the end
19.45 + two zeros = 1.4500

Examine the system of equations. −5x 5y = 40 4x 3y = 24 What is the solution? ( , ).

Elden [556K]

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

The solution of the equation is (0,8)

<h3>What is system of equation?</h3>

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Given information-

The first equitation given in the problem is,

$-5x+5y = 40$

Divide both side of the above equation with 5 as,

$\dfrac{(-5x+5y )}{5}= \dfrac{40}{5}\\-x+y=8\\y=8+x$ .......1

Let the above equation as equitation 1.

The first equitation given in the problem is,

$4x+ 3y = 24$

Put the value of <em>y</em> form the equation 1 in the above equation as,

$\begin{aligned}4x+ 3(x+8) &= 24\\4x+ 3x+24 &= 24\\4x+ 3x &= 24-24\\7x&=0\\x&=0\\\end$

Put the value of <em>x</em> in the equation one as,

$y=8+0\\y=8$

Thus the solution of the equation is (0,8)

Which graph represents the function? f(x)=(x+2)^2 if x<−1

IgorC [24]

Answer:

option B

Step-by-step explanation:

To get the graph of piecewise function

We make a table for each function

Plug in end points and make a table

First function f(x) = (x+2)^2 if x<-1

x <-1 so we pick number for x less than -1. Also we use -1 but we use open circle at x=-1

x y = (x+2)^2

-3 (-3+2)^2= 1

-2 (-2+2)^2 = 0

-1 (-1+2)^2 = 1

Now plot the table on graph

second function f(x) = |x| + 1 if -1<=x<=1

Make a table, we use -1, 0 and 1 because we have -1<=x<=1 (-1 and 1 are included)

x y=|x| +1

-1 |1| + 1 = 2

0 |0|+1 = 1

1 |1|+1= 2

Third function $y=-\sqrt{x}$ if x>1

We find out y when x=1 and make a open circle at x=1 because we have x>1

x $y=-\sqrt{x}$

1 $-\sqrt{1}=-1$

4 $-\sqrt{4}=-2$

Plot all the point on the graph

Correct graph is attached below

Find the measure of angle A when two angles are congruent?

erica [24]

m∡A = 70º

1) Considering that the Sum of the interior angles within a triangle is always 180º

2) We can write the following, and solve for x

x+80 + x +80 +40 = 180

2x +160 +40 = 180

2x + 200 = 180

2x =180-200

2x= -20

x=-10

3) So since angle A = x +80, we can plug it into that the value of x

m∡A = x +80º

m∡A=-10+80

m∡A = 70º

What the center of <br> X^2+(y+3)=9

olga_2 [115]

Assuming you mean $x^2+(y+3)^2=9$ , which is the equation of a circle :

the general equation of a circle of radius $R$ and center $(a,b)$ is $(x-a)^2+(y-b)^2=R^2$ hence here the center is $\boxed{(0,-3)}$
