Answer:

10/8 or 1 1/5

Step-by-step explanation:

1) distributive property

6(x+2)+7=5(x+3)-7(x-2)
6x+12+7=5x+15-7x+14

2) combine like terms

6x+19=-2x+29
8x=10

3) isolate x

divide both sides by 8

4)simplify

10/8 --> 1 1/5

Answer:

X=5/4

Step-by-step explanation:

6(x+2)+7=5(x+3)-7(x-2)

(6x+6.2)+7=(5x+5.3)-(7x-7.2)

(6x+12)+7=(5x+15)-(7x-14)

6x+12+7=5x+15-7x+14

6x19=5x-7x+15+14

6x19=-2x+29

8x=10

8x/8 = 10/8

X=2.5/2 square root 3

X=5/2 square root 3 - 1

X=5/4

3 Ximena draws an X shape in the coordinate plane as shown. Draw the images of

VARVARA [1.3K]

When a shape is rotated, it must be rotated around a point.

<em>See attachment for the image of each rotation.</em>

To do this, the top coordinates of the X shape will be transformed using the appropriate rotation rule; the same rule will then be applied to the other parts of the X shape.

The top coordinates of the X shape are:

$A = (0,0)$

$B = (1,0)$

$C = (3,0)$

$D =(4,0)$

For 90 degrees counterclockwise rotation, the rule is:

$(x,y) \to (-y,x)$

So, we have:

$A' = (0,0)$

$B' = (0,1)$

$C' = (0,3)$

$D' = (0,4)$

For 180 degrees rotation, the rule is:

$(x,y) \to (-x,-y)$

So, we have:

$A' = (0,0)$

$B' = (-1,0)$

$C' = (-3,0)$

$D' = (-4,0)$

For 270 degrees counter rotation, the rule is:

$(x,y) \to (y,-x)$

So, we have:

$A' = (0,0)$

$B' = (0,-1)$

$C' = (0,-3)$

$D' = (0,-4)$

See attachment for the image of each rotation

Find the balance on a deposit of $455 that earns 4% interest compounded annually for 2 years. $36.40 $491.40 $492.13 $819

STatiana [176]

$A=P(1+ \frac{r}{n})^{tn}$
A=future amount
P=present amount
r=rate in decimal
n=number of times per year compounded
t=time in years

given
P=455
r=4%=0.04
n=1
t=2

$A=455(1+ \frac{0.04}{1})^{(2)(1)}$
$A=455(1+ 0.04)^{2}$
$A=455(1.04)^{2}$
A=492.128
round
$492.13

BRAINLIEST!!! Plz help ASAP

Svetllana [295]

Answer: R = (4, 5)

Step-by-step explanation: Midpoint is simply the center of a line. So, the equation for it is ((x1+x2)/2, (y1+y2)/2). Hence for this,

x coordinate- (6+x)/2=5

x=4

y coordinates- (9+y)/2=7

y=5

And therefore R is (4, 5)
