Convert decimal to fraction
a^2+(21/10)^2=2.9
Use exponent rules
a^2+441/100=2.9
Move constant to the right
a^2=2.9-441/100
Calculate
a^2=-151/100
This equation has no solution.

Plz help been stuck on this for awhile

Answer:

<em>d</em> = $\sqrt{74}$ or 8.60

Step-by-step explanation:

(5, 8) (-2, 3)

Let 5 = $x_{1}$

8 = $y_{1}$

-2 = $x_{2}$

3 = $y_{2}$

Plug in the values into the equation to get the distance:

<em>d = </em> $\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }$ <em />

<em>d </em>= $\sqrt{(-2-5)^{2} + (3-8)^{2} }$

<em>d = </em> $\sqrt{(-7)^{2} + (5)^{2} }$

<em>d</em> = $\sqrt{49 + 25}$

<em>d = </em> $\sqrt{74}$ or 8.60

For each graph, write the equation of the given translation

jasenka [17]

Answer:

Step-by-step explanation:

if you modify the parent function to go <u>up and down</u>

for example parent function is y=|x| to go <u>down</u> 3 you do y=|x|-3

if you modify the parent function to go <u>left and right</u>

for example parent function is y=|x| to go <u>right </u>3 you do y=|x-3|

a.goes down 3, and 2 to the right

y=|x-2|-3

b. 3 down and 1 to the left

y=(x+1)²-3

c. 5 up and 2 to the right

d. 1 up and 5 to the right

How do you graph y=-3x+4

Art [367]

It's a linear function. The graph is a straight line, therefore we need only two points.

Select any value of x and calculate the value of y:

y = -3x + 4

for x = 0 → y = -3(0) + 4 = 4 → (0, 4)

for x = 2 → y = -3(2) + 4 = -2 → (2, -2)

Can someone please help me??

Answer:

I is clear that, the linear equation $5x+12=5x-7$ has no solution.

Step-by-step explanation:

<u>Checking the first option:</u>

$\frac{2}{3}\left(9x+6\right)=6x+4$

$6x+4=6x+4$

$\mathrm{Subtract\:}4\mathrm{\:from\:both\:sides}$

$6x+4-4=6x+4-4$

$6x=6x$

$\mathrm{Subtract\:}6x\mathrm{\:from\:both\:sides}$

$6x-6x=6x-6x$

$0=0$

$\mathrm{Both\:sides\:are\:equal}$

$\mathrm{True\:for\:all}\:x$

<u>Checking the 2nd option:</u>

$5x+12=5x-7$

$\mathrm{Subtract\:}5x\mathrm{\:from\:both\:sides}$

$5x+12-5x=5x-7-5x$

$\mathrm{Simplify}$

$12=-7$

$\mathrm{The\:sides\:are\:not\:equal}$

$\mathrm{No\:Solution}$

<u>Checking the 3rd option:</u>

$4x+7=3x+7$

$\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}$

$4x+7-7=3x+7-7$

$\mathrm{Simplify}$

$4x=3x$

$\mathrm{Subtract\:}3x\mathrm{\:from\:both\:sides}$

$4x-3x=3x-3x$

$\mathrm{Simplify}$

$x=0$

<u>Checking the 4th option:</u>

$-3\left(2x-5\right)=15-6x$

$\mathrm{Subtract\:}15\mathrm{\:from\:both\:sides}$

$-6x+15-15=15-6x-15$

$\mathrm{Simplify}\$

$-6x=-6x$

$\mathrm{Add\:}6x\mathrm{\:to\:both\:sides}$

$-6x+6x=-6x+6x$

$\mathrm{Simplify}$

$\mathrm{Both\:sides\:are\:equal}$

$\mathrm{True\:for\:all}\:x$

Result:

Therefore, from the above calculations it is clear that, the linear equation

$5x+12=5x-7$ has no solution.
