How to solve<br> 3/5e-6=-2/5(e-10)-7
kaheart [24]
\frac{3}{5} e-6=- \frac{2}{5}(e-10)-7
\frac{3}{5} e-6=- \frac{2}{5} e- \frac{2}{5}*(-10) -7 \\  \frac{3}{5} e-6=- \frac{2}{5} e+ \frac{20}{5} -7= \frac{3}{5} e-6=- \frac{2}{5} e+4 -7= \\
\frac{3}{5}e-6=- \frac{2}{5} e-3      /*5
3e-18=-2e-15        /+15
3e-3=-2e            /+2e
5e-3=0              /+3
5e=3
e=\frac{3}{5}

You can ride a bicycle 15 mph. Your sister
igor_vitrenko [27]

Answer:

4

Step-by-step explanation:

Find the LCM of 12 and 15.

LCM = 60.

Now divide the LCM by the two numbers.

60/12 = 5, 60/15 = 4.

As the sister got an hour head start, subtract one.

5-1=4.

Therefore it will be 4 hours.

Solve by completing the square
natima [27]

Answer:

see explanation

Step-by-step explanation:

Given

x² + 10x + 14 = - 7 ( subtract 14 from both sides )

x² + 10x = - 21

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(5)x + 25 = - 21 + 25

(x + 5)² = 4 ( take the square root of both sides )

x + 5 = ± 2 ( subtract 5 from both sides )

x = - 5 ± 2

x = - 5 - 2 = - 7, or x = - 5 + 2 = - 3

-------------------------------------------------

The equation can also be solved by factoring

x² + 10x + 14 = - 7 ( add 7 to both sides )

x² + 10x + 21 = 0 ← in standard form

(x + 7)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x + 3 = 0 ⇒ x = - 3

f(x) g(x) ​ =x 2 =x 2 −8 ​ We can think of ggg as a translated (shifted) version of fff. Complete the description of the transfo
Mice21 [21]

Answer:

Step-by-step explanation:

The equation that results from translating the parabola y=x^2y=x

2

y, equals, x, squared to the right by \greenD{h}hstart color #1fab54, h, end color #1fab54 units and up by \goldE{k}kstart color #a75a05, k, end color #a75a05 units is:

y=(x-\greenD{h})^2+\goldE{k}y=(x−h)

2

+ky, equals, left parenthesis, x, minus, start color #1fab54, h, end color #1fab54, right parenthesis, squared, plus, start color #a75a05, k, end color #a75a05

Note that negative values of \greenD{h}hstart color #1fab54, h, end color #1fab54 represent leftward shifts and negative values for \goldE{k}kstart color #a75a05, k, end color #a75a05 represent downward shifts.

Hint #22 / 3

g(x)=(x-\greenD{0})^2+\goldE{(-8)}g(x)=(x−0)

2

+(−8)g, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, start color #1fab54, 0, end color #1fab54, right parenthesis, squared, plus, start color #a75a05, left parenthesis, minus, 8, right parenthesis, end color #a75a05

Since the function is translated up by \goldE{-8}−8start color #a75a05, minus, 8, end color #a75a05, that means it is translated down by 888 units.

Hint #33 / 3

To get the function g, shift f down by 8 units.
