Answer:

Upstream 18mph              Downstream  36 mph

Step-by-step explanation:

Upstream DATA:

distance = 180 miles ; time = 10 hrs ; rate = 180/10= 18 mph

-----

Downstream DATA:

distance = 180 miles ; time = 5 hrs ; rate = 180/5= 36 mph

------

Equation:

Upstream: b - c = 18 mph

Downstream: b + c = 36 mph

Now solve for "b"

solve for "c"

Solve the exponential function
nikklg [1K]

Answer:

See below.

Step-by-step explanation:

Just like 18, continue with 19-21. Solve for x by rewriting each equation in log form.

e^x = 4.9\\\\x = ln 4.9\\\\x = 1.59

When rewriting the form, the base of the exponent becomes the base of the log.

B)Emily either switched the signs for no reason or solved it in the incorrect order

C) The sudent solved the equation in an incorrect order. Emily solved the first, then third, then second, which was the incorrect order. Edgar solved the thirst root, then second, then third, thus he is correct.

Pls help me in these two little exercises about the slope.
den301095 [7]

Answer:

3)  y=\dfrac35x+\dfrac25

4) a)  y=-2x+7

  b)  y=\dfrac12x+\dfrac92

Step-by-step explanation:

<u>Exercise 3</u>

-3x + 5y = 2

\implies 5y = 3x + 2

\implies y=\dfrac35x+\dfrac25

<u>Exercise 4</u>

a) If L2 is parallel to L1, it has the same slope (gradient) ⇒ m = -2

If L2 passes through point (3, 1):

y-y_1=m(x-x_1)

\implies y-1=-2(x-3)

\implies y=-2x+7

So L2 = L1

b) If L3 is perpendicular to L1, then the slope of L3 is the negative reciprocals of the slope of L1  ⇒  m = \dfrac12

If L3 passes through point (-5, 2):

y-y_1=m(x-x_1)

\implies y-2=\dfrac12(x+5)

\implies y=\dfrac12x+\dfrac92
