Mathematics

Katen [24]3 years ago

Answer:

<em></em>y = 12 + 6x<em></em>

<em></em>

Step-by-step explanation:

Given

Base\ Amount = 12

Additional = 6 per hour

Required

Determine the expression for the cost in x hours

Represent the cost with y

y is calculated using the following expression

y = Base\ Amount + Additional * x

Where x represent the number of hours.

Substitute values for the base amount of bike and the additional cost per hour

y = 12 + 6 * x

y = 12 + 6x

<em>So, the expression to determine the cost of bike in x hours is: </em>y = 12 + 6x<em></em>

Solve this system of equations using the substitution method<br>y=x+7<br>-2x-11=y​
ryzh [129]

Answer:

x=-6, y=1

Step-by-step explanation:

Let's solve your system by substitution.

y=x+7;−2x−11=y

Step: Solve y=x+7 for y:

y=x+7

Step: Substitute x+7 for y in −2x−11=y:

−2x−11=y

−2x−11=x+7

−2x−11+−x=x+7+−x(Add -x to both sides)

−3x−11=7

−3x−11+11=7+11(Add 11 to both sides)

−3x=18

−3x/ −3 = 18/ −3  (Divide both sides by -3)

x=−6

Step: Substitute−6 for x in y=x+7:

y=x+7

y=−6+7

y=1  (Simplify both sides of the equation)

Answer:

x=−6 and y=1

Find the area of the shaded region. Round to the nearest tenth.
AURORKA [14]

Answer:

3.5 square cm

Step-by-step explanation:

Area \: of \: both \: squares  \\ =  {2}^{2}  +  {3}^{2}  \\  = 4 + 9 \\  = 13 \:  {cm}^{2}  \\  \\ Area \: of \: both \: right \:  \triangle s \\  =  \frac{1}{2}  \times (2 + 3) \times 2 + \frac{1}{2}  \times3 \times 3 \\  = 5 \times 1+ 1.5 \times 3 \\  = 5 + 4.5 \\  = 9.5 \:  {cm}^{2}  \\  \\ Area \: of \:shaded \: region \\  = Area \: of \: both \: squares\\ - Area \: of \: both \: right \:  \triangle s \\  = 13 - 9.5 \\   \purple { \boxed{ \bold{Area \: of \:shaded \: region = 3.5 \:  {cm}^{2} }}}

Is x + 10 a factor of the function f(x) = x3 − 75x + 250? Explain.
lord [1]
Okay, I worked it out and yes, it is a factor. Once you got x=-10, then you plug it into your formula. from there you can work it out like I did and get the answer. You can also input it into a scientific calcuator and figure it out that way. If you need any more help, go ahead and message me. Hope this helps. You can also but it into the box and divide it that way to find out. whichever way is better for you
