Step-by-step explanation:

Hello there, it seems a little dark in the room. You might want to try turning on the light. I added the image attached to this to solve your questions. Hope this helps.

For 1.) , the linear system is only one solution.

On 2.) , they overlap, therefore, it has infinite solutions.

How can I use the percent equation???Ex.what number is 40% of 500???and can u solve this one,too.:45 is 25% of what number???THA
HACTEHA [7]
I've been waiting for someone to ask this question.  It's one of my favorite questions to answer.

percent means out of 100 so 1% = 1/100 and 40%=40/100 or 1/25
so for percent of a number, 'of' means multiply so 40% of 500= 40/100 times 500 or 20000/100 or 200



if you multiply a fraction by its recipricol (the number fliped upside down) the you will get 1 so if you multiply 1/2 by 2/1 then you will get 1

thus
percent is out of 100 so 1%=1/100  25%=25/100
if you represent 45 out of something as 45/x then you multiply it by the reciprocal of the fraction that is supposed to be equal (1/2 =2/4) then you will get 1
so 45/x times reciprocal of 100/25 then you will get 1/1 or 4500/25x
so you divide to find x and get 180
so 45 is 25% of 180


The following is extra
   as stated above 'of' can be taken as multiply so
   45 is 25% of 180 can be rewriten as
   45=25/100 times 180
   but we don't know that 180 is the answer so we replace it with x then            solve for x

Identify each x-value at which the slope of the tangent line to the function f(x) = 0.2x2 + 5x − 12 belongs to the interval (-1,
Misha Larkins [42]

Answer:

<em>slope of the tangent</em>

<em></em>\frac{d y}{d x} = 0.2(2 x) + 5 (1)<em></em>

<em>The slope of the tangent to the interval (-1 ,1)</em>

<em>m = 4.6 ,5, 5.4</em>

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given function is  f(x) = 0.2 x² + 5 x − 12

Slope of the tangent formula

                        m = \frac{d y}{d x}

Let y =  f(x) = 0.2 x² + 5 x − 12 ...(i)

Differentiating equation(i) with respective to 'x' , we get

\frac{d y}{d x} = 0.2(2 x) + 5 (1) -0

let x=-1

m = \frac{dy}{dx} = 0.2 (2 X -1) +5 = 4.6

let x=0

m = 5

let x=1

m = \frac{dy}{dx} = 0.2 (2 X 1) +5 = 5.4

<u><em>conclusion</em></u>:-

<em>slope of the tangent</em>

<em></em>\frac{d y}{d x} = 0.2(2 x) + 5 (1)<em></em>

<em>The slope of the tangent to the interval (-1 ,1)</em>

<em>m = 4.6 , 5,  5.4</em>

Renee is hiking a trail that is 9¾ miles long. Renee hiked for 4¼ miles. After resting, Renee then hiked for 3½ miles. How many
Inessa [10]

Renee needs to hike 2 miles  to finish the hiking trail

The first step is to add the both miles

She hiked for 4 1/4 miles= 17/4

After resting she then hiked for another 3 1/2 miles= 7/2

17/4 + 7/2

= 31/4

The hiking trail is 9 3/4

To find the number of miles let to finish the trail, let's subtract 31/4 from 9 3/4

39/4 -31/4

= 8/4

= 2

Hence Renee needs to hike for 2 miles to finish the hiking trail
