y= 2^2 − 5x is linear. 2^2 is just a constant. The x in 5x has the power 1.

y = x/3 is linear. Think of it as y = (1/3)x. Again, we have the 1st power of x.

y = x^3 + 1/3 is nonlinear. It's a cubic. Note the 3rd power of x.

Y=5x-4 is linear

y=x/3 is linear

y=x^3+1/3 is non linear

Basically linear means it is a straight line when graphed. So anything with exponts is non linear by default among some other rules for determining linear or nonlinear Hope this helps! Please rate my answer and help me also! Thank YOU!!!!!:)

A point is dilated with respect to the origin. Determine the value of K and state whether the dilation is an expansion or contra

vlabodo [156]

Scale Factor (K) = (new length/measure)/ (original length/measure)
for x-coordinate = 8/2 = 4
for y-coordinate = 16/4 = 4

K=4, expansion

K is the representation of "scale factor". Scale factor is the ratio of the lengths involved of the similar figures. It can be used to identify the kind of dilation, whether it is contraction or expansion. If the Scale Factor is greater than 1, then that means expansion and if it is less than 1, then it signifies contraction.

Katy invests a total of $13,000 in two accounts paying 2% and 7% annual interest, respectively. How much was invested in each ac

kherson [118]

Answer:

2 % amount = 12000 7% amount = 1000 dollars

Step-by-step explanation:

x = 2% amount

then 13 000 - x = 7% amount

.02x + .07 (13000-x) = 310

-.05x + 910 = 310

.05x = 600

x = 600/.05 = 12000 then the 7% amount is 1000

Solve the equation using the order of operations. 5+{2×[(5−1)+6]}÷4

creativ13 [48]

Answer:

The order of operations is PEMDAS

First step is to do everything is parenthesis or brackets

5+{2*[(5-1)+6]}/4

{2*[(5-1)+6]}

First you would go 5-1=4, because that is the first equation that is in parenthesis by itself.

{2*[4+6]}

Next you would go 4+6=10, because that is your next smallest bracket

{2*10}

Last you would go 2*10=20

Your equation now looks like this

5+{20}/4

In PEMDAS your next step is exponents, but we don't have any so we go on to the next one which is multiply/division

5+5

You would go 20/4=5

Last step is to add/subtract

5+5=10

Your final answer would be 10

Hope this helps ;)

Find the intersection point between the lines of equations: 2x-y+6=0 and 2x+3y-6=0

Ugo [173]

Step-by-step explanation:

The two equation will intersect each other at the point which will be the solution of the given two equations , and the given equations are ,

$\implies 2x -y +6=0\\\\\implies 2x + 3y -6=0$

On subtracting the given equations we have,

$\implies -y - 3y +6 -(-6) = 0 \\\\\implies -4y = -12 \\\\\implies y = -12/-4\\\\\implies y = 3$

Put this value in any equation , we have ,

$\implies 2x -3 +6 =0\\\\\implies 2x = -3 \\\\\implies x =\dfrac{-3}{2} \\\\\implies x =-1.5$

Hence the lines will Intersect at ,

$\implies\underline{\underline{ Point=(-1.5, 3)}}$

8x+5y=35 solve for y no work needed but you can show me the work if you want i will still look at it thank you in advance

solong [7]

Answer:

y=7-(8/5)x

Step-by-step explanation:

To solve for y we need to get Y on one side of the equation all by itself. To start we can move the 8x to the side with the 35 by subtracting 8x on both sides which gets us to 5y=35-8x then we just need to get the 5 detached from the y and we will have solved for Y. To do this we can divide by 5 on both sides to cancel out the 5 with the Y which leaves us with y=7-(8/5)x

I hope this helps and please don't hesitate to ask if there is anything still unclear!
