What’s the decimal 3.5 as a percent%?

350 %    3.5 × 100 and add the % which means ÷ 100

Step-by-step explanation:

To change a decimal to a percent, multiply by 100, then add %

For example, If a store is having a huge 50% off sale, you figure half of anything is .5 of the regular price.

You get that by dividing the denominator 2 into the numerator on a calculator. 1/2 is  1 ÷ 2 = .5  If a batter hits .500, it means getting a hit at half of their at-bats. Same thing.

Take the .500. Multiply by 100. Easily done by moving the decimal 2 places to the right. Now that's 50.0 Drop the useless 0 after the decimal and it's 50%

50/100 is the same as 1/2

Percents greater than 100 are tricky. If someone says "Attendance was up by 350%" It means there were Three and a half times more people than last time they counted.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
