What is an equation of the line formed when the line y = 2x + 4 is reflected over the line y = x?

Answer:

the answer is D and just keep practicing

Answer:

(-3,-1)

Step-by-step explanation:

To reflect them you gotta switch their places and change their signs from positive to negative.

so (x,y) -> (-y,-x)

Answer:

-1

Step-by-step explanation: hope this helps

Answer:

A reflection of a geometric shape is the mirror image of the shape.

The solution set of the given inequality is  {b| b > 20}.

Here we have the inequality (3/4)b > 15 and we want to solve it. To do so, we just need to isolate the variable b.

And to do it, we can work with this like we would do with any equation, we can just multipy both sides by (4/3) so we get:

(4/3)*(3/4)*b > 15*(4/3)

b > 20

Then the solution set can be written as {b| b > 20}

That is the set of all values larger than 20.

Answer:

Fairview is lower.

Step-by-step explanation:

IXL

The required, city Fairview has a lower ratio of negative to positive reviews.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

here,
A restaurant critic reviewed restaurants in Oxford and Fairview.
In Oxford, the critic gave 18 negative reviews and 33 positive reviews.
ratio = 18 / 33 = 0.54

In Fairview, 5 of the reviews were negative and 11 were positive reviews.
Ratio = 5 / 11 = 0.45

Thus, the required, the city of Fairview has a lower ratio of negative to positive reviews.

Answer:

agree

Step-by-step explanation: you should always divide the bigger number over the smaller number. but if you don't you'd still get the same answer

The percentage pay increase of Lisa's weekly will be 4%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Lisa's weekly pay increased from $525 to $546. Then the percentage pay increase will be given as,

P = [(546 - 525) / 525] x 100

Simplify the expression, then we have

P = [(546 - 525) / 525] x 100

P = (21 / 525) x 100

P = 0.04 x 100

P = 4%

The percentage pay increase of Lisa's weekly will be 4%.

Answer:

85

Step-by-step explanation:

All you do is add 35 units and 50 units together.

Area of the square adjacent to the third side of the triangle is 85 units square

Pythagoras theorem states that a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

Given that areas of the squares adjacent to two sides of a right triangle are :

35 sq units

50 sq units

To determine the area of the square adjacent to the third side of the triangle

According to Pythagoras theorem,

Hypotenuse² = Base² + Perpendicular²

As figure is missing  assuming given sides are perpendicular sides

Then Area of the square adjacent to the third side of the triangle = 35 + 50

= 85 units square

Now, assuming 50 sq unit is an area on hypotenuse

Then Area of the square adjacent to the third side of the triangle  = 35 - 50

= 15 units square

The slope for this problem is -4/3.

Step-by-step explanation:

To find the slope, we can look at it as Rise/Run. The rise is how many units up (+) a point is or how many units down (-) a point is from the starting point. The rise is how many units to the left or right a point is from the starting point.

Now that we understand Rise/Run, we can find the slope. If we go from the highest point, or the point farthest to the left in the picture shown, we can see that we need to go four units down to get to the same level as the next point, so we would be moving -4 units away from the point. We can also see the second point is 3 units to left.

With this information, we can now figure out that the slope is -4/3.

Don't hesitate to ask any questions.

2) WY is the hypotenuse

Step-by-step explanation:

Answer: 72

Plan A = 30 +0.15x

Plan B = 16 +0.20x

30+0.15x = 16+0.20x

subtract 16 from each side

14 +0.15x = 0.20x

subtract 0.15x from each side

14=0.05x

x = 14/0.05 = 280 minutes

280*0.15 = 42 +30 = $72

280 * 0.20 = 56 +16 = 72
