Plug the ordered pairs into the equation. The first number represents x, the second number y. The answer is D. -10=5(-2)

Answer:

The answer is d. (-2,-10)

Step-by-step explanation:

In order to determine which ordered pair is a solution of the equation, we have to understand that if we replace the variables into values, the equality must remain. The first value of the ordered pair represents the "x" variable and the second value represents the "y" variable.

So, for every option:

a)

x=-2\\y=10\\\\y=5*x\\10=5*(-2)\\10=-10

There is NOT equality

b)

x=-5\\y=25\\\\y=5*x\\25=5*(-5)\\25=-25

There is NOT equality

c)

x=-3\\y=15\\\\y=5*x\\15=5*(-3)\\15=-15

There is NOT equality

d)

x=-2\\y=-10\\\\y=5*x\\-10=5*(-2)\\-10=-10

There is equality

Finally, the only ordered pair that fulfill the equality is (-2,-10)

Evaluate: f(x) = 2x^2 + 6x - 4; f(-5) *
jasenka [17]

f(x)=2x^2+6x-4\\

Find f(-5) by substituting x = -5 in the equation.

f(-5)=2(-5)^2+6(-5)-4\\f(-5)=2(25)-30-4\\f(-5)=50-34\\f(-5)=16

Therefore, the answer is f(-5) = 16

I WILL MARK YOU BRAINLIEST!PLEASE SOLVE FOR X
polet [3.4K]

Answer and Step-by-step explanation:

We see that the bottom two lines are parallel, which makes angle x and angle 5 "same-side corresponding angles". By definition, same-side corresponding angles are congruent. That means angle x = angle 5.

Note that you didn't provide any measures, so it is impossible to actually figure out an exact degree. However, angle x is the same degree as angle 5.

Hope this helps!

The kitchen-tile installer has 20 green, 14 beige, and 16 white tiles in a box. What is the probability of picking a beige tile
Stels [109]

Answer: P = 0.28

Step-by-step explanation:

If we pick it at random, the probability of selecting each tile must be equal. this means that the probability of picking a tile of a giving color is equal to the number of the tiles of that color divided the total number of tiles.

We have 14 beige tiles and 20 + 14 + 16 = 50 tiles in total.

Then the probability of piking a beige tile is:

P = 14/50 = 0.28

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was
Allushta [10]

Answer:

115 = 15 x + 40

the charge is $5 dollars per mile

Step-by-step explanation:

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115

LEt x  be  the charge in dollars per hour

Initial charge is 40 and 15 miles travelled  in one day

total charge = 15x + 40

Given : total charge is 115

So the equation becomes

115 = 15 x + 40

Now we solve for x

Subtract 40 from both sides

75= 15 x

Divide both sides by 15

x= 5

so , the charge is $5 dollars per mile
