The coordinates of B would be 3,5 because all you have to do is take -3,5 which is in the second quadrant and flip it over the first quadrant (which is the y-axis)

Hope this helps!

Find the exact solution of x <br> 3x^2+7=28<br> A.+√7<br> B.7<br> C.+7<br> D.-7
yulyashka [42]

Answer:

x = ± \sqrt{7}

Step-by-step explanation:

3x² + 7 = 28 ( subtract 7 from both sides )

3x² = 21 ( divide both sides by 3 )

x² = 7 ( take square root of both sides )

x = ± \sqrt{7}

that is x = - \sqrt{7} , x = \sqrt{7}

Zigmanuir [339]

Answer:

( 2x - 3 ) / 5

Step-by-step explanation:

2x - 6 = 5y - 3

2x - 6 + 3 = 5y

2x - 3 = 5y

y = ( 2x - 3 ) / 5

The recipe makes enough stew for 6 people, and the ingredients cost $9.75. How much would it cost to serve 24 people?
Leno4ka [110]

If the recipe makes enough stew for 6 people, and the ingredients cost $9.75, then for 24 people it will cost $x. You can write this statement as

6 people - $9.75,

24 people - $x.

Or as proportion,

\dfrac{6}{24}=\dfrac{9.75}{x}.

Find x:

6\cdot x=9.75\cdot 24,\\ \\x=\dfrac{9.75\cdot 24}{6}=9.75\cdot 4=39.

Answer: It would cost $39 to serve 24 people

A certain pickup truck gets 20mpg in the city and 28 mpg on the highway. If the driver drives 270 mi on 11 gal of gas, determine
Snezhnost [94]

Answer:

95 city and 175 highway miles.

Step-by-step explanation:

The driver gets 20 mpg in city, and 28 mpg on the highway.

An equation that could be written is

20x+28y=270

This equation accounts for the distance traveled.

x+y=11

This equotion accounts for how many gallons were driven.

Multiply the bottom equation by 20, so you can solve the set of equations.

20x+28y=270

20x+20y=220

subtract them

8y=50

y=6.25

now plug this back into x+y=11

x+6.25=11

x=4.75

Now 4.75×20=95 city miles and 6.25×28=175 highway miles.
