Answer:

(-3, -1/2)

Step-by-step explanation:

Plug in the numbers for x and y. If the left side of the equation is greater than the right side (0), then ordered pair is a solution to the inequality.

Answer:

\large\boxed{\left(-3,\ -\dfrac{1}{2}\right)}

Step-by-step explanation:

Convert the inequality to the form y > mx + b:

-\dfrac{2}{3}x-4y>0          <em>add 2/3x to both sides</em>

-4y>\dfrac{2}{3}x           <em>change the signs</em>

4y       <em>divide both sides by 4</em>

y

y

Put the coordinates of the points to the inequality and check:

for (-15, 3):

3

for (6, 3):

3

for (-3, -1/2):

-\dfrac{1}{2}

for (6, -1/4):

-\dfrac{1}{4}

Answer:

x= -8 , y = 5

x= 25/4 , y = 1/4

Step-by-step explanation:

substitute first eqn into the second eqn:

(7 - 3y)^2 -y^2 = 39

49 - 42y + 9y^2 - y^2 = 39

8y^2 - 42y +10 =0

4y^2 - 21y + 5 = 0

(4y-1) (y-5) = 0

y= 1/4 , 5

when y=1/4

x = 7- 3/4

=25/4

when y= 5

x = 7- 15

= -8

Pls answer clearly thank you will be marking smartest correct answer!
balandron [24]

Number 9 is no because if you were to divide that it be a decimal and a decimal is an irrational number.

Number 10 is yes. When divide 2 by 5 you get 0.4 which is a terminating number because it never ends

The temperatures at several times of the day are shown in the coordinate plane below. The x-axis represents the number of hours
Drupady [299]

Question:

The temperatures at several times of the day are shown in the coordinate plane below. The x-axis represents the number of hours before or afternoon. For example, -1 would represent 11 a.m. The y-axis represents the temperature in degrees Celsius.At 5 p.m, the temperature is halfway between the temperature at 2 p.m. and the temperature at 8 p.m.

What coordinates represent the temperature at 5 p.m.?

Answer:

(5, 2)

=> At 5pm, the temperature is at 2⁰C

Step-by-step Explanation:

Coordinates of any point on a cartesian/coordinate plane is represented by (x, y). Where x is the number at the point on z-axis, while y is the number at the same point on the y-axis.

From the diagram of the coordinate plane attached below, we can simply find out what coordinates represent the temperature at 5pm.

==> Given that the temperature at 5pm is half way between the temperature at 2pm (y=7) and temperature at 8pm (y=-3), the point that is being referred to = [7+(-3)] ÷ 2 = ⁴/2 = 2 (i.e. 2 on the y axis representing temperature)

*The position of the point is indicated in the second picture that is attached below.

At that position of the point, we have 2 as the coordinate for the y axis representing temperature, and at that same position, we have 5 on the x-axis representing the number of hours.

Therefore, coordinates of the point (x, y) representing 5p.m = (5, 2)

==> At 5pm, the temperature is at 2⁰C
