3 0

Answer:

(- 7, 4 )

Step-by-step explanation:

Given the 2 equations

5x + 3y = - 23 → (1)

y = 4 → (2)

Substitute y = 4 directly into (1_

5x + 3(4) = - 23, that is

5x + 12 = - 23 ( subtract 12 from both sides )

5x = - 35 ( divide both sides by 5 )

x = - 7

Solution is (- 7, 4 )

The probability of picking a head and a number 4 is 0.25.

<h3>How to calculate the probability?</h3>

Your information is incomplete and the complete information wasn't found. An overview will be given.

A coin has a head and tail and the probability of choosing either is 1/2 or 0.5.

Let the 2 numbers be 1 and 4. The probability of picking either number will be 1/2 or 0.5 as well.

Here, let the probability of picking a head and a number 4 will be:

= 1/2 × 1/2

= 0.5 × 0.5

= 0.25

Suppose f(x)= x^2 fins the graph of f(x-1)
Gennadij [26K]
F(x)=x2,

g(x)=f(3x)=(3x)2=9x2

Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric aroung y  axis. When x=1/3 or -1/3, then y=1.

So, try to draw the graph.

marysya [2.9K]
The parent volunteers:
120 snow cones ... 5 hours
x snow cones = ? ... 1 hour

120 * 1 = 5 * x
120 = 5 * x   /5
x = 120 / 5 = 24 snow cones

The student council:
100 snow cones ... 4 hours
y snow cones = ? ... 1 hour

100 * 1 = 4 * y
100 = 4 * y   /4
y = 100 / 4 = 25 snow cones

Result: The student council made more snow cones per hour (25 > 24).
