pashok25 [27]

Answer:

1) 4

2) y <= 9

3) NO SOLUTION

4) 24

5) 5 cards

Step-by-step explanation:

1st pic) 2x + 7 = 15

2x + 7 = 15

<u>       -7    -7</u>

2x = 8

divide by 2 to isolate x

<u>x = 4</u>

2nd pic) y - 3 <= 6

y - 3 <= 6

<u>   +3      +3</u>

<u>y <= 9</u>

<u />

3rd pic) x + 0.5 = x + 6

x + 0.5 = x + 6

<u>    -0.5         -0.5</u>

x = x + 5.5

NO SOLUTION

4th pic)  5m + 10 <= 130

5m + 10 <= 130

<u>       -10        -10</u>

5m <= 120

divide by 5 to isolate the m

<u>m <= 24</u>

5th pic) 2c - 8 > 0

2c - 8 > 0

<u>      +8   +8</u>

2c > 8

divide by 2 to isolate the c

<u>c > 4</u>

Write an equation for the line that is parallel to the glven line and that passes
Wewaii [24]

Answer:

The answer to your question is  y = x - 23

Step-by-step explanation:

Process

1.- Get the slope of the line

If two lines are parallels, it means that they have the same slope.

                                 y = 1x - 10

Slope = m = 1

2.- Get the equation of the line

                               y - y1 = m(x - x1)

                               y + 29 = 1(x + 6)                 Substitution

                               y + 29 = x + 6                     Expanding

                               y = x + 6 - 29                      Simplifying

                               y = x - 23

Ms walkers science class is doing an egg drop experiment from the balcony of their school. Each egg is protected by a contraptio
mr_godi [17]

Answer:

The zeros, -1.48 and 1.48, represent the times where the egg is on the ground.

Step-by-step explanation:

The roots, or zeros, of an expression are the x-intercepts.  They are the points where the data crosses the x-axis.  The y-coordinate at these points is 0.  This means the height of the egg at these points is 0.

The values of a, b and c in this equation are -16, 0 and 35.  Using the quadratic formula,

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\=\frac{-0\pm \sqrt{0^2-4(-16)(35)}}{2(-16)}\\\\=\frac{0\pm \sqrt{0--2240}}{-32}\\\\=\frac{0\pm \sqrt{2240}}{-32}\\\\=\frac{0\pm 47.33}{-32}\\\\=\frac{0+47.33}{-32}\text{ or }\frac{0-47.33}{-32}\\\\=\frac{47.33}{-32}\text{ or }\frac{-47.33}{32}\\\\=-1.48\text{ or }1.48
