Answer:

Question 3: b \geq 2

Question 4: r < -5

Question 5: y \leq -6

Step-by-step explanation:

Question 3:

b + 2 \geq 4\\b + 2  -2 \geq 4 - 2\\b \geq 2\\

Question 4:

13 > 18 + r\\13 - 18 > 18 -18 + r\\\\-5 > r\\ r < -5sign flips when r switches sides

Question 5:

3y \leq 2y - 6\\3y - 2y \leq 2y - 2y - 6\\\\y \leq - 6\\

Write the equation of the given line in slope intercept form (2,3) (8,6)
Dominik [7]

Answer:

y = 1/2x + 2

Step-by-step explanation:

slope:

6 - 3 / 8 - 2 = 3 / 6 = 1/2

start by putting it in point slope form and then simplify it to slope intercept form:

y - 3 = 1/2(x - 2)

y - 3 = 1/2x - 1

y = 1/2x + 2

a right triangle has a base that measures 39 inches and a height that measures 80 inches what is the length of the hypotense
mafiozo [28]
A right triangle has three sides: the two sides that share a vertex are known as the legs, and the other side is known as the hypotenuse.  The legs are known as a and b, while the hypotenuse is c.
The Pythagorean Theorem states the a^2 + b^2 = c^2.  If we plug the numbers into this equation, we will find the length of the hypotenuse.
39^2 + 80^2 = c^2
1521 + 6400 = c^2
7921 = c^2
We have c squared now, but we want to know how much c is equal to.  The square root of c^2 will be our answer.
89 = c
The length of the hypotenuse of a right triangle with legs that measure 39 and 80 inches is 89 inches.

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
