1.   have your number line. number it from left to right 1, 2 , 3 , 4, 5 and so on. Then put a circle over 3 that is filled in because this sign means that x can be equal to 3. A not filled in circle means that x cannot be equal to 3. Then think. Is the sign menaing that x is less than or greater than 3. If it is greater than draw a squiggly line to the right. If it is less than draw a line to the left (starting from 3) Hope this helps with question 1.

If m = 7x + 7, m = 4y, and m = 112, find the values of x and y
tester [92]
<span>If m = 7x + 7, m = 4y, and m = 112

since m = 112

112 = 7x + 7
112 - 7 = 7x
105= 7x
x = 15

112 = 4y
y = 28</span>

Find the equation of the line that has a slope of 3 and passes through (-1, 2)
Nadusha1986 [10]

Answer:

y= 3x+5

Step-by-step explanation:

start with the linear equation formula

y= mx+b

indentify what you already have.

x= -1 and y= 2 and m(slope)= 3

We are solving for b, so plug in what you have.

2= 3(-1)+b

Simplify.

2= -3+b

Add 3 on both sides.

5= b

Rewrite your equation with the x and y values.

y= 3x+5

1. The prism-shaped roof has equilateral triangular bases. Create an equation that models the height of one of the roof's triang
lana66690 [7]

Answer:

h=\frac{\sqrt{3}}{2}b\ units    

Step-by-step explanation:

we know that

An equilateral triangle has three equal sides and three equal interior angles (the measure of each interior angle is equal to 60 degrees)

see the attached figure to better understand tyhe problem

Let

h ----> the height of an equilateral triangle

b ---> the length side of an equilateral triangle

In the right triangle ABD

Applying the Pythagorean Theorem

AB^2=AD^2+BD^2

substitute the given values

b^2=(\frac{b}{2})^2+h^2  

b^2=\frac{b^2}{4}+h^2

h^2=b^2-\frac{b^2}{4}

h^2=\frac{3}{4}b^2

square root both sides

h=\frac{\sqrt{3}}{2}b\ units
