Answer:
y = x + 3
Step-by-step explanation:
y = mx + b
m is the slope
b is the y intercept
if m = 1 and b = 3 then
y = x + 3
Step-by-step explanation:
The number line is a line with marks, where each mark represents a real number.
In the vertical number line zero is in the center. The numbers above zero are considered positive and the numbers below zero are considered negative.
4
3
2
1
0
-1
-2
-3
-4
The numbers after zero start from 0, 1, 2 ...... and 0, -1, -2.....
Hence, Carlos is wrong and -4 is further to zero than -2
Complete question is;
A 21 ft ladder is leaning against a tall wall with the foot of the ladder placed at 7 feet from the base of the wall and the angle of elevation is?
Answer:
θ = 70.5°
Step-by-step explanation:
The angle of elevation simply means the angle that the ladder makes with the ground. Let's call this angle θ.
I've attached a diagram showing the triangle made by this ladder and the wall.
From the attached diagram, we can see the triangle formed by the ladder and the wall.
We can find the angle of elevation θ from trigonometric ratios.
Thus;
7/21 = cos θ
cos θ = 0.3333
θ = cos^(-1) 0.3333
θ = 70.5°
