Answer:
-1.5
negative and negative
Step-by-step explanation
the number line shows 3 * -1.5 = -4.5
the number line shows three groups of a negative number, which results in a negative.
Answer:
<h2>height = 12 cm</h2>
Step-by-step explanation:
Area of a triangle is given by
![A = \frac{1}{2} bh](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20bh)
where
b is the base
h is the height
From the question
Area = 21 m²
The statement
The height of a triangle is 8 m more than the length of the base is written as
h = 8 + b
Make b the subject
That's
b = h - 8
Substitute the expression into the above formula and solve for the height
That's
![21 = \frac{1}{2} (h - 8)h](https://tex.z-dn.net/?f=21%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%28h%20-%208%29h)
Multiply through by 2
h² - 8h = 48
h² - 8h - 48 = 0
(h + 4)(h - 12) = 0
h + 4 = 0 h - 12 = 0
h = - 4 h = 12
Since the height cannot be a negative number we have the final answer as
<h3>height = 12 cm</h3>

Y = mx + b
where mx is the slope and b is the y-intercept
f(x) ⇒⇒ (0,5) & (4,3)
y = mx + b
5 = m(0) + b ⇒ b or y-intercept is = 5
3 = m(4) + b
3 = m(4) + 5
3 - 5 = m(4)
-2 = m(4)
-2/4 = m
-1/2 = m
y = mx + b ; b is the y-intercept.
h(x) = 3x + 4
h(x) has 4 as the y-intercept
y = mx + b
g(x) = mx + b
3 = m(0) + b
b = 3
f(x) has 5 as the y-intercept
g(x) has 3 as the y-intercept
h(x) has 4 as the y-intercept
g(x) has the lowest y-intercept
