Answer:
22 square units
Step-by-step explanation:
Area of a triangle formula:
A = 0.5bh
Given:
b = 11
h = 4
Work:
A = 0.5bh
A = 0.5(11)(4)
A = 5.5(4)
A = 22
x-intercept is -16
Step-by-step explanation:
- Step 1: Find the x-intercept of the line y = 1/2 x + 8
x-intercept is the point of intersection of the line with the x-axis. Then y = 0.
⇒ 0 = 1/2 x + 8
⇒ -8 = 1/2 x
∴ x = -16
Answer:
36
Step-by-step explanation:
4(a+b)-c
4(4)+4(8)=16+32-12
48-12=36
Someone answer the question on page btw ion kn the answer to this
The reflection of any point across the x axis is the symmetric of this point, having x axis as axe of symmetry
Let :
A(1,3) its symmetric vs. x axis is A'(1,-3)
B(-1,5) its symmetric vs. x axis is B'(-1,-5)
C(-3,-3) its symmetric vs. x axis is C'(-3,3)
D(-4,-4) its symmetric vs. x axis is D'(-4,4)
Symmetry vs. the x axis keeps abscises the same & change just the sign of y value
