Answer:
33 cm²
Step-by-step explanation:
Area of triangular prism: A = ((1.5 x 2) /2) x 2 + 5 x 2.5 + 5 x 2 + 5 x 1.5
A = 3 + 12.5 + 10 + 7.5 = 33
Answer:
y = - 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (- 2, - 1) into the partial equation
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = - 3x - 7 ← equation of line
Y=7 or 7y tell me if this right
