Answer:
A
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 )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (0, - 2 ) ← 2 points on the line
m = = = -
The line crosses the y- axis at (0, - 2 ) ⇒ c = - 2
f(x) = - x - 2 ← function rule
Answer:
15; -580; 936
Step-by-step explanation:
1. 10a-15=10*3-15=15
2. -5b^3+7b+10=-5*5^3+7*5+10=-580
3. 6abc+4a^2=6*3*5*10+4*3^2=936

Answer:
∠ADB=35°
Step-by-step explanation:
Given arc AB = 70°.
we have to find the angle ∠ADB
Here, Angle subtended by arc AB at O is ∠AOB = 70°
By the theorem,
The angle subtended by an arc at the center is double the angle subtended by it at any point on the remaining part of the circle.
∴ ∠AOB=2(∠ADB)
⇒
hence, angle subtended at the circumference is 35°
