Answer: C
Step-by-step explanation: devision?
An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Answer: the most straight-forward way to prove this is to plug -5 in the equation as the value of x. If the the equality holds, it is proven that x=-5:
3x+1=-14 | use x=-5
3(-5)+1=-14
-15+1=-14
-14=-14 --> equality holds --> x=-5 is a solution to 3x+1=-14
Answer: BXC =70°
Step-by-step explanation:
XBC= isosceles so XBC=XCB
XBC=55° (isosceles triangle)
BXC+XBC+XCB=180° (angles in a triangle =180°)
BXC=180°- (55°+55°)
BXC=180°-110°
BXC=70°
Answer:
x-intercept : (2, 0)
y-intercept : (0, -5)
Step-by-step explanation:
The x-intercept is where y = 0, and the y-intercept is where x = 0. To find the intercepts, substitute a zero in for the other variable, and solve.
So the x-intercept of 5x – 2y = 10 is
5x – 2y = 10 → 5x – 2(0) = 10 → 5x = 10 →
x = 2 → (2, 0).
So the y-intercept of 5x – 2y = 10 is
5x – 2y = 10 → 5(0) – 2y = 10 → -2y = 10 →
y = -5 → (0, -5).
