Answer:
Step-by-step explanation:
Given the inequality:
Step 1: Distribute the bracket
Step 2: Subtract 10 from both sides
Step 3: Divide both sides by -2
Note that when you divide an inequality by a negative sign, the inequality sign is reversed.
Parallel lines have the same slope but different y intercepts
Slope: 4
y=4x+b
this is the new equation, plug in the point
-10=4(-1)+B
-10=-4+B
add 4
-6=B
Y intercept= -6
slope; 4
Answer:
Diameter = 53.41 m
Step-by-step explanation:
2517/15 = 167.8 (circumference)
D=(C/pi)
C/pi = 53.41
D= 53.41
The parabola vertex is (1,5), the focus of the parabola is (1,6), and the directrix y = 4.
<h3>What is the graph of a parabolic equation?</h3>
The graph of a parabolic equation is a U-shape curve graph that is established from a quadratic equation.
From the given information:
The vertex of an up-down facing parabolic equation takes the form:
y = ax² + bx + c is
Rewriting the given equation:
Replacing the value of x into the equation, y becomes:
Thus, the parabola vertex is (1,5)
From the vertex, the focus of the parabola is (1,6), and the directrix y = 4.
The graphical representation of the parabola is seen in the image attached below.
