Answer:
y = -4x - 16 or y +4x + 16 = 0
Step-by-step explanation:
Gradient (m) = -4
Equation of a line given gradient and one point=
y - <em>y </em>= m(x - <em>x)</em><em> </em>where (<em>x </em>, <em>y </em>) are the coordinates of the point.
Substituting...
y -(-4) = -4(x -(-3))
y + 4 = -4(x + 3)
y + 4 = -4x - 12
y = -4x - 12 - 4
y = -4x - 16 or y +4x + 16 = 0
The statement is false, because radian measure does not depend on the radius of a circle.
<h3>
What is radian measure?</h3>
Radian measure is defined as the angle subtended at the center by an arc of length 1 unit in a unit circle.
Radian measure depends on the length of arc of a circle, since it increases as the arc length increases and decreases as the arc length decreases.
<h3>What is arc length?</h3>
Arc length is defined as the distance along the part of the circumference of any circle.
Thus, we can conclude that the statement is false, because radian measure does not depend on the radius of a circle.

Step 1: Simplify both sides of the inequality.
Step 2: Subtract 7 from both sides.
Answer:
880
Step-by-step explanation:
the train travels=220km in 4 hours
therefore, multiply 220 and 4
=220 x 4 = 880
so, the train travels 880 km in 9 hours
HAVE A GREAT DAY!
Answer:
Savings of Jeff will be $140.
Step-by-step explanation:
List price of TV = $700
Now, it is given that, this TV is available at 20% off or 20% discount during the President's week.
So, rate of discount = 20%
Now, discount = 20% of $700
= $140
Now, the discount of $140 is the amount of money that Jeff saves if he buys the TV on President's Day.
