The decimal form of 7 3/5 is 7.6
Answer:
y = (x-0)^2 + (-5) ⇒ y = x^2 - 5
Step-by-step explanation:
The general vertex form of the parabola y = a(x - h)² + k
Where (h,k) is the coordinates of the vertex.
As shown at the graph the vertex of the parabola is the point (0, -5)
So,
y = a(x-0) + (-5)
y = ax^2 - 5
To find substitute with another point from the graph like (1,-4)
So, at x = 1 ⇒ y = -4
-4 = a * 1^2 - 5
a = -4 + 5 = 1
<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>
Set 12x + 13 equal to Angle ZHG plus Angle IHZ. x=10 and the measure of Angle IHG should be 133.
It is given in this question that angle 1 and angle 2 are linear pair .
LInear pair are those angles , whose sum is 180 degree.
That is sum of measurements of angle 1 and angle 2 must be 180 degree. That is
Combining like terms
Subtracting 46 from both sides
Dividing both sides by 2
So the two angles are
Answer:x=−1 or x=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
3(|2x+5|)−9=0
Step 1: Add 9 to both sides.
3(|2x+5|)−9+9=0+9
3(|2x+5|)=9
Step 2: Divide both sides by 3.
3(|2x+5|)
3
=
9
3
|2x+5|=3
Step 3: Solve Absolute Value.
|2x+5|=3
We know either2x+5=3or2x+5=−3
2x+5=3(Possibility 1)
2x+5−5=3−5(Subtract 5 from both sides)
2x=−2
2x
2
=
−2
2
(Divide both sides by 2)
x=−1
2x+5=−3(Possibility 2)
2x+5−5=−3−5(Subtract 5 from both sides)
2x=−8
2x
2
=
−8
2
(Divide both sides by 2)
x=−4
Answer: x=−1 or x=−4
