Step-by-step explanation:
rise / run . the line is decreasing vertically by 3 and increasing horizontally by 2.
Answer:
To determine if a proportional relationship exists look for the data to lie on a straight line passing through the origin. to examine the ratio y/x (instead of x/y).
Step-by-step explanation:
Hope this helps! :)
Answer:
1/12 kg
Step-by-step explanation:
The 3/4 kg of sweets is split into 9 parts, so
(3/4)/9 = 1/12 kg
Answer: It is said to be an obtuse angle.
Step-by-step explanation:
Angles under 90 degrees are called acute angles.
Angles that are equivalent with 90 degrees are right angles.
Angles that measure more than 90 degrees but under 180 degrees are called obtuse.
Angle that have the same measure as 180 degrees are straight angle.
Answer:
x = -5
Step-by-step explanation:
We can use the below formula to find the line of symmetry.
( x - a )² + b
Here,
line of symmetry = +a
Vertex = +b
And now let us take a look at the given equation.
y = x² + 10x + 22
To find the line of symmetry from the given equation we have to make the given equation as the given formula.
Let us use the completing square method for that.
y = x² + 10x + 22
<em>Put zero instead of y.</em>
x² + 10x + 22 = 0
x² + 10x = -22
x² + 10x + 25 = -22 + 25
( x + 5 )² = 3
( x + 5 )² -3 = 0
Therefore,
line of symmetry of the line is = -5
∴ x = -5
