Answers

Answer 1
Answer:

Answer:

r < 3/2 or r < 1.5

Step-by-step explanation:

-8r - 9 > 21

-8r > -21 +9

-8r > -12

divide both sides by -8

= r < 3/2 or 1.5

When are two angles called complements of one another? a. when together they are equal to 180 degrees c. when together they are equal to an acute angle b. when together they are equal to a right angle d. when together they are equal to an obtuse angle

Answers

hola!

Two angles are said to be complements of one another only when:
→ Makes a right angle
→ They add to 90 degrees

Thus,
According to above. statement!

Option [ B ] :
When together they are equal to a right angle is CORRECT!

hope it helps!
b.) complementary angles add up to 90 degrees

PLEASE ANSWER!!!!!!!! Which system of equations does this graph represent? Linear graph and parabola. They intersect at 2, negative 1 and negative 3, 4 (1 point) A. y = x2 − 5 y = −x + 1
B. y = x2 − 5 y = −x − 1
C. y = x2 + 5 y = −x + 1
D. y = x2 + 5 y = −x − 1

Answers

Answer:

Option (A)

Step-by-step explanation:

For equation of the line,

Let the equation is, y = mx + b

Slope 'm' of the line passing through two points (-3, 4) and (2, -1),

m = (y_2-y_1)/(x_2-x_1)

   = (4+1)/(-3-2)

   = -1

y-intercept of this line, b = 1

Now we substitute these values in the equation,

y = -x + 1

Let the equation of the parabola is,

y = a(x - h)² + k

Here, (h, k) is the vertex of the parabola,

Since vertex of the given parabola is (0, -5),

then the equation will be,

y = a(x - 0)²- 5

y = ax² - 5

Since a point (2, -1) lies on this parabola,

-1 = a(2)² - 5

5 - 1 = 4a

a = 1

Equation of the parabola will be,

y = x² - 5

Therefore, Option (A) will be the answer.
