Answer:

Complementary angles

Step-by-step explanation:

When two angles add up to 90°, they are Complementary to each other.

Here, ∠DAB = 90° (right angles)

It means, ∠DAB = ∠BAE (vertically opposite angles)

Also, ∠BAE = a + b

So, a+b is equal to 90°. Hence, the correct option is (b) "Complementary angles".

Identify the x-intercept and y-intercept of the equation below.
Radda [10]

Answer:

x intercept at (7/3 , 0)

y intercept at (0,-3)

Step-by-step explanation:

9x-7y=21

we need to find x  and y intercepts

To find x intercept , plug in 0 for y

9x - 7(0) = 21

9x = 21

divide by 9 on both sides

x= 21/ 9 = 7/3

so x intercept at (7/3 , 0)

To find y intercept , plug in 0 for x

9(0) - 7(y) = 21

-7y = 21

divide by -7 on both sides

y= -3

so y intercept at (0,-3)

Multiply or Divide<br><br> (i need this for school tomorrow)
lions [1.4K]

Answer:

Ok so here are the simple rules of doing it (very easy) cause I’m not doing it all so . when multiplying a power with The same base keep the base but add the exponents. Dividing, keep the base (if their the same if not then its already simplified same with multiplication) but SUBTRACT the exponents. Also keep the parenthesis if it’s a negative number base.

I’ll do a few.

11) a^10.           11b) 5^4

12) (-2)^2.        

13) 10^2.          13b) s^6

14) -4s^5(t^6) <- [Im not sure of this one)

15) x^3(y^3)
