Answer:

a + b =1

Step-by-step explanation:

Write the given quadratic as x^2 – 1x – 90 = 0.  This factors into

(x - 10)(x + 9) = 0, and so the roots/solutions are {-9, 10}.

If we call -9 "a" and 10 "b," then the sum a + b is -9 + 10, or a + b =1.

PLEASE SOME ONE HELP <br><br> find the values of x and y <br> step by step if possible
vlada-n [284]

Answer:

11. 16x +(9x+5)= 180

25x + 5 = 180

25x= 175

x= 7

If x is 7, then the top value is equal to the bottm one becuase they are vertical angles.

112 + 4y= 180

4y = 68

y= 17

Step-by-step explanation:

12. 6x - 11 + 2x - 9= 180

8x - 20= 180

8x= 200

x= 25

6(25) - 11= 139

20y + 19 = 139

20y = 120

y=6

What is the answer to this question plss and thank you
cluponka [151]

A defines the function

f(1) = - 8 ×( \frac{5}{2} )^{0} = - 8 × 1 = -8

f(2) = - 8 ×( \frac{5}{2}) ^{1} = - \frac{(8.5)}{2}= - 20

f(3) = - 8 ×( \frac{5}{2}) ^{2} = - 8 × \frac{25}{4} = - 50

f(4)= - 8 ×( \frac{5}{2}) ^{3} = - 8 × \frac{125}{8} = -125

f(5) = - 8 ×( \frac{5}{2}) ^{4} = - 8 × \frac{625}{16} = - \frac{625}{2}
