Please solve with explanation

Q * 0.25 + D * 0.10 = $290.05

Q + D = 1234

so

Q = 1234 - D

therefore

(1234 - D) * 0.25 + D * 0.10 = 290.05

308.50 - 0.25D + 0.10D = 290.05

18.45 = 0.15D

D = 123

Q = 1111

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
