The number of oranges sold by a local market in August can be represented by the function p(x) 28x + 15 and the number of apples sold by the same market in August can be represented
by the function q(2) 12 + 32x, where x represents the number of days the market was open that
month.
Which function, r(x), represents the total number of oranges and apples sold by the market during
the month of August?
r(x) = 60x+27
r(x) = 47x +20
r(x) = 40x +47
r(x) = 42x +3
r(x) = 42 + 3

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
