(ax + 1)(4x^2 - bx + 5) = 2x^2 - 13x +5
If the equation above is true for all real values of x, what is b?

for the points

step-by-step explanation:

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

add a pic of the graph, then ill edit this "answer" and solve it for you : 3

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
