Answer: B

Step-by-step explanation:

When adding and subtracting fractions, the denominator must be the same. Since the denominator is the same, we can directly subtract the numerator.

$\frac{x^2-7-(2x+9)\\}{5x-4}=\frac{x^2-7-2x-9}{5x-4}$

How many photons with 10 ev are required to produce 20 joules of energy?

alexira [117]

1 joule = 6,242e+18ev

20 joule = 20 joule *6,242e+18 ev/joule =1,248e+20 ev

1,248e+20 ev / (10 ev / photon) =1,248e+19 photons.

[CORRECT ANSWER RECEIVES BRAINLIEST ONLY

sammy [17]

Answer:

step 2

Step-by-step explanation:

The student first made an error in the step 2.

Because if we simplify the equation A in step 1, we should distribute the right side of the equation following the rule a(b-c) = a*b +a*(-c)

So, it would be

–7y = (-7)*(16)+(-7)*(-2z)

=> -7y = -112 + 14z

Write the equation in slope intercept form. what is the slope and y intercept. -9x+10y=-9

Svet_ta [14]

Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.

So firstly, add both sides by 9x: $10y=9x-9$

Next, divide both sides by 10 and <u>your slope-intercept form is $y=\frac{9}{10}x-\frac{9}{10}$ </u>

Now looking at our slope-intercept form equation, <u>the slope is 9/10 and the y-intercept is (0, -9/10).</u>
