F(x) = 2x + 3
f(a) = 2a + 3
when f(a) = 11
11 = 2a + 3
therefore 2a = 8 
 and a = 4

valentinak56 [21]

Answer: -\frac{2}{25}a^{3}x^{3}

Step-by-step explanation:

1. The problem asked for the product of \frac{2}{5}a^{2}x and -\frac{1}{5}x^{2}a, therefore, you must mutliply them, as you can see below:

2. According the exponents propertiess, when you have a multiplication of two powers that has the equal base, you must add the exponents. THerefore, you have the following result:

 (\frac{2}{5}a^{2}x)(-\frac{1}{5}x^{2}a)=-\frac{2}{25}a^{3}x^{3}

Please help me! Write an equation in point-slope form of the line that passes through the given point and has the given slope.
andriy [413]

9514 1404 393

Answer:

  1. y -3 = 5(x -1)
  2. y +1 = -3(x +2)
  3. y +7 = -1/4(x -4)

Step-by-step explanation:

When you are given a point and a slope, and asked for the equation in point-slope form, it is simply a matter of putting the given numbers into the appropriate places in the equation template.

  y -k = m(x -h) . . . . . . point (h, k), slope m

__

1. y -3 = 5(x -1) . . . . . . point (1, 3), slope 5

2. y +1 = -3(x +2) . . . . point (-2, -1), slope -3

  note that for k=-1, -k = -(-1) = +1; similarly the value of -h becomes +2

3. y +7 = -1/4(x -4) . . . point (4, -7), slope -1/4
