Graph of which exponential function passes through the points (0,4) and (1,24)?​
gavmur [86]

Answer:

see explanation

Step-by-step explanation:

The exponential function is of the form

y = a b^{x}

Substitute the given points into the equation to find a and b

Using (0, 4), then

4 = ab^{0} ⇒ a = 4

Using (1, 24), then

24 = 4 b^{1} ⇒ b = 6

Exponential function is

y = 4 × 6^{x}

Which symbol makes the comparisons true ? Complete the comparison -6 ? 3
Usimov [2.4K]
<h3>Hello!</h3>

======================================

Negative numbers are always less than positive ones.

Do you remember the symbol for "less than"? That's right, "<" :)

Hence,

-6<3

Because

-6 is negative (the - sign tells us that)

3 is positive

Which of the following is the equation of a line perpendicular to the line
Taya2010 [7]

Answer:

  • A. - 2x + 3y = 21

Step-by-step explanation:

The perpendicular lines have opposite reciprocal slopes.

<u>The given line has a slope of:</u>

  • m = -3/2

<u>The perpendicular slope is:</u>

  • m = 2/3

<u>And its y-intercept is:</u>

  • 9 = 2/3*3 + b
  • b = 7

<u>The line is:</u>

  • y = 2/3x + 7

<u>Convert this into standard form and compare with answer choices:</u>

  • 3y = 2x + 21
  • - 2x + 3y = 21

Correct choice is A
