3a + b = 54...when b = 9
3a + 9 = 54
3a = 54 - 9
3a = 45
a = 45/3
a = 15 <===

Salutations!

$3a+b = 54$

Replace b as 9

$3a+9=54$

$3a=54-9$

$3a=45$

$a= 45/3$

$a=15$

Thus, your answer is $15$

Hope I helped (:

Have a great day!

Find the equation of the line which is parallel to y = 4x + 3 and goes through the point (4, 5)

skad [1K]

Answer:

y = 4x - 11

Step-by-step explanation:

The given line has a slope m = 4.

We know parallel lines have equal slopes.

<u>Use point - slope equation and substitute the coordinates of the given point to get:</u>

y - 5 = 4(x - 4)
y - 5 = 4x - 16
y = 4x - 16 + 5
y = 4x - 11

A function h(x) is defined by the equation h(x) = sqrt x-2 + 3. Which is the graph of h(x)?

____ [38]

<h3><u>Explanation</u></h3>

Given Equation

$h(x) = \sqrt{x - 2} + 3$

Transformation

A constant inside the square root will make the graph shift either left to right, depending on the number. From the equation. The graph shifts to right two units.

A constant outside the square root will make the graph shift up or down, depending the value. From the equation, the graph shifts up 3 units.

<h3><u>Answer</u></h3>

Second Image, the first one where x = 2 and y = 3.

You roll a 6-sided die with faces numbered 1 through 6, and toss a coin. What is the probability of rolling a 2 or getting heads

tino4ka555 [31]

P(2 or H) = P(2) + P(H) - P(2 and H)

What is the probability of getting a 2 P(2)? = 1/6

What is the probability of getting heads P(H)? = 1/2

P(2 and H) is the product of those two events since the events are independent. = 1/6 * 1/2 = 1/12

P(2 or H) = P(2) + P(H) - P(2 and H)

P(2 or H) = 1/6 + 1/2 - 1/12 = 7/12
