Rx+h=sx-k solve for x

1 answer:

6 0

Rx + h = sx - k Take all with x to the LHS

Rx - sx = -k - h

x(R - s) = - k -h

x = (-k - h) / (R - s). Multiply top and bottom by -1.

x = (k + h) / (s - R)

In the xy- plane, the graph of the equation y + 3x + 5 is a line that intersects the y-axis at (0,b) what is the value of b?

maxonik [38]

Answer:

$b=5$

Step-by-step explanation:

The given equation is:

$y=3x+5$

To find the point where this line intersect the y-axis, we put x=0 into the given equation.

When x=0, we have $y=3(0)+5$ .

This implies that; y=5.

The y-intercept is (0,5).

Comparing (0,5) to (0,b), we can conclude that; b=5

David's bowling score is 6 less than 2 times Aaron's score. The sum of their scores is 84. Find the score of each student. Use t

Y_Kistochka [10]

Answer:

Aaron's bowling score is 30

David's bowling score is 54

Step-by-step explanation:

The variable representing Aaron's score is = a

The variable representing David's bowling score = d

The sum of their scores is 84.

= a + d = 84...... Equation 1

David's bowling score is 6 less than 2 times Aaron's score.

d = 2a - 6

Substituting 2a - 6 for d in Equation 1

a + 2a - 6 = 84

3a - 6 = 84

3a = 84 + 6

3a = 90

a = 90/3

a = 30

Hence, Aaron's bowling score is 30

d = 2a - 6

d = 2(30) - 6

d = 60 - 6

d = 54

David's bowling score is 54
