Mathematics
1 answer:
Firlakuza [10]3 years ago
8 0

consider first number is = x

formula,

(n / 2)(first number + last number) = sum,

7/2(x+x+6)= 945

2x+6= 945×2/7

2x+6 = 270

2x= 270-6

x=264/2= 132

Answer the smallest number is 132.

Write and graph an equation that is perpendicular to the equation x-3y=6 and through point (2,-3)
Korvikt [17]

Answer:

y = mx + b   is slope-intercept form of the linear equation.

y - y1 = m(x - x1)   is point-slope form of the linear equation.

Ax + By = C  (A ≥ 0)   is standard form of the linear equation.

How can you identify a linear nonproportional relationship from a table, a graph, and an equation?
Zarrin [17]
On-proportional linear relationships can be expressed in the form y = mx + b, where b is not 0, m represents the constant rate of change or slope of the line, and b represents the y-intercept. The graph of a non-proportional linear relationship is a straight line that does not pass through the origin.

Find the coordinates of the turning point for the equation of the graph below y=x^2+14x+45
USPshnik [31]

Answer:

(- 7, - 4 )

Step-by-step explanation:

Given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the turning point is

x = - \frac{b}{2a}

y = x² + 14x + 45 ← is in standard form

with a = 1, b = 14 , then

x = - \frac{14}{2} = - 7

Substitute x = - 7 into the equation and evaluate for y

y = (- 7)² + 14(- 7) + 45 = 49 - 98 + 45 = - 4

coordinates of turning point = (- 7, - 4 )
