Step-by-step explanation:

Step 1: Define

3x + 6(x - 11) = 5x - 18

Step 2: Solve for x

Distribute 6: 3x + 6x - 66 = 5x - 18
Combine like terms: 9x - 66 = 5x - 18
Isolate x terms: 4x - 66 = -18
Isolate x term: 4x = 48
Isolate x: x = 12

MATH HELP!!!!! If y = 15 when x = 2, what is the value of x when y = 7?

Ede4ka [16]

Direct Variation: $\frac{y}{x} = k$

$\frac{15}{2} = k$

when y = 7: $\frac{7}{x} = \frac{15}{2}$

14 = 15x

$\frac{14}{15} = x$

Inverse variation: y*x = k

15 * 2 = k

30 = k

when y = 7: 7 * x = 30

$x = \frac{30}{7}$

Answer:

A = 38°

Step-by-step explanation:

We are going to use cosine law to find angle A where

a = 4.7

b = 3.9 m

c = 2.9 m

${c}^{2} = {a}^{2} + {b}^{2} - 2ab \cos( \alpha )$

$\cos( \alpha ) = \frac{ {a}^{2} + {b}^{2} - {c}^{2} }{2ab}$

cos A = [(4.7)^2 + (3.9)^2 - (2.9)^2]/2(4.7)(3.9)

= 28.89/36.66

= 0.788

A = arccos(0.788) = 38°

Ive labeled the ordered pairs but what does it mean by state the quadrant or axis in/on which the point is located

irina1246 [14]

So the image below shows what quadrants are. From the top-right square, the order of quadrants goes from 1-4 in a counter-clockwise matter.

Quadrant I: Top-right square

Quadrant II: Top-left square

Quadrant III: Bottom-left square

Quadrant IV: Bottom-right square.

Any points that are on the bolded vertical line are on the y-axis, and any points on the bolded horizontal line is on the x-axis.
