zhannawk [14.2K]

Answer:

Any points on the line y=2/5 x - 6/5. See picture below.

Step-by-step explanation:

Convert the equation to slope intercept form and graph it.

2x - 5y = 6

-5y = 6 - 2x

y = -2/-5 x + 6/-5

y=2/5 x - 6/5.

Locate each of the points listed on the graph. If they are a part of the line, then they are solutions.

Answer:

C. 57°

Step-by-step explanation:

All triangles have a sum of 180°.

m∠D + m∠E + m∠F = 180°

35° + m∠E + 88° = 180°

123° + m∠E = 180°

m∠E = 57°

Katie wants to hang a painting in a gallery. The painting and frame must have an area of 45 square feet. The painting is 6 feet
Luda [366]
Each side should increase by 2x (left & right, and up & down) so that to match the condition :
7+2x)(6+2x) = 45
Solving it will give you: 4x² + 26x - 3

Answer:

a = - \frac{9}{2} , b = - \frac{25}{4}

Step-by-step explanation:

To obtain the required form use the method of completing the square

add/ subtract ( half the coefficient of the x- term)² to x² - 9x

y = x² + 2(- \frac{9}{2} )x + \frac{81}{4} - \frac{81}{4} + 14

  = (x - \frac{9}{2} )² - \frac{81}{4} + \frac{56}{4}

  = (x - \frac{9}{2} )²- \frac{25}{4} ← in the form (x + a)² + b

with a = - \frac{9}{2} and b = - \frac{25}{4}

Which best describes the equation that the graph represents?
andreev551 [17]

Answer:

y= \frac{9}{5}x

Step-by-step explanation:

Given the two points:

  • Origin (x1, y1) = (0, 0)
  • The point (x2, y2) = (5, 9)

Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).

=>Time, x the independent variable,and distance is the dependent variable.

We have the standard form of a linear equation is:

y= mx + b where a is the slope

We know that, the slope of the function is:

m = \frac{y2-y1}{x2-x1}

In this situatuon, m = \frac{9-0}{5-0} = \frac{9}{5}

=> y= \frac{9}{5}x + b(1)

The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:

0 = \frac{9}{5}*0 + b

<=> b = 0

So our equation that the graph represents is: y= \frac{9}{5}x
