Solve y
Ksivusya [100]

The value of y in -3 = 7\left(y-\dfrac97\right) is 6/7

<h3>How to solve for y?</h3>

The equation is given as:

-3 = 7\left(y-\dfrac97\right)

Open the bracket

-3 = 7y - 9

Add 9 to both sides of the equation

7y = 6

Divide both sides by 7

y= 6/7

Hence, the value of y in -3 = 7\left(y-\dfrac97\right) is 6/7

Caleb has an assignment to draw a contour map. What type of landform is he most likely drawing?
marysya [2.9K]

The type of land form that Caleb most likely draws is a hill. The answer is option C- a hill.

Step-by-step explanation:

  • Contour lines are <u>drawn to represent the changes in the elevation</u> which helps to know the slope of the figure drawn.
  • If the contour lines are drawn close, then steeper the figure is. And more distant the lines are drawn, then less steep the figure is.
  • Here, the lines seem to be likely circle in shape. The distance of the outermost contour line is 20 ft. The <u>next inner lines will have reduced values of 20 ft.</u>
  • Therefore, <u>the elevation gets reduced from higher to lower points</u> which provides a diagram of a hill. Since there is no continuous high and low elevations, this cannot be a valley (a range of mountains).
  • Furthermore, The contour diagram for option A and D such as creek(water stream) or shoreline will have different and mixed values of elevations that seems to be a messy structure of contour lines.
