You are playing a video game. For each diamond you collect, you earn 110 points. You also earn 80 bonus points by completing the
sashaice [31]

Answer:

110d + 80 > 1620

d > 14

Step-by-step explanation:

The amount of points from collecting diamonds can be represented by 110d, since you get 110 points for each diamond, d

Add 80 to this to represent the bonus points.

Use a greater than inequality, because you have to get more than 1620 points.

Put this all together:

110d + 80 > 1620

Then, solve for d:

110d + 80 > 1620

110d > 1540

d > 14

So, you have to collect more than 14 diamonds in less than 2 minutes in order to advance to the next level.

Write the equation of the line with the following characteristics.
Alika [10]

Answer:

y = 7x

y = 2x -3

y = 3

x = -2

Step-by-step explanation:

  • <em>Slope-intercept form: y= mx+b</em>
  • <em>Parallel lines have same slope</em>

a)Parallel to y=7x+2 through the point (0,0)

<u> This line will have a form:</u>

  • y= 7x + b

<u>Considering the given point of (0,0), to find the value of b:</u>

  • 0= 7*0+b ⇒ b =0

<u>The line is: </u>

  • y = 7x

b)Slope of 2 through the point (0,−3)

<u> Solving as above:</u>

  • y= 2x + b
  • -3 = 2*0 + b ⇒ b = -3
  • y = 2x -3

c)A horizontal line through the point (0,3)

<u> A horizontal line will have constant value for y for any value of x:</u>

  • y = 3

d)A vertical line through the point (−2,0)

<u>A vertical line will have constant value of x for any value of y:</u>

  • x= -2

Name the algebraic property demonstrated in the example below: If x = 3 and 3 = y, then x = y.
NemiM [27]
Its the transitive property. Transitive means that is a=b and b=c then a=c. It matches with what they're asking for.

Use the slope formula to find the slope. y2 -4 y1 2 x2 0 x1 2 m=ΔyΔx=y2−y1x2−x1 Usetheslopeformula m = Δ y Δ x = y 2 - y 1 x 2 -
jenyasd209 [6]

Answer:

The slope is, 3

Step-by-step explanation:

Formula for slope(m) is given by:

m = \frac{\triangle y}{\triangle x}

or

m = \frac{y_2-y_1}{x_2-x_1}           .....[1]

Given the statement:

y_2 = -4

y_1 = 2

x_2 = 0 and x_1 = 2

Substitute these given values in [1] we have;

m = \frac{-4-2}{0-2} = \frac{-6}{-2}  

Simplify:

m = 3

Therefore, the value of slope is, 3
