If z varies jointly with x and y, x = 2 and y = 2, z = 7. Find z when x = 4 and y = 8.
Wittaler [7]

Answer:

56

Step-by-step explanation:

z varies jointly with x and y:

z = kxy

When x = 2 and y = 2, z = 7.

7 = k(2)(2)

k = 7/4

z = 7/4 xy

When x = 4 and y = 8:

z = 7/4 (4)(8)

z = 56

Using the slope and the y-intercept graph the line represents by the following equation then select the correct graph 2y + 4 =0
dybincka [34]

Answer:

Step-by-step explanation:

2y + 4 = 0               <em>subtract 4 from both sides</em>

2y = -4       <em>divide both sides by 2</em>

y = -2

The slope-intercept form of an equation of a line:

y = mx + b

m<em> - slope</em>

b<em> - y-intercept → (0, </em><em>b</em><em>)</em>

In the equation

y = -2

<em>slope: </em><em>m = 0</em>

<em>y-intercept: </em><em>b = -2 → (0, -2)</em>

<em />

<em>y = -2 - it's a horizontal line</em>

Given triangle DEF where ∠D = (7b +1)∘, ∠E = (2b + 1)∘, and ∠F = ( b + 8)∘. What is the measure of ∠E?
____ [38]
<h3>Answer:  35 (choice C)</h3>

=============================================

Explanation:

For any triangle, the three interior angles always add to 180.

D+E+F = 180

(7b+1) + (2b+1) + (b+8) = 180

(7b+2b+b) + (1+1+8) = 180

10b+10 = 180

10b = 180-10

10b = 170

b = 170/10

b = 17

Use this value of b to find the three angle measures

  • D = 7b+1 = 7*17+1 = 119+1 = 120
  • E = 2b+1 = 2*17+1 = 34+1 = 35 degrees
  • F = b+8 = 17+8 = 25

As a check,

D+E+F = 120+35+25 = 120+60 = 180

which helps confirm the correct answers.
