Answer:
D.
Step-by-step explanation:
To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.
What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5
B.
left = -5 - 5 = -10
right = -(2/3)(4 + 4) = -16/3
So it's D. Let's verify:
D.
left = -5 + 5 = 0
right = -(2/3)(4 - 4) = 0
Checks out.
Answer:
Option D
Step-by-step explanation:
→ Find the gradient of the parallel line
[tex]y=-\frac{2}{3} x+c[/tex]
→ Substitute in the coordinates as x and y values to find c
[tex]5=-\frac{2}{3} *-4+c[/tex]
→ Simplify
[tex]5=\frac{8}{3} +c[/tex]
→ Minus [tex]\frac{8}{3}[/tex] from both sides to find c
[tex]c = \frac{7}{3}[/tex]
→ Expand out all options and then see which one contains all the numbers above
Option D

In one day, Ricardo hiked 2_ 2 3 times as far as Bernie and Chloe hiked before they ate lunch. How far did he hike?
Answers
Complete question :
Bernie and Chloe hiked the Tremont Trail to the end and back. Then they hiked the Wildflower trail to the end before stopping to eat lunch. Before Ricardo ate his lunch, he hiked 2 2/3 times as far as Bernie and Chloe. How far did he hike?
Required diagram is attached below
Answer:
25 miles
Step-by-step explanation:
Tremont Trail = 3 1/2 miles
Wildflower trail = 2 3/8 miles
Distance covered ; Tremont Trail and back : (3 1/2 * 2). = 7/2 * 2 = 14 /2 = 7 miles
Total distance covered by Bernie and Chloe before stopping for lunch /
(7 miles + 2 3/8 Miles) = 9 3/8 miles = 75/8 miles
Ricardo's distance = 2 2/3 * Bernie and Chloe's total distance
Ricardo's distance = 8/3 * 75/8 = 600 /24 = 25 miles

Solve 2x + 20 = 6x – 12*
Answers
Answer:
x = 8
Step-by-step explanation:
Given
2x + 20 = 6x - 12 ( subtract 2x from both sides )
20 = 4x - 12 ( add 12 to both sides )
32 = 4x ( divide both sides by 4 )
8 = x
=> 2x + 20 = 6x - 12
=> 20 + 12 = 6x - 2x
=> 32 = 4x
=> x =32/4
=> x = 8solve and get brainliest

Given:
The table of values.
v and x are in direct proportion.
To find:
The formula connecting v and x.
Solution:
(a)
v and x are in direct proportion.
[tex]v\propto x[/tex]
[tex]v=kx[/tex] ...(i)
Where, k is the constant of proportionality.
Putting v=13.6 and x=32.64, we get
[tex]13.6=k(32.64)[/tex]
[tex]\dfrac{13.6}{32.64}=k[/tex]
[tex]\dfrac{5}{12}=k[/tex]
Putting the value of k in (i), we get
[tex]v=\dfrac{5}{12}x[/tex]
Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].
(b)
Putting v=n and x=8.16, we get
[tex]n=\dfrac{5}{12}(8.16)[/tex]
[tex]n=3.4[/tex]
Therefore, the value of n is 3.4.
