Answers
Answer:
second table
Step-by-step explanation:
For a proportional relationship, the constant of proportionality k is
k = [tex]\frac{y}{x}[/tex]
Choose an ordered pair from each table and evaluate for k
Table 1
using (8, 1 ), then
k = [tex]\frac{1}{8}[/tex] = 0.125 ≠ 0.8
Table 2
using (10, 8 ), then
k = [tex]\frac{8}{10}[/tex] = 0.8
Table 3
using (8, 0.8 ), then
k = [tex]\frac{0.8}{8}[/tex] = 0.1 ≠ 0.8
Table 4
using (10, 20.8 ), then
k = [tex]\frac{20.8}{10}[/tex] = 2.08 ≠ 0.8
Table 2 has a constant of proportionality k = 0.8

The raito of chocolate covered carmels to choclate corvered cherries in my vault is 5 to 2 if i have 84 choclate covereds cherries how many choclate covered caramels do i have
Answers
Answer: 1 have 210 chocolate covered caramels
Step-by-step explanation:
step 1
The ratio of chocolate covered caramels to chocolate covered cherries in my vault is 5 to 2 which can also be written as 5:2
But the number of chocolate covered cherries =84
Total ratio is given as 5+2 = 7
Step 2
such that the total number of chocolate i had would be gotten from
Ratio of chocolate covered cherries/ total ratio x Total chocolates = Number of chocolate covered cherries. Let X = Total number of chocolates
2/7 x X = 84
x= 84 x 7 / 2 =294
Therefore The number of chocolate covered caramels= ratio of chocolate covered caramels/ total ratio x Total chocolates =
5/7 X 294= 210

Answer:
x=5
Step-by-step explanation:
We know that corresponding sides will have the same angles. In this case it's 12 and 12+3=15. That means that larger triangle is 15/12=5/4=1.25 times larger.
So we apply that for 3x+1 as well.
1.25(3x+1)=4x
3.75x+1.25=4x
.25x=1.25
x=5

The piecewise function h(x) is shown on the graph.
On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 4, negative 4) and goes up to an open circle at (negative 1, 2). The second line has a closed circle at (negative 1, 3), continues horizontally to (1, 3), and then goes down to a closed circle at (4, 0).
What is the value of h(3)?

Answers
Step-by-step explanation/Answer:
The value for h(3) is 1.
Coordinate (3,1)
The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.
So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:
Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.

Answers
Answer:
[tex]y=-\frac{1}{5}x+\frac{6}{5}[/tex]
Step-by-step explanation:
Let's solve for x.
[tex]x+5y=6[/tex]
Step 1: Add -5y to both sides.
[tex]x+5y+-5y=6+-5y[/tex]
[tex]x=-5y+6[/tex]
Answer:
[tex]x=-5y+6[/tex]
Let's solve for y.
[tex]x+5y=6[/tex]
Step 1: Add -x to both sides.
[tex]x+5y+-x=6+-x[/tex]
[tex]5y=-x+6[/tex]
Step 2: Divide both sides by 5.
[tex]\frac{5y}{5}=\frac{-x+6}{5}[/tex]
[tex]y=\frac{-1}{5} x+\frac{6}{5}[/tex]
Answer:
[tex]y=\frac{-1}{5} x+\frac{6}{5}[/tex]
