J + p + m = 39
m = 4p ....m = 4(j - 3)....m = 4j - 12
p = j - 3

j + j - 3 + 4j - 12 = 39
6j - 15 = 39
6j = 39 + 15
6j = 54
j = 54/6
j = 9 <== justin

m = 4j - 12
m = 4(9) - 12
m = 36 - 12
m = 24 <=== matt

p = j - 3
p = 9 - 3
p = 6 <===peyton

Given the linear equation, 2x +4= 6, find the rate, initial value, and specific value.
kap26 [50]

Answer: B. The rate is 2, the initial value is 4, and the specific value is 6.

Step-by-step explanation:

for a linear function y = a*x + b

Rate = coefficient that is multiplicating the variable. ( a in this case)

Initial value = value taken of y, when we have x = 0 (b in this case)

Specific value = value forced on y.

In this case, we have:

y = 6 = 2*x + 4

Then:

The coefficient multiplicating x is 2, so the rate is 2.

The constant term is 4, so the initial value is 4.

The value equal to y is 6, so the specific value is 6.

The correct option is B.

5p-3r=1
Brilliant_brown [7]
If you would like to solve the system of equations, you can do this using the following steps:

5p - 3r = 1     /*2
8p + 6r = 4
__________
10p - 6r = 2
<span>8p + 6r = 4
</span>__________
10p - 6r + 8p + 6r = 2 + 4
18p = 6
p = 6/18
p = 1/3

<span>5p - 3r = 1
</span>5 * 1/3 - 3r = 1
5/3 - 3r = 1
5/3 - 1 = 3r
5/3 - 3/3 = 3r
2/3 = 3r
r = 2/9

(p, r) = (1/3, 2/9)

The correct result would be <span>(1/3, 2/9)</span>.
