Answer: 46.8
Step-by-step explanation:
Answer:
slope intercept: y=mx+b
m=slope
b=y intercept
y= -12x+1/2
Step-by-step explanation:
The larger number is 13 and smaller number is 4
<em><u>Solution:</u></em>
Let the larger number be "a"
Let the smaller number be "b"
<em><u>Given that larger of two numbers is twice the smaller increased by five</u></em>
larger number = twice the smaller increased by five
larger number = twice the smaller number + 5
a = 2b + 5 --- eqn 1
<em><u>Also given that three times the larger exceeds double the smaller by 31</u></em>
Here "exceeds" denotes addition and "times" denotes multiplication
"double" denotes being multiplied by 2
three times the larger number = double the smaller number + 31
3a = 2b + 31 ---- eqn 2
<em><u>Let us solve eqn 1 and eqn 2 to find values of "a" and "b"</u></em>
Substitute eqn 1 in eqn 2
3(2b + 5) = 2b + 31
6b + 15 = 2b + 31
6b - 2b = 31 - 15
4b = 16
<h3>b = 4</h3>
From eqn 1,
a = 2b + 5
a = 2(4) + 5
a = 8 + 5
<h3>a = 13</h3>
Thus the larger number is 13 and smaller number is 4
The solution for x in the equation 3ax - n/5 = -4 is x = -4/3a + n/15a.
<h3>What is the solution for x in the given equation?</h3>
3ax - n/5 = -4
To solve for x, isolate the term that contains x.
3ax - n/5 = -4
3ax = -4 + n/5
Divide each term by the coefficient of x and simplify
3ax/3a = -4/3a + (n/5)/3a
x = -4/3a + (n/5)/3a
multiply (n/5) by the reciprocal of 3a
x = -4/3a + (n/5) × 1/3a
x = -4/3a + n/15a
Therefore, the solution for x in the equation 3ax - n/5 = -4 is x = -4/3a + n/15a.
