Consider the system of equations.
x-3y = 9
1/5 x - 2y = -1
Which number can be multiplied by the second equation to eliminate the x-variable when the equations are added
together?
Given:
The system of equations:
[tex]x-3y=9[/tex]
[tex]\dfrac{1}{5}x-2y=-1[/tex]
To find:
The number that can be multiplied by the second equation to eliminate the x-variable when the equations are added together.
Solution:
We have,
[tex]x-3y=9[/tex] ...(i)
[tex]\dfrac{1}{5}x-2y=-1[/tex] ...(ii)
The coefficient of x in (i) and (ii) are 1 and [tex]\dfrac{1}{5}[/tex] respectively.
To eliminate the variable x by adding the equations, we need the coefficients of x as the additive inverse of each other, i.e, a and -a So, a+(-a)=0.
It means, we have to convert [tex]\dfrac{1}{5}[/tex] into -1. It is possible if we multiply the equation (ii) by -5.
On multiplying equation (ii) by -5, we get
[tex]-x+10y=5[/tex] ...(iii)
On adding (i) and (iii), we get
[tex]7y=14[/tex]
Here, x is eliminated.
Therefore, the number -5 can be multiplied by the second equation to eliminate the x-variable.

to understand thisyou need to know about:algebraPEMDASlet's solve:given function:
[tex] \quad \rm\: f(x) = - 2x +8[/tex]
when x is 0
[tex] \sf \:f(0) = - 2.0 + 8[/tex]
simplify multiplication:
[tex] \sf f(0) = 8[/tex]
when x is 3
[tex] \sf f(3) = - 2.3 + 8[/tex]

Answer:
when x =0
f(x)=-2×0+8=8
when x =3
f(x)=-2×3+8=2
when x =6
f(x)=-2×6+8=-4
when x =9
f(x)=-2×9+8=-10

Write the log equation as an exponential equation. You do not need to solve for x.
log (x^2– 5x + 14) = 2x + 4
9514 1404 393
Answer:
x^2 -5x +14 = 10^(2x +4)
Step-by-step explanation:
The relationship is ...
log(a) = b ⇔ a = 10^b
__
Using this with a=x^2-5x+14 and b=2x+4, we have ...
x^2 -5x +14 = 10^(2x +4)

Additional comments
In plain text, the exponent needs parentheses, because superscript formatting is not available to tell what is and isn't part of the exponent.
The base of "log" is assumed to be 10 in high school algebra. In the larger world, "log" is often used in place of "ln" to mean the logarithm to base 'e'.

consider f(x)= square root of x^2-1 and g(x) = square root of x^2+1. what values of x would make f(g(x)) and g(f(x)) cumulative
Cumulative probability is a random variable determined by adding the probability density functions altogether, and its calculation can be defined as follows:
Cumulative function calculation:Random variable distributions are described using the cumulative distribution function. It can be applied to a discrete, continuous, or mixed variable to describe the probability.Given:
[tex]\to f(x)= \sqrt{x^2-1} \\\\\to g(x) = \sqrt{x^2+1}[/tex]
Find:
[tex]\to f(g(x))[/tex] and [tex]g(f(x))[/tex]
[tex]\to f(g(x))[/tex]
[tex]\to f(\sqrt{x^2+1})\\\\\to \sqrt{\sqrt{(x^2-1)+1}} \\\\\to \sqrt{\sqrt{x^2-1+1}} \\\\\to \sqrt{\sqrt{x^2}} \\\\\to \sqrt{x}} \\\\[/tex]
[tex]\to g(f(x))\\\\\to g(\sqrt{x^2-1})\\\\\to \sqrt{\sqrt{(x^2+1)-1}} \\\\\to \sqrt{\sqrt{x^2+1-1}} \\\\\to \sqrt{\sqrt{x^2}} \\\\\to \sqrt{x} \\\\[/tex]

the measures of the three angles of a triangle is 180
in a triangle, the measures of the three angles are x, x + 18, and x - 6. what is the measure of each angle
Answer:
X + X +18 + X-6 = 180
3x + 12 = 180
3x = 168
x= 56
x + 18 = 74
x - 6 =50
Step-by-step explanation:
Answer:
56°, 74°, 50°
Step-by-step explanation:
x + x + 18 + x - 6 = 180
3x + 12 = 180
3x = 168
x = 56
56 + 18 = 74
56 - 6 = 50
