Answer:

This is a function.

Step-by-step explanation:

The four given input values, {-6, -2, 1, 3}, are all unique, and each has a corresponding y-value. So there is no ambiguity regarding the output (function) values. Therefore, the relation shown represents a function.

Write the standard form equation of the line through the given points. through (0.-4) and (-3,-2)

Alexxx [7]

Answer:

The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is $\frac{2}{3}x+y=-4$

Step-by-step explanation:

The standard form of equation is $Ax+By=C$

Finding slope

Using the given points (0,-4) and (-3,-2) we can find slope using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

$Slope=\frac{-2-(-4)}{-3-(0)}\\Slope=\frac{-2+4}{-3} \\Slope=-\frac{2}{3}$

Finding y-intercept

Using point (0,4) and Slope=-2/3 we can find y-intercept

$y=mx+b\\-4=-\frac{2}{3}(0)+b\\-4=0+b\\b=-4$

The slope intercept form of the line through the given points. through (0.-4) and (-3,-2) having slope =-2/3 and b=-4 will be:

$y=mx+b\\y=-\frac{2}{3}x-4$

Now, standard form of equation will be: $\frac{2}{3}x+y=-4$

So, The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is $\frac{2}{3}x+y=-4$

Cedric bought his truck new for $20,000. It’s value decreases 15.4% each year. In approximately how many years will the value of

SVEN [57.7K]

Answer:

3.24 years

Step-by-step explanation:

We know that for the truck to become half of the value it has to decrease by %50 if it decreases by %15.4 the real question is 50/15.4=3.24 years because how many years will it take for %15.4 to pile up and eventually become %50

The sum of a certain quantity "P" together with its two-third, and it's half becomes 234

kykrilka [37]

You need to form an equation:
P+2/3P+1/2P=234
P+4/6P+3/6P=234
P+7/6P=234
13/6P=234
P=234/(13/6)
P=108

Equation 1: 5x + 3y = 19

poizon [28]

Answer:

Step-by-step explanation:

If you multiply the top equation by 2 and the bottom equation by -5, then there will be a 10x in the first equation and a -10x in the second, which you can cancel out in the next step. Therefore, the correct answer choice is C. Hope this helps!
