Which equation matches the graph y=-1x+3 , y=1x, y1x+3, y=-1x can you guys tell me which equation matches the graph with explanation

Answer: y = -1/2x -4

Step-by-step explanation:

Parallel lines have the same slope.

So first let’s find the slope of that given line.

x + 2y = 14

2y = -x+14

y = -1/2x + 7

The slope of our parallel line then will be -1/2.

Now let’s use the point they gave us to get “b” so we can finish the problem.

y= -1/2x + b

plug in (-8,0) so -8 for x and 0 for y

0 = -1/2(-8) + b

0 = 4 + b

b = -4

done!

An equation of the line that passes through the point (-8,0) and is

parallel to the line x + 2y = 14 is 2

The equation of a line in point slope form is expressed as:

Given the equation

x + 2y = 14

2y = -x + 14

y = -1/2x + 7

Slope of the line is -1/2

Substitute the point (-8, 0) and m = -1/2 into the formula

y - 0 = -1/2 (x+8)

2y = -x - 8

2y + x = -8

Hence an equation of the line that passes through the point (-8,0) and is

parallel to the line x + 2y = 14 is 2y+ x = -8

Answer:

Step-by-step explanation:

The decay is First order reaction

The half life of the first order reaction is given by

T(1/2)  = ㏑2/K

where K is the reaction constant for the first order reaction

T(1/2) = 2

2 = ln 2 /K

K = ln2/2

The equation of the first order reaction is given by

Kt = ln ([tex]\frac{Ro}{R}[/tex])

where

t = time = 10years

Ro = initial concentration

R = amount left after time t

upon substituting the values

[tex]\frac{ln2}{2}*10 = ln( \frac{500}{R})[/tex]

5ln2 = ln (500/R)

ln [tex]2^5[/tex] = ln (500/R)          (a*lnb = ln[tex]b^a[/tex])

[tex]2^5 = 500/R[/tex]

R = 500/32  = 15.625grams

Therefore the amount of pesticide left after 10 years is 15.625grams

The answer is x > 24.

Explanation:

Solving Inequality is almost the same as equation. However, you have to know one thing about solving an Inequality.

That is whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality.

[tex]-\frac{1}{2}x<-12[/tex]

Reminder that

[tex]-\frac{1}{2}x=-\frac{x}{2}[/tex]

We use negative x above 2 instead (Easier in solving)

[tex]-\frac{x}{2}<-12[/tex]

Then we move 2 to divide -12.

[tex]-x<-12(2)\\-x<-24[/tex]

Because the coefficient for x is in negative. We move -1 to divide -24 as we get 24 (Because negative divide negative = positive)

But remember that "whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality."

So we change from < to > instead.

Answer:

The bag costs 1500, while the umbrella cost 500

Step-by-step explanation:

Let the cost of the bag be b and the cost of the umbrella be u

Total cost is;

b + u = 2,000 •••••(i)

From the second part of the question;

b = 5u-1000 ••••••(ii)

Substitute ii into i

5u-1000 + u = 2000

6u = 2000 + 1000

6u = 3000

u = 3000/6

u = 500

To get b, substitute the value of u into equation ii

b = 5(500)-1000

b = 2500-1000

b = 1500

Thus,

[tex]\frac{\frac{2}{3}}{\frac{4}{-9}}=-\frac{3}{2}[/tex]
