Answer:

y = -1/2x + 5

It will take 10 weeks for the cat to lose 5 pounds.

Step-by-step explanation:

Find slope

Take 2 points (2,4) (6,2)

y2 - y1/x2 - x1
2 - 4/6 - 2

slope = -1/2

y-intercept

(0,5)

y = mx + b form

m represents slope

b represents y-intercept

y = -1/2x + 5

Find the number of weeks it will the cat to lose 5 pounds

Set y = to 0, to find when the cat loses weight

0 = -1/2x + 5

Subtract 5 in both sides

-5 = -1/2x

Isolate the variable by getting rid of the denominator

-1/2x * 2 = -x

2 * - 5 = -10

Simplify

-x = -10

Divide both sides by -1

-x/-1 = x

-10/-1 = 10

Simplify

x = 10

Answer:

y = -1/2 x +5

10 weeks

Step-by-step explanation:

The y intercept is 5 ( That is is the point where x=0)

Our slope is rise over run or 1 lb /2 weeks

We know this is negative because the cat is losing the weight

slope = -1/2

The equation in slope intercept form is

y= mx + b where m is the slope and b is the y intercept

y = -1/2 x +5

We need to determine when y=0 to find when the cat loses all 5 lbs

0 = -1/2 x +5

Subtract 5 from each side

0-5 = -1/2x +5-5

-5 = -1/2x

Multiply each side by -2 to get x alone

-5 *-2 = -1/2x * -2

10 = x

It will take 10 weeks

Jared buys 3 pounds of chicken at $3.15 per pound and 1 pound of broccoli at $1.40 per pound. How much will it cost to make dinn

zaharov [31]

Answer:

Cost of dinner: $10.85

Money to add: $1.40

Step-by-step explanation:

1. Calculate the cost of the chicken and broccoli: 3(3.15)+1(1.40)=$10.85

2. Subtract Jared's money from the cost of dinner: $10.85-$9.45=$1.40

NO LINKS!! Use the method of substitution to solve the system. (If there's no solution, enter no solution). Part 11z

Roman55 [17]

Answer:

$(x,y)=\left(\; \boxed{-1,-8} \; \right)\quad \textsf{(smaller $x$-value)}$

$(x,y)=\left(\; \boxed{5,16} \; \right)\quad \textsf{(larger $x$-value)}$

Step-by-step explanation:

Given system of equations:

$\begin{cases}y=x^2-9\\y=4x-4\end{cases}$

To solve by the method of substitution, substitute the first equation into the second equation and rearrange so that the equation equals zero:

$\begin{aligned}x^2-9&=4x-4\\x^2-4x-9&=-4\\x^2-4x-5&=0\end{aligned}$

Factor the quadratic:

$\begin{aligned}x^2-4x-5&=0\\x^2-5x+x-5&=0\\x(x-5)+1(x-5)&=0\\(x+1)(x-5)&=0\end{aligned}$

Apply the zero-product property and solve for x:

$\implies x+1=0 \implies x=-1$

$\implies x-5=0 \implies x=5$

Substitute the found values of x into the second equation and solve for y:

$\begin{aligned}x=-1 \implies y&=4(-1)-4\\y&=-4-4\\y&=-8\end{aligned}$

$\begin{aligned}x=5 \implies y&=4(5)-4\\y&=20-4\\y&=16\end{aligned}$

Therefore, the solutions are:

$(x,y)=\left(\; \boxed{-1,-8} \; \right)\quad \textsf{(smaller $x$-value)}$

$(x,y)=\left(\; \boxed{5,16} \; \right)\quad \textsf{(larger $x$-value)}$
