Alina has 15x + 12 yards of ribbon. She uses 6x - 3 yards for a project. How many yards does she have left?

Andrews [41]

Answer:

-1.66666666667 yards

Step-by-step explanation:

15x+12=6x-3

subtract 6x on both sides

9x+12=-3

subtract 12 on both sides

9x=-15

x=-1.6666666666667

Rewrite the function by completing the square<br><br> h(x)=4x^2+4x+1

lisov135 [29]

Answer:

$h(x) = 4(x+\frac{1}{2})^{2}$

Step-by-step explanation:

$h(x)=4x^2+4x+1\\h(x)=4(x^2+x+\frac{1}{4}) \\h(x)=4(x^2+x+\frac{1}{4})\\h(x) = 4(x+\frac{1}{2})^{2}$

Solve for y. 4y+5/3 = y-8/2 y = -4 y = -5 y = -8

horrorfan [7]

Answer:

Step-by-step explanation:

$\dfrac{4y+5}{3}=\dfrac{y-8}{2}\qquad\text{multiply both sides by }\ 2\cdot3=6\\\\6\!\!\!\!\diagup^2\cdot\dfrac{4y+5}{\not3_1}=6\!\!\!\!\diagup^3\cdot\dfrac{y-8}{\not2_1}\\\\2(4y+5)=3(y-8)\qquad\text{use distributive property}\\\\(2)(4y)+(2)(5)=(3)(y)+(3)(-8)\\\\8y+10=3y-24\qquad\text{subtract 10 from both sides}\\\\8y=3y-34\qquad\text{subtract 3y from both sides}\\\\5y=-34\qquad\text{divide both sides by 5}\\\\\boxed{y=-\dfrac{34}{5}}$

Is this ordered pair a solution to the inequality?<br> (1, 3)<br> 5x+y<-3<br> A.)No<br> B.)Yes

max2010maxim [7]

(1,3) means that x = 1 and y = 3. Let's make substitutions to see what happens with the inequality

5*x + y < -3
5*1 + y < -3 ... replace x with 1
5*1 + 3 < -3 ... replace y with 3
5 + 3 < -3
8 < -3

This is false. The number 8 is NOT smaller than -3.

So (1,3) is NOT a solution

Answer: Choice A) No
