Step-by-step explanation:

Substitution means to substitute a variable with the other variable in the equation.

Like, in this equation, y = -5x.

Substituting it in the equation y = 2x - 14, we get,

=> -5x = 2x - 14

=> -7x = -14

=> 7x = 14

=> x = 2

Now, putting value of x in y = -5x, we get,

y = -5 (2) = -10

Hope it helps.

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

horrorfan [7]

Answer:

Step-by-step explanation:

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

Find the minimum point for the function f(x) = |2x - 1| (0, ½) (½, 0) (0, -½) (-½, 0)

torisob [31]

Minimum point of an absolute value function is when f(x) = 0
0 = |2x - 1|
2x - 1 = 0
2x = 1
x = 1/2

Minimum point is (1/2, 0)

lawyer [7]

Answer: 3/8, 0.375, 37.5%

Step-by-step explanation:

Count the number of cards with odd numbers that are greater than 4. 5, 7, and 9 are odd numbers greater than 4. There are 3 cards with odd numbers greater than 4. Probability is found by dividing this by the total number of cards, 8. This gets you a fraction of 3/8.

Answer:

see below

Step-by-step explanation:

The y-coordinates of the points are the same, so the distance between those points will be the difference of the x-coordinates. The first number line shows those x-coordinates plotted properly. It can be used to find the difference between them.
