Answer:

Explanation:

ok so there so many ways i can tell explian

1. The slope-intercept form of a line is: y=mx+b where m is the slope and b is the y-intercept. The y-intercept is always where the line intersects the y-axis, and will always appear as (0,b) in coordinate form.

2. how to find the Y-intercept when given two points

Steps

a. Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11)

b, Substitute the slope(m) in the slope-intercept form of the equation.

c, Substitute either point into the equation. You can use either (3,5) or(6,11).

d,Solve for b, which is the y-intercept of the line.

e, Substitute b, into the equation.

3. how to find the Y intercept in a quadratic equation

To find the y-intercept let x = 0 and solve for y. Step 3: Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form)

philly and boston were working on a project in carpentry class. they needed to cut 5 lengths of 234 feet from a board. how long

ss7ja [257]

or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

Let x represent the total length of the board so as to allow for the cutting of 5 lengths.

Since each length needed to be cut is 234 feet, hence:

x = number of lengths × feet per board

x = 5 lengths × 234 feet

x = 1170 feet

Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

Which represents the solution set to the inequality ? x –1 x x is greater than or equal to StartFraction 7 Over 16 EndFraction.

Vikentia [17]

Inequalities are used to represent unequal expressions.

The solution set to $\mathbf{x \ge \frac{7}{16}}$ is: $[\mathbf{\frac{7}{16}, \infty)}$

The inequality is given as:

$\mathbf{x \ge \frac{7}{16}}$

From the inequality above, we have the following observation.

The value of variable x starts from 7/16 (inclusive)
The value of variable x has no end (i.e. infinity)

Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [

We treat $\infty$ , as an exclusive value. So, we make use of the close parenthesis i.e. )

Hence, the solution set is: $[\mathbf{\frac{7}{16}, \infty)}$
