Answer:

Step-by-step explanation:

Hello!

We have to follow the order of PEMDAS

Parenthesis, Exponents, Multiplication and Division, Addition and Subtraction

5 x 5 - (6 - 1) + $6^{2}$

Parenthesis First

$5 x 5 - (5) + 6^2$

Exponents next

$5x5 - (5) + 36$

Multiplication and Divsion from left to right

25 - (5) + 36

Addition and Subtraction from left to right

20 + 36

The answer is 56

Hope this Helps!

Answer:

Step-by-step explanation:

Keep the order of opperations in mind when doing this (PEMDAS). First, solve what is inside the parentheses (6-1). Then, solve the exponent and the multiplication (6² and 5×5). Finally, finish adding and subtracting to get the answer.

What is the equation in slope intercept form of the perpendicular bisector of the given line segment?

andreev551 [17]

Answer:

y = -4x - 6

Step-by-step explanation:

The equation of a line in point-slope form.

$y - y_1 = m(x - x_1)$

is the equation of the line containing point (x1, y1) and having slope, m.

The given point of the perpendicular bisector is (-1, -2), so in this case, x1 = -1, and y1 = -2.

We need the slope of the perpendicular bisector. First we find the slope of the segment. We start at point (-5, -3). We go up 1 unit and 4 units to the right, and we are at another point on the segment. Since slope = rise/run, the slope of the segment is 1/4. The slopes of perpendicular lines are negative reciprocals, so the slope of the perpendicular bisector is the negative reciprocal of 1/4, so for the perpendicular bisector, m = -4.

Now we use the equation above and our values.

$y - y_1 = m(x - x_1)$

$y - (-2) = -4(x - (-1))$

$y + 2 = -4(x + 1)$

$y + 2 = -4x - 4$

$y = -4x - 6$

Answer:

The slope is 3

The y-intercept is -2

The linear equation is y = 3x - 2

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

m is the slope of the line

b is the y-intercept

The rule of the slope of a line that passes through points (x1, y1) and (x2, y2) is m = $\frac{y2-y1}{x2-x1}$

∵ A line passes through points (2, 4) and (6, 16)

∴ x1 = 2 and y1 = 4

∴ x2 = 6 and y2 = 16

→ Substitute them in the rule of the slope above to find it

∵ m = $\frac{16-4}{6-2}$ = $\frac{12}{4}$ = 3

∴ m = 3

→ Substitute it in the form of the equation above

∴ y = 3x + b

→ To find b substitute x and y in the equation by the coordinates of

a point on the line

∵ Point (2, 4) is on the line

∴ x = 2 and y = 4

∵ 4 = 3(2) + b

∴ 4 = 6 + b

→ Subtract 6 from both sides to find b

∵ 4 - 6 = 6 - 6 + b

∴ -2 = b

→ Substitute its value on the equation above

∵ y = 3x + (-2)

∴ y = 3x - 2

→ Let us answer the questions

The slope is 3

The y-intercept is -2

The linear equation is y = 3x - 2
