Step-by-step explanation:

Answer:

The equation

(x/2) = 44

The answer

x = 88

Answer:

Solve the inequality as though it were an equation. The real solutions to the equation become boundary points for the solution to the inequality. Make the boundary points solid circles if the original inequality includes equality; otherwise, make the boundary points open circles.

Answer:

lines are parallel

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines is - 1

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = 3, 1) and (x₂, y₂ ) = (8, 6)

m = [tex]\frac{6-1}{8-3}[/tex] = [tex]\frac{5}{5}[/tex] = 1 ← slope of line a

Repeat with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (2,9)

m = [tex]\frac{9-1}{2+6}[/tex] = [tex]\frac{8}{8}[/tex] = 1 ← slope of line b

Since both slopes are equal, line a and line b are parallel

Answer:

D. (1, 3)

Step-by-step explanation:

Based on the image uploaded, during the first march, move point A, 3 units left, the new position will (3, -4), then move point A again 5 units up, the new position will be (3,1).

From second march move point A  2 units left, the new position will be (1,1), finally move point A 2units up, the new position and last position will be (1, 3).

Thus, the drum major be standing on (1, 3)

Answer:

X= -1

Y= -3

Step-by-step explanation:

y=-5x-8

y=4x+1

-5x-8=4x+1

+5x. -1 +5x -1

-9=9x

-1=x

Y=4(-1)+1

-4+1

Y=-3

Don't be worried friend :)

-(y + 2) + 8 = 3

=> -(y + 2) = -5

=> y + 2 = 5

=> y = 3

Answer:

B: billie's solution is incorrect since she didnt  

subtract 36 from both sides

Step-by-step explanation:

on the second step, she added 36 on the right.

This is incorrect because when changing one

side on an equation you must change the side

in the same way.

Answer:

Answer:

C.

Step-by-step explanation:

Answer:

true

Step-by-step explanation:

Answer:

40.82cm

Step-by-step explanation:

half of 26 is 13

the second's circle diameter is 13

the formula for circumference is C = 2πr

where r is the radius and π is 3.14

diameter =2r

13 = 2r

r = 6.5

2 x 6.5 x 3.14 = 40.82

40.82 cm  

Answer:

true

Red

Answer:

Perimeter is all sides added together, while Area is one side height times length

Step-by-step explanation:

Since your shape is a square all sides are equal so the equation is the same for all sides

Perimeter = 4z+3+4z+3+4z+3+4z+3 or (4z+3)4

14z+12 <= answer for perimeter

Area = (4z+3) (4z+3)

16z^2+12z+12z+9

16z^2+24z+9 <= answer for area

Answer:

x = 3/2 - 5y/4

Step-by-step explanation:

5y + 4x = 6

-5y             -5y

4x = 6-5y

/4     /4 /4

x = 6/4 - 5y/4

x = 3/2 - 5y/4

Move all terms that don't contain  x  to the right side and solve.

Answer:

.2

Step-by-step explanation:

Step-by-step explanation:

that's explanation

The equation of a line passes through the point (10,1) and has a slope of

- 0.5 is y = - 0.5x + b.

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is its graph or rate of change is large.

Yes, A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx + b.

Now, A line is drawn on the coordinate plane that passes through the point (10, 1) and has a slope of - 0.5.

Therefore,  1 = - 0.5(10) + b.

1 = - 5 + b.

b = 6.

And hence equation of the required line is,

y = - 0.5x + 6.
