Is 3x + 4y = -1 parallel or perpendicular, or neither?

Answer:

702 & 388

Step-by-step explanation:

let no =x&y

x-y=314

x+y/2=545

cross

x+y=1090

y=x-314

x+x=1090+314

2x=1404

x=702

y=702-314

=388

Answer: below(=

Step-by-step explanation: Given that,

dimensions of wall = 8.3ft by 7.5ft

height of wall = 8.3

width of wall = 7.5

there are total 3 walls in a bedroom to be painted blue.

Formula to calculate area of one wall

Height x Width

Formula to calculate area of four walls

3 (Height x Width)

= 3( 8.3ft x 7.5ft)

= 3 (62.25 ft²)

= 186.75 ft²

So area Alyssa will paint = 186.75 ft²

I am not that sure but i think this is the answer

Answer:

Step-by-step explanation:

You are given a right triangle. The square in the  corner of the triangle tells you that that angle = 90°.  Also the sum of all three angles in a triangle = 180°.

Sum of the angles in the triangle = 40° + 90° + y = 180°

                                                              130° + y = 180°

                                                                       y = 180° - 130°  

                                                                       y = 50°

Second way:

The acute angles of a right triangle = 90°. Therefore  40° + y =  90°

                                                                                                 y = 90° - 40°

                                                                                                 y = 50°

Answer:

6x^3 - 16x^2 - 14x + 24

Step-by-step explanation:

(x - 1)(x - 3 ) = x^2 - 3x - x + 3

2 (3x + 4) = 6x + 8

(x^2 - 3x - x + 3) (6x + 8)

= 6x^3 + 8x^2 - 24x^2 - 32x + 18x + 24

= 6x^3 - 16x^2 - 14x + 24

The Unit price at Snacks & More is $5.75 per pound

Unit price is the price for a single unit of product.

Given that Snacks & More sells a 3-pound bag of mixed nuts for $17.25, hence:

Unit price at Snacks & More = $17.25 / 3 pound = $5.75 per pound

Healthy Snacking sells a 2.5-pound bag of mixed nuts for $13.75.

Unit price at Healthy Snacking = $13.75 / 3 pound = $4.58 per pound

The Unit price at Snacks & More is $5.75 per pound

Answer:

x = -7/2

Step-by-step explanation:

-2(5x - 3) = 41

Distribute the -2 inside the parenthesis.

-10x + 6 = 41

Subtract 6 from both sides.

-10x = 35

Divide both sides by -10.

x = 35/-10

Simplify the fraction.

x = -7/2.

Proof:

-2(5x - 3) = 41

Substitute variable.

-2(5(-7/2) - 3) = 41

Multiply 5 and -7/2.

-2(-35/2 - 3) = 41

Turn 3 into a fraction with denominator 2.

-2(-35/2 - 6/2) = 41

Subtract 6/2 from -35/2.

-2(-41/2) = 41

Multiply -2 and -41/2.

41 = 41.

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{3}{4}[/tex] x + 3 ← is in slope- intercept form

with slope m = - [tex]\frac{3}{4}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{3}{4} }[/tex] = [tex]\frac{4}{3}[/tex] , then

y = [tex]\frac{4}{3}[/tex] x + c ← is the partial equation

To find c substitute (3, 7 ) into the partial equation

7 = 4 + c ⇒ c = 7 - 4 = 3

y = [tex]\frac{4}{3}[/tex] x + 3 ← in slope- intercept form

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = [tex]\frac{4}{3}[/tex] and (a, b ) = (3, 7 ) , then

y - 7 = [tex]\frac{4}{3}[/tex] (x - 3) ← in point- slope form

If she charges clients a constant rate. Then the rate will be $20 per hour.

The rate is the ratio of the amount of something to the unit.

For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

Sabrina has been strolling canines to bring in cash. This week she procured a sum of $140 throughout the span of 7 hours.

Assuming she charges clients a constant rate. Then the rate is calculated as,

Rate = $140 / 7

Rate = $20 per hour

If she charges clients a constant rate. Then the rate will be $20 per hour.
