Answer 1

Answer:

The correct choice is option a. -3x^2 + xy + 3x - y + 2

Step-by-step explanation:

(xy + 3x + 2) - (3x^2 + y)

= xy + 3x + 2 - (3x^2 + y)

= xy + 3x + 2 - 3x^2 - y

= -3x^2 + xy + 3x - y + 2

Answer 2

The correct answer of the given choices i think it would be A

What is the equation of the line that is perpendicular to -2/5x-7 and passes through (4,-1)?

Answers

Step-by-step explanation:

maybe this is not the full expression, as you wrote the line equation in a funny way.

I understand the following :

the line is

y = (-2/5)×x - 7

perpendicular means crossing at a right angle (90 degrees).

the slope of the original line is -2/5.

as in every line equation, the slope is the factor of x. and it expresses the ratio y/x indicating the amount of units y is changing, when x changes a certain amount of units (e.g. when going from one point on the line to another).

the perpendicular slope turns the original y/x ratio upside-down, and also flips the sign.

so, it is 5/2.

the equation for the perpendicular line looks like

y = (5/2)×x + b

now what is b ?

for this we use the specified point on the line : (4, -1)

and we put these values as x and y into the equation :

-1 = (5/2)×4 + b = 5×2 + b = 10 + b

b = -11

and so, the full equation of the perpendicular line is

y = (5/2)×x - 11

Which lists all of the y-intercepts of the continuous function in the table?

(0, 0)

(–1, 0), (2, 0)

(–1, 0), (0, 0)

(–1, 0), (0, 0), (2, 0)

Answers

Answer:

A (0,0)

Step-by-step explanation:

When a function intersects the y-axis then the point of intersection is called y-intercept of the function,

Also, for y-intercept x = 0.

That is, if f(x) is the function then its y-intercept is (0, f(0) )

By the given table for x = 0, f(x) = 0

Hence, the y-intercept of the given function is (0,0),

Option A is correct.

What is the volume of air in a lab of dimensions 8 mx 5 m x 3 m?

What is the mass of the air? (Density of air = 1.3 kg/m3)

Answers

Answer:

Volume of air = 120 m³

Mass of air = 156 kg

Step-by-step explanation:

Volume of air in a lab of dimensions,

= 8 x 5 x 3

Find the slope of the line passing through each of the following pairs of points and draw the graph of the line. (-2,3), (5, 5)
There isn't any graph example but I need help!!! i will award 10 brainiest

Answers

Answer:

Slope: 2/7

Step-by-step explanation:

y2 - y1/ x2 - x1 = 2/7

Given the points:

(x1, y1) = (-2, 3)
(x2, y2) = (5, 5)

Substitute these values into the slope formula:

m = (y2 - y1)/(x2 - x1)
m = (5 - 3)/(5 - (-2))
m = 2/(5 + 2) = 2/7

Therefore, the slope of the line is 2/7.

To graph a line, plot both of the given points and draw a line connecting those points.

Attached is the screenshot of the graph, using both points.

Step-by-step explanation:

The triangle’s angles add up to 180°

so 180 - (5x - 2) = the another one interior angle

180 - 5x + 2

182 - 5x

and then 2x + 76 + (182 - 5x) = 180

2x + 76 + 182 - 5x = 180

258 - 3x = 180

78 = 3x

x = 26

so 2x = (26)(2) = 52

5x - 2 = (5)(26) - 2 = 128

Answers

Answer:

(8, - 10) or (0, 6)

Step-by-step explanation:

There are two options as below.

1. JL/JK = 5 : 1

Find the coordinates of L:

x = -2 + 5/6(10 - (-2)) = -2 + 10 = 8y = 10 + 5/6(-14 - 10) = 10 - 20 = - 10

The point is L(8, - 10)

2. JL/JK = 1 : 5

Find the coordinates of L:

x = -2 + 1/6(10 - (-2)) = -2 + 2 = 0y = 10 + 1/6(-14 - 10) = 10 - 4 = 6

The point is L(0, 6)

Answers

Answer:

Remember that the slope is the change in y/the change in x

Step-by-step explanation:

1. The slope [tex]\frac{-0.5- 0.5}{3 - (-3)}[/tex]

= [tex]\frac{-1}{6}[/tex]

2. Find "b" which is the y-intercept. Pick one of the two point and the slope.

Let use (-3, 0.5) and the slope is -1/6

y = mx + b

0.5 = -1/6 (-3) + b Solve for b

3 = 3 + b Multiply each term by 6

0 = B

3. Write the equation of the line y = mx + b

y = -1/6x + 0
