Which is the graph of the linear inequality 2x – 3y < 12?

On a coordinate plane, a solid straight line has a positive slope and goes through (0, negative 4) and (3, negative 2). Everything to the right of the line is shaded.

On a coordinate plane, a dashed straight line has a positive slope and goes through (0, negative 4) and (3, negative 2). Everything to the right of the line is shaded.

Answer:

x = 1, y = 6

or

x = 5, y = 2.

Step-by-step explanation:

y=x2−7x+12

y=−x+7

Substitute for y in the first equation:

- x + 7 = x^2 - 7x + 12

x^2 - 7x + x + 12 - 7 = 0

x^2 - 6x + 5 = 0

(x - 1)(x - 5) = 0

x = 1, 5.

When x = 1, y = -1 + 7 = 6.

when x = 5, y = -5+7 = 2.

How do we write 8x-2y=10 in slope intercept form?

[tex]\blue\textsf{\textbf{\underline{\underline{Answer and Solution:-}}}}[/tex]

First subtract 8x on both sides:-

-2y=10-8x

or

-2y=-8x+10

Now divide by -2 on both sides:-

y=2x-5

This is our equation in slope intercept form.

Answer:

0.9219

Step-by-step explanation:

Starting at the deccimal point and going right, the places are: tenths (one decimal place), hundredths, thousandths, ten-thousandths. So that the number is ten-thousandths means it has four decimal places. Those digits are given in the problem "nine thousand two hundred nineteen"

Answer:

78º

Step-by-step explanation:

Note : -

In mathematics, the reference angle is defined as the acute angle and it is measuring less than 90 degrees. It is always the smallest angle, and it makes the terminal side of an angle with the

x - axis.

Step 1 : -

Find where 192º lies in which quadrant.

192º lies in 3rd quadrant ( between

180º and 270º )

Step 2 : -

Subtract : 270 - 192

270 - 192 = 78º

( Since, 192º is greater than 180º, is subtracted from 270º )

Answer : -

78º is the reference angle for 192º.

Answer:

Step-by-step explanation:

so to go forward we input x and get out y,   to go backwards ( the inverse) we plug in y and get out x   ,  so just solve the equation for x

f(x) = 8x - 5

remember that f(x) = y

so,

y = 8x - 5

now solve for x

y+5 = 8x

(y+5) / 8 = x

then remember that we want to swap x and y ,

(x+5) / 8 = y

now y = [tex]f^{-1}[/tex](x),  it's kinda confusing.

 [tex]f^{-1}[/tex](x)= [tex]\frac{x+5}{8}[/tex]

Answer:

[tex]\frac{10x^2+3}{y^2+4}[/tex]

Step-by-step explanation:

When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )

So we have [tex]\frac{6x^2+5}{y^2+4} +\frac{4x^2-2}{y^2+4} =\frac{(6x^2+5)+(4x^2-2)}{y^2+4}[/tex]

==> remove parenthesis and apply signs

[tex]\frac{x^2+5+4x^2-2}{y^2+4}[/tex]

==> simplify numerator by combining like terms

[tex]\frac{10x^2+3}{y^2+4}[/tex]

and we are done!

Note:

like terms are terms with the same variable and exponent

An example of like terms are 6x^7 and 3x^7 as they have x as a variable and a power of 7

The like terms being combined here were (6x² and 4x²) and (5 and -2)

Answer:

make the common denominator

[tex]\frac{6x^{2} +5+4x-2}{y^{2}+4 }[/tex]

combone the like terms

[tex]\frac{10x^{2} +5-2}{y^{2}+4 }[/tex]

subtract numbers

Step-by-step explanation:

If r is 1/6 then we'll have 1/4*1/6+7/24.

Firstly we will multiply 1/4 and 1/6 which will give us 1/24.

Then we will add 1/24 and 7/24 which will give us 8/24.

Then we reduce it to it's lowest term that is 1/3.TRY THIS.

9x10^100= 9e+100 3x10^40= 3e+40

Step-by-step explanation:

100-40 = 60

The value of x, when two angles are complementary with one angle value is x plus 9 degrees and the second angle value is 44 degrees, is 37 degrees.

The two angles are called complementary angles, when the sum of these two angle is equal to the 90 degrees.

Suppose there are two angle, angle A and angle B. These two angles will be complementary if,

[tex]m\angle A+m\angle B=90^o[/tex]

The figure shows complementary angles.

As, both the angles are complementary. Thus,

[tex](x+9)+44=90\\x+9+44=90\\x+53=90\\x=90-53\\x=37^o[/tex]

Thus, the value of x, when two angles are complementary with one angle value is x plus 9 degrees and the second angle value is 44 degrees, is 37 degrees.

Answer:

11

Step-by-step explanation:

area = (side a + side b)/2 times height

side a = (2 times (area ÷ height)) - side b

side a = (2 times (54+6)) - 7

side a = (2 times (9)) - 7

side a = 18 - 7

side a = 11

to get the hypotenuse of the triangle

11 - 7 = 4

base of the triangle is 2 (2 on either side)

pythagorean theorem

a squared + b squared = c squared

4 + 36 = 40

to get c or the hypotenuse

take the square root of 40

As m is a constant that is applied to x, it has to have something to do with minutes, eliminating A and B. As the constant is 2, it has to have something to with 2, eliminating D, meaning your answer is C. This is because a slope is the rate of change of y in relation to x, so it would be rate of change of y is a (a being your constant, in this case 2) per x. With your case, y is cost and x is minutes, leading to answer choice C.
