Answer:

d. Keisha did not make a mistake

Step-by-step explanation:

3+(-4)-7

3+(-4)+(-7) adding negatives is the same as subtracting

3+(-11) -4 and -7 do make -11

-8 3 and -11 do make -8

So she did it correctly, which means d is the right answer.

:) ur welcome

Answer:

sorry no answer

I apologize

Answer:

No

Step-by-step explanation:

Given 3 angles, the shape is a triangle.

The sum of all angles in a triangle = 180°

60° + 62° + 60° = 182°

Since it doesn't equal to 180°, it can't form a polygon

Answer:

8.1

Step-by-step explanation:

8.1 is the highest as you would look at the first number before the decimal and is the highest in this equation.

Answer:

the answer is 8.1 to 8 1/2 to 8 7/8

Answer:

No, because the longest side is too short to be the hypotenuse of a right triangle.

Step-by-step explanation:

To see if the sides form a right triangle

6² + 8² = 9²

36 + 64 = 81

100 ≠ 81

The the 3rd side is too short

Answer:

63a + 6

Step-by-step explanation:

we have to first simplify this

(3a+6)(7a-2)

21a-6+42a+12

63a+6

Answer:

Step-by-step explanation:

Use FOIL method

(3a+ 6)(7a - 2) = 3a* 7a + (3a)*(-2) + 6*7a + 6*(-2)

                       = 21a² - 6a + 42a - 12   {Combine like terms}

                       = 21a² + 36a - 12

Answer:

y = 13/4x - 21

Step-by-step explanation:

y2 - y1 / x2 - x1

5 - (-8) / 8 - 4

13/4

y = 13/4x + b

5 = 13/4(8) + b

5 = 26 + b

-21 = b

Answer:

(x - 9)(x + 2)

Step-by-step explanation:

x² - 7x - 18

x² + 2x - 9x - 18

x(x + 2) - 9(x + 2)

(x - 9)(x + 2)

Answer:

-1

Step-by-step explanation:

To find the slope given two points

m = ( y2-y1)/(x2-x1)

    = ( 8 - 2)/( -3 -3)

    = 6 / -6

    = -1

Answer:

inequality: x > -3

Set notation: {x: x> -3}

Interval notation: [-3, ∞)

The interval can be described as inequality is x>-3, the set notation is {x: x>-3}, and the interval notation is [-3, α).

The positive, negative, whole, and rational numbers can be mark on a number line. Numbers appearing on the right side of 0 are positive, and those reflected on the left side are negative.

The thick line on the picture starts at -3 and tends towards positive infinity.  So, it can be represented as inequality by x>-3.

The set notation can be described for x-axis elements since it is a line. The elements greater than -3 are present in it. So it can represented as {x :x> -3}.

The interval ranges from -3 to positive infinity; hence, it can be represented as [-3,α).

So we can conclude that the interval can be represented by an inequality as x > -3, the set notation contains elements greater than -3, and the interval ranges from -3 to positive infinity.

Answer:

-1 * (x/y)

Step-by-step explanation:

-x/y = x /-y

Factor out the negative

-(x/y) = -(x/y)

This is equal to -1 * (x/y)

given,

f(x) = 1

Now,

f(x) = 4x+11

or, -1 =4x +11

or,4x = 11+1

or, 4x = 12

or, x. =12/4

or x. = 3

Therefore, The value of x is 3.

Answer:

[tex]16[/tex]

Step-by-step explanation:

The discriminant of a quadratic in standard form [tex]ax^2+bx+c[/tex] is given by [tex]b^2-4ac[/tex].

The quadratic [tex]-3=-x^2+2x[/tex] in standard form is [tex]-x^2+2x+3[/tex]. Thus, we can assign the following values:

Therefore, the discriminant of this quadratic is [tex]2^2-4(-1)(3)=4+12=\boxed{16}[/tex]

Step-by-step explanation:

Answer:

[tex] \rm \displaystyle \theta = \{ {150}^{ \circ} , {240}^{ \circ} \}[/tex]

Step-by-step explanation:

we would like to solve the following equation:

[tex] \displaystyle 2 \sin( \theta) \tan( \theta) = - 3[/tex]

to do so we need to put the equation in term of a function of a angle therefore rewrite tanθ:

[tex] \displaystyle 2 \sin( \theta) \cdot \frac{ \sin( \theta) }{ \cos( \theta) } = - 3[/tex]

simplify multiplication:

[tex] \displaystyle \frac{ 2\sin^{2} ( \theta) }{ \cos( \theta) } = - 3[/tex]

cross multiplication:

[tex] \displaystyle 2\sin^{2} ( \theta) = - 3 \cos( \theta) [/tex]

isolate -3cosθ to left hand side and change its sign:

[tex] \displaystyle 2\sin^{2} ( \theta) + 3 \cos( \theta) = 0[/tex]

well we can rewrite sin²θ by applying Pythagorean theorem and that yields:

[tex] \rm \displaystyle 2(1 - \cos^{2} ( \theta)) + 3 \cos( \theta) = 0[/tex]

distribute:

[tex] \rm \displaystyle 2 - 2\cos^{2} ( \theta) + 3 \cos( \theta) = 0[/tex]

now notice that our equation ended up with a pattern and that is Quadratic thus by letting cosθ be x to transform the equation:

[tex] \rm \displaystyle 2 - 2 {x}^{2} + 3 x = 0[/tex]

rearrange it to standard form:

[tex] \rm \displaystyle - 2 {x}^{2} + 3 x + 2 = 0[/tex]

divide both sides by -1:

[tex] \rm \displaystyle 2 {x}^{2} - 3 x - 2 = 0[/tex]

well we can factor the quadratic to do so rewrite -3x as -4x+x:

[tex] \rm \displaystyle 2 {x}^{2} - 4 x + x - 2 = 0[/tex]

factor out 2x:

[tex] \rm \displaystyle 2x ({x}^{} - 2)+ x - 2 = 0[/tex]

factor out 1:

[tex] \rm \displaystyle 2x ({x}^{} - 2)+ 1(x - 2 ) = 0[/tex]

group:

[tex] \rm \displaystyle (2x + 1)(x - 2 ) = 0[/tex]

by Zero Product property we obtain:

[tex] \rm \displaystyle \begin{cases} 2x + 1 = 0\\ x - 2 = 0 \end{cases}[/tex]

cancel 1 from the first equation and add 2 to the e equation:

[tex] \rm \displaystyle \begin{cases} 2x = - 1\\ x = 2\end{cases}[/tex]

substitute back:

[tex] \rm \displaystyle \begin{cases} 2 \cos( \theta) = - 1\\ \cos( \theta) = 2\end{cases}[/tex]

since cosθ is only defined for the interval [1,-1] the second equation is false for any value of θ but we can still continue the first equation

[tex] \rm \displaystyle \begin{cases} 2 \cos( \theta) = - 1\\ \cos( \theta) \neq 2\end{cases}[/tex]

divide both sides by 2:

[tex] \rm \displaystyle \cos( \theta) = \frac{ - 1} {2}[/tex]

by unit circle we acquire:

[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} \\ \theta = {240}^{ \circ} \end{cases}[/tex]

add period of 2nπ:

[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} + 2n\pi\\ \theta = {240}^{ \circ} + 2n\pi \end{cases}[/tex]

for the interval [0,2π) θ is only defined when n is 0 Thus:

[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} + 2(0)\pi\\ \theta = {240}^{ \circ} + 2(0)\pi \end{cases}[/tex]

simplify:

[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} \\ \theta = {240}^{ \circ} \end{cases}[/tex]

hence,

θ is equal to 150° and 240°
