What is the vertex of function f(x)=(x-3)(x+5)?

Answer:

See below.

Step-by-step explanation:

We know that

                              tanA + tan B

tan (A + B)     =     ---------------------                       

                               1 - tanAtanB

Substituting for A + B

tan (A + B) = tan pi/4 = 1.

            tanA + tan B

So        ------------------   =    1

             1 - tanAtanB

Therefore   tanA + tan B =   1 - tanAtanB.

Answer:

? = 58°

Step-by-step explanation:

Angles subtended by tangents and radii of a circle are supplementary, so

? + 122° = 180° ( subtract 122° from both sides )

? = 58°

Answer: A

Set up an equation:

3x - x = 28

Simplify:

2x = 28

Divide both sides by 2

X = 14

3(14) = 42

The numbers are 42 and 14

Answer: 40

Step-by-step explanation:

80 = 100%

40 = 50%

8 = 5%

5% x 4 = 20

8 x 4 = 32

32 = 20%

Answer:

-12, -12

Step-by-step explanation:

Both numbers are negative, they add to -24, 2 negatives make positive (-12 x -12 = 144)

Answer:

Parallel:

y=3x-7       y=-4x-1         y=1/3x +9     -9x+12y=24       y=x-3

y=3x+1       8x+2y=14     x-3y =3         y=3/4x -5          x-y=8

Perpendicular:

y=-2/5x +3       y=-1/4x        2x+7y=28      y=-5x+1        x+y=7     5x-10y=-20

y=2/5x +8        y=4x-5         7x-2y=4        x-5y=30         x-y=9     y=-2x+6

10x+8y=16

5y=4x-15

Neither:

3x+2y=8        4x+9=18        y=5/3x +7

2x+3y=-12      y=4x+9         6x-10y=10

The median is the number in the middle of a data set.

For example, in this question 7 is in the middle of the data set, thus making it the median.

Answer:

$34.40

Step-by-step explanation:

26.46 ×30% = 7.94

26.46+7.94= 34.4

The result is 85 divided by 2 equals 42.5.

So, when we divide 85 by 2, the quotient is 42, and there is a remainder of 1.

To divide 85 by 2, we need to perform the division operation step by step.

Divide the first digit of the dividend (85) by the divisor (2). The first digit of the dividend is 8.

8 ÷ 2 = 4

Write down the result (4) as the first digit of the quotient.

Multiply the divisor (2) by the quotient digit (4) and subtract the result from the first two digits of the dividend (85).

The result is the remainder.

85 - (2 * 4) = 85 - 8 = 77

Bring down the next digit of the dividend (7) to the remainder (77) to form a new dividend (77).

Divide the first digit of the new dividend (77) by the divisor (2).

77 ÷ 2 = 38 with a remainder of 1

Write down the quotient digit (38) as the second digit of the quotient.

Since there are no more digits to bring down, the division process is complete.

Now, we have the quotient and the remainder:

85 ÷ 2 = 42 with a remainder of 1

i.e. 85 ÷ 2 = 42.5

So, when we divide 85 by 2, the quotient is 42, and there is a remainder of 1.

Answer:

you'll have to subtract.

Step-by-step explanation:

9/4 -17/5

The rectangular form of the given equation r= 2 / 7sinθ−cosθ which is in polar form is  7x - y = 2 and the slope-intercept form is y = 7x - 2

To convert from polar form to rectangular form we simply take the following steps:

The slope-intercept form is,

y = mx +c

where m is the slope made and c is the intercept both made by the straight line.

In the given question let's first rearrange it,

r × (7sinθ − cosθ) = 2

Multiplying the term (7sinθ−cosθ) with r we get,

7rsinθ - rcosθ = 2

Now we will follow the steps discussed above which is we will put x and y respectively in place of rsinθ and rcosθ.

7x - y = 2

So, the slope-intercept form will be,

y = 7x - 2

Therefore, the rectangular form is 7x - y = 2 and the slope-intercept form is y = 7x - 2.

Answer:

Since MA ≠ TH, hence MATH is not a rectangle

Step-by-step explanation:

To prove that quadrilateral MATH, M (-4,-1) A(-3,2). T(3,0), H(2-3) is a rectangle, we need to get the length of each sides and show that MA =TH and MH = TA

For MA:

M (-4,-1) A(-3,2)

MA = √(2+1)²+(3+4)²

MA = √(3)²+(7)²

MA = √9+49

MA =√58

For TH:

T(3,0), H(2-3)

TH = √(-3-0)²+(2-3)²

TH = √(-3)²+(-1)²

TH = √9+1

TH =√10

For TH:

M(-4,-1), H(2-3)

MH = √(-3+1)²+(2+4)²

MH = √(-2)²+(6)²

MH = √4+36

MH =√40

For TA:

T(3,0), A(-3,2)

TA = √(2-0)²+(-3-3)²

TA = √(2)²+(-6)²

TA = √4+36

TA =√40

Since MA ≠ TH, hence MATH is not a rectangle
