Answer:

y = 1/2x + 4

Step-by-step explanation:

If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.

So solve for b: using y = mx + b

2 = 1/2(-4) + b

2 = -2 + b

4 = b

Put it all together

y = 1/2x + 4

28:x

28/8=3.5

therefore 6*3.5 = x

Answer:

The answer is 21

Step-by-step explanation:

If you do 28/8 you get 3.5. So he used 3 1/2 blueberries. Then you have to times 6 by 3.5 to get 21. Put it back into ratio form and you get 28:21

Answer: No, you cannot.

Step-by-step explanation: A square number cannot be a perfect number.

The numbers: 0, 1, 5, 14, 30, 55, 91, 140, 204, 285, 385, 506, 650, 819, 1015, 1240, 1496, 1785, 2109, 2470, 2870, 3311, 3795, 4324, 4900, 5525, 6201 are examples of perfect numbers.

Given:

The figure of a right triangle ABC.

To find:

The trigonometric ratios [tex]\sin B, \tan A, \cos B[/tex].

Solution:

Using Pythagoras theorem,

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]AB^2=AC^2+BC^2[/tex]

[tex](10)^2=(6)^2+BC^2[/tex]

[tex]100-36=BC^2[/tex]

[tex]64=BC^2[/tex]

Taking square root on both sides.

[tex]\sqrt{64}=BC[/tex]

[tex]8=BC[/tex]

So, measure of BC is 8 units.

Now,

[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]

[tex]\sin B=\dfrac{AC}{AB}[/tex]

[tex]\sin B=\dfrac{6}{10}[/tex]

[tex]\sin B=\dfrac{3}{5}[/tex]

Similarly,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

[tex]\tan A=\dfrac{AC}{BC}[/tex]

[tex]\tan A=\dfrac{6}{8}[/tex]

[tex]\tan A=\dfrac{3}{4}[/tex]

And,

[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos B=\dfrac{BC}{AB}[/tex]

[tex]\cos B=\dfrac{8}{10}[/tex]

[tex]\cos B=\dfrac{4}{5}[/tex]

Therefore, the required trigonometric ration are [tex]\sin B=\dfrac{3}{5}, \tan A=\dfrac{3}{4}, \cos B=\dfrac{4}{5}[/tex].

Answer:

Step-by-step explanation:

Remark

Since the chords of the circle are equal and non intersecting, The 2 bisecting perpendiculars are going to be equal.

Equation

5x = 7x - 8           Subtract 7x from both sides

5x - 7x = - 8

-2x = - 8              Divide by - 2

x = - 8/-2

x = 5

Answer:

x = 348

Step-by-step explanation:

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.

0.15x + 65 + 0.1x + 28 = 180

0.25x + 93 = 180

0.25x = 180 - 93

0.25x = 87

x = 87/0.25

x = 348

Answer: 1/3

Step-by-step explanation: slope is the difference between the y values over the difference of the x values

The slope of the line that passes through A(0,−5) and B(3,−4) will be 1/3.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope could be positive or negative.

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

Slope m = (-4 + 5)/(3 - 0)

m = 1/3

Hence "The slope of the line that passes through A(0,−5) and B(3,−4) will be 1/3".

Answer: f(-9)= 243

Step-by-step explanation:

f(x) = 4x²+7x -18

f(-9) = 4(-9)²+7(-9)-18

= 4(81) -63-18

= 324- 81

= 243

Since x ² + 8x + 7 = (x + 7) (x + 1), we have for x ≠ -7,

y = (x + 7) / (x ² + 8x + 7) = 1/(x + 1)

so y is undefined at x = -1, indicating a vertical asymptote, and there is a hole/removable discontinuity at x = -7. Then the answer is D.

Answer:

(a). 20 ; (b). $10.00 ;

Step-by-step explanation:

(a). 70 - 3x = 80 - 3.50x

- 3x + 3.50x = 80 - 70

0.5x = 10

x = 10 ÷ 0.5

x = 20 ( 30-day periods )

(b). $70.00 - $3.00(20) = $10.00

The number of days will be 20 days. Then the values of the gift cards will be equal and will be $10.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Tavon has a gift card for $80 that loses $3.50 for each 30-day period it is not used. He has another gift card for $70 that loses $3 for each 30 days period it is not used.

Let y be the amount left of gift cards after x days and x be the number of days. Then the equation will be

y = 80 - 3.5x          ...1

y = 70 - 3x             ...2

From equations 1 and 2, we have

80 - 3.5x = 70 - 3x

0.5x = 10

x = 10 / 0.5

x = 20 days

The values of the gift cards will be equal and will be

y = 80 - 3.5(20)

y = 80 - 70

y = $10

The values of the gift cards will be equal and will be $10.

Answer: $5

Step-by-step explanation:

Let the small candy be represented by x.

The medium candy was twice as expensive as the small candy. This will be: = 2×x = 2x

The large candy was $5 more than the medium candy. This will be: = 2x + 5

Since Jason spent a total of $30 on

candy, the cost of the small candy will be:

x + 2x + 2x + 5 = 30

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25/5

x= 5

The small candy cost $5
