Answer:

1/3 + a = 5/4 = 4/15

Answer:

[tex]a = \frac{11}{12}[/tex]

Step-by-step explanation:

In order to find the value of a we just solve the equation as follows....

[tex]\frac{1}{3} + a = \frac{5}{4} \\[/tex]

[tex]a = \frac{5}{4} - \frac{1}{3}[/tex]

[tex]a = \frac{15}{12} - \frac{4}{12}[/tex]

[tex]a = \frac{11}{12}[/tex]

Answer:a=b/2-c/2

b=9+a

b=-2a

Answer:2x + 4

Step-by-step explanation:

if you divide two linear binomials, you will get a quotient that is a monomial with a remainder.  Use long division.

               2/3

            ___________

(3x - 7) |  2x + 4

              2x - (14/3)

             ___________

                    (14/3) + 4

Quotient is  2/3

Remainder =  (14/3) + (12/3) = 26/3

To check, we multiply the quotient by the divisor, then add the remainder to the result.

(2/3)(3x - 7) + (26/3) =

2x - (14/3) + (26/3) =

2x + (12/3) =

Answer:

Option 3

Step-by-step explanation:

The bisection of an angle is the division of that angle into two equal angles. The bisection of an angle is done by drawing a line (known as angle bisector) that splits the angle into two angles of equal measure.

Below shows how to bisect an angle:

Answer: 12663.3 cubic inches sand is needed for this sandbox.

Step-by-step explanation:

Formula : Volume of cuboid = Base area x height

Volume of sandbox = 1146 x  13  = 14898 cubic inches

Quantity of sand required to fill = 85% of Volume of sandbox

= 0.85  x  14898   [85% = 0.85 ]

= 12663.3 cubic inches

Hence,  12663.3 cubic inches sand is needed for this sandbox.

The derivative of [tex]y = 3x^4 - 2x^3 - 7x + 5[/tex] with respect to x is

dy/dx = 12x³ - 6x² - 7.

We have,

The power rule states that if we have a term of form a[tex]x^n[/tex], the derivative with respect to x is given by [tex]d/dx(ax^n) = nax^{n-1}.[/tex]

Applying the power rule, we differentiate each term as follows:

[tex]d/dx(3x^4) = 3 \times 4x^{4-1} = 12x^3\\d/dx(-2x^3) = -2 \times 3x^{3-1} = -6x^2\\d/dx(-7x) = -7 \times 1x^{1-1} = -7[/tex]

d/dx (5) = 0 (since 5 is a constant)

Combining these derivatives, we get:

dy/dx = 12x³ - 6x² - 7

Therefore,

The derivative of [tex]y = 3x^4 - 2x^3 - 7x + 5[/tex] with respect to x is

dy/dx = 12x³ - 6x² - 7.

Answer: slope = 4

Step-by-step explanation:

slope = m = rise/run = y1-y2/x1-x2

9-1/5-3 = 8/2 = 4

Answer:

15/4

Step-by-step explanation:

to find the slope with two coordinates use

y2 - y1 / x2 - x1

first find the difference between the ys

the 2nd y point is 5, and the 1st y point is -10, so subtract them from each other

5 - (-10) = 5 + 10 = 15

then find the difference between the xs

the 2nd x point is -1, and the 1st x point is -5, so subtract them from each other

-1 - (-5) = -1 + 5 = 4

now put the difference in ys over the difference in xs

15 / 4

So thats your slope
