Simplify the expression 9x-4-12x-3

Answer:

1

Step-by-step explanation:

We have to convert the whole number into an improper fraction :

4  = 4/1

Now we multiply the numerators together and the denominators together :

4 × 1 = 4

1 × 4 = 4

Our new fraction is 4/4 = 1

Hope this helped and have a good day

We came to the conclusion that ΔQRT ≅ ΔSRT is under the side-side-side (SSS) condition.

So,

Given: ΔQRS/SRT is isosceles with QR ≅ SR; RT bisects QS at point T.

To prove: ΔQRT ≅ ΔSRT

So, we can say that ΔQRT ≅ ΔSRT under SSS condition.

Therefore, ΔQRT ≅ ΔSRT is congruent under SSS condition.

The equation of the line in point-slope form, which passes through the pair of points located at (-10 , 3) and (-2 , -5), is y - 3 = -(x + 10).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Getting the slope of the two points: (-10 , 3) and (-2 , -5).

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

m = (-5 - 3)/(-2 - -10)

m = -8/8

m = -1

Using the point slope form, plug in the values of the slope and one point to set up the equation.

(y - y1) = m(x - x1)

where m = -1 and (x1 , y1) =  (-10 , 3)

(y - 3) = -1(x - -10)

y - 3 = -(x + 10)

4n = 16 ( divide both sides by 4 )

n = 4

then the number n is 4

Using algebra, The product of two consecutive numbers is 18 more then 8 times a number

Roughly speaking, algebra is the study of mathematical symbols and the rules for manipulating these symbols in formulas; it is a unifying thread of almost all of mathematics

The two consecutive numbers are :

x and x+1

x(x+1) = 8(x+1) + 18

x^2 + x = 8x + 8 + 18

x^2 + x = 8x + 26

x^2 + x - 8x - 26 = 0

x^2 - 7x - 26 = 0

Substitute a=1,b=−7 and c=−26 into the quadratic formula

       - B  ±  √ B2-4AC

 x =   ————————

                     2A

Accordingly,  B^2  -  4AC   = 49 - (-104) =    153

Applying the quadratic formula :

             7 ± √ 153

  x  =    —————

                  2

x  =  ( 7 ± 3 ×  4.123 ) / 2

​

Two real solutions:

x =(7+√153)/2=(7+3√ 17 )/2= 9.685

Solving for the rate, you make $15 per hour as a tutor.

Rate is defined as the ratio between two quantities of different units.

Let x = rate

n = total amount you've earned = $195.00

t = time you've worked = 8 hours

If in one week, you earned $75.00 at your afterschool tutoring job, and after working 8 more hours the following week, you had a total of $195.00, then we can express this as

n = xt + $75.00

Substitute the values to solve the rate, x.

n = xt + $75.00

$195.00 = x(8 hours) + $75.00

8hours (x) = $195.00 - $75.00

8hours (x) = $120.00

The solution of the given system of equations is (20/17, 19/17)

We can solve a system of equations using:

- graphical method

- elimination method

- substitution method

The given system of equations:

2x - 3y = -1  ...... (1)

3x + 4y = 8  ...... (2)

To be able to use the elimination method, multiply equation (1) by 3 and equation (2) by 2.

    2x - 3y = -1   (⨉3)

⇔ 6x - 9y =  -3   .........(3)

   3x + 4y = 8  (⨉2)

⇔ 6x + 8y = 16   .........(4)

Substract equation (3) from (4)

6x + 8y = 16

6x - 9y  =  -3   –

      17y = 19

          y = 19/17

Substitute  y = 19/17 into equation (1)

2x - 3y = -1

2x - 3(19/17) = -1

2x - 57/17 = -17/17

2x = (-17 + 57) / 17

2x = 40/17

x = 20/17

In mathematics, the logarithm is the reciprocal of a power. This means that the logarithm of a given number x is the exponent by which another fixed number (the base b) must be increased to get that number x. The simplest logarithm counts the number of times the same element occurs when multiplying repeatedly. The logarithm of x to base b is denoted by log b (x), or log b x without parentheses. Also, if confusion is impossible or the base doesn't matter, log x shows that even without an explicit base: B. In big O notation.

If 37 kids stayed home, the daycare normally has 143 kids.

We can use algebra to solve the problem.

Let's call the total number of kids in the daycare "x".

We know that 74% of the kids were absent, which means that 26% (100% - 74%) of the kids came to the daycare.

Note:  37 kids stayed home.

Set up the following equation:

0.26x = 37

To solve for x,  divide both sides by 0.26:

x = 37 / 0.26

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of hours in a single shift be = A

Now , The total length of equal shifts Skylar worked last week = 3 3/4 shifts

The total length of equal shifts Skylar worked last week = 15 / 4 shifts

The total number of hours Skylar worked in the week = 11 1/4 hours

The total number of hours Skylar worked in the week = 45 / 4

Now , the equation will be

Total length of equal shifts Skylar worked last week = total number of hours Skylar worked in the week

So ,

Total length of one shift of Skylar = total number of hours Skylar worked in the week / Total length of equal shifts Skylar worked last week

On substituting the values in the equation , we get

Total length of one shift of Skylar A = ( 45/4 ) / ( 15/4 )

On simplifying the equation , we get

A = ( 45/4 ) / ( 15/4 )

A = 45 / 15

A = 3 hours

Therefore , the value of A is 3 hours

Hence , The total number of hours in a single shift is 3 hours

CN and DN are radii of the same circle. So, they are equal in length then the value of DN = 8 cm.

A circle is defined as the collection of all points in the plane that are a fixed distance (the radius) from a fixed point (the center). A radius is any interval that connects a point on a circle to its center. Any two radii have the same length according to the definition of a circle.

A circle is a two-dimensional closed figure in which the set of all points in the plane is equidistant from a given point known as the "center."

A circle is a shape formed by all points in a plane that are at a given distance from the center. It is the curve traced out by a point moving in a plane so that its distance from a given point remains constant.

The equation of line parallel to the given equation and goes through the given point is y = 7x - 26.

Given the data in the question;

First, we determine the slope by comparing the equation with the slope intercept formula ( y = mx + b )

y = 7x + 3

Hence,

Slope m = 7

Next, we use the point-slope formula y-y₁ = m( x-x₁ ) to determine the equation of the line parallel.

Note that, the slopes must equal.

Given that; slope m = 7, Point: (-4,-2)

Plug into the point-slope formula and simplify.

y-y₁ = m( x-x₁ )

y - (-2) = 7( x - (-4) )

y + 2 = 7( x + 4 )

y + 2 = 7x + 28

y = 7x + 28 - 2

y = 7x - 26

Therefore, the equation of line parallel to the given equation and goes through the given point is y = 7x - 26.
