Given: x = -2; y = -3; z = 5

It is clear that a numerical term can only be evaluated from an expression filled with numbers (no variables). In the expression provided, we have two variables, where y is being subtracted from x.

The expression can't be simplified because there is no like terms in the expression. However, since there are specific numerical values for each variable, we can substitute the numerical values for the variables in the expression and simplify the expression.

As planned, let's substitute the variables into the expression

Here, we know that x = -2 and y = -3.

If -2 is being subtracted by a negative integer, the negative integer will become positive, and the "minus sign" will be converted to a "plus sign".

We can conclude that 1 is the solution to the expression.

Employee's gross pay is their salary before any payroll deductions such as taxes, benefits, and other expenses are made.

Her goss weekly pay is $409.13.

Before taxes, benefits, and other payroll deductions are deducted, an employee's gross pay is what they are paid.

Net pay, often known as take-home pay, is the sum that is left over after all deductions have been taken into consideration.

Federal income tax:

306.36+ 43 = 349.36

Medical insurance:

349.36 + 22.35 = 371.71

Credit union:

371.71 + 25 = 396.71

State tax:

396.71 increased by 1.5% is 396.71 * (1.015) = 402.66

Local tax:

402.66 increased by 1.5% is 402.66 * (1.015)= 409.13

Her goss weekly pay is $409.13.

Step-by-step explanation:

Answer:x=1

Step-by-step explanation:

you would have to distribute the 5 into the (x+4)

then it would be

5x+20-3^2=2^4

then do the exponents

5x+20-9+16

then add 9 by both sides

5x+20=25

then subtract 20 on both sides

5x=5

then divide 5 on both sides

x=1

then check your work by putting 1 for x and you get 2^4=16

Answer:

Step-by-step explanation:

find x :

5( x + 4 ) - 3^2 = 2^4

5x + 20 - 9 = 16

5x = 16 - 20 + 9

5x = 5

x = 5 : 5

x = 1

----------------

check

5(1 + 4) - 3^2 = 2 ^4

25 - 9 = 16

16 = 16

A rock climber throws a first aid kit to the another climber who is higher up the mountain, the initial velocity of the kit is 12 m/s at an angle of 71 above the horizontal, at the instant when the kit is caught, it is traveling horizontally, so its vertical speed is zero, height difference between climbers is 0.85 m.

Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by specific unit of time (for example, 60 km/h northbound). In kinematics, area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.

Vertical motion of the first aid kit:

The Initial vertical velocity, u = 5.70 sin 45.7 = 4.08 m/s

Acceleration, g = -9.81 m/s²

When climber who is higher up the mountain catches the kit it's vertical speed is zero.

Final vertical velocity, v = 0 m/s

We have the equation of motion, v² = u² + 2as

Substituting

0² = 4.08² + 2 x -9.81 x s      

s = 0.85 m

So kit travels 0.85 m vertically.

Height difference between the climbers = 0.85 m.

Using the law of indices, [tex]1024^{\frac{2}{5} } = 16[/tex]

The expression can be solved using the law of indices as follows:

[tex]1024^{\frac{2}{5} }[/tex]

using law of indices, involving bracket.

Brackets with indices are where we have a term inside a bracket with an index (or power) outside of the bracket.

To do this we can raise everything inside the bracket to the power.

[tex](a^{b} )^{x} = a^{bx}[/tex]

Therefore,

1024 = 2¹⁰

Hence,

[tex]2^{\frac{2}{5} (10)} = 2^{\frac{20}{5} } = 2^{4} = 16[/tex]

Answer:

y=-5x+6

Step-by-step explanation:

the two lines are parallel so they have the same slope and if you put the like in y=mx+b it would be y=-5x+1 so the slope is -5

Then you need to put it into point slope for to figure it out y-y1=m(x-x1)

y-1=-5(x-1) (simplify)

y-1=-5x+5 (add 1 to both sides)

y=-5x+6

Answer:

x = 7.2 , y = 57 , z = 10.8

Step-by-step explanation:

the sum of the 3 angles in the outer triangle = 180° , that is

y + 88 + 35 = 180

y + 123 = 180 ( subtract 123 from both sides )

y = 57

------------

the outer and inner triangles are similar ( AA postulate ) then the ratios of corresponding sides are in proportion, that is

[tex]\frac{x}{12}[/tex] = [tex]\frac{9}{9+6}[/tex] = [tex]\frac{9}{15}[/tex] ( cross- multiply )

15x = 108 ( divide both sides by 15 )

x = 7.2

and

[tex]\frac{z}{18}[/tex] = [tex]\frac{9}{15}[/tex] ( cross- multiply )

15z = 162 ( divide both sides by 15 )

z = 10.8

Answer: yes then no

Step-by-step explanation:

Answer:

The measure of the largest angle is 145°

Step-by-step explanation:

Since the angles form a linear pair taking two angles that add to 180 and solving for x will give you the answer. the sentence "One angle is 5 more than four times the size of the other angle." your equation should look like this:

5 + 4x. the other angle uses the variable x. So the equation 5 + 4x + x = 180 should result in x = 35. That saying, the smaller angle is 35 and to find the larger angle either plug in x or subtract 180-35. both shoukd result in 145° which is the larger angle.

9/16 = 0.5625 (Terminating)

Explanation:

The definition of Terminate means to bring to an end. This would also apply to the decimals. To find whether a fraction is terminating or not, is to simply divide and you will get a decimal, unless it is mixed fraction. Terminating will bring an end, Ex: 1/2 ( 1 ÷ 2 ) which would equal = 0.5 This is an example of a terminating decimal. A repeating decimal is a decimal that never ends of its repetition, Ex: 0.13333333 (Continuous).

The sales in 2012 is estimated to be $40546.5 million if we use the midpoint formula assuming that the sales followed a linear pattern.

Midpoint is a term used in geometry and can be described as the center or middle point of a line segment. It enables you to take two endpoints, and then by using these endpoints you can find the point that is midway between them in the line segment.

Considering,

[tex]P_{1} = (x_{1},y_{1})[/tex]

[tex]P_{2} = (x_{2},y_{2})[/tex]

Here;

[tex]x_{1}[/tex] = 2010

[tex]x_{2}[/tex] = 2014

[tex]y_{1}[/tex] = $35,109 million

[tex]y_{2}[/tex] = $45,984 million

The formula for the midpoint is given as;

[tex]P_{m}[/tex] = {( [tex]x_{1} + x_{2}/2[/tex] ), ( [tex]y_{1} + y_{2} / 2[/tex] )}

[tex]P_{m}[/tex] = {(2010 + 2014 / 2), (35109 million + 45984 million / 2)}

[tex]P_{m}[/tex] = {(4024 / 2), (81,093 million / 2)}

[tex]P_{m}[/tex] = {2012 , 40546.5 million}

Therefore, the sales in 2012 are calculated to be $40546.5 million by using the midpoint formula.
