Hi There!

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

Remember to follow PEMDAS.

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

Problem #1:

= (25 - 6.25) + (5 · 3)²

= (18.75) + (15)²

= 18.75 + 225

= 243.75

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

Problem #2:

= (8 + 3)² + 10 · (-4)

= (11²) + 10 · (-4)

= 121 + 10 · (-4)

= 121 + (-40)

= 81

Answer:

Yes, x + 12

Step-by-step explanation:

Simplify the following:

3 x - 2 x + 12

Grouping like terms, 3 x - 2 x + 12 = (3 x - 2 x) + 12:

(3 x - 2 x) + 12

3 x - 2 x = x:

Answer: x + 12

Answer:

Yes, it is.

Step-by-step explanation:

3x + 12 - 2x =

Use the commutative property of addition to change the order of the addition.

= 12 + 3x - 2x

Use the distributive property of addition over multiplication in reverse (which is factoring).

= 12 + x(3 - 2)

Do the operation: 3 - 2 = 1

= 12 + x * 1

Simplify x * 1 to just x.

= 12 + x

Use the commutative property of addition.

= x + 12

There you have x + 12 from 3x + 12 - 2x by using properties and operations.

Step-by-step explanation:

Answer:

the segment that states the radius is AC.

Step-by-step explanation:

To convert the slope-intercept form of a line, y = 6x - 4, to standard form, subtract 6x from both sides of the equation. The resulting standard form is -6x + y = -4.

You asked about writing the equation y = 6x - 4 in standard form. The standard form for the equation of a line in mathematics is usually given as Ax + By = C, where A, B, and C are constants, and A should ideally be a positive integer. To convert the given equation into standard form, we want to rearrange it so that both x and y are on the same side of the equation and the constant is on the other side.

Here are the steps to convert y = 6x - 4 to standard form:

Therefore, the standard form of the equation is -6x + y = -4.

Answer:

[tex]\frac{sin(3a)-cos(3a)}{sin(a)+cos(a)} =2sin(2a)-1[/tex]

Step-by-step explanation:

we are given

[tex]\frac{sin(3a)-cos(3a)}{sin(a)+cos(a)} =2sin(2a)-1[/tex]

we can simplify left side and make it equal to right side

we can use trig identity

[tex]sin(3a)=3sin(a)-4sin^3(a)[/tex]

[tex]cos(3a)=4cos^3(a)-3cos(a)[/tex]

now, we can plug values

[tex]\frac{(3sin(a)-4sin^3(a))-(4cos^3(a)-3cos(a))}{sin(a)+cos(a)} [/tex]

now, we can simplify

[tex]\frac{3sin(a)-4sin^3(a)-4cos^3(a)+3cos(a)}{sin(a)+cos(a)} [/tex]

[tex]\frac{3sin(a)+3cos(a)-4sin^3(a)-4cos^3(a)}{sin(a)+cos(a)} [/tex]

[tex]\frac{3(sin(a)+cos(a))-4(sin^3(a)+cos^3(a))}{sin(a)+cos(a)} [/tex]

now, we can factor it

[tex]\frac{3(sin(a)+cos(a))-4(sin(a)+cos(a))(sin^2(a)+cos^2(a)-sin(a)cos(a)}{sin(a)+cos(a)} [/tex]

[tex]\frac{(sin(a)+cos(a))[3-4(sin^2(a)+cos^2(a)-sin(a)cos(a)]}{sin(a)+cos(a)} [/tex]

we can use trig identity

[tex]sin^2(a)+cos^2(a)=1[/tex]

[tex]\frac{(sin(a)+cos(a))[3-4(1-sin(a)cos(a)]}{sin(a)+cos(a)} [/tex]

we can cancel terms

[tex]=3-4(1-sin(a)cos(a))[/tex]

now, we can simplify it further

[tex]=3-4+4sin(a)cos(a))[/tex]

[tex]=-1+4sin(a)cos(a))[/tex]

[tex]=4sin(a)cos(a)-1[/tex]

[tex]=2\times 2sin(a)cos(a)-1[/tex]

now, we can use trig identity

[tex]2sin(a)cos(a)=sin(2a)[/tex]

we can replace it

[tex]=2sin(2a)-1[/tex]

so,

[tex]\frac{sin(3a)-cos(3a)}{sin(a)+cos(a)} =2sin(2a)-1[/tex]

Answer:

To prove : sin(3a)-cos(3a)/sin(a)+cos(a) = 2sin(2a)-1                                      

Step-by-step explanation:

\frac{\sin3a-\cos3a}{\sin a+\cos a}=2\sin 2a-1\\\cos3a=4\cos^{3}a-3\cos a\\\sin 3a=3\sin a-4\sin ^{3}a\\substituting the value, we get\\L.H.S= \frac{3\sin a-4\sin ^{3}a-[4\cos ^{3}a-3\cos a]}{\sin a+\cos a}\\\frac{3(\sin a+\cos a)-4(\sin ^{3}a+4\cos ^{3}a)}{\sin a+\cos a}\\\frac{3(\sin a+\cos a)-4[(\cos a+\sin a)(\cos ^{2}a+\sin ^{2}a-\sin a\cos a)]}{\sin a+\cos a}\\\frac{3(\sin a+\cos a)-4[(\cos a+\sin a)(1-\sin a\cos a)]}{\sin a+\cos a}\\\frac{(\sin a+\cos a)[3-4(1-\sin a\cos a)]}{\sin a+\cos a}\\\frac{(\sin a+\cos a)[3-4+4\sin a\cos a]}{\sin a+\cos a}\\\frac{(\sin a+\cos a)(-1+4\sin a\cos a)}{\sin a+\cos a}\\-1+4\sin a\cos a\\-1+2\sin 2a\\2\sin 2a-1=R.H.S

Since, sin(2a)= 2sin(a)cos(a)

2sin(2a)= 4sin(a)cos(a)

Answer:

[tex]x_{1} = -1 - \sqrt{\frac{2}{3}}  ; x_{2} = -1 +\sqrt{\frac{2}{3}}[/tex]

Step-by-step explanation:

-6x -1 + 5x² = 8x²     Move all terms to the right-hand side

0 = 8x² - 5x² + 6x +1     Combine like terms

3x² + 6x + 1 = 0

Apply the quadratic formula

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

a = 3; b = 6; y = 1

[tex]x = \frac{-6\pm\sqrt{6^2 - 4\times 3 \times1}}{2\times 3}[/tex]

[tex]x = \frac{-6\pm\sqrt{36-12}}{6}[/tex]

[tex]x = \frac{-6\pm\sqrt{24}}{6}[/tex]

[tex]x = \frac{-6\pm \sqrt{4\times6}}{6}[/tex]

[tex]x = \frac{-6\pm 2\sqrt{2}}{6}[/tex]

[tex]x = -1 \pm \sqrt{\frac{2}{3}}[/tex]

[tex]x_{1} = -1 +\sqrt{\frac{{2}}{3}}; x_{2} = 1 -\sqrt{\frac{{2}}{3}}[/tex]

Answer:

x=9

Step-by-step explanation:

These two angles are equal because they are corresponding angles and the two lines are parallel.

13x-7 = 11x+11

Subtract 11x from each side

13x-11x -7 = 11x-11x+11

2x-7 = 11

Add 7 to each side

2x-7+7 = 11+7

2x = 18

Divide each side by 2

2x/2 = 18/2

x =9

Final answer:

Mr. Jimerson will earn $27.60 per hour after receiving a 15% raise on his original $24 per hour salary, resulting in a $3.60 increase per hour.

Explanation:

Mr. Jimerson earns $24 per hour working and qualifies for a 15% raise in salary. To calculate his new hourly salary after the raise, first determine the amount of the raise by finding 15% of his current hourly wage. Since 15% can be written as 0.15, we multiply his current wage by 0.15 to find the raise amount.

0.15 × $24 = $3.60

Next, add this raise amount to his original hourly wage to find his new salary:

$24 + $3.60 = $27.60 per hour

Therefore, Mr. Jimerson's salary after the raise will be $27.60 per hour.

Answer:

y = [tex]\frac{96}{5}[/tex]

Step-by-step explanation:

given that y and x are proportional then the equation relating them is

y = kx ← k is the constant of proportionality

to find k use the given condition y = 12 when x = 5

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{12}{5}[/tex]

y = [tex]\frac{12}{5}[/tex] x ← equation of proportionality

when x = 8, then

y = [tex]\frac{12}{5}[/tex] × 8 = [tex]\frac{96}{5}[/tex]

Answer:

0 solutions

Step-by-step explanation:

same slope, different y intercepts so they never intersect

Answer:

As both slopes are equal, and the values of b are different it means that the two lines are parallel and the system of equations does not have any solution. (Please see the picture below)

Step-by-step explanation:

1. First write the system of equations:

[tex]y=6x+2[/tex]

[tex]3y-18x=12[/tex]

2. Solve y for the second equation:

[tex]3y-18x=12[/tex]

[tex]3y=18x+12[/tex]

[tex]y=\frac{18x+12}{3}[/tex]

[tex]y=6x+4[/tex]

3. Re write both equations in the form y=mx+b, where m is the slope and b is the value of y when x=0 :

[tex]y=6x+2[/tex]

[tex]y=6x+4[/tex]

As both slopes are equal, and the values of b are different it means that the two lines are parallel and the system of equations does not have any solution.

Answer:

x=2.49

Step-by-step explanation:

3(x−0.50)=5.97

Distribute the 3

3x - 3*.5 = 5.97

3x -1.5 = 5.97

Add 1.5 to each side

3x -1.5+1.5 = 5.97+1.5

3x = 7.47

Divide each side by 3

3x/3 = 7.47/3

x=2.49

The calculation shows that 13 crates weigh 170 pounds less than 15 crates.

To find out how much less 13 crates of apples weigh than 15 crates of apples, we need to first determine the weight of the two different amounts of crates.

We know that one crate weighs 85 pounds.

So, for 15 crates, we multiply 15 by 85 to get the total weight:

= 15 crates x 85 pounds per crate = 1275 pounds

Next, we calculate the weight for 13 crates:

= 13 crates x 85 pounds per crate = 1105 pounds

Now, we subtract the weight of 13 crates from the weight of 15 crates:

= 1275 pounds - 1105 pounds = 170 pounds

Therefore, 13 crates of apples weigh 170 pounds less than 15 crates of apples.

Since you already know that two of the sides equal 10.8 mi which concludes to an isosceles triangle you'll add them which comes to 21.6 and lastly you just subtract 31 from 21.6 which is 9.4

Answer:

f(2) = 0

Step-by-step explanation:

Evaluate the function at x = 2.

f(x) = -3x^2 + 6x

f(2) = -3(2^2) + 6 * 2

f(2) = -3(4) + 12

f(2) = 0

Answer:

2, 240

Step-by-step explanation:

In the table, the values should be

Year 1   725  

Year 2   579

Year 3   696

Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.

[tex]\frac{112}{100} =\frac{x}{2000}[/tex]

We solve through cross multiplication of numerator and denominator of the opposite fraction.

[tex]112(2000)=100(x)\\224000=100x\\2,240=x[/tex]

Answer:

q1 = 3x^2 + 6x + 16

Step-by-step explanation:

2 || 3    0     4    -  32

           6    12       32

========================

     3    6    16         0

q(x) + r(x)/(x - 2)

r(x) = 0

q(x) = 3x^2 + 6x + 16

This does not factor down any further unless you have take complex number. The only real root isw

x = 2

Just in case you have done complex numbers

x2 = -1 + 2.0817i

x3 = -1 - 2.0817i
