a=bx+cx+d for x. HELP ME

Answer:

Step-by-step explanation:

Oof, all 6?  That's not fun.  

I'm going to show you one for the first bunch, (4-12) and hopefully you can get the rest.  If not let me know and I can more carefully work you through some others on here.

4)  So first we need the angle.  How do we find that?  Well, we know it's somewhere between 270 and 360 degrees (or 3pi/2 and 2pi radians) since it's in the fourth quadrant.    The method to finding the angle is ifferent for each quadrant, but it's nice to know around where you'll get.  Anyway,, if we take 360 and subtract that little space  that is unlabeled  we will know  the rest.    Hopefully that makes sense, but let me know if not, it's important to understand.  Maybe think of what happens if you add the two together, you get around the whole circle then.  

Anyway, to find that little sliver, we are going to construct a right triangle wherethe x axis is one side.  If you draw a line connecting point p and the x axis you have this right triangle.  I am going to call this sliver we don't know s.  ANyway, now we use trig here.  

s = arcsin(3/5) (you can find 5 pretty easily but let me know if you don't see it.)

You may think to use -3 instead of 3, and  it wouldn't be a huge mistake, it will just give you the negative version of what we want.  

Anyway, now we know theta is 360-s (or 2pi-s).  You can solve s or leave it as arcsin(3/5) so you don't have to round.

Now we can solve the trig functions.  If you don't know the sum and difference trig identities  you will have to round.  They are pretty simple formula though.  For instance, sin(2pi - arcsin(3/5)) = sin(2pi)cos(arcsin(3/5))-cos(2pi)sin(arcsin(3/5)) = 0 - 3/5 = -3/5  You will also want to know that s = arcsin(3/5) = arccos(4/5) = arctan(3/4).  ROunding will get you close but not exact.

Again, let me know ifyou need any more help, they should just be a lot of doing the same thing over and over and over again though.  

14)  For 14 and 16 you just need to know how the graphs of sin, cos and tan look.  Is this something you have trouble with?  Like could you draw the graphs at the intervals of increasing/ decrasing and all.  if not I can give a quick explanation.

Answer:

f(a + 2) = 3a + 21

Step-by-step explanation:

f(x) = 3(x+5)

x = a + 2

f(a + 2) = 3(a + 2 + 5)

f(a + 2) = 3(a + 7)

f(a + 2) = 3a + 21

Answer: [tex]\pm\frac{1}{1}, \pm\frac{1}{2},\pm\frac{2}{1},\pm\frac{3}{1}, \pm\frac{3}{2}[/tex]

Step-by-step explanation:

We can use the Rational Root Test.

Given a polynomial in the form:

[tex]a_nx^n +a_{n- 1}x^{n - 1} + … + a_1x^1 + a_0 = 0[/tex]

Where:

- The coefficients are integers.

- [tex]a_n[/tex] is the leading coeffcient ([tex]a_n\neq 0[/tex])

- [tex]a_0[/tex] is the constant term [tex]a_0\neq 0[/tex]

Every rational root of the polynomial is in the form:

[tex]\frac{p}{q}=\frac{\pm(factors\ of\ a_0)}{\pm(factors\ of\ a_n)}[/tex]

For the case of the given polynomial:

[tex]2x^7+3x^5-9x^2+6=0[/tex]

We can observe that:

- Its constant term is 6, with factors 1, 2 and 3.

- Its leading coefficient is 2, with factors 1 and 2.

 Then, by Rational Roots Test we get the possible rational roots of this polynomial:

[tex]\frac{p}{q}=\frac{\pm(1,2,3,6)}{\pm(1,2)}=\pm\frac{1}{1}, \pm\frac{1}{2},\pm\frac{2}{1},\pm\frac{3}{1}, \pm\frac{3}{2}[/tex]

The possible rational roots of the polynomial equation [tex]0 = 2x^7 + 3x^5 - 9x^2 + 6.[/tex] are ±1, ±2, ±3, ±6, ±1/2, ±1, ±3/2, and ±3.

Given equation [tex]0 = 2x^7 + 3x^5 - 9x^2 + 6[/tex].

The Rational Root Theorem states that if there are any rational roots (fractions in the form p/q) for the polynomial equation, then p must be a factor of the constant term (in this case, 6), and q must be a factor of the leading coefficient (in this case, 2).

So, the possible rational roots (fractions p/q) for this polynomial are all the combinations of p and q, where:

p is a factor of 6, and

q is a factor of 2.

The factors of 6 are ±1, ±2, ±3, and ±6.

The factors of 2 are ±1 and ±2.

So, the possible rational roots are all the combinations of these factors:

±1/1, ±2/1, ±3/1, ±6/1, ±1/2, ±2/2, ±3/2, and ±6/2.

Simplify these fractions:

±1, ±2, ±3, ±6, ±1/2, ±1, ±3/2, and ±3.

Answer:

it will take 80 minutes

Step-by-step explanation:

Total no.of rows=10

Time taken to plant 3 rows = 24 min

So,find time taken for planting 1 row

which is =24/3=8min

total time taken to plant 10 rows=8×10=80min

so it takes 80 min to plant 10 rows

It takes 8 minutes to plant one row of the garden and therefore to plant all 10 rows, it will take a total of 80 minutes.

This question is asking for the total time it would take to plant a garden with 10 rows of vegetables if it took 24 minutes to plant the first 3 rows. First, we need to understand how long it takes to plant one row. To find this out, we divide the total amount of time (24 minutes) by the number of rows planted in that time (3 rows). This gives us how long it takes to plant one row: 24 minutes ÷ 3 rows = 8 minutes per row. Now that we know this, we can work out how long it would take to plant all 10 rows. We do this by multiplying the time it takes to plant one row (8 minutes) by the total number of rows we need to plant (10 rows). This gives us the total time: 8 minutes per row x 10 rows = 80 minutes. So, it would take 80 minutes to plant all 10 rows of the garden.

This set of problems revolves around simplifying monomials by adding, subtracting, and multiplying them. For example, the subtraction of -2x from -8x would simply result into -6x. A similar approach can be used for other problems.

The question primarily deals with exponents and exponential functions, specifically about simplifying monomials by using the rules of addition, subtraction, and multiplication. Additionally, it wants us to utilize the product rule to simplify further monomials. For instance if we look at problem 10, which asks to subtract -2x from -8x. The subtraction of a negative number is equivalent to addition. So, -8x - (-2x) becomes -8x + 2x which simplifies to -6x. This is just an example, and the similar approach can be used to solve the remainder of the problems.

To solve the system of equations y = 2x - 5 and y = x² - 5, use algebraic methods such as factoring or the quadratic formula to find the x-values. Then plug these values back into one of the original equations to find the corresponding y-values. The solutions to the system of equations are (5, 5) and (-2, -9).

To solve the system of equations y = 2x - 5 and y = x² - 5, we can set the two equations equal to each other since they both equal y. This gives us the quadratic equation x² - 2x - 10 = 0. We can solve this quadratic equation by factoring, completing the square, or using the quadratic formula.

Factoring the quadratic equation, we get (x - 5)(x + 2) = 0. This means that x - 5 = 0 or x + 2 = 0. Solving these two equations gives us x = 5 or x = -2. Substituting these values back into either of the original equations, we can find the corresponding y-values. For x = 5, y = 2(5) - 5 = 5. For x = -2, y = 2(-2) - 5 = -9. Therefore, the solutions to the system of equations are (5, 5) and (-2, -9).

Answer:

m<AFE​ =  128°.

Step-by-step explanation:

Step 1: Find the value of x

Angle EFD + Angle DFC = Angle EFC

5x + 6 + 19x - 15 = 17x + 19

24x - 9 = 17x + 19

7x = 28

x = 4

Step 2: Find all angles

Angle AFB=Angle EFD= 5x + 6

5(4) + 6 = 26°

Angle DFC = 19x - 15

19(4) - 15 = 61°

Step 3: Find angle AFE

Line BD is a straight line and all angles on a straight line are equal to 180°.

Angle AFB + Angle AFE + Angle EFD = 180°

26 + BFC + 26 = 180°

BFC = 180 - 52

BFC = 128°

Therefore, m<AFE​ is equal to 128°.

!!

The measure of m<AFE  if m<EFD = (5x+6)°, m<DFC = (19x-15)°, and m<EFC = (17x+19)° is 128degrees

Angle is the point where two or more lines meet. From the given diagram:

m<EFC = m<EFD + m<DFC

Given the following:

m<EFC = 17x + 19

m<EFD = 5x+6

m<DFC = 19x - 15

Substitute the given values into the expression

17x + 19 = 5x + 6 + 19x - 15

17x - 5x - 19x = -19 - 9

12x - 19x = -28

-7x = - 28

x = 28/7

x= 4

Get the angle m<AFE

m<AFE  + m<ABF + m<EFD = 180

Since  <AFB = <EFD

m<AFE  + m<EFD + m<EFD = 180

m<AFE + 2m<EFD = 180

m<AFE + 2(5x+6) = 180

m<AFE + 2(5(4) + 6) = 180

m<AFE +2(26) = 180

m<AFE + 52 = 180

m<AFE = 180 - 52

m<AFE = 128 degrees

Hence the measure of m<AFE is 128degrees
