Answer:

m<DBC = 109

Step-by-step explanation:

8x-27=6x+7

8x=6x+34

2x=34

x=17

8(17)-27= 109

Answer: 109

Step-by-step explanation:

i'm not entirely sure of this answer as its been a while since ive done problems like this, however, i think the steps to solve are setting (8x-27) equal to (6x+7). Once you do that, you can solve for x. Substitute x into angle DBC to find the answer.

Answer:

1,440

Step-by-step explanation:

Because 360*4=1,440

Answer:

$1440

Step-by-step explanation:

What you're going to want to do is multiply 4 by 36 at first. This is going to get you to 144. If you really wanted to break it down, you can multiply 4 by 3, place a zero at the end, multiply 4 by 6, and add the totals. Next, since the question is 4x360 and not 36, we will need to place a zero at the end of the product. This will get you 1440. And so, the answer is $1440.

Answer:

-4.75

Step-by-step explanation:

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

So applying the formula

(-29-9)/(15-7)

= -38/8 = -4.75

Hello there!

We are given the equation:

[tex] \displaystyle \large{ |4x - 1| = 1}[/tex]

Definition/Property

[tex] \displaystyle \large{ |a| = \sqrt{ {a}^{2} } } \\ \displaystyle \large{ |a| = b \longrightarrow a = \pm b} \\ \displaystyle \large{ |a| = \begin{cases} a \: \: (x \geqslant 0) \\ - a \: \: (a < 0) \end{cases}}[/tex]

First, cancel the absolute value sign and write plus-minus beside 1.

[tex] \displaystyle \large{ |4x - 1| = 1} \\ \displaystyle \large{ 4x - 1 = \pm 1} \\ [/tex]

Break in two cases.

[tex] \displaystyle \large{ 4x - 1 = \begin{cases} 1 \\ - 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 1 + 1 \\ - 1 + 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 2 \\ 0 \end{cases}} \\ \displaystyle \large{ x = \begin{cases} \frac{2}{4} \\ \frac{0}{4} \end{cases}}[/tex]

Therefore, x = 0 or 1/2

Let me know if you have any questions!

Topic: Absolute Value Function - Equations

Answer:

The value of x is 15

Step-by-step explanation:

2x + 3(x - 10) = 45

2x + 3x - 30 = 45

5x - 30 = 45

Now, Add 30 both sides we get,

5x - 30 + 30 = 45 + 30

5x = 75

Now, Divide 5 from both sides we get,

5x/5 = 75/5

x = 15

Thus, The value of x is 15

Hence, Option A is correct

(g + 4) - 3g = 1 + g

or, g + 4 - 3g = 1 + g

or, -2g + 4 = 1 + g

or, -2g - g = 1 - 4

or, -3g = -3

or, g = -3/-3

or, g = 1

The value of g is 1.

Answer:

Step-by-step explanation:

since AB and BC are perpendicular so AB.BC=0, (scalar product)

AB=(-4, -6), and BC=(xc+2, yc-8)

AB.BC= -4x-8-6y+48 =0

so the equation of BC is 2x+3y-20=0

C is on the line BC, so 2xc+3yc-20=0, but yc=0, so xc=20/2=10

AB and CD are parallel, so det(AB, CD)=0

AB and AD are perpendicular so AB.AD=0

AB=(-4, -6) and CD =(x-10, y), AD= (x-2, y-14)

det(AB, CD)=0

             x-10-y = 0 equivalent to  x-y = -10

AB.AD=0

 -4x+8-6y+84=0  equivalent to   2x+3y=44

let's solve

x-y = -10

2x+3y=44

-5y = -64, y = 64/5, x= -10+64/5=14/5

finally  D(14/5, 64/5)

Answer:

q = 3.5

Step-by-step explanation:

Start by distributing the 5

-15 = 15q - 50 - 5q

Combine like terms

-15 = 10q - 50

Add 50 to both sides

35 = 10q

Divide by 10 to isolate q

35/10 = q

q = 3.5

Answer:

q=3.5 or 4

Step-by-step explanation:

-15=5(3q-10)-5q

-5=15q-50-5q

-15+50=15q-5q

35=10q

Divide both sides by 10.

35÷10=10q÷10

3.5=q

Therefore,q= 3.5

Answer: For every three students in band, one will be selected for All-State band.

Step-by-step explanation: The easiest way to explain it is to reduce 600 and 200 by the same number until you can't anymore. I know it sounds like I'm coming up with this off the top of my head, but rest assured that I'm not.

Answer: Y = 3500, X = 16

Step-by-step explanation:

Your maximum Y-value is 3000, or, the price of your car, so that could be the answer that's being looked for. However, it's always a good idea to leave a little extra space on the end of the graph so that you can show that your line ends instead of continuing onwards.

Your maximum X-value is 15, or, the number of months it would take to pay off the car (200 dollars per month, until you reach 3000 dollars), but again, it's always smart to leave a little buffer space so that you can see that the graph actually ends.

The answer your teacher wants is probably that the maximum Y-value should be 3000 and the maximum X-value should be 15, but if you have to actually graph this equation yourself and want it to be understood that your graph is a line segment and not a line (the difference being that a line is infinite and a line segment has two ends), you will want to show that by not ending the graph at the same spot as the line segment and instead extending it a little further.

    To solve this problem form the system of equations as per statements given in the question then get the answer by solving them.

    Number of bushes in garden one were 55 and in second garden 11 originally.

   Let the number of raspberry bushes in one garden = x

And the number of raspberry bushes in second garden = y

So the equation for the given statement will be,

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

Therefore, equation for this statement will be,

(x - 22) = (y + 22)

x - y = 22 + 22

x - y = 44 ------(2)

Substitute the value of x from equation (1) to equation (2)

5y - y = 44

4y = 44

y = 11

Substitute the value of 'y' in equation (1),

x = 5(11)

x = 55

                   Therefore, Number of bushes in garden one were 55 and in second garden 11 originally.

Hi! I'm happy to help!

A square root, means:

√x=y

This means that:

x=y·y=√x·√x

When we have the square button, it causes everything to be multiplied by itself once.

√x²=x

Due to the fact that the squared symbol is outside of the parenthesis, it causes both the square toot of 2, and the square root of 3, to be squared.

Now that we know this, √2², and √3²= 2, and 3.

This is why we get 2+3.

2+3=5, which is pretty self explanatory.
