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:

-2 sqrt (2) /3

Step-by-step explanation:

sin = -1/3 its in the 3rd quadrant so sin is negative cos is negative

sin^2 O + cos ^2 O = 1

1 - (1/9) = cos^2 O

(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:

-4.75

Step-by-step explanation:

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

So applying the formula

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

= -38/8 = -4.75

Answer:

32.5cm

Step-by-step explanation:

Using the formula A=h_b*b/2

We get 5*13/2=32.5

Answer:

Step-by-step explanation:

(1,8) (-1,-2)

Slope: (-2-8)/(-1-1) = -10/-2 = 5

y -8 = 5 (x - 1)

y - 8 = 5x - 5

y = 5x +3

Answer:

x=0 , x = 1/2

Step-by-step explanation:

(4x-1)=1 —> 4x-1=1—> 4x=1+1—> 4x=2 —> x=2/4 —> x= 1/2

-(4x-1)=1—>-4x+1=1—> 4x= 1-1 —> x=0

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

I hope I helped you^_^

Answer:

x = 5

Step-by-step explanation:

7(2 - 6x) = -196

14 - 42x = -196

14 - 42x - 14 = -196 - 14

-42x = -210

-42x/-42 = -210/-42

x = 5

Answer:

5

Step-by-step explanation:

7(2 - 6x) = -196                Remove the brackets

7*2 - 7*6x = - 196

14 - 42x = - 195               Subtract 14 from both sides

-42x = - 196 - 14

-42x = - 210                    Divide by 42

x = - 210 / - 42

x = 5  

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.

I hope this was helpful, keep learning! :D

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

You need to do the thing inside the absolute value brackets before converting it to a positive.

Answer: -4

Step-by-step explanation:

Start with -6, since there is nothing to solve in the parenthesis.

Subtract -2 from -6, which will get you -4.

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.

I don't understand the question

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)
