which number line shows all the values of X that make the inequality -3x+1<7 true?

a
b
c
d

Answer:

first you need to set up the equation which is 20+2x=44 then isolate 2x by doing the inverse operation for 20 which is -20 and add them to both sides which would now give you 2x=24 so divde 24 by 2 which is 12, x=12 answer 12ml

Answer:

[tex]y = \frac{7}{6} x[/tex]

Step-by-step explanation:

Slope-intercept form is

[tex]y = mx + b[/tex]

Where m = slope,

and b = y-intercept.

The problem states that the slope is [tex]\frac{7}{6}[/tex], and it also states that one point on the line is the origin. (0, 0)

Because the origin crosses the y-axis at point 0, we know that the y-intercept is 0.

All that's left to do is plug these values into the slope formula.

[tex]y = \frac{7}{6} x + 0[/tex]

We can then simplify the equation even more.

[tex]y = \frac{7}{6} x[/tex]

Answer: The value of x= 18

Step-by-step explanation:

Given: In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10.

The sum of all angles of a triangle is 180°.

Therefore, in triangle EFG

∠E + ∠F +∠G= 180°

⇒ 8x-16 +x+8+ 2x-10 =  180

⇒ 11x-18= 180

⇒ 11x = 180+18

⇒11x=198

⇒ x= 18   [Divide both sides by 11]

Hence, the value of x= 18

(n + 1) (2n - 7)

Step-by-step explanation:

2n^2 - 5n - 7

AC= 2 * -7 = -14

                -7 + 2 = -5

      2n^2 - 7n      + 2n - 7

     1n(2n - 7)       1(2n - 7)

(n + 1) (2n - 7)

Answer:

-8n

Answer:

62

Step-by-step explanation:

5 * 3 * 2 = 30

3 * 2 * 2 = 12

5 * 2 * 2 = 20

30 + 12 + 20 = 62

Answer:

Step-by-step explanation:

10x + 15y = -90

15y = -10x - 90

y = (-10/15)x - 90/15 = -⅔x - 6

The required equation is -(2/3)x - 6 which is equivalent to the given equation 10x + 15y = −90, which is the correct answer that would be option (A).

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

The equation is given in the question

10x + 15y = -90

We have to determine whether the equation is equivalent to 10x+15y=−90 when it is solved for y

As per the given equation,

⇒ 10x + 15y = -90

Rearrange the term of variables and solve for y

⇒ 15y = -10x - 90

Divided by 15 into both sides of the above equation,

⇒ y = (-10/15)x - 90/15 =

Reduce the fraction to the simplest form,

⇒ y = -(2/3)x - 6

Therefore, the required equation is -(2/3)x - 6 which equivalent to given equation 10x + 15y = −90.

Answer:

Step-by-step explanation:

One

v^2 - 16

This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.

The square root of v^2 = v

The square root of 16 = 4

You get (v + 4)(v - 4)

Let's see what happens when you expand it.

Look what happens when you add these 4 terms together.

is what is left. The two middle terms cancel out.

Two

This one is a perfect square

w^2 + 16w + 64

(w + 8)(w + 8)

Notice both factors are the same. You might wonder how I new that.

w^2 is a perfect square so take the square root.  ....   v      

64 is a perfect square so take the square root    .....    8

Now you have to work backwards to see if it is right.

Adding you get w^2 + 16w + 64 which is what you started with.

Answer:

  A"(-6, 3)

  B"(-9, 0)

  C"(-5, -1)

Step-by-step explanation:

We presume the first transformation is a translation 4 units right and 1 unit up:

  (x, y) ⇒ (x+4, y+1)

The second transformation negates the x-coordinate, so the two transformations together have the rule ...

  (x, y) ⇒ (-(x+4), y+1)

Then the transformed points are ...

 A"(-6, 3)

  B"(-9, 0)

  C"(-5, -1)

Answer:

21/50, 42%

Step-by-step explanation:

The total times the coin was flipped is 50 and the number of times it landed on tails is 50-29=21. So we need to divide 21 by 50, which gives us 42%.

Given:

The table of values.

v and x are in direct proportion.

To find:

The formula connecting v and x.

Solution:

(a)

v and x are in direct proportion.

[tex]v\propto x[/tex]

[tex]v=kx[/tex]            ...(i)

Where, k is the constant of proportionality.

Putting v=13.6 and x=32.64, we get

[tex]13.6=k(32.64)[/tex]

[tex]\dfrac{13.6}{32.64}=k[/tex]

[tex]\dfrac{5}{12}=k[/tex]

Putting the value of k in (i), we get

[tex]v=\dfrac{5}{12}x[/tex]

Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].

(b)

Putting v=n and x=8.16, we get

[tex]n=\dfrac{5}{12}(8.16)[/tex]

[tex]n=3.4[/tex]

Therefore, the value of n is 3.4.

Answer:

326

Step-by-step explanation:

First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.

Answer: 180 ft²

Step-by-step explanation:

The rest of the question is:

The living room is 18 feet wide and 10 feet long.

The floor seems to take the shape of a rectangle because it has one dimension being longer than the other.

As this is a rectangle, the floor area will be calculated by the formula:

= Length * Width

= 10 * 18

= 180 ft²

Answer:

2

Step-by-step explanation:

so (+35) can be written as 35 because it's automatically already positive. +(-33) can be written as -33 because of one negative sign and one positive sign (if it was two negative or two positive, it would be positive). it's the same as 35-33, and 35-33=2.

Answer:

(+35) + (-33)

⇒ 35-33

⇒2
