Answer:

x=37 Hope this helped <3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+7=2(x−15)

x+7=(2)(x)+(2)(−15)(Distribute)

x+7=2x+−30

x+7=2x−30

Step 2: Subtract 2x from both sides.

x+7−2x=2x−30−2x

−x+7=−30

Step 3: Subtract 7 from both sides.

−x+7−7=−30−7

−x=−37

Step 4: Divide both sides by -1

Answer:

[tex]\boxed {x = 37}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]x + 7 = 2(x - 15)[/tex]

-Use Distributive Property:

[tex]x + 7 = 2(x - 15)[/tex]

[tex]x + 7 = 2x - 30[/tex]

-Take [tex]2x[/tex] and subtract it from [tex]x[/tex]:

[tex]x + 7 - 2x = 2x - 2x - 30[/tex]

[tex]-x + 7 = -30[/tex]

-Subtract [tex]7[/tex] to both sides:

[tex]-x + 7 - 7 = -30 - 7[/tex]

[tex]-x = -37[/tex]

-Divide both sides by [tex]-1[/tex]:

[tex]\frac{-x}{-1} = \frac{-37}{-1}[/tex]

[tex]\boxed {x = 37}[/tex]

So, the value of [tex]x[/tex] is [tex]37[/tex].

Answer:

Step-by-step explanation:

(x, y) = (0, __) ⇒ x=0

y = 2(x - 5)² + 4

y = 2(0 - 5)² + 4

y = 2×25 + 4

y = 50 + 4

y = 54  ⇒  (0, 54)

Answer:

3/2

Step-by-step explanation:

Given y = 2x + 5, let's rewrite the equation in terms of x;

y = 2x + 5 => Bring 5 to the other side

2x = y - 5 => Divide either side by 2

x = (y - 5)/2

If we want to take the inverse, simply swap the variable's positions...

We have y = (x - 5)/2

Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1

f^-1(8) = (8 - 5)/2 = 3/2

Solution: 3/2

Answer:

Answer:

The integers:    53, 54, 55, 56

Step-by-step explanation:

Consecutive integers increase by 1, so if x is the smallest one, then the numbers are:

                      x,  x+1,  x+2,  x+3

the sum of the second and fourth: x+1 + x+3 = 2x+4

so:   2x + 4 = 110  ⇒  2x = 106   ⇒   x = 53

So the integers we are looking for:

                                                           53, 54, 55, 56

Answer: D

Step-by-step explanation:

it equals 15/12

Answer:

The answer is d :)

Step-by-step explanation:

5 + 4 + 3 + 2 +1 = 15

so D would equal 15/12

Answer:

y= 17x/7 - 87/7

The answer would be C is the slope is positive so I'm assuming it's a typo

Step-by-step explanation:

1.) When a slope is perpendicular that means that you do an opposite reciprocal so -7/17 turns into 17/7

2.) Use point slope form and solve for y

y-y1= m(x-x1)

y-7= 17/7 (x-8)

y-7= 17x/7 - 136/7

y= 17x/7 - 87/7

Answer:

Discrete

Step-by-step explanation:

Given the function:

f(x) = 100x + 300

Where ;

x = number of attendees

At least 4 students but no more than 9 students will attend the fieldtrip due to transportation and chaperone restrictions

Range of attendees :

4 ≤ x ≤ 9

Is this a discrete or continuous situation?

It is a discrete because the number of students who will attend the science weekend are finite and countable.

The number of attendees range from:

4, 5, 6, 7, 8 and 9.

then b=2

i am only do this by getting fun and do for help other

The value of [b] if a = 1/8 and c = 4 will be 33/16.

The mean of two numbers [a] and [b] is -

[M] = (a + b)/2

Given is that a = 1/8 and c = 4.

We have the following values -

a = 1/8

c = 4

Therefore, we can write the value of [b] as -

b= (1/8 + 4)/2

b = (33/8)/2

b = 33/8 x 1/2

b = 33/16

Therefore, the value of [b] if a = 1/8 and c = 4 will be 33/16.

Answer:

False

Step-by-step explanation:

All the angles in a triangle must add up to 180 degrees. Let's test this with the values given:

[tex]111+28+31[/tex]

[tex]= 170[/tex]

These angles only add up to 170°. Therefore, the answer is false, and these measures do not form a triangle.

Answer:

Step-by-step explanation:

the value of x is 37

the length of segment DG is 22 units

The length of segment AG is 44 units

the length of segment AD is 66 units

hope this helps (:

The length from the vertex to the centroid is twice the length from the

centroid to the midpoint of the opposite side.

Reasons:

The known parameters are;

The centroid of ΔABC = Point G

Segments [tex]\overline {AD}[/tex], [tex]\overline {BE}[/tex], and [tex]\overline {CF}[/tex] are the medians of ΔABC

Length of line segments [tex]\overline {DG}[/tex] = x - 15

Length of line segments [tex]\overline {GA}[/tex] = x + 7

Required:

The value of x, and lengths of the segments of median [tex]\overline {AD}[/tex]

The median is divided at the centroid of the triangle to ratio 2:1

[tex]Length \ of \ line \ segment \ \overline{GA} = \dfrac{2}{3} \times \overline{AD}[/tex]

Therefore;

[tex]\overline{AD} = \mathbf{\dfrac{3}{2} \times \overline{GA}}[/tex]

[tex]Length \ of \ line \ segment \ \overline{DG} = \mathbf{\dfrac{1}{3} \times \overline{AD}}[/tex]

Therefore;

[tex]\overline{AD} = 3\times \overline{DG}[/tex]

Which gives;

[tex]\dfrac{3}{2} \times \overline{GA} = 3\times \overline{DG}[/tex]

Therefore;

[tex]\dfrac{3}{2} \times (x + 7) = 3\times (x - 15)[/tex]

3·x + 21 = 6·x - 90

21 + 90 = 6·x - 3·x

111 = 3·x

3·x = 111

[tex]x = \dfrac{111}{3} = 37[/tex]

x = 37

[tex]\overline {DG}[/tex] = x - 15

The length of line segment [tex]\overline {DG}[/tex] = 37 - 15 = 22

[tex]\overline {GA}[/tex] = x + 7

Length of line segment [tex]\overline {GA}[/tex] = 37 + 7 = 44

[tex]\overline {AD}[/tex] = [tex]\overline {DG}[/tex] + [tex]\overline {GA}[/tex]

Therefore;

Length of line segment [tex]\overline {AD}[/tex] = 22 + 44 = 66
