please help me with this question!!

Answer:

Step-by-step explanation:

If E is 3 and EG is 6, then ...

  G = E ± EG = 3 ± 6

  G = -3 or 9

If E is 3 and EX is 12, then ...

  X = E ± EX = 3 ± 12

  X = -9, or 15

__

If X and G have the same sign, then G will be the midpoint of EX. If not, then G is not the midpoint.

That is, -3 is halfway between -9 and 3, just as +9 is halfway between 3 and +15. On the other hand, -3 is not between 3 and 15; nor is 9 between 3 and -9.

Answer:

-23

Step-by-step explanation:

Let first negative integer = x

The second = x +5

Their product = 126, hence,

x * (x +5) = 126

x^2 + 5x = 126

x^2 + 5x - 126 = 0

Two numbers whose product gives - 126 and sun gives 5

x(x + 14) - 9(x+14) =0

(x - 9) = 0 or (x + 14) = 0

x = 9 or x = - 14

Since x is said to be a negative integer,, the our x = - 14

First integer = - 14

Second integer = (x + 5) = (-14 + 5) = - 9

Sum of both integers :

-14 + - 9 = - 23

Answer:

[tex]y=\frac{1}{2}x-3[/tex]

Step-by-step explanation:

Start by writing the equation out as it is given in the question (in this case, in standard form).

[tex]3x-6y=18[/tex]

Next, subtract [tex]3x[/tex] from both sides.

[tex]3x-3x-6y=18-3x\\-6y=18-3x[/tex]

Switch around the [tex]18[/tex] and the [tex]-3x[/tex].

[tex]-6y=-3x+18[/tex]

Finally, divide the equation by [tex]-6[/tex] to get rid of the [tex]y-variable[/tex] coefficient, which is [tex]-6[/tex].

[tex]\frac{-6y}{6}=\frac{-3x+18}{-6}\\y=\frac{1}{2}x-3[/tex]

As shown in that last step, the equation is slope intercept form is: [tex]y=\frac{1}{2}x-3[/tex]

Answer:

y = 1/2x - 3.

Step-by-step explanation:

3x - 6y = 18

-6y = -3x + 18

Divide through by -6:

y = 1/2x - 3.

Answer:

40x + 90y <2400

18x + 30y < 500

Step-by-step explanation:

Lee washes houses. It takes him 40 minutes to wash a one-story home, and he uses 18 gallons of water. Power washing a two-story home takes less than 90 minutes, and he uses 30 gallons of water. Lee works no more than 40 hours each week, and his truck holds 500 gallons of water. He charges $90 to wash a one-story home and $150 to wash a two-story home. Lee wants to maximize his income washing one- and two-story houses. Let x represent the number of one-story houses and y represent the number of two-story houses. What are the constraints for the problem

Let

x=one story houses

y=two story houses

The constraints are the following:

1. Lee works no more than 40 hours each week.

40 hours=40 × 60 minutes

=2400 minutes

2. Lee's truck holds 500 gallons of water.

it takes Lee 40 minutes and 18 gallons of water to wash a one-story house.

it takes Lee 90 minutes and 30 gallons of water to wash a two-story house.

First constraint:

40*x + 90*y < 2400

40x + 90y <2400

Second constraint:

18*x + 30*y < 500

18x + 30y < 500

Answer:

[tex] ST = 5\sqrt{2} [/tex]

Step-by-step explanation:

Given:

S(-3, 10)

T(-2, 3)

Required:

ST

SOLUTION:

Use the distance formula, [tex] \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], to find ST.

Where,

[tex] S(-3, 10) = (x_1, y_1) [/tex]

[tex] T(-2, 3) = (x_2, y_2) [/tex]

[tex] ST = \sqrt{(-2 -(-3))^2 + (3 - 10)^2} [/tex]

[tex] ST = \sqrt{(1)^2 + (-7)^2} [/tex]

[tex] = \sqrt{1 + 49} [/tex]

[tex] = \sqrt{50} = \sqrt{25*2} [/tex]

[tex] ST = 5\sqrt{2} [/tex]

Answer:

120[tex]m^{3}[/tex]

Step-by-step explanation:

The formula for V (volume) is l*w*h (length*width*height).

You can substitute each part of the formula for the given units.

6m*2m*10m = V

6m*m2 = 12[tex]m^{2}[/tex]

12[tex]m^{2}[/tex]*10m = 120[tex]m^{3}[/tex]

120[tex]m^{3}[/tex] = V

Answer:

4%

Step-by-step explanation:

Since percentages are counted with % (100), we multiply 50 by 2 to get 100. We also 48 by 2 to get 96. Then we subtract 96 from 100 to get 4%.

48 increases by 4% o get 50.

Answer:

see below explanation

Step-by-step explanation:

1.  9 (x - 11) = 9

   9x - (9 * 11) = 9

   9x - 99 = 9

   x = 12

2.  4 (3x - 2) = 52

    (4 * 3x) - (4 * 2) = 52

    12x - 8 = 52

    x = 5

3.  44 = 2 (3x - 5)

    44 = (2 * 3x) - (2 * 5)

    44 = 6x - 10

    x = 9

4.  2x- 4/5 = 4

    2x - 2²/5 = 4

    5(2x) + (-2²)  /  5  = 4

    x = 12 / 5

5.   3x + 2/2 = 13

     3x + 1 = 13

    (3x + 1) + (-1) = 13 + (-1)

    x = 4

6.   4x -5/5 = 3

      4x - 1 = 3

      (4x - 1) + 1 = 3 + 1

      x = 1

7.   10x + 4/7 = 8

     10x + 2²/7  = 8

     7(10x) + 2²  /  7   = 8

     x = 26 / 35

8.    6x - 1/2 = 1

       2(6x) + (-1) / 2 = 1

      ((2 * 6x) - 1 ) / 2 = 1

      x = 1/4

D. 4 hundredths

Step-by-step explanation:

Hello!

The second digit after the decimal point is 4 is shown by

0.04

The points after a decimal point go tenths, hundredths, thousandths etc.

The answer is D. 4 hundredths

Hope this helps!

Answer:

4 hundredths

Step-by-step explanation:

For values of decimals one should note that each additional digit after the decimal is a multiple of (1/10).

Using this knowledge, the first digit would be tenths, the second digit hundredths, the third digit thousandths, etc.

Hence a 4 in the second digit after the decimal would be equivalent to 4 * (1/100) = (4/100) or 4 hundredths.

Cheers.

A polynomial is a mathematical expression in sum of powers with one or more variables multiplied by coefficients.

a) 3x² - 5x + 7 is a polynomial

b) x² + 2x - 1 is a polynomial

Answer:

a= 18 girls in the class, b= 20 boys and 15 girls, 12 oranges better price.

Step-by-step explanation:

for question a, there are 18 girls in the class, this is how i worked it out:

the ratio of boys to girls is 4:3.

there are 24 boys.

24 is 6 times more than 4.

if boys are 6 times more than the original ratio, we also have to times the amount of girls by 6.

6x3= 18.

for question b i got 20 boys and 15 girls, this is how i did it.

there are 35 students in total.

4:3= boys to girls.

4+3=7

7 goes into 35 five times.

ratio of boys to girls is 4:3 so 5x4 for boys = 20 and 3x5 for girls = 15.

answer= 20 boys and 15 girls.

12 oranges is a better deal, this is how i worked it out.

it is 60 for 12 oranges.

it is 48 for 8 oranges.

12x5= 60 , 8x6=48.

you only have to times 12 by 5 to get it to the price but you have to times 8 by 6 to get it to the price, proving that 12 oranges for 60 is a better deal.

Answer:

Find the ratio of hops to distance traveled (1: 1.5), then multiply 150 by 1.5.

Step-by-step explanation:

A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft) 20 30 50 75 80 120 150 ?

Which statement correctly explains how to find the distance traveled after 150 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. Find the ratio of hops to distance traveled (1:1.5), then multiply 150 by 1.5. Find the ratio of hops to distance traveled (1:1.5), then divide 150 by 1.5.

Solution:

The table is:

No. of hops Distance traveled

20 30

50 75

80 120

150 ?

From the table, for every 30 increase in the number of hops, the distance travelled increase by 45 feet

Find the slope of the line:

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

m=slope of the line

y2-y1 = change in distance travelled

x-2 - x1 = Change in number of hops

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

m = (75-30) / (50-20)

=45 / 30

m = 1.5

Then, the line is:

y = 1.5x

We substitute x = 150

y = 1.5x

y = 1.5 × 150

y = 225

Answer: Hi!

To simplify this expression, we will combine like terms.

Plane 'S'

Step-by-step explanation:

Since a plane is a two dimensional surface on which infinitely many points may lie.

In the picture attached, two planes (two dimensional) have been given.

Plane S

Plane T

Plane 'S' contains three points A, B and C and plane 'T' contains points D and E.

Therefore, the plane which contains points A, B and C is Plane 'S'.

The plane that contains points A, B and C is the plane S.

A plane is simply a 2-dimensional surface or figure.

The above definition of a plane means that, there are only two planes in the given figure.

These planes are:

Hence, the plane which contains points A, B and C is plane S.
