What would this be for EBA

Answer:   -21x + 5y = 9

Step-by-step explanation:

The standard form says that  Ax + By=C  

So to covert y = 4.2x + 1.8 into  subtract 4.2 from both sides.

    y = 4.2x + 1.8

-4.2x   -4.2x

-4.2x + 1y = 1.8       Now it is written in standard form and to make the decimals integers we will multiply both sides by 10.

-4.2x(10) + 1y(10) = 1.8(10)

-42x + 10y = 18  which reduces to -21x + 5y = 9

Answer:

8 right angles

Step-by-step explanation:

1. If two lines are perpendicular then we know they form 4 right angles, so EP and AB from 4 right angles.

2. The question states that AB and CD are parallel. Since we know EP is intersecting AB and CD, we can say that EP is perpendicular to CD as well because of a theorem that states, "...that if there are two parallel lines in the same plane and there is a line perpendicular to one of them, then it is also perpendicular to the other one."

3. So because of that theroem, we can add another 4 right angles from the intersection of EP and CD.

4. When you add all the right angles together, you get 8 right angles in total.

Answer:

$0.50

Step-by-step explanation:

Suppose that a person  bought  six T-bone steaks that cost $15.99 per pound

The weight that is listed on the package is 5.77 pounds.

The scale that weighed the package is accurate to within 1/32 pound

Let assume x is the range of the  weight listed on the package,

Then:

[tex]|x-5.77| \leq \dfrac{1}{32} \ --- \ (1)[/tex]

Using the method of absolute value inequality;

[tex]- \dfrac{1}{32} \leq x -5.77 \leq \dfrac{1}{32}[/tex]

[tex]5.77- \dfrac{1}{32} \leq x \leq \dfrac{1}{32}+ 5.77[/tex]

[tex]5.77- 0.03125\leq x \leq 0.03125+ 5.77[/tex]

[tex]5.73875 \leq x \leq 5.80125[/tex]

The amount per kilogram undercharged or overcharged is :

[tex]=\dfrac{1}{32} \times 15.99[/tex]

= $0.50

=============================================

Explanation:

Any number you'll encounter so far in your math course will be a real number. This is until you get to something like [tex]\sqrt{-1}[/tex] which is a complex number, but your teacher may not have covered that chapter yet.

Anyways, -5 is a real number because we aren't taking the square root of a negative or anything like that.

-5 is also an integer, but that choice isn't listed. The set of integers is any positive or negative whole numbers, including 0 as well.

Furthermore, -5 is considered rational because -5 = -5/1. We can write -5 as a fraction of two integers where 0 is not in the denominator. With -5 being rational, it cannot be irrational. The term "irrational" means "not rational".

Answer:

(5, 1) (Answer C)

Step-by-step explanation:

Note that the second equation features x as a function of y:  x = y + 4.  We can substitute y + 4 for x in the first equation, obtaining:

y + 4 + y = 6

and then, after we combine like terms,

2y = 2, or y = 1.

x = y + 4, subbing 1 for y here results in x = 1 + 4, or x = 5

The solution is (5, 1) (Answer C)

Answer:

U'(-3, 1), M'(-1, 4), L'(-2, 0)

Step-by-step explanation:

To do a translation of 5 units up, add 5 to the y-coordinate of each point.

U(-3, -4) ----> U'(-3, -4 + 5) = U'(-3, 1)

M(-1, -1) ----> M'(-1, -1 + 5) = M'(-1, 4)

L(-2, -5) ----> L'(-2, -5 + 5) = L'(-2, 0)

Answer: The translated points are U'(-3, 1), M'(-1, 4), L'(-2, 0)

Answer:

The correct answer is z = -6.

Step-by-step explanation:

1/3 (2z + 6) = 1/4 (z - 2)

The first step I am going to take is to multiply both sides of the equation by 12 (the least common multiple of 3 and 4).  This will eliminate the fractions on both sides of the equations and make the numbers much easier to work with.

4 (2z + 6) = 3 (z - 2)

Next, we can use the distributive property to eliminate the parentheses.  This means multiplying each term inside the parentheses by the coefficient on the outside of the parentheses.

8z + 24 = 3z - 6

Now, we can subtract 3z from both sides of the equation.

5z + 24 = - 6

Next, we should subtract 24 from both sides of the equation.

5z = -30

Finally, we can divide both sides of the equation by 5.

z = -6

Therefore, the correct answer is z = -6.

Step-by-step explanation:

BDA = DBC+CBA

84=5x+3 + 6x-7

Combine like terms

84 = 11x-4

Add 4 to each side

84+4= 11x -4+4

88 =11x

Divide each side by 11

88/11 = 11x/11

8 = x

We want angle  ABC

ABC = 6x-7

       =6*8 -7

      =48-7

     =41

Answer:

∠ABC   = 41°

∠ DBC  = 43°

Step-by-step explanation:

6x-7 + 5x+3 = 84

6x + 5x = 84 - 3 + 7

11x = 88

x = 8

∠ABC   = 6x-7

           = 6*8 - 7

           = 48 - 7

           = 41°

∠ DBC = 5x + 3

           = 5*8 + 3

           = 40 + 3

            = 43°

Answer:

Altitude

Step-by-step explanation:

A segment from a vertex of a triangle at right angles to the opposite side is an altitude.

Thus AB is an Altitude

At time t, the first pool contains 50+2.3t gal of water, while the second pool contains 102.2-3.5t gal.

They contain the same amount of water when these quantities are equal:

50 + 2.3t = 102.2 - 3.5t

5.8t = 52.2

t = 9

so the pools have the same amount of water after 9 min have passed.

The pools will contain same amount of water in 9 minutes

Let the number of minutes that the pools contain the same amount of water be represented by t.

Since the first pool contains 50 gallons of water and is filling at a rate of 2.3 gallons per minute, then this will be:

= 50 + (2.3 × t)

= 50 + 2.3t ......... equation i

The second pool contains 102.2 gallons of water and is draining at a rate of 3.5 gallons per minute. This will be:

= 102.2 - (3.5 × t)

= 102.2 - 3.5t ........ equation ii

Equate both equations and this will be:

50 + 2.3t = 102.2 - 3.5t

Collect like terms

2.3t + 3.5t = 102.2 - 50

5.8t = 52.2

Divide both side by 5.8

5.8t/5.8 = 52.2/5.8

t = 9

In conclusion, they'll have same amount of water in 9 minutes

Answer:

42, 44, 46, 48

Step-by-step explanation:

Let x be the first number. Then x + x + 2 + x + 4 + x + 6 = 180.

We can combine like terms, getting 4x + 12 = 180.

Then we get x as 42.
