Elan Coil [88]1 year ago
4 0

Answer:

8

Step-by-step explanation:

Given algebraic expression:

5(x - 1) - 2

To:

Evaluate this expression using x = 3

Solution:

  • 5(x - 1) - 2

Evaluate by plugging x = 3 to this expression:

  • 5(3-1)-2

Simplify using PEMDAS.

  • 5(2)-2
  • 10-2
  • 8

<u>We can conclude:</u>

By evaluating x = 3 to the given expression,the answer will be 8.

How many 5 1/4 ounce glasses can be completely filled from a 33 1/2 ounce container of juice?
geniusboy [140]
You need to divide.
We are dividing the mixed numeral 33 1/21 by the mixed numeral 5 1/4.

(33 1/2 ) / (5 1/4) =

The first step is to change the two mixed numerals into improper fractions.
33 1/2 = 67/2, and 5 1/4 = 21/4

= (67/2) / (21/4)

Now we are dividing the fraction 67/2 by the fraction 21/4.
To divide a fraction by a fraction, rewrite the first fraction, change division intro multiplication, and flip the second fraction. To divide 67/2 by 21/4, we multiply 67/2 by 4/21.

= 67/2 * 4/21

To multiply fractions, multiply together the numerators, and multiply together the denominators. 67 * 4 = 268; 2 * 21 = 42

= 268/42

Using a calculator, 268/42 = 6.38095...

You can fill 6 full glasses.

Which algebraic expression represents "the difference of 54 and a number"?
atroni [7]

\huge{\boxed{54-x}}

The difference is the result of a subtraction problem.

We are given two values that are being subtracted: 54 and a number, represented by x

So, represent this mathematically with \boxed{54-x}.

What can be concluded about the line represented in the table? Check all that apply. x y –6 –7 2 –3 8 0 The slope is 2. The slop
Stels [109]
The first thing we must do for this case is to find the equation of the line.
 y-yo = m (x-xo)&#10;
 We have then:
 m = (y2 - y1) / (x2-x1)&#10;&#10;m = (-3 - 0) / (2-8)&#10;&#10;m = 1/2
 We choose an ordered pair:
 (xo, yo) = (8, 0)&#10;
 Substituting values:
 y-0 = (1/2) (x-8)&#10;&#10;y = (1/2) x - 4
 
 From here we conclude:

 Intersection with y:
 
We evaluate x = 0 in the function:
 y = (1/2) (0) - 4&#10;&#10;y = -4

 Slope of the line:
 m = 1/2&#10;

 Point (-2, -5):
 
We evaluate the value of x = -2 and the value of y = -5
 -5 = (1/2) (- 2) - 4&#10;&#10;-5 = -1 - 4&#10;&#10;-5 = - 5
 The equation is satisfied.

 Point (8, 0):
 
It is part of the table, therefore belongs to the line.

 Answer:
 
The slope is 1/2
 
The y-intercept is -4.
 
The points (-2, -5) and (8, 0) are also on the line.
