Answer:
0
Step-by-step explanation:
The expression we are given is (2 * x - 4).
We need to find the value of expression when x = 2.
Let's substitute 2 in as x.
Now our expression is (2 * 2 - 4).
First, let's multiply our 2 with our substituted 2.
1. 2 * 2 = 4
We're left with (4 - 4).
Finally, let's evaluate this expression.
2. (4 - 4) = 0.
Our answer is 0.
So (2 * x - 4) when x = 2 is 0.

Answer:
1. 14x and 7 and 9x and 3
2. 0x
3. 4
Step-by-step explanation:
Step 1: Distribute
First, multiply 7 by 2x and 1 to get 14x and 7. Then multiply -3 by 3x and 1 to get -9x and -1
Step 2: Combine like variable terms
Combine 14x, -5x, and -9x, to get 0x.
Step 3: Combine like constant terms
Combine 7 and -3, to get 4.
Emma was about to finish grocery shopping when she noticed that cans of soup were on sale. Her total bill for groceries would be $89.61 if she purchased two cans of soup and $94.98 if she bought five cans. Which equation could be used to describe Emma's grocery bill, B, in dollars as a function of the number of cans, C, purchased?
B(C)=2.69C+84.23
B(C)=1.99C+85.63
B(C)=1.79C+86.03
B(C)=1.07C+87.47
Answer:
3rd option: B(C)= 1.79C +86.03
Step-by-step explanation:
Total bill
= cost of cans(number of cans) +cost of other groceries
Let the cost of other groceries be G, and the cost of cans be X.
Given that number of cans= C,
Total bill= XC +G
If 2 cans were purchased,
2X+G= 89.61 -----(1)
If 5 cans were purchased,
5X +G= 94.98 -----(2)
(2) -(1):
(5X +G) -(2X +G)= 94.98 -89.61
5X +G -2x -G= 5.37
3X= 5.37
X= 5.37 ÷3 (÷3 on both sides)
X= 1.79
Subst. X= 1.79 into (1):
2(1.79) +G= 89.61
3.58 +G= 89.61
G= 89.61 -3.58 (-3.58 on both sides)
G= 86.03 (simplify)
Total bill
= XC +G
= 1.79C +86.03
Thus, the function is B(C)= 1.79C +86.03.
Answer:
the answer is (C)=1.79C+86.03

Which ordered pairs are solutions to the inequality y−3x<−4? Select each correct answer.
Answer:
Okay so what you need to understand first is that this is a line right?
So, ask yourself if you know how to graph this line.
If you do graph it, and because this line has a < less than sign it means you shade down but it also means that any point directly on the line won't be a solution because the line is dashed!
There can be many solutions to this line, but only in the solution area/shaded region. This in on the lower right side of the diagonal line that is crossing from almost 2 x-axis to -4 y- axis on the line!
If you would've shown me the list of ordered pairs I would've been able to select the correct ones.

Solve the equation. If necessary
[tex] \frac{3}{4}x + 2x = - \frac{1}{4} + \frac{1}{2}x + 5[/tex]
Answer:
Exact form: x=19/9
decimal form: x=2.1r
Mixed number form: x=2 1/9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = [tex]\frac{19}{9}[/tex]
Step-by-step explanation:
First, make all the different parts into fractions with a common denominator, so that you can add and subtract them easily. In this case, the common denominator is four.
Doing this, you get [tex]\frac{3}{4} x + \frac{8}{4} x = -\frac{1}{4} + \frac{2}{4} x + \frac{20}{4}[/tex]
Isolate all the variables to get [tex]\frac{3}{4} x + \frac{8}{4} x - \frac{2}{4} x = -\frac{1}{4} +\frac{20}{4}[/tex]
Then, combine like terms [tex]\frac{9}{4} x = \frac{19}{4}[/tex]
Multiply both sides by 4 to get 9x=19
Divide both sides by 9, and you get [tex]x= \frac{19}{9}[/tex]

If f(x) = 2x – 4 and g(x) = x 2 – 4x, find each value.
Answer:
Step-by-step explanation:
First, solve for each function separately:
F(5)=52+4(5)F(5)=25+20⇒F(5)=45
G(6)=2(6)+2G(6)=12+2⇒G(6)=1
Now, let's add our solutions together:
F(5)+G(6)=45+14=59

The value of the function f (x) is 15/2 when x = -5 and is -73/2 when x = 3. What is the equation of the function?
Answer:
y = -5.5x - 20
Step-by-step explanation:
There are many functions that cross those points.
Assuming you're looking at a straight line.
y = mx + b
15/2 = -5m + b --> 7.5 = -5m + b
-73/2 = 3m + b --> -36.5 = 3m + b
Subtract the first from the second.
-44 = 8m
m = -5.5
Plugging back into the first equation, we get b = -20
Answer:
f(x) = −11/2x − 20

What should we subtract from 50/29 to get 24
Answer:
-22.28
Step-by-step explanation:
Let the number to be subtracted from 50/29 to get 24 to be x
So this can be written as : 50/29 - x =24 ----collect like terms as
50/29 - 24 = x
1.72 -24 = x
-22.28 = x
So to check the answer;
50/29 -{x} = 24
50/29 - {- 22.28} = 24
1.72+ 22.28 = 24 ---correct.

Find the angle measures. Justify your responses.
Given: a||b, m∠3=63
Find: m∠6,m∠7
Answer:
m∠6 = 117°
m∠7 = 63°
Step-by-step explanation:
It's given that a║b and m∠3 = 63°
Since, ∠3 and ∠6 are the consecutive interior angles,
m∠3 + m∠6 = 180°
63° + m∠6 = 180°
m∠6 = 180° - 63°
= 117°
Since, ∠3 and ∠7 are the corresponding angles,
Therefore, ∠3 ≅ ∠7
m∠7 = m∠3 = 63°
