What is linear equations?When graphed, a linear equation always produces a straight line because it is an algebraic equation with each term having an exponent of 1. It is referred to as a "linear equation" for this reason.
One-variable linear equations and two-variable linear equations exist.
Given
items produced by first plant is
8x + 15
let x = 1
8 x1 + 15
23
items produced by second plant
5x - 2
let x = 1
5 x 1 - 2 = 3
the difference in both plant is
23 - 3 = 20
Hence first plant produce 20 more items than second plant.

Answer:
Step-by-step explanation:
(4a - 3)/(3b + 1) = 39/(a + 1) You are not going to get a numerical answer for this. Cross multiply
(4a - 3)(a + 1) = 39(3b + 1)
4a^2 + a - 3 = 117b + 39
4a^2 + a - 42 = 117b
b = [tex]\frac{a^2 +a - 42}{117}[/tex]
Answer:
b = 3
Step-by-step explanation:
I think that the relations are the following
[tex]\frac{QP}{XY}=\frac{RS}{VZ}=\frac{PT}{XW}\\\\\frac{39}{13}=\frac{4a-3}{a+1}=\frac{5a+6b}{5b+1}\\\\3=\frac{4a+3}{a-1}=\frac{5a+6b}{5b+1}[/tex]
so we first solve for a and then for b
[tex]3=\frac{4a-3}{a+1}\\\\3(a+1)=4a-3\\\\3a+3=4a-3\\\\4a-3a=3+3\\\\a=6[/tex]
and now for b
[tex]3=\frac{5a+6b}{5b+1}\\\\3(5b+1)=5a+6b\\\\15b+3=5a+6b\\\\15b=5a+6b-3\\\\15b-6b=5a-3\\\\9b=5a-3\\\\b=\frac{5a-3}{9}\\\\b=\frac{5(6)-3}{9}\\\\b=\frac{30-3}{9}\\\\b=\frac{27}{9}\\\\b=3[/tex]

This question applies to ALL the photos: Is there enough information to prove that the triangles are congruent? If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement. If no, justify your answer.
Answer:
There is enough evidence to prove they are congruent. AAS would be what's used in this case.
Step-by-step explanation:
(< = angle)
<B = <Z, <A = <Y, line AC and line XY are equal.
Edit: So it appears that each of the photos are congruent. They have enough labels on them to tell you that their last unidentified angle would have to be congruent as well, meaning that each picture is congruent.

(CO 4) Supplier claims that they are 95% confident that their products will be in the interval of 20.45 to 21.05. You take samples and find that the 95% confidence interval of what they are sending is 20.48 to 21.02. What conclusion can be made
Answer:
The supplier is less accurate than they have claimed
Step-by-step explanation:
Given that:
95% confidence interval of supplier's claim :
(20.45, 21.05)
Mean = (20.45 + 21.05) /2 = 41.5 / 2 = 20.75
Error margin = (upper bound - mean) = 21.05 - 20.75 = 0.30
95% confidence interval of your sample :
(20.48, 21.02)
Mean : (20.48 + 21.02) /2 = 41.05 / 2 = 20.75
Error margin = (upper bound - mean) = 21.02 - 20.75 = 0.27
0.3 > 0.27
From the calculations made, the mean are the same, but the error margin of supplier is higher, thus it could be concluded that the supplier is less accurate than they have claimed
A worker uses 750 inches of steel wire to make 300 springs of the same size. At this rate how many inches of steel wire are needed to make 1 spring?
2.5 inches steel wire
We can use an equation to find the answer. 750/300 = 2.5
Answer:
2.5 inches of steel wire are needed to make one spring.
Step-by-step explanation:
In order to answer this, we can set up a proportion (setting two fractions equal to each other) to solve for how many inches of steel wire are needed to make one spring.
We are given a ratio: 750 inches of steel wire are required to make 300 springs. Therefore, this is represented as:
[tex]\bullet \ \ \ \text{750 inches of steel wire : 300 springs}[/tex]
This can be rewritten in fraction form:
[tex]\displaystyle \bullet \ \ \ \frac{\text{750 inches of steel wire}}{\text{300 springs}}[/tex]
Therefore, we have our first proportion.
We want to make one spring, so we need to find how much steel is required to make one spring. Therefore, for our second fraction, the inches of steel wire is unknown. We can define this as x.
[tex]\bullet \ \ \ \text{x inches of steel wire}[/tex]
Finally, our ratio can be written in the same manner as the previous ratio:
[tex]\bullet \ \ \ \text{x inches of steel wire : 1 spring}[/tex]
This can be rewritten in fraction form:
[tex]\displaystyle \bullet \ \ \ \frac{\text{x inches of steel wire}}{\text{1 spring}}[/tex]
Now, we need to set up our proportion. We do this by setting our two ratios equal to each other.
[tex]\displaystyle \bullet \ \ \ \frac{\text{750 inches of steel wire}}{\text{300 springs}} = \frac{\text{x inches of steel wire}}{\text{1 spring}}[/tex]
To solve a proportion, we need to cross multiply. We can flip our fractions and solve for the reciprocal since there is not really a way to represent cross-multiplication.
[tex]\displaystyle \bullet \ \ \ \frac{\text{750 inches of steel wire}}{\text{300 springs}} = \frac{\text{1 spring}}{\text{x inches of steel}}[/tex]
First, we can drop our labels/units.
[tex]\displaystyle \bullet \ \ \ \frac{750}{300} = \frac{1}{\text{x}}[/tex]
Then, we can multiply across.
[tex]\displaystyle \bullet \ \ \ 750 = 300x[/tex]
Finally, we can solve for x.
[tex]\displaystyle 750 = 300x\\\\\frac{750}{300}=\frac{300x}{300}\\\\2.5 = x\\\\x = 2.5[/tex]
Therefore, to make one spring, exactly 2.5 inches of steel wire are needed.

An automobile manufacturer claims that its car has a 37.9 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this car since it is believed that the car has an incorrect manufacturer's MPG rating. After testing 140 cars, they found a mean MPG of 38.2. Assume the standard deviation is known to be 1.2. A level of significance of 0.01 will be used. Find the value of the test statistic. Round your answer to 2 decimal places
Answer:
2.958
Step-by-step explanation:
Sample mean (x) = 38.2 MPG
Population mean (μ) = 37.9 MPG
Sample size (n) = 140
Standard deviation (σ) = 1.2
The test statistic (Tstat) can be obtained thus :
(x - μ) / σ/sqrt(n)
Tstat = (38.2 - 37.9) / 1.2/sqrt(140)
Tstat = 0.3 / 0.1014185
Tstat = 2.9580401
Test statistic = 2.958

Ram gained 25 percent by selling a second hand motorcycle for Rs. 45000. At
price did Ram buy that motorcycle?
Answer:
Ram bought that motorcycle for Rs. 36000
Step-by-step explanation:
Given that:
Amount gained = 25%
Selling price of motorcycle = Rs. 45000
As 100% will be the original price, then 25% will be added into it.
125% will be the new percentage.
Let,
x be the original price of motorcycle.
125% of x = 45000
[tex]\frac{125}{100}x=45000[/tex]
1.25x=45000
Dividing both sides by 1.25
[tex]\frac{1.25x}{1.25}=\frac{45000}{1.25}\\[/tex]
x=36000
Hence,
Ram bought that motorcycle for Rs. 36000
