Write the equation of the line that passes through the points (1, 7) and (5, 15) using function notation.
Answer:
use the formula for a line through two points
[tex]y - y_{1} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \times (x - x_{1})[/tex]
plug in the given points:
[tex]y - 7 = \frac{15 - 7}{5 - 1} \times (x - 1)[/tex]
[tex]y = \frac{8}{4} \times (x - 1) + 7[/tex]
[tex]y = 2 \times (x - 1) + 7 \\ y = 2x - 2 + 7 \\ y = 2x + 5[/tex]

The record low temperature in Pittsburgh, PA is -22°F. The record high is 103°F. What is the difference in the record high and the record low temperatures?
Answer:
The difference in the record high and the record low temperatures is 125°F
Step-by-step explanation:
Given a quantity T that varies in time, say T1 and T2, being T1 the initial value and T2 the final value.
The change or difference between the final and the initial values is:
T=T2-T1
The record low temperature in Pittsburgh, PA is T1=-22°F while its record high is T2=103°F
The difference is:
T=103°F - (-22°F)
Note both negative signs multiply to produce a positive sign, and a sum instead of a subtraction:
T=103°F + 22°F = 125°F
The difference in the record high and the record low temperatures is 125°F

Step-by-step explanation:
You have to use the KEEP CHANGE CHANGE method. When you do this you end up with 4/7*5/1 which equals 20/7 and you then change that into a mixed number and you have your answer!
HOPE THIS HELPS!
Answer:
The answer is 2 6/7
Step-by-step explanation:
First, you set up the problem.
[tex]\frac{4}{7} / \frac{1}{5}[/tex]
Next, you change the division sign into multiplication
[tex]\frac{4}{7} x \frac{1}{5}[/tex]
Then you flip the 1/5
[tex]\frac{4}{7} x \frac{5}{1} \\[/tex]
Afterward, you multiply fractions straight across.
[tex]\frac{4}{7} x \frac{5}{1} =\frac{20}{7}[/tex]
Finally, you will simplify your answer into a mixed number.
[tex]\frac{20}{7} = 2 6/7[/tex]

How do you solve 5x + 7 = 2x + 1
Answer:
x = -2
Step-by-step explanation:
5x + 7 = 2x + 1
subtract both sides by 2x
3x + 7 = 1
subtract both side by 7
3x = -6
divide both sides by 3
x = -2
30 g of pineapple are added to drink the drink rises 5 ml what is the density of the pineapple
Answer:
6g/mL
Step-by-step explanation:
Given parameters:
Mass of pineapple = 30g
Volume of rise = 5mL
Unknown:
Density of pineapple = ?
Solution:
Density of a substance is the mass per unit volume. Mathematically, it is expressed as;
Density = [tex]\frac{mass}{volume}[/tex]
The volume is the rise in the pineapple drink.
Insert the parameters and solve;
Density = [tex]\frac{30}{5}[/tex]
Density = 6g/mL
6. Which of the following is true about the
graph of the equation y = -5x + 10?
A. The graph would increase from left to right.
B. The graph would pass through the origin.
C. The graph would have a positive y-intercept.
Answer:
C
Step-by-step explanation:
The graph would have a positive y-intercept
The y-intercept is when x = 0
To find the y-intercept, plug in 0 for x
y = -5(0) + 10
y = 0 + 10
y = 10
10 is a positive number
Y-intercept is positive

Which value of x makes the equation true?
0
-5.3
O - 4.1
O 4.1
O 5.3
Answer:
5.3
Step-by-step explanation:
1.8x = 9.4
x = 5.3
The value of x that makes the equation true is 5.3, the correct option is D.
What is an Equation?An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
The equation is,
0.3x + 5. 14 = 2.1x - 4.4
The equation is made of two expressions,
The expression 1 is : 0.3x + 5. 14
The expression 2 is : 2.1x - 4.4
The value of x that makes the equation true has to be determined.
0.3x + 5. 14 = 2.1x - 4.4
Grouping the like terms on one side.
5.14 +4.4 = 2.1x -0.3x
Solving the variables and constants
9.54 = 1.8 x
Dividing 1.8 on both sides of the equation.
x = 9.54 /1.8
x = 5.3
The value of x at which the equation is true is 5.3.

Write the values of the 9s in 990.250. How are the values related?
Answer:
Leftmost 9: 900
9 between 9 and 0: 90
9 on left is worth 10 times 9 on right.
Step-by-step explanation:
990.250
The 9 at the left is in the hundreds place, so it represents 9 hundreds, so its value is 900.
The 9 between the 9 and the 0 is in the tens place, so it represents 9 tens, and its value is 90.
Since the places are right next to each other, the 9 on the left is worth 10 times the 9 on the right. Sure enough, 900 is 10 times 90.
A sample of 87 glass sheets are measured for thickness. They have a sample mean of 4.20 mm and a sample standard deviation of 0.10 mm. What is the level of the confidence interval (4.185, 4.215)?
Answer:
83.85%
Step-by-step explanation:
The formula for confidence interval
= Mean ±( z × Standard deviation/√n)
Confidence Interval = Mean ± Margin of Error
Mean = 4.20mm
n = 87
Standard deviation = 0.10mm
z = ????
Hence:
Confidence Interval = Mean ± Margin of Error
Step 1
We find the Margin of Error
(4.185, 4.215) = 4.20 ± Margin of Error
4.20 - 4.185 = 0.015
4.215 - 4.20 = 0.015
Hence, Margin of Error = ± 0.015
Step 2
We find the z score
Margin of Error = z × Standard deviation/√n
±0.015 = z × 0.10/√87
± 0.015 = 0.0107211253z
z = ±0.015/0.0107211253
z = 1.39910686428
z score ≈ 1.4
Step 3
We find the confidence interval that corresponds to 1.4
Using the z table to find the Probability
P(z = 1.4) = 83.85%
Therefore, the level of the confidence interval (4.185, 4.215) is 83.85%
Answer:
[4.1mm to 4.3mm]
Step-by-step explanation:
Sample size = 87 glass sheets
Sample mean = 4.2mm
Sample standard deviation = 0.1mm
Confidence interval or level = the range from lower limit of sample mean to upper limit of sample mean
[4.2 - 0.1] to [4.2 + 0.1] = [4.1mm to 4.3mm]
A large ladder leans against a house with the base of the ladder 5.8 horizontal feet from
the base of the house. If the ladder has a slope of 3.3 feet per foot, at what height does the top of the ladder meet the house? (Round your answer to two decimal places.)
=_______ft
Answer:
At 19.14 feet the top of the ladder meet the house.
Step-by-step explanation:
It is given that,
A large ladder leans against a house with the base of the ladder 5.8 horizontal feet from the base of the house.
Slope of the ladder, m = 3.3 feet/foot
We need to find at what height does the top of the ladder meet the house. Let it is h.
Base, b = 5.8 feet
It will form a right angle triangle
Slope=h/base
h = slope × base
h = 3.3 × 5.8
h = 19.14 feet
So, at 19.14 feet the top of the ladder meet the house.

The complete table is given as follows -
Time (in hours) Snow (in inches)
0 1

[x] [2x]
The equation that shows the amount of snow that has fallen after [x] hours can be written as y = 2x
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is that snow Is falling steadily such that after 2 hours, 4 inches of snow has fallen.
In 2 hours → 4 inches of snow has fallen.
Then, in 1 hour → (4/2) → 2 inches of snow has fallen.
So, in 6.5 hours → 2 x 6.5 → 13 inches
Hence, in x hours → 2x inches
The complete table is shown below
Time (in hours) Snow (in inches)
0 1

The equation that shows the amount of snow that has fallen after [x] hours can be written as -

The equation that shows the amount of snow that has fallen after [x] hours can be written as y = 2x
