Answer:
The x-intercept is : (22, 0)
Step-by-step explanation:
Given the table
x y
48 30
61 45
74 60
From the table, it is clear that every y value is changing 15 units, and every x is changing 13 units. Hence, it is a straight line.
Hence, we can find the other values of this straight line as well.
so
When the value of y = 15 i.e. (30-15), then the value of x will
be 35 i.e. (48 - 13).
as
y = 30 - 15 = 15, and x = 48 - 13 = 35.
Similarly,
When the value of y = 0 i.e. (15-15), then the value of x will be 22 i.e. (35-13).
as
y = 15-15 = 0, and x = 35 - 13 = 22.
As we know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.
so, as we have checked that when the value of y = 0, then the value of x = 22.
Therefore, the x-intercept is : (22, 0)
Ralph bought some oranges. The weight of the oranges was 2.5 kilograms. How many grams is this? 25,000 g 0.025 g 0.0025 g 2,500 g
Answer:
2,500
Step-by-step explanation:
The weight of the oranges was 2.5 kilograms, the number of grams is, 2500g. So Option D is correct.
What are Units ?To measure and compare various things we use one term which is known as a unit. When all of the measuring units are the same, comparison is simple. Depending on their intended usage, different units can be categorised.
For example, for length measurement we use units like:- meter, centimeter, inch, miles.
Given that,
Ralph bought some oranges.
The weight of the oranges was 2.5 kilograms.
The number of grams = ?
It is known that,
1 kilogram = 1000 gram
so 2.5 kg will be equal to
⇒ 2.5 x 1000
⇒ 2500 g
Hence, the number of grams is 2500g

y = – 2x – 1
y = 1/2 x-1
y = 1/2 x+1
Answer:
y = 2x - 1
General Formulas and Concepts:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope-Intercept Form: y = mx + b

Step 1: Define
Find points on the graph.

Point (-1, -3)
Step 2: Find slope m
Substitute: [tex]m=\frac{-3-1}{-1-1}[/tex]Subtract: [tex]m=\frac{-4}{-2}[/tex]Divide: [tex]m=2[/tex]Step 3: Find y-intercept b
Given: (0, -1) as y-intercept
Step 4: Write linear equation
y = 2x - 1
The equation y = 2x - 1 is the correct representation of the line in slope-intercept form.
The slope-intercept form of a linear equation is given by y = mx + b, where m represents the slope of the line and b represents the y-intercept.
Among the options provided, the equation y = 2x - 1 is already in the slope-intercept form. In this equation, the slope is 2, which means that for every unit increase in x, y increases by 2. The y-intercept is -1, indicating that the line intersects the y-axis at the point (0, -1).
The equations y = -2x - 1, y = 1/2x - 1, and y = 1/2x + 1 are not in slope-intercept form. In the equation y = -2x - 1, the slope is -2 and the y-intercept is -1. In the equation y = 1/2x - 1, the slope is 1/2 and the y-intercept is -1. Lastly, in the equation y = 1/2x + 1, the slope is 1/2 and the y-intercept is 1.
Therefore, the equation y = 2x - 1 is the correct representation of the line in slope-intercept form.

Maria is putting up a shelf on a wall in her closet. The figure below shows triangle ABC, which
represents a bracket that will be used to support the shelf. What is the length of the wall? *
Anwer:
14 cm
Step-by-step explanation:
Let's apply the Phytagorean Theorem [tex]a^{2}+b^{2}=c^{2}[/tex]
Since we only have one side and the hypotenuse:
[tex]a^{2}+24^{2}=28^{2}\\a^{2}+576=784\\a^{2}=784-576\\a^{2}= 208\\[/tex]
[tex]a=\sqrt{208}\\a= 14.42\\a= 14 cm[/tex]
The length of the wall is approximately 14.4 units.
What is Pythagoras' theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Maria is putting up a shelf on a wall in her closet.
The figure below shows triangle ABC, which represents a bracket that will be used to support the shelf.
AC = 24, BC = 28 = hypotenuse, AB = wall
Using the Pythagorean theorem, we can solve for the length of AB (the wall):
AB² = BC² - AC²
AB² = 28² - 24²
AB² = 784 - 576
AB² = 208
AB = sqrt(208)
AB ≈ 14.4
Therefore, the length of the wall is approximately 14.4 units.

How many different ways can you place 4 identical marbles in three jars shown below? Note: Every marble needs to be in one of the jars, but not every jar needs to have a marble in it.
Answer:
3 ways
Step-by-step explanation:
How many different ways can you place 4 identical marbles in three jars shown below? Note: Every marble needs to be in one of the jars, but not every jar needs to have a marble in it.
We solve using combination
n-1 C r-1 = nCr = n!/r! (n - r)!
n = 4 identical marbles
r = 3 jars
Hence:
4 - 1 C 3 - 1 = 3C2
= 3!/2! (3 - 2)!

Answer:
Bosian used the wrong conversion for converting Gallons to Quarts. The correct conversion is: 1 gallon = 4 Quarts and correct solution is: 5 gallon = 20 quarts
Step-by-step explanation:
Bosian Conversion from Gallons to Quarts
He had 5 gallons
He said that 1 gallon = 5 quarts
So, 5 gallons = 5*5 = 25 quarts
Mistake of Bosian:
He used the wrong conversion: i.e, 1 gallon = 5 quarts
The correct conversion is:
1 gallon = 4 quarts
Correct Solution:
1 gallon = 4 quarts
So, 5 gallons = 5*4 = 20 quarts

I was earning $47,000 per year until she received a 7% raise at the start of 2019. What will her new salary be? Write a proportion and show how you solved.
Answer:
$50,290
Step-by-step explanation:
I was earning $47,000 per year until she received a 7% raise at the start of 2019.
Step 1
We find how much 7% raise is
Hence,
7 % of $47,000
= 7/100 × $47,000
= $3290
What will her new salary be?
Her new salary is calculated as:
Last year's salary + 7% raise
= $47,000 + $3290
= $50,290
Her new salary is $50,290
A board 75 cm long is cut into two parts such that one part is 15 cm more than the other. How long is each part?
Answer:
30 cm, and another is 45 cm.
Step-by-step explanation:
First, we need to subtract 15 from 75, giving us 60. Then, we divide 60 by 2, giving us 30, which is the length of one part. We add 15 back to 30, which gives us 45. One part is 30 cm and the other is 45 cm
