1) determine the y-intercept, and
2) use the given slope to come up with another point on the line.
Looking at the graph, you can easily see that the graph crosses the y-axis at (0,2). Thus, the y-intercept is 2.
Now let's determine the slope of this line:
Begin at the point (-4,0) (which happens to be the x-intercept).
Move 4 units from there to the right. How many units UP must you then travel to reach the graph? call this "m."
Then the slope is m/4.
Then the equation of the line is y = mx + b, or
y=(1/2)x + 2 or y = x/2 + 2

4 girls and 4 boys run. Then 2 more children run. The same number of girls and boys run. How many of each run
Answers
If we start out with the same amount of boys and girls at the beginning, then we must add the same number to both groups to maintain that same amount. In this case, since there's already 4 in both groups, you would need to split 2 in half and add the remainder to both groups.
2 ÷ 2 = 1
boys: 4 + 1 = 5
girls: 4 + 1 = 5
So, 5 girls and 5 boys are running.

what is rounding and estimate 253,495 - 48,617=
Answers
Answer:
205000
Step-by-step explanation:
Given : 253,495 - 48,617
To Find : What is rounding and estimate
Solution:
To Estimate a difference by rounding.
1 ) Round each term that will be subtracted
2 )Subtract the rounded numbers
Round off of 253,495 = 253000
Round off of 48,617 = 48000
So, 253000 - 48000 = 205000
Hence The rounding and estimate 253,495 - 48,617= 205000

Write the equation of a line whose slope is -2 and passes through (-1,6). Write the answer in slope-intercept form.
Answers
slope(m) = -2
(-1,6)....x = -1 and y = 6
now we sub and find b, the y int
6 = -2(-1) + b
6 = 2 + b
6 - 2 = b
4 = b
so ur equation is : y = -2x + 4 <==
Start by plugging all those values into the slope intercept equation.
6 = -2*-1 + B
Solve for B.
B = 4
Now, all you have to do is put it back into the equation again, this time not using the (X,Y) we had initially, but just the slope (-2) and our new "B" value (5).
The resulting equation looks like this:
y= -2x + 4
And that's the answer.

The correct option is d. 8 oz. can of juice is most convenient to meet this requirement.
First, let's convert 240 milliliters to ounces because the answer choices are in ounces.
1 milliliter is approximately equal to 0.0338 ounces.
So, 240 milliliters is approximately \( 240 \times 0.0338 \) ounces, which is about 8.112 ounces.
Now, let's examine the options:
a. 5 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.
b. 4 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.
c. 12 oz. can of juice: More than enough juice. It's more than the required 8.112 ounces.
d. 8 oz. can of juice: Exactly the amount needed. It matches the required 8.112 ounces, which is the closest to the calculated amount of 8.112 ounces.
Therefore, the 8 oz. can of juice is the most convenient option to meet the requirement of having 240 milliliters of juice every 2 hours.

A. 55d=t
B. d=55t
C. t/d=55
D. 55/d=t
Plz help I think the answer is D am not sure.
Answers
The correct equation for the distance Tran drove at a constant speed of 55 mph is B. d = 55t.
In this equation:
"d" represents the distance in miles that Tran drove.
"t" represents the time in hours.
So, the distance "d" is equal to Tran's constant speed of 55 mph multiplied by the time "t" in hours, which is why the equation is written as d = 55t.
Option D is not the correct equation because it has the variables and constants in the wrong order.
The correct order is distance (d) on the left side of the equation, followed by the constant speed (55) and then the time (t) on the right side of the equation.

solve the equation by completing the square 5x(x+6)=-50
Answers
5x^2 + 30x = -50
Lets divide every term by 5
x^2 + 6x = -10
To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9
Add that to both sides of the equation
x^2 + 6x + 9 = -1
Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)
(x+3)^2 = -1
Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i
To solve the equation 5x(x+6) = -50 by completing the square, we first isolate the quadratic term and then add the square of half the coefficient of x to both sides of the equation. Taking the square root gives us the solution x = -3 + i and x = -3 - i.
Explanation:
To solve the equation by completing the square, we first need to isolate the quadratic term on one side of the equation. So, let's distribute the 5x to get 5x^2 + 30x = -50. Next, we move the constant term to the other side and divide the equation throughout by the leading coefficient to get x^2 + 6x + 10 = 0.
Now, we can complete the square by adding the square of half the coefficient of x (which is 3) to both sides of the equation. This gives us (x + 3)^2 + 10 - 9 = 0, which simplifies to (x + 3)^2 + 1 = 0.
Taking the square root of both sides, we get x + 3 = ±√(-1), which means x = -3 ± i. Hence, the solution to the equation is x = -3 + i and x = -3 - i.

Answer: 40%
Step-by-step explanation:
Given : Katie is selling lemonade for $1.50 per cup she decides to put them on sale for $0.90 .
i.e. Original price= $1.50 ; Price after discount= $0.90
Then, the Discount amount= Original price-Price after discount
= $1.50- $0.90=$0.60
Now, the percent discount will be :-
[tex]\dfrac{\text{\text{Discount amount}}}{\text{original price}}\times100\\\\=\dfrac{0.60}{1.50}\times100=40\%[/tex]
Hence, the required answer = 40%

A 25-foot streetlight casts a showdown 20feet long.If Melanie is standing at the end of the shadow casted by a 60. -foot tall building,how far is she from the building.
Answers
Heres my working
20% of 25=20 so 20% of 60=48.
Hope this helped ☺️
By setting up a proportion based on the similar triangles created by the streetlight and the building, we can find that Melanie is standing 48 feet away from the building.
To solve the problem of determining how far Melanie is standing from the building using the shadows, we can use similar triangles. We are given a 25-foot streetlight that casts a 20-foot shadow and a 60-foot tall building. The goal is to find the length of the shadow cast by the building, which will tell us how far Melanie is from the building.
By setting up a proportion based on the similar triangles, we have:
Height of the streetlight / Length of streetlight's shadow = Height of the building / Length of the building's shadow.25 feet / 20 feet = 60 feet / x feet.To find the value of x, we cross multiply:25x = 60 * 20.x = (60 * 20) / 25.x = 1200 / 25.x = 48 feet.Therefore, Melanie is standing 48 feet away from the building.

What are 5/6 and 7/9 written with their least common denominator (LCD)?
Answers
The least common denominator of 5/6 and 7/9 is 18. This results in equivalent fractions of 15/18 for 5/6 and 14/18 for 7/9.
Explanation:To find the least common denominator (LCD) of the fractions 5/6 and 7/9, we first find the least common multiple (LCM) of the two denominators, 6 and 9. The LCM of 6 and 9 is 18.
Next, we convert each fraction to an equivalent fraction with the LCD as the new denominator. We multiply the numerator and denominator of 5/6 by 3 to get 15/18. Similarly, we multiply numerator and denominator of 7/9 by 2 to obtain 14/18.
So the fractions 5/6 and 7/9, when written with their LCD, are 15/18 and 14/18, respectively.
