Find the slope of the line with the equation 12x - 8y + 7 = 9.
-3/2
312
2/3
Final answer:
The slope of the line represented by the equation 12x - 8y + 7 = 9 is 3/2. To find this, the equation was rearranged into slope-intercept form, revealing the slope as the coefficient of x.
Explanation:
To find the slope of the line with the given equation 12x - 8y + 7 = 9, you first need to rearrange the equation into slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept.
First, subtract 12x from both sides of the equation to isolate terms with y on one side:
-8y = -12x + 2
Next, divide each term by -8 to solve for y:
y = (12/8)x - 2/8
Simplify the fractions:
y = (3/2)x - 1/4
Now the equation is in slope-intercept form, and you can see that the slope m is 3/2 or 1.5. Therefore, the slope of the line is 3/2.
Mrs. Fronkos class for evry 6 boys there are 8 girls. Write the ratio of boys to girls in simplest form
Final answer:
The ratio of boys to girls in Mrs. Fronko's class in simplest form is 3:4, obtained by dividing both sides of the given ratio, 6:8, by the greatest common divisor, which is 2.
Explanation:
To find the ratio of boys to girls in Mrs. Fronko's class in its simplest form, we will start with the ratio given, which is 6 boys for every 8 girls. This can be written as 6:8. To simplify ratios, we divide both sides of the ratio by the greatest common divisor. In this case, the greatest common divisor of 6 and 8 is 2. Therefore, we divide both numbers by 2 to find the simplest form of the ratio.
6 ÷ 2 = 3 and 8 ÷ 2 = 4.
After dividing both numbers by 2, the ratio becomes 3:4. This indicates that for every 3 boys, there are 4 girls in Mrs. Fronko's class, and this is the simplest form of the ratio.
a salesman receives a salary rs 1000 per month and 10%commission on sales in excess of rs 5000.what is the amount of sales if he earns rs.2000. in a particular month
Answer:
Amount of sales = rs 10,000.
Step-by-step explanation:
He earns 2000 - 1000 = rs 1000 from sales.
This equals 10% ( = 0.10 as a fraction) of his sales so his sales must have been 1000 / 0.10
= rs 10,000.

Solve −2x2 − 16x − 44 = 0.
The solution to the quadratic equation -2x² - 16x - 44 = 0 are [tex]x = -4 -4\sqrt{6}i \ and \ x = -4 +4\sqrt{6}i[/tex]
Given the quadratic equation in the question:
-2x² - 16x - 44 = 0
To solve the quadratic equation -2x² - 16x - 44 = 0, we use the quadratic formula:
[tex]x = \frac{-b\±\sqrt{b^2 - 4ac} }{2a}[/tex]
From the equation:
a = -2, b = 16, c = -44
Plug these values into the above:
[tex]x = \frac{-b\±\sqrt{b^2 - 4ac} }{2a} \\\\x = \frac{-(-16)\±\sqrt{(-16)^2 - 4(-2)(-44)} }{2(-2)} \\\\x = \frac{16\±\sqrt{256 - 352} }{-4} \\\\x = \frac{16\±\sqrt{-96} }{-4} \\\\x = \frac{16\±4\sqrt{6}i }{-4} \\\\x = -4 \±4\sqrt{6}i\\\\x = -4 -4\sqrt{6}i \ or \ x = -4 +4\sqrt{6}i[/tex]
Therefore, the values of x are [tex]x = -4 -4\sqrt{6}i \ and \ x = -4 +4\sqrt{6}i[/tex]
Y is inversely proportional to x. If y= 400 when x =2 find y when x= 200
Answer: 4
Step-by-step explanation:
Inversely proportional means xy = k, where k is the constant of proportionality
First, find k when x = 2 and y = 400 ----> 2(400) = k --> 800 = k
Then, find y when x = 200 (knowing that k = 800)
200y = 800

The equation 3w + 4j = 39 is used to determine the number of water bottles w and the number of juice bottles j that can be bought for $39. If you purchase 6 bottles of juice, how many bottles of water can you buy?
Juice bottles are J, replace j with 6 in the equation and solve for w:
3w + 4(6) = 39
3w + 24 =39
Subtract 24 from both sides:
3w = 15
Divide both sides by 3:
w = 15/3
w = 5
You can buy 5 water bottles.
Answer:
5
Step-by-step explanation:
The number of water bottles [tex]= w[/tex]
The number of juice bottles [tex]= j[/tex]
We have, [tex]3w + 4j = 39[/tex]
When we purchase 6 bottles of juice, [tex]j = 6[/tex]
So,
[tex]3w + 4j = 39[/tex]
[tex]3w + 4 \times 6 = 39[/tex]
[tex]3w + 24 = 39[/tex]
[tex]3w = 39 - 24[/tex]
[tex]3w = 15[/tex]
[tex]w = \frac{15}{3}[/tex]
[tex]w = 5[/tex]
Therefore, we can buy 5 bottles of water.

what is the answer to number 16
Answer:
b ≈ 13.80 in
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for b
tan17.71° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{AC}{43.21}[/tex]
Multiply both sides by 43.21
43.21 × tan17.71° = AC, hence
AC = b ≈ 13.80 ( to 2 dec. places )

Using the appropriate constant of proportionality, provide the value in the table that makes the quantities proportional to one another. Answer format: 8/9 *
Answer:
3
Step-by-step explanation:
If you look closely every X is changing by 3 so 3·y=x
Answer:
The value in the table that makes the quantities proportional to one another is y = 3
Step-by-step explanation:
Two quantities x and y are proportional one to another if they can be expressed as
y = kx
where k is the constant of proportionality. We can find k using an specific point. Take the first one
y = kx
k= y/x with (3.1 )
k= 1/3
So
y =1/3x for this case
If the two quantities are proportional, this rule must be true for any point (x,y) . Lets prove it
Point 2 (6,2)
2 =1/3*(6)
2= 2 True
Point 4 (12,4)
4 =1/3*(12)
4= 4 True
So to accomplish the rule in point 3, and finally in all table we must have that
y =1/3x is true for Point 3 (9,y) Then
y = 1/3 (9) = 9/3 = 3
y= 3
Y must be 3
A town has accumulated 3 inches of snow, and the snow depth is increasing by 6 inches every hour. A nearby town has accumulated 6 inches, and the depth is increasing by 3 inches every hour. In about how many hours will the snowfall of the towns be equal?
Answer:
1 hour
Step-by-step explanation:
set town one equation to 3 + 6x and town two equation to 6+3x
set these two equations equal to each other and solve for x
3 + 6x = 6 + 3x
3x = 3
x = 1
