Find the equation of the line between the points (10, – 5) and ( - 2,0).
Answer (assuming it can be in slope-intercept form):
[tex]y = -\frac{5}{12} x-\frac{5}{6}[/tex]
Step-by-step explanation:
1) First, find the slope of the line between the two points by using the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:
[tex]m = \frac{(0)-(-5)}{(-2)-(10)} \\m = \frac{0+5}{-2-10} \\m=\frac{5}{-12}[/tex]
Thus, the slope of the line is [tex]-\frac{5}{12}[/tex].
2) Next, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{5}{12}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, it will equal the same thing) and substitute its x and y values into the formula as well. (I chose (-2,0), as seen below.) Then, isolate y and expand the right side in the resulting equation to find the equation of the line in slope-intercept form:
[tex]y-(0)=-\frac{5}{12} (x-(-2))\\y-0 = -\frac{5}{12} (x+2)\\y = -\frac{5}{12} x-\frac{5}{6}[/tex]

What is the degree measure of

D
Answer:
34
Step-by-step explanation:
A triangle always has a sum of 180 degrees
First, let us find the right angle
180-149=31
Now find v
180=31+115+x
180-146=x
x=34
Find the value of x.
Answer:
66
Step-by-step explanation:
subtract each external angle by 180 to find the interior angle.
Since you know that all of the interior angles add up to 540 because 180(n-2)
with n is how many sides in the polygon
so 180(5-2)=540
now take each value and subtract it by 180
180-(45)=135
180-(40)=140
180-(x)=180-x
180-(77)=103
180-(2x)=180-2x
135+140+180-x+103+180-2x=540
738-3x=540
x=66

O 55.5 miles
O 41.7 miles
O 63.8 miles
Answer:

Step-by-step explanation:
17² + b² = 23²
289 + b² = 529
b² = 240
b = 15.491 ≈ 15.5
17 + 23 + 15.5 = 55.5
You can also simply notice B is the only answer with a .5 decimal and thus don't have to add.

You want to sell lemonade by the park. Different brands of lemonade have different formulas. You want to sell the lemonade that tastes the most “lemony.” You use 4 cups of lemon concentrate and 6 cups of water.
What fraction of the TOTAL mixture is lemon concentrate? What percentage is this?
Answer:
4/10
Step-by-step explanation:
you add the amount of cups of concentrated lemon plus the amount of water and it is 10. and then it asks for the faction of lemon concentrate out of 10. so it would be 4/10

The price of a book, which regularly sells for $24, was marked down by 25%. A coupon reduced the price by another 10%. What was the final selling price?
Answer:
$16.20
Step-by-step explanation:
24.00 × 25%= 6.00
24.00 - 6.00 = 18.00
18.00 × 10%=1.80
18.00 - 1.80 = 16.20
A percentage is a way to describe a part of a whole. The final cost of the book will be $16.2.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given the cost of the book is $24. Therefore, the cost of the book after a 25% discount is,
Cost of book after discount = $24×(100%-25%) = $18
Now, the cost after the 10% counpon will be,
Cost after the 10% counpon = $18×(100%-10%) = $16.2
Hence, the final cost of the book will be $16.2.

Steven warms a cup of a coffee to a temperature of 195°F and then leaves it to cool in a room that is 75°F. This equation represents the
temperature, T, of the coffee in the cup after x minutes.
T = 75 + 120e-0.051
After how many minutes will the temperature of the coffee be approximately 141°F?
Answer:
12 minutes
Step-by-step explanation:
First substitute 141°F for T in the given equation.
Then isolate the exponential term.
Now rewrite the equation as a natural log, and solve for x.
After 12 minutes will the temperature of the coffee be approximately 141°F.
What is temperature?Temperature is the degree of hotness or coldness expressed in terms of any of numerous scales, such as Fahrenheit and Celsius. Temperature suggests the route wherein heat strength will spontaneously flow—i.e., from a warmer body (one at a better temperature) to a less warm frame (one at a lower temperature).
diploma measures of temperature are typically expressed with the ° temperature scale: The sample became heated to 80 °C.
Substitute the 141°F in the equation
⇒T = 75 + 120e-0.051
⇒ 141 = 75 + 120x - 0.051
⇒ 120x = 141 -75 + 0.051
⇒120x = 66.051
