39. State the equation for the line described below.
40. State the equation of the line that passes through the points (–7, 5) and (–12, 4).
Picture is attached
Answer:
Step-by-step explanation:
39). y = [tex]-\frac{7}{8}[/tex] x + 3
40). m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
(- 7, 5)
( - 12, 4)
m = ( 4 - 5 ) / ( - 12 + 7) = 1/5
y - 5 = (1/5)(x + 7) ⇒ y = [tex]\frac{1}{5}[/tex] x + 6.4
in which quadrant is the solution to this system of equations? 2x + 5y = 1
3x - 4y = 13
Answer: Quadrant IV
Step-by-step explanation: Pic attached.
I found the x and y using substitution (isolating one variable and plugging it into the other). There was probably an easier way but I couldn't think of it at that moment.
From there, you have the point ( 133/36 , -23/18), or a (+, -).
Find Which quadrant has positive x and negative y.
In this case, this would be Quadrant IV or 4.

1. A spool of ribbon holds 6.75 meters. A craft club buys 21 spools. What is the total cost if the ribbon sells for $2 per meter?
2. A spool of ribbon holds 6.75 meters. If the club uses 76.54 meters to complete a project, how much ribbon will be left
Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:
[tex]T=21(6.75)=141.75\text{ meters}[/tex]
Each meter costs $2. So, the total cost will be:
[tex]141.75(2)=\$ 283.50[/tex]
Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:
[tex]141.75-76.54[/tex]
Subtract:
[tex]=65.21\text{ meters}[/tex]
So, 65.21 meters of ribbon will be left.
Answer:
1. $283.5
2. 11
Step-by-step explanation:
1. 6.75*21 = 141.75
= 141.75 * 2
= 283.5

A recipe for whole wheat pizza crust calls for 1 1/2 cups of all purpose flour. Jeremy has 5 7/4 cups of all purpose flour. If he makes the recipe, how much flour will he have left?
Answer:
Jeremy has 5 1/4 cups of all purpose flour after preparing his recipe.
Step-by-step explanation:
Since the recipe for whole wheat pizza crust calls for 1 1/2 cups of all purpose flour, 1.5 cups of that product is required to create the meal in question.
Now, since Jeremy has 5 7/4 of all purpose flour, it can be stated that he has 6.75 cups of it (7/4 = 1.75).
Therefore, to determine the amount of flour that Jeremy will have left over after preparing the recipe, it is necessary to perform the following calculation:
6.75 - 1.5 = X
5.25 = X
So since 0.25 is equal to 1/4, Jeremy has 5 1/4 cups of all purpose flour after preparing his recipe.
4x≤12= I don't understand
Answer:
x ≤ 3
Step-by-step explanation:
Just divide both sides by 4, the sign stays the same because you're dividing by a positive number
Answer:
its x ≤ 3
Step-by-step explanation:
4x≤12
4x/4 ≤ 12/4 divide both sides by 4
that will give you x≤3.
So, that means x is less than or equal to 3.

Answer:
[tex]y\approx 11.9[/tex]
Step-by-step explanation:
Here, we have the known angle sandwiched between two known sides.
So, we have SAS.
And we want to find the side opposite to the angle.
Therefore, we can use the Law of Cosines:
[tex]c^2=a^2+b^2-2ab\cos(C)\\[/tex]
Again, it is important what we substitute.
a and b are the two side lengths. So, we will substitute 8 for a and 13 for b.
C is our angle. So, substitute 64 for C.
And c is what we’re trying to solve.
Therefore:
[tex]c^2=(8)^2+(13)^2-2(8)(13)\cos(64)[/tex]
Simplify:
[tex]c^2=64+169-208\cos(64)[/tex]
Add:
[tex]c^2=233-208\cos(64)[/tex]
Take the square root of both sides:
[tex]c=\sqrt{233-\cos(64})[/tex]
Use a calculator. So, c is approximately:
[tex]c\approx11.9[/tex]
The c is our y. So, y is approximately 11.9 units.

Answer:$1.25 per bagel
Step-by-step explanation:
5/4=1.25
The cost of each bagels is $1.25.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Teresa went to a bakery to buy bagels.
Teresa paid $5.00 for 4 bagels.
Cost of each bagel = Total cost/Number of bagels
= 5/4
= $1.25
Therefore, the cost of each bagels is $1.25.

Answer:
-1 because when you add both functions thats what you get.
The sum of the functions f(x) and g(x) is -1.
What is a function?
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. A common notation for a function is "f(x)," where x denotes the input value. Example: f(x) = x/2.
What will be the sum of given functions?Add both the functions as,
f(x)+g(x)=-x+4+x-5
Collect the like terms of right side,
f(x)+g(x)=-1
Therefore, the sum of the function f(x) and g(x) is -1.
