When using the substitution method to solve the system of equations,
what is the result of the first step?
y = 2x + 4
2x + 3y = 8
Answers
Answer:
B
Step-by-step explanation:
This is due to the fact that the first equation is saying it is equal to y so you replace the y variable with the equation
Answer:
since y=2x+4 just substitute y with 2x+4
2x + 3(2x+4) = 8
so the answer is B

A rectangle has a length that is three times the width . The perimeter of the rectangle is 40 feet.what is the area of the rectangle
Answers
Answer:
The area is 15 feet
Step-by-step explanation:
So you are going to need two different equations-
l = w(3)
2l + 2w = 40
Insert the first equation into the second-
2(3w) + 2w = 40
Simplify this equation-
6w + 2w = 40
8w = 40
Divide both sides by 5
w = 5
Solve first equation
l = 5(3)
l = 15
Then find the area-
5 x 15 = 75

50 = delivery cost
250 = the money you have
B.) 400 + 15n = 505
15n = amount of money you deposite per week, n is # of week
400 = some money in account after n week passed
505 = initial money in bank

The answers will consist of algebraic expressions containing the parameter k.
What positive value of k will result in exactly one real root?
K = ?
Answers
Answer:
The positive value of [tex]k[/tex] will result in exactly one real root is approximately 0.028.
Step-by-step explanation:
Let [tex]h(t) = 19321\cdot k^{2}\cdot t^{2}-69\cdot t +80[/tex], roots are those values of [tex]t[/tex] so that [tex]h(t) = 0[/tex]. That is:
[tex]19321\cdot k^{2}\cdot t^{2}-69\cdot t + 80=0[/tex] (1)
Roots are determined analytically by the Quadratic Formula:
[tex]t = \frac{69\pm \sqrt{4761-6182720\cdot k^{2} }}{38642}[/tex]
[tex]t = \frac{69}{38642} \pm \sqrt{\frac{4761}{1493204164}-\frac{80\cdot k^{2}}{19321} }[/tex]
The smaller root is [tex]t = \frac{69}{38642} - \sqrt{\frac{4761}{1493204164}-\frac{80\cdot k^{2}}{19321} }[/tex], and the larger root is [tex]t = \frac{69}{38642} + \sqrt{\frac{4761}{1493204164}-\frac{80\cdot k^{2}}{19321} }[/tex].
[tex]h(t) = 19321\cdot k^{2}\cdot t^{2}-69\cdot t +80[/tex] has one real root when [tex]\frac{4761}{1493204164}-\frac{80\cdot k^{2}}{19321} = 0[/tex]. Then, we solve the discriminant for [tex]k[/tex]:
[tex]\frac{80\cdot k^{2}}{19321} = \frac{4761}{1493204164}[/tex]
[tex]k \approx \pm 0.028[/tex]
The positive value of [tex]k[/tex] will result in exactly one real root is approximately 0.028.

Answer:
EF = 7
Step-by-step explanation:
the two triangles shown are congruent triangles
we know this because they share the line FD
and DE and DG are both 5
so the length two sides are definitely congruent, this means that the third side will also be congruent
the third side would be FG and EF
FG is 7 so then EF is 7
Answer:
EF is 7
Step-by-step explanation:
Key skills needed: Triangle Congruence
1) We need to find out The length of EF
2) To find this, let's use Congruence of Two Triangles
The triangles that we can prove congruent are Δ DFG and Δ DFE
3) Both share the side DF, so we have one side
Both have a right angle, < FDG is a right angle, and < FDE would also be right angle (you can prove this as ---> < FDE is supplementary to a right angle, and therefore it would also be a right angle)
Both share a congruent set of sides (GD and DE both are 5)
4) With the 3 things above we can say --> Δ DFG ≅ Δ DFE with SAS (side-angle-side)
5) This means that corresponding parts would be congruent.
FG ≅ EF. This means EF would be the same length as FG. Since FG is 7, then EF would be 7.

A travel agent calculates the cost of a trip to Paris using this formula C = p(t + 30).
C is the total cost in pounds
p is the number of people
t is the cost of the trip per person
Use this formula to calculate the total cost if p = 2 and t = 245.
Answers
Answer:
C=550 pounds
Step-by-step explanation:
Given the formula: C=p(t+30)
and with p=2 and t=245 known.
We can plug our values of p and t into our formula. Once we do this, the only unsolved variable will be C.
C=2(245+30)
Add 245+30 first because they are in parentheses and we must abide by the order of operations.
C=2(275)
Now we just multiply 2(275) because this is all that's left in the formula.
C= 2*275 = 550
We now know that C=550 when p=2 and t=245, but we need to apply units to finalize the answer. We are told that C represents the total cost in "POUNDS", so pounds is our units for variable C.
Our final answer is...
C=550 pounds
