Please help me find X and Y! Thank you :)

Mathematics
1 answer:
shepuryov [24]3 years ago

Answer:

The value of x is -29 and the value of y is -26

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding angles and its corresponding sides are congruent

so

The length of the corresponding sides must be equal

-2x+2y=6 ----> equation A

-7x+8y=-5 ----> equation B

Note

The length of one side of the triangle equal to -5 is not logical, however we will continue with the resolution of the problem for didactic purposes.

Solve the system by graphing

Remember that

the solution of the system of equations by graphing is the intersection point both graphs

using a graphing tool

The solution is the point (-29,-26)

see the attached figure

therefore

The value of x is -29 and the value of y is -26

At Tech High there are three math teachers, Mary, Tom, and Alex. All students at Tech High take math, with 21% taking class with
galben [10]

Answer:

The probability that a Tech High student fails math is 0.1006

Step-by-step explanation:

21% students are taking class with Mary.

Every year 4% of Mary’s students fail,

15% students are taking class with Tom

Every year 6% of Tom’s students fail.

64% students are taking class with Alex

Every year 13% of Alex's students fail.

Now we are supposed to find the probability that a Tech High student fails math.

P(\text{Tech High student fails math}) = P(\text{taking class with Mary})\times P(\text{Mary students fail})+P(\text{taking class with Tom}) \times P(\text{Tom students fail})+P(\text{taking class with Alex}) \times P(\text{Alex student fail})

P(\text{Tech High student fails math}) = 0.21 \times 0.04+0.15 \times 0.06+0.64 \times 0.13

P(\text{Tech High student fails math}) =0.1006

Hence the probability that a Tech High student fails math is 0.1006

Which of the following is equivalent to the equation 4x+7y=z?
shtirl [24]

Answer:

x = 1.75y + 0.25z

Step-by-step explanation:

Simplifying

4x + -7y = z

Solving

4x + -7y = z

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

4x + -7y + 7y = 7y + z

Combine like terms: -7y + 7y = 0

4x + 0 = 7y + z

4x = 7y + z

Divide each side by '4'.

x = 1.75y + 0.25z

Simplifying

x = 1.75y + 0.25z

F is inversely proportional to d 2 . When F = 3 , d = 4 Work out F when d = 2
Natalka [10]

Answer:

F = 6

Step-by-step explanation:

find the constant of variation (k) first by using this formula:

f = k/d

plug in given info to find k:  3 = k/4 so k = 12

use 12 to find F:  F = 12/2
