Answer: x= 1 and y =1

Step-by-step explanation:

The given system of equation is :

$5x - 4y = 1-------(1)\\\\2x + 3y = 5----------(2)$

Multiply 2 to equation (1) and 5 to equation (2) , we get

$10x-8y=2-------------(3)$

$10x+15y=25-----------(4)$

Subtracting equation (3) from equation (4), we get

$15y+8y=23\\\\\Rightarrow\ 23y=23\\\\\Rightarrow\ y=1$

Substitute, the value of y in (1), we get

$5x - 4(1)= 1\\\\\Rightarrow\ 5x=1+4=5\\\\\Rightarrow\ x=\dfrac{5}{5}=1$

Hence, the solution of the given system is (x,y) = (1,1)

Which best describe a vector

ANEK [815]

Answer:

Vectors are used to represent physical magnitudes that have an associated address.For example,if we want to represent the displacement of an object,it is not enough to describe only the distance as 10 meters, it is also necessary to describe in which direction the displacement occurred,for example,30°towards the northeast.

Hope this helps:)

Solve for missing variable d=rt, r=57, t=4

____ [38]

D=228

when 2 numbers or variables are next to eachother it means you need to multiply. So in this case r=57 and t=4 and we mulitply. 57 x 4 = 228. So the answer is 228. Hope this helps and have a great day!

a square has the side measurment of s = 2 3 over 2 using the formula 1= s^2 find the area of the square

vitfil [10]

Check the picture below.

$\bf A=s^2\qquad s=2\frac{3}{2}\qquad A=\left( 2\frac{3}{2} \right)^2\implies A=\left( \frac{2\cdot 2+3}{2} \right)^2
\\\\\\
A=\left( \frac{7}{2} \right)^2\implies A=\cfrac{7^2}{2^2}\implies A=\cfrac{49}{4}\implies A=12\frac{1}{4}$

Write an equation of the line that passes through the given point.<br><br> (1,3); y=2x+6

andrew11 [14]

So, you need to know that the slope stays where it is, and that the 6 is not part of the final answer, so get rid of it.
y=2x+b
Now, submit x in for x, and y in for y.
3=2(1)+b
3=2+b
1=b

Put this in for the equation missing the b,
y=2x+1
Now check it; if you put 1 in for x, does y=3?
