What is the apparent solution to the system of equations? y=1/2x+2 y=2x−1

1 answer:

8 0

X = 2
y = 3

You can simply set these two equal to each other and solve for x. Then plug in to find y.

For this specific problem, this would be the solution: = 0.7(133) + 0.8(133) - 2(0.4[133]) 
= 93 + 106 - 2(53) 
= 199 - 106 
= 93

This means 93 students passed in both the subjects. I am hoping that this answer has satisfied your query about and it will be able to help you.

$x^3 + x^2 - 20x=0\\
x(x^2+x-20)=0\\
x(x^2+5x-4x-20)=0\\
x(x(x+5)-4(x+5))=0\\
x(x-4)(x+5)=0\\
x=0 \vee x=4 \vee x=-5$

Answer:

c = 60.65 cm

Step-by-step explanation:

Given that,

The two sides of a triangle are 33 cm and 37 cm.

The angle between these two sides is 120°.

We need to find the length of the third side of the triangle. Let c is the third side. Using cosine rule,

$c^2=a^2+b^2-2ab\cos C$

a = 33 cm, b = 37 cm and C is 120°

So,

$c^2=(33)^2+(37)^2-2\times 33\times 37\cos (120)\\\\c=60.65\ cm$

So, the length of the third side of the triangle is 60.65 cm.
