Let's solve your system by substitution.

x+y=8;x−y=4

Step: Solvex+y=8for x:

x+y=8

x+y+−y=8+−y(Add -y to both sides)

x=−y+8

Step: Substitute−y+8forxinx−y=4:

x−y=4

−y+8−y=4

−2y+8=4(Simplify both sides of the equation)

−2y+8+−8=4+−8(Add -8 to both sides)

−2y=−4

−2y/−2=−4/−2 (Divide both sides by -2)

y=2

Step: Substitute2foryinx=−y+8:

x=−y+8

x=−2+8

x=6(Simplify both sides of the equation)

Answer:

x=6 and y=2

What is the product?<br> -9x(5-2x)<br> 
abruzzese [7]

Answer:

The product would be -27x.

Step-by-step explanation:

First you use the distributive property to distribute the -9x to the 5 and the -2x. Then you would get -45x+18x. 18x because when you multiply a negative and a negative you get a positive. Then, you add those two and you should get -27x.

Given the diagram below, what is cos(45")?<br> 45° 6 <br> A. √2<br> B. 6/√2<br> C. 1/√2<br> D. 3√2
Gnesinka [82]
C. 1/root2

Based on the information, the hypotenuse will be 6root2 because it is a 45, 45, 90 triangle. The two legs will be 6. Using SOH CAH TOA, we know that for cosine, it will be adjacent/hypotenuse. The adjacent side is 6 and the hypotenuse is 6root2. The result will be (6)/(6root2). After simplifying, we get
1/root2.
