Answer:
The solution is (2, -2)
Step-by-step explanation:
In order to solve this, multiply the second equation by -5 and then add through.
5x - 4y = 18
-5x - 15y = 20
------------------
-19y = 38
y = -2
Now that we have the value of y, we can solve for x.
x + 3y = -4
x + 3(-2) = -4
x - 6 = -4
x = 2
Answer:
C
Step-by-step explanation:
This is because using the formula of area for shapes, you get this equation
A=2(wl+hl+hw)=2·(4·6+4·6+4·4)=128

Answer:
<h2>9</h2>
Step-by-step explanation:
If Point H is on line segment GI, then GH+HI = GI
Given the following parameters
GH = x + 6,
HI = x + 5, and
GI = 3x + 8
To determine the length of GH, we need to get the value of x first. To get x we will substitute the given parameters into the formula as shown;
x+6+(x+5) = 3x+8
2x+11 = 3x+8
collect like terms;
2x-3x = 8-11
-x = -3
divide both sides by -1;
-x/-1 = -3/-1
x = 3
Since GH = x+6
GH = 3+6
GH = 9
<em>Hence the numerical length of GH is 9</em>
Answer:
It is true
Step-by-step explanation:
75+{-26}+{-10}=39
75-26-10=39
75-(26+10)=39
75-36=39
39=39
true
