EXPLANATION
The given equations are:
y = −2x + 13
y = 2x − 3
We equate the two equations to get
−2x + 13=2x − 3
Group similar terms:
-2x-2x=-3-13
-4x=-16
Divide both sides by -4,
x=4
Put x=4 into equation (2)
y=2(4)-3
y=5
The two graphs should intersect at:
(4,5)
Answer:
n=10
Step-by-step explanation:
6 = n-4
Add 4 to each side
6+4 = n-4+4
10 =n
Answer:
15
Step-by-step explanation:
All sides of a rhombus are equal, so
Percent literally means per one-hundred so:
365(p/100)=146 multiply both sides by 100
365p=14600 divide both sides by 365
p=40%
"Joint variation<span>" means "directly, but with two or more variables". Thus, we write as follows:
j </span>α gv
<span>
We insert proportionality constant k, to change it to equality.
j = kgv
We solve k,
1 = k (4)(3)
k =1/12
j = gv/12
j = 8(11)/12
j = 22/3</span>
