<span>Earths crust mineral composition are silicon oxide (SiO2),Magnesium monoxide (MgO),Ferrous oxide(FeO),Calcium monoxide (CaO),Sodium dioxide(Na2O) ,Potassium dioxide(K2O), while the Earths crust are sodium,magnesium,potassium,calcium,iron,aluminum,silicon,and oxygen .Because Earth is based on chemical composition and split up into a crust,mantle,outer core and inner core.</span>
Answer: y=–2x–5
Step-by-step explanation:
The equation of a straight line:
y=mx+c
m must be the same for the two lines to be parallel.
y=mx+c
y=–2x+8 → m=–2
For a new equation:
x=–1, y=–3, m=–2, c=?
y=mx+c → –3=–2×(–1)+c
–3=2+c
c=–5
So:
y=–2x–5
X is equal to -15 , I think
