Answer:
f(-2) = 20
Step-by-step explanation:
f(x) = 2x² - 3x + 6
f(-2) = 2(-2)² - 3(-2) + 6
= 2(4) + 6 + 6
= 8 + 12
= 20
Answer:
2(w+10)=50
Step-by-step explanation:
rectangle two sides are equal and the other two sides are equal
so we know two sides are ten in this equation the w can be the unknown sides so 2*w and 2*10 = 50
2(15+10)=50
Answer:
The slope of a line perpendicular to the line whose equation is 4x - 5y = 10 is -5/4.
Step-by-step explanation:
provided the equation;
4x- 5y=10.(let it be equation of line1 )
and the other line be line2
from perpendicularty principle
M1×M2= -1
BUT for M1(slope of line L1)
y= mx+c
where "c" is constant value.
"m" is slope.
therefore
5y= 4x - 10
(dividing by five throughout)
y=(4x/5) - 2
y= (4/5)x - 2
therefore M1= (4/5)
Returning back to our principle
M1×M2= -1
(4/5)M2=-1
<u>M2= -5/4</u>
The answer is 21, I think.
