Step-by-step explanation:
area= 1/2 (base1+base²) h
A = {1/2 (5+12)} × 4
A = {1/2 (17)} × 4
A = 8.5×4
A = 34
I think this is right
Step-by-step explanation:
Words Decimal Representation Scientific Notation
ten million 10,000,000 1 x 107
one hundred million 100,000,000 1 x 108
one billion 1,000,000,000 1 x 109
ten billion 10,000,000,000 1 x 1010
X=-198(substitute the value of x into the equation)
x-6y=90
-198-6y=90(solve the equation)
y=-48(a possible solution is)
(x,y)=(198,-48). (check yhe solution)
-198-12= 210(simplify)
-198-6(-48)=90
-210=-210( the ordered pair is a solution)
90=90
(x,y)=(198,-48)
is the answer
First find the slope, so subtract the y1 and 2 then same thing with x. -7-1=y. -2-(-3)=x. y is -8 and x is 1. divide -8 and 1. which gives you -8. SLOPE is -8. THE FORMULA for slope intercept form is Mx+B=y first insert the numbers then solve. need any more help use the app socratic and photo math
