Hi! i’m going to assume that the 2 next to the x is an exponent, so forgive me if i answer incorrectly. after plugging in x for -6 your equation should be 4(-6^2+3)-2y (the ^ indicates a exponent)
multiply the exponents and get:
4(36+3)-2y
add the parentheses:
4(39)-2y
multiply by 4:
156-2y
and divide by -2 (to isolate the y)
y=-78
this might be wrong, but i hope it helps :)
You do 390/100 = 180/x then 390×X=390X
180×100=18000
390X=18000
390X÷390=X
18000÷390=46.15384615=46%
Answer:
x=<-11
Step-by-step explanation:
3x+18=<-15
3x=<-33
x=<-11
Answer:
Option :" Use distance formula to prove that the lengths of the diagonals are equal" is correct
Step-by-step explanation:
Option : Use distance formula to prove that the lengths of the diagonals are equal" is correct.
Because " By using the coordinate geometry to prove that the diagonals of the rectangle are congruent, first we have to find the lengths of the top and bottom of the rectangle and then solve it for the lengths of the diagonals by using the distance formula".
3x^2 = 48; Divide both sides by 3 to isolate the variable.
3x^2 / 3 = x^2; 48 / 3 = 16
x^2 = 16; Square root both sides to determine the value for x.
x^2 / x = x; sq rt of 16 = 4.
Your ending equation is x = 4.
I hope this helps!
