y=3x^4 inverse: u switch the x and y: x=3y^4 now u solve for y: x/3=y^4 fourth root of x/3=y
pretend $1 is x and $5 is y x+8=y *bc you have to add 8 $1 to have the same number of $1 as $5 1x+5y=124 *this is basically saying that there is an "x" number of $1 bill plus a "y" number of $5 will get u $124 now use elimination: since y=x+8 plug "x+8...
this is similar to the question I answered on the question after this: pretend nickels=x dimes=y x+y=21 *total number of dimes and nickels is 21 .05x+.1y=$1.65 *the value of x is .5 and the value of y is .1 so when you multiply it by the number of x and y you get $1.65 now use...
d)6*35 prime factors of a: 11,11 prime factors of b: 11,3,5 prime factors of c: 7,19 prime factors of d: 2,3,5,7 just simplify each answer choices into the smallest multiples u can.... like in "c" theres nothing u can multiply to make 7 or 19 so they r the prime factors
n^2-2n-4=0 a=1 b=-2 c=-4 then use quadratic formula x=(-b+sqrt(b^2-4ac))/(2a) x=(-b-sqrt(b^2-4ac))/(2a) x=1+sqrt(5) x=1-sqrt(5)
b)6 for largest possible average u add on highest numbers u can: next highest numbers would be 9, 8, 6, and 5 1+7+9+8+6+5=36 36/6=6
As Rita drives north on Highway 281 through San Antonio, her actual bearing is 311 degrees. If she is driving at 50mph what is her velocity in the east- west direction?
Pre-Calculus follow up question Reiny
Determine the number of triangles that can be formed with the given information. and if it forms two possible triangles solve all unknown angles and sides Angle A=116 degrees a=10 b=11 but if you add 81.4 (measure of angle B) plus 116 (measure of angle A) you get 197.368 which...
thank you so much!!!
but if you add 81.4 (measure of angle B) plus 116 (measure of angle A) you get 197.368 which is over 180 degrees.... so that would make measure of angle C negative which is why I'm confused
