f(4)=4²+3(4)-1
f(4)=16+12-1
f(4)=28-1
f(4)=27
it approaches 27 as x approaches 4
Answer:
Simplifying
x = 4.5 + -0.5y
Step-by-step explanation:
Answer:
x = 3, line AB = 17 , and line CD = 17
y = 10, angle A = 70, and angle D = 70
Step-by-step explanation:
well since their the same length you can put them equal to each otheir
5x + 2 = 8x - 7
subtract 5x by both sides to get --> 2 = 3x -7
add 7 to both sides and get --> 9 = 3x
divide 3 by both sides to get x = 3
now plug it back in each equation we started with and get you answers
Same steps for y but different equations
~ Use the distance formula to measure the lengths of the sides.
~ Use the slope to check whether sides are perpendicular and form right angles.
~ Use the slope to check whether the diagonals are perpendicular to each.
I hope this helps ^-^
