Answer:
y=-6x+2
Step-by-step explanation:
slope-intercept equation is y=mx+b
m=slope and b=y-intercept, substitute slope for m and y-intercept for b
4 x = 25 log(x)

Let, one leg be x units.
since the other leg is 9.0 units shorter than the other,
the measure of the other leg =x-9
hypotenuse =13.0 units
According to Pythagorean theorem, the square of the hypotenuse is equal to the sum of squares of the other two sides.
x^2 +(x-9)^2 =13^2
x^2 + x^2 -18x +81 = 169
2x^2-18x-88=0
Divide the whole equation by 2
x^2 - 9x -44 =0
Let's use the quadratic formula to find the roots.
formula: x= [-b ± sqrt(b^2-4*a*c)]/2*a
a=1 b=-9 c=-44
x= [9±sqrt(81+176)]/2
=[9±sqrt(257)]/2
=[9±16.03]/2
=25.03/2 or -7.03/2
length of a triangle cannot be negative,
Therefore, x=25.03/2 =12.52
one leg =12.5 units
other leg =12.52-9 =3.5 units
Answer:
45
Step-by-step explanation:
because this is a 45 45 90 triangle
Answer:
If you mean the area then 21ft
Step-by-step explanation:
3ft times 7ft= 21ft
Formula for area of parallelogram
A=BH
or
A=B times H
B is base and H is height
Hopefully that helps:)
