Step-by-step explanation:
Answer:
C)
Step-by-step explanation:
Solution of the equation is where the two lines intersects.
So, the two lines intersect at ( 1 , -1)
You can substitute this point in the two equation.
y = x -2
Her plug in x = 1
y = 1 -2
y = -1
Same way,
y = 4x - 5
y = 4*1 - 5
y = 4 - 5
y = -1
Answer:
a is -1
b is 31
c is 7
Step-by-step explanation:
-x^2+31x+1=0
ax^2+bx+c=0
Answer:
shape AREA= 35cm^2
Step-by-step explanation:
you should know that this shape is a combination of triangle and trapezoid. therefore you have to find the area of each shape and add them.
A=h/2(b1 + b2) for trapezoid
A=2/2((4+4)+4)
A=1*12
A=12cm^2
A=bh/2. for TRIANGLE
A=1/2((4+4)*5.75)
A=1/2(46)
A=23cm^2
shape AREA= triangle AREA + trapezoid AREA
shape AREA=12cm^2 + 23cm^2
shape AREA= 35cm^2
