42 minus 19 is 23. 42-19=23
Answer:
(-3, 3)
explanation:
- original coordinate of C: (3, 5)
if reflected over y axis, use the formula: (x,y) → (-x, y)
If translated vertically, there will be change in y axis
- then vertically -2 units:
(-3, 5-2) → (-3, 3)
Answer:
5/4 m²
Step-by-step explanation:
Jordan is cutting 2 m by 1 1/4 m piece of rectangular paper into 2 pieces along its diagonal.What is the area of each of the pieces.
Length of the rectangular paper = 2m
width of the rectangular paper = 1 1/4m
Area of a rectangle = Length × width
= 2 × 1 1/4
= 2 × 5/4
= (2 * 5)/4
= 10/4 m²
Area of a rectangle = 10/4 m²
Diagonal divides the rectangle into 2 equal pieces
Divide area of the rectangle by 2
Area of each piece of the diagonal = Area of the rectangle / 2
= 10/4 m² / 2
= 10/4 ÷ 2
= 10/4 × 1/2
= (10*1) / (4*2)
= 10/8
= 5/4 m²
Area of each piece of the diagonal = 5/4 m²
Answer:
Step-by-step explanation:
Answer:

or

Step-by-step explanation:
we have
f(3+√2 )=f(3− √2 )=0
so
x1=3+√2 and x2=3−√2 are the roots or x-intercepts of the quadratic equation
The quadratic equation in factored form is equal to

substitute

Find the value of the coefficient a
Remember that
f(1)=−8
so
For x=-1 -----> f(x)=-8
substitute

solve for a

apply difference of squares


therefore


simplify
Applying distributive property
