Answer:
x = 50
GI = 72
ET = 56
Step-by-step explanation:
Corresponding sides of similar triangles PIG and LET are proportional.
__
GI/PI = ET/LT . . . . . . . . . corresponding sides are proportional
(x +22)/9 = (x +6)/7 . . . . . using the given values in the proportion
7(x +22) = 9(x +6) . . . . . . . cross multiply
7x +154 = 9x +54 . . . . eliminate parentheses
100 = 2x . . . . . . . . . subtract 7x+54
50 = x . . . . . . . . divide by 2
GI = x +22 = 50 +22 = 72
ET = x +6 = 50 +6 = 56
Answer: Candace ate servings.
Step-by-step explanation:
Given: Candace ate cup of cereal.
The box of cereal states that 1 serving of cereal = cup.
i.e. 1 cup = servings [Multiply both sides]
⇒ cup = servings
= servings [which is the number of servings she ate]
Hence, Candace ate servings.
Answer:
it is 42069t
Step-by-step explanation:
Answer:
- Graph B has one real root.
- Graph A has a negative discriminant
- Graph C has an equation with the coefficients a=1, b=4, c=-2.
Step-by-step explanation:
The number of real roots is the number of places where the graph intersects the x-axis. When the discriminant is negative, there are none. Graph A does not cross the x-axis, so has a negative discriminant.
Graph B intersects the x-axis at one point, so it has one real root.
Graph C has two real roots, consistent with the positive discriminant associated with the given coefficients:
_____
For quadratic ...
the discriminant is ...
and the roots are ...
Then the roots are only real when the discriminant is non-negative. The square root function will not give real values for a negative argument.
