x = -2
Find the area of figure ABCDE if angles A, B, and C are right triangle
Answer:
85 ft.
Step-by-step explanation:
8*10=80 (the value of the the rectangle by itself)
then we take the values we are given and find the width and height of the triangle. Knowing it is a right triangle, we perform two equations,
15-10 (the total length of the polygon) 5 ft
and
8-6 (to find the height of the triangle, using the length where the hypotenuse of the triangle cuts off the rectangle) 2 ft
With this, we now have the length and width of the right triangle, and multiply them together to get 10. Because that formula only works on rectangles and squares, but we know that the triangle is a right triangle, we divide the 10 in half to get 5, which is the area of the triangle. Together, the value of the area for the rectangle and the triangle together result in 85 ft (remember to label units when in a written test!)

Which function has a smaller minimum? What is that minimum value?
a.f(x) has the smaller minimum. The minimum is -1.
b.g(x) has the smaller minimum. The minimum is -1.
c.g(x) has the smaller minimum. The minimum is -3.
d.f(x) has the smaller minimum. The minimum is -3.
Answer:
c. g(x) has the smaller minimum. The minimum is -3.Step-by-step explanation:
Given functions
f(x) = (x - 1)^2 - 1 (graphed)and
g(x) = (x - 1)^2 - 3Comparing the vertex of the functions (the minimum), we see that:
f(x) has a vertex (1, -1)g(x) has a vertex (1, -3)Correct option is c)

Can anyo help me thanks
Answer:
(-3, -5)
Step-by-step explanation:
We will multiply (6a -2b = -8) by -3, and (a - 3b = 12) by 2
Thus,
-18a + 6b = 24
2a - 6b = 24
=
-16a = 48
a= -3
Then we'll substitute,
-18(-3) + 6b = 24
54 + 6b = 24
6b = -30
b = -5
(-3, -5)

The relationship between the number of grams of carbohydrates in a loaf of bread and the number of calories the loaf
contains can be modeled by the equation y = 15x – 25, where x is the number of grams of carbohydrates, and y is
the number of calories. According to the model, which statements are correct? Select all that apply.
A. For every 1.0 gram increase in carbohydrates, the number of calories increases by about 25.0.
B. For every 2.0 gram decrease in carbohydrates, the number of calories decreases by about 30.0.
C. For every 3.5 gram decrease in carbohydrates, the number of calories decreases by about 87.5.
D. For every 7.5 gram increase in carbohydrates, the number of calories increases by about 112.5.
E. For every 10.0 gram increase in carbohydrates, the number of calories increases by about 15.0.
Answer: It would be b B. For every 2.0 gram decrease in carbohydrates, the number of calories decreases by about 30.0.

In ΔQRS, the measure of ∠S=90°, QS = 11, SR = 60, and RQ = 61. What is the value of the sine of ∠Q to the nearest hundredth?
Answer:
0.98
Step-by-step explanation:
Below is a drawing of the triangle (drawing it out is an important step if you have trouble visualizing it).
Sine = opposite/hypotenuse, in this case, SR (60) is the opposite of angle Q and RQ (61) is the hypotenuse.
Sin(angle Q) = 60/61 = 0.98
