The junior class is selling Caramel Apple lollipops and Gourmet lollipops to raise money for prom. They profit 50 cents and 75 c

Likurg_2 [28]

If we letx as the number of Caramel Apple lollipops soldy as the number of Gourmet lollipops sold
Then, we can make an inequality from the given which is0.50x + 0.75y ≥ 250The graph of this inequality would have a y intercept of500 and a slope of 2/3 and includes all the points above the solid line.
hope this helps and brainliest :)

Which congruence theorem can be used to prove △BDA ≅ △DBC? Triangles B D A and D B C share side D B. Angles C B D and A D B are

Tomtit [17]

Answer:

A. Hypotenuse-leg (HL) congruence.

HL, when you have 2 right triangles and their hypotenuses are congruent you are able to say HL

Step-by-step explanation:

We know that the hypotenuse-leg theorem states that if the hypotenuse and one leg of a right triangle are congruent to hypotenuse and corresponding leg of another right triangle, then the triangles are congruent.

hypotenuse(AB) of △BDA equals to hypotenuse (CD) of △DBC.

BDA and DBC share a common side DB.

Using Pythagorean theorem we will get,

$CD^{2}=DB^{2}+BC^{2}...(1) \\\\AB^{2}=DB^{2}+AD^{2}...(2)$

We have been given that CD=AB, Upon using this information we will get,

$DB^{2}+BC^{2}=DB^{2}+AD^{2}$

Upon subtracting $DB^{2}$ from both sides of our equation we will get,

$BC^{2}=AD^{2}\\\\BC=AD$

<h3>Therefore, by HL congruence △BDA ≅ △DBC.</h3>

Step-by-step explanation:

OA=AC=OC=2 (equal triangle)

which means angle O =60 degree

tan 60 = AB / 2

AB = 2 tan 60 =

In which interval is the radical function f of x is equal to the square root of the quantity x squared plus 2 times x minus 15 e

sergij07 [2.7K]

Using function concepts, it is found that it is increasing on the interval:

(–∞, –5] ∪ [3, ∞)

---------------

The function is given by:

$f(x) = \sqrt{x^2 + 2x - 15}$

The graph is given at the end of this question.

If the function is pointing upwards, it is increasing. Otherwise, it is decreasing.
In the graph, it can be seen that it is pointing upwards for x of -5 and less, or 3 and higher, thus, the interval is:

(–∞, –5] ∪ [3, ∞)
