Answer:

x=66°

Step-by-step explanation:

We know that the total angle measure in a triangle is always 180°, so first we need to find the angle value of BAC. They give us a straight line aligning with this angle and measure of 98° for the angle DAB (which is forming other part of line) and a line is 180° so we subtract and find that angle BAC is 82°.

Now that we know the angle measure of 2 angles in the triangle, we add them up and get 114°. Now we subtract this from 180° and get 66°, which is the measure of x.

For a diamond problem what two numbers' sums equal 31 and their product is 234?
s344n2d4d5 [400]

Let

x-------> the first number

y------> the second number


we know that

x+y=31

x=31-y

equation 1


x*y=234

equation 2


substitute equation 1 in equation 2

(31-y)*y=234\\ 31y-y^{2} =234\\ -y^{2} +31y-234=0



using a graph tool-----> to resolve the second order equation

see the attached figure


the solution is

What is the equation of the line that passes through the point (4,-7) and has a
aalyn [17]

Answer:

y = -\frac{1}{2} x -5

point slope form....

y - (-7) = -1/2(x-4)

y + 7 = -x/2 + 2

2y + 14 = -x + 4

2y = -x -10

y = -1/2 x - 5

Help please?!?!?!?!?!?!?
nadezda [96]

Answer:

Choice D is  correct answer.

Step-by-step explanation:

We have given two function.

f(x) =2ˣ+5x  and g(x)  = 3x-5

We have to find the addition of given two function.

(f+g)(x) =  ?

The formula to find the addition, we have

(f+g)(x) = f(x) + g(x)

Putting given values in above formula, we have

(f+g)(x) =   (2ˣ+5x)+(3x-5)

(f+g)(x) =   2ˣ+5x+3x-5

Adding like terms, we have

(f+g)(x) =   2ˣ+8x-5 which is the answer.
