<span>Which ordered pair is the best estimate for the solution to the system?
</span>A. (2, −6.5)
valina [46]4 years ago
6 0

Answer:

Option A (2,-6.5)

Step-by-step explanation:

we know that

The solution of the system is the intersection point both graphs

The x-coordinate of the intersection point  is 2

The y-coordinate of the intersection point belong to the interval---> (-6.5,-6)

see the attached figure to better understand the problem

therefore

the best estimate for the solution to the system is the point (2,-6.5)

Help will give braniest answer to person who is correct find the degree measure of each angle in the triangle
Irina-Kira [14]

Answer:

Angle I = 90 degrees

Angle J = 61 degrees

Angle K = 29 degrees

Step-by-step explanation:

Angle I is given

We know that the angles in all triangles add up to 180. Since we are given that angle I is equal to 90 degrees, we now know that angle J + angle K = 90 degrees:

(5x+26) + (2x+15) = 90

Solve for X:

7x + 41 = 90

7x = 49

x = 7

Angle J =  (5x + 26) = (5(7) + 26) = 61

Angle K = (2x + 15) = (2(7) + 15) = 29

Checking your work: 61 + 29 = 90

Soon after taking an aspirin, a patient has absorbed 320 mg of the drug. after 3 hours, only 40 mg remain. find an exponential m
Anastaziya [24]
The equation will be of the form:
A(t)= A_{0} e^{rt}
where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:
40=320e^{3r}
Rearranging and taking natural logs of both sides, we get:
ln\ 0.125=3r
r=\frac{ln\ 0.125}{3}=-0.693
The required model is:
A=A _{0} e^{-0.693t}

Will factor the express 36xyz + 24xy − 16x by dividing each term by a common fact
sesenic [268]

\\ \bull\tt\longmapsto 36xyz+24xy-16x

  • Divide by 4

\\ \bull\tt\longmapsto \dfrac{36xyz}{4}+\dfrac{24xy}{4}-\dfrac{16x}{4}

\\ \bull\tt\longmapsto 9xyz+6xy-4x

  • Divide by x

\\ \bull\tt\longmapsto \dfrac{9xyz}{x}+\dfrac{6xy}{x}-\dfrac{4x}{x}

\\ \bull\tt\longmapsto 9yz+6y-4

In the given figure , if AB  l  BD  , then the value of x is 
gladu [14]
In the figure as we can see - 

Angle 32 = Angle DAB                            (vertically opposite angles)

Angle ABD = 90 degrees

And we know that,

Sum of all angles of triangle =180 degrees

So,

32+90+x+14=180

136+x=180

x=180-136

x=44 degrees
