Mathematics
1 answer:
Lilit [14]1 year ago
7 0

Step-by-step explanation:

To find the unit rate of a graph find two points. and set up this equation

\frac{y2 - y1}{x2 - x1}

Then solve for the Unit rate which can also be referred to as slope, or change in y over x

Hope this helps!

Simiplify without using absolute value bars, Solve for |x +7| for x>=7
Pavlova-9 [17]

9514 1404 393

Answer:

  x +7

Step-by-step explanation:

The argument of the absolute value function is positive for any x > -7. The required domain is a subset of that, so the absolute value function does not change its argument.

  |x+7| for x ≥ 7 is x +7

PLS HELP!!!
stira [4]

Answer: Option 4

Step-by-step explanation:

\mathbf{u}=\langle 70 \cos 230^{\circ}, 70 \sin 230^{\circ} \rangle\\\\\mathbf{v}=\langle 60\cos 140^{\circ}, 60 \sin 140^{\circ} \rangle\\\\\mathbf{w}=\langle 80 \cos 30^{\circ}, 80 \sin 30^{\circ} \rangle\\\\\\\therefore \mathbf{u}+\mathbf{v}+\mathbf{w}=\langle 70 \cos 230^{\circ}+60 \cos 140^{\circ}+80 \cos 30^{\circ}, 70 \sin 230^{\circ}+60 \sin 140^{\circ}+80 \sin 30^{\circ} \rangle\\\\ \approx \langle -21.675, 24.944 \rangle

\implies |\mathbf{u}+\mathbf{v}+\mathbf{w}| \approx \sqrt{(-21.675)^2 + (24.944)^2} \approx 33.046

Direction: The vector is in the second quadrant, so the direction is about 180^{\circ}-\arctan \left(\frac{24.944}{-21.675} \right) \approx 131^{\circ}

At Martin Nature Center, the park ranger was showing Mrs. Rhames' class a comparison of a tree's age and the diameter of the tre
sdas [7]
If x is the age and y is the diameter of the trunk, write the equation:
ax+b=y

We must solve for a and b with the given information.

If (x, y) is (1, 4), we have:

a+b=4

If (x, y) is (10, 25), we have:

10a+b=25

Multiply the first equation by 10 to get:

10a+10b=40

Subtract the second equation from this to get:

9b=25

Thus b=25/9.  a=4-25/9=11/9, so our equation is 11x/9+25/9=y.
