Answer:
y = 23x-82
Step-by-step explanation:
The equation is written in the form y = mx+b
We need to find the slope
m = (y2-y1)/(x2-x1)
= (79-56)/(7-6)
= 23/1
The slope is 23
y= 23x +b
Put in a point for x and y to determine b
10 =23(4) +b
10 =92 +b
Subtract 92 from each side
10-92 = 92-92 +b
-82 =b
The equation is
y = 23x-82
Answer:
40%
Step-by-step explanation:
10% of 40 is 4
4x4=16 meaning that 10% x 4 = 40%
Since we know he earns $75 a week we can write
$75x
And we know he already has $520, so just add that.
+$520
So we would set up our algebraic expression like this.
$75x + $520
Good Luck! :)
Answer:
Undefined
Step-by-step explanation:
To simplify, find tan 90. Tan 90 isn't possible to find. Tangent is the value of Sine divided by Cosine. The sin 90 = 1. The cos 90 = 0. When you divide to find the tangent, it becomes 1 divided by 0. However, nothing can be divided by zero. The answer is undefined.
Answer:
m∠4=160°
m∠6=20°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠6+m∠4=180° ----> equation A (by consecutive interior angles)
m∠6=(1/8)m∠4 ---> equation B
substitute equation B in equation A
(1/8)m∠4+m∠4=180°
Solve for m∠4
(9/8)m∠4=180°
m∠4=180°(8)/9
m∠4=160°
<em>Find the measure of m∠6</em>
m∠6=(1/8)m∠4
m∠6=(1/8)(160°)=20°
