Answer:
a. Simplify each term. 49/2+0
Add 49/2 and 0.
49/2
The result can be shown in multiple forms.
Exact Form:
49/2
b. Replace the variable a with −13 in the expression.
−(−1/3)²b²−3(−1/3)³b²
Replace the variable b with −1 in the expression.
−(−1/3)²(−1)²−3(−1/3)³(−1)²
Simplify each term. −1/9+1/9 = 0
Combine fractions. 0

#5 = 53° #7 = 125° #6 = 55° #2 = 72° #3 = 55° #1 = 53° #4 = 127°
triangle = 180°
alternating interior angles are the same (#6 & #3 and #5 and #1)
#3 and #7 should equal 180°
#1 and #4 should also equal 180°
#6 and #7 should equal 180°
#4 and #5 should equal 180°
Answer:
x/2 = 12.5/5
5 · x = 12.5 · 2
5x = 25
5x / 5 = 25 / 5
x = 5

Answer:
y=-1/4x+8
Step-by-step explanation:
To find the equation of a line that is perpendicular to a line, you would take the opposite reciprocal of the slope.
Before that, we need to change the equation into slope-intercept form.
-4x+y=10
y=4x+10
The opposite reciprocal of the slope is -1/4.
Now, let's use the point-slope formula to find our equation of the line that passes through (-4,9).
y-y1=m(x-x1)
y-9=-1/4(x-(-4))
y-9=-1/4x-1
y=-1/4x+8
