Answer:
2/3
Step-by-step explanation:
First, we read the two points with circles off the graph.
They are (-4, -5) and (5, 1).
slope = (y2 - y1)/(x2 - x1) = (-5 - 1)/(-4 - 5) = -6/(-9) = 2/3
Answer: 2/3

What is the surface area of the rectangular prism?
36 cm²
108 cm²
72 cm ²
54 cm²
Answer:
SA = 108cm² (the 2nd option)
Step-by-step explanation:
h = 4
l = 3
w = 6
SA = 2(lw + lh + wh)
SA = 2((3)(6) + (3)(4) + (6)(4))
SA = 2(18 + 12 + 24)
SA = 2(54)
SA = 108cm²
The surface area of the rectangular prism is 108cm².
Calculation of the surface area of the rectangular prism:Since
height = 4
length = 3
width = 6
So, here the surface area is
SA = 2(lw + lh + wh)
= 2((3)(6) + (3)(4) + (6)(4))
= 2(18 + 12 + 24)
= 2(54)
= 108cm²
hence, The surface area of the rectangular prism is 108cm².

12. Triangle XYZ is a right triangle. Angle Y is the right angle. If tan Z = 3/4 , then Predict the tan X. A) 4/5 B) 3/4 C) 3/5 D) 4/3
Answer:
D) 4/3
Step-by-step explanation:
12. Triangle XYZ is a right triangle. Angle Y is the right angle. If tan Z = 3/4 , then Predict the tan X. A) 4/5 B) 3/4 C) 3/5 D) 4/3
IF tan Z = 3/4
Since m<Y = 90 degrees
Let the opposite side be XY
YZ be the adjacent side
and XZ is the hypotenuse
Given
tan theta = opp/adj
opp = 3 = XY
adj = 4 = YZ
Get the hypotenuse
hyp^2 = 3^2 + 4^2
hyp^2 = 9 + 16
hyp^2 = 25
hyp = √25
hyp = 5
for tanX;
Side opposite to angle X is YZ
Adjacent side = XY = 3
opposite = YZ = 4
Tan X = YZ/XY
Tan X = 4/3
Hence the prediction of Tan X is 4/3

What is the multiplicative identity of the complex number 4 + 8i
Answer:
1
Step-by-step explanation:
when you multiply an complex number by its multiplicatuive identity, in case 4+8i, you would multiply both the top and the bottom by 4-8i which is actually the value one since we cannot actually change the whole value of the number. By multiplying it by 1 and we get the same value without the imaginary number
(sorry if this doesn't make sense but I hope it helps)
about that did you forget to put -4 + 8i just to make sure about it because I am not sure if you forget it or not just making sure

A new road was added near Riana's neighborhood. The road is 5 miles long, and the city plans 1/10 to place a streetlight every mile. There already is a streetlight at the beginning of the new road. How many streetlights will be placed on the new road?
Answer:
= 49
Answer.
Step-by-step explanation:
Solution:-
Length of the road = 5 miles
Distance between every two streetlights = 1/10 miles
Total number of streetlights placed on the new road = 5 ÷ 1/10
= 5*10
= 50 streetlights
As there is already a streetlight at the beginning of the new road, so the number streetlights will be = 50 - 1

Find f(-) if f(n) = 5n + 6.
Answer:
f(-1) = 1
Step-by-step explanation:
Are you missing a number after the negative in f(-)?
If so, let me solve for f(-1) so substitute in the n with a -1 so f(-1) = 5(-1) + 6
so f(-1) = -5 + 6 so f(-1) = 1
