35.1 is the answer to this question
Answer:
I think B but I'm not sure
Step-by-step explanation:
This is the concept of algebra: The answers to the questions will be as follows:
1. What is AD/AM in the simplest form:
AD/AB is the ratio of AD to AB. This will calculated as follows:
AD=9 units
AB=3 units
thus:
9/3=3
Hence, we conclude that the answer is D. 3
2] What is slope of BE/ slope of AE in simplest form:
slope=(Δy-axis)/(Δx-axis)
slope of AE
=(5-0)/(4-0)
=5/4
slope BE
slope=(5-0)/(4-3)=5/1=5
therefore the ratio of the two slope will be:
BE/AE
=5/(5/4)
=4
The answer is A.4
3. What is the value of x in the proportion (x-1)/5=(4x+2)/35?
To get the value of x we solve the above proportion:
(x-1)/5=(4x+2)/35
35(x-1)=5(4x+2)
35x-35=20x+10
putting like terms together we get:
35x-20x=10+35
15x=45
dividing both sides by 15
x=45/15
x=3
Hence the answer is B.3
4. What is the value of x in the proportion:
(x+1)/(x+3)=15/21
to get the value of x we solve the above:
first we begin by cross multiplying the proportion, this will give us:
21(x+1)=15(x+3)
21x+21=15x+45
putting like terms together we get:
21x-15x=45-21
6x=24
dividing both sides by 6 we get
x=4
∴ x=4
5. The lengths of the sides of a triangle are in extended ratio 3:10:12. The perimeter is 400 cm. What is the length of the longest side in cm.
solution:
Here we introduce the variable x such that the perimeter is:
3x+10x+12x=400
25x=400
x=400/25
x=16
The longest side will be:
12×16=192 cm
Answer:
96
Step-by-step explanation:
Exterior angles add up to 360
360 - 134-130 = 96
x = 96
F(x)=f(x)=x3+2x2−x−2
0=x3+2x2−x−2
0=(1)3+2(1)2−(1)−2 −−> 1+2−1−2 −−> =0, so 1 works.
0=(−1+2(−1−1)−2 −> −1+2+1−2 −>0 −−> so,
f(x)=(−2)3+2(−2)2−(−2)−2 −> −8+8+2−2 −> 0 So, −2 also works.
make x=0
f(x)=(0)3+2(0)2−(0)−2 ⇒ 0+0−0−2 ⇒ −2. So y−intercept is −2
the x-intercepts are 1, -1 & -2 OR (1,0) (-1,0) (-2,0) and y intercept is -2 OR (0,-2) then you can graph it.
