Answer:
x = -10
Step-by-step explanation:
1.4x = -7.9 -6.1
1.4x = -14
x = -14÷1.4
x= -10
Answer:
Step-by-step explanation:
Given: r(x)=3x-1 and s(x)= 2x+1
We have to find
That is to find
first find r (6) and s(6) , then substitute, we get,
r(6)
r(x) = 3x - 1
Put x = 6 , we get
r(6) = 3(6) -1 = 18 - 1 = 17
s(6)
s(x) = 2x + 1
Put x = 6 , we get
s(6) = 2(6) + 1 = 12 + 1 = 13
Thus,
Using the slope concept, it is found that the angle of elevation to the top of the bridges is of 57.7º.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>.
It's also the tangent of the angle of depression.
In this problem:
- The horizontal change is of 60 m.
- The vertical change is of 100 - 5 = 95 m.
Hence:
The angle of elevation to the top of the bridges is of 57.7º.

Answer:
Answer 21ab
Step-by-step explanation:
First you do 3 times 3a which you get 9a then to 3 times 4b and you get 12b. So 12b plus 9a equals 21ab
