The slope is the change in y over change in x
Given the points (1,8), (2,11), (3,14), (2,17) we can use the table to figure out what our equation will be
Notice on the table as you go on the y term from 8 to 11 to 14 to 17 you are having a constant rate of change of 3. So that’s your change in y
On the left side which is your x, you are going up by 1 every time because it’s {1,2,3,4} So your change in x is 1
Your slope or m in y=mx+b can be found by using the following formula
Change in y/change in x
So here our change in y is 3 and our change in x is 1. So that means our slope is
m=3/1 = 3
y=3x+b
To find b, you can plug in one of the points. Let’s use (1,8). So x=1 and y=8. Now we can plug these in and solve for b.
8=3(1)+b
8=3+b
Subtracting 3 on both sides we have
b=5
Therefore given y=3x+(b) we can plug b in to obtain the following equation
y=3x+5. So that’s your answer

Subtract the length twice, then divide the remainder to find the width.
122-35-35=52
52/2 =26
Answer:
28.8
Step-by-step explanation:
23+2x+3x+13=180 simplify the left side
5x+36=180 subtract 36 from both sides
5x=144 divide both sides by 5 to isolate the variable
x=28.8
Answer:
Scalene triangle as there are no sides given.
or,
Measure it using a ruler and classify it based on the result.
Step-by-step explanation:
Scalene triangle = No sides are equal.
Isosceles triangle = 2 sides equal.
Equilateral triangle = All sides equal.
Right angled triangle = One angle is 90.
Since, the picture hasn't given any sides, i am gonna say it's a scalene triangle.
If, the triangle is for measure, measure it using a ruler and classify it based on the result.
Answer:
x = 65.03°
Step-by-step explanation:
To solve for x, we have to apply trigonometric ratio.
Recall: SOH CAH TOA
From the diagram, we know the following:
Reference angle = x
Hypotenuse = 45
Adjacent = 19
Since we know the Hyp and Adj, we would apply CAH, which is:
Cos x = Adj/Hyp
Plug in the values
x = 65.0250346°
x = 65.03° (nearest hundredth)
