What is the equation for this situation?
The table shows a representation of the number of miles
a car drives over time.
Hours, x
Miles, y
Which could NOT be a point on this table?
3
195
4
260
5
325
6
390
Pattern: Each x value is multiplied by 65
to get each y value.
Answers
Answer:
Equation: y = 65x
Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.
Step-by-step explanation:
Pick any two points to find slope, let's got with (3, 195) and (4, 260):
slope m = (y₂- y₁) / (x₂ - x₁)
= (260 - 195) / (4 - 3)
= 65 / 1
m = 65
Find y-intercept by using m from above and another point from your table, let's go with (5, 325):
y = mx + b
325 = 65(5) + b
325 = 325 + b
b = 0
Use m and b to form equation of line:
y = mx + b
y = 65x + 0
y = 65x
Check:
point (3, 195): 195 = 65(3) ====> 195 = 195
point (4, 260): 260 = 65(4) ====> 260 = 260
point (5, 325): 325 = 65(5) ====> 325 = 325
point (6, 390): 390 = 65(6) ====> 390 = 390
Example of a point that doesn't belong on table:
point (8, 500): 500 = 65(8) ====> 500 ≠ 520
The equation of the line is y = 95x option (D) and the point (8, 445) is not on the line option (B) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The table shows a representation of the number of miles a car drives over time. Hours, x
The equation of the line:
y - 195 = (260-195)/(4-3)[x - 3]
y - 195 = 65(x - 3)
y = 65x - 195 + 195
y = 65x
Plug x = 8
y = 195(8) = 1560
Thus, the equation of the line is y = 95x option (D) and the point (8, 445) is not on the line option (B) is correct.
The missing options are:
What is the equation for this situation?
y = 195x +3y = 195xy = 65x +3y = 65xWhich could NOT be a point on this table?

Follow these steps to construct a triangle to represent the given information:
Draw a ray in the direction S 20° E from point P. Create a circle with radius 43.5. (Note that you'll be scaling down all the distances in miles by a factor of 10: 435 ÷ 10 = 43.5.) Label the point where the circle intersects the ray as C (Cali).
Draw a ray in the direction S 81° E from P. Mark an arbitrary point on this ray, and label it S.
Create a line through point S that is parallel to the north-south line through P.
Using the line passing through point S, draw a ray that is S 53° W.
Move point S along line PS until the ray S 53° W from S passes through point C. This position of S locates San Cristobal.

∠TUS=99-12x
∠TUS+∠TUV=180

Angle TUV is exterior angle to triangle TUS. Exterior angle measure is equal to sum of non-adjacent interior angles:
∠TUV = ∠STU + ∠TSU24x + 9 = 81 + 12xSolving for x
24x - 12x = 81 - 912x = 72x = 72/12x = 6°Finding angle measure of ∠TSU

The equation 2x + 3y = 60 describes the number of tomato plants, x, and lettuce plants, y, that Aneil can plant in the garden. Graph this function and find the intercepts. What does each intercept represent?
Answers
Step-by-step explanation:
The more regular way of presenting such a graph is y = -2/3 x + 20
(Put the x on the right and made sure that the y has a coefficient of 1.)
Coefficient means the number in front of the letter (in this case).
x intercept = 30

y intercept = 20

In Triangle ABC, ∠A + ∠B = 65° and ∠B + ∠C = 140°.Find the value of ∠B and ∠C.
Can anybody pls give the answer fast...
Answers
A + B = 65...Equation 1
B + C = 140...Equation 2
Solve Equation B for C.
C = 140 - B
The sum of the angles in a triangle is 180 degrees.
We know that A + B = 65.
65 + C = 180
We know that C = 140 - B.
65 + 140 - B = 180
205 - B = 180
-B = 180 - 205
-B = -25
B = -25/-1
B = 25
Plug B = 25 into B + C = 140 to find angle C.
25 + C = 140
C = 140 - 25
C = 115
Angle B = 25°.
Angle C = 115°.
