Is the equation y=85x-600 linear? Explain why or why not.

2 answers:

6 0

Yes, it has a slope and a y-intercept, using the linear equation, y=mx+b.

Not sure if this answer is in depth enough, but its definitely a linear function.

Yes the equation is linear because the linear equation is y=mx+b and y=85x-600 is linear.

Seth traveled 1 mile in 57.1 seconds. About how fast does Seth travel I. Miles per hour?

enyata [817]

57.1 seconds = 57.1 seconds * $\frac{1minute}{60seconds} * \frac{1hour}{60minutes}$ = 0.01057 hour
1 mile / 57.1 seconds = 1 mile / 0.01057 hour = 94.57 miles/hour

Find the value of x.

slavikrds [6]

Answer:

$x=11$

Step-by-step explanation:

we know that

The Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

In this problem

$(x+5)=\frac{1}{2}(3x-1)$

solve for x

Multiply by 2 both sides

$2x+10=3x-1$

subtract 2x both sides

$10=3x-1-2x$

$10=x-1$

Adds 1 both sides

$x=11$

Decide whether the sequence 4,10,20,34,52 ....... is a linear model,

Alecsey [184]

Answer:

Lineal.

Step-by-step explanation:

To determine if the sequence 4,10,20,34,52 ....... is a linear model, a quadratic model or a cubic model, the following mathematical logical reasoning must be carried out:

4 to 10 = +6

10 to 20 = +10

20 to 34 = +14

34 to 52 = +18

Thus, we can see at a glance that the sequence increases 4 numbers in each digit, adding first 6, then 10, then 14 and so on, with which the next numbers in that sequence should be 74 (+22), 100 ( +26), 130 (+30), 164 (+34), and so on.

Therefore, since there is no quadratic or cubic relationship, the sequence is linear.
