Danni is training for a marathon. Her target speed is 25 miles per hour. She currently runs 15 miles in 1/2 and hour. Does she achieve her target speed for her run?

Answer:

k ≠ 3

Step-by-step explanation:

Given the system of equation;

kx - y = 2 ------------------- 1

6x - 2y = 3 -------------------- 2

Rewriting the equations in the format ax+by+c = 0

Equation 1 becomes kx - y - 2 = 0

Equation 2 becomes 6x - 2y - 3 = 0

where a₁ = k, b₁ = -1 and c₁ = -2  and a₂ = 6, b₂ = -2 and c₂ = -3

For the system of equation to have a unique solution the following must be true;

a₁/a₂ ≠ b₁/b₁

Substituting the coefficients into the condition, we will have;

k/6 ≠ -1/-2

k/6 ≠ 1/2

Cross multiplying we will have;

2k ≠ 6

k ≠ 6/2

k ≠ 3

This means that k can be any other real values except 3 for the system of equation to have a unique solution.

7/-3

Step-by-step explanation:

6--1=7

-2-1=-3

Answer:

The slope is m=-7/3

m=y²-y¹/x²-x¹

m=(-1)-6/1-(-2)

m=-7/3

Answer:

So if you Divided the number of students to the number of the teachers you will have 19 students to each one teacher which means:

Step-by-step explanation:

100÷5=20 ( 19 students & 1 teacher )

science each bus can hold a maximum of 40 people.

100 = 20 20. 20. 20. 20

20 + 20 = 40 ( first bus )

20 + 20 = 40 ( second bus )

last 20 alone ( third bus )

The final answer is the fewest number of buses required for the field trip is 3 buses.

\therefore m\angle L = 30\degree\\

By \:30°-60°-90° \:\triangle \:theorem:\\

Answer:

2(n+3) - 6 = 2n

Step-by-step explanation:

Let n stand for lonnie's starting number.

Kristy asks to add 3 to the number. It will become (n+3)

Now he ask to multiply the sum by 2. It will become 2(n+3).

Finally, he ask to subtract 6. It will become 2(n+3) - 6

The expression is : 2(n+3) - 6.

We can simplify it as follows :

= 2n+6-6

= 2n

Hence, the required expression is 2n.

Answer:

4 6-packs would cost $14.40

8 6-packs would cost $28.80

1 juice would cost $0.60

Answer:

First you can find the rate of change to be 4.25. Then you can subtract 4.25 repeatedly until you get to an output with an input of zero. The initial value is the output when the input is zero. The initial value after subtracting 4.25 three times is 29.50. Because the inputs go by 2, the rate of change is half the difference of the outputs, or 4.25. Subtract 4.25 repeatedly 3 times to get to an output with an input of 0. Calculate 42.25 – (3 x 4.25).  The initial value is 29.50.
