The Solution to this system of equations is No Solution.
Graph like this:
In this graph it clearly shows that the lines never meet each other which means it is a no solution.

Which statement is correct with respect to f(x) = -3|x − 1| + 12?

Talja [164]

Answer:

The V-shaped graph opens downward, and its vertex lies at (1, 12).

Step-by-step explanation:

first, plot the graph of f(x),

take some 5 random negative and positive x values and then find corresponding f[x] values.plot f(x) on y-axis. now, plot these points on the graph and finally join all the points. this gives u the required graph.

I have plotted the graph and uploaded it.

refer it.

by seeing the graph, we can easily say that,The V-shaped graph opens downward, and its vertex lies at (1, 12).

Solve 4y-1=7 plz step by step

miv72 [106K]

Hi,

Here we are going to be working on isolating the variable y, and seeing what its value equates to.

To do this, we must try and get the variable y on one side of the equation by itself.

Let's look at step one -

4y - 1 = 7

We want to get rid of the 1 since we need to isolate x. We do this by doing the inverse of its operation. Since 1 is negative, if we add positive 1 to it - we will get 0, thereby being closer to isolating y.

However, when we do something on one side of the equation we must do it on the other. This means we will add 1 on both sides.

4y - 1 + 1 = 7 + 1

4y = 8

Remember how I mentioned we do the inverse of the operation? In this case, 4 is multiplying y. The inverse operation of multiplication is division. So, to get rid of the 4 - we must divide 4y by 4, on both sides.

4y / 4 = 8 / 4

y = 2

We now know the variable y is equal to 2.

Hopefully, this helps.

When 5655 is divided by a positive two digit intreger "N" the remainder is 11, when 5879 is divided by the same intreger N the r

Temka [501]

Answer:

Step-by-step explanation:

Hi,

When we divide 5655 by N, we get remainder of 11, which means that 5655-11 is a multiple of N.

5655 - 11 = 5644 is a multiple of N.

Similarly, 5879-14 should be a multiple of N.

5879 - 14 = 5865 is a multiple of N.

Because 5644 and 5865 are both multiples of N, their difference must be a multiple of N.

5865 − 5644 = 221 then 221 is a multiple of N.

We have three number of which N can be a multiple of, however we choose to factorize the smallest possible number amongst these three, which is 221. (This is only for simplification of the solution, smaller the number, less the factors)

221 : 1, 13, 17, 221.

There are only two two - digit factors: 13 and 17.

We divide 5865 and 5644 by both numbers.

$\frac{5865}{13} = 451.15 \\\frac{5865}{17} = 345 \\\frac{5644}{13} = 434.15 \\\frac{5644}{17} = 332\\$

Looking at these results, we know only 17 divides all three numbers.

Hence N=17.

The sum of both digits will be: 1 + 7 = 8
