3x-y=-1 and -3x+4y=-14

Mathematics
1 answer:
Natali [406]3 years ago
3 0
I'm not sure what we're being asked to find here but if this is putting the equation into slope-intercept form, then it's:

3x - y = -1

-y = -3x -1

y = 3x - 1

And

-3x + 4y = -14

4y = 3x - 14

y = 0. 75x - 3.5


But if you're asking to solve this as systems of equations then:

3x - y = -1

-3x + 4y = -14

Solving by elimination. Add both equations together.

3x - y = -1
+ -3x + 4y = -14
———————————
3y = -15

Divide both sides by 3.

y = -5

Now that we know the numerical value of y, we can solve for x.

3x - y = -1 -3x + 4y = -14

3x - (-5) = -1 -3x + 4(-5) = -14

3x + 5 = -1 -3x - 20 = -14

3x = -6 -3x = 6

x = -2 x = -2


So, the solution/coordinates to these system of equations are (-2, -5).

When the point (-1,3) is dilated with the center of dilation at the origin, the image of the point is (4,-12). What is the scale
Elina [12.6K]

Answer:

-4

Step-by-step explanation:

When the dilation center is the origin, the dilation factor is the ratio of dilated coordinates to original coordinates: 4/-1 = -12/3 = -4.

7. Compare the value of the 5 in 85,327 and 435.
Colt1911 [192]

Answer:

5 in the 85327= five thousand units

5 in the 435= five units

Step-by-step explanation:

85,327= eighty five thousand, three hundred and twenty seven

Value of five or the position if five in the above number is the thousand position

5 in the above = five thousand unit

435= four hundred and thirty five

The position of five in the above number is the unit position

Five in the above= five unit

Find the complete factored form of the polynomial -24a6b4-40a3
Naddik [55]

For this case we have the following polynomial:

-24a ^ 6b ^ 4-40a ^ 3

We must find the greatest common factor of the terms of the polynomial.

The GCF of the coefficients is given by:

24 = 3 * 8\\40 = 5 * 8

Then we look for the GFC of the variables:

We have then:

a ^ 6 = a ^ 3a ^ 3\\a ^ 3 = a ^ 3

Finally rewriting we have: -24a ^ 6b ^ 4-40a ^ 3 = -8a ^ 3 (3a ^ 3b ^ 4 + 5)

Answer:

the complete factored form of the polynomial is:

-8a ^ 3 (3a ^ 3b ^ 4 + 5)

Can anybody help this question?
Oxana [17]

Answer:

the first option

Step-by-step explanation:

really, just look at the table.

is the mean value (10.4) larger than the median (13.4) ?

I hope you can see right away that it is not.

and you can see they are not the same either.

so, all the answer options mentioning mean larger than median or equal to median can be ruled out right away.

so, it is between the first two options.

now think ! how do we draw number lines ? a coordinate axis ?

the smaller numbers left, the larger numbers right. the numbers grow from left to right.

the mean value is simply the sum of all measurements divided by the number of measurements (how many median were done). if that is smaller that the median (so, the Mean is left of the Median), it means that the majority of measurements had a result smaller (to the left) than the Median. so, it is skewed-left.
