Answer:

y = -4x + 4

Step-by-step explanation:

y = (1/4)x - 1

m = (1/4)

Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/4)

                                                                      [tex]= (-1)*\frac{4}{1}\\\\=-4[/tex]

(3 , -8)

y - y1 =m(x -x1)

y -[-8] = -4(x - 3)

y + 8 = -4x + 12

    y = -4x + 12 - 8

    y = -4x + 4

Answer:

The way I was taught to do it is to change value into a total fraction, then multiple the numerators together, multiply the denominators together, and finally reduce as far as possible.

7/9 x 5 2/5 = 7/9 x 27/5 = 189/45 = 4 9/45 = 4 1/5

1 3/4 x 4 1/6 = 7/4 x 25/6 = 175/24 = 7 7/24

Answer:

a² + b² = 17

a^4 + b^4 = 257

Step-by-step explanation:

The only solutions for a+b=5 and ab =4 is:

4 and 1 but we don't know which is which. In this case it doesn't matter though.

a² + b² = 16 + 1 = 17

a^4 + b^4 = 256 + 1 = 257

can you answer my latest post plsssssss id appreciate it

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) All the sides are equal. So it is an equilateral triangle. SO, all the angles are equal

x = 60

2) In this triangle, two sides are equal. so, it is an isosceles triangle.

In isosceles triangle, angles opposite to equal sides are equal

x = 74

Answer:

El 40.75% de los alumnos del centro docente estudian matemáticas.

Step-by-step explanation:

Dado que el 35 % de los estudiantes de un centro docente practica el fútbol, y el 70 % de los que practican el fútbol estudia Matemáticas, así como el 25 % de los que no practican el fútbol, para determinar los porcentajes de estudiantes de matemáticas en el centro docente se debe realizar el siguiente calculo, suponiendo que el total de alumnos del centro sea 100:

35 x 70 / 100 = 2,450 / 100 = 24.5%

100 - 35 = 65

65 x 25 / 100 = 1,625 / 100 = 16.25%

24.5 + 16.25 = 40.75

Así, el 40.75% de los alumnos del centro docente estudian matemáticas.

In context of the problem, -40 means that 40 was the difference between the actual data, and the estimated data.

Step-by-step explanation:

Here -40 represent the difference between the actual data and the estimated data.

Given that,

Based on the above information we can say that the -40 shows the difference of data.

Given:

The figure of a right angle triangle.

To find:

The value of x.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

Using this formula in the given triangle, we get

[tex]\tan (31^\circ)=\dfrac{x}{33}[/tex]

[tex]0.60086=\dfrac{x}{33}[/tex]

[tex]0.60086\times 33=x[/tex]

[tex]19.82838=x[/tex]

[tex]x\approx 19.83[/tex]

Therefore, the value of x is about 19.83 units.

Answer:

y=−8

Step-by-step explanation:

−7y+4=60

Subtract 4 from both sides.

−7y=60−4

Subtract 4 from 60 to get 56.

−7y=56

Divide both sides by −7.

y=−56/7

Divide 56 by −7 to get −8.

y=−8

Grapf if needed:

Answer:

Step-by-step explanation:

Typically in a line the y intercept is the point where your graph crosses the y-axis, and the x value is 0 so (0,b) is the y-intercept where y-intercept is b

The slope can be found by finding the rate of change, so the change in y / the change in x

You can also calculate the slope with 2 points so (x1, y1) (x2, y2)

you take the y values and subtract them, then divide by the x values like this:

y2 - y1 / x2 - x1

If a line is going up to the right in Quadrant I then the slope is positive, if the slope of the line goes down in Quadrant IV  then the line slope is negative

Slopes of horizontal lines are zero, the slope of a vertical line is undefined

We use the letter m to stand for the slope

Answer:

y = 9/2 (fraction)

Step-by-step explanation:

y = mx+c

m = slope

c =y -intercept

Therefore, the required equation is:

y = 2x + c

Putting the point (0,4) in it as it lies on a line, we get:

4 = -1/2 + c

Therefore:

c = 9/2

So, y = 9/2

Answer:

x = 60

Step-by-step explanation:

So, ever triangle, no matter what shape or size, is always going to equal 180 degrees. You start off by trying to find angle L which is 71. The way you find this is you subratch 109 from 180 which ultimately gives you 71.

180 - 109 = 71

After that you have to add what you already have (49 degrees) with what you just found (71 degrees)

49 + 71 = 120

Now that you have 120, you have to again subtract 180 by 120 to get your answer, 60 degrees. And that's it.

180 - 120 = 60

Answer:

no solutions

Step-by-step explanation:

12x+15=12x

Subtract 12x from each side

12x-12x+15=12x-12x

15 = 0

This is not a true statement so there are no solutions

Answer:

The number of pounds that will fit in each bag is 2/3 pounds of flour

Step-by-step explanation:

Here, we want to know the amount of pounds that will fit in each bag

What we have to do here is to divide the total number of pounds of flour, by the number of bags filled

We have this as;

2 3/4 divided by 4 1/8

This is;

11/4 divided by 33/8

= 11/4 * 8/33 = 2/3 pounds

Answer:

200 cm (or 2 meters) or 80% of the original 250 cm is left.  let me know if you have any questions.  

Step-by-step explanation:

I'm not sure if that's asking for an exact amount or percent, so I will do both.

The trick either way is to match units.  we have meters and centimeters.  You could make either one match the other.  so 2.5 m is 250 cm and 50 cm is .5 m.

You do have to know how many centimeters is in a meter, but once you know that you can set up unit conversions, which are super simple.

there are 100 cm in a m.  a unit conversion is basically a fraction that cancels out units.  starting with 2.5 m we want to cancel out m so the fraction we use has the m part in the denominator.  so 2.5m * (100 cm)/(1 m).  (100 cm)/(1 m) is the unit conversion, and just like variables the m in the denominator cancles out the m in the starting value so it turns into 2.5 * 100 cm/1 = 250 cm.

similarly to go from 50 cm to meters you make the unit conversion have cm in the denominator.  so 50 cm * (1 m)/(100 cm) = .5 m.  again, the cm int he denominator cancels out the cm in the unit being multiplied.  Let me knwo if this is still not clear.

Anyway, now we have the numbers we need.  let's make them all cm, I think using the smallest unit is usually easiest.  so that's 250 cm total and 50 cm used.

In pure numbers, that means 200 cm is left (which is 2 meters) after 50 cm gets used.

percents is a little trickier.  if 250 is 100% then 50 is 20%, which you can get by doing 50/250.  if you do not know, a fraction a/b gives you the percent a is of b.  Or rather it gives you a decimal, and if you multiply it by 100 it gives you the percent.

anyway, if 20% is used then 80% is left.  if you did 200/250 you would get that.
