Answer:

(y + 6)(y - 4)

Step-by-step explanation:

Factor the following:

[tex] \longrightarrow [/tex] y² + 2y - 24

The factors of -24 that sum to 2 are 6 and -4.

So,

[tex] \longrightarrow [/tex] y² + (6 - 4)y -24

[tex] \longrightarrow [/tex] y² + 6y - 4y - 24

[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)

[tex] \longrightarrow [/tex] (y + 6)(y - 4)

Answer:

( y-4) ( y+6)

Step-by-step explanation:

= y^2 + ( 6 - 4)y - 24

= y^2 + 6y - 4y - 24

= y( y + 6) - 4(y + 6)

= ( y - 4 ) ( y + 6)

The standard unit for the measurement of power is known as: B. Watts.

Measurement is a process through which the size, magnitude or other physical quantities that are associated with an object is taken, especially for the purpose of a scientific research (experiment).

In Science, some of the standard unit of measurements with the correct physical quantities include the following:

In conclusion, we can deduce that Watts is the standard unit for the measurement of power.

x=2.5

5x=17

x=3.4

then your equations

Answer:

  use the slope formula

Step-by-step explanation:

Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.

  m = (y2 -y1)/(x2 -x1)

For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...

  (hours, miles) = (1, 25) and (2, 75)

The corresponding slope on that interval is ...

  m = (75 -25)/(2 -1) = 50 . . . . miles per hour

__

You can identify four (4) regions on this graph in which the slope is constant:

  (0, 1) . . . slope is 25 mph

  (1, 2) . . . slope is 50 mph, as computed above

  (2, 3) . . . slope is 0 (the rider has stopped)

  (3, 5) . . . slope is 25 mph

Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

Answer:

$2.19

Step-by-step explanation:

Given that :

Cost of 3 pounds of grape = $6.57

Cost in dollars = y ; number of pounds = x

Cost in dollars α number of pounds

Cost in dollars = k * number of pounds

k = constant of proportionality

$6.57 = k * 3

$6.57 = 3k

Divide both sides by 3

6.57 / 3 = 3k/ 3

2.19 = k

k = $2.19

Answer:

x = 43

Step-by-step explanation:

lines were parallel, then 143 would have to congruent to the vertical angle of 3x + 14

this means that 143 would have to be congruent to 3x + 14

so we can set the equation to 3x + 14 = 143

subtract 14 from both sides: 3x = 129

divide both sides by 3: x = 43

principal = $3350

Step-by-step explanation:

principal = interest / (rate x time)

principal = 50.25 / 0.015

principal = 3350

Answer:

60 degrees.

Step-by-step explanation:

Do you see those red points on the lines? Those red arrows indicate that the lines are parallel, meaning, when there's a line crossing through two parallel lines, are vertical and adjacent angles are the same.

In this case, 11x-6 is equal to 10x.

11x-6 = 10x

-6 = -1x

divide -x both sides, you get x = 6.

Now you know that 11x - 6 = 60, because 11x - 6 = 10x, and since x = 6, 10x = 60.

---------------------------------------------------------------------------------------------------------

Since 10x is on a straight line, the angle next to it adds up to 180, so...

10x + y = 180.

We know that 10x = 60, so 60 + y = 180.

subtract both sides by 60, you get y = 120.

Now, you solved the whole graph.

Answer:

Step-by-step explanation:

ΔABC is congruent with ΔDEF.  That means the corresponding sides are congruent.

Look at the order of the letters.  EF are the last two letters of ΔDEF.  So this corresponds with the last two letters of ΔABC.  Therefore, EF ≅ BC.

EF ≅ BC

x² + 8x = 48

x² + 8x − 48 = 0

(x + 12) (x − 4) = 0

x = -12 or 4

Since x can't be negative, x = 4.
