Answer:

\boxed {\sf m= -3}}

\boxed {\sf b= 4}

Step-by-step explanation:

The equation of the line is in slope intercept form or:

y=mx+b

where <em>m</em> is the slope and <em>b</em> is the y-intercept.

Essentially:

  • The coefficient to x, or number being multiplied is the slope
  • The number added or subtracted from the x term is the y-intercept

The line given is:

y= -3x+4

-3 is the coefficient of x and 4 is being added to -3x.

The slope (m) is -3 and the y-intercept (b) is 4.

Dans computer reads 68% of battery left after 1 hour. If the rate of using power remains the same, about how much longer will hi
Tanya [424]

Answer:

28 minutes

Step-by-step explanation:

Dans computer reads 68% of battery left after 1 hour. This means that 1 hour is 68% of the computer's entire battery life.

Let the entire battery life be x (in hours). Hence:

\frac{1}{x} * 100 = 68

Therefore:

\frac{100}{x} = 68\\\\x = \frac{100}{68}

=> x = 1.47 hrs = 1 hr 28 minutes

Hence, the entire battery life is 1 hr 28 minutes.

If 1 hour has elapsed, the remaining time left for his battery to provide power will therefore be:

1 hr 28 minutes - 1 hr = 28 minutes

His battery will provide power for 28 more minutes.

x=0

because you must

determine the undefined range

write all numerators above the common denomonator

multiply the parenthesis

collect the alike terms

remove parenthesis

eliminate the opposites collect the like terms

set the numerator equal to 0

divide both sides by 6

check if thesolution is the defined range

if so then you would find your answer X=0

How to find the area of each face of a prism
tatiyna

If the face is a square, then (l*l)

If the face is a triangle, then (b*h)(1/2)

If the face is a rectangle, then (l*w)

If the face is a circle, then (r²)(3.14)

You can then add all these faces up to get the total surface area of the prism.

I need help for this question.
sattari [20]

Answer:

B

Step-by-step explanation:

The figure is a trapezium with area (A) calculated as

A = \frac{1}{2} h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here h = 8, a = 10 and b = 6, thus

A = \frac{1}{2} × 8 × (10 + 6) = 4 × 16 = 64 cm² → B
