Step-by-step explanation:

=( n-2)180

= ( 4 - 2 )180

= 360

So, 144 + 90 + m<2 +m<1 = 360

144 + 90 + 85 + m<1 = 360

319 + m<1 = 360

m<1 = 360 - 319

m<1 = 41

their is an unknown angle so let's call it x

let's find x first ( m<6=49)

x + m<6 = 180

x + 49 = 180

x = 180 - 49

x = 131

Now let's find m<7

m<7 + 38 + m<4 + x = 360

m<7 + 38 + 85 + 131 = 360

m<7 + 254 = 360

m<7 = 360 - 254

m< 7 = 106

Answer:

Step-by-step explanation:

-2x - 14 > -4 + 3x

subtract 3x from both sides

-5x - 14 > -4

add 14 to both sides

-5x > 10

divide both sides by -5

x < -2

The answer would be -5x > 10.

This is because our last inequality was -5x - 14 > -4 so we add 14 to both sides and it would look like this -5x (-14 + 14) > (-4 + 14) which would transition into our next inequality -5x > 10.

So therefore the answer would be -5x > 10.

Answer:

x = 3

y = 2

Step-by-step explanation:

5x - 3 = 6y

5x + 3 = 9y

y = 5/6 x - 1/2

5x + 3 = 15/2 x - 9/2

-5/2 x + 15/2 = 0

-5/2 (x - 3) = 0

x = 3

Answer:

x = 3

y = 2

Step-by-step explanation:

because it's a rectangle, opposite sides are equal

AD = BC

AB = DC

so we can use their measures to create a system of equations:

5x + 3 = 9y

5x - 3 = 6y

if we multiply the first equation by -1 we can eliminate the x-values:

-(5x + 3 = 9y)

 -5x - 3 = -9y

+ 5x - 3 = 6y

        -6 = -3y

         y = 2

If y = 2 then BC = 12 and we can set up this equation:

12 = 5x - 3

15 = 5x

3 = x

Answer:

b is 135 and c is 45.................thanks

Answer:

[tex]b=135\\c=45[/tex]

Step-by-step explanation:

The angle that measures 135 degrees and angle b are opposite angles. Opposite angles are congruent. Therefore, angle b=135.

[tex]b=135[/tex]

A straight line has an angle measure of 180 degrees. This means that 135+c would equal 180 degrees.

[tex]135+c=180[/tex]

Subtract both sides by 135

[tex]135+c-135=180-135\\c=45[/tex]

8 * 8

Step-by-step explanation:

Power is the result of multiplying two numbers together. The correct option is 2×2×2×2×2×2, 4×16, and 8×8.

Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

The given expression can be written as,

2⁶ = 2 × 2 × 2 × 2 × 2 × 2

   = 4 × 16

   = 8 × 8

Hence, the correct option are 2×2×2×2×2×2, 4×16, and 8×8.

Answer:

Step-by-step explanation:

Answer:

1) Zero based on (-16·t - 2) is t = -1/8 second

2) Zero based on (t - 1) is t = 1 second

Step-by-step explanation:

The given functions representing the height of the beach ball the child throws as a function of time are;

y = (-16·t - 2)·(t - 1) and y = -16·t² + 14·t + 2

We note that (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2

Therefore, the function representing the height of the beachball, 'y', is y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2

The zeros of a function are the values of the variables, 'x', of the function that makes the value of the function, f(x), equal to zero

In the function of the question, we have;

y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2

The above equation can be written as follows;

y = (-16·t - 2) × (t - 1)

Therefore, 'y' equals zero when either (-16·t - 2) = 0 or (t - 1) = 0

1) The zero based on (-16·t - 2) = 0, is given as follows;

(-16·t - 2) = 0

∴ t = 2/(-16) = -1/8

t = -1/8 second

The zero based on (-16·t - 2) is t = -1/8 second

2) The zero based on (t - 1) = 0, is given as follows;

(t - 1) = 0

∴ t = 1 second

The zero based on (t - 1) is t = 1 second

The equation in the slope-intercept form will be:

Step-by-step explanation:

Given

Important Tip:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

In our case,

Step 1 of 2

Determine the y-intercept b

substitute m = -1/2 and (x, y) = (6, -4) in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]-4\:=-\:\frac{1}{2}\left(6\right)+b[/tex]

switch sides

[tex]-\frac{1}{2}\left(6\right)+b=-4[/tex]

[tex]-3+b=-4[/tex]

Add 3 to both sides

[tex]-3+b+3=-4+3[/tex]

simplify

[tex]b=-1[/tex]

Thus, the y-intercept b = -1

Step 2 of 2

substitute the values

substitute b = -1 and m = 1/2 in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]y=-\frac{1}{2}x+\left(-1\right)[/tex]

[tex]\:y=-\frac{x}{2}-1[/tex]

Conclusion:

Therefore, the equation in the slope-intercept form will be:

[tex]\:y=-\frac{x}{2}-1[/tex]

Answer:

$0.231

Step-by-step explanation:

Given data

P= $77

r= 16%

t= 6 months= 0.5 years

For simple interest

A= P(1+rt)

A=77(1+0.16*0.5)

A= 77(1+0.08)

A= 77*1.08

A= $83.16

For compound interest

A=P(1+r)^t

A= 77(1+0.16)^0.5

A= 77(1.16)^0.5

A= 77*1.077

A= $82.929

The difference is

=83.16- 82.929

=$0.231

Step-by-step explanation:

cosA = AC² + BC²- AB² / 2 • AC • BC

cos A = 13.5²+23.9²-12.7²/2• 13.5 • 23.9

Answer:

y = 25.8

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos y = adjacent/ hypotenuse

cos y = 18/20

Take the inverse cos of each side

cos ^-1 (cos y) = cos^-1(18/20)

y =25.84193276

Rounding to the nearest tenth

y = 25.8

Answer:

1.  144  2. 16 3. 1   4. 3x-6  

Step-by-step explanation:

So think of this as a function in a function.  So you work from the inside to the outside.  So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).  

Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]

so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)

So take the h(x) function which is h(x) = [tex]x^{2}[/tex] then h(12) = [tex]12^{2}[/tex] so h(12) = 144
