Answer:

The answer is: 2x^2-7x-2

Step-by-step explanation:

we are asked to subtract 7x-9 from 2x^2-11

so, 2x^2-11-(7x-9)\\=2x^2-11-7x+9\\=2x^2-7x-2.

Hence the desired result is:  2x^2-7x-2.

The space allowed for the mascot on a​ school's Web page is 75 pixels wide by 60 pixels high. Its digital image is 500 pixels wi
anzhelika [568]

Answer:

It will be 60 pixels high and 75 pixels wide

Step-by-step explanation:

\frac{400}{60}=\frac{500}{x}

As

  • The space allowed for the mascot on a​ school's Web page is 75 pixels wide by 60 pixels high
  • Its digital image is 500 pixels wide by 400 pixels high

So, the expression becomes

\frac{400}{60}=\frac{500}{x}

\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c

400x=60\cdot \:500

400x=30000

\mathrm{Divide\:both\:sides\:by\:}400

\frac{400x}{400}=\frac{30000}{400}

\mathrm{Simplify}

x=75

Therefore, it will be 60 pixels high and 75 pixels wide

choli [55]

Answer:

Step-by-step explanation:

x+y=10

x=10-y

x=10-5

x=5

3y= -3x+30

3(10-y)= -3(10-y)+30

30-3y= -30+3y+30

30+30-30=6y

30=6y

y=5

What is the length of AC¯¯¯¯¯
Nutka1998 [239]

Answer: AC=12 cm

Step-by-step explanation:

To  solve this problem you must apply the law of sines, as you can see below:

\frac{a}{sinA}=\frac{b}{sinB}

Where:

a=13

A=85.2°

B=71.6°

Therefore, you must solve for b, then, you obtain that the lenght AC asked in the problem above is:

b={sinB}*\frac{a}{sinA}\\b=\frac{sin(71.6)*13}{sin(85.2)}\\b=12
