Graph of linear equation will be always straight line.

Number of ice cream cones sold be  76.

The relationship between the temperature (°F) and the number of ice cream cones sold is given by model,

                   [tex]y=1.8x-76.9[/tex]

Where x represent temperature and y represent number of ice cream cone sold.

 When temperature is  85°F  , it means that ,  x =  85°F

   So,    [tex]y=1.8*85-76.9\\\\y= 76.1[/tex]

Thus, number of ice cream cone sold is to be 76.

Answer:

y-(-8)=4(x-2)

Step-by-step explanation:

This is point-slope form. Point-slope form is y-y₁=m(x-x₁), this is y minus the change in y equals slope (slope is m) times x minus the change in x. An ordered pair is (x, y). You just plug in the missing values. This will get you y-(-8)=4(x-2). I hope this helps! Also, make sure not to put the parenthesis around -8 in the actual box! They are just there to make for less confusion.

Step-by-step explanation:

Answer:

The value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is 317.

Step-by-step explanation:

Let the system of nonlinear equations be:

[tex]x\cdot (y-1) = 180[/tex] (1)

[tex]y\cdot (1+x) = 208[/tex] (2)

From (1), we clear [tex]x[/tex]:

[tex]x = \frac{180}{y-1}[/tex]

Let apply this resulting expression in (2):

[tex]y\cdot \left(1+\frac{180}{y-1} \right)= 208[/tex]

[tex]y\cdot \left(\frac{y-1+180}{y-1} \right) = 208[/tex]

[tex]y\cdot \left(\frac{y+179}{y-1} \right)=208[/tex]  

[tex]y\cdot (y+179) = 208\cdot (y-1)[/tex]

[tex]y^{2}+179\cdot y = 208\cdot y-208[/tex]

[tex]y^{2}-29\cdot y+208 = 0[/tex]

By the Quadratic Formula we obtain the solution of the second order polynomial:

[tex]y_{1} = 16[/tex] and [tex]y_{2} = 13[/tex]

And the respective values of [tex]x[/tex] are, respectively:

[tex]y_{1} = 16[/tex]

[tex]x_{1} = \frac{180}{y_{1}-1}[/tex]

[tex]x_{1} = \frac{180}{15}[/tex]

[tex]x_{1} = 12[/tex]

[tex]y_{2} = 13[/tex]

[tex]x_{2} = \frac{180}{y_{2}-1}[/tex]

[tex]x_{2} = \frac{180}{12}[/tex]

[tex]x_{2} = 15[/tex]

If we know that [tex]x_{1} = 12[/tex], [tex]y_{1} = 16[/tex], [tex]x_{2} = 15[/tex] and [tex]y_{2} = 13[/tex], then the value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is:

[tex]f = 12+10\cdot (16)+15+10\cdot (13)[/tex]

[tex]f = 317[/tex]

The value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is 317.

The total amount of money is 65x + 10 cents.

Given the following coins value

x dimes, (x+2) nickels, and 2x quarters

If value of a dime is 10 cents, nickel is 5 cents, and a quarter is 25 cent, the the total coin is cent is expressed as 10x + 5(x + 2) + 25(2x)

Total in cents. = 10x + 5(x + 2) + 25(2x)

Total in cents = 10x + 5x + 10 + 50x

Simplify

Total in cents = 65x + 10

Hence the total amount of money is 65x + 10 cents.

Answer:

[tex] \fbox{A triangle can have 2 acute angles.}[/tex]

Step-by-step explanation:

Acute angle : The angle whose measure is less than 90° is called actute angle.

Obtuse angle : The angle whose measure is more than 90° is called obtuse angle.

Right angle : The angle whose measure is exact 90° is called right angle.

Property of triangle: The measure of all three angles of a triangle is 180°.

let's solve the actual question now,

Option A - let a triangle have two acute angle x and y respectively and z third angle of the respective triangle,

x + y + z = 180°

(<90°) + (<90°) + z = 180°

z = 180 - (<180)

z <180

the measure of 3rd angle z will be less than 180,

hence a triangle can have 2 acute angles.

Option B - let a right angle triangle have two right angles x and y respectively and z third angle of the respective triangle,

x+y+z = 180

90+90+z = 180

z = 180-180 = 0°

which means the third angle z does not exist and it is not a triangle. Hence a right angle triangle can only have one right angle.

Option C - let a triangle have two obtuse angle x and y respectively and z third angle of the respective triangle,

x + y + z = 180°

(>90°) + (>90°) + z = 180°

z = 180 - (>180)

when one number is subtracted from another number which is greater than that then the result obtain is negative. So the value of third angle z will be negative which is a flaw. Hence third option is also incorrect.

Option D - let a triangle have one right angle and one obtuse angle x and y respectively and z third angle of the respective triangle,

x + y + z = 180°

(90°) + (>90°) + z = 180°

z = 180 - (>180)

Same as option C, the third angle is negative which is a flaw and this option is incorrect too.

Conclusion- A triangle can have 2 acute angles and one right angle. So option A is the correct match.
