The equation for the line of best fit is y=2x+2.5. Soon, Edmond is going to a new fair. Use the equation for the line of best fit to predict how many tickets he could purchase for $12.50.
Answer:
x = 5
Step-by-step explanation:
The equation of a line is given by :
y=2x+2.5
Where
y is cost and x is number of tickets
Put y = $12.5 in the above equation
So,
12.5=2x+2.5
10 = 2x
x = 5
So, he can purchase 5 tickets.
Vanessa has $200 in her savings account and
just received $30 for her birthday. She intends
to spend all of her money on coffee. She spends
$3.50 on coffee every day. Write an equation
that can be used to find the amount of money she
has left after x days.
Answer:
y = -3.5x + 230
Step-by-step explanation:
Find how much money she has now:
200 + 30 = $230
To create an equation to find how much money she has left, let y represent the amount of money left, and x represent the number of days.
Coffee will cost $3.50 every day, so 3.5x will represent all of the money that she will spend on coffee.
The amount of money she has left will be represented by 230 - 3.5x.
Rearrange this to put x in front, and let this equal to y to create the equation:
y = -3.5x + 230
So, the equation that can be used to find how much money she has left is y = -3.5x + 230

13.At the Finch School bake sale, donuts sell
for $2 each muffins sell for $3 each. A
combined total of 104 donuts and muffins
are sold, resulting in $243 in sales. Which
of the following statements must be true?
a. 69 more muffins were sold than donuts.
b. 34 more muffins were sold than donuts.
c. 34 more donuts were sold than muffins.
d. 69 more donuts were sold than muffins.
Answer:
c)
Step-by-step explanation:
create a system of equations:
d + m = 104
2d + 3m = 243
now use substitution method based on 'd = 104 - m'
2(104 - m) + 3m = 243
208 - 2m + 3m = 243
208 + m = 243
m = 35
So, 35 muffins and 69 donuts were sold.
This is 34 more donuts than muffins.

Answer:
E) C and D. is the answer to ur q
a line that passes through (4,5) and (0, -12)
Answer:
Step-by-step explanation:
Hello : let A(4,5) B(0,-12)
the slope is : (YB - YA)/(XB -XA)
(-12-5)/(0-4) = 17/4
an equation is : y=ax+b a is a slope
y = (17/4)x +b
the line through point B(0,-12) : -12 = (17/4)(0)+b
b =-12
the equation is : y =(17/4)x-12

Meteor Crater, located near Flagstaff, Arizona, is a circular
crater with a circumference of 2.32 miles. What is the
approximate diameter of the crater?
Answer:
The approximate diameter of the crater is 0.74 mile.
Step-by-step explanation:
Circumference of a circle(C)=2*π*r(radius of the circle)
2.32 miles=2π*r
or, r=2.32 miles/2π
So, r=0.369 mile
Then,
d=2r
d=2*0.369 mile
So, d= 0.74 mile
Explain why the formula A = 1/2 ( bh ) works for finding the area of a triangle
Answer: It works because a triangle is half of a square and when you divide by two it helps because It is half of a square, the base x height works well because since we do base times height for parallelograms and it works the same for a triangle since this it is a parallelogram this is why A=1/2( bh ) works for finding the area of a triangle. let me if this helped or not.

How can you break up the figure into familiar shapes to determine the area?
A figure is broken into a triangle and rectangle. The rectangle has a base of 5 feet and height of one-third feet. The triangle has a base of 3 and two-thirds feet and height of 2 feet.
Break up the figure into a 2 ft by 3 and two-thirds ft triangle and a 5 ft by One-third ft rectangle.
Break up the figure into a 2 ft by 5 ft triangle and a 5 ft by One-third ft rectangle.
Break up the figure into a 2 ft by One-third ft triangle and a 5 ft by One-third ft rectangle.
Break up the figure into a 2 ft by 1One-third ft triangle and a 5 ft by One-third ft rectangle.

What is the solution of the system of equations? y = 25x + 100; y = -10x +
30 *
O A. (2,50)
O B. (-2, 10)
C. (-2, 50)
O D. (2,150)
Answer:
B(-2, 10)
Step-by-step explanation:
-10x+30=25x+100
subtract 25 from -10 (make it -25)
-35x+30=100
subtract 30 from 100 (make it -30)
-35x=70
divide by -35
x=-2
Plug it in:
-10(-2)+30
-20+30
y=10
What is the value of x in the diagram of Circle O below? *
Answer:
60 degrees
Step-by-step explanation:
As we know that a circle is 360 degrees, and as line AB bisects the circle, then the resulting "semi-circle" is 180 degrees. As we know that angle AC is 120 degrees, it's simple subtraction, to find that 180-120 is 60. Therefore, the value of x must be 60 degrees.

5. If the dimensions of a rectangle are doubled, which of the following best describes an effect on the rectangle?
Answer:
Since length and width are perpendicular, Doubling either one will double the area. So Doubling both will quadruple the area. 2x2 = 4.
This idea works if the dimensions doubled are those that are used to compute area. Like the base and height of a triangle.
More generally, in a polygon, if all the sides are doubled, the area is multiplied by 4. In a circle, Doubling the radius will quadruple the area.
In 3 dimensions, Doubling one dimension will double the VOLUME. Doubling two perpendicular dimensions will quadruple the volume and Doubling 3 perpendicular dimensions will multiply the volume by 2x2x2 or 8.

If I went to the store in a boat on a boat how cold was it true or false.
Answer:
Any temp less than 70 degrees is dangerous. So really, probably the worst thing about cold weather boating is the danger if you fall in. If it's really cold and you are bundled up, you don't have as much flexibility. If you have gloves on, you can't get the same grip.

Solving the following system using the elimination of substitution method.
5a+3b=11
-2a+3=b
Answer:
a = -2
b = 7
Step-by-step explanation:
5a+3b=11
-2a+3=b
substitute for b:
5a + 3(-2a + 3) = 11
5a -6a + 9 = 11
-a = 2
a = -2
b = 7
8. For angle A it is known that cos(A)<0 and csc(A)=10. If A is drawn in standard position, in which
quadrant does its terminal ray lie?
Answer:
The second quadrant.
Step-by-step explanation:
If cos A is negative it is in either QII or QIII.
If csc is positive so is the sine so its in QI or QII.
So to satisfy both conditions the answer is QII.
