Answer:
This second number line is called an integer number line, since integers are the set of numbers including all whole numbers and their negative opposites. Two opposite numbers are the same distance from zero on the number line, but on opposite sides. For example, 3 and -3 are opposites.

What is the y-intercept of the line given by the equation y=5x+16 ?
Answer:
16
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is the slope
b is the y-intercept
-----------------------
y = 5x + 16
is in slope intercept form
b, the y-intercept is 16
which is point (0, 16)

Answer:
1) -⅓
2) -6
3) infinite
4) 4
Step-by-step explanation:
slope = y/x
1) -1/3 = -⅓
2) -6/1 = -6
3) 1/0 = infinite
4) 4/1 = 4
Answer:
1:
(0,-1) and (3,-2)
slope=(y2-y1)/(x2-x1)=(-2+1)/(3-0)=-⅓

Answer:
The answer is A=2/9 yards²
Step-by-step explanation:
The formula for a rectangle is A=B x H
So the equation is A= 1/3 yards x 2/3 yards

at food mart, hot dogs can be purchased in packages of 8 for $2.40 or packages of 12 for $3.00. which is a better buy? explain how you know HELP
Answer:
12-hot dog package is better buy because the per hot dog price is 5 cents cheaper
Step-by-step explanation:
2.40/8 = 0.30 per hot dog
3.00/12 = 0.25 per hot dog (this is the better buy by $.05)
Answer:
12-hot dog package per hot dog price is 5 cents cheaper
Step-by-step explanation:
= 2.40/8 = 0.30 per hot dog
= 3.00/12 = 0.25 per hot dog (this is the better buy by $.05)

B Reading Choose the best estimate for the multiplication problem below. 85 x 86
A. 8100
B. 10,400
C. 12,200
Answer:
A. 8100
Step-by-step explanation:
85 x 86
To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.
85*100 = 8500
Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.

Answer:
7. 75.36 inches
8. 21 inches
9. 13 inches
Step-by-step explanation:
7. Circumference = π × d
The diameter would be two times the radius, or 2 × 12 = 24. So, circumference would be 3.14 × 24 = 75.36 inches.
8. Circumference = π × d
If we move variables around, d = Circumference / π
So, d = 65.94 / 3.14 = 21 inches.
9. To do this, let's figure out the diameter: d = Circumference / π
d = 81.64 / 3.14 = 26. Now the diameter is two times the radius, so to get the length of the radius, we must divide the diameter in half. 26 / 2 = 13 inches.
Terry finished cooking at 7:36 p.m. She cooked for 2 hours and 40 minutes. What time did she start cooking?
Answer:
2:56 pm
Step-by-step explanation:
end time: 7:36 pm
Borrow one hour from the hours and add it as 60 minutes to the minutes.
7:36 pm = 6:96 pm
Now subtract 2:40 from 6:96.
Subtract 2 from 7 and subtract 40 from 96.
7:36 pm - 2:40 = 6:96 pm - 2:40 = 2:56 pm
Answer: 2:56 pm
Let 0 be an angle such that sec0= -13/12 and cot0<0. Find the exact values of tan0 and sin0.
Answer:
tan 0 = -2.4
sin 0 = 0.42
Step-by-step explanation:
sec 0 = -13/12 => cos 0 = -12/13
cot 0 < 0 => tan 0 < 0
so, the angle is on second quadrant
=> tan 0 = -12/5 = -2.4
=> sin 0 = 5/12 = 0.42
Answer:
Solution given;
Sec θ=-[tex]\frac{13}{12}[/tex]
cotθ< 0,
It lies in second quadrant.
where sin and cosec is positive.
Now
[tex] \frac{1}{cosθ}=-\frac{13}{12}[/tex]
cosθ=[tex]\frac{12}{13}[/tex]
[tex]\frac{b}{h}[/tex]=[tex]\frac{12}{13}[/tex]
b=12
h=13
By using Pythagoras law
p=[tex] \sqrt{13²-12²}=5 [/tex]
Now
exact values of tan θ=[tex]\frac{p}{b}[/tex]=[tex]\frac{5}{12}[/tex]
since it lies in II quadrant
tan θ=-[tex]\frac{5}{12}[/tex]
and
sinθ=[tex]\frac{p}{h}[/tex]=[tex]\frac{5}{13}[/tex]
since it lies in II quadrant
sin θ=[tex]\frac{5}{13}[/tex]

What is the measure, in degrees, of angle b?
The top angle is the same as the bottom angle, since they are vertically opposite angles.
b+20=40
b=40-20
b=20
It is also 20 degrees.
Answer:
Step-by-step explanation:
angle b+20 degree=40 degree(being vertically oppoite angles)
angle b=40-20
angle b=20
therefore angle b=20 degree.

Chau rented a truck for one day. There was a base fee of $18.95, and there was an additional charge of 95 cents for each mile driven. Chau had to pay $198.50
when he returned the truck. For how many miles did he drive the truck?
Let's say John drove 2 miles. He had to pay the base fee of $18.99 and $.75(2) = $1.50, so he paid $20.49 total.
We are given his total, though, and asked to find the mileage.
18.99 + .75m = 199.74
-18.99 -18.99
.75m = 180.75
.75 .75
m = 241
So, John drove 241 miles.
Hope this helps!

What is the range of possible sizes for side x?
Answer:
x = 3.96
Step-by-step explanation:
To find the missing side length you'll need the formula a^2 + b^2 = c^2
a and b would be the shorter ends, 2.8 and 2.8
c would be the longer end that's opposite the right angle.
so substitute values
2.8^2 + 2.8^2 = c^2
7.84 + 7.84 = c^2
15.68 = c^2
√15.68 = √c^2
3.959797 = c
c = 3.96
side c would be side x so x is 3.96

Suppose that you are interested in the relationship between the return rate on a stock in 2010 compared to the return rate in 2009.-You believe that the return rates in both years are positively correlated. A sample of 15 stocks'yields the following regression results: b0=5.3, b1= 1.04, sb= 1.79, and MSE = 35.4. 1:79, sb= 0.2163, R2 = 0.64
i. How would you explain the slope coefficient b1?
ii. What is the least squares regression line?
iii. What is the predicted value of y when x = 5
iv. Calculate the error sum of squares.
v. Calculate the total sum of squares.
vi. Calculate the regression sum of squares.
vii. Prepare the analysis of variance table for regression.
Step-by-step explanation:
1. we have b1 = 1.04 which is positive. we say that the return I. 2009 is positively correlated with the return in 2010.
2. Y = b0 + b1X
Y = 5.3 + 1.04X
3. If x = 5
Y = 5.3 + 1.04(5)
Y = 10.5
4. SSE = mse x (n-2)
n = 15, mse = 35.4
SSE = 35.4 x(15-2)
= 35.4 x 13
= 460.2
5. We are to find SST here
R² = SSR/ SSR + SSE
R² = 0.64
SSE = 460.2
0.64 = SSR/SSR+460.2
Cross multiply
0.64(SSR + 460.2) = SSR
0.64ssr + 294.528 = SSR
Collect like terms
294.528 = SSR - 0.64SSR
294.528 = 0.36SSR
SSR = 294.528/0.36
SSR = 818.13
SST = SSR + SSE
= 818.13 + 460.2
= 1276.53
6. The SSR has been calculated to be 818.13

If I had 36 apples what is the percentage of 20
Answer:
20 apples is 55.55% of 36 apples.
Step-by-step explanation:
Given that I had 36 apples, to determine what is the percentage of 20 of them, the following calculation must be performed:
36 = 100
20 = X
(20 x 100) / 36 = X
2000/36 = X
55.55 = X
Therefore, 20 apples is 55.55% of 36 apples.

Sum of 4x^3+6x^2+2x^2-3 and 3x^3+3x^2-5x-5 is
9514 1404 393
Answer:
7x^3 +11x^2 -5x -8
Step-by-step explanation:
Combine like terms.
(4x^3+6x^2+2x^2-3) + (3x^3+3x^2-5x-5)
= (4 +3)x^3 +(6 +2 +3)x^2 +(-5)x + (-3 -5)
= 7x^3 +11x^2 -5x -8
_____
Noting that the first expression contains two x^2 terms, we wonder if you actually want the sum ...
(4x^3+6x^2+2x-3) + (3x^3+3x^2-5x-5)
= (4 +3)x^3 +(6 +3)x^2 +(2 -5)x +(-3 -5)
= 7x^3 +9x^2 -3x -8
