Answer: -11
Step-by-step explanation:
+(-8) can be simplified to -8 because when you multiply a positive sign by a negative sign, the outcome is a negative sign. So your problem is -3-8= and the answer is -11 because when two numbers with the same sign are subtracted/added by each other, the numbers just get added and the sign stays the same. If you're still confused, use a number line. Hope this helps!

When given points (1,1) and (2,2), what is the slope ?
Answer:
[tex]m=1[/tex]
Step-by-step explanation:
Slope can be calculated using following formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] ----------- (1)
Here
[tex](x_1, y_1)=(1, 1) \ \ and \ \ (x_2, y_2) = (2, 2)[/tex]
Substitute values in equation (1)
[tex]m=\frac{2-1}{2-1}[/tex]
[tex]m=1[/tex]
A company rents out 11 food booths and 28 game booths at the county fair. The fee for a food booth is $200 plus $9 per day. The fee for a game booth is $95 plus $6 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Step-by-step explanation:
Total company pay
= Pay for food booths + Pay for game booths
= 11($200 + $9d) + 28($95 + $6d)
= $2200 + $99d + $2660 + $168d
= $4860 + $267d
= $3(1620 + 89d).
Mario compared the slope of the function graphed below to the slope of the linear function that has an x-intercept of 1 and a y-intercept of -2
Answer:
The slope of the function graphed is less than the linear function that has an x-intercept of 1 and a y-intercept of -2.
Step-by-step explanation:
It is given that x-intercept is 1 and y-intercept is -2.
Now, the coordinate of the point is (1,0) and (0,-2).
We know that,
Slope = [tex]\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]S_1=\dfrac{-2-0}{0-1}[/tex]
[tex]S_1 = \dfrac{-2}{-1}[/tex]
[tex]S_1=2[/tex]
Now, Slope of the graph given
Co-ordinate is (-5,0) and (1,2).
Using the formula of slope
[tex]S_2 = \dfrac{2-0}{1-(-1)}[/tex]
[tex]S_2 = \dfrac{2}{1+1}[/tex]
[tex]S_2 = \dfrac{2}{2}[/tex]
[tex]S_2 =1[/tex]
Now, [tex]S_1>S_2[/tex]
Hence, the slope of function graphed is less than linear function that has an x-intercept of 1 and a y-intercept of -2.

Find the distance on the map, in cm, which represents an actual distance of 14.4 km
Answer:
14.4 km = 1440000
Step-by-step explanation:
1 km = 1000m
14.4 km = 1000 ×14.4
=14400 m
1 m =100 cm
14400 m = 100 × 14400
= 1440000 cm

11. Find mZJHI.
Answer:
JHI = 23°
Step-by-step explanation:
Since it's a rectangle it has 4 right angles.
90= 3x + 2 + 12x -17
90= 15x -15
105= 15x
x=7°
So HJI would be 12*7 -17 = 67°
Knowing that the sum of the angles of a triangle is 180°,
67° + 90°+ JHI= 180°
JHI = 23°
Answer:
Step-by-step explanation:
we have 2 equations that we can set equal to 90. that way, we can find x and then solve the equations for themselves. angle JHI is equal to GJK, which is an angle we can easily find. here is my work:
(3x + 2) + (12x - 17) = 90
15x - 15 = 90
+ 15 + 15
15x = 105
x = 7
3(7) + 2
21 + 2
GJK = 23
so, since the two angles are congruent, that means that angle JHI = 23 degrees

Answer:
Ratios are proportional if both serve the identical tie. A method to detect if a pair of ratios remain equivalent is to rewrite them being fractions, then decrease them. If the decreased fractions are equal, the ratios are comparative.

2v + 18 = 16 - 4(v + 7)
please help, thank you
Answer:
v=−5
Step-by-step explanation:
2v + 18 = 16 - 4(v + 7)
2v+18=16−4(v+7)
2v+18=16+(−4)(v)+(−4)(7)(Distribute)
2v+18=16+−4v+−28
2v+18=(−4v)+(16+−28)(Combine Like Terms)
2v+18=−4v+−12
2v+18=−4v−12
Add 4v to both sides.
2v+18+4v=−4v−12+4v
6v+18=−12
Subtract 18 from both sides.
6v+18−18=−12−18
6v=−30
Divide both sides by 6.
6v /6 = −30 /6
v=−5

Lupe and her friends spend $20 on hot dogs and popcorn at a
sporting event. Hot dogs cost $2.50 each, and popcorn costs $1.00
each. They buy a total of 11 items at the concession stand. How
many of each item do they buy?
Answer:
They buy 6 hotdogs and 5 popcorn
Step-by-step explanation:
Assume that they buy x hotdogs and y popcorn
∵ They buy a total of 11 hotdogs and popcorn
∵ The number of hotdogs is x and the number of popcorn is y
∴ x + y = 11 ⇒ (1)
∵ Hot dogs cost $2.50 each
∵ Popcorn costs $1.00 each
∵ They spend $20 on hot dogs and popcorn
→ Multiply x by 2.5 and y by 1, add the products and equate the sum by 20
∴ 2.5(x) + 1(y) = 20
∴ 2.5x + y = 20 ⇒ (2)
Now we have a system of equations to solve it
→ Subtract equation (1) from equation (2)
∵ (2.5x - x) + (y - y) = (20 - 11)
∴ 1.5x + 0 = 9
∴ 1.5x = 9
→ Divide both sides by 1.5 to find x
∴ x = 6
→ Substitute the value of x in equation (1) to find y
∵ 6 + y = 11
→ Subtract 6 from both sides
∴ 6 - 6 + y = 11 - 6
∴ y = 5
∴ They buy 6 hotdogs and 5 popcorn
When solving a system of equations of A and B, we get no solution. When solving B and C, the solution is (0,3). When solving A and D, the solution is the origin. When solving B and D, the solution is (-1.5, 1.5). What is the solution when solving A and C? What are the equations of all the lines?
Answer:
You know that when solving B and c it is 0,3 and you know that when solving A and D the solution is the origin. Also when solving b and d it is -1.5,15 so D equals 1.5 and A equal the origin so solve from their

help me with the Quadratic equation.... x2+ (p - 5) x + 2q = 0 has the roots −3 and 6. Find the value of P and the value of q.
Step-by-step explanation:
The quadratic equation is x² + (p - 5)x + 2q = 0.
By Vieta's Formula,
we have SOR = -b/a and POR = c/a.
=> (-3) + (6) = -(p - 5) and (-3)(6) = 2q.
=> 3 = 5 - p and -18 = 2q
Hence, p = 2 and q = -9.
Alternate Method:
We have (x + 3) and (x - 6) as factors of the quadratic equation x² + (p - 5)x + 2q = 0.
=> (x + 3)(x - 6) = x² - 3x - 18.
By Comparing Coefficients,
(p - 5) = -3 and 2q = 18.
Hence p = 2 and q = -9.

John is measuring a piece of glass to fit in a triangular frame. He can only remember
two sides of the frame, which are 6 centimeters and 11 centimeters. Between what
two numbers must the third side of the frame fall?
A. X < 17

Matthew has a jar of 368 nickels and dimes he has been collecting. The total value of the coins is $28.40.Which system of linear equations and solution can be used to represent the number of nickels and dimes Matthew has in his collection?
A. n + d = 368 0.05n + 0.1d=28.4 168 nickels and 200 dimes
B. n + d = 368 0.01n + 0.05d=28.4 200 nickels and 168 dimes
C. n + d = 368 0.05n + 0.1d=28.4 200 nickels and 168 dimes
D. n + d = 368 0.1n + 0.05d=28.4 168 nickels and 200 dimes
Answer:
[tex]n + d = 368[/tex]
[tex]0.05n + 0.10d = 28.40[/tex]
Step-by-step explanation:
Given
[tex]Total = 368[/tex]
[tex]Value = \$28.40[/tex]
Required
Determine the linear equations to represent the scenario
Represent nickel with n and dimes with d
So, the total is:
[tex]n + d = 368[/tex]
[tex]1\ nickel = \$0.05[/tex]
[tex]1\ dime = \$0.10[/tex]
So, the value is:
[tex]0.05n + 0.10d = 28.40[/tex]
Hence, the linear equations are:
[tex]n + d = 368[/tex]
[tex]0.05n + 0.10d = 28.40[/tex]
The system of linear equations and solution can be used to represent the number of nickels and dimes Matthew has in his collection is n + d = 368 0.05n + 0.1d=28.4 168 nickels and 200 dimes.
Given that,
Matthew has a jar of 368 nickels and dimes he has been collecting. The total value of the coins is $28.40.Here we take n be nickles and d be dimes. Also, 1 nickel be = $0.05 and 1 dime be $0.10.Based on the above information, the calculation is as follows:
n + d = 368
So,
d = 368 - n
And,
0.05n + 0.10d = 28.40
0.05n + 0.10(368 - n) = 28.40
0.05n + 36.8 - 0.10n = 28.40
0.05n = 8.4
n = 168
So, d = 368 - 168
= 200
Therefore we can conclude that the correct option is A.
