Answer:
J. 9
Step-by-step explanation:
First we have to plot the points (In the picture)
Now we have to count how close the are together which would make it 8.
And the closest to that would be 9.
Hope this helps :)
Answer:
Step-by-step explanation:
The distance between two points is
d^2=(x2-x1)^2+(y2-y1)^2
We have points (-4,-6) and (4,4) so
d^2=(-4-4)^2+(-6-4)^2
d^2=8^2+10^2
d^2=64+100
d^2=164
d=12.8
So H 13 units is closest to the distance between the two points.

Simplify! (The lesson is Exponents and Polynomials)
Answer:
a^4b^3/2
Step-by-step explanation:
Answer:
the simplify version is a^16 b^3
Calculate the value
of the unknown
coefficient b of a
quadratic equation
when the
discriminant of that
equation is known.
3x² + bx + 2 = 0; Coefficient = 12
Answer:
The value of b is either + 6 or -6
Step-by-step explanation:
Here, given that we have the value for the discriminant, we want to calculate the value for the coefficient of x
mathematically, the discriminant can be calculated using the equation;
D = b^2 - 4ac
a represents the coefficient of x^2 which is 3
b represents the coefficient of x given as b
2 represents the last number
D is the discriminant = 12
So we have that;
12 = b^2 - 4(3)(2)
12 = b^2 - 24
b^2 = 24 + 12
b^2 = 36
b = √36
b = +6 or -6

In a class of 147 students, 95 are taking math (M), 73 are taking science (S), and 52 are taking both math and science. What is the theoretical probability of randomly choosing a student who is taking math? Round your answer to the nearest tenth.
Answer:
The correct answer is 64.6%
Step-by-step explanation:
95 student total are taking a math class out of 147 kids. 95/147 = 0.646, carry the decible and you get your percentage which is 64.6%
-11y = 6(2+1) - 13y
4y - 24 = c(z – 1)
For what value of c does the above system of linear equations in the variables y and z have
infinitely many solutions?
Answer:
12
Step-by-step explanation:
Let's put the equations in standard form. For the first equation, we have:
−11y=6(z+1)-13y
2y−6z=6
y−3z=3
The second equation is:
4y−24=c(z−1)
4y−cz=24−c
If we multiply the first equation by 4, we get:
4y-12z=12
Comparing the two equations, we see that if c=12, both equations will be the same and there will be infinitely many solutions.
The correct value of c is 12.

The sum of the
First n terms of a linear
sequence is
ce is
[tex]2 - 7 {n}^{2} [/tex]
, find the second term
Answer:
-21
Step-by-step explanation:
Given the sum of the first n term as;
Sn = 2 - 7n^2
The nth term is expressed as;
Tn = Sn - Sn-1
Sn-1 = 2 - 7(n-1)^2
Tn = 2 - 7n^2 - (2 - 7(n-1)^2)
Tn = -7n^2 + 7(n-1)^2
To get the second term, we will substitute n = 2 into the resulting expression
T2 = -7(2)^2 + 7(2-1)^2
T2 = -7(4)+7(1)^2
T2 = -28 + 7
T2 = -21
Hence the second term of the sequence is -21

Jim ate 50 cookies yesterday. He ate 3 boxes of cookies and 8 cookies. How many cookies were in each box?
Answer:
Step-by-step explanation:
3b+8c=50c
3b=50c-8c
3b=42c
b=14c
So there are 14 cookies in each box.
Answer:
14
Step-by-step explanation:
First, take away the 8 cookies that were not part of the 3 boxes.
(50 - 8 = 42)
Now we know that 3 boxes of cookies can hold 42 total cookies. However, we need to know how much cookies 1 box can hold. If the 42 cookies are divided evenly between the 3 boxes, our equation would look like this:
42/3 = 14
Therefore, the answer is 14 cookies in each box.

1. Area of rectangle
A = l*z
2. Find z
93 = 13*z
z ≈ 7.15
Answer:
7km
Step-by-step explanation:
The given figure is a rectangle
The formula to find area of rectangle is,
[tex]l \times b[/tex]
Here,
Length = 13km
Area = 91 km^2
Then breadth = 91/13
= 7 km

Math please help give u brainlist
Answer:
C
Step-by-step explanation:
(0,-4) (-4, -3)
-3- -4 / -4 -0 = 1/-4 is the slope
so is C
Answer:
The answer is B.
Step-by-step explanation:
slope-intercept form is y=mx + b with m being slope and b being y-intercept. slope is change in y over change in x, and in this situation the change in y is 1 and the change in x is 4. so, slope = 1/4. so now our equation is y=1/4x+b. now we have to find the y-intercept, which in this graph is -4. so, the equation is y=1/4x+-4. Hope this helps!

The area of a bookmark is 140 square centimeters. The perimeter is 54 centimeters. What are the dimensions of the bookmark?
Answer:
See explanation
Step-by-step explanation:
Recall that all the sides of the square are equal
Hence;
Area of a rectangle= l * b ------- equation 1
Perimeter of a rectangle = 2(l + b)----------equation 2
Area of the rectangle = 140 square centimeters
140 = lb
l = 140/b
Perimeter of the rectangle = 54 centimeters
substituting l = 140/b into equation 2
54 = 2(140/b + b)
Multiplying through by b
54b = 280 + 2b^2
Hence;
2b^2 - 54b + 280 = 0
Solving the quadratic equation
b=20 or b=7
substituting b=20 or b=7 into l = 140/b
l = 140/20 or l = 140/7
l = 7 or 20
THEREFORE;
b=20 cm or b=7 cm
l = 7cm or 20cm
