Answer:
equation in slope intercept form: y = 2x +1
Step-by-step explanation:
given coordinates = (2,5) and (3,7)find slope,m = (y2 - y1) / (x2 - x1)= (7 - 5) / ( 3 - 2)
= 2
using the formula: y - y1= m( x - x1 ): y = 2x +1
equation in slope intercept form:
[tex]y = 2x +1[/tex]
given coordinates:
[tex](2,5) and (3,7)[/tex]
find slope,m:
[tex]\frac{y2 - y1}{x2-x1}= \frac{7-5}{3-2} = 2[/tex]
using the formula:
[tex] y - y1= m(x-x1) : y-5=2(x-2)[/tex]

( GIVING BRAINLY) How can 10% of 64 be used to determine 40% of 64? Enter your answers in the boxes to correctly complete the statement. 10% of 64 is , so 40% of 64 is .
Answer:
It can be used to figure it out because you will multiply the 10% by 4 and you'll get 40 percent.
Step-by-step explanation:
Please mark brainliest
Answer:
You can determine by adding the percentage up. See down below.
Step-by-step explanation:
64 x 10% = 6.4
40% will mean 6.4 x 4 which equals 25.6
40% = 25.6
10% = 6.4
10% of 46 would be 4.6.

Answer:
867.Step-by-step explanation:
Given equation:
800 + 60 + 7Solve:
800 + 60= 860 + 7= 867.Answer:
[tex]\huge\boxed{867}[/tex]
Step-by-step explanation:
6 tens is the equivalent of 6 * 10, or 60
8 hundreds is the equivalent of 8 * 100, or 800
7 ones is the equivalent of 7 * 1, or 7.
Simply add these numbers to get that 60 + 800 + 7 = 867

Based upon your visual analysis of the "Average MPG" histogram, what is the most appropriate measure of center and variation to calculate and interpret?
The most appropriate measure of center and variation to be computed and interpreted in this case is the Mean and Standard Deviation measures.
The appropriate measure of center and variationThe shape of a distribution is the factor that decides the most appropriate measure of century and variation which will be calculated as well as interpreted. In this case, the histogram is normally distributed, hence the need to use Mean and standard deviation.
Other types of distributionOther types of distribution are indicated as follows:
The complete options in the question to select from are:
A) The mean and standard deviation
B) The median and interquartile range
C) The median and Standard Deviation
D) The mean and Interquartile range.
The correct answer is A.

If The area of the circle is 64 to the power of 2 pi what is the circumference
Answer:
C=401.92
Step-by-step explanation:
the equation for area of a circle is A=r^2 pi so if the area of this circle is A=64^2 pi, then we can see that 64 is the radius of the circle.
(A=r^2 pi
A=64^2 pi so r=64)
So if the radius is 64, then the diameter is (because diameter is double the radius) Then we use the newfound diameter and plug into the equation for Circumference of a circle which is
C=d pi
C=128 (3.14)
so C=401.92

What is the surface area of the prism in square inches? A rectangular prism has a height of 2 inches, width of 8 inches, and depth of 11 inches.
The surface area of a rectangular prism is given by:
A = 2 * (x * y) + 2 * (x * z) + 2 * (y * z)
where,
x, y, z: are the sides of the rectangular prism
Substituting values we have:
A = 2 * (2 * 8) + 2 * (2 * 11) + 2 * (8 * 11)
A = 252 in ^ 2
Answer:
The surface area of the prism in square inches is:
252 square inches
Answer:

Find the function value, if possible. (If an answer is undefined, enter UNDEFINED.)
f(x) =
−5x − 5, x < −1
x2 + 2x − 1, x ≥ −1
(a)
f(−4)
(b)
f(−1)
(c)
f(1)
Answer:
(a) 15
(b) -2
(c) 2
Step-by-step explanation:
For each given value of x, determine the applicable function definition and use that to determine the function value.
(a)-4 is less than -1, so the first function definition applies:
f(-4) = -5(-4) -5 = 20 -5
f(-4) = 15
__
(b)-1 is equal to -1, so the second function definition applies:
f(-1) = (-1)^2 +2(-1) -1 = 1 -2 -1
f(-1) = -2
__
(c)1 is greater than -1, so the second function definition applies:
f(1) = (1)^2 +2(1) -1 = 1 + 2 -1
f(1) = 2
Jason made the following calculations. Explain the errors Jason made. Give the correct answers.

Answer:
a. 1/3+3/5 =14/15
b. 11/12 - 5/6 =1/12
Step-by-step explanation:
The error in number 1 is the that the L.C.M of 3 and 5 is 15 and not 8.
In number 2, I think Jason didn't look for the L.C.M before he solved.

A rectangular room is 15 meters longer than it is wide, and it’s perimeter is 26 meters. Find the dimensions of the room
Answer:
the room is -1m by 14m
Step-by-step explanation:
what you do to find it is first find x.
the perimeter is 26, and one side is 15 meters longer than the other(twice).
So the equation is:
x + (x + 15) + x + (x + 15) = 26
2x + 2(x + 15) = 26
2x + 2x + 30 = 26
4x + 30 = 26
26 - 4x = 30
26 - 26 - 4x = 30 - 26
-4x = 4
-4x/-4 = 4/-4
x = -1
Now we have two sides of the room. Now we want the 15m longer ones...
-1 + 15 = 14
so the dimensions are -1 by 14, or -1x14

walk to school: 18%
close to school: 11/50 = 22/100 = 22% . . . (greater than 18%)
The portion of students who live within 1/2 mile of school is greater than the portion who walk to school.
_____
Additional comment
The % symbol essentially means /100.
Then 18% = 18/100 = 9/50. The fraction 11/50 is greater than this.
