Answer:
y=2x+7
Step-by-step explanation:
We can substitute values x and y in the equations to see if it works in the equations.
For example, the first equation is y=-2x+6. Using the point (-3, 1), we know that 1 is the y value and -3 is the x value. So, 1 = -2(-3)+6
We can rearrange this is to get 1=12. This is false, so this can't be the right answer.
y=2x-1
1=2*-3-1 so 1=-7 which is also false
y=2x+7
1=2*-3+7 so 1=1 which is true!
We can use any of the points given to check that this equation works.
Hope this helps!
Answer:
y = 2x + 7
Step-by-step explanation:
Slope intercept form: y = mx + b
You will need to find the slope and y-intercept
First, find the slope: = y2 - y1 / x2 - x1
Given points: (-3, 1) (-2, 3)
m = 3 − 1 / −2 − −3
m = 2 / 1
m = 2
Slope is 2, now find the y-intercept
y = 2x + b (Use point (-3, 1))
1 = 2(-3) + b
1 = -6 + b
b = 7
Equation: y = 2x + 7

Answer:
Step-by-step explanation:
Circumference of a circle: C = 2*π*r
22/7 or π = 3.14
r (radius) = d/2
5. d/2 = 2
r = 10/2 = 5 cm.
C = 2*π*r
C = 2*3.14*5
C = 10*3.14
C = 31.4 cm.
6. r = 90 in.
C = 2*π*r
C = 2*3.14*90
C = 180*3.14
C = 565.2 in
7. r = 16 yd.
C = 2*π*r
C = 2*3.14*16
C = 32*3.14
C = 100.48 in
8. r = 4 in.
C = 2*π*r
C = 2*3.14*4
C = 8*3.14
C = 25.12 in.
9. d/2 = 2
r = 22/2 = 11 cm.
C = 2*π*r
C = 2*3.14*11
C = 22*3.14
C = 69.08 cm.
10. d/2 = 2
r = 4/2 = 2 m.
C = 2*π*r
C = 2*3.14*2
C = 4*3.14
C = 12.56 m.
11. In short words, a radius is half of its diameter. So a circle with a diameter of 8 cm has a radius of 4 cm because r = d/2. 8/2 = 4 cm.
Hope this helps!
Answer:
1. C = 31.4 cm. 2. C = 565.2 in 3. C = 100.48 in 4. C = 25.12 in. 5. C = 69.08 cm. 6. C = 12.56 m.

Answer:
Isosceles Trapezoid
Step-by-step explanation:
Please refer to the attached diagram I drew for visual representation.
Isosceles Trapezoid:
The top and bottom ("bases") are parallel to each other.Opposite, non-parallel sides are of the same length.Base angles are congruent.Adjacent angles on the non-parallel sides sum to 180°.Sum of interior angles is 360°.In triangle XYZ, the length of side XY is 25 mm and the length of side YZ is 39 mm. Which of the following could be the length of side XZ?
Answers
Answer:
The length of side XZ should be greater than 10 and lesser than 60.
Step-by-step explanation:
In triangle XYZ ,
As
The length of side XY = 25 mm
The length of side YZ = 35 mm
Range of the third side can be computed when we already know the two sides of the triangle.
If subtracting , the 3rd side would have to be more than 10. Else 3rd side can not be made as two smaller legs will not meet.
and
If adding , the 3rd side would have to be less than 60. Else 3rd side will reach further than the the other two sides could reach.
Therefore, the length of side XZ should be greater than 10 and lesser than 60.

3 1/3 - 1 1/4 = ____
Answers
Answer: 2 1/12
Step-by-step explanation: 3-1=2 and 1/3•1/4= 1/12
Answer: 9 1/12
3 1/3 - 1 1/4 is impossible to do right now. So we have to make a common denominator! The smallest common denominator is 12, since 3 x 4 is 12. So we need to multiply 3 1/3 by 4, which is 12 4/12. Now we have to multiply 1 1/4 by 3, which is 3 3/12. Now we can subtract!
12 - 3 = 9
4/12 - 3/12 = 1/12
9 + 1/12 is 9 1/12! Hope that helped!
