Hippalectryon Points U, V, and W are plotted on a number line. The coordinate of point V is –2. Points U and W are the same distance from point V.

What could be the coordinates of U and W?

A.
U = –11, W = 7

B.
U = –8, W = –6

C.
U = –6, W = 6

D.
U = 0, W = 2

Answers

Checking answer A:
distance from U to V = -2-(-11)=9
distance from U to W =7-(-2)=9 -> same distance !

checking answer B:
distance U-V : -2-(-8)=6
U-W : -2-(-6)=4 -> not the same distance

answer C :
U-V : -2-(-6)=4
U-W : 6-(-2)=8 -> not the same distance

answer D :
U-V : 0-(-2)=2
U-W : 2-(-2)=4 -> not the same distance

Conclusion : answer A

D. 0, 20 is 2 away for -22 is 4 away from -2
C -6, 6-6 is 4 away from -26 is 8 away from -2
You have to find out which two points are the same distance from -2.

How can I solve this system of linear equations by substitution 2x-3y=-24 and x+6y=18

Answers

to sub
solve for 1 variable
solve for x
minus 6y both sides on second equotn

x=18-6y

sub 18-6y for x in other equation
2(18-6y)-3y=-24
36-12y-3y=-24
36-15y=-24
minus 36 oth sides
-15y=-60
divide -15 both sides
y=4

sub back

x=18-6y
x=18-4(4)
x=18-16
x=2

x=2
y=4

There were 21 students in Travis's fourth-grade class at the end of the year. During the year four new students joined his class, and two moved away. One student was transferred to another fourth-grade teacher. How many students were there in the beginning of the year?

Answers

so there were 21 students from the start then 4 new people joined so 21 plus 4 equals 25 . 25 minus 2 equals 23 23 minus 1 equals 22

You start with 21 then add 2 as 2 moved away 21+2=23 1 student was transferred add that on 23+1=24 At the begging of the year there were 24 students.

Which strategies can be used to solve this problem? The population of Grayville is 2,345 people. Rosetown has 1,123 fewer people than Grayville. Newtown has 1,020 more people than Rosetown. How many people live in Newtown? Choose all answers that are correct. A. Translate into an equation. 2,345 – 1,123 + 1,020 = p B. Work backward. Add 1,020 to the population of Rosetown (1,123). Subtract this from the population of Grayville (2,345). C. Use logical reasoning. Start with the population you already know (Grayville = 2,345). Subtract Rosetown's 1,123 fewer people than Grayville. Add 1,020 to this amount because Newtown has 1,020 more people than Rosetown. D. Draw a diagram. Draw 3 large circles. Write 2,345 in the first circle and write 1,123 in the second circle. Add the 2 amounts and subtract 1,020 from the sum. Write this amount in the third circle.
