The vertices of quadrilateral MNPQ are M(−3,−2),N(−1,4),P(2,4), and Q(4,−2). Translate quadrilateral MNPQ using the vector ⟨3,−4⟩.
Answer:
M'(0,-6),N'(2,0),P'(5,0) and Q'(7,-6)
Step-by-step explanation:
We are given that the vertices of quadrilateral MNPQ are M(-3,-2),N(-1,4),P(2,4) and Q(4,-2).
We have to translate the quadrilateral MNPQ using vector <3,-4>
The translate the coordinates of vertices (x,y) using the vector <a,b> is given by the rule
[tex](x,y)\rightarrow (x+a,y+b)[/tex]
Using the rule
The new coordinates of M
[tex](-3,-2)\rightarrow (-3+3,-4-2)[/tex]
[tex](-3,-2)\rightarrow (0,-6)[/tex]
The new coordinates of N
[tex](-1,4)\rightarrow (2,0)[/tex]
The new coordinates of P
[tex](2,4)\rightarrow (5,0)[/tex]
The new coordinates of Q
[tex](4,-2)\rightarrow (7,-6)[/tex]
Hence, after translation the new vertices of quadrilateral are
M'(0,-6),N'(2,0),P'(5,0) and Q'(7,-6)

Answer:
x = 43.5°
Step-by-step explanation:
The sum of the angles around a point = 360°
sum the angles and equate to 360
x + x + 72 + 111 + 90= 360
2x + 273° = 360° ( subtract 273° from both sides )
2x = 87° ( divide both sides by 2 )
x = 43.5°
Answer:
Sum of the angles around a given point is 360°.
[tex]x + x + 72 + 90 + 111 =360 \\ 2x + 273 = 360 \\2x = 360 - 273 \\ 2x = 87 \\ x = \frac{87}{2} \\ \boxed{x = 43.5°}✓[/tex]

Rectangle FGHJ has diagonals FH and JG that intersect at M. If FJ=−3x+5y, FM=3x+y, GH=11, and GM=13, find the values of x and y. Explain your answer.
Answer:
x=3 y=4
Step-by-step explanation:
-3x + 5y = 11
+ 3x + y = 13
Add the equation (add the 5y and y. Then add the 11 and 13). The threes cancel each other out. It then leaves us with the equation:
6y = 24
Divide both sides by 6 to isolate the variable.
y=4.
Then just substitute the variable into any of the equations above. (I chose the equation on top)
-3x + 5(4) = 11
Then solve
-3x + 20 = 11 (then subtract 20 from both sides)
-3x = -9 (then divide both sides by -3)
x=3

Solve 7+2x over 3 = 5
Please and thank you! x
Answer:
x = 4
Step-by-step explanation:
(7 + 2x) / 3 = 5
Cross product
7 + 2x = 5 * 3
7 + 2x = 15
Subtract 7 from both sides
2x = 15 - 7
2x = 8
Divide both sides by 2
x = 8/2
x = 4

Step-by-step explanation:
The volume of a pyramid is equal to the area of the base times height divded by three so
[tex]V = \frac{A_{base} h }{3} \\V = \frac{(8^{2})(11.5) }{3} \\V = \frac{736}{3} \\V = 245\frac{1}{3} in^{2}[/tex]

Find the equation of the straight line passing through the points (–2, 3) and parallel to y=2x-1
Answer:
[tex]y=2x+7[/tex]
Step-by-step explanation:
All parallel lines have the same slope, so in slope intercept form, our line is going to look like
[tex]y=2x+b[/tex]
To find b, we can plug in the x and y values from the given point (-2, 3) and solve:
[tex]3=2(-2)+b\\3=-4+b\\b=7[/tex]
So our equation becomes
[tex]y=2x+7[/tex]
everyday finn brushes his teeth 3 times , for 2 min each time , he flosses twice a day , for 5 minutes each time. In a year , how much time does finn spend brushing and flossing his teeth?
Answer:
5,840 minutes
Step-by-step explanation:
Assuming there are 365 days in a year. If finn brushes his teeth 3 times , for 2 min each time then the time spent to brush his teeth in a day
=3 * 2 minutes
= 6 minutes
If he flosses twice a day , for 5 minutes each time, then the time spent in a day to floss
= 2 * 5 minutes
= 10 minutes
Hence total time spent in a day brushing and flossing
= 6 + 10
= 16 minutes
Hence the time spent in a year brushing and flossing
= 16 * 365
= 5,840 minutes

Answer:
x=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x+4x−68=34−8x
5x+4x+ −68=34+ −8x
(5x+4x)+(−68)=−8x+34(Combine like terms)
9x+−68=−8x+34
9x−68=−8x+34
Step 2: Add 8x to both sides.
9x −68+ 8x= −8x +34 +8x
17x −68 =34
Step 3: Add 68 to both sides.
17x −68 +68= 34 +68
17x=102
Step 4: Divide both sides by 17.
17x /17= 102/17
X=6 > final answer hope i could help :)
Step-by-step explanation:
Let's step through this line by line, looking for a spot where the friend could have made a mistake.
[tex]5x+4x-68=34-8x\\5x+4x=102-8x\\5x+4x+8x=102\\17x=102\\x=6[/tex]
So, where could the friend have made their mistake? The key here is the transition from step 1 to step 2. What if we had subtracted 68 instead of adding it?
[tex]5x+4x-68=34-8x\\5x+4x=-34-8x\\5x+4x+8x=-34\\17x=-34\\x=-2[/tex]
There it is. The friend's problem was that they had accidentally subtracted 68 to both sides when they should have added it.

(-5, -1) is not a solution to the equation 2y = 2x - 4.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
2y = 2x - 4 _____(1)
Ordered pair: (-5, -1)
Now,
(-5, -1) = (x, y)
Substitute in (1)
2y = 2x - 4
2 x (-1) = 2 x (-5) - 4
-2 = -10 - 4
-2 = -14
This is not true.
Thus,
(-5, -1) is not a solution.
