Solve for m 3-2(9+2m)=m

Mathematics
1 answer:
tester [92]3 years ago

Answer:

m=-3

Step-by-step explanation:

3-2(9+2m)=m

3-2(9)-2(2m)=m

3-18-4m=m

-15-4m=m

-15=m+4m

5m=-15

Divide by 5

5m/5=-15/5

m=-15/5

m=-3

To check if correct, subsitute m for -3 in the equation. And both sides of the equation must be equal

3-2(9+2m)=m

3-2(9+2(-3))=-3

3-2(9-6)=-3

3-2(3)=-3

3-6=-3

-3=-3

X^2+20x+c find the value of c that makes a perfect square trinomial
ollegr [7]

Answer:

This means c=100. The factored form is (x+10)^2.

Step-by-step explanation:

A perfect square is a trinomial that factors into the form (x+a)^2. To find the value of C to finish the perfect square divide 20 by 2 and square it.

20/2 = 10

10*10=100

This means c=100. The factored form is (x+10)^2.

Which ordered pair is a solution of the system?
kenny6666 [7]
Y = -2x - 4

x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5

y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6

Solution set {-5, 6} (C)

FIST ONE TO AWNSER AND CORRECT GETS BRAINLYIST AND 50 POINTS HURRY!!!!!!!!!!!!
ANEK [815]

Answer:

D

Step-by-step explanation:

It is because you can see the line pass through the value 0 in x-axis while 6 in y-axis which gives the first coordinate (x,y) = (0,6) and the line also past through the value of 5 in x-axis and 1 in y-axis which gives the second coordinate is (1,5).

So it is true that the line did go through at points (0,6) and (1,5).
