what is x+2y=-2 -3x+2y=-1
also, I need show work so please if you can
Answer:
Point Form:
(-1/4, -7/8)
Equation Form:
x= -1/4, y= -7/8
Step-by-step explanation:
Answer:
x=-4, y=-6.5
Step-by-step explanation:
First, we need to find the value of x so
x+2=-2
-2 -2
x=-4
now plug the value of x, in the second equation
-3(-4)+2y=-1
12+2y=-1
minus 12 from both sides
12+2y=-1
-12 -12
2y=-13
divide by 2 to get the value of y
y=-6.5

Answer:
The first one is 14.5 and the second one is that the decimal moves to the left every time a zero is added to the first number
Step-by-step explanation:
Answer:
1. 14.5
2. 100/5=20. If you move the decimal places for both numbers, it would be the same thing. 10 and 0.5 were moved one decimal place to the left so the answer is still 20.
Step-by-step explanation:
1.
14.5
3/43.5
-3
-------
13
-12
-------
15
Notice the decimal place of all the choices, they each match.
1. −2x + 6 = -16
2. -10 + 5x = -45
Can you help me?
Answer:
for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2
getting -2x/-2=-22/-2 then you simplify that and get x=11
and for the second one x=-7. first, you have to add 10 to both sides
(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7
Help,
what do i put in the blanks
can someone help me plz
Answer:
X=12
Step-by-step explanation:
Isolate the variable:
4x/4 = 48/4
Simplify:
X=12
Hope this helps!
Answer:
x = 12
Step-by-step explanation:
Step one: Inverse the equation to eliminate the coefficient*.
*The coefficient is the number or variable that multiplies another variable (associated with it). In this case, it is four that is the coefficient.
48/4 = 12
x = 12
Check for answer:
4*12 = 48
The answer is x = 12.

whats the measure of the angles (SHOW YOUR WORK so I can understand)
Answer:
Angle DEB: 52
Angle ADB: 30
Angle CBE: 52
Angle BEC: 38
Step-by-step explanation:
Angle DEB = 52 because triangles' angles must add up to 180. Angle ADB is 30 because it is complementary to angle BDE. Angle CBE is 52 because angle BEC is complementary to BED which is 52 degrees to BEC is 38 degrees. since the angles add up to 180, and C is 90, CBE is 52. Finally, BEC is 38 because it is complementary to BED.

Two of the lowest temperatures ever recorded in the U.S. are -79.8 *F in Alaska and -69.7*F in Montana. Write an inequality that compares the temperatures.
Answer:
During cool or cold weather episodes, fuel must be consumed to make buildings comfortable living spaces. A useful indicator of fuel consumption for heating purposes is the determination of heating degree-days. They are calculated by accumulating one heating degree-day (HDD) unit for each Fahrenheit degree the daily mean (average) temperature is below the base value of 65°F (18°C). For example, a day with a maximum temperature of 60°F and a minimum of 40°F has a mean temperature of 50°F. Subtracting 50 from 65 yields 15 heating degree-day units for that day. Hence, a day with a high temperature of 45°F and a low of 25°F produces ______ HDDs.
