11x - 16 = -49
x = _____
Answer:
x = -3Step-by-step explanation:
Given,11x - 16 = -49
=> 11x = - 49 + 16
=> 11x = -33
[tex] = > x = \frac{ - 33}{11} [/tex]
=> x = -3 (Ans)
Answer:
x=-3
Step-by-step explanation:
1. Add 16 to both sides of the equation
11−16=−49
11−16+16=−49+16
2. Simplify.
IF you add the numbers you will get:
11x=-33
3. Divide both sides of the equation by the same term
11=−33
11/11=−33/11
4. Simplify.
x=-3

A rainbow is an arc of colors that is visible in the sky, caused by the refraction and dispersion of light after rain or other water droplets in the atmosphere .The colours of the rainbow are generally said to be red
Answer:
Red, orange, yellow, green, cyan, blue and purple.
Step-by-step explanation:
The rainbow is a colorful visual and meteorological phenomenon, in which the range of colors that compose the visible light in the sky appears. The phenomenon occurs when the sun's rays fall on raindrops in the Earth's atmosphere and is an example of refraction, after reflection. Each color is refracted at a different angle inside the droplets (which act like small prisms), it undergoes a different deflection and so the visible white light is analyzed in the different colors that compose it.

what is the slope of y=-4x-8
Answer:
-4
Step-by-step explanation:
y = mx + b
Answer:
-4
Step-by-step explanation:
y=mx+b
m is slope
b is y-intercept
So you line y=mx+b and y=-4x-8
-4 is replacing m so -4 is the slope

Aaron is playing a game in which he earns points for a correct answer and loses the same number of points for an incorrect answer. Aaron has zero points. The next question is worth 300 points. Aaron says "It doesn't matter whether I get the answer right or wrong, the absolute value of my score will be 300." Do you agree? Why or why not?
Answer:
You should agree.

The absolute value if by definition "the magnitude of a real number without regard to its sign" this means if he earns 300 points on the next question. Yes Aaron's absolute value of points would be 300.
The total cost, c, of belonging to two different gyms for m months is shown on the graph. The lines intersect at the point (4,250). Enter numbers in the boxes to explain what the solution means in the situation.
Answer: at 4 months the cost for each gym is $250
Step-by-step explanation:
At 4 month, the cost for each gym is $250
The y axis of the graph represents the membership cost and the x axis represent the number of month.
The lines representing gym A and B intersect at (4, 250).
The point where the lines intersect is when the cost and the month for each gym are the same.
Therefore, at 4 month, the cost for each gym is $250

Point D is in the interior of ∠ABC. What is m∠DBC?
37.5 degrees
we know angled like this always have 180 degrees total between the 2. which means we can set up a little equation to solve for x. The equation is (3x+22)+(x-4)= 180. Initially we can take the solid numbers (22 and -4) and get rid of them by taking them to the 180. 180- 22 is 158. 158 + 4 is 162. now we have 3x + x = 162. we combine like terms. means we end up with 4x =162. We now divide by 4 which means we get 40.5. Now we know x is 40.5. Now dbc is just 40.5- 4 which is 37.5.
The measure of angle ∠DBC is,
⇒ ∠DBC = 35.5°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Point D is in the interior of ∠ABC.
And, ∠ABD = (3x + 22)°
⇒ ∠DBC = (x - 4)°
Clearly, Both angle make a linear pair.
Hence, We get;
⇒ ∠ ABD + ∠DBC = 180°
⇒ (3x + 22) + (x - 4) = 180°
⇒ 3x + 22 + x - 4 = 180
⇒ 4x + 18 = 180
⇒ 4x = 180 - 18
⇒ 4x = 162
⇒ x = 162/4
⇒ x = 40.5
Hence, The measure of angle ∠DBC is,
⇒ ∠DBC = (x - 4)°
⇒ ∠DBC = (40.5 - 4)°
⇒ ∠DBC = 35.5°

Answer:
7.5
Step-by-step explanation:
The square has 4 equal sides, so you take the p,(30) and divide it. 30/4 = 7.5
To check your answer add 7.5 four times since the square has 4 equal sides.
7.5 + 7.5 = 15
15 + 7.5 = 22.5

x - 9 = 21
What does x =
Answer:
x=30
Step-by-step explanation:
You have to isolate for x. This means you need to somehow get x on one side of the equation all alone. In this case it is x-9=21 which means some unknown number x with 9 subtracted from it is equal to 21. When we bring the -9 over to the other side to get the x all alone, we have to switch the sign of the -9 so it becomes +9. This means x=21+9, and if you add that you'll get 30!

Use slope formula to find slope:
7-4/2-1 = 3/1 = 3
M (slope)= 3x
Answer:
y=3x+1
Since we know that the line is increasing by 3 and since when x is equal to zero, and y is equal to 1 we know that we will need to add 1.
So Y=3x+1
