Answer:
y = x + 3 or y = 1x + 3
Step-by-step explanation:
Since we're just going to find the equation (assuming it's slope-intercept form, which is <em>y = mx + b</em>), our jobs will be relatively simple!
Let's start with the first step and identify the y-intercept, which is the easiest step.
That will be (0,3), as the line intercepts the y-axis there.
Next, let's find the slope of the line using or . Just be careful when using that you correctly identify the scale the axis' are using.
For now, I'll use . Let's pick two points... (0,3) and (1,4).
—> =
This will be our slope, 1.
We now have our answer, y = 1x + 3.
Hope that helped!
It will get smaller unless the term is lower than negative 1
Answer:
[-6,-3]
Step-by-step explanation:
So we have the compound inequality:
Let's solve for each of the inequalities:
1)
We have:
Subtract x from both sides:
Subtract 7 from both sides:
So that's one of our answers.
2)
We have:
Subtract 3x from both sides:
Subtract 4 from both sides:
Divide both sides by -2. Since we're dividing by a negative, flip the sign:
Therefore, our entire answer is:
This means all values in between -3 and -6 including -3 and -6.
In interval notation, this is:
So, A is -6.
And B is -3.
And we're done :)
Answer:
50° and 130°
Step-by-step explanation:
∠1 is a chord- chord angles and is calculated as
∠1 = 0.5( arc RQ + arc ST) = 0.5(53 + 47)° = 50°
∠1 and ∠2 form a straight angle and are supplementary, hence
∠2 = 180° - 50° = 130°
