Answer:
<5
Step-by-step explanation:
exterior angles + the corresponding interior angle of the triangle = 180º or a straight angle
the only exterior angle shown in the diagram is <5, which corresponds to the interior <2
hope this helps!
Answer:
y = 2x + b (the second answer choice)
Step-by-step explanation:
The slope-intercept form is y = mx + b (the m representing slope and the b representing y-intercept). Put the points in ratio form as a fraction and subtract the ratio with the smallest numbers from the ratio with the largest ratio (5/1 - 1/-1) to get 4/2. When simplified, it becomes 2/1, so the slope is 2. Using the slope found previously, subtract 1 from the x of (1, 5) and 2 from the y of (1, 5) to get the y-intercept. The resulting point is (0, 3), so the y-intercept is 3. Replace the m with the found slope (2) and b with the found y-intercept (3) to end up with y = 2x + 3.
To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.
16 - 12x = 4y
First, divide both sides by 4. / Your problem should look like: \frac{16-12x}{4} = y
Second, factor out the common term 4. / Your problem should look like: \frac{4(4-3x)}{4} = y
Third, cancel 4. / Your problem should look like: 4 - 3x = y
Fourth, switch sides. / Your problem should look like: y = 4 - 3x
Answer: y = 4 - 3x
