You would insert -1 into the x and take 3 times -1 which is -3 minus 1 which is -4. Helpful?

Y = 3x - 1 when x = -1
When the problem tells you what x is, put it into the problem:
y = 3(-1) -1
Solve the parentheses:
y = -3 -1
Now do the rest of it:
y = -4

I hope this helped you <3

while swimming a 2km race, Adam changes from breaststroke to butterfly every 200m. How many times does he switch strokes during

aleksley [76]

in the first half he would have swam 1 km. there are 1000m in a km so 1000/200=5 so he swam the first 200 fly, then a 200 breast, then a 200 fly again, then another 200 breast the finish the first 1 km with a 200 fly. so we switched strokes 4 times.

PS i wouldn't recommend doing a 2 km swim fly and breast

The value of y in the triangle is 6°.

<h3>How to calculate the value of y in the triangle?</h3>

Firstly, it's important to note that a triangle has the total angles of 180°.

Based on the information, the triangle has interior angle measures of 11y, 10y + 10°, and 10y - 16º.

The value of y in the triangle will be illustrated thus:

11y + 10y + 10 + 10y - 16 = 180
