Answer:
slope: 3
y-intercept: 1
slope-intercept form equation: y = 3x + 1
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
the equation you're given, 10 = 3(3) + b, is already in slope-intercept form and also already has the slope identified (it's 3!) so thankfully that's one less thing to solve for! :)
all you have to do now is solve for b.
first, multiply 3(3).
10 = 3(3) + b
10 = 9 + b
then subtract 9 from both sides of the equation. 9 and -9 cancel each other out, so the only thing you have to do for this step is subtract 9 from 10.
10 - 9 = b
1 = b <em>aka</em> b = 1
and now you have your b value!
so your slope is 3 and your y-intercept is 1.
i hope this helps! have a nice rest of your day <3
Answer:
X<3
Will be ur answer i guess .
angle 2 = 114°
supplementary angles sum to 180° thus
5y + 16 + 10y + 14 = 180
15y + 30 = 180
subtract 30 from both sides
15y = 180 - 30 = 150
divide both sides by 15
y = = 10
angle 1 = (5 × 10) + 16 = 50 + 16 = 66° and
angle 2 = (10 × 10) + 14 = 100 + 14 = 114°
Answer: x=-3
Step-by-step explanation:
move -9 over to -12 and the 9 becomes positive and then add -12+9 and your answer will be negative
|2x-3|=2x-1
need to consider two cases
(1) 2x-3<0 --> x<3/2
-(2x-3)=2x-1
x=1, and this is <3/2 so that's a valid solution
(2) 2x-3>=0 --> x>=3/2
2x-3=2x-1
-3 = -1 so there no solution for x>=3/2
The single solution is x=-1
