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:
Step-by-step explanation:
“The area of a rectangular garden is 120 square meters.”
LW = 120
“The width is 4 meters longer than one-half of the length.”
W = 0.5L + 4
L = 2W-8
Substitution
(2W-8)W = 120
2W^2-8W-120 = 0
W^2 -4W-60 = 0
W = 10, -6
-6 is an extraneous solution.
W = 10 meters
L = 2W-8 = 12 meters
Manu enjoys throwing spaghetti on his days off. He stands in his backyard every Saturday afternoon, the equation of his throw and How high is the spaghetti went is mathematically given as
y=-10/3x^2+22x-68/3
x=0
<h3>What is the equation of his throw and how high is the
spaghetti went?</h3>
Generally, the equation for the three sceneario equations are is mathematically given as
16a+4b+c=12(4,12)
4a+2b+c=8(2,8)
25a+5b+c4(5,4)
Now solving the matrix we have
a=-10/3
b=22
c=-68/3
Therefore, the equation is
y=ax^2+bx+c
y=-10/3x^2+22x-68/3
In conclusion, considering his throws starting point
s=-68/3, -ve show below the surface and with time as zero
x=0
