Step 2
Step-by-step explanation:
Michelle's step in trying to solve the equation is given below:
Michelle made a mistake in Step 2.
The right hand side of Step 1:
Rather, the correct sum is:
Answer:
x=8.06
Step-by-step explanation:
Since it's a right triangle, we can use Pythagorean Theorem, which is a^2+b^2=c^2. The hypotenuse, or longest side is always C, so in this case we're going to do C^2-a^2=b^2. 9^2=81, 4^2=16, 81-16=65, square root of 65 is 8.06, so x=8.06
Answer:
y = 5x - 27
Step-by-step explanation:
Given: point on a line (
5
,
−
2
)
with slope, m = 5
There are different ways to find the line equation.
Using the slope intercept form: y=mx+b
y=5x+b
Plug in the point's x&y values and solve for the y-intercept (0,b)
−2=5(5)+b
−2=25+b
−2−25=b
−27=b
Line equation: y=5x−27
Using the point slope form: y−y1=m(x−x1)
Plug in the point's xy values into x1,y1y−−2=5(x−5)
Simplify and distribute:
y+2=5x−25
y=5x−25−2
y=5x27
Answer:
Option B, y + 3 = -7/3(x - 2)
Step-by-step explanation:
<u>Point slope form: (y - y1) = m(x - x1)</u>
<u />
<u>Step 1: Find the slope</u>
m =
m =
m =
m =
<u>Step 2: Plug into the point slope form</u>
(y - 4) = -7/3(x - (-1))
(y - 4) = -7/3(x + 1)
OR
(y - (-3)) = -7/3(x - 2)
y + 3 = -7/3(x - 2)
Answer: Option B, y + 3 = -7/3(x - 2)
Answer: Lakesha gave away eighth tenths (8/10) of her cookies
Step-by-step explanation:
portion/Fraction of cookies given to Bailey =three tenths =3/10
portion/Fraction of cookies given to Helen =Five tenths =5/10
fraction of cookies given away by Lakesha= 3/10 +5/10=8/10 =eighth tenths
