Answer: 1) y = (-5/7)x + 11/7
2) y = (-1/4)x - 3
3) y = (1/2)x - 1
Step-by-step explanation:
Use the Point-Slope equation: y - y₁ = m(x - x₁) where
(x₁, y₁) is a point on the linem is the slope(x₁, y₁) = (-2, 3) m = -5/7
y - 3 = -5/7(x + 2)
y - 3 = (-5/7)x - 10/7
y = (-5/7)x + 11/7
(x₁, y₁) = (-4, -2) m = -1/4
y + 2 = -1/4(x + 4)
y + 2 = (-1/4)x - 1
y = (-1/4)x - 3
(x₁, y₁) = (2, 0) m = 1/2
y - 0 = 1/2(x - 2)
y - 0 = (1/2)x - 1
y = (1/2)x - 1

find the unit rate.
2 1/2 miles in 3/4 hour
Answer: 3.33 miles per hour
Step-by-step explanation:
This is a fraction equal to
2.5 miles ÷ 0.75 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 0.75
[tex]\frac{2.5 miles}{0.75 hours}[/tex] ÷ 0.75
÷ 0.75
= 3.33 miles per hour

Find the value(s) of k so that the
parabola has only one x-intercept.
y = x2 + kx + 100
Answer:
PLEASE SOMEONE ANSWER THIS
Step-by-step explanation:
The parabola has only one x - intercept when k =20.
What is x-intercept?The x intercept for any curve is the value of the x coordinate of the point where the graph cuts the x-axis.
When the parabola has only one intercept?If the value of the discriminant is zero, there is one real solution for x. Then the parabola has only one x-intercept.
According to the given question
We have a equation of parabola
[tex]y = x^{2} + kx + 100[/tex]
The above parabola has only one x-intercept if the discriminant is zero.
⇒ [tex]k^{2} -4(1)(100) =0[/tex]
⇒ [tex]k^{2} = 400[/tex]
⇒[tex]k =\sqrt{400}[/tex]
⇒ k = 20
⇒ k = 20
Hence, the parabola has only one x - intercept when k =20.

2/9 divided by 7/9
could you help me with this please i really need help please.
Answer: 2/9 divided by 7/9 = 2/7
Step-by-step explanation:
1. Write out the problem on a piece of paper.
2. Change the second fraction, which is 7/9, into a reciprocal fraction (means flipping the 7 and 9 around). Now, our equation has the fraction 9/7 in it.
3. Change the division symbol to a multiplication symbol. Your equation should be 2/9 x 9/7.
4. Solve the equation. You should get the answer of 18/63 without simplification.
5. Simplify. 18/63 = 2/7
Conclusion: 2/7 is the correct answer.
Your favorite local band is selling merchandise and they have asked you to write an algebraic expression to represent their total profit. The are selling t-shirts for $15 each and CDs for $5 each.
Write an expression to represent the total profit for t number of shirts sold and c number of CDs sold.
Evaluate your expression for 10 shirts and 25 CDs sold.
Answer:
15t + 5c = b$275Step-by-step explanation:
Let "t' be the number of t-shirts bought.
Let "c" be the number of CDs bought.
Let b" be the total cost.
15t + 5c = b
We buy 10 t-shirts so t = 10.
We buy 25 CDs so c = 25.
We are trying to find b.
15t + 5c = b
15(10) + 5(25) = b
150 + 125 = b
275 = b
Best of Luck!
Answer:
15t + 5c = tptp = $275Step-by-step explanation:
t-shirts for $15 = t
cd's for $5 = c
let tp = total profit
the algebraic expression would be:
15t + 5c = tp
-------------------------
evaluate the expression 15t + 5c = tp
for t = 10 and c = 25
plugin values into the formula:
15(10) + 5(25) = tp
tp = 150 + 125
tp = 275
therefore, the total profit is $275

The mean age of 3 women in an office is 27 years old.
The mean age of 6 men in an office is 34 years old.
What is the mean age (nearest year) of all the people in the office?
Answer:
mean age of women
(x+y+z)/3=27
mean age of men
(x1+x2+x3+x4+x5+x6)/6=34
mean age of all people in the office
x+y+z=27*3=81
x1+...x6=34*6=204
so
mean age( x+y+z+x1+x2+..x6)/(3+6)=(27*3+34*6)/9
=(81+204)/9=285/9=32 approximately
