I need help with these two problems.

Dennis_Churaev [7]

Answer:

the equation is - $y=x$

Explanation:

Given -

$y=x+4$

We have to find a line passing through the point $(2,2)$ nd parallel to the given line.

Find the slope of the given line.

It is the coefficeint of $x$

m₁ = 1

The two lines are parallel. Hence

m₂=m₁=1 Where m₂is the slope of the second line.

You have slope and the points $(2,2)$

Find the Y intercept

$y=mx+c\\2=(1)(2)+C\\2=2+C\\C=2-2=0$

Y-Intercept $C=0$ and slope m₂=1

Fix the equation

$y=x$

A boat makes a 120-mile trip downstream in 3 hours but makes the return trip in 4 hours. What is the rate of the current?

Gnom [1K]

With the current 40 miles per hour
Against the current 30 miles per hour
bv means boat velocity with NO current
cv means current velocity
A) bv + cv = 40 mph
B) bv - cv = 30 mph
Adding both equations:
2bv = 70
boat velocity with NO CURRENT = 35 miles per hour

Using equationA
bv + cv = 40
35 + cv = 40

current velocity = 5 miles per hour

mark and heather starr are celebrating their 25th anniversary by having a reception at local reception hall. they have budget 45

Lera25 [3.4K]

Answer:

Step-by-step explanation:

The $50 cleanup fee is a "fixed cost."

The "$30 per-person fee is a "variable cost." That is, it varies with the number of people.

"within" means "less than or equal to"

Cost = $50 + $30x [where x = number of people]

Cost ≤ $4500 ["stay within their budget"]

$50 + $30x ≤ $4500 [substitute for cost]

$30x ≤ $4450 [subtract $50 from both sides retains sense of inequality]

x ≤ 148.3333 [divide by +$30 retains sense of inequality]

Mark and Heather may invite up to 148 guests.

[note: to be "≤," always truncate, never round up]

Check:

148 people for $30 each + $50 is $4440+$50 = $4490.

One more person makes it $4520 -- that is too much.

There we go, my bad
