Answer:
A) 6x + 6y = 24, Yes, they have the same solution set
Step-by-step explanation:
Let's first start by multiplying the equation by 3:
(2*3)x + (2*3)y = 24
6x + 6y = 24
Now lets find the solution set for both:
6y = -6x + 24
y = -x +4
2y = -2x + 8
y = -x +4
Yes, they have the same solution set

Answer:
formulla of perimeter of rectangle
Step-by-step explanation:
perimeter of rectangle=2(l+b)
= 2(7.5+3.25)
=2(11.25)= 22.5
Step-by-step explanation:
l = 7.5cm
b = 3.75cm
perimeter of rectangle = 2(l+b)
= 2(7.5+3.75)
= 2(11.25)
=22.5cm

What is the equation of this line in slope intercept forn?
3z +y=2
A. y=-3+2
B. y=3z +2
C. y=-3z 2
D. y=3r-2
Answer:
We conclude that the equation of this line in the slope-intercept form will be:
[tex]y = -3z+2[/tex]Step-by-step explanation:
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
Given the equation
[tex]3z +y=2[/tex]
Writing the equation in the slope-intercept form of the line equation by simplifying it
subtracting 3z from both sides
[tex]3z+y-3z = -3z+2[/tex]
[tex]y = -3z+2[/tex]
Therefore, we conclude that the equation of this line in the slope-intercept form will be:
[tex]y = -3z+2[/tex]7

Marcus needs to bike at least 80 miles this week for his training.If he has already biked 25 miles this week ,then how many miles should he bike on each of the 5 remaining days this week?
Answer:
11
Step-by-step explanation:
So if he already biked 25 miles we can subtract 80 and 25 which will get a total of 55. if we divided 55 miles to the rest of the 5 days he will have to bike 11 miles each day

The equation in point-slope is [tex]\mathbf{y+5=3(x-6)}[/tex]
Step-by-step explanation:
We need to write the point-slope form of the equation of the line passing through the point (6,-5) and perpendicular to the line [tex]y=-\frac{1}{3}x+4[/tex]
The general form of point-slope is; [tex]y-y_1=m(x-x_1)[/tex]
where m is slope and [tex](x_1,y_1)[/tex] is the point
We need to calculate slope.
We are given equation of line [tex]y=-\frac{1}{3}x+4[/tex] that is perpendicular to the required line.
The equation is given in slope-intercept form [tex]y=mx+b[/tex] where m is slope.
Comparing both equations we get m= -1/3
But we know that when lines are perpendicular their slopes are opposite reciprocal of each other i.e [tex]m=-\frac{1}{m}[/tex]
So, slope of required line is m = 3 (opposite reciprocal of -1/3)
Now, the equation in point-slope form having slope m=3 and point (6,-5) is
[tex]y-y_1=m(x-x_1)\\y-(-5)=3(x-6)\\y+5=3(x-6)[/tex]
So, The equation in point-slope is [tex]\mathbf{y+5=3(x-6)}[/tex]

180=x+(3x-8)
Answer:
x=47
Step-by-step explanation:
Let's solve your equation step-by-step.
180=x+3x−8
Step 1: Simplify both sides of the equation.
180=x+3x−8
180=x+3x+−8
180=(x+3x)+(−8)(Combine Like Terms)
180=4x+−8
180=4x−8
Step 2: Flip the equation.
4x−8=180
Step 3: Add 8 to both sides.
4x−8+8=180+8
4x=188
Step 4: Divide both sides by 4.
4x4=1884
x=47

Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. When he starts his shift, the water level shows 8 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
150 minutes
160 minutes
170 minutes
180 minutes
Answer: b. 160
Step-by-step explanation: just took the test
There are 160 minutes would the water level be less than or equal to 64 cups.
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Here, The equation we're given is,
W = -0.414t + 129.549,
which an be written as,
-0.414t + 129.549 = W.
Now, We are asked to find the amount of time it would take for the water level to be less than or equal to 64 cups.
Plugging this information in, we have:
-0.414t + 129.549 ≤ 64
To solve this, we first cancel 129.549 by subtracting from both sides:
-0.414t + 129.549 - 129.549 ≤ 64 - 129.549
-0.414t ≤ -65.549
Now divide both sides by -0.414:
-0.414t/-0.414 ≤ -65.549/-0.414
t ≥ 158.33
(When we multiply or divide both sides of an inequality by a negative number, we must flip the inequality symbol.)
t ≥ 160 minutes
Thus, There are 160 minutes would the water level be less than or equal to 64 cups.

A 220-inch pipe is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece.
The shorter piece is
inches long
Answer:
let x be the length of the shorter piece.
4x + x= 210
x= 42.
4x= 168
The shorter piece is 42in and the long piece is 168 in.
The length of the shorter piece will be;
⇒ x = 44 inch
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
A 220-inch pipe is cut into two pieces.
And, One piece is four times the length of the other.
Now,
Since, One piece is four times the length of the other.
Let height of shorter piece = x
Then, The height of longer piece = 4x
Hence, We can formulate;
⇒ x + 4x = 220
Solve for x as;
⇒ 5x = 220
⇒ x = 220 / 5
⇒ x = 44
Thus, The length of the shorter piece will be;
⇒ x = 44 inch

Which answer choice do I pick?
Answer:
D. f(x) = 8x
Step-by-step explanation:
At each increasing x point, the y point increases by 8, this means that for each x increasing by 1, y increases by 8, which means y = 8x
Answer:
Fourth choice, f(x) = 8x
Step-by-step explanation:
y is going up or down and x is left or right, u riht the slope like y/x
so it's going up 8 units every 1 unit it goes to the right so it's 8/1 which is 8 so 8 is ur slope
