Answer:
undefined
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1- x2} }[/tex]
☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate.
Slope of the line
[tex] = \frac{ - 2 - ( - 10)}{ - 1 - ( - 1)} [/tex]
[tex] = \frac{8}{0} [/tex]
(undefined)
Notice that the 2 points have the same x-coordinate of -1, which means that the line is a vertical line. Vertical lines have an undefined slope.
last year Patrick paid £2534 for his annual train ticket this year he has to pay £2612 for his annual train ticket. work out the percentage increase in the cost of his train ticket. give your answer correct to 3 significant figures.
Answer:
Percentage increase in the cost of his train ticket = 3% (Approx.)
Step-by-step explanation:
Given:
Cost of annual ticket paid by Patrick last year = £2,534
Cost of annual ticket paid by Patrick current year = £2,612
Find:
Percentage increase in the cost of his train ticket
Computation:
Percentage increase = [(Current - Base) / Base]100
Percentage increase in the cost of his train ticket = [(2,612 - 2,534) / 2,534]100
Percentage increase in the cost of his train ticket = [(78) / 2,534]100
Percentage increase in the cost of his train ticket = [0.03078]100
Percentage increase in the cost of his train ticket = 3.078
Percentage increase in the cost of his train ticket = 3% (Approx.)

Solve the system of linear equations by substitution 12x+y=−4 y=2x+16
Answer:
Your solution is (-10/7, 92/7)
Step-by-step explanation:
12x + y = -4
y = 2x + 16
To use substitution, we want to plug one variable's equation into the other equation.
We can see that y is already solved for us. Plug y into the first equation.
12x + y = -4
12x + (2x + 16) = -4
Combine like terms.
14x + 16 = -4
Subtract 16 from both sides.
14x = -20
Divide both sides by 14.
x = -20/14
x = -10/7
Now that we know x, we will plug it into one of the other equations.
y = 2x + 16
y = 2(-10/7) + 16
Multiply.
y = -20/7 + 16
Add.
y = -20/7 + 112/7
y = 92/7
Your solution is (-10/7, 92/7)
Hope this helps!

Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form.
(3,7), and (7.3)
y=0
Answer:
y=10-x
Step-by-step explanation:
1. Find the slope of the equation using the formula (change in y/change in x)
(3-7)/(7-3)=-4/4=-1
2. Plug in the slope and one of the coordinate points to the slope-intercept form to find the y-intercept.
slope-intercept form: y=mx+b
7=-3+b
b=10
3. Put the slope-intercept form of the equation together.
y=10-x

Natalie is having a birthday party and it's time to cut
the cake.
Unfortunately she doesn't know how far she needs to
cut from the center to the edge of the cake.
She remembered the baker told her that the
circumference is 46 inches.
How far should Natalie cut?
**NO spaces
**Include units
**Round to the nearest hundredths
Answer:
7.32 inches
Step-by-step explanation:
The circumference of the circle is 46 inches, and you just have to find the radius... you do the 2xpixr=C backwards. So 2xpixr=46 simplify the expression; 6.28xr=46 then divide... r=46/6.28... Which rounds to 7.32 inches as the radius.
(And yes you are finding the radius if you are finding a line from the middle of the circle to an edge)
I hope this helps :))

(A) delta h(t) = 32
Step-by-step explanation:
Average rate of change delta h(t) is given by
[tex]delta \: h(t) = \frac{h(b) - h(a)}{b - a} [/tex]
at t = 0, h(0) = 80
at t = 2, h(2) = -16(4) + 64(2) + 80 = 144
Plugging in the numbers
delta h(t) = (144 - 80)/(2 - 0)
= 32

Step-by-step explanation:
write the slop intercept form of the equations below.
1. slope= 1/4,y intercept = 4
2. y-5=-4(x+1)
Step-by-step explanation:
Given :-
1. slope= 1/4,y intercept = 42. y-5=-4(x+1)And we need to find the slope intercept form of the line . The slope intercept form of a line is y = mx + c , where m is the slope and c is the y intercept. Substitute respective values ,
Solution 1 :-
[tex]:\implies[/tex] y = mx + c
[tex]:\implies[/tex] y = 1/4 x + 4
[tex]:\implies[/tex] 4y = x + 16
[tex]:\implies[/tex] x - 4y + 16 = 0
Solution 2 :-
[tex]:\implies[/tex] y - 5 = -4( x +1)
[tex]:\implies[/tex] y -5 = -4x -4
[tex]:\implies[/tex] y = -4x +1

A man bought a scooter for $100 and sold it for $120. He later bought it back for $140 and sold it again for $160. How much did he make or lose as a scooter salesman? (NO LINKS WILL REPORT WITH OUT HESITATION)
Answer:
Step-by-step explanation:
- 100
+ 120 = 20
-140 = -20
+160 = 20
so every time he sold it, he gained 20 and lost 20 every time he bought it back

A company manufactures aluminum mailboxes in the shape of a box with a half-cylinder top. The company will make 1863 mailboxes this week. If each mailbox has dimensions as shown in the figure below, how many square meters of aluminum will be needed to make these mailboxes? In your calculations, use the value for , and round up your answer to the next square meter.
9514 1404 393
Answer:
3433 m^2
Step-by-step explanation:
The total surface area is the sum of the end areas and the lateral area.
The end areas together are a circle of diameter 0.4 m and two rectangles that are 0.4 m by 0.55 m.
End areas = πr^2 + 2LW = 3.14(0.2 m)^2 + 2(0.4 m)(0.55 m)
= 0.1256 m^2 +0.44 m^2 = 0.5656 m^2
The perimeter of the end piece is half the circumference of a 0.4 m circle and three sides of a 0.4 m by 0.55 m rectangle.
P = (1/2)πd + 2L +W = 1/2·3.14·0.4 m + 2(0.55 m) + 0.4 m = 2.128 m
The lateral area of the mailbox is the product of its length and the perimeter of the end piece:
LA = PL = (2.128 m)(0.6 m) = 1.2768 m^2
Then the total surface area of the mailbox is ...
0.5656 m^2 + 1.2768 m^2 = 1.8424 m^2
__
The area of aluminum required for 1863 mailboxes is ...
1863 × 1.8424 m^2 ≈ 3433 m^2
About 3433 square meters of aluminum are needed to make these mailboxes.

YS = 2/3 × ( YV ) *.&.* SV = 1/3 × ( YV )
_____________________________
YS = 2/3 × ( YV )
4x + 14 = 2/3 × ( YV )
Multiply both sides by 3/2
( 4x + 14 ) × 3/2 = ( YV ) × 2/3 × 3/2
YV = 6x + 21 ( ☆ )
¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥
SV = 1/3 × ( YV )
1 + 3x = 1/3 × ( YV )
Multiply both sides by 3
( 1 + 3x ) × 3 = ( YV ) × 1/3 × 3
YV = 9x + 3 ( ♡ )
_____________________________
YV = YV
( ☆ ) = ( ♡ )
6x + 21 = 9x + 3
Subtract both sides 3
6x + 21 - 3 = 9x + 3 - 3
6x + 18 = 9x
Subtract both sides 6x
6x - 6x + 18 = 9x - 6x
18 = 3x
Divide both sides by 3
18 ÷ 3 = 3x ÷ 3
x = 6
₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩
YV = 6x + 21 = 9x + 3
YV = 6(6) + 21 = 9(6) + 3
YV = 57
