Answer:
X going up by 4s Y going up by 16s
Step-by-step explanation:
X
-7+4=-3
-3+4=1
1+4=5
And so on...
Y
-28+16=-12
-12+16=4
4+16=20
And so on...
If this is meant for slope then you would use the formula m=y2-y1/x2-x1
You can use -12 to equal y2 and -21 to equal y1
You can use -3 to equal x2 and -7 to equal x1
Now your equation should be...
m=-12-(-21)/-3-(-7)
m=9/4
9 is the rise
4 is the run
the slope is 9/4
Y-intercept for would be...
m=9/4x
Hope this helps :)

Dante drove 405 miles using 20 gallons of gas.At this rate,how many gallons of gas would he need to drive 243 miles
[tex]\begin{array}{ccll} miles&gallons\\ \cline{1-2} 405&20\\ 243&g \end{array}\implies \cfrac{405}{243}=\cfrac{20}{g}\implies \cfrac{5}{3}=\cfrac{20}{g}\implies 5g=60 \\\\\\ g = \cfrac{60}{5}\implies g = 12[/tex]

find the area of the quadrilateral.
Step-by-step explanation:
the area of a triangle is baseline × height / 2.
we have 2 major triangles that define this quadrilateral :
A-D-B and C-D-B.
both triangles have the same baseline : M_D + M_B = 14 cm
what we need to do is get the 2 heights M_C and N_A.
N_A we know already : 8 cm
so,
area A-D-B = 14×8/2 = 14×4 = 56 cm²
M_C we get via Pythagoras of the right-angled triangle D-M-C :
D_C² = M_C² + M_D²
10² = M_C² + 6²
100 = M_C² + 36
64 = M_C²
M_C = 8 cm
so,
area C-D-B = 14×8/2 = 56 cm²
so, the total area of the quadrilateral is
56 + 56 = 112 cm²

the hypotenuse of 68 and 51
Answer:
Hypotenuse is 85
Step-by-step explanation:
Use the Pythagorean theorem to solve:
a^2+b^2=c^2
Answer:
85
Step-by-step explanation:
Pythagorean Theorem
a^2 + b^2 = c^2
Therefore
68^2 = 4624
51^2 = 2601
4624+2601 = 7225
square root of 7225 = 85
To find the area of a triangle, you can use the expression b × h ÷ 2, where b is the base of the triangle and h is its height. What is the area of a triangle with a base of 4 and a height of 6?

The length of a rectangle is 5 cm longer than its width.
If the perimeter of the rectangle is 34 cm , find its area.
Answer:
A=66
Step-by-step explanation:
P=2(L+W) A= 11x6=66
34=2(x+5+x)
34=2(2x+5)
34/2 = 17
17=(2x+5)
17-5=12
12 divided by 2=6
so witch = 6 so 6+5=11 L= 11
I need Help ASAP I will give you brainlest and plus 5 stars ✨✨and plus thanks and 50 points EVeryONe need help this is due today so plz help me I need to turn it in today so plz help I will give everything if you do
Answer:
IT IS THE LAST ONE
I did this a long time ago
someone help me please i don’t know how to do square units
Answer: 78.
Explaination:
To calculate the area of a triangle, multiply the height by the width aka the "base" then divide by 2.
In this case, the height is 13 and the width is 12.
[tex]S = \frac{height.width}{2} = \frac{13.12}{2} = 78[/tex].

An analysis of past maintenance costs indicates that maintenance cost is an average of $0.20 per machine-hour at an activity level of 10,000 machine-hours and $0.25 per machine-hour at an activity level of 8,000 machine-hours. If this activity is within the relevant range, what is the total expected maintenance cost if the activity level is 8,700 machine-hours?
Answer: $2000
Step-by-step explanation:
Variable cost = Change in cost ÷ Activity change
($2000 - $2000) ÷ (10000 - 8000) = $0
Fixed cost element = Final cost - Variable cost
$2000 - ($0.00 ×10000) = $2000
Therefore, the cost formula for total maintenance is $2000 plus $0 per hour
y = $2,000 + $0x
At a level of 8,700 machine-hours, the total cost is:
y = $2000 + ($0.00 ×8700) = $2000
Sin(x-y)+sin(x-y prove the identity
Step-by-step explanation:
[tex] \sin(x - y) + \sin(x + y) = 2 \sin(x) \cos(y) [/tex]
We use the sum and difference identities.
Remeber the sum difference identity is
[tex] \sin(x + y) = \sin(x) \cos(y) + \cos( x ) \sin(y) [/tex]
and
[tex] \sin(x - y) = \sin(x) \cos(y) - \sin(x) \cos(y) [/tex]
So we get
[tex] (\sin(x) \cos(y) - \sin(y) \cos(x) ) + \sin(x) \cos(y) + \sin(y) \cos(x) [/tex]
Combine like Terms.
[tex]2 \sin(x) \cos(y) = 2 \sin(x) \cos(y) [/tex]

The sum of a number and 12 3/4 is 16 4/9. Find the number.
Answer:
3 25/36
Step-by-step explanation:
16 4/9 - 12 3/4 = 3 25/36
Answer:
[tex]x + 12 \frac{3}{4} = 16 \frac{4}{9} \\ \\ x + \frac{51}{4} = \frac{148}{9} \\ \\ x = \frac{148}{9} - \frac{51}{4} \\ \\ x = \frac{592}{36} - \frac{459}{36} \\ \\ x = \frac{133}{36} \\ \\ \\ x = 3 \frac{25}{36} [/tex]
So; the number
[tex]3 \frac{25}{36} [/tex]
