Answer:
X=2, y=8
Step-by-step explanation:
Y=-x+10 equation 1
y=2x+4 equation 2
-x+10=2x+4. Substitute y of first equation into 2nd equation
-x-2x+10=4
-3x=4-10
-3x=-6
x=2
solve for y by inserting x value into either equation
y=-x+10
y=-2+10
y=8
check answer
y=2x+4
8=2(2)+4
8=4+4
8=8

a. y = -3/2x+9
b. y = -2/3x+18
c. y = 2/3x+6
d. y = 3/2x+6
Answers
Answer:
A. y = -3/2x + 9
Step-by-step explanation:
In slope intercept form (y = mx + b), b represents the y-intercept. Therefore, simply look on the graph where the line intersects with the y-axis. In this case, that is all that was needed since we can clearly see that equation A is the only one with a y-intercept of 9.
Answer:
a
Step-by-step explanation:
any two points on the line are
(0,9 ) and (4,3)
slope=(3-9)/(4-0)=-6/4=-3/2
y intercept is 9
so eq. of line is y=-3/2x+9

Write the equation in standard form for the circle with center (-7,0) and radius 4 7
Answers
Answer:
x² + y² - 8x -14y - 105 = 0
Step-by-step explanation:
The centre of the circle is (-7,0) and the radius is (4,7) . Firstly let's find the radius using Distance formula .
=> D = √{ (-7-4)²+(0-7)²}
=> D = √ 11² + 7²
=> D = √ 121 +49
=> D = √170
Now using the standard equation of circle ⭕ ,
=> ( x - h)²+(y-k)² = r²
=> ( x - 4)²+(y-7)²= (√170)²
=> x² + 16 -8x + y² + 49 -14y = 170
=> x² + y² -8x -14y = 170 -65
=> x² + y² - 8x -14y - 105 = 0
• Hence the equation of circle is x² + y² - 8x -14y - 105 = 0 .Can someone HELP ME ON NUMBER 16 IM NOT SURE IM RIGHT!!!

Answers
Answer:
44.1
Step-by-step explanation:
Cosine = Adjacent over Hypotenuse
Adjacent of ∠T = 28 and hypotenuse = 39
Which means that [tex]cos(x)=\frac{28}{39}[/tex]
Now we solve for x
To get rid of the "cos" we take the inverse of cos ( which is [tex]cos^-^1[/tex] ) and apply it to each side
[tex]cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855[/tex]
We're left with x = 44.11461855
Our last step is to round to the nearest tenth and we get that the answer is 44.1

Perimeter of ΔABC = 16.46 units
Step-by-step explanation:
By applying cosine rule (CAH) in the given triangle ADB,
cos(∠BAC) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(55°) = [tex]\frac{3}{AB}[/tex]
AB = 5.23 units
Since, ΔABC is an isosceles triangle
AB = BC = 5.23 units
AD = DC = 3 units [Perpendicular drawn from a vertex of an isosceles triangle is a perpendicular bisector of the opposite side]
Therefore, AC = AD + DC = 6 units
Now perimeter of ΔABC = AB + BC + AC
= 5.23 + 5.23 + 6
= 16.46 units

QUESTION:
What is mBDG?
Answers
Answer:
242
Step-by-step explanation:
Circles have a total of 360°
mDBG does not include mBA or mGA
This means that mDBG = 360 - ( mBA + mGA )
mBA = 28° ( this is given )
mGA = 90° ( this is also given; it's indicated by the right angle )
Thus, mDBG = 360 - ( 28 + 90 )
28 + 90 = 118
mDBG = 360 - 118
360 - 118 = 242
Hence, mDBG = 242
On a ship the ratio of crew members to passengers is 1:15. There are 540 passengers. How many crew members are there?
Answers
Answer: 36
Step-by-step explanation: Keep multiplying 15 until you get 540. 36 * 15 is 540
Answer:
36 Crew members
Step-by-step explanation:
Divide 540 by 15, to find how much the new amount of passengers had increased. It should be 36.
Now to keep the ration even, you need to multiply the amount of Crew members by 36 too.
Double checking your answer:1/15=0.06666666667...
36/540=0.06666666667...
There's probably other ways to solve this, this is just how I did it.
