Name the slope and y-intercept of the graph of 3x - 2y = 18 A. B. 2 3 -6 6 C. -3.-9 D. 2 -9
Answers
Answer:
D. 3/2, -9
Step-by-step explanation:
First, rearrange the equation 3x - 2y = 18 into the slope-intercept form of y = mx + b:
3x - 2y = 18
2y = 3x - 18
y = 3x/2 - 9
from this, u can tell that the slope is 3/2 and the y-intercept is -9 (option D)
hope this helps!

y=5x-7
-3x-2y=-12
Find x
Answers
Answer:
11/6=x
Step-by-step explanation:
System of Linear Equations entered :
[1] y=5x-7
[2] -3x-3y=-12
Equations Simplified or Rearranged :
[1] y - 5x = -7
[2] -3y - 3x = -12
Graphic Representation of the Equations :
-5x + y = -7 -3x - 3y = -12
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 7
// Plug this in for variable y in equation [2]
[2] -3•(5x-7) - 3x = -12
[2] - 18x = -33
// Solve equation [2] for the variable x
[2] 18x = 33
[2] x = 11/6
// By now we know this much :
y = 5x-7
x = 11/6
// Use the x value to solve for y
y = 5(11/6)-7 = 13/6
Solution :
{y,x} = {13/6,11/6}

There are 9 apples and 24 plums in a fruit bowl. What is the ratio of plums to apples?
Answers
Answer:
24:9 or 24 to 9 or [tex]\frac{24}{9}[/tex]
Step-by-step explanation:
The amount of plums is 24. The amount of apples is 9. So to write the ratio of plums (24) to apples (9), you write 24 to 9. You can either write a colon - 24:9 - a to - 24 to 9 - or as a fraction - [tex]\frac{24}{9}[/tex]. But, you have to write it with plums first.

A circle is drawn inside a square so its circumference touches each of the four sides of the
square. If the area of the circle is 125.8cm2 calculate the length of the sides of the square.
Answers
Answer:
12.66 cm
Step-by-step explanation:
Area of the circle = 125.8 Sq cm
[tex] \therefore \: \pi {r}^{2} = 125.8 \\ \\ \therefore \: 3.14 \times {r}^{2} = 125.8 \\ \\ {r}^{2} = \frac{125.8}{3.14} \\ \\ {r}^{2} = 40.0636943 \\ \\ {r} = \sqrt{40.0636943} \\ \\ r = 6.32958879 \\ \\ r \approx \: 6.33 \: cm \\ \\ d \: = 2r \\ \\ d = 2 \times 6.33 \\ \\ d = 12.66 \: cm \\ [/tex]
Diameter of the circle = 12.66 cm
Since, circumference of the circle touches each of the four sides of the square.
So, length of the sides of the square
= diameter of the circle.
= 12.66 cm

Step-by-step explanation:
Alright. Let's start by finding the length of this shaded area. The full length of the rectangle is 'm', and the part that is not shaded has a length of '2', so if we subtract the full length and the non-shaded length, we will get the shaded part's length. This is 'm-2'. The width/height we already know...it is 6, so-

I NEED HELP!!! You deposit $1,500 in an account earning 2.75% simple interest. How long will it take for the balance of the account to be $1,995?
Answers
12 months if interest is paid monthly
Step-by-step explanation:
2.75% of $1500 is $41.25 interest per period
$1995-$1500 = $495 total interest
$495 ÷ $41.25 = 12 periods
Therefore it takes 12 interest periods to reach $1995, so the answer is 12 months or 12 years depending on how often interest is paid.

The answer is <ACD = 68°
Step-by-step explanation:
Using the property that the sum of interior angles in a triangle is equal 180°,we have:
<DAC + <ACD + <ADC = 180°
[tex]2x + (180 - 4x) + 56 = 180 \\ - 2x + 56 = 0 \\ 2x = 56 \\ x = \frac{56}{2 } \\ x = 28[/tex]
Finally, calculating the angle <ACD, we have:
<ACD = 180 - 4x
<ACD = 180 - 4 . 28
<ACD = 180 - 112
ACD = 68°
Answer:
x = 28°
m∠ACD = 68°
Step-by-step explanation:
From inspection of the given diagram:
m∠FDC = 124°m∠EAB = 2xm∠ACG = 4xVertical Angle Theorem
When two straight lines intersect, the vertical angles are congruent.
⇒ m∠DAC = m∠EAB = 2x
Angles on a straight line sum to 180°:
⇒ m∠ACD + 4x = 180°
⇒ m∠ACD + 4x - 4x = 180° - 4x
⇒ m∠ACD = 180° - 4x
Exterior Angle Theorem
The exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle.
⇒ m∠DAC + m∠ACD = m∠FDC
⇒ 2x + (180° - 4x) = 124°
⇒ -2x + 180° = 124°
⇒ -2x + 180° - 180° = 124° - 180°
⇒ -2x = -56°
⇒ -2x ÷ -2 = -56° ÷ -2
⇒ x = 28°
To find m∠ACD, substitute the found value of x into the expression for the angle:
⇒ m∠ACD = 180° - 4x
⇒ m∠ACD = 180° - 4(28°)
⇒ m∠ACD = 180° - 112°
⇒ m∠ACD = 68°
