For the given pair of equations, give the slopes of the lines, and then determine whether the two lines are parallel, perpendicular, or neither.
10x - 3y = 3
3x + 10y = 30
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The slope of 10x - 3y = 3 is
(Type an integer or a simplified fraction.)
O B. The slope of 10x - 3y = 3 is undefined.
Answers
Answer/Step-by-step explanation:
Given,
10x - 3y = 3
3x + 10y = 30
Rewrite both equation in slope-intercept form, y = mx + b.
Where, m = slope of the line.
Thus,
✔️10x - 3y = 3
-3y = -10x + 3
y = 10/3x - 1
Slope of this line would be 10/3
✔️3x + 10y = 30
10y = -3x + 30
y = -3/10x + 3
The slope of this line is -³/10.
✔️The two lines are pendivukar to each other because the slope of one is the negative reciprocal of the other.

Answer:
look at picture
Step-by-step explanation:
The graph that represents the inequality is given.
What is inequality?Inequality is a relationship where two expressions or values are not equal to each other.
For origin test, substitute x=0, y=0 into the first inequality.
0+0>4
Since the obtained inequality is not true, the origin will not be included in the shaded region.
For origin test, substitute x=0, y=0 into the second inequality.
2(0)-0>2
0>2
Since the obtained inequality is not true, the origin will not be included in the shaded region.
In both inequalities, since the equal to "=" sign is not included, the lines will be dotted.
Plot the dotted lines, x+y=4 and 2x-y=2 on the same graph and shade the region not including the origin.
Thus, the graph of the given system of inequalities is given in the image.

Directions: Find the Surface Area
Answers
Answer:
Surface area = 92 ft²
Step-by-step explanation:
Formula to find the surface area of a rectangular prism is,
Surface area = 2(lb + bh + hl)
Here, l = length of the prism
b = width of the prism
h = height of the prism
By substituting the measures of the sides given in the picture,
Surface area = 2(2×3 + 3×8 + 8×2)
= 2(6 + 24 + 16)
= 2(46)
= 92 square feet

Sofia is investing $8,000 in an account paying 5.5% interest compounded quarterly. What will Sofia's account balance be in 7 years?
Answers
Sofia's account balance in 7 years will be $11,726.12
Compound InterestFrom the question, we are to determine Sofia's account balance in 7 years
Using the compound interest formula,
[tex]A = P(1+ \frac{r}{n} )^{nt}[/tex]
Where A is the amount
P is the principal
r is the rate
n is the number of times compounded
and t is the time in years
From the given information,
P = $8,000
r = 5.5% = 0.055
n = 4
t = 7
Putting the parameters into the equation, we get
[tex]A = 8000(1+ \frac{0.055}{4} )^{4\times 7}[/tex]
[tex]A = 8000 ( 1+ 0.01375)^{28}[/tex]
[tex]A = 8000 ( 1.01375)^{28}[/tex]
A = $11,726.12
Hence, Sofia's account balance in 7 years will be $11,726.12

Answer:
m∠G = m∠H = 50
m∠I = 80
Step-by-step explanation:
m∠H = m∠G {Isosceles triangle property}
5x - 5 = 3x + 17 {Subtract 3x from both sides}
5x - 3x - 5 = 17 {Combine like terms}
2x - 5 = 17 {Add 5 to both sides}
2x = 17 + 5
2x = 22
x = 22/2
x = 11
m∠H = 5x - 5
= 5*11 - 5
= 55 - 5
m∠H = 50
m∠G = m∠H = 50
m∠G + m∠H + m∠I = 180 {Angle sum property}
50 + 50 + m∠I = 180
100 + m∠I = 180
m∠I = 180 - 100
m∠I = 80
Answer:
m∠G = m∠H = 50
m∠I = 80

If AD = 12 and AC = 4y-36, find the value of y
Answers
Answer:
y=12
Step-by-step explanation:
in that case, then 12 = 4y -36
12 =4y -36
12+36=4y
48=4y
48/4=y
12=y
answer :y=12
Answer:
y = 15
Step-by-step explanation:
Consider that the attached screenshot is the figure given in the problem. Also consider that DC = 12, due to the fact that AD = 12, and there is a midpoint at point D.
AD + DC = AC
12 + 12 = 4y - 36
24 = 4y - 36
+ 36 + 36
60 = 4y
60/4 = 4y/4
y = 15

Answer:
since all bundles contain the same amount of each type of rose, and one bundle has 9 climbing roses. two bundles will have 18 climbing roses. the question wants to know how many roses out of the two bundles won't be climbing roses. so you need to do: 300 - 18 = 282

What is the value of X
Answers
Answer:
the answer is 70.
Step-by-step explanation:
Since x and 80 are non-adjacent co-interior angles with respect to ( 2x +10 )
So,
x + 80 = 2x + 10 ( sum of two non-adjacent co-interior angles is equal to the exterior angle of that triangle )
=> 80 - 10 = 2x - x *( switching sides of x and 10 )
=> 70 = x
So, the value of x is 70
x + 80 = 2x + 10 (exterior angle property)
2x -x = 80 -10
x = 70
