The system of equation which have no solution are A, B and D.

Slope defines rate of change or we can also say it is rise over run.

According to the given question we have to determine given system of equations which have no solution.

We know when two lines are parallel to each other they have no solution cause they have no common intersection points and we also know parallel lines have same slope with different y intercept.

Let us write all the system of equations in slope intercept form which is

y = mx + b.

A.

y = -3x + 5.

y = -3x + 4.

This system of equation has no solution cause have have same slope and different y intercept hence parallel to each other.

B.

y = 4x - 1.

4y = 16x - 1

y = 4x - 1/4.

Same slope different y intercept so no solution.

C.

-2y = -5x + 3.

y = (5/2)x - 3/2.

-4y = -10x + 6.

y = (5/2)x - 3/2.

Same slope same y intercept so they are on top of another so infinite no. of solutions.

D.

3x + 7y = 42

7y = - 3x + 42.

y = (-3/7)x + 6.

14y = -6x + 50.

y = (-3/7)x + 25/7.

Same slope different y intercept so they are parallel to each other.

E.

y =2x + 5.

y = 5x².

Different slope and y intercept so they are not parallel.

Step-by-step explanation:

The statements in the two column proof can be explained as follows;

Statement                     [tex]{}[/tex]                Explanation

1. p║q                    [tex]{}[/tex]                        Given

∠1 ≅ ∠11

2. ∠1 ≅ ∠9                     [tex]{}[/tex]               Corresponding angles on parallel lines crossed by a common transversal are congruent

3. ∠9 ≅ ∠11                    [tex]{}[/tex]               Transitive property of equality

Given that ∠1 ≅ ∠11 and we have that ∠1 ≅ ∠9, then we can transit the terms between the two expressions to get, ∠9 ≅ ∠11 which is the same as ∠11 ≅ ∠9

4. a║b                    [tex]{}[/tex]                       Corresponding angles on parallel lines are congruent

Whereby we now have ∠9 which is formed by line a and the transversal line q, is congruent to ∠11 which is formed by line b and the common transversal line q, and both ∠9 and ∠11 occupy corresponding locations on lines a and b respectively which are crossed by the transversal, line q, then lines a and b are parallel to each other or a║b.

Answer: 13095238095/100000000000

Step-by-step explanation:  To write 0.13095238095 as a fraction you have to write 0.13095238095 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.13095238095 = 0.13095238095/1 = 1.3095238095/10 = 13.095238095/100 = 130.95238095/1000 = 1309.5238095/10000 = 13095.238095/100000 = 130952.38095/1000000 = 1309523.8095/10000000 = 13095238.095/100000000 = 130952380.95/1000000000 = 1309523809.5/10000000000 = 13095238095/100000000000

Given:

[tex]\sum_{k=1}^{6}\dfrac{1}{4}(2)^{k-1}[/tex]

To find:

The values of r and [tex]a_1[/tex].

Solution:

We have,

[tex]\sum_{k=1}^{6}\dfrac{1}{4}(2)^{k-1}[/tex]

Here,

[tex]a_k=\dfrac{1}{4}(2)^{k-1}[/tex]        ...(i)

We know that, kth term of a GP is

[tex]a_k=a_1(r)^{k-1}[/tex]        ...(ii)

From (i) and (ii), we get

[tex]a_1=\dfrac{1}{4}[/tex] and [tex]r=2[/tex]

Therefore, the correct option is C.

Answer:

1) Subtracting one from the other

2) x = 0.375 and y = 0.125

Step-by-step explanation:

Equation 1 :

[tex]\frac{2x+1}{2y}=7\\\\[/tex]

Equation 2:

[tex]\frac{6x-1}{2y}=5[/tex]

To solve these equations by the Elimination method we multiply equation 1 with 6 and multiply equation 2 with 2 so now,

[tex]\frac{2x+1}{2y} =7\\\\2x+1=14y\\\\Multiplying\ Equation\ 1\ with\ 6\\\\12x+6=84y[/tex]

Now for the second equation:

[tex]\frac{6x-1}{2y}=5\\\\6x-1=10y\\\\Multiplying\ equation\ 2\ with\ 2 \\\\12x-2=20y[/tex]

Now subtracting equation 2 from equation 1

[tex]12x+6=84y\\\\12x-2=20y\\\\Subtracting\ leads\ to\\12x-12x+6-(-2)=84y-20y\\0+8=64y\\8=64y\\8/64=y\\0.125=y[/tex]

now insert this value of y into any equation

lets insert it into equation 1

[tex]\frac{2x+1}{2y} =7\\\\2x+1=14y\\2x+1=14(0.125)\\2x+1=1.75\\2x=1.75-1\\2x=0.75\\x=0.75/2\\x-0.375[/tex]

Answer:

heres the graph

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

for L to be parallel to M the two angles have to be supplementary so to add up to 180°

6x+8+4x+2 =180

10x+10 =180

10x = 180-10

10x = 170

x=170/10

x=17

Answer:

The numerator is the number on top of the bottom number (denominator)

Answer:

69

Step-by-step explanation:

X is 13 cause of the corresponding angles when you solve and then 3 is supplemebntary so 180-111 is 69

Step-by-step explanation:

180 - 111 = 69

Answer:

The new function is g(x) = -x + 4

Step-by-step explanation:

∵ A function f(x) = x

∵ It is vertically translated 4 units up

→ By using the 1st rule above, the value of k = 4

∴ k = 4

∵ Its image h(x) = f(x) + k

∴ Its image h(x) = f(x) + 4

∴ Its image h(x) = x + 4

∵ Then it is reflected across the y-axis

→ By using the 2nd rule above, change the sign of x in h(x)

∵ h(x) = x + 4

∴ g(x) = h(-x)

∴ g(x) = -x + 4

∴ The new function is g(x) = -x + 4

Answer:

y = [tex]\frac{5}{3}x-1[/tex]

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph attached,

Since, the given line passes through (0, -1) and (3, 4),

Slope 'm' = [tex]\frac{4+1}{3-0}[/tex]

m = [tex]\frac{5}{3}[/tex]

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = [tex]\frac{5}{3}x-1[/tex]

Answer:

812.5 inches

Step-by-step explanation:

Turn these numbers into fractions:

[tex]\frac{h}{900} \frac{65}{72}[/tex]

Solve 900/72 to get 12.5. This means that multiplying 72 x 12.5, you get 900. So, to find the height of the tree: h you multiply 65 x 12.5. Your answer to this is 812.5.
