Answer:

its the 2nd one

Step-by-step explanation:

y=mx+b

M=slope

B=y-intercept

Answer:

Slope: 5x    Y-Intercept: -7

Step-by-step explanation:

The slope is the rate at which it increases, the y-intercept is the point in the graph that crosses the y-axis

y=mx+b  

mx = slope

b = y-intercept

Answer:

The rule for the linear function will be:

f(x) = 5/2x - 4

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points

Finding the slope between (0, -4) and (2, 1)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]  

                 =  [1 - (-4)] / [2 - 0]  

                 = 5 / 2

Thus, the slope of the line = m = 5/2

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = -4

Thus, the y-intercept b = -4

Now, substituting m = 5/2 and b = -4 in the slope-intercept form of linear function

y = mx+b

y = (5/2)x + (-4)        ∵ m = 5/2, b = -4

y = 5/2x - 4

or

f(x) = 5/2x - 4     ∵  y = f(x)

Therefore, the rule for the linear function will be:

f(x) = 5/2x - 4

Graph [2] represents the correct relationship between Weeks and Money saved by Samantha.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is Samantha who created part of a table to show her savings. She saved at the same rate each week.

We have, Samantha’s Savings as -

Week                      1               2                  3                4

Money Saved       A               B                $18            $24

Since she saves at the same rate every week, therefore, the slope of the line will be -

m = (24 - 18)/(4 - 3)

m = 6/1

m = 6

Then -

A = 6

B = 12

The graph [2] represents the correct graph.

Therefore, graph [2] represents the correct relationship between Weeks and Money saved by Samantha.

Answer:

100% true....

subtracting 19 from both sides brings you to 2x=8, so x=4

Step-by-step explanation:

Hey there!

2x + 19 = 27

SUBTRACT by 19 to BOTH SIDES

2x + 19 – 19 = 27 – 19

Cancel out: 19 – 19 because that gives you 0

KEEP: 27 – 19 because that gives you the value of 8

New EQUATION: 2x = 8

DIVIDE by 2 to BOTH SIDES

2x/2 = 8/2

CANCEL out: 2/2 because that gives you 1

KEEP: 8/2 because that gives you the value of x

“8/2 = x”

Answer: x = 4 ☑️

Good luck on your assignment and enjoy your day!

Answer:

Alonzo scored 25 points. Miguel scored 29 points.

Step-by-step explanation:

25 plus 25 is 50. Plus 4 is 54.

Answer:

x=-1

Step-by-step explanation:

10+3x=5-2x     (Add 2x to both sides)

10+5x=5          (Subtract 10 from both sides)

5x=-5               (Divide both side by 5)

x=-1

Answer:

x=-1

Step-by-step explanation:

10 + 3x= 5 – 2x

You first +2x on both sides

10 + 3x+2x= 5 – 2x+2x

subtract 10 on both sides

10-10+5x=5-10

Then divide 5 to isolate x

5 divide 5x=-5 divide 5

x=-1

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 1) ← 2 points on the line

m = [tex]\frac{1-0}{0-(-2)}[/tex] = [tex]\frac{1}{0+2}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

51

Step-by-step explanation:

Given

m = 6 and n = 5

Now

m² + 3n

= ( 6) ² + 3 * 5

= 36 + 15

= 51

Answer:

[tex]consider \: triangle \: BDE \\m<BCD = m<BED \\ angles \: of \: triangle \: sum \: up \: to \: 180 ° \\ (14x + 4)° + 55° + 51° = 180° \\ 14x = 180° - (4 + 55 + 51)° \\ 14x = 70° \\ x = \frac{70}{14} \\ x = 5[/tex]

Answer:

x = 5

Step-by-step explanation:

all angles at corners in parallelogram must add to 360

bcd = 51 thus angle at opposite corner (bed) must also equal 51

adding = 51 + 51 = 102

angles at ebc and edc are also equal to each other

edf = 55 and cbf = 55

adding 55+55 = 110

360 - 110 - 102 = 148

divide by 2 for angles ebf and cfd

148/2 = 74

now solve

14x + 4 = 74

14x = 70

x = 5

Given :

Jaylen earns the same amount of money each month.

His telephone bill is 1/20 of his monthly earnings, and he pays a total of $840 each year for his telephone service.

To Find :

How much does Jaylen earn each month, in dollars.

Solution :

Monthly payment of telephone bill is :

[tex]M = \$ \dfrac{840}{12}\\\\M = \$70[/tex]

Let, his monthly salary is A.

So,

[tex]M = \dfrac{A}{20}\\\\A = 20\times M\\\\A = 20 \times 70\\\\A = \$1400[/tex]

Therefore, Jaylen monthly income is $1400.

Answer:

1) The conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].

2) -111

3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.

Step-by-step explanation:

1) A radical number of the form [tex]r = a + b\sqrt{c}[/tex], [tex]\forall \,a,b,c\in \mathbb{R}[/tex], where the first component is a non-radical real number which acts as a "pivot" and the second component is the radical component, which generates a "displacement" from pivot.

The conjugate of [tex]r[/tex] is a real number [tex]s = a - b\sqrt{c}[/tex],  [tex]\forall \,a,b,c\in \mathbb{R}[/tex], which that is "pivot" plus "displacement" in the direction opposite to that of [tex]r[/tex]. We proceed to complement this explanation with the image attached below.

Then, the conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].

2) We proceed to performed all the need algebraic operation until result is found:

4) [tex]6\cdot 6 +[6\cdot (-7)]\cdot \sqrt{3}+(6\cdot 7)\cdot \sqrt{3}+[7\cdot (-7)]\cdot (\sqrt{3}\cdot \sqrt{3})[/tex] Distributive, associative and commutative properties

5) [tex]36 +(-42)\cdot \sqrt{3}+42\cdot \sqrt{3}+(-49)\cdot 3[/tex] Definition of multiplication/[tex]-a\cdot b = (-a)\cdot b[/tex]/Definition of square root

6) [tex][36 +(-147)]+\sqrt{3}\cdot [42+(-42)][/tex] Commutative, associative and distributive properties/[tex]-a\cdot b = (-a)\cdot b[/tex]

7) [tex]-111+\sqrt{3}\cdot 0[/tex] Definition of subtraction/Existence of additive inverse

8) [tex]-111+0[/tex] [tex]a\cdot 0 = 0[/tex]

9) [tex]-111[/tex] Modulative property/Result

3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.

Answer:

slope = - 3

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line

m = [tex]\frac{-1-2}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3
