write the slope-intercept form of the equation of each line. (DONT do number 26 )

Answer:

10 km

Step-by-step explanation:

volume of cube = s^3

1 m = 100 cm

volume = s^3 = (1 m)^3 = (100 cm)^3 = 1,000,000 cm^3

Since 1 m^3 = 1,000,000 cm^3, when you lay down the 1-cm cubes in a straight line with the edges touching, the line is 1,000,000 cm long.

1,000,000 cm = 10,000 m = 10 km

y = - 0.5x + 5.5 is the equation of a line perpendicular to line CD in slope-intercept form that passes through the point (−1, 6).

The slope-intercept form of a straight line is y = mx + c.

Here, x and y are coordinates, m is the slope and c is the y-intercept of the line.

Given, two points are C(1, 1) and (3, 5).

Therefore, equation of the line CD is:

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

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

⇒  [tex]\frac{x - 1}{y-1}[/tex] = [tex]\frac{-2}{-4}}[/tex]

⇒2(x - 1) = (y - 1)

⇒ y = 2x - 1

Let, line AB is perpendicular to the line CD and passes through the point (-1, 6).

Therefore, slope of the line CD is = 2.

We know, slope of CD × slope of AB = -1

Therefore, slope of AB = -1 / slope of CD = [tex]-\frac{1}{2}[/tex].

Now, line AB has a slope of [tex]-\frac{1}{2}[/tex] and passes through the point (-1, 6).

Therefore, equation of the line AB is:

(y - y₁) = m(x - x₁)

⇒ [y - (6)] = [tex]-\frac{1}{2}[/tex][x - (- 1)]

⇒ 2(y - 6) = (-x - 1)

⇒ 2y - 12 + x + 1 = 0

⇒ x + 2y = 11

⇒ y = - 0.5x + 5.5

Answer:

Step-by-step explanation:

A.

slope of f(x) remember that m=rise /run and see how you get from point (0,0) to (1,3) for example

m= rise 3/ run 1= 3

slope of g(x) you find by comparing it to y=mx+b wher m is slope and b is intercept so g(x) slope is m = 7

Slope of f(x) is 3 and slope of g(x) is 7 so g(x) go upward  faster.

B.

again compare g(x) =7x+2 with y=mx+b where b is the y-intercept

g(x) has y-intercept at (0,2)

we can see from the table that at x=0 the y-intecept is 0

f(x) has y-intercept at (0, 0)

g(x) has a greater y-intercept point

Answer:

The inequality which represents the graph is y ≤ -2x + 1 ⇒ A

Step-by-step explanation:

To solve the question you must know some facts about inequalities

Let us study the graph and find the correct answer

∵ The line represented the inequality is solid

∴ The sign of inequality is ≥ or ≤

→ That means the answer is A or B

∵ The shaded area is the area of the solutions of the inequality

∵ The shaded area is below the line

∴ The sign of inequality must be ≤

→ That means the correct answer is A

∴ The inequality which represents the graph is y ≤ -2x + 1

Answer:

y is fifty four

Answer:

x= 18 degrees and y=54 degrees

Step-by-step explanation:

Look at the top of the line AB. You can see that

3x+y+72=180

Now, look at the left side of the line CD. You can see that

y+90+2x=180

Hence, you have 2 equations in 2 unknows, which are possible to solve.

In resume, the 2 equations are:

3x+y+72=180

2x+y+90=180

By substracting the second equation to the first one, it yields

x-18=0

which implies x=18.

Now, we can susbstitute this value on the fist equation:

3(18)+y+72=180

54+y+72=180

y+126=180

y=180-126

y=54

We can corroborate these result in the second equation:

2(18)+54+90=

36+54+90=

90+90=

180.

Answer:  John is 18 now

Step-by-step explanation:

If his age 5 years ago was half of his age 8 years from now, the equation can show that doubling that age will be equal to his current age plus  8 years.

2(x-5) = x + 8 .  diistribute

2x - 10 = x + 8  Subtract x from both sides 2x -x +10 = x-x +8

x -10 = 8 . Add 10 to both sides . x -10 +10 = 8 + 10  simplify.

x = 18

Check:

18-5=13,  18+8= 26 .  13 is half of 26. True.

Putting the value of x in equation u will get the value of y

The required table of values given that y = 5x + 20 will be given as

x y

2 30

3 35

4 40

Given the linear equation y =5x + 20

In order to fill the table, we will have to calculate the y-values for the corresponding x values given.

If x = 2

y = 5(2) + 20

y = 10 + 20

y = 30

If x = 3

y = 5(3) + 20

y = 15 + 20

y = 35

If x = 4

y = 5(4) + 20

y = 20 + 20

y = 40

The first one is -40. The second one is -20.

Step-by-step explanation:

With the 1st one you do 17-12 which is 5 and 5*-8 is -40. With the 2nd one, 8-(-2) is 10 and 10*-2 is -20.

Answer:

Statement A is TRUE.

Given an x value of 15, y would be ;

= 2.72 * 15

= 40.8

Coordinates would therefore be (15, 40.8)

Statement B is FALSE.

The coordinates of Y given are impossible given the coordinates of X. In this scenario, Y must always be greater than X as a result of the equation.

Statement C is TRUE.

The slope in the equation takes the form of the $2.72 price being charged per gallon of gasoline such that the total price of x gallons can be calculated by multiplying the number of gallons by $2.72

Statement D is FALSE.

If the price of gasoline were to decrease by $0.03, the slope would become 2.69 not 2.75. 2.75 would be the new slope if the price had increased by $0.03 instead of decreased.

To prove these equation are the same

multiply every quantity by 2 using the multiplication property of equality.

[ -6x + 8y = 12 ] = 2 [ -3x + 4y = 6 ]

2(-3x) + 2(4y) = 2(6) = 2(-3x) + 2(-4y) - 2(6) = -6x + 8y = 12 = -6x + 8y - 12

2(-3x) + 2(4y) - 2(6) = -6x + 8y - 12

-6x + 8y - 12 = -6x + 8y - 12

The equation in slope-intercept form for the given line is 3y = -4x -3

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that a line passes through the point (-6,7) and has a slope of -4/3.

Standard equation of a line = y = mx + c where m is the slope,

Therefore, putting values of x and y to get the value of c

7 = -6*-4/3 + c

c = 7 - 8

c = -1

Equation = y = -4x/3 -1

Or, 3y = -4x -1

Hence, the equation of a line passing through the point (-6,7) and has a slope of -4/3 is 3y = -4x -1

Answer:

hypotenuse leg theorem or OHL

Step-by-step explanation:

Since the congruent angle is a right angle and it is not included, the two congruent sides of the triangles must include their hypotenuses and one of their legs.

The triangles would be congruent by the hypotenuse leg theorem, which states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, the triangles are congruent.

The congruence theorem that can be used to prove both triangles are congruent is: AAS

As per this theorem the two triangles are congruent if two angles and a side not between these two angles of one triangle are congruent to two corresponding angles and the corresponding side not between the angles of the other triangle.

This one denotes Angle - Angle - Side and it means that if 2 angles and the non-included side of a triangle are equal to corresponding 2 angles and the non-included side of another triangle, then they are both congruent.

When we have two triangles in which the two angles and a non-included side of one is congruent to the corresponding two angles and corresponding non-included side of the other, both triangles can be proven to be congruent by the AAS Congruence Theorem.

Since the two sides and the non-included side of one triangle is congruent to the corresponding two sides and the non-included side of the other, the congruence theorem that can be used to prove both triangles are congruent is: AAS
