Solve the following equation for x give your answer in simplified form 1/4x +3y =8

Answers

x= 2 - 3/4y. if you do the equation, you would start by subtracting 3y from both sides. now you would have 1/4x= 8-3y. then you would divide both sides by 4, to get x= 2-3/4y.

hope this helps:)

The scale factor from triangles ABC to XYZ IS 6.

Option A is the correct answer.

What is a scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object,

We have,

ΔABC and ΔXYZ

The corresponding sides are:

AB = XY

BC = YZ

AC = XZ

Now,

We see that,

XY = 6 x AB

YZ = 6 x BC

XZ = 6 x AC

So,

The scale factor is 6.

Thus,

The scale factor from triangles ABC to XYZ IS 6.

A poster of the detroit lions football players uses a scale of 4 inches= 3 feet. If quarterback Matthew stafford is 8 1/2 inches tall on the poster, find his actual height.

Answers

Answer:

The actual height = 6.38 feet

Step-by-step explanation:

Given that a poster of the detroit lions football players uses a scale

of 4 inches = 3 feet

1 inch = 3/4 feet

Given that the poster's length:

[tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex] inch

We need to determine the actual height if quarterback Matthew Stafford is 8 1/2 inches tall on the poster.

As 1 inch = 3/4 feet

Thus, we need to multiply 8.5 inches by 3/4 to determine the actual height of the player.

Actual height = 8.5 × 3/4 feet

= 6.38 feet

Therefore, the actual height = 6.38 feet

Answer:

8 cm and 28 cm

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

(i)

Here A = 48, b = AB and h = DE = 6 , then

AB × 6 = 48 ( divide both sides by 6 )

AB = 8 cm

(ii)

Here A = 252, b = PQ = 9 and h = RT , then

9 × RT = 252 ( divide both sides by 9 )

RT = 28 cm

What is the slope of a line perpendicular to the line whose equation is
10x – 8y = -80. Fully reduce your answer.

Answers

Answer:

-4/5

Step-by-step explanation:

write the given equation in y=mx+b form, where m is the slope

10x-8y=-80

-8y= -10x-80 divide both sides by -8

y=(10/8)x+10

y=(5/4)x+10

m= 5/4 is the slope of the given function

the slope of an equation that is perpendicular is the negative reciprocal of the given one so is

m= -4/5

which point is closer to the x-axis (0.7, 21) or (0.77, 10)

Answers

Answer:

[tex]d_A=21[/tex][tex]d_B=10[/tex]

Therefore, point B is closer to the x-axis.

Please check the attached graph.

Step-by-step explanation:

We know that:

x-coordinate of any point P(x, y) gives its distance of that point from the y-axisy-coordinate of any point P(x, y) gives its distance of that point from the x-axis

Given the points

(0.7, 21)(0.77, 10)

Let us say

A(0.7, 21)B(0.77, 10)

FOR POINT A(0, 7)

As the y-coordinate of point A(0.7, 21) ⇒ y = 21

We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis

Thus, the distance of point A(0.7, 21) from the y-axis is 21 units.

i.e.

[tex]d_A=21[/tex]

FOR POINT B(0.77, 10)

As the y-coordinate of point A(0.77, 10) ⇒ y = 10

We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis

Thus, the distance of point B(0, 7) from the y-axis is 10 units.

i.e.

[tex]d_B=10[/tex]

[tex]d_A=21[/tex][tex]d_B=10[/tex]

Therefore, point B is closer to the x-axis.

Please check the attached graph.
