Can someone explain both of these ratios and answers to me?

Answer: First, you start with the equation:

9

x

+

4

=

472

Since four students rode in cars, you want to eliminate this part of the problem to find how many students actually rode in the buses

So you would subtract

4

from both sides and get:

9

x

=

468

Finally, you would divide both sides by

9

and get

52

students on each bus

Answer:

(1,7)

Step-by-step explanation:

SImply replace x by (1) in the expression to find the value of h:

h(1) = 4 (1) + 3 = 4 + 3 = 7

so for x = 1, h is 7 , which is written as: (1, 7)

Answer:

11. 6

12. The last option, A=1/4, B=7/16, C=5/8, D=3/4

Step-by-step explanation:

11. look at the denominators, and what do you see? I see that 11 is 88 divided by 8. So, let's divide the numerator by 8 as well! 48/8=6

12. 1/4 is half of 1/2, so it would be between 0 and 1/2, or A

     Same thing with 3/4 but this time in the middle of 1/2 and 1, or D

     5/8 is a little over 4/8, or 1/2, so C

     The last one left is 7/16, B

Answer:

y=-10x

Step-by-step explanation:

m=-10

For (1,-10) a=1  AND  b=-10

(use the formula y-b=m(x-a) to find the equation of the line)

y-b=m(x-a)

(sub the values of m (the slope) and a&b (from the point)

y - (-10) = (-10) × ( x - 1 )

(simplify)

y+10=-10(x-1)

(expand the bracket)

y+10=-10x+10

(subtract 10 for both sides)

y=-10x+10-10

(simplify)

y=-10x

Answer:

BC = 3

Step-by-step explanation:

If you picture A, B, and C on a line, the first part of the line, AB, has a length of 5 and the total line, AC, has a length of 8 . Means that the second part of the line, BC, has a length of 3 because you would add the length of both the first and second part of the line in order to get the total length of the line.

AB + BC = AC

5 + BC = 8

BC = 3

Answer: Neither

Step-by-step explanation:

When two lines are parallel, their slopes are the same.

When two lines are perpendicular, their slopes are opposite reciprocals. Opposite reciprocals equal -1 when multiplied together.

Equation #1: y = 4x + 3

The equation is in the form y = mx + b, so the slope is 4.

Equation #2: 4x + y = 3

We need to put this equation in slope-intercept form.

1) Subtract 4x from both sides

y = -4x + 3

The slope is -4.

-4 and 4 are neither equal nor opposite reciprocals, so they aren't parallel or perpendicular.

The slope of both lines is neither the same nor negative inverse of each other thus both lines will neither parallel nor perpendicular.

A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.

As per the given lines,

y =  4x +3

The slope-intercept form is given as y = mx + c where m is the slope.

By comparing slope m = 4

4x + y =3 → y = -4x + 3

Slope m = -4

Since slopes are not the same thus they will be not parallel.

Perpendicular lines slope's multiplication gives -1.

Since, 4 x (-4) ≠ -1 thus both will be not perpendicular.

Hence "The slope of both lines is neither the same nor negative inverse of each other thus both lines will neither parallel nor perpendicular".

Answer: 1. True 2. False

Step-by-step explanation: In question 1 they both equal 0.25 (5/20 and 7/28) but in question 2 they equal different values. 11/22=0.5 and 13/25 = 0.52.

Answer:

12

Step-by-step explanation:

Plug in for x first:

Y = -2(x+4) +6

Y = -2((-2)+4) +6

Y = -4 + 6

Y = 2

Then use Y to find W;

W = -3 -2y

W = -3 - 2(2)

W = -3(-4)

W= 12

Answer:

y=8 and w=13

Step-by-step explanation:

y=-2(x+4)

-2x-2=4 sooo...

y=4+4

y=8

then plug 8 into the equation for w

w=-3-2y

then you would get

w=-3-16

-3-16

w=13

We conclude that the slope of line 'n' is: m₂ = 10

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Given

The slope of line m is: m₁ = 10

It is stated that another line is parallel to line m.

Let m₂ be the slope of the 'n' line.

We know that when two lines are parallel, they have equal slopes.

i.e.  m₁ = m₂

as

The slope of line m is: m₁ = 10

and

The lines are parallel

so

The slope of line 'n' is: m₂ = 10

Therefore, we conclude that the slope of line 'n' is: m₂ = 10.
