What is the equation in slope-intercept form of a line parallel to y=−2x+5 and passes through the point (4, 0)?
ser-zykov [4K]

Parallel lines have the same slope

The equation of the line is: y = -2x+8

The equation is given as:

y = -2x + 5

The slope intercept form of an equation is:

y = mx + b

Where:

m \to slope

By comparison,

m = -2

The line is said to be parallel to y = -2x + 5.

This means that the line has a slope of m = -2

The equation of the line is then calculated as:

y = m(x - x_1) + y_1

Where:

(x_1,y_1) = (4,0)

So, we have:

y = m(x - x_1) + y_1

Substitute values for m, x1 and y1

y = -2(x - 4) + 0

y = -2(x - 4)

Open brackets

y = -2x+8

Hence, the equation of the line is: y = -2x+8

See attachment for the graphs of y = -2x+8 and y = -2x + 5

A rectangle is 12m longer than it is wide. Its perimeter is 68m. Write and equation and show steps to find its length and width.
Galina-37 [17]

Answer:

  length: 23 m; width: 11 m.

Step-by-step explanation:

The perimeter of a rectangle is twice the sum of its length and width, so that sum is 34 m. Then you can write two equations in length and width:

  l + w = 34

  l - w = 12

Adding these together gives you ...

  2l = 46

  l = 23 . . . . . . divide by 2

Then the width is

  w = 23 -12 = 11

The length and width are 23 m and 11 m, respectively.

Which table contains the vertex of the graph represented by y=x^2-6x+4?
notka56 [123]

Answer:

Table B

Vertex is (3,-5)

Step-by-step explanation:

We are given with an equation of a parabola y=x^2-6x+4

Let is convert it into standard form of a parabola

y=x^2-6x+4

adding and subtracting 9 in the right hand side of the =

y=x^2-6x+9-9+4

y=x^2-2\times 3\times x+ 3^2-9+4

the first three terms of the right hand side forms the expression of square of difference

a^2-2 \times a \times b+b^2 = (a-b)^2

Hence

y=(x-3)^2-5

adding 5 on both sides we get

(y+5)=(x-3)^2

Comparing it with the standard equation of a parabola

X^2=4\times \frac{1}{4} \times Y

where X=x-3 and Y=y+5

The vertex of X^2=4\times \frac{1}{4} \times Y will be (0,0)

and thus vertex of

(y+5)=(x-3)^2 will be (3,-5)

Hence the Table B is our right answer

#1. Step one) we set find what we can multiply by 5 to get 20, so we divide 20 by 5.
20/5 = 4
Step two) we multiply the bottom denominator (8) by 4
8x4=32
Step three) leave the top numerator the same (20) and replace (d) with 32
Answer : 20/32
#2 step one) we divide 14 by 7
14/7 = 2
Step two) divide 10 by 2
10/2=5
Step three) replace z with 5
Answer) 7/5
#3 step one) divide 24 by 8
24/8=3
Step two) divide 21 by 3
21/3 = 7
Step three) replace (x) for (7)
Answer) 7/8
