Give expression: x2 - 5x + 1 evaluate if x = 7

Answer:

You answer is incorrect. The correct answer is -3, -2, -0.8, -1/10, 1/2, 0.8, 7.

Step-by-step explanation:

-3 is the smallest and 7 is the greatest.

1/2 is 0.5, which is smaller than 0.8.

-1/10 is -0.1, which is greater than -0.8.

-2 is greater than -3.

Answer:

Step-by-step explanation:

Alternate way of doing this using the point-slope formula.

Since y = -3x + 1 is in y=mx + b format, the slope is -3.

m = -3

The slope of the line perpendicular to y = -3x + 1 must be -(1/-3), or 1/3, since m1 = -1/m2.

Point - slope formula:

y - y1 = m (x - x1).

y - 4 = (1/3) (x - 1)

y - 4 = (1/3)x - 1/3

y = (1/3)x - 1/3 + 4

y = (1/3)x - 1/3 + 12/3

y = (1/3)x + 11/3

Answer:

y = 3x + 7

Step-by-step explanation:

If the line is perpendicular to y = -1/3x + 3, then the slope will be the reciprocal of 3.

y = 3x + b

To find b, plug in the known point of (-1, 4)

4 = 3(-1) + b

Solve.

4 = -3 + b

7 = b

Your equation is: y = 3x + 7

I think, if im wrong im sorry

Answer:

I would need some more information to determine this. See explanation.

Step-by-step explanation:

This equation is written in slope-intercept form, which indicates a line on a graph where the slope of the line is 3, and the y-intercept is -7. Knowing this, you could graph a line where the line crosses the y-axis at -7 (0, -7), and then use the slope to plot other points (such as 1,-4).

Another way to do this is to pick any number for x, and then solve for y. So if you are looking for any ordered pair on this line, pick a number:

Let's do x=5.

y = 3(5)-7

y = 15 - 7

y = 8. This means the ordered pair of (5,8) would satisfy the equation.

One more example, using the value of x=8

y=3(8) - 7

y = 24 - 7

y = 17

This means the ordered pair of (8, 17) would also satisfy the equation.

Answer:

Sum of 100 terms of the sequence = 15050

Step-by-step explanation:

Given expression which represents a sequence is,

[tex]\sum_{r=1}^{100}(3r-1)[/tex]

So the sequence will be,

2, 5, 8, 11, 14..........

So, the given sequence is an arithmetic sequence with,

First term of the sequence 'a' = 2

Common difference 'd' = 5 - 2 = 3

Sum of 'n' terms of an arithmetic sequence is given by,

[tex]S_n=\frac{n}{2}[2a+(n-1)d][/tex]

Here, n = number of terms

a = first term

d = common difference

[tex]S_{100}[/tex] = [tex]\frac{100}{2}[2(2)+(100-1)(3)][/tex]

      = 50[4 + 297]

      = 15050

Therefore, sum of 100 terms of the sequence = 15050

Answer:

The equation in slope-intercept form is [tex]y=\frac{1}{14}x[/tex].

Step-by-step explanation:

Given points are;

(-14, -1 ) and (0,0)

Slope of a line is given by;

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{0-(-1)}{0-(-14)}[/tex]

m = [tex]\frac{1}{14}[/tex]

General equation in slope intercept form is,

y = mx + b

Putting (-14, -1) and m = 1/14 in Equation to find b

-1 = [tex]\frac{1}{14}(-14) +b \\[/tex]

-1 = -1 + b

b = -1 + 1

b = 0

As y-intercept is 0, the equation in slope-intercept form would be

[tex]y = \frac{1}{14}x[/tex]

Hence,

The equation in slope-intercept form is [tex]y=\frac{1}{14}x[/tex].

Answer:

144 is the second power of 12

Step-by-step explanation:

Here, we want to get the power of 12 that 144 is

Mathematically;

144 = 12^2

What this mean is that we have to raise 12 to 2 to get 144

Thus, our answer is that 144 is the 2nd power of 12

Answer:

The answer is "Option A".

Step-by-step explanation:

Given line equation:

[tex]\to y+2=3(x-7)[/tex]

The standard equation of the line:

[tex]\bold{y-y_1=m(x-x_1)}\\\\[/tex]

Comparing the values:

[tex]x_1= 7\\\\y_1=-2\\\\m=3\\[/tex]

So, the points are: (7,-2) and the slope is: 3

That's why Choice "A" is correct.

Step-by-step explanation:

Answer: (a)  $ 36  (b) $ 236

Step-by-step explanation:

Simple interest = Principal x rate x Time

Given: Principal = $200 . rate = 6% = 0.06 ,

(a )Time = 3 years

Simple interest = 200 x 0.06  x 3

= $ 36

So,  the interest earned after 3 years  = $ 36

(b)  Balance in account after 3 years =  Principal  + Simple interest

= $ (200+36) = $ 236

So,  the balance after 3 years =  $ 236

Answer:

You will spend $27.35 on your date night.

Step-by-step explanation:

First you add your tickets. Yo would need two, 1 for you and one for your date.

$10.30+$10.30= $20.60

If you and your date both want your own candy bar you would need two as well.

$1.50+$1.50= $3.00

And finally you and your date will need one drink if you want to share so that will only be $3.75.

Inorderto find your total you need to add the the ticket total, candy total, and drink total.

$20.60+$3.00+$3.75= $27.35

Answer:

Where is the image?

Step-by-step explanation:

If it's 180 it should be halfway rotated

If it's 360 it should be completely rotated which means its back to where it started

If its 270 then it's close to being fully rotated

If its 90 then you just rotated it once which means that it was barely rotated.

Hope this helped a little, just lemme know when you put the image so I can help!

The  best describes the transformation of the given statement is the transformation was a 90° rotation about the origin.

A transformation is a function f, usually with some geometrical underpinning, that maps a set X to itself, i.e. f: X → X. The curve representing the graph either "moves to left/right/up/down" or "it expands or compresses" or "it reflects"

Given:

The given statement about the transformation.

According to given question we have

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

The rule for a rotation by 90° about the origin is (x,y)→(−y,x) .

Ex- Let A(2,3) ⇒A(2,-3)

Therefore, the  best describes the transformation of the given statement is the transformation was a 90° rotation about the origin.
