Answers
Answer:
https://brainly.com/question/24983242 help
Step-by-step explanation:
12 + 4[5% - 4(x + 5)] = 7 - 5x
12 + 4•(5% - 4•(x + 5)) = 7 - 5•x
11x = -55
x = -5
Answer:
[tex]x = - \frac{34}{5} [/tex]
Step-by-step explanation:
12 + 4 (5% - 4(x + 5)) = 7 - 5x
12 + 4 (5/100 - 4x - 20) = 7 - 5x
12 + 4 (-399/20 - 4x) = 7 - 5x
12 - 399/5 - 16x = 7 - 5x
-399/5 - 16x = 7 - 5x
-16x + 5x = 7 + 339/5
-11x = 374/5
x = -34/5

Answer:
neither (y=(x-.5)^2-6.25)linear (y=4x+6)exponential (y=3^x)Step-by-step explanation:
1. Successive y-values have neither a common difference nor a common ratio. The table is neither linear nor exponential.
__
2. Successive y-values differ by 4. The table is linear.
__
3. Successive y-values have a ratio of 3. The table is exponential.
_____
Additional comment
For evenly-spaced x-values, the y-values will have a common difference for a linear function, and a common ratio for an exponential function.
If the table can be represented by a polynomial function, the level at which differences are constant will tell the degree of the polynomial. First differences are constant for a degree 1 (linear) function. Second differences are constant for a degree 2 (quadratic) function. This is the case in Table 1, where second differences are 2.

21. You place a mat around a 25 in by 21 inch painting as shown. The mat
is twice as wide at the left and right of the painting as it is at the top an
bottom of the painting. The area of the mat is 714 square iinches (note:
the area of the border). How wide is the mat at the left and right of the
painting? At the top and bottom of the painting? (P.264 #66)
Answers
Using a quadratic equation according to the area of the rectangular mat, it is found that:
At the top and bottom of the painting, the width is 0.654 inches.At the left and right of the painting, the width is of 1.308 inches.The area of a rectangle of length l and width w is given by:
[tex]A = lw[/tex]
In this problem:
The length of the figure is of [tex]l = 25 + 4x[/tex].The width of the figure is of [tex]w = 21 + 2x[/tex].Area of 714 square inches, thus:[tex]lw = 714[/tex]
[tex](25 + 4x)(21 + 2x) = 714[/tex]
[tex]8x^2 + 134x + 525 = 714[/tex]
[tex]8x^2 + 134x - 189 = 0[/tex]
Which is a quadratic equation with [tex]a = 8, b = 134, c = -189[/tex].
The, to find the widths of the mat, we have to first find the value of x, solving the quadratic equation.
[tex]\Delta = 134^2 - 4(8)(-189) = 24004 [/tex]
[tex]x_{1} = \frac{-134 + \sqrt{24004}}{2(8)} = 0.654[/tex]
[tex]x_{2} = \frac{-134 - \sqrt{24004}}{2(8)} = -9.03[/tex]
We are interest in the positive value of x, so x = 0.654.
At the top and bottom of the painting, the width is of 0.654 inches.[tex]2(0.654) = 1.308[/tex]
At the left and right of the painting, the width is of 1.308 inches.A similar problem is given at https://brainly.com/question/14099239

Answers
Answer:
465 I think is the answer
% / 100 = Part / Whole
replace the given values:
85 / 100 = Part / 620
Cross multiply:
= 85 x 620 = 100 x Part
= 52700 = 100 x Part
Now, divide by 100 and get the answer:
Part = 52700 / 100 = 527
