Step-by-step explanation:

<em>1).</em>

(a). Yes, the graph is linear.

(b). Rate of change is a slope m, m = (60 - 80) / (10 - 0) = - 2

<em>2).</em> Graph is not proportional, because y-intercept is (0, 80) and not (0, 0)

pentagon [3]

Fraction -> Decimal

4/5 = 0.8

1/8 = 0.125

Decimal -> Percent

0.22 * 100% = 22%

0.47 * 100% = 47%

Percent -> Fraction

34% / 100 = 0.34 = 17/50

25% / 100 = 0.25 = 1/4

Fraction -> Percent

1/3 = 0.33... * 100% = 33.3%

2/5 = 0.4 * 100% = 40%

Decimal -> Fraction

0.65 = 65/100 = 13/20

0.4 = 4/10 = 2/5

Percent -> Decimal

81% / 100 = 0.81

4% / 100 = 0.04

Best of Luck!

|1/4 x +2| -3 =5 solve for x and graph on number line
kaheart [24]

The value of x on the number line is 24 and - 40

A number line in elementary mathematics is a representation of a graduated straight line that acts as an abstraction for real numbers, represented by the letter R. It is assumed that every point on a number line corresponds to a real number, and that every real number corresponds to a point.

When seen as a geometric space, namely the one-dimensional Euclidean space, the number line, also known as a real line in advanced mathematics, is technically defined as the set R of all real numbers. It can be conceptualized as a linear continuum, metric space, topological space, vector space (or affine space), measure space, or topological space.

The given equation is

|\frac{1}{4}x+2 | -3=5

Solving the equation:

or,|\frac{1}{4}x+2 | =5+3\\or,|\frac{1}{4}x+2 |=8\\or,\frac{1}{4}x+2=\pm8\\or,x+8=\pm32\\or,x=-8\pm32

Now we take the two separate values of x:

either x=-8+32 or x=-8-32

or,x=24 or x=-40

The value of x is 24 and - 40.

Please help fast! give me the equation
uranmaximum [27]

\begin{bmatrix}x=\frac{\pi }{2}+2\pi n\\ x=\frac{3\pi }{2}+2\pi n\\ x=\frac{3\pi }{4}+\pi n\\ x=\frac{7\pi }{4}+\pi n\end{bmatrix}

\begin{bmatrix}\frac{3\pi }{2}+2\pi n=\frac{\pi }{2}+2\pi n\\ \frac{3\pi }{2}+2\pi n=\frac{3\pi }{4}+\pi n\\ \frac{3\pi }{2}+2\pi n=\frac{7\pi }{4}+\pi n\end{bmatrix}

\pi =0

A person plans to invest a total of $3500 in one bank account at 2.2% annual interest and another bank account at 17% annual int
jeka57 [31]

Answer:

$435.3

Step-by-step explanation:

Assuming simple interest

Interest, I=Pi/100 where P is principal amount and i is rate of interest in percentage

For $3500, the interest will be 3500*2.2/100=$77

From total target of $151, the person is less 151-77=$74

Taking x as principal and rate of interest as 17% then

0.17x=74

X=74/0.17=$435.2941176470

Rounded off as $435.3
