Answer:

About 15

Step-by-step explanation:

The first two rows up from the bottom each contain 7 squares

The next row (3rd one up) is about 6 1/2

The fourth one up is about 5

The 5th one from the bottom is about 3

The total number is 7 + 7 + 6 1/2 + 5 + 3 = 28 1/2 squares.

Now what does that mean? Each square is 1/2 unit in the x direction by 1 unit in the y direction. The area of 1 "square" looking block is 1/2 * 1 = 1/2 unit^2

Since the number of squares on the graph = about 30 each one with an area of 1/2 unit^2, the answer should be 15.

The question is so intent on tricking you, it does not make clear what it wants. My answer is the second one down but don't be surprised if it is C

Are -4 ( x - 6) and -4 • x - 4 • 6 equivalent

tekilochka [14]

Answer:

$no$

Step-by-step explanation:

Lets solve the first half.

$-4 ( x - 6) = -4x + 24$

Second one:

$-4 times x - 4 times 6 = -4x -24$

Now compare.....Not the same right??

So your answer is: $no$

Hope this helps :)

Which equation matches the given points? (0, 7.6), (1, 6.2), (2, 4.8), (3, 3.4), (4,2)

Cerrena [4.2K]

The equation that matches the given points is g(x) = -1.4x + 7.6

The standard form of a linear equation is expressed as $g(x)=mx + b$

m is the slope of the line

b is the y-intercept:

Using the coordinate points (3, 3.4), (4,2)

$m=\frac{2-3.4}{4-3}\\m=\frac{-1.4}{1}\\m=-1.4$

Substitute m = -1.4 and the coordinate (4, 2) into the formula:

$2=4(-1.4)+b\\2=-5.6+b\\b=2+5.6\\b=7.6$

Get the required equation:

$g(x)=mx+b\\g(x)=-1.4x+7.6$

Hence the equation that matches the given points is g(x) = -1.4x + 7.6

Determine the measure of ∠Y. images attached

Gwar [14]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of ∠Y

To find the value of ∠Y we use tan

We have

$\tan(∠Y) = \frac{25}{20} \\ \tan(∠Y) = \frac{5}{4} \\ ∠Y = { \tan^{ - 1} } \frac{5}{4} \\ ∠Y = 51.34019...$

We have the final answer as

Hope this helps you

The system of equations when been placed in a matrix yields

$\left[\begin{array}{ccc}650&-1\\120&1\end{array}\right]\left[\begin{array}{ccc}x\\y\end{array}\right] =\left[\begin{array}{ccc}-175\\25080\end{array}\right]$

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the equation:

y = 650x + 175 and;

y = 25080 - 120x

Rearranging the equations gives:

650x - y = -175 and;

120x + y = 25080

Placing the equations in a matrix gives:

$\left[\begin{array}{ccc}650&-1\\120&1\end{array}\right]\left[\begin{array}{ccc}x\\y\end{array}\right] =\left[\begin{array}{ccc}-175\\25080\end{array}\right]$

The system of equations when been placed in a matrix yields

$\left[\begin{array}{ccc}650&-1\\120&1\end{array}\right]\left[\begin{array}{ccc}x\\y\end{array}\right] =\left[\begin{array}{ccc}-175\\25080\end{array}\right]$
