Robert was deducted 22 points from his math test. He got 11 questions wrong. How many points was each question worth?

Answer:

The coordinates (12,7) would NOT be a solution to the system of linear inequalities shown below.

Step-by-step explanation:

If you do the graphing and you look at all your options of coordinates, (12,7) is the only one that is not in the shaded areas or in the lines of the inequalities. Therefore, (12,7) should be the answer to that question. :)

Answer:

x=-3

Step-by-step explanation:

there are three x's and five one's so the equation is 3x+5

on the other side there are 2 negative x's and 10 negative one's so the equation is -2x-10

set them equal to each other

3x+5=-2x-10

5x=-15

x=-3

Answer:

x-375

Step-by-step explanation:

First, we find a fourth of $1500.

1/4*1500=375

Then we know that you need to pay $375. We will represent the money right before you pay as x, or any variable you choose.

= x-375

Answer:

8 unit difference x, stays the same on y

Step-by-step explanation:

5 to -3 = 8 units

CS = x, and since AB = BC = CD = DA = 1cm -> SD = 1 - x

We see that angle DSP = angle APQ (because they simultaneously equal to 90 when added angle DPS)

So, triangle DSP = triangle APQ (equal hypotenuse - square side and equal angle.)

Similarly, we can prove triangle SCE and QBE in the same way

So, all 4 of the triangles are equal to each other.

-> SD = CE = BQ = AP = 1-x

Calculate the area of 4 triangles : [ x(1-x) : 2 ] x 4 = x(1-x) x 2

Area (PQRS) = 1 - [ x(1-x)] x 2 = 1 - 2x + 2x(squared) = [tex]2x^{2} -2x + 1[/tex]

ii) Half area of PQRS = [tex]x^{2} -x+1[/tex]

= [tex]x^{2} -\frac{1}{2} x-\frac{1}{2} x + \frac{1}{2} = x(x-\frac{1}{2} )- \frac{1}{2}(x-\frac{1}{2} ) + \frac{1}{4} = (x-\frac{1}{2})^{2} + \frac{1}{4}[/tex]

We have : [tex](x-\frac{1}{2}) ^{2}[/tex]

has the smallest value of 0 -> The smallest half value of PQRS = 1/4 -> The smallest value of PQRS = 1/2

Answer:

{7, 5, 2, 0}

Step-by-step explanation:

The domain is essentially all the [tex]x[/tex] values of the function, where the range is the value of [tex]h(x)[/tex].

So in order to solve this we simply plug in each number into the equation and get:

[tex]h(x)=|-2-5| = |-7|=7[/tex]

[tex]h(x)=|0-5| = |-5|=5[/tex]

[tex]h(x)=|3-5| = |-2|=2[/tex]

[tex]h(x)=|5-5|=|0|=0[/tex]

Therefore the range is: {7, 5, 2, 0}

Answer:

Let us divide the circle into 4 equal parts because they have told that 1/4 th part so there are 4 equal parts because,fractions represent equal parts of a whole or a collection.

Let us take a circle with centre 'O'

Now, the 1/4th part of circle is a sector with angle 90° & radius 3.5cm

We can find the area of sector in 2 methods

Method 1 :

Formula :

Here , r is radius & θ is the angle in sector where θ is measured in degrees

Hence , area of sector = 9.6cm²

Method 2 :

Formula:

Here , r is radius & θ is angle in sector where θ is measured in radians

First we have to convert 90° into radians

We know that π radians = 180°

90 ° = π/2 radians

Substituting

Hence , area of sector = 9.6 cm²

Step-by-step explanation:

y = ab^x

the coordinates of the point are x and y values.

so, we can express "a" by these values :

k = ab^h

a = k/(b^h) = k × b^-h

now we use this identity in the original equation and get

y = k × b^-h × b^x = k×b^(x-h)

and that is exactly the same as the proposed form.

What is below the question is what I mean.

Answer:

Domain: (-∞, -5) (-1, ∞)

Step-by-step explanation:

Note:

For f(x) > 0: See the points of x for which the graph of f(x) lies above the x-axis.

For f(x) < 0: See the points of x for which the graph of f(x) lies below the x-axis.

We need to find the domain of f(x) for which f(x) < 0

From the graph, we can tell:

f(x) < 0 on (-∞, -5) ∪ (-1, ∞)

Therefore: The domain on which the given graph f(x) is negative, is (-∞, -5) ∪ (-1, ∞)

Answer:

f [ x ] = [ x - 3] [ x + 8 ] = x^2 + 5x - 24

Step-by-step explanation:

f (x)=[ x - 3] [ x + 8 ]

x [ x + 8 ] -3[ x + 8 ]

x^2 + 8x - 3x - 24

x^2 + 5x - 24

Answer:

C

Step-by-step explanation:

The reason it is C is mainly because it is the only line with a negative slope. A negative slope this direct \. It is not A because that is a positive slope (/). It is not B because that line is undefined which means it would look like this x = 2. And D is wrong because that is a zero slope line which looks like this y = 5. So it is C.

Step-by-step explanation:

Given expression:

[tex](6x+9)^2-5[/tex]

When evaluating the expression for [tex]x=1[/tex], we need substitute 1 for the variable ([tex]x[/tex]) in the expression.

Evaluating the expression for [tex]x=1[/tex]:

[tex]\implies (6\cdot1+9)^2-5[/tex]

[tex]\implies (6+9)^2-5[/tex]

[tex]\implies (15)^2-5[/tex]

[tex]\implies 225-5[/tex]

[tex]\implies 220[/tex]

Answer:

Answer:

x = 10

Step-by-step explanation:

Y = x-5 has a slope of 1

3y - 6x = 0 is a clear linear equation with a Y-intercept of 0

y = -5 has no slope

x = 10 is a line going straight up and intersects the point (10, 0)

Which is an undefined slope
