Answer:

1,5

Step-by-step explanation:

The translation can be seen in one line. You can see one going up by 5 and going to the right (not left as that would make it -1,5).

Answer:

(2, 7)

Step-by-step explanation:

(2, 7) are the coordinate which ordered pair is a solution to the following system of inequalities [tex]y \leq -x^2 + 8x \\[/tex] and [tex]y > x^2 - 3[/tex].

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

we want to find which ordered pair is a solution to the following system of inequalities.

[tex]y \leq -x^2 + 8x \\[/tex]

[tex]y > x^2 - 3[/tex]

The solution of a inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the inequality is the graph of all solutions of the system.

Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality.

[tex]y \leq -x^2 + 8x \\\\y = -x^2 + 8x\\\\y > x^2 - 3\\\\[/tex]

x = 2 and y = 7

Answer:

All Real Numbers

Step-by-step explanation:

This is a linear function, so the domain is All Real Numbers, or (-∞, ∞). In other words, the all numbers on the x-axis are defined on the graph. We have no points where x is undefined or imaginary. Domain contains all real numbers.

Answer:

23x-y=13

Step-by-step explanation:

we need to find the derivative with respect to x

In(y) =In(10^x)

In(y)=xIn(10)

now we have to take the derivative with respect to x

Therefore, y'=yIn(10)

where y'=10^xIn(10), Chain rule!

note: First derivative function always give us the gradient value when x value is substituted in

Therefore, at x=1, our gradient will be m= 10^1In(10)

Gradient m=23.0 to the nearest tenth

Finding the equation of the line

y-y1=m(x-x1)

y-10=23(x-1)

y-10=23x-23

y-23x=-23+10

y - 23x = -13

so, the equation of the line tangent line is

23x - y =13

Answer:

54=x

Step-by-step explanation:

2x+2=3x-52

this is because they are opposite alternating angles so now we can re arrange the equation.

54=x

Step-by-step explanation:

The both angles are vertically opposite angle so

[tex](2x + 2) = (3x - 52)[/tex]

By moving x on left side

[tex]2x - 3x = - 52 - 2[/tex]

So

[tex] - x = - 54[/tex]

Negative sign in both side are canceled so we got

[tex]x = 54[/tex]

b) The graph of both equations is attached

The intersection point of the lines is (100, 150)

It indicates 100 calendars and 150 posters to be donated to meet both of targets $600 and 250 items.

Answer:

Given equation:

[tex]3c+2p=600[/tex]

where:

If the company donating the calendars and posters said they would provide a total of 250 items then:

[tex]c+p=250[/tex]

To graph:

[tex]3c+2p=600 \implies p=300-\dfrac{3}{2}c[/tex]

[tex]\textsf{x-intercept}: \quad 300-\dfrac{3}{2}c=0 \implies c=200 \implies (200,0)[/tex]

[tex]\textsf{y-intercept}: \quad 300-\dfrac{3}{2}(0)=300 \implies (0,300)[/tex]

[tex]c+p=250 \implies p=250-c[/tex]

[tex]\textsf{x-intercept}: \quad 250-c=0 \implies c=250 \implies (250,0)[/tex]

[tex]\textsf{y-intercept}: \quad 250-0=250 \implies (0,250)[/tex]

Point of intersection (equate equations):

[tex]\begin{aligned}300-\dfrac{3}{2}c &=250-c\\50 & =\dfrac{1}{2}c\\ c & =100\end{aligned}[/tex]

[tex]p=250-100=150[/tex]

[tex]\implies \left(100,150}\right)[/tex]

The point of intersection tells us that they need to sell 100 calendars and 150 posters to reach their goal of raising $600.  Therefore, the company needs to provide 100 calendars and 150 posters (or 250 items in the ratio of calendars to posters of 2 : 3).

Answer:

x = 3/2 or x = -5/4

Step-by-step explanation:

Solve for x over the real numbers:

8 x^2 - 2 x - 15 = 0

Using the quadratic formula, solve for x.

x = (2 ± sqrt((-2)^2 - 4×8 (-15)))/(2×8) = (2 ± sqrt(4 + 480))/16 = (2 ± sqrt(484))/16:

x = (2 + sqrt(484))/16 or x = (2 - sqrt(484))/16

Simplify radicals.

sqrt(484) = sqrt(4×121) = sqrt(2^2×11^2) = 2×11 = 22:

x = (2 + 22)/16 or x = (2 - 22)/16

Evaluate (2 + 22)/16.

(2 + 22)/16 = 24/16 = 3/2:

x = 3/2 or x = (2 - 22)/16

Evaluate (2 - 22)/16.

(2 - 22)/16 = -20/16 = -5/4:

Answer: x = 3/2 or x = -5/4

Answer: 11

Step-by-step explanation:

The number of bags that they will need if each bag contains 500 cubic inches of confetti is 20,000

One bag contains 500 cubic inches of confetti.

Therefore,

1 bag = 500 inches³

The student need to fill 100 containers with the bag.

Each container can accomodates 100,000 cubic inches.

Therefore,

1 bag = 500 inches³

100,000inches³ = 1 container = 200 bags

Therefore,  

100 containers will contain 20, 000 bags of confetti.

Answer:

660 ft³

Step-by-step explanation:

The way I'm thinking of it, we can think of it as a triangle and then extruding out from that triangle for the length.

First, the triangle:

area = base * width / 2 = 12 * 10 / 2 = 60 ft²

volume = the triangle for the length

the length is 11 feet,

so we extrude that triangle for 11 feet to get

60 ft² * 11 ft = 660 ft³

we multiply 10 ft by 12 ft by 11 ft. there are 3 instances of ft, so the corresponding exponent is therefore ³.

another way to think of the extrusion is like a rectangular prism, the formula for a rectangular prism's volume is length * width * height. we're extruding from the bottom rectangle for the whole of the height, so we multiply the area of the bottom triangle (length * width) by height.

Answer:

B)   A = (-1, 0),  B = (1, 0)

Step-by-step explanation:

If the transformation of AB to A'B' is (x+4, y-3),

then the transformation of A'B to AB is the reverse: (x-4, y+3)

Given

A' = (3, -3)  →  A = (3-4, -3+3) = (-1, 0)

B' = (5, -3)  →  B = (5-4, -3+3) = (1, 0)

Therefore:

A = (-1, 0),  B = (1, 0)
