Answer: D) On a coordinate plane, a solid straight line has a negative slope and goes through (0, 3) and (1, negative 1).

On a coordinate plane, a solid straight line has a negative slope and goes through (0, 3) and (1, negative 1). Everything to the right of the line is shaded.

Suppose there is inequality given as: y ≥ f(x)

The region it covers is the region of value pairs (x,y) for which this inequality holds true.

We've to draw the region covered by it.

For a function y = f(x), there is y > f(x) on one side of the graph of the function y = f(x) in XY plane, and on other side there is y < f(x).

A manufacturing machine has two processes. One of them is repeated 4 times and the second only once. The entire cycle can take no longer than 3 minutes.

Let t be the time of the first process in minutes

s be the time of the second process in minutes

we know that the time of the first process multiplied by 4 (because is repeated 4 times) plus the time of the second process multiplied by 1 (because is repeated only once) must be less than or equal to 3 minutes

So, The inequality that represents this situation is

[tex]4t + s\leq 3[/tex]

The y-intercept of the solid line is the point (0,3)

The x-intercept of the solid line is the point (0.75,0)

The slope of the solid line is negative m=-4

On a coordinate plane, a solid straight line has a negative slope and goes through (0, 3) and (1, negative 1). Everything to the right of the line is shaded.

Answer:

  B.  6.8

Step-by-step explanation:

The drawing measure can be found using the proportion ...

  drawing/actual = 2 in/(5 ft) = x/(17 ft)

Multiplying by 17 ft gives ...

  x = (2 in)(17/5) = 6.8 in

The drawing of the kitchen will be 6.8 inches.

Answer:

The average rate of change of the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex] is -1

Step-by-step explanation:

We are given the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex]

We need to find average rate of change.

The formula used to find average rate of change is : [tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}[/tex]

We have b=-1 and a=-11

Finding g(b) = g(-1)

[tex]g(x)=x^2+10x+18\\Putting \ x=-1\\g(-1)=(-1)^2+10(-1)+18\\g(-1)=1-10+18\\g(-1)=9[/tex]

Finding g(a) = g(-11)

[tex]g(x)=x^2+10x+18\\Putting \ x=-11\\g(-11)=(-11)^2+10(-11)+18\\g(-1)=121-110+18\\g(-1)=29[/tex]

Finding average rate of change

[tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}\\Average \ rate \ of \ change=\frac{9-29}{-1-(-11)}\\Average \ rate \ of \ change=\frac{-10}{-1+11}\\Average \ rate \ of \ change=\frac{-10}{10}\\Average \ rate \ of \ change=-1[/tex]

So, the average rate of change of the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex] is -1

Answer:

Option A: 0.07c = 1.26 is the correct answer

Step-by-step explanation:

Given that the price of shirt is denoted by c.

Given that the sales tax is 0.07 times of the cost of shirt.

Mathematically it can be written as:

[tex]Sales\ tax=0.07c[/tex]

Now it is also given in the statement that the sales tax is $1.26

Putting this value in the above equation

[tex]1.26 = 0.07c[/tex]

As we have to find the cost, dividing both sides by 0.07

[tex]\frac{1.26}{0.07} = \frac{0.07x}{0.07}\\c = \frac{1.26}{0.07}[/tex]

Hence, we saw that the intermediate equation was: 1.26 = 0.07c

So,

Option A: 0.07c = 1.26 is the correct answer

Answer: A. 0.07 · c = 1.26

Step-by-step explanation:

Sales tax (0.07) x cost (c) = price (1.26)

Answer: Yes, there is an ordered pair solution

The quick way we can see this without having to graph or do any algebra is to look at the two slopes of the lines.

y = x+1 has slope of 1

y = -x+5 has slope of -1

Recall that y = mx+b has slope m.

The two different slopes (1 and -1) indicate the lines are not parallel, so they must intersect exactly once. This intersection is the where the solution is located.

Step-by-step explanation:

Answer:

36 degrees

Step-by-step explanation:

180 - 58 = 122 degrees

122 - 90 = 32 degrees

32 + 4 = 36 degrees

Answer:

s = 36

Step-by-step explanation:

These lines is 180° in total and the one that is a right triangle has 90° and there is 58° on one so, 180 - 90 - 58 = 32.

32° = s - 4°

32 + 4 = s

36° = s°

Answer: 1/3

From the question, we are informed that when Jake volunteers at the animal shelter, he divides two-thirds cup of cat food equally between 2 cats.

The amount of food that is given to each cat will be:

= 2/3 × 1/2

= 1/3

Each cat gets 1/3 of the food

Answer:

the guy above me is verry correct

Step-by-step explanation:

Answer:

-2y = 4 - x

2y = x - 4

y = 1/2x - 2

1/2 is the slope of both lines.

y = mx + b

Substitute the given point and the common slope

2 = 1/2 x 2 + b

2 = 1 + b

b = 1

y = 1/2x + 1

The equation of the line that passes through the point

(2, 2) and is parallel to the line x - 2y = 4 is y = 1/2x + 1 or 2y = x + 2.

plz give me the brainliest i really need it

Answer:

x - 2y = - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x - 2y = 4 ( subtract x from both sides )

- 2y = - x + 4 ( divide all terms by - 2 )

y = [tex]\frac{1}{2}[/tex] x - 2 ← in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]

Parallel lines have equal slopes, thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, 2) into the partial equation

2 = 1 + c ⇒ c = 2 - 1 = 1

y = [tex]\frac{1}{2}[/tex] x + 1 ← equation in slope- intercept form

Multiply through by 2

2y = x + 2 ( subtract 2y from both sides )

0 = x - 2y + 2 ( subtract 2 from both sides )

- 2 = x - 2y, that is

x - 2y = - 2 ← equation in standard form

Answer:

B. The quadrilaterals are all the same size and shape.

Step-by-step explanation:

Lauren was drawing a tower ONLY using SIMILAR quadrilaterals, so since that is, since the quadrilaterals are similar, then they must have the same size and shape.

The statement i.e. true for quadrilaterals should be

B. The quadrilaterals are all the same size and shape.

A quadrilateral refer to the closed shape also it is the type of polygon that comprises of four sides, four vertices, and the four angles. Here the sum of the interior angle should be equivalent to the 360 degrees.

Therefore, we can conclude that the second option is correct.
