(-2, 4)

Answers

First, make a coordinate plane.
-2,4 is the given coordinate. To find this coordinate, look at the X axis, first. Find -2. Then go up on your -2 line, and find 4, You'll be at the coordinate, -2,4.
Now, 6 units down from coordinate -2,4,is, -2,-2
all you have to do, is move your finger down 6 lines. You will be at the coordinate, -2,-2.
-2,-2 is the answer.

Consider the following graph of a quadratic function. Which of the statements are true? Select all that apply.
A. The function is decreasing over the interval x<-1

B. The range of the function is all real numbers.

C. The function is increasing over the interval x<-1

D. The domain of the function is all real numbers

E. The function has a relative minimum at (-1,5)

Answers

Answer:

Option C,D and E are correct.

Step-by-step explanation:

Clearly from the graph we could say that it is a graph of a quadratic function.so we will work on each of the following options:

Clearly from the graph we could see that the graph is increasing on both the sides of -1.

Hence, option A is wrong. ( The function is decreasing over the interval x<-1).

As the function is a quadratic function hence the range contains all the real numbers greater than or equal to 5 below 5 it won't take any value.

Hence option B is wrong.(The range of the function is all real numbers).

clearly we could see that the function is increasing in the interval x<-1.

Hence, option C is correct.

The function is defined for all of the real numbers.

Hence option D is correct. (The domain of the function is all real numbers).

Clearly from the graph we could see that the function has minimum value at -1 and the graph is increasing before and after that.

Hence, option E is correct.( The function has a relative minimum at (-1,5) ).

Answers

The best solution would be about 2.7.

Answer:

x=2.732

Step-by-step explanation:

Given are two functions

f(x) = 2x-3 and g(x) = [tex]x^2-5[/tex]

WE have to find the approximae value when these two funcitons are equal

Since we are asked to find only positive value we can refer table and do

f(2) >g(2) but f(3)<g(3) Hence there is one solution between 2 and 3.

f(2.5)>g(2.5). So the root lies between 2.5 and 3 since change of sign takes place here

The distance between two towns is 12 5/8 miles. Mr.Lang has driven 4 5/12 miles of distance. How much farther does he have left to go?

Answers

All you have to do is subtract the total distance from the distance he has already driven.

[tex]\sf 12\dfrac{5}{8}-4\dfrac{5}{12}[/tex]

Convert them to improper fractions. We do this by multiplying the denominator to the whole number, adding it to the numerator, which becomes the numerator, and we keep the denominator the same.

[tex]\sf\dfrac{101}{8}-\dfrac{53}{12}[/tex]

To subtract fractions we need a common denominator. The least common multiple of 8 and 12 is 24. Convert both fractions to denominators of 24, find out how many times the current denominator goes into 24, then multiply that number to both the numerator and denominator:

[tex]\sf\dfrac{303}{24}-\dfrac{106}{24}[/tex]

Now we can subtract the numerators and keep the denominator the same:

[tex]\sf\dfrac{197}{24}[/tex]

Convert back to a mixed number. Twenty-four goes into 197 eight times. 24 * 8 = 192. 197 - 192 = 5. So we have 8 whole 24s and 5/24 left, or:

[tex]\boxed{\sf 8\dfrac{5}{24}}[/tex]

The formula h-15=3.2t gives the height h in inches of a plant t weeks after planting. Which is the rate at which the plant height is increasing?

Answers

Answer: The height is increasing at a rate of 3.2 inches per week.

To find this, you should put the equation in slope-intercept form. This can be done by adding 15 to both sides of the equation.

You will get h = 3.2t + 15

The value in front of the t is the slope. In this case, it is inches per week.

Answer: y= -1/2 + 1

Step-by-step explanation: To solve this problem, first determine the slope of your line. Since perpendicular lines have slopes that are opposite reciprocals of each other,we know that the slope is -1/2. Then plug your slip (-1/2) and point (6,-2) into the equation y=mx+b to solve for b. The resulting value for b is 1.

Which of the following inequalities matches the graph?

Answers

A vertical line has an equation of the form x = k, where k is the x-coordinate of all points on the line.
You have a vertical line. It passes through the point (-3, 0), so for this line, k = -3.
The vertical line has equation x = -3.
The line is dashed, not solid, so you have either < or >, but not <= or >=.
Also, notice the shading is to the left of x = -3, so all values of x are less than -3.
The inequality is

x < -3

Are the triangles similar? If they are, identify the similarity ratio.
A. Yes, the similarity ratio is 1:4
B. Yes, the similarity ratio is 1:5
C. Yes, the similarity ratio is 1:3
D. No, the triangles are not similar

So, I feel like D is out of the equation. Because the only difference is the shape and size. I was staring to lean towards C. Can anyone give me their two cents on this?

Answers

Answer: C is the correct answer.

Step-by-step explanation:

Answer:

C. Yes, the similarity ratio is 1:3

Step-by-step explanation:

The two triangles are similar because the corresponding sides are proportional.

The length of the side of the smaller triangle that is 3 units corresponds to the length of the side of the bigger triangle that is 9 units.

These two sides are in the ratio [tex]3:9[/tex].

When we simplify this ratio, we get [tex]1:3[/tex].

The length of the side of the smaller triangle that is 6 units corresponds to the length of the side of the bigger triangle that is 18 units.

These two sides are in the ratio [tex]6:18[/tex].

When we simplify this ratio, we get [tex]1:3[/tex].

The length of the side of the smaller triangle that is 5 units corresponds to the length of the side of the bigger triangle that is 15 units.

These two sides are in the ratio [tex]5:15[/tex].

When we simplify this ratio, we get [tex]1:3[/tex].

Therefore the similarity ratio is [tex]1:3[/tex].

Which steps should be followed to use a scale drawing and a new scale to find the new length of a soccer field? Add the numerator of the new scale to the old length to get the new length. Subtract the new length from the old length to find the difference in lengths. Write a proportion using the new scale as the first ratio. Set the first ratio equal to the ratio of the length of the original field compared to a variable that represents the new length of the field. Solve the proportion to find the new length of the field. Write a ratio comparing the scale drawing length to the actual length of the field, and simplify.

Answers

Set the first ration equal to the ratio of the length of the original field compared to a variable that represents the new length of the field. Solve the proportion to find the length of the field.

Solving proportions with a missing variable always involves setting the proportions equal to each other, and then solving for the missing variable.

Which statement is NOT true?

F. A set of ordered pairs that describes a function cannot have any y-value repeated.

G. A table of values describes a function if all the x-values are different.

H. A mapping is a function if each x-value is paired with exactly one y-value.

J. A graph describes a function if no point on the graph lies directly above or below another of the graph.

Answers

The answer is F. A set of ordered pairs that describes a function cannot have any y-value repeated.

~~

Why??

F - it can be a function even if a y - value repeats itself its the x - values that cannot repeat in order to be a function.

G - this is true as stated above.

H - a mapping is a function if each x - value is paired with only one y - value. If an x - value was paired with multiple y - values then its the same thing as repeated x - values.

J - this is true. To check if a graph is a function try the vertical line test. Simply take a ruler holding it vertically ( up and down ) and place it over a point on the graph. If there is another point lined up with the first one ( above or below ), then it is NOT a function.
