Answer:

h(-4) = -2

Step-by-step explanation:

h(x) = −2x − 10

Plug in x = -4 into the function h(x) = −2x − 10

h(-4) = −2(-4)  − 10

h(-4) = 8 - 10

h(-4) = -2

Answer:

The answer is -2

Step-by-step explanation: If h(x)= -2(-4)-10

h(x)=8-10

h(x)=-2

You must make a [tex]\frac{part}{whole}[/tex] proportion.

92% is part of 100%

540 would need to be the 92% of the plant bought. That means 540 is the part and the whole would be the unknown (let's make this x)

Set up your proportion like so...

[tex]\frac{540}{x} =\frac{92}{100}[/tex]

Cross multiply...

92x = 540 * 100

92x = 54000

Isolate x by dividing 92 to both sides...

92x/92 = 54000/92

x = 586.9565

Since you can't buy a decimal of a plant you will have to round this number up to the next whole number...

587

To have 540 of the plants arrive alive the nursery owner must order 587 plants

Answer: its c.

Step-by-step explanation:

The graph will show an initial value that is lower on the y-axis.

aka c.

Answer:C

Step-by-step explanation:

The larger number is 71 and the smaller number is 19.

Two equations can be derived from the question:

x + y = 90 equation 1

x = 14 + 3y equation 2

The larger number would be represented with x and the smaller number would be represented with y.

Substitute for x in equation 1

14 + 3y + y = 90

Add similar terms

14 + 4y = 90

Make y the subject of the formula

4y = 90 - 14

4y = 76

y = 76 / 4 = 19

Substitute for y in equation 1

x + 19 = 90

x = 90 - 19

x = 71

The sum of numbers is the addition of the numbers.

The numbers are 19 and 71

Let the two numbers be x and y, where y is greater than x.

So, we have:

[tex]\mathbf{y = 3x + 14}[/tex]

The sum of the numbers is:

[tex]\mathbf{x +y = 90}[/tex]

Substitute [tex]\mathbf{y = 3x + 14}[/tex]

[tex]\mathbf{x +3x + 14 = 90}[/tex]

[tex]\mathbf{4x + 14 = 90}[/tex]

Subtract 14 from both sides

[tex]\mathbf{4x = 76}[/tex]

Divide both sides by 4

[tex]\mathbf{x = 19}[/tex]

Substitute [tex]\mathbf{x = 19}[/tex] in [tex]\mathbf{y = 3x + 14}[/tex]

[tex]\mathbf{y = 3(19) + 14}[/tex]

[tex]\mathbf{y = 71}[/tex]

Answer:

C. y = -1/2 x

Step-by-step explanation:

Slope = (-2 - 0)/(4 - 0) = -1/2, b = 0

So

y = -1/2 x

Answer:

C

Step-by-step explanation:

By observation, we can see that the slope of the graph is negative (i.e the graph goes from top left to bottom right) hence the number attached to the x-term must be negative. We can see that E and F have positive x-terms, hence these cannot be correct.

Now we are left with A, B, C, D as possible choices.

you are given that point (4, -2) is on the line, hence when x = 4, y must = -2.

Use this knowledge to test each of A, B, C, D to see which one gives y = -2 when we try x = 4

When x = 4

A) -[tex]\frac{1}{4}[/tex] (4) = -1 ≠ -2 (wrong)

B) -2 (4) = -8 ≠ -2 (wrong)

C) -[tex]\frac{1}{2}[/tex](4) = -2 (correct)

D) -4(4) = -16 ≠ -2 (wrong)

Your answer is B) -1/2

One way of finding this answer is by using the slope equation (y2 - y1)/(x2 - x1) and substituting in the coordinates on the line. This gets you

(2 - 3)/(4 - 2) = -1/2

Another way is to find the slope by looking at the graph, and seeing that it must be negative because it slopes downwards to the right instead of up, and that it must be 1/2 because for every 1 unit you go down, you go 2 across, which means your y/x is 1/2.

Answer:

D

Step-by-step explanation:

Answer:

Step-by-step explanation:

The first graph (the parabola opening down) represents an even function, since this graph is symmetric with respect to the y-axis.

Step-by-step explanation:

For an even function we have f(x) = f(-x)

In the given graphs let us substitute values

In first graph

            f(2) = 0

            f(-2) = 0

            So f(2) = f (-2)

            Graph is even

In second graph

            f(2) = 0

            f(-2) = 4

            So f(2) ≠ f (-2)

            Graph is not even

Answer:

[tex]y=2x+1[/tex]

Step-by-step explanation:

Let the linear equation be [tex]y=mx +b[/tex].

The slope of a linear equation is the same as the rate of change of that linear linear equation.

The rate of change of y with respect to x is given in the question as 2.

[tex]\implies m=2[/tex]

We substitute this slope to obtain the partial equation;

[tex]y=2x+b[/tex]

If the coordinate (0,1) is a solution, then it must satisfy this equation.

[tex]\implies 1=2(0)+b[/tex]

[tex]\implies 1=b[/tex]

The required equation is:

[tex]y=2x+1[/tex]

the equation of the line is y = 2x + 1.

The student asked for the equation of a linear function where the rate of change of y with respect to x is two, and the coordinate (0,1) is a solution. This means the slope (m) of the line is 2, and it passes through the point (0,1). The general form of a linear equation is y = mx + b, where m is the slope, and b is the y-intercept.

Since we know the slope is 2 and it passes through (0,1), we can substitute these values into the equation to find b:
1 = 2(0) + b.
So, b = 1. Therefore, the equation of the line is y = 2x + 1.

Step-by-step explanation:

-12d ≥ -6

d  ≥ -6/-12

d  ≥ 1/2.

The Inequality represents all possible solutions of -12 d ≥ (-6) is d ≤ 1/2.

Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

We have the inequality,

-12 d ≥ (-6).

Now, solving the inequality

Divide both side by 12

(-12 d )/ 12 ≥ (-6)/ 12

-d ≥ -1/2

Now, multiply both side by (-1), we get

d ≤ 1/2.

Answer: 2nd, 3rd, and 5th are true

Step-by-step explanation:

The first statement cannot be true, if n ≥ 5, which is given, then ZY must be greater than XY

The second statement must be true, as long as n ≥ 5, ZY will always be greater than XZ and XY, and therefore, the angle opposite to ZY will always be the greatest angle, so X is the largest angle

The third statement must be true for the same reasoning as the second statement. The side opposite to angle Z will always be greater than the side opposite of angle Y, meaning that angle Z will always be greater than angle Y (assuming n ≥ 5).

The fourth statement is false, we already proved that X is the largest angle and XZ is not opposite of angle X.

The fifth statement is true, XZ will always have the lowest value as long as n ≥ 5.

All the correct statements regarding the sides and angles of the triangle are,

⇒ Angle X is the largest angle.

⇒ Angle Z is greater than angle Y.

⇒ XZ is the shortest side.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Triangle XYZ is shown,

where n ≥ 5

Now, We get;

For n = 5;

XY = n + 4 = 5 + 4  = 9

YZ = 2n = 2 x 5 = 10

ZX = n - 2 = 5 - 2 = 3

Hence, We get;

⇒ ZX < XY < YZ

And, ∠X > ∠Z > ∠Y

Thus, All the correct statements regarding the sides and angles of the triangle are,

⇒ Angle X is the largest angle.

⇒ Angle Z is greater than angle Y.

Answer:

The inequality would be 4x + 9 ≥ 0

Step-by-step explanation:

You could use this inequality to solve the domain as any number can be put into this equation as long as it doesn't make what is under the square root symbol (4x + 9) negative. Therefore, you can build this inequality and solve from there if you would like.

For this case we have a function of the form [tex]y = f (x)[/tex], where:

[tex]f (x) = \sqrt {4x + 9} +2[/tex]

We must look for the domain of the function. By definition, the domain of a function is given by all the values for which the function is defined.

So, for the given function to be defined, the argument of the root must be positive, that is:

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

here d = - 4 and a₇ = 4, hence

a₁ + (6 × - 4) = 4

a₁ - 24 = 4 ( add 24 to both sides ), hence

a₁ = 28

a₂ = 28 - 4 = 24

a₃ = 24 - 4 = 20

Answer:

B.

Step-by-step explanation:

The answer is B. The problem says that the slope is 2 and it as the points (3,10) on its line. When looking at the graph, you can see that the line crosses at four on the y-intercept which is why four will be your constant. So, your equation in slope intercept form will become y=2x+4. With this, you can start eliminating the given answers.

You can immediately eliminate c and d because the 2 is negative when it isn't in its slope form. It leaves you with a and b.

When looking at both a and b you now have to look at what your y will become when you sinplify both of them. In choice a, the 2 multiplies with the 3 and gives you 6. Since you have to leave the y by itself you have to subtract 10 from both sides which will leave you with -4. Since your y-intercept isn't negative you know that a isnt the ansewr.

When checking b, you multiply the 2 and -3 to get -6. Since you have to leave the y by itself, you add 10 to each side and end up with 4 which is the same number that crosses the y-axis. and that is how you know it's the right answer.

Hope this helps Have a nice day

There's the tangent secant angle theorem which says the measure of angle B is half the difference of the two intercepted arcs.  That means

58 = (1/2) (210 - x)

116 = 210 - x

x = 94

Answer: A

That's not a very intuitive answer.  Let's see if we can see why.  Let's call the center of the circle O and the unlabeled intersection at the top D.

Angle DOC=210 degrees the long way, that's what an arc measure means

Angle DOC=360-210=150 degrees the short way

We have angle BCO=90 degrees because it's a tangent.

So angle BDO is the fourth angle in a quadrailateral BCDO

BDO = 360 - DBC - BCO - DOC = 360 - (58 + 150+90) = 62 degrees

ADO is isosceles, with two radii for sides.  So DAO=62 degrees

That leaves DOA = 180 - 62 - 62 = 56 degrees

Angle AOC = x

x + arc AD = DOC

x + 56 = 150

x = 94

That checks.

The slope of the airplane's ascent is calculated using the rise over run formula and is 3 / 8 or 0.375.

Explanation:

The slope of the airplane's ascent can be calculated by the ratio of the rise over the run. In this case, the airplane climbs 15 feet up (rise) for every 40 feet it moves forward (run). Therefore, using the formula slope = rise / run, we can determine that the slope of the airplane's ascent is 15 / 40, which simplifies to 3 / 8 or 0.375.
