what is the y-intercept of y=-3x-2

Answer:

6. composite figure

7. 60+432=492

Answer:

0.42

Step-by-step explanation:

The original price of the old hardcover books was sold for b dollars. But the manager markdown the hardcover books by 42%.

The expression of the markdown using a decimal can be represented below.

Recall the markdown is 42 %. If you want to convert from percentage to a decimal, you have to move the decimal point two places to the left . The percentage sign is removed at this stage and the value is represent in decimal.  Or you can just divide the percentage value by 100.

In our case the percentage value can be solved as 42/100 = 0.42 in decimal or by just simply moving the decimal points two places to the left which is 0.42.

Answer:

C

Step-by-step explanation:

Use sine rule

17/sin130=5/sinB

(5×sin130)÷17=sinB

sinB=0.2253017892

B=sin^-1ans above

=13.4

A=(130+13) subtracted from 180=37°

a/sin37=17/sin130

Answer:

m = 4

Step-by-step explanation:

m−10+6m=10+2m

7m-10=10+2m

Subtract 2m from both sides

5m-10=10

Add 10 to both sides

5m=20

Divide both sides by 5

m=4

Answer:

m=4

Step-by-step explanation:

m − 10 + 6m = 10 + 2m

7m - 10 = 10 + 2m   (subtract 2m from both sides)

7m - 10 - 2m = 10

5m - 10 = 10   (add 10 to both sides)

5m = 10 + 10

5m = 20  (divide both sides by 5)

m = 20/5

m = 4

The answer is 100% B

Step-by-step explanation:

The graph of the polynomial rational function is f ( x ) = x / ( x + 2 ) ( x - 5 )

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the polynomial function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x / ( x + 2 ) ( x - 5 )

The rational function is of the form P ( x ) / Q ( x ) , where Q ( x ) ≠ 0

So , the value of P ( x ) = x

And , the value of Q ( x ) = ( x + 2 ) ( x - 5 )

Therefore , the graph of the rational function is plotted

Hence , the graph of the polynomial is f ( x ) = x / ( x + 2 ) ( x - 5 )

Answer:

smaller r = ( 6.5 , 0)

larger r = ( 21.5 , 0)

vertex = ( 14, -56.25)

Step-by-step explanation:

f(r) = (r -14)² -56.25 square (r-14)

f(r) = r² -28r +196 -56.25 simplify

f(r) =  r² -28r + 139.75

use quadratic formula

x=−b±√(b²−4ac)/ 2a

a = 1, b =-28, c = 139.75

x=−(−28)±√(−28)2−4(1)(139.75)2(1)

x=(28±√225)/2

x=43/2 or x=13/2

or 21.5 and 6.5

This parabola is given in vertex form f (r) = a(r - h)² + k, where (h, k) is the vertex of the parabola so just write the given numbers ( 14, -56.25)

Answer:

bisects, equal, midpoint

Step-by-step explanation:

According to the "Angle Bisector" Theorem, an angle bisector of a triangle divides the opposite side into segments proportional to the lengths of the other two sides of the triangle.

If a ray bisects an angle of a triangle, it divides the opposite side into segments proportional to the lengths of the other two sides. An angle bisector divides an angle into two equal halves. A perpendicular bisector is the line perpendicular to a segment passing through the segment’s midpoint.

Answer:

Length of DE is 25.

Step-by-step explanation:

Right, so this is something called midsegment theorem. ΔDBE is similar (but not congruent) to ΔABC because of the angles they share. Since DE is described as a midsegment, this means BE=EC and BD=DA; so ΔDBE is half the size of ΔABC, meaning its side lengths are also half that of the larger triangle.

Answer:

The second option will cost her less than the first one.

Step-by-step explanation:

In order to solve this problem we will create two functions to represent the cost of the car in function of the miles drove by her.

For the first option we have:

[tex]cost_1(x) = 0.5*x[/tex]

For the second option we have:

[tex]cost_2(x) = 5000 + 0.1*x[/tex]

Since she intends to drive it for 10,000 miles per year for 6 years, then the total mileage she intends to drive her car is 60,000 miles. Applying this to the formula of each car and we have:

[tex]cost_1(60000) = 0.5*60000 = 30000[/tex]

[tex]cost_2(60000) = 5000 + 60000*0.1 = 11000[/tex]

The second option will cost her less than the first one.

Answer

60 apples minus how many she picked (12) or 60-12 divided by 6 baskets. The answer will be 60-12=48. 48 divided by 6 equals 8. The ANSWER IS 8

Step-by-step explanation:

The formula used to calculate how many apples should be included in each gift basket is as follows:

6x = 48

A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.

Jack has 48 apples left after using 12 of the 60 apples he took from the tree to make applesauce.

The leftover apples will be distributed equally among six gift baskets, he said. He puts x apples in each present basket, where x is the number of apples. Then he adds six times as many apples to each of the six gift baskets.

He has to fill the gift baskets with 48 apples, thus we can create an equation:

6x = 48

We may divide both sides of the equation by 6 after finding the value of x:

x = 8

Hence, Jack needs to fill each of the six gift baskets with 8 apples.

The answer to the question what is the value of this expression when a = 7 and b = -4? | 2a | - b/3 it is D.) 6

The value of this expression (|2a| - b)/3 when a = 7 and b = -4 is 6. So, option D is correct.

The absolute value of a number or variable is returned by a modulus function. It is defined as

|x| = x, x > 0

= -x, x < 0

= 0, x = 0

The given expression is (|2a| - b)/3. Here, we have to put a = 7 and b = -4 to get the value.

Now, (|2a| - b)/3 = (|2×7| - (-4))/3 = (|14| + 4)/3 = (14 + 4)/3 [Since 14 is a positive integer]

i.e. (|2a| - b)/3 = 18/3 = 6

Therefore, the value of this expression (|2a| - b)/3 when a = 7 and b = -4 is 6. So, option D is correct.
