Answer:

B. 3(x+2) can be rewritten as 3x+6 using the distributive property.

Step-by-step explanation:

When you distribute 3 into x and 2 you get the equation 3x+6 (3x and 3(2)) which makes the expressions equivalent.

Step-by-step explanation:

Domain is the range of x-values for the function to be defined.

Domain of f(x) = [2,9]

Domain of g(x) = [2,9]

Slope = -1/2

Y intercept = -9/2

=====================================================

Work Shown:

2x + 4y = -18

2(x+2y) = -18 .... factor out 2

x+2y = -18/2 .... divide both sides by 2

x+2y = -9

2y = -9-x .... subtract x from both sides

2y = -x-9

y = (-x-9)/2 ... divide both sides by 2

y = (-x/2) - (9/2) ... break up the fraction

y = (-1/2)x - 9/2

The last equation is in slope intercept form y = mx+b with m = -1/2 as the slope and b = -9/2 as the y intercept.

Answer:

Step-by-step explanation:

2x + 4y = -18

2(x+2y) = -18 .... factor out 2

x+2y = -18/2 .... divide both sides by 2

x+2y = -9

2y = -9-x .... subtract x from both sides

2y = -x-9

y = (-x-9)/2 ... divide both sides by 2

y = (-x/2) - (9/2) ... break up the fraction

y = (-1/2)x - 9/2

The last equation is in slope intercept form y = mx+b with m = -1/2 as the slope and b = -9/2 as the y intercept.

Cesar has 32 boxes of pasta and 48 jars of sauce that he will be putting into bags for a food drive. He wants each bag to have the same amount of pasta and sauce and wants to use all of the items. Use the drop-down menus to complete the statements below about the number of bags Cesar can make.

What is the greatest number of bags Cesar can make and Each bag would have _____ pasta and _____ jars of sauce

Answer:

The greatest number of bags Cesar can make is 16 bags.

Each bag would have 2 pasta and 3 of jars of sauce

Step-by-step explanation:

We solve the above question using Greatest Common Factor method

The factors of 32 are: 1, 2, 4, 8, 16, 32

The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Then the greatest common factor is 16.

Hence, the greatest number of bags Cesar can make is 16 bags.

For Pasta, We have 32 pasta

Each bag would have: 32/16

= 2 pasta

For Jars of sauce, we have 48 jars of sauce.= 48/16

= 3 jars of sauce

Answer:

Right triangle

Step-by-step explanation:

90 degrees means that it's a right angle

Answer:

Acute triangle

Step-by-step explanation:

Answer:

-328/34

Step-by-step explanation:

Here,

Perimeter of rectangle = 6(12x+5)

Perimeter of equilateral triangle = 4(x-2)

Since they are equal, 6(12x+5) = 4(x-2)

or, 72x + 30 = 4x - 8

or, 68x = -38

or, x= -38/68 or -19/34

Now,

Area of triangle ( or rectangle whichever you prefer)

= 4* -19/34 - 8

= -76/34 - 8

= - 328/34

Answer:

I think it is the last one .

Step-by-step explanation:

Answer:

acute

Step-by-step explanation:

sorry if im wrong how I did it is on a paper or create a picture in your mind have a good night if you have a question please ask away in the comments

This triangle is obtuse.

Triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.

Let a = 6 ,b = 11 & c = 14 be the sides of a traingle, c being longest of three

If a²+b²=c² it is right angled,

If a²+b²>c² it is acute,

If a²+b²<c² it is abtuse,

Substitue the values of a, b and c,

a²+b²= 6²+11² = 157

c² = 14² = 196

Since a²+b²<c²

Hence, this triangle is obtuse.

This is because math.

Answer:

D. No; the graph fails the vertical line test

The correct option is D.  No,  the graph fails the vertical line test.

The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function. It is done by visually examining the number of intersections of the curve with vertical lines.

In the given graph, the graph of a function intersects the y axis twice.

Any vertical line in the x y plane must intersect the graph of a function at most once.

Thus, the correct option is D.

Answer: Trial B is [tex]1\dfrac{3}{4}[/tex] miles longer then Trail A.

Step-by-step explanation:

Length of Trail A = [tex]6\dfrac34[/tex] miles

= [tex]\dfrac{24+3}{4}[/tex]  miles = [tex]\dfrac{27}{4}[/tex] miles.

Length of Trail B = [tex]8\dfrac12[/tex] miles

= [tex]\dfrac{16+1}{2}[/tex] miles = [tex]\dfrac{17}{2}[/tex] miles.

Trial B is longer then Trail A by [tex]\dfrac{17}{2}-\dfrac{27}{4}[/tex] miles

[tex]=\dfrac{17\times2}{2\times2}-\dfrac{27}{4}[/tex] miles

[tex]=\dfrac{34}{4}-\dfrac{27}{4}[/tex] miles

[tex]=\dfrac{7}{4}[/tex] miles

[tex]=1\dfrac{3}{4}[/tex] miles

Hence, Trial B is [tex]1\dfrac{3}{4}[/tex] miles longer then Trail A.

let the marks obtained in maths be x

total marks obtained by susan=142+x

then

A/Q

60%of 450 =(142+x)

270=142+x

x=270-142

x=128

hence marks obtained in maths=128

OR

Max marks 120+150+180=450

60% of 450 is 270
