Answer:

-5

Step-by-step explanation:

a= -4 than 2 times-4. than be 8.and 4 square is -16. So it be 3+8-16 = -5

Answer:

27

Step-by-step explanation:

[tex]3-2a+a^2\\[/tex]

If a = -4 then just replace a with -4

[tex]3-2(-4)+(-4)^2\\3+8+16\\27[/tex]

Answer:

A is the correct answer

Step-by-step explanation:

Mathematically if we have lengths a, b and c

For a triangle to occur, let us say that the third side is c

then a + b must be greater than or equal to c

Hence c must be equal to (4 + 8) or greater than (4 + 8)

With the options given , A is the correct answer

205ml = 0.205ml

It seems I only get 30 points, ah well.

Answer: 108

Step-by-step explanation:

x = 108

Answer:

2g-10

Step-by-step explanation:

-2(-g+5)  take the -2 and multiply each term in the ()

-2*-g= 2g  Two negatives multiplied turns it into a positive number

-2*5= -10

The answer is 2g-10

Answer:

(-7/2,0) is the x intercept

Step-by-step explanation:

1. y+3 = -6/7x

2.  -3              -3 ....subtract 3 from both sides to isolate the variable y

y= =-6/7x -3 ....is your new equation

You graph it by putting your point on negative three and then counting 6 units down and 7 units right.

For the x intercept you set y to 0 and solve for x

0= -6/7x -3

+3               +3 ...to both sides

3= -6/7x .....divide both sides by -6/7

-7/2=x

put it in as a coordinate

Answer:

what's that 120 which angle is that

Step-by-step explanation:

Triangle AGB has Angle AGB = 120° and AG = GB. (given)

Since it is isosceles, x = (180° - 120°)/2 = 30°.

then just solve for b

sorry if this looks weird i havent written inequalities since 8th grade

Answer:

0* 1/9*9=0

Step-by-step explanation:

The zero property of multiplication states that any non-zero number multiplied by zero will equal zero.

it can't be the first one, since there's no zero in it, and the answer isn't zero

it can't be the second one since there's no multiplication illustrated.

The third one is an option, since there is a zero and it's being multiplied by two non-zero numbers, and the answer is 0

the fourth one isn't an option since there's no multiplication

the fifth one isn't an option since there is no 0's there.

hope this helps!

Answer:

15

Step-by-step explanation:

AB + BC = AC

2x + 1 + x = 22

3x + 1    = 22

        3x = 22 -1

        3x = 21

         x = 21/3

   x = 7

AB = 2*7 +1

      = 14 + 1

      = 15

Answer:

The correct option is;

A. Car B was 10 miles east of car A

Step-by-step explanation:

The given parameters are;

The speed of car A = 45 miles per hour

The direction of car A = East

The distance of car B from Johnstown after 2 hours = 100 miles east

The direction of Car B = East

The distance of car B from Johnstown is given on the graph

Therefore, the initial distance of car A from Johnstown when car A began driving is given as follows;

The initial distance, east, of car A from Johnstown = 100 - 2 × 45 = 10

∴ The initial distance, east, of car A from Johnstown = 10 miles

From the graph, the initial distance, east, of car B from Johnstown = 20 miles

Therefore, car B was 10 miles east of car A

Answer:

Car B was 10 miles east of car A

Step-by-step explanation:

Answer:

Step-by-step explanation:

Part A

for f(x) slope between points (-1,-6) and (1,0)

m= y2-y1/x2-x1 = -6-0/-1-1 = -6/-2= 3

for g(x) slope m=4 because we compare to equation y=mx+b the given equation g(x)=4x-5

The slope of f(x) is 3 and the slope g(x) is 4 so the line of g(x) is steeper

part B

The y intercept for g(x) is  (0, -5)

The equation of f(x) can be found

y-y1 =m(x-x1) take any point for example point (1,0)

y-1 =3(x-0)

y=3x+1 so the y-intercept is at (0,1)

The y-intercept for f(x) is greater at y=1 then the one of g(x) at y=-5

The ladder would be 12.4 feet hope that helps

Answer:659

Step-by-step explanation:

Answer:

33:79

Step-by-step explanation:

We are told that a factory is going to hire 33 new employees.

and the total applicants is 79

In this problem, we want to represent the situation as a ratio of new hires to applicants

Since the question says  new hires to applicants

Hence, the ratio will be

33 to 79

or

33/79, we can simplify this as

33:79

Answer:

[tex]y=-4x+1[/tex]

Step-by-step explanation:

To get this, use the following steps:

1) Knowing that line q is perpendicular to the line p, the slope of line q must be the negative reciprocal of the slope of line p. Thus the slope is [tex]-(\frac{1}{4})^{-1} = -4[/tex]

2) To find the equation, plug in the point given:

   [tex]5 = -4(-1) + b[/tex]

   [tex]b = 1[/tex]

3) The equation of line q is thus:

   [tex]y= -4x+1[/tex]

Answer:

Yes

Step-by-step explanation:

Yes, that is exactly what Sarah did wrong. Apparently, she tried to divide both the numerator and denominator in this problem by 2 (half) but divided the numerator incorrectly. 26 divided by 2 would equal 13 but Sarah mistakenly calculated it as 14 which would give her a totally different value when divided by the new denominator. If were to have divided correctly it would give her [tex]\frac{13}{4}[/tex] which is the same as [tex]\frac{26}{8}[/tex]

(If one square on the graph = one centimeter)

b = 10cm

h = 10cm

Area

[tex] = \frac{1}{2} \times b \times \: h[/tex]

[tex] = \frac{1}{2 } \times 10 \times 10[/tex]

[tex] = \frac{1}{2} \times 100[/tex]

[tex] = 50 {cm}^{2} [/tex]
