What point is a solution for the linear inequality below?

A. (4, 3)
B.(-2, 4)
C.(-4,1)
D.(1, -2)

Answer:

she made $68 last week.

Answer:

$68

Step-by-step explanation:

you need to divide 8 by 2 which is 4

then multiply 4 by 17 which equals 68.

Answer:

direct

Step-by-step explanation:

The standard form of an equation representing direct variation is

y = kx ← k is the constant of variation

The standard form of an equation representing inverse variation is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]

y>= -6.5+9x

Answer:

Step-by-step explanation:

Answer:

(a) TRUE

(b) TRUE

(c)  FALSE

(d) TRUE

Step-by-step explanation:

" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".

(a) TRUE

Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0

(b) TRUE

this could be seen clearly from the number line.

(c) FALSE

this statement is false since we can take example of zero.

the opposite of zero is 0 but 0×0≠1.

(d) TRUE

since 0-0=0.Step-by-step explanation:

Answer:X=3

y= -4

Step-by-step explanation:

If we're solving for x or y, then the intercept we're not solving for is equal to zero. Solving for y means x=0, solving for x means y=0.

so solving for x, 4x=12--> x=3, since y=0 in this scenario.

Solving for y, x=0, so -3y=12--> y=(-4)

9514 1404 393

Answer:

  see below for a table

Step-by-step explanation:

You can easily identify intercept points by solving for one variable when the other is zero.

x-intercept (y=0)

  4x = 12

  x = 12/4 = 3

y-intercept (x=0)

  -3y = 12

  y = 12/-3 = -4

So, the coordinate pairs of these points are ...

  (3, 0) and (0, -4)

__

If you solve for y, you get ...

  -3y = 12 -4x

  y = (4/3)x -4 . . . . . divide by -3

This suggests that x being a multiple of 3 will be useful for finding integer values of y.

We already have points for x=0 and x=3. We can add points for x=6 and x=-3.

  y = 4/3(6) -4 = 4

  y = 4/3(-3) -4 = -8

So, the additional points are ...

  (6, 4) and (-3, -8)

The solution is where the two lines cross each other:

(-1,3) and (2,6)

The answer is B.

Answer:

6x+8y = 3

Step-by-step explanation:

we have 3x + 4y = 7

4y = -3x + 7

y = -3/4 x + 7/4

so slope is -3/4

2 parallel lines always have same slope

so the slope of our new line is -3/4

so y = -3/4 x + C

for c,

we have (x,y) = (-2/3,7/8)

7/8 = -3/4 * -2/3 + C

C = 3/8

so equation is

y = -3/4 x + 3/8

simplyfyig,

8y = -6x + 3

or, 6x+8y = 3

5. 3050ft³ (rounded to 3 s.f.)

6. 4190ft³(rounded to 3 s.f.)

7. 4600ft³(rounded to 3 s.f.)

Formulas (For easier reference):

Volume of a cone: pi×r²×[tex]\frac{h}{3}[/tex]

Volume of cylinder: pi×r²×h

Volume of a sphere: [tex]\frac{4}{3}[/tex]×pi×r³

Volume of a hemisphere: [tex]\frac{2}{3}[/tex]×pi×r³

Step-by-step explanation:

You can just apply the formulas to the question:

5. Volume of cone = pi×9²×[tex]\frac{(16-10)}{3}[/tex]

                               = 162pi

  Volume of cylinder = pi×9²×10

                                   = 810pi

Volume of figure = 162pi+810pi

                            = 972pi

                            = 3050ft³ (rounded to 3 s.f.)

6. Volume of sphere = [tex]\frac{4}{3}[/tex]×pi×10³

                                   = 1333[tex]\frac{1}{3}[/tex]pi

                                   = 4190ft³(rounded to 3 s.f.)

7. Volume of hemisphere = [tex]\frac{2}{3}[/tex]×pi×(26÷2)³

                                          = 1464[tex]\frac{2}{3}[/tex]pi

                                          = 4600ft³(rounded to 3 s.f.)

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

If we multiply any negative number in this case -3 times a POSITIVE we will always get a negative. So the positive we can put as x and multiply -3 times x = -3x.

Answer:

10 : 12 is equivalent to 5 : 6 and 20 : 24.

Step-by-step explanation:

You can divide and multiply the ratio by 2 to get an equivalent ratio.

The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24 Therefore, option (C) will be correct.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given ratio, 10:12.

Divide numerator and denominator by 2

(10/2):(12/2) = 5:6.

Multiply the numerator and denominator by 2

(10×2);(12×2) = 20:24

Hence "The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24".

Answer:

26x47

Step-by-step explanation:

To calculate the length of the rectangle we would do 2(2x - 5) + 2(x) = 146

We simplify and get 6x - 10 = 146,

then divide both side by 6 and plus 10 both sides,

we will get

x = 26

Now we've found one of the length,

to find the other side we do 26 * 2 = 52, and subtract 52 from 146,

which would get 94, then we divide it by 2

94/2 = 47

The dimensions is 26x47

The actual answer is 3.25

Step-by-step explanation:

I just took the test

the maximum number of hours that the repair person can work is 3.5 hours

Given :

Gloria doesn’t want to spend more than $100.

A service call will cost $35 and the labor will be an additional $20 per hour

Let 'h' be the maximum number of hours the repair can take.

Lets find out the total cost for 'h' hours

35+ additional 20 per hour

[tex]35+20h[/tex]

The total cost should not exceed 100

[tex]35+20h \leq 100\\20h \leq 100-35\\20h\leq 65\\Divide \; by \; 20\\h\leq 3.5[/tex]

So , the maximum number of hours that the repair person can work is 3.5 hours
