-9-7+5n

Step-by-step explanation:

Answer:

-16+5n

Step-by-step explanation:

combine -9 minus 7 which is -16 and 8n - 3n which is 5n

Answer:

See below

Step-by-step explanation:

f(x) = -2x + 2

Put x = 1

f(1) = -2(1) + 2

f(1) = -2 + 2

f(1) = 0

Put x = 0

f(0) = -2(0) + 2

f(0) = 2

Put x = -1

f(-1) = -2(-1) + 2

f(-1) = +2 + 2

f(-1) = 4

Put x = 2

f(2) = -2(2) + 2

f(2) = -4 + 2

f(2) = -2

Answer:  A verticle line does not have a slope.

Step-by-step explanation:  Slope is the rate of change of y for each change in x.  y = 2x is a line with slope of 2.  Each time x is incremented by 1, y will increase by twice (2x) that amount.  There is no slope to a verticle line, unless you want to call it infinite.  The value of y is not defined by x.

Answer:

multiply -1.25 x 12

Sense a negative and a positive will always be negative when dealing with multiplication you'll get -15

now -15 +651= 636

Step-by-step explanation:

The parts of the graph where it is going 'up' are where it is increasing.

This is between x = - 4 to x = 0 and between x = 5 to infinity

Expressing in interval form the graph is increasing for

(- 4, 0 ) and (5, ∞ )

Answer:

x > -3.4

Step-by-step explanation:

1 < (x + 5.5) / 2

first multiply each side by 2

2 < x + 5.5

Then subtract 5.5 from each side

-3.4 < x

x has to be on the left so you switch the hole equation around to get

x > -3.4

Answer:

[tex]4 \times {( - 3)}^{3} + 10 = 4 \times ( - 27) + 10 = - 108 + 10 = - 98[/tex]

Answer:

Below.

Step-by-step explanation:

The slope = difference of y values/ difference of x values

13. Slope = (-5-5)/(-3-2)

= -10/-5

= 2.

14. Slope = (-8-8)/(7-9)

= -16/-2

= 8.

Answer:

Out of State = 54

Step-by-step explanation:

Out of State

2/9 = x/243

= 54

Answer:

54

Step-by-step explanation:

7 in-state to 2 out-of-state

The sum of 7 and 2 is 9.

For every 9 students, 2 are out of state.

This is the proportion:

2 out-of-state is to 9 total as x out-of-state is to 243 total

2/9 = x/243

9x = 2 * 243

x = 54

Answer: 54

Answer:

x's value is 12 while y's value is 6.

[tex]\cfrac{7}{6}[/tex]

Step-by-step explanation:

[tex]\cfrac{7}{8} \div \cfrac{3}{4}[/tex]

Divide 7/8 by 3/4 by multiplying 7/8 by the reciprocal of 3/4:

[tex]\cfrac{7}{8}\times[/tex] [tex]\dbinom{4}{3}[/tex]

Now, multiply 7/8 times 4/3 by multiplying numerator times numerator and denominator times denominator:

[tex]\cfrac{7\times 4}{8\times 3}[/tex]

Do multiplication in fraction: [tex]\cfrac{7\times 4}{8\times 3}[/tex]

Reduce fraction [tex]\frac{28}{24}[/tex] to lowest terms by extracting and canceling 4 out:

Answer:

3×10'-2 is larger

Step-by-step explanation:

2×10'-3=0.002

3×10'-2=0.03

Answer:

3x10^-2 is larger

Step-by-step explanation:

2x10^-3 = 0.002

beause 10^-3 = decimal place three place to the left

3x10^-2 = 0.03

beause 10^-2 = decimal place two place to the left

Answer:

2133120

Step-by-step explanation:

using 6 given digits, lets create a 4 digit number:

to choose the first number, you have 6 options. to choose the second number we have 5 options left. for the third number we have 4 options left. and for the fourth number, we have 3 options left.

6*5*4*3 = 360

with no repeats, 360 numbers can be formed.

this means that each number will occur 60 times each (360/6 digits)

so to find the sum:

60*(2+4+5+6+7+8) = 1920

but, we have one more thing:

In the thousands place, our sum of digits is multiplied by 1000; in the 100’s place, by 100; in the ten’s place, by 10; and in the one’s place, by 1. so:

1920(1000+100+10+1) = 1920*1111 = 2133120

Answer:

  b) x < -4

Step-by-step explanation:

Eliminate parentheses and you have ...

  4x +4 > 16 +7x

  -12 > 3x . . . . . . . . subtract 4x+16

  -4 > x . . . . . . . . divide by 3

The number line will have an open circle at -4 and be shaded to the left. The pictures are a bit fuzzy, but we think choice B has that description.

Answer:

45

Step-by-step explanation:

Because GH=GI

so H=I=45

Answer:

[tex]c = 45[/tex]

Step-by-step explanation:

[tex]Isosceles \: Right \: Tringle[/tex]

[tex]∠c=∠GIH[/tex]

[tex]180-90=90[/tex]

[tex]c = \frac{90}{2} [/tex]

[tex]c = 45[/tex]

Answer:

43°

(4x + 19)° = (6x + 7)° [vertically opposite angles are equal]

4x+19 = 6x+7

4x + 19 -7 = 6x

4x +12 = 6x

12 = 6x - 4x

12 = 2x

2x = 12

x = 12/2

x = 6

Now replace the x with 6

(4x+19)°

= (4×6+19)°

= (24+19)°

= 43°

(6x+7)°

= (6×6+7)°

= (36+7)°

= 43°

The measure of the angles is 43 degrees

Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Given the system of equation expressed as:

3x + y = 3

x - 2y = 4

Solve simultaneosly;

3x + y = 3 ............. 1 * 1

x - 2y = 4 ...............2 * 3

_________________________

3x + y = 3

3x - 6y = 12

Subtract

y-(6y) = 3 - 12

7y = -9

y = -9/7

Substitute y = -9/7 into the equation to get x

x - 2y = 4

x - 2(-9/7) = 4

x + 18/7 = 4

x = 4 -  18/7

x = 3/7

Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
