Answer:

$8+3x^2+7x+4$

Step-by-step explanation:

The first expression is

$7+3x^2+7x+3$

The sum of the constants is 7+3=10

The sum of the coefficients is 3+7=10

The second expression is;

$7+4x^2+4x+1$

The sum of the constants is 7+1=8

The sum of the coefficients is 4+4=8

The third expression is;

$8+4x^2+8x+2$

The sum of the constants is 8+2=10

The sum of the coefficients is 4+8=12

The fourth expression is;

$8+3x^2+7x+4$

The sum of the constants is 8+4=12

The sum of the coefficients is 3+7=10

Hence the correct choice is the expression in which the sum of the constants greater than the sum of the coefficients

A line passes through $A(1,1)$ and $B(100,1000)$. How many other points with integer coordinates are on the line and strictly be

jonny [76]

Answer:

Step-by-step explanation:

Integers are whole numbers or opposite of whole numbers.

The slope is 1.

How?

Change of y is 100-1=99.

Change of x is 100-1=99.

The slope is 99/99=1 or 1/1.

So if we start at (1,1) and we rise 1 and run 1 right, we get (2,2).

If we do that again from (2,2) we get (3,3).

Following the pattern of going up 1 and right from each new location discovered we get all the of these points:

Start (1,1)

(2,2)

(3,3)

(4,4)

(5,5)

(6,6)

....

(96,96)

(97,97)

(98,98)

(99,99)

end (100,100)

So we just need to count all the numbers from 2 to 99.

99-2+1

97+1

Solve for g gg. Give an exact answer. 10 ( 0.4 + 0.5 g ) = 4 g 10(0.4+0.5g)=4g10, left parenthesis, 0, point, 4, plus, 0, point,

kirill115 [55]

Answer:

the value of g is -4

Step-by-step explanation:

$10 ( 0.4 + 0.5 g ) = 4 g$

Our aim is to solve for g

multiply 10 inside the parenthesis

$4+5g = 4g$

Now combine like terms

Subtract 5g from both sides

$4+5g-5g= 4g-5g$

$4=-g$

Divide both sides by -1

$g=-4$

Find the value of two numbers if their sum is 12 and their difference is 4

IrinaK [193]

X + y = 12
x - y = 4
-----------------add
2x = 16
x = 8

x - y = 4
8 - y = 4
y = 4

answer
two numbers: 8 and 4

doule check
sum = 8 + 4 = 12
difference = 8 - 4 = 4
