Find the solution set for the given inequality. -7x + 3 > 45 A) Show your work to solve this inequality (B) Graph the solutio

scoundrel [369]

Answer:

See explanation

Step-by-step explanation:

Given the inequality $-7x+3>45$

A) Add -3 to both sides of inequality:

$-7x+3-3>45-3\\ \\-7x>42$

Divide by -7 (remember, dividing the inequality by negative number changes the sign of inequality):

$x$

B) Plot open circle at -6 on the number line and shade all values of x which go to the left from -6 (see attached diagram).

The product of three consecutive integers is 3360. What is the sum of the three integers?

Tom [10]

Step-by-step explanation:

let the integer be x .

three consecutive integers : x, x+1, x+2.

according to the problem,.

Let the first of the 3 consecutive numbers be X.

Therefore the second number is (X + 1)

The third number is therefore (X + 2)

The product of the 3 consecutive numbers is:

( X )( X + 1 )( X + 2 ) = 3360 Equation( 1 )

Expanding Equation ( 1 ) gives

X³ + 3X² + 2X - 3360 = 0 Equation (2)

Solve Equation (2 ) which gives the following values for X

X1 = 14

X2 = - 8.5 + i (12.951834)

X3 = - 8.5 - i (12.951834).

the numbers are 14,15,16.

sum is 14+15+16 = 45.

hope this helps you.

I will mark branlest if you are right

schepotkina [342]

Answer:

1) y=(-1/4)x+(11/4)

2) y=(4)x-33

3) y=(2/3)x-11/3

4) y=(5)x-2

5) y=(3)x-7

6) y=(-1/4)x+(6)

Step-by-step explanation:

1) y=mx+b 3=(-1/4)(-1)+b b= 11/4

2) y=mx+b -5=(4)(7)+b b= -33

3) y=mx+b -5=(2/3)(-2)+b b= -11/3

4) y=mx+b 3=(5)(1)+b b= -2

5) y=mx+b -1=(-3)(-2)+b b= -7

6) y=mx+b 7=(1/4)(4)+b b= 6

Find the area of the triangle. Figure is not drawn to scale. Show your work. (Image attached)

Zolol [24]

Answer: $13.8cm^2$

Step-by-step explanation:

The area of a triangle can be calculated with the formula:

$A_{(triangle)}=\frac{b*h}{2}$

The base of the triangle is "b" and the height of the triangle is "h",

In the figure you can observe that the base and the height of the triangle are:

$b=6.9cm\\h=4cm$

Knowing these values, you can substitute them into $A_{(triangle)}=\frac{b*h}{2}$ .

Therefore, the area of the triangle is:

$A_{(triangle)}=\frac{(6.9cm)(4cm)}{2}$

$A_{(triangle)}=13.8cm^2$
