Answer:
The correct answer is B
Step-by-step explanation:
Which of the following graphs represents the solution set for y< -2x – 4?
Given:
The inequality is [tex]y<-2x-4[/tex].
To find:
The graph of the given inequality.
Solution:
The inequality is
[tex]y<-2x-4[/tex]
The related equation is
[tex]y=-2x-4[/tex]
For x=0,
[tex]y=-2(0)-4[/tex]
[tex]y=0-4[/tex]
[tex]y=-4[/tex]
For y=0,
[tex]0=-2x-4[/tex]
[tex]4=-2x[/tex]
[tex]\dfrac{4}{-2}=x[/tex]
[tex]-2=x[/tex]
So, the related line passes through two points (0,-4) and (-2,0).
Sign of inequality is <, so the related line is a dotted line and shaded region is below the related line.
Therefore, the correct option is B.

10. One number is twenty more than eight times another number. The sum of the
numbers is eleven. Find the two numbers.
Answer:
the two numbers are 12 and -1.
Step-by-step explanation:
Let the large number be represented by x and the smaller number by y.
So that;
x = 8y + 20 .................. 1
x + y = 11 ................... 2
From equation 2,
x = 11 - y .......... 3
Substitute equation 3 into equation 1 to have,
11 - y = 8y + 20
11 - 20 = 8y + y
-9 = 9y
divide through by 9 to have,
y = -1
Substitute the value of y in equation 3,
x = 11 - (-1)
= 11 + 1
= 12
x = 12
x = 12, y = -1
The two numbers are 12 and -1.

What is the sum (2/5x + 5/8) + (1/5x - 1/4)? a. 3/5 x + 1/8 b. 3/5 x + 3/8 c. 3/5x + 5/8 d. 3/5x + 7/8
Answer:
3/5x + 3/8
Step-by-step explanation:
2/5x + 5/8 + 1/5x - 1/4
1. Combine like terms so now u have
3/5x + 3/8
In case you want to know how I got 3/8
You want a common denominator so
from 5/8 + 1/4, make both denominator 8
so 1 *2/ 4* 2
so now you converted the 1/4 to 2/8
So then 5/8 - 2/8 gives u 3/8 and that's how i got 3/8
Hope this helped!

3/5x + 3/8

Answer:
83 in.^2
Step-by-step explanation:
The entire polygon consists of a rectangle with length 8 in. and width 5 in., a triangle with base 8 in. and height 7 in., and another triangle with base 5 in. and height 6 in.
The total are is the sum of the area of the rectangle and the two triangles.
area = area of rectangle + area of first triangle + area of second triangle
area = LW + bh/2 (for the first triangle) + bh/2 (for the second triangle)
area = 8 in. * 5 in. + 8 in. * 7 in. / 2 + 5 in. * 6 in. / 2
area = 40 in.^2 + 28 in.^2 + 15 in.^2
area = 83 in.^2

find (4.54×10^8)-(3.98×10^8)
Answer:
[tex]5.6 *10^7[/tex]
Step-by-step explanation:
Given
[tex](4.54*10^8)-(3.98*10^8)[/tex]
Required
Solve
[tex](4.54*10^8)-(3.98*10^8)[/tex]
Apply distributive law of algebra
[tex](4.54 - 3.98) *10^8[/tex]
Evaluate the expression in bracket
[tex](0.56) *10^8[/tex]
Remove bracket
[tex]0.56 *10^8[/tex]
When a number is in standard form: [tex]a * 10^n[/tex]
The value of a must be: [tex]1 \le a \le 10[/tex]
So, the expression becomes:
[tex]5.6 *10^{-1}*10^8[/tex]
Apply law of indices
[tex]5.6 *10^{-1+8}[/tex]
[tex]5.6 *10^7[/tex]

Write 3/5 as a division
Answer:
3/5 as a division is 0.6
Step-by-step explanation:
To write a fraction as a division, we basically divide the values, since the fraction represents a division.
In this question:
We want 3 divided by 5.
3 is less than 5, so we can multiply 3 by 10(getting 30), and adding a 0 to the quotient.
So now 0.(30/5) = 0.6, which means that 3/5 as a division is 0.6.
Find the height of an equilateral triangle with side length 8.
Answer:
U need to just do
[tex] \sqrt{3 \div 4} a {}^{2} [/tex]
Answer:
4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
The segment from a vertex to the side opposite is a perpendicular bisector.
The equilateral Δ is divided into 2 right triangles with legs 8 and 4
let height be h, then using Pythagoras' identity
h² = 4² + 8² = 16 + 64 = 80 ( take the square root of both sides )
h = [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex] ← exact value
