Nafeesa graphed a line with a slope of 5 and a y-intercept of (0,-2) A. Find an equation for her line.
B. Find the value of x when y=0
Answers
In this question , it is given that slope of 5 and a y-intercept of (0,-2) .
Now we have to check out the equation of the line that we are gonna use here.
Here we use the slope intercept form, which is
where m is the slope , which is 5 here and y intercept is b , which is -2 here.
Substituting these values in the equation, we will get
Part b .
Now we have to substitute 0 for y, and find the value of x, that is

Answers
length = w + 8 and width = w and A = 105
A = W* L
105 =w(w + 8)
105 = w² + 8w
0 = w² + 8w - 105
0 = (w + 15)(w -7)
0 = w + 15 or 0 = w -7
w = -15 or w = 7
width cant be negative, so
w = 7 and L = 7 +8
w = 7 and L = 15
7 * 15 = 105 check
length=x+8
according to the question
area of the pool = l*b
105=x*x+8
if u solve this equation further u will get the answer

Answer:
-6m-12
Step-by-step explanation:
-(2m-7)-(3+4(m+4)) =
-2m+7-(3+4m+16)=
-2m+7-(19+4m)
-2m+7-19-4m
-6m-12
OR:
-m-2 ( if you divide by 6 as a common factor)

Answer: Breadth = 11 ; Length = 8
Step-by-step explanation:
Let the width of the rectangle be 'x'
Length of the rectangle = x - 3
Perimeter of the rectangle = 38
Perimeter of rectangle formula = 2 ( length + breadth )
Substitute:
2 ( x + x-3 ) = 38
2 ( 2x - 3 ) = 38
2x - 3 = 19
2x = 19 + 3
2x = 22
x = 11
Therefore, the breadth = 11
Length = x-3 = 11 - 3 = 8
To check, find the perimeter:
2( 11 + 8)
= 2 ( 19 )
= 38.
We get the same perimeter so the answer is correct.
Answer:
length =8
Step-by-step explanation:
x= width
x-3(3 inches less than the width)
x+x-3+x+x-3=38
4x-6=33. add 6 on both sides
4x=44 divide by 4
x=11. plug 11 in for x because 11 is the width. in the equation x-3. (x=width) 11-3= 8. The length is 8.

Since there is sign +, we expect it to be the sum. Among all choices, only the last one includes summation, and that is sum of cubes.
Let's check it out.
Sum of cubes can be expresses as:
a³ + b³ = (a + b)(a² - ab + b²)
Let's see what are cube roots of 125 and 8:
∛125 = ∛5·5·5 = ∛5³ = 5 ⇒ a = 5
∛8 = ∛2·2·2 = ∛2³ = 2 ⇒ b = 2
Now, let's implement that in the equation of sum of cubes:
5³ + 2³ = (5 + 2)(5² - 5·2 + 2²)
125 + 8 = 7 · (25 - 10 + 4)
133 = 7 · 19
133 = 133
Therefore, sum of cubes is the right answer.
