Find two consecutive positive integers such that the square of the
smaller integer is nineteen more than five times the larger integer.
Answer:
8 and 9
Step-by-step explanation:
let 'n' = smaller positive integer
let 'n+1' = larger
n² = 5(n+1)+19
n² = 5n + 5 + 19
n² = 5n + 24
n² - 5n - 24 = 0
(n-8)(n+3) = 0
n = 8 [this is the smaller positive integer]
n+1 = 9 [this is the larger positive integer]
n = -3 [this value can be discounted because it is not positive]
PLEASE HELP ASAP! What system of linear inequalities is shown in the graph?
Step-by-step explanation:
x+2y ≥ 4 => y ≥ -½x +4
-2x + y > -3 => y > 2x - 3
Answer:
Work out the equations of the lines first.
The solid line
It has a slope of m = (1 - 2)/2 = -1/2 and the y-intercept of 2The line is:
y = -1/2x + 2The dotted line
It has a slope of m = (-1 + 3) / 1 = 2/1 = 2 and the y-intercept of -3The line is:
y = 2x - 3The intercession zone is above of both of the lines, so the inequalities are:

Answer:
ans: 80 °
Step-by-step explanation:
given two triangle are isosceles triangle so,
triangle having angle a;
a + 2d = 180
d = 54° ( since a= 72°)
d is vertically opposite to angle of triangle containing x,
similar reason for b ,
hence
x+ d + b = 180
x = 180 - 54 - 46
= 80°
Morgan borrowed $0.35 from her mother every time she went to the gas station to buy some chips. Over the summer Morgan went to the grocery store with her mother 9 times. Write an expression using rational numbers to show how much money Morgan borrowed from her mother. Then determine how much Morgan owes her mother.

Does anyone know this? Options: 5,6,or 10
Answer:
x = 6
Step-by-step explanation:
a • b = c • d where a and b are the segments lengths on one chord and c and d are the segments lengths on the other chord
2*x = 3*4
2x = 12
Divide by 2
2x/2 = 12/2
x = 6
Which sequence is generated by the function f(n + 1) = f(n) – 2 for f(1) = 10?
Answer: The sequence generated is 10, 8, 6, 4, 2, ...
This sequence is arithmetic with starting term 10 and common difference -2. This means we add -2 to each term to get the next one (same as subtracting 2 from each term). This common difference is directly connected to the -2 from the recursive rule f(n+1) = f(n)-2
Whatever the nth term f(n) is, we subtract off 2 to get f(n)-2 to get the f(n+1) term, which is right after the nth term.
Answer:
Step-by-step explanation:
f(1)=10
n=1
f(1+1)=f(1)-2
f(2)=10-2=8
n=2
f(2+1)=f(2)-2
f(3)=8-2=6
n=3
f(3+1)=f(3)-2
f(4)=6-2=4
so sequence is 10,8,6,4,...

A diver was at 58m below sea level.The diver swam up 4m every 12 seconds. Where is the location of the diver after 2 minutes?
Answer:
18 metres below sea level.
Step-by-step explanation:
Since the diver swims up 4 metres every 12 seconds, that means the diver swims up 4 * (60/12) metres = 20 metres every minute. Therefore, he will have swum up 20 * 2 = 40 metres after 2 minutes. Factoring in the diver's original position, -58m, we can calculate his position to be -58 + 40 metres = -18 metres, meaning 18 metres below sea level.
Hope this helped!

What is the area of the top of the installed countertop, to the nearest square foot?
Answer:
19 square foot
Step-by-step explanation:
A countertop for a kitchen is modeled with the dimensions shown below. An 18-inch by 21 inch rectangle will be removed for the sink. What is the area of the top of the installed countertop to the nearest square foot.
Convert from inches to feet
18 inches
1 inch = 0.0833 feet
18 inch = x
Cross Mulitiply
x = 18 × 0.0833 feet
x = 1.5 feet
21 inches
1 inch = 0.0833 feet
21 inch = x
Cross Mulitiply
x = 21 × 0.0833 feet
x = 1.75 feet
Area 1 = 2 ft × 8 ft = 16 ft²
Area 2 = 2 ft × 3 ft = 6 ft²
Area of a sink = Length × Width
= 1.5 ft × 1.75 ft
= 2.625 square feet
Area 1 - Area of sink
= 16 ft² - 2.625 ft²
= 13.375 ft²
Area of the top installed part =
Area 2 + 13.375 ft²
= 6 ft² + 13.375 ft²
= 19.375 ft²
Approximately ≈ 19 ft²

Line segment EG is partitioned by point F in the ratio 1:3. Point E is at E (0, 4), and point F is at (1, 3). What are the coordinates of point G? (−1, 5) (2, 2) (3, 1) (4, 0)
Answer:
(4,0)
Step-by-step explanation:
Line segment EG is partitioned by point F in the ratio 1:3.
This means that:
[tex]F - E = \frac{1}{4}(G - E)[/tex]
We use this equation to find both the x-coordinate and the y-coordinate of point G.
x-coordinate:
x-coordinate of E: 0
x-coordinate of F: 1
x-coordinate of G: x
Then
[tex]F - E = \frac{1}{4}(G - E)[/tex]
[tex]1 - 0 = \frac{1}{4}(x - 0)[/tex]
[tex]1 = \frac{x}{4}[/tex]
[tex]x = 4[/tex]
y-coordinate:
y-coordinate of E: 4
y-coordinate of F: 3
y-coordinate of G: y
Then
[tex]F - E = \frac{1}{4}(G - E)[/tex]
[tex]3 - 4 = \frac{1}{4}(y - 4)[/tex]
[tex]-1 = \frac{y-4}{4}[/tex]
[tex]y - 4 = -4[/tex]
[tex]y = 0[/tex]
What are the coordinates of point G?
x = 4, y = 0, so (4,0).
