Answer:
To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.
- x + 2 = - 1 + 2 = 1
Now - 3 < 1
Thus (1, - 3) is not a solution
Step-by-step explanation:

Step-by-step explanation:
A projector displays an image on a wall. The area (in square feet) of the projection is represented by x^2-8x+15
a. write a binomial that represents the height of the projection
b. find the perimeter of the projection when the height of the wall is 8 feet
Answer:
a. (x - 5) ftb. 16 ftStep-by-step explanation:
The area given:
x² - 8x + 15a. The height is the factor of the area:
x² - 8x + 15 = x² - 3x - 5x + 15 = x(x - 3) - 5(x - 3) = (x - 3)(x - 5)The width is x - 3, so the height is x - 5
b. The perimeter formula:
P = 2(x - 3 + x - 5) = 2(2x - 8) = 4x - 16The height of the wall is 8 ft:
x = 8The perimeter is:
P = 4*8 - 16 = 32 - 16 = 16 ftIs a bucket used to carry water more likely to have a capacity of a pint or a gallon

cuanto es 5 + 2d = 9
Answer: d=2
Step-by-step explanation:
Given
5+2d=9
Subtract 5 on both sides
5+2d-5=9-5
2d=4
Divide 2 on both sides
2d/2=4/2
d=2

Is 16=3 one, no, or many solutions?
And if the lines were graphed, would they be the same line, intersecting, or parallel
Answer:
No solutions; parallel
Step-by-step explanation:
The equations x=16 and x=3 both have a slope of 0. So when graphed, they would be parallel and there are no solutions between parallel lines.

Step-by-step explanation:
Answer:
Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation:
[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],
which gives us k = 6, and the correct answer 6, 8, and 10.
Step-by-step explanation:
Jared wanted three consecutive even integers, whose sum is 4 times the first integer.
He let k represent the first integer and wrote:
[tex]k+(k+1)+(k+2)=4k[/tex]
We can solve this first. Combine like terms:
[tex]3k+3=4k[/tex]
So:
[tex]k=3[/tex]
This means that our sequence will be 3, 4, and 5, which is not correct since we have odd integers.
Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation*:
[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],
which gives us k = 6**, and the correct answer 6, 8 , and 10.
To verify, 6 + 8 + 10 = 24.
And 6(4) = 24, so our answer is correct.
**To solve, we can combine like terms:
[tex]3k+6=4k[/tex]
So:
[tex]k=6[/tex]
*The reason we use (k + 2) instead of (k + 1) is because (if k is an even number), then adding 2 guarantees another even number. If we added only 1, we will get odd numbers.

Find the length of a
Help plz ASAP
Answer:
Hey there!
Your answer is c)
Answer:
2√5
Step-by-step explanation:
The triangle that's shown on the page is a special isosceles right triangle with angle measures of 45° - 45° - 90°
Since one of the side length that sees 45° angle measure is 2√5 the other also has to be equal to this value so the answer is 2√5

Answer:
J probably
Step-by-step explanation:
When multiplying the rectangle's sides by 1.5 you get the rectangle F.
When multiplying the sides by 1/4 you get G.
When multiplying by 1.25 you get H.
To get J, you would need to muliply 8 by 1.25 and 2 by 2. There is no scale factor that would result in the rectangle ABCD turning into J.
A medical school admits 86 new applicants every year, let y represent the number of years and a represent the total of admitted applicants
Answer:
a = 86y
Step-by-step explanation:
Given:
Number of applicants per year = 86
Find:
Equation represent total applicants
Computation:
Assume;
Total number of years = y
Total number of applicants = a
So,
Total number of applicants = Number of applicants per year x Total number of years
a = 86 x y
a = 86y
How do i do square root?
Divide the number by your guess. Now you have two numbers that multiply to get your original number. Take the average of these two numbers. This becomes your second guess for the square root.

you can find it with do its LCM.
the grocery store sells 4 pints of strawberries for 13.80 how much does it cost per pint
Answer:
3.45
Step-by-step explanation:
if 4 pints are 13.80 you would have to divided 13.80 by 4 and 4 by 4 to get 1 over blank. The denominator would be 3.45 which would be the amount 1 pint cost. If you don't want to do it as fractions you can simply divide 13.80 by 4.

I need help on my warm up!! pls thx!
Step-by-step explanation:
[tex] \tt{30.16 = 17.56 + 5x} [/tex]
Swap the sides of the equation :
⤑ [tex] \tt{17.56 + 5x = 30.16}[/tex]
We want to remove the 17.56 first.
Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :
⤑ [tex] \tt{5x + 17.56 - 17.56 = 30.16 - 17.56}[/tex]
Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.
⤑ [tex] \tt{5x = 12.6}[/tex]
Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.
⤑ [tex] \tt{ \frac{5x}{5} = \frac{12.6}{5}} [/tex]
Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.
[tex] \pink{ \boxed{ \boxed { \tt{Our \: final \: answer : \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}[/tex]

Answer: 1/14, 2/28.
Step-by-step explanation:
2/7 x 0.25 =
Convert 0.25 into a fraction.
0.25 = 1/4.
Multiply the numerators together and then multiply the denominators with each other.
1/4 x 2/7 = 2/28.
Therefore, the answer is 2/28, but it can also be simplified to 1/14. So the answer is the first one, or 1/14.
Answer:
1/14 or A
Step-by-step explanation:
0.25 as a fraction is 1/4
1/4 x 2/7 = 2/28, simplify to become 1/14, and there is your answer
