Step-by-step explanation:
h(x) = (x + 9)(x² - 10x + 25) = (x + 9)(x - 5)²
When h(x) = 0, (x + 9) = 0 or (x - 5)² = 0.
=> x = -9 or x = 5.
Hence there are 2 distinct real roots of h(x).
8 cans of corn cost $16. What is the cost per can?
Answer:
2$
Step-by-step explanation:
If you buy 8 cans of corn and it cost you 16 dollars for all of the cans Then you can divide
Divide 16 by 8
16 divided by 8 =2
The cost of each can of corn is 2 dollars
Ans. 2
Step-by-step explanation:
Use directly proportional
X1/Y1=X2/Y2
8/16=1/X
and then solve for x

you flip a coin twice what is the probability of getting tails then getting heads
HELP ASAP
Answer: The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25% of the time you'll get heads twice in a row. But, if you've already flipped a coin 99 times, and gotten heads each time, then the odds of your next flip being heads is still just 50:50.

What is slope of the line?"The slope of tee line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"
What is y-intercept?"The point at which the graph intersects the Y-axis."
What is slope intercept form of the line?"y = mx + c, where m is the slope of the line and c is the Y-intercept."
For given question,
We have been given the graph of a line.
From the graph, we can observe that the line is passing through the points (4, 4) and (-6, 0)
Using slope formula the slope of the line would be,
[tex]\Rightarrow m=\frac{4-(-6)}{4-0}\\\\\Rightarrow m=\frac{10}{4}\\\\\Rightarrow m=\frac{5}{2}[/tex]
Also, the line intersects y-axis at y = 2
This means the y-intercept is c = 2
Using the slope-intercept form of the line the equation of the line would be,
[tex]y=mx+c\\\\y=\frac{5}{2}x+2[/tex]
Point E(-4, y) lies on the given line.
So, this point satisfies the equation of the line.
[tex]\Rightarrow y=\frac{5}{2}(-4)+2\\\\ \Rightarrow y=-10+2\\\\\Rightarrow y=-8[/tex]
Therefore, the value of y is -8

Five less than twice the value of a number is equal to three times the quantity of four more than one-half the number. What is the number?
Answer:
2x - 5 = (1/2)
4x - 10 [multiply by 2]
x - 10 = -13 [subtract 3x from both sides]
x = -3 [add 10 to both sides]
Step-by-step explanation:
The required number would be 34 which is determined by the phrase "five less than twice the value of a number is equal to three times the quantity of four more than one-half the number"
What is algebra?Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.
When broken down, these sorts of statements are not intimidating. First, consider "five less than twice the value of a number."
"Twice the value of a number" is simply 2x.
"Five less" is simply -5, so for the first part we have (2x-5)
Examine the second section next. "Three times four times more than one half the number."
"Three times the quantity" simply indicates "three times something."
4 + "one half the number" or 4 + (1/2)x is "the quantity of four more than one half the number."
So the second part is simply 3(4+x/2).
Finally, we complete the equation, (2x-5) = 3(4+x/2) and solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x = 34
Therefore, the required number would be 34.

Kate's math homework had a set of equations and a one-word problem. She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total, how many equations did she solve
Answer:
15 equations
Step-by-step explanation:
Let
Number of equations in the homework = x
There is only a one-word problem
y = amount of time used to solve the word problem
She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,
Total = 3x + y
52 = 3x + 7
Subtract 7 from both sides
52 - 7 = 3x + 7 - 7
45 = 3x
Divide both sides by 3
x = 45 / 3
= 15
x = 15 equations
Therefore, she solved 15 equations

Answer:
m ≤ 4250
Step-by-step explanation:
What we know:
Mr. Loureiro has to pay $25 plus 10 cents every mile.
The equation becomes 25 + 0.1x = 450
25 + 0.1x = 450
0.1x = 450 - 25
0.1x = 425
x = 4250
So, Mr. Loureiro can travel no more than 4250 mi. (m ≤ 4250)

There were 239 people at Travis Scott concert.Admission to get the drive in concert was $15 for adults and $5.50 for children the total cost was 2759.50 how many adults attended and how many children attended
Answer: There are 152 adults and 87 children.
Step-by-step explanation:
Let x= Number of adults
y= Number of children
As per given, we have
x+y = 239 (i)
15x+5.50y= 2758.50 (ii)
Multiply 5.50 on both sides of (i) , we get
5.50x+5.50y=1314.5 (iii)
Subtract (iii) from (ii), we get
9.5x = 1444
⇒ x = 152
Put value of x in (i) , we get
152+y=239
⇒ y= 239-152
⇒ y= 87
Hence, there are 152 adults and 87 children.
