A line has a slope of 5 and passes through the point (1, 0). What is its equation in
slope-intercept form?
Answer:
y=5x-5
Step-by-step explanation:
find y-intercept:
0=1(5)+b
b=-5
Answer:
y = 5x - 5
Step-by-step explanation:
y = mx + b
m = 5
b = ?
Plug in the coordinates
0 = 5(1) + b
0 = 5 + b
-5 = b
Finally:
y = 5x - 5

Answer:
x = 12
Step-by-step explanation:
We know that the integers are consecutive. This means that they can be written as:
x, x + 1, and x+2.
First Integer: x
Second Integer: x + 1
Third Integer: x + 2
It is also given that the sum of the first integer and twice the second is 80 minus three times the third.
Write as an equation:
First Integer + 2(Second Integer) = 80 - 3(Third Integer)
Substitute:
x + 2(x+1) = 80 - 3(x+2)
Multiply:
x + 2x + 2 = 80 - 3x - 6
Simplify:
3x + 2 = 74 - 3x
Add 3x to both sides of the equation:
6x + 2 = 74
Subtract 2 from both sides of the equation:
6x = 72
Divide both sides of the equation by 6:
x = 12
Let me know if you have any questions about my explanation!
Answer:
Smallest Integer = 12Step-by-step explanation:
According to question ,
• First Integer → x
• Second Integer → x + 1
• Third Integer → x + 2
Now question says that the sum of the first and twice the second is 80 minus three times the third that means ,
→ x + 2 ( x + 1 ) = 80 - 3 ( x + 2 )
→ x + 2x + 2 = 80 - 3x - 6
→ 3x + 2 = -3x + 74
→ 3x + 3x = 74 - 2
→ 6x = 72
→ x = 72/6
→ x = 12
Hence , value of x is 12 that means :
→ x = First Integer = 12
→ x + 1 = Second Integer = 13
→ x + 2 = Third Integer = 14
In all of these x is the smallest integer and hence 12 is the correct answer .

Find the GCF of the pair of monomials.
32a,48a
Answer:
The greatest common factor (GCF) of these two monomials is [tex]16\, a[/tex].
Step-by-step explanation:
Rewrite [tex]32\, a[/tex] and [tex]48\, a[/tex] as the products of the variable [tex]a[/tex] and and prime number factors:
[tex]32\, a = 2 \times 2 \times 2 \times 2 \times 2 \times a = 2^{5}\times a[/tex] (where [tex]2[/tex] is a prime factor.)[tex]48\, a = 2 \times 2\times 2 \times 2 \times 3\times a = 2^{4}\times 3\times a[/tex] (where [tex]2[/tex] and [tex]3[/tex] are both prime factors.)Write an expression for the GCF of these two monomials in terms of these factors ([tex]2[/tex]'s, [tex]3[/tex], and [tex]a[/tex].) Try to include as many of each factor as possible, as long as the resulting product is present in both monomials.
For example, there are five factor [tex]2[/tex]'s in the first monomial but only four in the second monomial. Therefore, include the factor [tex]2\![/tex] in the GCF for only four times.
The factor [tex]a[/tex] appeared once in both monomials. Hence, include [tex]a\![/tex] for one in the expression for the GCF.
On the other hand, the factor [tex]3[/tex] is found in the second monomial but not in the first. Therefore, this factor should not be included in the expression for the GCF.
Therefore, the expression for the GCF would be:
[tex]2 \times 2\times 2\times 2 \times a = 16\, a[/tex].
In Chapter 4 #25, you compared the distributions of innings per game for 24 starting pitchers in 1958 and 99
starting pitchers in 2008. Do the data provide convincing evidence that pitchers in 1958 had a greater ability to
stay in games?
a. State the hypotheses we are interested in testing.
b. The mean innings per game in 1958 was 6.70 and the mean innings per game in 2008 was 6.05 for a test
statistic of 6.70 – 6.05 = 0.65. Describe how to simulate the distribution of the test statistic, assuming that
pitchers in both years have the same ability to stay in games.
c. A simulation was conducted assuming that pitchers both years have the same ability to stay in games. In each
of the 100 trials, the difference in means was calculated and recorded on the dotplot below. Use the dotplot to
estimate and interpret the p-value.
d. Based on the p-value, make an appropriate conclusion.
e. If there is convincing evidence that pitchers in 1958 did have a greater ability to stay in games, does that mean
today’s pitchers are wimpier? What other possible explanations could there be?

a. Ha Pitchers in 1958 had the same ability to stay in games
Ha Pitchers in 1958 had a greater ability to stay in games
b. I don't know how to do this one
c. The P value is 0%
d. Since the P value is 0%
e. Since the P value is 0% we reject the null hypothesis and except alternative hypothesis. The alternative hypothesis being that the pitchers in 1958 had a greater ability to stay in games

Jasmine is buying cakes for a party. One chocolate cake costs $7, and one lemon cake costs $5. If Jasmine needs to buy 18 cakes and has $110 to spend, how many lemon cakes can she buy?
Set up and solve a system of linear equations to model how to determine the number of lemon cakes Jasmine can buy for the party.
Answer:
Step-by-step explanation: Am not sure if this is the answer you guys are looking for but my in 9th grade and this is how my math teacher taught me how to do it.one chocolate cake=?=x
one lemon cake=?=y
$270 spent
need to buy total of 18 cakes
1-chocolate cake =$7
lemon cake = $5
cakes 18=x+y
money $110=$7x+$5y
When i graphed it on the demos calculator i got (10,8).
So 10= the number of chocolate cake brought and 8= the number of lemon cake brought
The number of lemon cakes Jasmine can buy for the party is 8.
System of linear equationsTwo equations can be deduced from the question:
a + b = 18 equation 1
$7a + $5b = $110 equation 2
Where:
a = number of chocolate cakes boughtb = number of lemon cakes boughtDetermining the number of lemon cakes that can be bought
In order to determine the number of lemon cakes that can be bought, take the following steps:
Multiply equation 1 by 7
7a + 7b = 126 equation 3
Subtract equation 2 from equation 3
2b = 16
b = 8

I NEED IT ASAP How do the signs of the coordinates affect the position of a point in the coordinate plane
Answer:
Each point will plot to only one place in the coordinate plane. So, I don't know what you mean by plotting anywhere and you'll get the same result. You won't
Step-by-step explanation:
Answer:
The signs of a point's coordinates affect where the point is on a coordinate plane because an X-coordinate being negative or positive tells how far to the right or left of the Y-axis a point is. Vice versa, the Y-coordinate being positive or negative says how far above or below the X-axis a point is on a coordinate plane.

12 = x(x - 4)
12 = x² - 4x
x² - 4x - 12 = 0
x² - 6x + 2x - 12 = 0
x( x - 6) + 2(x - 6) = 0
(x + 2)(x - 6) = 0
x = -2, 6
Since, measure of the sides can't be negative, x can not be negative.
Therefore, x = 6 will be the answer.
Answer:
x = 6

what is half 7minutes and 24 seconds
Answer:
3 minutes and 42 seconds
Step-by-step explanation:
So I would convert that minute into seconds
7*60=420
So 420+24=444
Divide by 2
444/2=222
Now divide by 60 to convert it back to minutes
222/60= 3.7
3.7 minutes or
7/10*60=42
3 minutes and 42 seconds

Step-by-step explanation:
Vertical angles are congruent so:
7x=8x-12
Subtract 7x from both sides:
0=8x-12
Add 12 to both sides:
8x=12
Divide both sides by 8:
x=1.5 or
x= 3/2
think about the process the relationship between x and y is represented by the equation y=19x how can you decide if the equation represents a porportianl relatingjip
Answer:
Since the value is always multiplied by the same factor(19), the relationship is proportional.
Step-by-step explanation:
To see if the equation represents a proportional relationship, we see if the division of y by x is always the same
[tex]x = 1, y = 19*1 = 19[/tex]
[tex]x = 2, y = 19*2 = 38[/tex]
[tex]x = 3, y = 19*3 = 57[/tex]
So
[tex]\frac{57}{3} = \frac{38}{2} = \frac{19}{1} = 19[/tex]
Equal, so proportional
