Answer:
y = 25
Step-by-step explanation:
y = 4x - 7
y = 4(8) - 7
y = 32 - 7
y = 25
The value of y is 25 for y=4x-7 when x is 8.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given equation is y=4x-7
y equal to four times of x minus seven.
We need to find value of y when x is 8
y=4x-7
Put x as 8 in the above equation
Multiply four time of eight and subtract seven from the value
y=4(8)-7
The value we get when four time of eight is thirty two
y=32-7
Thirty two minus seven is twenty five
y=25
Hence the value of y is 25 for y=4x-7 when x is 8.

Given are the slopes of several lines. Indicate whether each line is horizontal, vertical, rises from left to right, or falls from left to right.
Answer:
Rises from left to rightVertical LineHorizontal LineFalls from left to rightStep-by-step explanation:
Keep in mind we read graphs from left to right just like how we read and write.
A positive slope will be increase from left to right. A negative slope with decrease left to right. A vertical line will have a undefined slope.A horizontal line will have a slope of 0.We can use those tips to solve the problem.
Option A:
4/5 is a positive slope so it will rise from left to right.
Option B:
No slope automatically means "undefined" so that falls in the definition of a vertical line.
Option C:
A slope of 0 is defined as a horizontal line.
Option D:
-4/5 is a negative slope so it will fall from left to right.

Find the coordinates of the midpoint of a segment with given endpoints
Answer:
[tex]\boxed {\boxed {\sf ( - \frac{9}{2}, -1) \ or \ (-4.5, -1) }}[/tex]
Step-by-step explanation:
We are asked to find the midpoint of a line segment. When you find the midpoint, you essentially find the average of the x-coordinates and the y-coordinates. The midpoint formula is:
[tex](\frac {x_2+x_1)}{2}, \frac{y_2+y_1}{2})[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the endpoints of the line segment. we are given the endpoints R (-6, 1) and S (-3, -3). If we match the value and the corresponding variable we see that:
x₁= -6 y₁= 1 x₂= -3 y₂= -3Substitute the values into the formula.
[tex]( \frac{-3 + -6}{2} , \frac{ 1+ -3}{2} )[/tex]
Solve the numerators.
-3 + -6 = -9 1 + -3 = -2[tex](\frac {-9}{2}, \frac {-2}{2})[/tex]
Divide.
[tex]( - \frac {9}{2}, -1})[/tex]
The fraction can also be written as a decimal.

The midpoint of the line segment RS is (-9/2, -1) or (-4.5, -1).

The answer is Either B or C, But I'm going with ASA which is B.
explanation: congruent angles are about 48° they could be much more higher but in this case they aren't. And as you could see congruent angles aren't like that.
The rule is If two angles have the same measure then they are congruent.
Congruent angles are marked with the same number of "arcs".
Note: This picture isn't mine, it's an example of what a congruent angle could look like.

What is the probability of drawing a red card or a queen from a standard deck of 52 cards?
7 over 13
15 over 26
1 half
1 over 26
The probability for red card or queen is given as 15/26. The correct option is (B).
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lie in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
The total number of red cards in the deck is 26.
And, the number of queens in the deck is 4.
Now, the probability of getting red card is given as,
P(red cards) = Number of red cards ÷ Total number of cards
⇒ P(red cards) = 26/52 = 1/2.
Similarly, the probability of queen is,
P(queen) = 4/52 = 1/13
Thus, the probability of drawing a queen or red card is given as,
P(red card or queen) = P(red card) + P(queen)
⇒ P(red card or queen) = 1/2 + 1/13 = 15/26.
Hence, the probability of drawing a red card or a queen from a standard deck of 52 cards is 15/26.

Q9) There are 4,000 students attending a local community college and the number of students is increasing by 5% each year. How many students will attend the college in 4 years?
Answer: 4,862 students will attend the college in the next four years
Step-by-step explanation: If the college starts out with 4,000 students you need to find 5% of 4,000. To do this you would multiply 4,000 by 0.05, you should get 200. So 5% of 4,000 is 200 so the next year there will be 200 more students then last year meaning the next year will have 4,200 student. So now you'll repeat the same step multiply the number of students (now 4,200) by 0.05, then add the answer to the number of students from the previous year. So year two is:
4,200x0.05=210
4,200+210=4,410
repeat these steps till you have four years worth.

What is Unitary method?"It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
Total money = $225.00
Cost of one ball =$55
So, remaining money after buying the ball
=225- 55
= $170
Now,
game of bowling costs $3.50,
So, number of bowling can be played is
=170/3.5
=48.75
= 48 bowling

The derivative of (x^2 +1)(x^3+ 1) (by definition and basic rule)
Answer:
f'(x) = 5x^4 + 2x + 3x^2
Step-by-step explanation:
To find the derivative of this equation we can do two things.
One method is to use the product rule, which states that when f(x) consists of two functions multiplied to each other (meaning f(x) = g(x) * h(x)), the derivative is f'(x) = g'(x)*h(x) + g(x)*h'(x). In simple language, the derivative is found by finding the derivative of x² + 1 and multiplying it with the normal function of x³ + 1, after which you add the product of the nnormal function of x² + 1 and the derivative of x³ + 1.
it might be clearer when I show you:
[tex]f(x) = (x^2 + 1)(x^3 + 1)\\f'(x) = (2x)(x^3 + 1) + (x^2 + 1)(3x^2)\\Simplify:\\f'(x) = 2x^4 + 2x + 3x^4 + 3x^2 = 5x^4 + 3x^2 + 2x\\[/tex]
If you are not familiar with this rule you can first write out the function and then use the basic rule:
[tex]f(x) = (x^2 +1)(x^3+1) = x^5 + x^2 + x^3 + 1\\f'(x) = 5x^4 + 2x + 3x^2[/tex]
If you need any further help please say so in the comments! I hope this helps! If the steps seem complicated, I suggest you could revise expanding brackets (the first step of the second method) and the basic rules of deriving, but feel free to reach out if you struggle afterwards still

how would i do this? it’s algebra 1
Answer:
So the first step is asking you to write the explanation on your own paper (Easy! :)
The whole equation is designed for you to get the variable "x" by itself so that you know what number it is equal to. In order to do this you need to follow the steps.
So for the second step you need to add 1 to both sides. This step is so that you can get rid of the 1 on the left side, to do this you need to add 1 because this will cancel out on the left side since you are substracting it. BUT if you add one on the left side, you also need to add it to the right side!!! (Whatever you do on one side of the equal sign you need to do on the other side)! So add one on both sides this will get rid of the 1 on the left and turn the 6 to a 7 on the right side.
NEXT STEP (Multiply both sides by -2) So (-1/2) is the same as saying 1 divided by -2 which is -0.5 as a decimal. If you want to cancel out a fraction you want to multiply it by the denominator (aka bottom number), in this case that number is -2. So if you multiply (-1/2) by -2 this cancels that fraction out on the left side and it disappears, BUT you must do it on the right side too! So you multiply 7 by -2 which is equal to -14.
Now you're left with 5x = -6! Your final step is to get rid on the 5 on the left side. To do this you simply divide it by 5 so that it cancels out on the left side and you're left with x. BUT you still divide on the right side, so x is equal to (-6/5).
I hope this helps!
