Answer (assuming it can be in slope-intercept form):
[tex]y = -\frac{5}{4} x-7[/tex]
Step-by-step explanation:
1) First, find the slope of the line by using the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:
[tex]m = \frac{(3)-(-7)}{(-8)-(0)}\\m = \frac{3+7}{-8-0} \\m = \frac{10}{-8} \\m = -\frac{5}{4}[/tex]
So, the slope is [tex]-\frac{5}{4}[/tex].
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute real values for the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{5}{4}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, choose any one of the given points (either one is fine, it will equal the same thing at the end) and substitute its x and y values into the formula as well. (I chose (0, -7), as seen below.) Then, isolate y to put the equation in slope-intercept form and find the following answer:
[tex]y-(-7) = -\frac{5}{4} (x-(0))\\y + 7 = -\frac{5}{4} x\\y = -\frac{5}{4} x-7[/tex]

Answer:
Step-by-step explanation:
Ms. Aluma is 165 cm tall. She wants to find her height in meters. Divide her height in centimeters by 100 to find her height in meters.
1.65 meters...........
Unit conversion is a way of converting some common units into another without changing their real value. Ms. Aluma is using the correct option.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
Given that Ms Aluma is 165 cm tall and She wants to find her height in meters. Therefore, if we divide her height in centimeters by 100 to find her height in meters.
Since 1 meter is equal to 100 cm, therefore, the method used by Ms. Aluma is correct. Therefore, the height of Unit conversion is,
Height of Ms. Aluma = 165 cm
= 165/100 meters
= 1.65 meters
Hence, Ms. Aluma is using the correct option.

Answer:
38
Step-by-step explanation:
**The sum of all the angles in a triangle is 180 degrees**
So 99 + 43 + x = 180
99 + 43 = 142 degrees
x = 180 - 142 = 38
PLEASE HELP WHAT IS THE ANSWER SHOW WORK PLEASE !!!
Answer:
d = 6.1m
n = 7km
Step-by-step explanation:
To find the variables, use tan
⇒ tan = [tex]\frac{opposite}{adjacent}[/tex]
finding d:
⇒tan 63 = [tex]\frac{d}{3.1}[/tex]
tan of 63 is 1.963
⇒ 1.963 = [tex]\frac{d}{3.1}[/tex]
multiply 3.1 on both sides
⇒ 1.963 x 3.1 = [tex]\frac{d}{3.1}[/tex] x 3.1
⇒ 6.0853 = d
round to the nearest tenth:
⇒ 6.0853 = 6.1
finding n:
⇒ tan 45 = [tex]\frac{7}{n}[/tex]
tan of 45 is 1
⇒ 1 = [tex]\frac{7}{n}[/tex]
multiply 7 on both sides:
⇒ 1 x 7 = [tex]\frac{7}{n}[/tex] x 7
7 = n
Answer:
D = 1.4, N =
Step-by-step explanation:
To get D you need to find the cosine of 63 degrees
Cosine(63) = D / 3.1
Multiply by 3.1 to isolate D :
3.1Cosine(63) = D
Put it into a calculator and you'll get 1.4.
Also, it's a 45-45-90 triangle so the 2 legs will be equal to each other.
Proof: To get N put you have to do the tangent of 45 degrees
Tan(45) = 7 / N
Now you can't to do this you have to multiply the both sides by N
N(tan(45)) = 7
Then divide both sides by (tan(45))
N = 7 / (tan(45)
Put it into the calculator and you'll get

Since the triangle is a right angled, to find one side we should use the pythagoras theorem.
The longed side of the triangle is called the hypotenuse.
In equation form: x² + y² = z²
Therefore: 12² + x² = 13²
114+x²= 169
x²= 169-114
x²= 55
x = 7.41
Therefore the length of AC = 7.41
A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 12 cm, and the base has a
radius of 3.5 cm. How much water is needed to fill 50 cups?
Use 3.14 for pi and do not round your answer.
Answer: 7693cm
Step-by-step explanation:
The volume of a cone is given as:
= 1/3πr²h
where π = 3.14
radius = 3.5cm
height = 12
Volume = 1/3πr²h
= 1/3 × 3.14 × 3.5² × 12
= 153.86cm³
Therefore, the amount of water that is needed to fill 50 cups will be:
= 153.86 × 50
= 7693cm
Which of the following tables does NOT show a proportional relationship?
Answer:
B
Step-by-step explanation:
First, a proportional ratio needs to have same equivalent fraction when simplified. So, for the option B, 5/10 can reduce to 1/2 whereas 6/11 and 7/12 do not reduce to 1/2. Therefore, the option B doesn't have a proportional relationship.

Enrique deposited $4,700 into an account. He made no additional withdrawals or deposits. Enrique earned 1.65% annual simple interest on the money in the account.
What was the balance in his account at the end of 4.5 years?
Enter the amount in the account in the box.
Step-by-step explanation:
principle (p) = $4700
rate (r) = 1.65%
time (t) = 4.5 years
interest = (p × r × t)÷100
= ($4700 × 1.65 × 4.5)÷100
= $348.975
__________________FOLLOW METhe balance in his account at the end of 4.5 years is $5048.975.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.
Simple Interest = (Principal × Rate × Time) / 100
Given;
Enrique deposited $4,700 into an account.
Enrique earned 1.65% annual simple interest on the money in the account.
Time= 4.5
Now,
SI= 4700*1.65*4.5/100
SI=348.975
Total= 4700+348.875
=5048.975
Therefore, the amount after simple interest of 1.65% will be $5048.975.
