Answer:
y = 3/7x + 54/7
Step-by-step explanation:
(not sure what S CAR is)
(-4, 6) & (3, 9)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(9 - 6) / (3 - (-4))
Simplify the parentheses.
= (3) / (3 + 4)
= (3) / (7)
Simplify the fraction.
= 3/7
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 3/7x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 9). Plug in the x and y values into the x and y of the standard equation.
9 = 3/7(3) + b
To find b, multiply the slope and the input of x(3)
9 = 9/7 + b
Now, subtract 9/7 from both sides to isolate b.
9 - 9/7 = b
[convert 9 to have a denominator of 7]
63/7 - 9/7 = b
54/7 = b
Plug this into your standard equation.
y = 3/7x + 54/7
This is your equation.
Check this by plugging in the other point you have not checked yet (-4, 6).
y = 3/7x + 54/7
6 = 3/7(-4) + 54/7
6 = -12/7 + 54/7
6 = 42/7
6 = 6
Your equation is correct.
Hope this helps!

Answer:
a)8
b)13
Step-by-step explanation:
a) ar = c
a^2+b^2=c^2
4^2+7^2=c^2
16+49 = c2
c = [tex]\sqrt{65}[/tex] ~8
b) sa= c
a2+b2=c2
7^2 + (15-4)^2
49+121 = c2
c= [tex]\sqrt{170}[/tex] = 13
I hope im right!!
Find the measure of angle 3=
Answer: 50°
Step-by-step explanation:
Since angle 3 is in a right triangle we can assume one angle is 90° and then the other missing angle will be 40°
Because you take 180°-140°(the angle next to it) which will equal 40°
Now every triangle must add up to 180°
so lets take the angles we have now
90° +40°=130°
now take that 130°
180°-130°=50°
Now check your work
90°+40°+50°=180°
Angle 3 is 50°

What is the value of x? (Answer and explanation please! :) )
Hi there!
[tex]\large\boxed{x = 11}[/tex]
From the diagram, we can see that ΔAEF, and ΔACB are similar, isosceles triangles.
Therefore:
∠B and ∠F are congruent because they are corresponding angles, and ∠B and ∠E are congruent because of equal base angles in an isosceles triangle.
Therefore:
7x - 11 = 6x
Subtract 6x from both sides:
x - 11 = 0
Add 11 to both sides:
x = 11.
Enter the unknown value in the equation.

An artical fills 1/2 of a magazine page. A corresponding photo takes up 3/8 of the article. How much of the page is taken up by the photo
Answer:
3/16
Step-by-step explanation:
If an article takes half of the page then;
1article = 1/2 of a page
3/8 of the article = x
Cross multiply
1×x = 1/2×3/8
x = 3/(2×8)
X = 3/16
Hence the photo takes 3/16 of the magazine
Find the volume of the irregular figure 3cm 7 cm 2 cm [?] cm 9 cm 11 cm 7 cm 10 cm
Answer:
672 cm³
Step-by-step explanation:
10x7x9=630
2x3x7=42
630+42=672
Which expression represents the phrase "4 more than the product of 8 and n."
So we're going to debunk this phrase.
4 more means we're adding 4 somewhere. product is the answer to a multiplication problem, so we have to multiply 8 and n. Because n is a variable, we're going to write it as 8n.
So the expression would be 8n+4.

If 2x - 3y = 24 and 3x + 4y = 2, what is the value of x - y ?
Answer:
10
Step-by-step explanation:
2x - 3y = 24 ------ (1)
3x + 4y = 2 ------ (2)
(1) × 4,
8x - 12y = 96 ------ (3)
(2) × 3,
9x + 12y = 6 ------ (4)
(3) + (4)
17x = 96 + 6
= 102
x = 102 ÷ 17
= 6
Sub x = 6 into (2),
3(6) + 4y = 2
18 + 4y = 2
4y = 2 - 18
= -16
y = -16 ÷ 4
= -4
Therefore,
x - y = 6 - (-4)
= 6 + 4
= 10
i hope this helps you !!

A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression
(0.85).32 represents the final price of the cake in dollars.
Answer:
$27.2
Step-by-step explanation:
A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression (0.85).32 represents the final price of the cake in dollars.
This is explained in the calculation below
= A cake that costs $32 is on sale for 15% off
The amount off the cake is calculated as
= 15% of $32
= 15/100 × 32
= $4.8
The amount he is paying for the cake =>$32 - $4.8
= $27.2
The above expression is obtained as
(0.85).32
= (100% - 15%) × 32
=( 1 - 0.15) × 32
= 0.85 × 32
= $27.2
The final price of the cake = $27.2

His reasoning is illogical because whether or not an expression has a term that is being subtracted isn't relevant; technically there are an infinite amount of ways to represent a value. Plus you can just compute the expressions and see that they're equal:
6x-2x+4 = 4x+4
4(x-1) = 4x+4
30
The two expressions are equal because when you compute the expression 4(n+3)-(3+n) , you get 3n+9:
4(n+3)-(3+n) = 4n+12-3-n = 3n+9
31
The two expressions are equal because when you compute the expression 2(2n-1), you get 4n-2.
2(2n-1) = (2)(2n)+(2)(-1)=4n-2

The school bus has 18 rows of seats. There are 4 students in each row. Each student has 3 books to bring home. How many students are on the bus?
Answer:
Step-by-step explanation:
*The part about how many books per student is irrelevant to the question*
All you need to do is multiply 18 rows by 4 students per row.
18 * 4 = 72 total students on bus
Answer:
72
Step-by-step explanation:
18 times 4 equals 72. If there are 4 students in EACH row out of all the 18, then there is 72 kids on the bus.
