Answer:
y = - 4x + 3Step-by-step explanation:
Slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-(-9)}{0-3}=\dfrac{12}{-3}=-4[/tex]
Point-slope frorm:
[tex]y-y_o=m(x-x_o)[/tex]
m = -4 ; point (0, 3) ⇒ x₀=0, y₀=3
y - 3 = - 4(x - 0)
y - 3 = - 4x
y = - 4x + 3 ← slope intercept form
Find the length of side a
a A. 12
B. 144
C. 1 194
D. 8
Answer:
12
Step-by-step explanation:
Answer:
A) 12
Step-by-step explanation:
We are gonna use the the formula for the Pythagorean Theorem
a^2 + b^2 = c^2
so that will be 5^2 + b^2 = 13^2
so now that we have the equation we just solve it
5^2 + b^2 = 13^2
25 + b^2 = 169
b^2 = 144
b = 12
Check:
5^2 + 12^2 = 13^2
25 + 144 = 169
so the answer is A) 12
Josie has a small fish tank shaped like a rectangular prism. Her fish tank measures 7 inches tall and 9 inches wide. If Josie's fish tank holds 378 cubic inches of water, how many inches long is it?
Answer:6
Step-by-step explanation:
If we know that the formula of a rectangular prism is length * width * height, and we know the height and width are 7 and 9, the length is the only thing that is left. The volume is 378, and so now we have:
length * 7 * 9 = 378. Dividing the 9 and 7, we get 378/(9*7). The length is 6.

x^2 = 2
x = sqrt 2
just question number one is good the second one could do if u feel like it
Answer:
1. n = 2
2. -4 = r
Step-by-step explanation:
-n - 7n = -16
subtract the like terms, like terms are terms that have the same variable or power. Ex: n and 7n are like terms as they both have n, however 7n and 16 are not. x^2 and x are not like terms as they do not have the same power so:
-8n = -16
divide both sides by -8
n = 2
-20 = 3r + 2r
add like terms
-20 = 5r
divide 5 from both sides
-4 = r
What is the image point of (4,-6) after a translation right 5 units and down 3 units?
Answer:
Step-by-step explanation:
I'm assuming by 'image point' you mean the translated or final point.
if it has been translated 5 units to the right, the new x-coordinate will be 4 + 5 = 9
Same for the y-coordinate. Since it has been translated down, we will subtract instead of add. therefore, it is -6 - 3 = -9
new point = (9,-9)
Hope this helps

The ratio of cars to trucks in the parking lot is 3:2. If this pattern continues, how many cars will there be when there are 150 trucks IM BEGGING FOR HELP I SWEAR
Answer: 225 cars.
Step-by-step explanation;
Think of it this way: there are 3 cars for every 2 trucks. So, if they are 150 trucks, how many cars are they? We can find this by first finding the multiple (150/2), the multiple is 75. Then multiply the multiple with the common ratio for cars, (75*3), this will be 225. So, if there are 150 trucks, then they are 225 cars.
how many points is this question
I got warned on this question for saying possible answers lol

Find the point M along the line segment from point
A(-18, -2) to point B(0,6) that divides the segment into
two congruent parts.
This is geometry
Step-by-step explanation:
X-coordinate : (-18+0)/2 = -9.
Y-coordinate = (-2+6)/2 = 2.
Hence M(-9,2).
Jose trabaja en una capinteria su jhefe le `pidio que cortara 9metros en cuatro partes de la misma longitud cuantoi deberia medir cada parte cada trozo debe medir es decuuir y cm
Responder:
2 1/4 m; 225 cm
Explicación paso a paso:
Dado:
Cortar 9 metros en 4 partes de la misma longitud;
Por lo tanto,
9 metros / 4
= 2,25 metros
Por lo tanto, cada varilla será 2.25 = 2 1/4 m
En cm;
1 m = 100 cm
2,25 metros = x
x = 100 * 2,25
x = 225 cm

What number should be added to both numerator and denominator of the ratio 29 : 36 to make
it equal to 3:42
Answer:
-1110/39 is the number
Step-by-step explanation:
We want to find the number should be added to both numerator and denominator of the ratio 29 : 36 to make it equal to 3:42
Let the number to be added be x.
Thus;
(29 + x) : (36 + x) = 3:42
The proportion symbol is essentialy a division symbol.
Thus;
(29 + x)/(36 + x) = 3/42
Cross multiply to give;
42(29 + x) = 3(36 + x)
1218 + 42x = 108 + 3x
1218 - 108 = 3x - 42x
1110 = - 39x
x = -1110/39
Which answer represents a proportional relationship?
Please help!!
1. x/x+3 + x+2/x+5
2. x+4/x^2+5x+6 • x+3/x^2−16
3. 2/x^2−9 − 3x/x^2−5x+6
4. x+4/x^2−5x+6 ÷ x^2−16/x+3

Step-by-step explanation:
72 students have vanilla ice cream and 20 students have chocolate ice cream. What is the ratio of the number of students who have chocolate to the total number of students?
Answer:
5 : 23
Step-by-step explanation:
because in total there are 92 students ( 20 + 72)
so the answer would be out of 92 ( _ : 92 )
and so then you need to find out how many students ate chocolate ice cream which was 20
so it would be 20:92
but this answer could also be simplified by 4 or 2 and u would still get the same answer but I just used 2 so 2 goes into both of them so to simplify all u do is :
20 ÷ 2 = 10
92 ÷ 2 = 46
the answer would then be 10:46
but this can also be simplified again by 2:
10 ÷ 2 = 5
46 ÷ 2 = 23
So the last and final answer would be 5 : 23

Terrence and three of his friends are sharing
of a pizza equally. What fraction of a whole pizza does each person receive?
Answer: 1/4 of the whole pizza
Step-by-step explanation:
Since there is 4 people sharing the pizza (Terrance and his three friends) we need to do 1 ÷ 4
1 ÷ 4 = 1/4.
In conclusion, each person recieves 1/4 of the pizza.
Hope this helps!
1/4 is the answer

Find the value of x so that the polygons have the same perimeter.
Answer: x=4
Step-by-step explanation:
The perimeter´s formula for this kind of polygons is
The triangle perimeter would be:
(x+2)+(x+3)+(x+3)
And the rectangle:
(x+2)+(x+2)+x+x
For them to have the same value, we should equal them:
(x+2)+(x+3)+(x+3)=(x+2)+(x+2)+x+x
Working with this:
3x+8=4x+4
x=4
