Answer:
(5, 20)
Step-by-step explanation:
We can find the slope of the line
m = (y2-y1)/(x2-x1)
= (40-0)/(10-0)
= 40/10
=4
Since the line goes through (0,0) the y intercept is 0
y = mx+b
y = 4x
Lets check the points by substituting into the equation
40, 10) 10 = 4*40 10 =160 no
(–5, –10) -10 = 4*-5 10 = -20 no
(5, 20) 20 = 4*5 20 = 20 yes
(–10, –20) -20 = 4*-10 -20 = -40 no
Can someone plz help me ?

Triangles ABC and DEF are similar. Find x.
Answer:
8.57
Step-by-step explanation:
We can calculate the value of x using similarity ratio
11/7 = (15 + x)/(15) cross multiply expressions
105 × 7x = 165 subtract 105 from both sides
7x = 60 divide both sides by 7
x = 8.57 approximately

The length of a rectangle is 15 less than three times the width. The perimeter of the rectangle is 178 centimeters. What is the length of the rectangle?
Answer:
40.5in
Step-by-step explanation:
Given data
Let the width be x
L= 3x-15
Perimeter= 178cm
We know that
P=2L+2W
substitute
178= 2(3x-15)+2x
open bracket
178=6x-30+2x
collect like terms
178=8x-30
178-30= 8x
148= 8x
divide both sides by 8
x= 148/8
x=18.5 in
but L= 3x-15
L= 3*18.5-15
L=55.5-15
L=40.5 in
Hence the length is 40.5in

help please
Answer:
There's no solution to this equation, when 2 equations have the same slope but different y-intercepts, they're parallel. This means they never intercept and there is NO solution and we can't solve for x.
On Monday 430 students went on a trip to the zoo all 9 buses were filled and seven students had to travel in cars how many students were in each bus
Answer: 47 students
Step-by-step explanation:
430 students went on a trip with the majority of them going on buses.
7 students however, had to use cars.
The number of students who used buses are:

= 423 students
The number of students in each bus is:
= No. of students taking buses / no. of buses
= 423 / 9 buses
= 47 students

A lemonade recipe calls for 1/4 cup of lemon juice for every cup of water what does x represent
Answer:
X represents the amount of cups of water
Answer:
x represents the number of cups of water.
Step-by-step explanation:
The recipe calls for ¹/₄ cups of lemon juice per 1 cup of water. This means the amount of lemon juice is dependent on the amount of water. In most functions, x is the independent variable and y is the dependent variable. Since the number of cups of lemon juice is dependent on the number of cups of water, the lemon juice represents y...
...and the water represents x.
