Answer:
y=4x
Step-by-step explanation:
if you look at the line you'll see it takes 4 x's to = 1 y, every time you go right 1 you go up 4
Answer:
The slope is 4.
Step-by-step explanation:
Step 1:
Slope can also be found by using the formula, Y2-Y1/X2-X1
In this case, our first point is the origin, so x would be 0 and y would be 0. On the second point, our x is -1, and our y is -4.
So, we can make the solution, -4-0/-1-0.
You can simplify this into, -4/-1, and then into 4.
Therefore, the slope is 4.
Step 2:
M is our slope, so in our y=mx equation our m = 4.
If you substitute in the m, you get y=4x.
Answer:
y=4x.

Pamela is 8 years older than Jiri. The sum of their ages is 62. What is Jiri's age?
Answer:
Jiri's age = 27
Step-by-step explanation:
Let's use x for Jiri's age.
Jiri's age = x
And because Pamela is 8 years older:
Pamela's age = x + 8
Since their ages added up equal 62, the equation will be:
x + x + 8 = 62
2x + 8 = 62
2x + 8 - 8 = 62 - 8
2x = 54
2x/2 = 54/2
x = 27
And because Jiri's age is x, Jiri's age will therefore be 27.
Hope this helped!
Answer:
Jiri is 27 years old.
Step-by-step explanation:
Step 1: Declare variables
Let Jiri’s age be [tex]\displaystyle x[/tex] years old.Since Pamela is 8 years older than Jiri. Then, Pamela’s age is [tex]\displaystyle{8+x}[/tex] years old.
Step 2: Form an equation
The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of [tex]\displaystyle{x+8+x=62}[/tex] (sum of Jiri’s age and Pamela’s).
Step 3: Solve for x-term - add like terms (x-term)
[tex]\displaystyle{2x+8=62}[/tex]
Step 4: Subtract both sides by 8
[tex]\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}[/tex]
Step 5: Divide both sides by 2
[tex]\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}[/tex]
Since Jiri’s age is defined as [tex]x[/tex] years old. Therefore, Jiri’s age is 27 years old.

Gina is hiking from the top of a mountain. In 24 minutes, she walks down the mountainside to a location 1,524 feet from the top of the mountain. If she walks at about the same pace, express Gina’s average change in altitude per minute.
Answer:
The change in altitude per minute is 63.5 alt/ min
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
In 24 minutes = 1524 feet
So, the average Change in altitude per minute
=1524/24
= 63.5 alt/ min
hence, change in altitude per minute is 63.5 alt/ min.

How does the Distributive Property help when combining like terms to solve the equation 4x + 6x = 30?
Answer: it helps by making the question 10 times easier
Step-by-step explanation: because 4 and 6 both have the variable X they are like terms and can be added to each other unlike 30 it doesn’t have a variable meaning 4x or 6x cannot combine with 30 because it doesn’t have the variable X. Moving on 4x+6x is 10x as you add the number but X stays the same and so 10x=30 so you divided both sides by 10 because inverse operations and you get x=3 then after you import that into the question 4(3)+6(3)=30 which is the same as 12+18=30 which is true 30=30

Answer:
On blueprint , length of room is given by feet and width is given by 10 feet.
Step-by-step explanation:
Given: On a blueprint, the scale indicates that 6 cm represent 15 feet.
We have to find the value of the length of a room that is 9 cm long and 4 cm wide on the blueprint.
Since, the scale indicates that 6 cm represent 15 feet
That is 6 cm = 15 feet
1cm = feet
Thus, the scaling factor for 1 cm is feet.
Thus, for length of a room is 9 cm long.
On blueprint , length is given by feet.
Also, given width of room is 4 cm
On blueprint , width is given by feet.
Step-by-step explanation:
Answer: so it would be the length is 27.2 feet and it is 8.88888889 feet wide or 8.9 ft wide and 27.2 feet long when its rounded i do hope i helped you and im so sorry if i didn't 27.2 goes in the box

question
how would you solve this problem
the ratio of *name*'s age to his brother's is 2:3. In ten years, the ratio would be 4:5. How old is *name* and his brother now and in 10 years?
also how would you solve it if the ratio changed to something different, ex: 1:3 to 3:5 in 10 years
Answer:
*name* is 10 years old now and brother is 15 years now
In 10 years they would be 20 and 25 respectively
Step-by-step explanation:
Let x = *name*'s age now
let y = brother's age now
The first relationship is that the ratio of their ages now is 2:3 or, in fraction form 2/3
That means x/y = 2/3
Cross multiply => 3x = 2y =>
3x - 2y = 0 [1]
10 years from now x would become x + 10 years, y would become y + 10 years and the new ratio is 4/5
So (x + 10)/(y+10 = 4/5
Cross-multiply
5(x + 10) = 4(y + 10)
5x + 50 = 4y + 40
Subtract 4y from both sides
5x + 50 -4y = 40
and subtract 50 from both sides:
5x - 4y = 40 - 50
5x -4y = -10 [2]
Eliminate y terms by multiplying [1] by 2 and subtracting [1] from that
[1] x 2
=> 2(3x - 2y) = 2 x 0
=> 6x - 4y = 0 [3]
[3] - [2]
6x - 4y - (5x -4y) = 0 - (-10)
6x - 4y -5x + 4y = 10
x = 10
Using equation [1] we get
x/y = 2/3
=> 10/y = 2/3
10 x 3/2 = y
5 x 3 = y
y = 15
So their ages are 10 and 15 now.
In 10 years they would be 20 and 25
If the ratios change we would have a different set of equations to solve for
For example if the current ratio is 1/3
Then we would get x/y = 1/3
or 3x - y = 0 [4]
and if 10 years from now the ratio is 3/5 then
(x + 10)/(y + 10) = 3/5
=> 5(x+10) = 3(y + 10)
=> 5x + 50 = 3y + 30
=> 5x - 3y = -20 [5]
And we would solve these equations to get x and y in a similar mannter
FYI the answers would be
x = 5, y = 15

HELP PLEASE!!
Answer:
-2/3
Step-by-step explanation:
You are looking the change in y over the change in x.
for y, if you go from -5 to -7, how much did it change? -2
-7 -(-5) = -7 + 5 = -2
Now look the the x's. If you from 6 to 9 how much did you change?
3
9-6 = 3
-2/3
Answer:
-2/3
Step-by-step explanation:
A slope is [tex]\frac{Change in Y}{Change in X}[/tex] and we can see that when the x value increases by 3, the y value decreases by 2. So if we plug that in, we get -2 for the Change in Y and +3 for the Change in X. Which results in the slope being [tex]-\frac{2}{3}[/tex]

Answer:
YZ=14
Step-by-step explanation:
ABCD ~ WXYZ (similar)
So all the sides are going to be in a ratio.
AD=12 AD~WZ
WZ=56 WZ~AD
[tex]\frac{AD}{WZ}=\frac{12}{56} =\frac{3}{14}[/tex]
The ratio between any side on ABCD to WXYZ is 3/14
DC=3 DC~YZ
[tex]\frac{DC}{YZ} =\frac{3}{14}[/tex]
[tex]\frac{3}{YZ} =\frac{3}{14}[/tex]
Solve for YZ
YZ=14
Given the equation −14a = 56, solve for a.
Here, we need to apply basic mathematical operations and solve the given linear equation. We get the value of a = -4.
Linear equations are expressions that involve variables and constants raised to the power of 1 (i.e., the exponent is 1) and are represented as a straight line when graphed on a coordinate 2D axis. A linear equation can be written in the form ax+ b = c where x is a variable and a,b, and c are constants .
Linear equations can have one variable (univariate) or multiple variables (multivariate). Also, these variables should not be squared, cubed, or raised to the power of any constant other than 1. For example,
1. 2x+5=0 (univariate)
2. 4z+2w=5x(multivariate)
The question given to us is an univariate linear equation where to have to apply basic rules of mathematics. Firstly we need to divide 56 by 14 which gives us 4. The negative sign gives our answer as -4.
