Answer:
5
Step-by-step explanation:
you keep the sign of the first number
change the minus sign to addition
and the 7 to a positive
-2 +7
is the same as 7 - 2 if you switch the term
— 2х + Зу = 6
solve for y
Answer:
y = 2/3x+3
Step-by-step explanation:
-2x+3y=6
you add 2x to the other side 3y=2x+6
and divide by 3
y = 2/3x+2

A gardener can trim a square lawn of side 50 metres in 4 hours. At the same rate, how long will it take him to trim a square lawn of side 25 metres?
A)1 hour
B)2 hours
C)2 hours 30 minutes
D)3 hours
Answer:
2 hours
Step-by-step explanation:
50 metres / 4 hours = 25 metres / x hours
cross multiply both sides
50x = 25(4)
50x = 100
divide 50 both side
x = 100/50
x = 2 hours

what is the answer to this radical equation
[tex]\sqrt{x + 13=7}[/tex]
Answer:
x = 36
Step-by-step explanation:
Given
[tex]\sqrt{x+13}[/tex] = 7 ( square both sides )
([tex]\sqrt{x+13}[/tex] )² = 7²
x + 13 = 49 ( subtract 13 from both sides )
x = 36
[tex]\sqrt{x+13}=7\\[/tex]
To solve the radical equation, completing the square all whole equation.
[tex](\sqrt{x+13})^2=7^2\\[/tex]
As defined, [tex](\sqrt{x})^2 =|x|[/tex]
Therefore, [tex](\sqrt{x+13})^2=|x+13|=x+13[/tex] (Although Absolute Function gives 2 conditions, however - domain of radical function must be greater than or equal to 0. Meaning x < 0 for another condition doesn't apply.)
[tex]x+13=49\\x=49-13[/tex]
Move 13 to subtract.
[tex]x=36[/tex]
Therefore, the answer is x = 36.
If y=32 when x=8, find y when x=30.

Answer:

Step-by-step explanation:
if the two triangles are similar, that means that they are proportional to each other.
If you look at how they are shaped, they look the same, just one is smaller.
When you compare the two, you see that on triangle EFU, side EU corresponds with side VU on triangle VWU
EU = 7 and VU = 35
now divide so see what the multiplying factor is
35/7 = 5
so, when you divide the values on triangle VWU by 5, you get the values for triangle EFU
35/5 = 7
side UW corresponds with side UF
UW = 55 and UF = ?
55/5 = 11
Side UF = 11

Answer:
y=2x−1
Explanation:
First, we need to determine the slope of the line. The formula for determining the slope of a line is:
m=y2−y1x2−x1
where m is the slope and the x and y terms are for the points:
(x1,y1) and (x2,y2)
For this problem the slope is:
m=3−−12−0
m=3+12m=42m=2
Now, selecting one of the points we can use the point slope formula to find the equation.
The point slope formula is:
y−y 1=m(x−x1)
Substituting one of our points gives:
y−1=2(x−0)y+1=2x
Solving for y
to put this in standard form gives:
y+1−1=2x−1
y+0=2x−1
y=2x−1

Factor −6
out of −18a−30 Please I’m really frustrated
Answer:
-6(3a + 5)
Step-by-step explanation:
Factoring -6 from 18a, you will be left with 3a because -6× 3a will give you 18a
Also factoring -6 from 30, you will be left with 5 because -6 ×5 = -30.
so -18a -30
-6( 3a + 5)
Christopher is hanging Christmas lights along the perimeter of his house by using his 15 foot ladder. The base of the ladder is placed 4 feet away from the base of his house. How far up the house does his ladder reach?
Answer:
14.45 feet
Step-by-step explanation:
The set up is a right angled triangle;
The length of the ladder = hypotenuse = 15foot
The base of the ladder is the adjacent = 4feet
The height of th house is the opposite = x
Using the pythagoras theorem;
hyp² = opp² + adj²
15² = opp²+4²
opp² = 15²- 4²
opp² = 225 - 16
opp² = 209
opp = 14.45feet
Hence the ladder reaches 14.45 feet up the house

Step-by-step explanation:
The correlation coefficient of the set of data is 0.9957.
What is coefficient correlation? What is the general equation of a Straight line?Correlation coefficient measures the strength and direction of the relationship between two variables. Following is the formula to calculate the correlation coefficient -
[tex]$r =\frac{\sum\left(x_{i}-\bar{x}\right)\left(y_{i}-\bar{y}\right)}{\sqrt{\sum\left(x_{i}-\bar{x}\right)^{2} \sum\left(y_{i}-\bar{y}\right)^{2}}}[/tex]
r → correlation coefficient.
[tex]$x_{i}[/tex] → values of the x-variable in a sample.
[tex]$\bar{x}[/tex] → mean of the values of the x-variable.
[tex]$y_{i}[/tex] → values of the y-variable in a sample.
[tex]$\bar{y}[/tex] → mean of the values of the y-variable.
The general equation of a straight line is -
y = mx + c
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a runner times herself to see how long it takes her to run different distances. The table shows the runner's times (in minutes) for running several distances (in miles) -
