15 = 3 * 5

35 = 5 * 7

and

20 = 2 * 2 * 5

so GCF = 5

The greatest common factor, or GCF for short, is the biggest number that all of true numbers go into (this is a factor). To find the GCF, list out all of the factors 15, 20, and 35 go into.

15)

1, 3, 5, 15

20)

1, 2, 4, 5, 10, 20

35)

1, 5, 7, 35

The biggest factor that 25, 20, and 35 go into is 5. The GCF of these numbers is five

Answer:

Step-by-step explanation:

from the graph of f(x)

when x=1,f(x)=0

or f(1)=0

when f(x)=2,x=2

for g(x)

when x=6,g(x)=16

or g(6)=16

when g(x)=18,x=32

for h(x)

when x=14

h(x)=27x-7

h(14)=27×14-7=7(27×2-1)=7(54-1)=7×53=371

h(x)=-493

27x-7=-493

27 x=-493+7=-486

3 x=-54

x=-18

for p(t)

when t=94

p(t)=24

p(94)=24

p(t)=67

t=31

The equation of the line that goes through the point (1,5) and is parallel to the line 3x+5y=2 can be written in the form y=Mx+b

Llana [10]

Answer:

$y=-\frac{3}{5}x+\frac{28}{5}$

Step-by-step explanation:

step 1

Find the slope of the given line

we have

$3x+5y=2$

isolate the variable y

$5y=-3x+2\\\\y=-\frac{3}{5}x+\frac{2}{5}$

The slope of the given line is

$m=-\frac{3}{5}$

step 2

Find the equation of the line that goes through the point (1,5) and is parallel to the given line

Remember that

If two lines are parallel then their slopes are equal

therefore

we have

$m=-\frac{3}{5}$

$point\ (1,5)$

substitute in the equation of a line in slope intercept form

$y=mx+b$

$5=-\frac{3}{5}(1)+b$

solve for b

$b=5+\frac{3}{5}\\\\b=\frac{28}{5}$

substitute

$y=-\frac{3}{5}x+\frac{28}{5}$

Find the area of Rhombus if its diagonals measure 18 cm and 21 cm

Dennis_Churaev [7]

Answer:

189 cm²

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = $\frac{1}{2}$ × product of diagonals

= $\frac{1}{2}$ × 18 × 21 = 9 × 21 = 189 cm²

In the diagram, AB is parallel to DE. Also, DE is drawn such that the length of DE is half the length of AB. If sin A = 0.5, the

Anika [276]

I believe it is C, there is a geometric law that states that the opposite angles across a line with both going into parallel lines will be the same angle. Rather confusing but a video online would likely explain it better than anyone could here.

Consider the equation

sergij07 [2.7K]

Answer:

B. (-6, -9)

D. (12, 3)

Step-by-step explanation:

y=mx+b is the format for this problem.

2/3 is m and -5 is b

The b is the y-intercept which is the point where the line crosses from one side of the graph to the other horizontally. You can see at -5, that is where that happens.

Then, to find the second point, you would move the -5 up 2 and right 3 points because the slope is 2/3.

You can then look at another point of the graph to find (-6, -9)
