Find the solution of the system of equations.
X – 10y = 18
- 6x – 10y = 32​

Answer:

0.9

Step-by-step explanation:

you do 1.6 x 4= 6.4

so we know that we have to do 3.6 divided by 4 = 0.9

so 0.9 is x

Answer:

28.2

Step-by-step explanation:

1638 ÷ 58 = 28.2413793103

rounded to 1 significant figure = 28.2 as 4 rounds down

hope this helps

Answer:

Actually, an infinite number. Put infinite number.

Solving for it, you will get y=y & 6.6 repeating.

y is a free variable from a free column. So it can really be anything.

Answer:

an infinite number of solutions

Step-by-step explanation:

1st method - elimination

2nd method - substitution

Answer:

No, they are not equivelent.

Step-by-step explanation:

If we solve both of them :

3:6 = 3/6

3/6 = 1/2

1/2 = 1:2

6:3 = 6/3

6/3 = 2/1 (just 2!)

2/1 = 2:1

So, they aren't the same because they aren't the same fraction and they don't simplify to the same answer :)

Answer:

(0,0)

Step-by-step explanation:

The y-intercept is where the parabola crosses the y-axis. The y-intercept is expressed as a coordinate pair, where x is always equal to 0 because the y-axis exists where x=0.

There are 2 ways to find the y-intercept of a function. The first way is to plug in 0 for x because you know that x=0 at the y-intercept. Then, solve for y.

[tex]y=0^2+3(0)[/tex]

y=0

The second, and easier, way to find the y-intercept is to use logic. Since you are plugging in 0 for x, all terms that have variables will equal 0. This means that all that is left are the constants. So, the easiest way to find the y-intercept is to just simplify the constants. Whatever this equals will be the y-value of the y-intercept. Since there are no constants written in this equation, the constant must be 0. If 0 is the constant, then that must mean that the y-value of the intercept is 0.

Answer:

6565 = 1010(4) + 2525

Step-by-step explanation:

so the equation would be

6565 = 1010x + 2525

x = 4 because

1010 (4) = 4040

and 4040 + 2525 = 6565, so

6565 = 1010(4) + 2525

Answer:

6x+16

Step-by-step explanation:

x+20+5x-4

Gather the like terms: (x+5x)+(20-4)

= 6x+16

Step-by-step explanation:

the point-slope form is

y - y1 = a(x - x1)

with "a" being the slope, (x1, y1) being a point on the line.

so, we have here

y - 1/2 = 4(x - 3/8)

simplifying this gives us then the slope-intercept form

y = ax + b

with b being the y-intercept.

so, we get

y - 1/2 = 4x - 4×3/8 = 4x - 3/2

y = 4x - 3/2 + 1/2 = 4x - 2/2 = 4x - 1

so,

the first, second and forth statements are true, the third is false.

Answer:

20.3

Step-by-step explanation:

4 = 0.25(w-4.3)

4= 0.25w- 1.075

5.075= 0.25w

(4/1)*5.075 = 1/4w *(4/1)

20.3 = w

Answer:

Combina los términos multiplicados en una sola función

4=0.25 (w-4.3)

4=1(w-4.3)/4

Multiplica por 1

4=1 (w-4.3) /4.

4=w-4.3/4

Multiplica todos los términos por el mismo valor para eliminar los denominadores de las funciones

4=w-4.3/4

4.4=4.w-4.3/4

Cancela los términos multiplicados q estén en el denominador

4.4=4.w-4.3/4

4.4=w-4.3

Multiplica los números

4-4=w-4.3

16=w-4.3

Rta = w= 20.3

Answer:

2p - 4

Step-by-step explanation:

Hello!

Let's start by deciphering what the wording is saying.

So we see he reads 4 less than 2 times the number of pages he read yesterday.

Note the words I put in bold. They're in bold because they signal our operations.

Note the fragment I underlined. It is underlined because that underlined portion refers to our variable, p.

So the amount of pages read is 4 less than 2 times p.

Well, 2 times p is 2p, and 4 less than 2p is 2p - 4

Answer:

x = 101 degrees

Step-by-step explanation

Answer:

x = 101°

Step-by-step explanation:

x and are same- side interior angles and sum to 180° , then

a + x = 180° , that is

79° + x = 180° ( subtract 79° from both sides )

x = 101°

Answer:the 2nd

Step-by-step explanation:

The statement proves that quadrilateral HIJK is a kite is  IH = IJ = 3 and JK = HK = [tex]\sqrt{29}[/tex] and IH ≠ JK and IJ ≠ HK.

Given

On a coordinate plane, kite H I J K with diagonals is shown.

Point H is at (negative 3, 1), the point I is at (negative 3, 4), point J is at (0, 4), and point K is at (2, negative 1).

A quadrilateral is called a kite with two pairs of equal adjacent sides but unequal opposite sides.

Firstly calculating the length of the sides of the kite using the following formula;

[tex]\rm Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For a kite quadrilateral,  HIJK will be a kite, if it's siding IJ = IH

From the graph length of I H = 4 - 1 = 3 units

Length of IJ = 0 - (-3) = 3 units

Therefore, IJ = IH = 3 units

Sides HK should be equal to JK

Length of HK is;

[tex]\rm HK =\sqrt{(1-(-1))^2+(2-(-3))^2} \\\\HK=\sqrt{(1+1)^2+(2+3)^2} \\\\HK=\sqrt{(2)^2+(5)^2\\} \\\\ HK =\sqrt{4+25} \\\\HK= \sqrt{29}[/tex]

Hence, the statement proves that quadrilateral HIJK is a kite is  IH = IJ = 3 and JK = HK = [tex]\sqrt{29}[/tex] and IH ≠ JK and IJ ≠ HK.

Answer: 20.25ft

1. Find what 8 inches in scale equal for the height of the house.

we will do this step by multiplying.

2in=4.5

8=?

to find...

2x4=8

so

4.5x4=18

2. Find what 1 inch on the scale is equal to for the height of the house.

we will do this by dividing 4.5 by 2

4.5/2=2.25

3. Add both the values for step 1 and 2.

we will do this by just adding them both

18+2.25=20.25

This is our answer, because first we found the value of 8 inches on the scale, which means that we are finding almost the full value of the 9 inches of the height of the house, then, we found 1 inch because 9-8=1, so if we already found 8, which is a number in the table of 2, we found out 1 so that we can add it with 8 to find the value of 9in on the scale. In this way, after adding, that gives us the value of 9in on the scale!

Answer:

y=28

Step-by-step explanation:

28+7=35

Answer:

a = 4

b = 26

Step-by-step explanation:

median is the middle number(s)

middle numbers are 22 and b

if the median is 24 then

that means the average if 22 and b is 24

so do the math in reverse

22 and b are 2 numbers

24 * 2 = 48
22 + b = 48

48 - 22 = 26

b = 26

mean is average

so do the math in reverse

there are 10 numbers

the average or mean is 19

so all the numbers add up to 190

3+a+10+13+22+26+27+27+28+30 = 190

a + 186 = 190

a = 4
