hector solves 9 x 8 by subtracting 1/8 from 10/8

Answer:

I think your answer is 48cm

Step-by-step explanation:

Answer:

-9

Step-by-step explanation:

I believe that he is not correct. By him saying a number hes saying 10-5=5 but you could also do 10-0=10 so he is not correct.

Yes. Jim is correct. because a number he saying is 10-5=5 but it could also be 10-0=10.

An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.

We have given that Jim stated, "When you subtract a number from 10, the answer will always be less than 10"

let's consider an example and say 2 is the number.

If we subtract 2 from ten, then we get 8 which is less than 10.

Therefore, if the number is greater than ten it would result in a number which less than ten

Due to this it would result in a negative number.

Hence Yes. Jim is correct. because a number he saying is 10-5=5 but it could also be 10-0=10.

Answer:

The point (0, 1) represents the y-intercept.

Hence, the y-intercept (0, 1) is on the same line.

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where

Given

Using the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case:

substituting the values m = 2/3 and the point (-6, -3)  in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-3\right)=\frac{2}{3}\left(x-\left(-6\right)\right)[/tex]

[tex]y+3=\frac{2}{3}\left(x+6\right)[/tex]

Subtract 3 from both sides

[tex]y+3-3=\frac{2}{3}\left(x+6\right)-3[/tex]

[tex]y=\frac{2}{3}x+4-3[/tex]

[tex]y=\frac{2}{3}x+1[/tex]

comparing with the slope-intercept form y=mx+b

Here the slope = m = 2/3

Y-intercept b = 1

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

Given the line

[tex]y=\frac{2}{3}x+1[/tex]

at x = 0, y = 1

Thus, the point (0, 1) represents the y-intercept.

Hence, the y-intercept (0, 1) is on the same line.

The given polygons are not similar.

Given are two polygons which are similar.

For the polygons to be similar, we can write -

AB/PQ = BC/QR = CD/RS = DE/ST = AE/PT

4/8 = 3/6 = 7/15 = 10/10 = 5/10

1/2 = 1/2 ≠ 7/15 ≠ 1 ≠ 1/2

Therefore, the given polygons are not similar.

Answer:

x = -8 + √114 ≈ 2.7 [nearest tenth]

y = 7

Step-by-step explanation:

Given that ∆CAB ≅ ∆CDB, you can use CPCTC [corresponding parts of congruent triangles are congruent] to evaluate the given lengths and angle measures, to show that the corresponding measures are the same for both triangles. Using the triangle sum theorem which states that all angles in a triangle must add up to 180°, you can find ∠ACB.

If ∠CAB = 70°, and ∠ABC = 60°,

∠ACB = 50° because ∠CAB + ∠ABC + ∠ACB = 180°.

∠CAB + ∠ABC + ∠ACB = 180° →

∠ACB = 180° – ∠CAB – ∠ABC

∠ACB = 180° – 70° – 60°

∠ACB = 50°

70° + 60° + 50° = 180°.

Remember, the order of the letters in the angle are very important because it corresponds to the parts of the angle that make up the vertex which is the middle letter, along with the first and last letters which are the endpoints.

Because ∆CAB ≅ ∆CDB,

∠ACB ≅ ∠DCB [CPCTC].

As indicated in the problem, ∠DCB = (x² + 16x)°.

Because ∠DCB ≅ ∠ACB = 50°,

(x² + 16x)° = 50°.

So this can be completed as a square by converting this into vertex form.

x² + 16x = (x + 8)² – 64.

Then, (x + 8)² – 64 = 50.

(x + 8)² – 64 + 64 = 50 + 64 →

(x + 8)² = 114 →

(x + 8) = ±√114 →

x = -8 ± √114 [one more step]

[The measure must be positive so the expression must be added]

x = -8 + √114.
