brainliest please

i calculated it

Answer:

No, Isiah is not correct. The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial. 5b4 is a factor of -25a2b5 and -35b4, but not a3. Additionally, a2 is a factor of a3 and -25a2b5, but not -35b4.

Step-by-step explanation:

the linear equation would be y = -2x-3

Answer:

D. 3/2, -9

Step-by-step explanation:

First, rearrange the equation 3x - 2y = 18 into the slope-intercept form of y = mx + b:

3x - 2y = 18

2y = 3x - 18

y = 3x/2 - 9

from this, u can tell that the slope is 3/2 and the y-intercept is -9 (option D)

hope this helps!

Answer: 225 meters per second

Step-by-step explanation:

Bruno was able to reach 450 meters in just 2 minutes.

His velocity therefore, can be determined by the speed formula which is:

= Distance / Time

= 450 / 2

= 225 meters per second

= 225 m/s

His velocity is 225 m/s.

Answer: Option 1 & Option 4

Step-by-step explanation:

The triangle is scalene because it doesn't have a right angle (can't be right)

Doesn't have 2 congruent angles (can't be isosceles)

The triangle is also obtuse because it has an angle that is greater than 90°

It would mean the world to me if you could mark me brainliest!

Given:

The functions are:

(1) [tex]h(x)=\sqrt{1-x}[/tex]

(2) [tex]x+y=4[/tex]

(3) [tex]x^2+y^2=16[/tex]

To find:

The domain of given functions.

Solution:

Domain is the set of input and x -values.

Value under the square root must be positive because if the number under square root is negative, then it is a complex or imaginary number.

(1) [tex]h(x)=\sqrt{1-x}[/tex]

The function is defined if

[tex]1-x\geq 0[/tex]

[tex]1\geq x[/tex]

The function is defined for all real values of x which are less than or equal to 1.

Therefore, the domain of the function is (-∞,1].

(2) [tex]x+y=4[/tex]

It is a linear function and linear function is defined for all real values of x.

Therefore, the domain of the function is (-∞,∞).

(3) [tex]x^2+y^2=16[/tex]

It can be written as

[tex]y^2=16-x^2[/tex]

[tex]y=\pm \sqrt{16-x^2}[/tex]

It is defined if

[tex]16-x^2\geq 0[/tex]

[tex]16\geq x^2[/tex]

[tex]4\geq x\geq -4[/tex]

This function defined for all real values of x from -4 to 4.

Therefore, the domain of the function is [-4,4].

Answer and Step-by-step explanation:

Distribute the 1p to the y and -6 and distribute the 2 to the 3y and 6.

10y - 50 + 6y + 12

Now, combine like terms.

16y - 38

Answer:

3/20

Step-by-step explanation:

Given that :

Share for 5 persons = 3/4 of a whole pizza

Each person gets an equal size of the share :

Hence, share per person :

Portion of pizza / number of persons

3/4 ÷ 5

3/4 * 1/5

= (3*1) / (4*5)

= 3/20

Answer:

it is going to remain 3 1/2

Step-by-step explanation:

The absolute doesn't change anything since the term inside it is positive.

however if you were given | -3 1/2|, then in that case you would change the negative sign and make it positive.

Answer:

Pretty sure it's 6.4 lbs

Step-by-step explanation:

We have to set up a proporion. So ?/40 and 16/100 because 16% of 100. Since we can't cross multiply 100 and ?, we have to cross multiply 16 × 40 = 640. We have 100 leftover, so 640÷100=6.4

Answer:

(1)=100

Step-by-step explanation:

5.2 divided by 10= 0.52 then divide by 10 = 0.052

so instead do 5.2 divided by 100=0.052

Answer: 100

Step-by-step explanation:

Since you change the decimal place two times to the right, you divide it by 100.

Given:

The figure of a right angle triangle.

To find:

The measure of side AB.

Solution:

In a right angle triangle,

[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]

In the given triangle,

[tex]\cos B=\dfrac{BC}{AB}[/tex]

[tex]\cos (20^\circ)=\dfrac{7}{AB}[/tex]

[tex]\cos (20^\circ)AB=7[/tex]

[tex]AB=\dfrac{7}{\cos (20^\circ)}[/tex]

On further simplification, we get

[tex]AB=\dfrac{7}{0.93969}[/tex]

[tex]AB=7.449265[/tex]

[tex]AB\approx 7.45[/tex]

Therefore, the measure of AB is 7.45 units.
