What is the y-intercept of function g if g(x) = 2f(x) + 1 ?

A. (0,2)
B. (0,-1)
C. (0,3)
D. (0,1)

Answer:

x=15.714

y=5.715

Step-by-step explanation:

Answer:

x=10, y=20

Step-by-step explanation:

okay so to find x, or the way I did it, we just have to look at the top, we know one line is 180 degrees, and we see three angles, 7x,90, and 20

so 90+20+7x=180

and:110+7x=180

therefore: 7x=70

and finally: x=10

To find y also isn't had if we just look at the blue and green lines we see they are intersecting and opposite angles in intersecting lines are congruent meaning they are the same. So we now know that:

5x+2y=90

and we know x=10

so 5x=50

meaning that: 50+2y=90

therefore: 2y=40

and in conclusion y=20

Answer:

I think It is Choice 3 sorry if I am wrong.

Step-by-step explanation:

Answer: 50% increase

Step-by-step explanation:

Think of 20 as 100%

Half of 20 is 10 which is 50% in this scenario.

30-20=10

This means that the price of the item increased by 50% or 10.

Answer: c = [tex]\sqrt{89}[/tex]

8² + 5² = c²

64 + 25 = c²

[tex]\sqrt{89}[/tex] = [tex]\sqrt{c^{2} }[/tex]

[tex]\sqrt{89}[/tex] = c

The length of the third side is 9.4.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Applying Pythagorean theorem.

Third side = x

x² = 8² + 5²

8 x 8 = 64 and 5 x 5 = 25

So,

x² = 64 + 25

x² = 89

x = √89
x = 9.4333

Rounding to the nearest tenth

x = 9.4

Thus,

The length of the third side is 9.4.

Step-by-step explanation:

12 + 11/6x ≤ 5+3x

Subtract 11/6x from each side

12 + 11/6x - 11/6x ≤ 5+3x-11/6x

Subtract 5 from each side

12 + 11/6x - 11/6x -5 ≤ 5+3x-11/6x-5

7 ≤ 3x-11/6x

Get a common denominator

7 ≤ 18/6x-11/6x

7 ≤7/6x

Multiply each side by 6/7

D.   2 ≤ x ≤ 5

Step-by-step explanation:

Notice that there are no points on the graph for x ≤ 2 and x ≥ 5.  Or another way to look at it is that the x's are between 2 and 5, inclusive.

The domain is the set of possible x values.  Therefore,  2 ≤ x ≤ 5 is the set of  values for the domain

Answer:

a=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4a+1−a=19

(4a+−a)+(1)=19 (Combine Like Terms)

3a+1=19

Step 2: Subtract 1 from both sides.

3a+1−1=19−1

3a=18

a=18/3

a=6

Answer:

96

Step-by-step explanation:

100%-60%=40%

40% of x = 64 students (X=Total no. of students)

(40/100)*x=64

x=64*(100/40)

x=160

Missing no. of students=160-64=96

Answer:

96 students

Pls mark me brainliest!

Step-by-step explanation:

If an unknown amount of students is 60% of the students, the 64 of the students must be 40% of the students because 40+60 = 100.

You want to find what 1% equals, so we will divide 64 by 40 because 40% divided by 40 = 1% and whatever you do to one side you do to the other.

64/40 = 1.6

Assuming that the ? number of students that equals 60% will be a whole number, lets go with 1.6.

If 1.6 = 1%, and we want 60%, then multiply both sides by 60, because 1*60 = 60.

1.6*60 = 96

Answer:

x= 1 , y=4

Step-by-step explanation:

x-y= -3 => Equation 1

x+5y= 21 => Equation 2

Substitution Method:

Substitute Equation 1=>

x=y-3 <= Equation 3

Put x=y-3 in Equation 2:

x+5y=21

( y-3)+5y=21

y-3+5y=21

6y-3=21

6y=21+3

6y=24

y=24÷6

y=4

Put y=4 in Equation 1:

x-y= -3

x-4=-3

x=4-3

x=1

Hope this helps :)

Answer:

x = 1

y = 4

Step-by-step explanation:

x - y = -3   then x = y - 3

x + 5y = 21

substitute for x:

y - 3 + 5y = 21

reduce:

6y = 24

y = 4

x = 4 - 3 = 1

check:

1 - 4 = -3

-3 = -3

and

1 + 5(4) = 21

21 = 21

There is nothing in the problem statement that suggests this is a right triangle. Without knowing at least one angle, we cannot solve for a numerical value for the perimeter. The problem title suggests we're to leave the result in polynomial form.
