Solve the system using elimanation: 3x + 5y = -2 and -x + 2y = 8

Answer:

b=6

Step-by-step explanation:

One of the kinds special triangles you learn about are the Pythagorean triples.  These are right triangles with sides in certain ratios. One of them has sides in the ratios 3:4:5.

More generally, this triangle has sides in the ratio 3x:4x:5x

In your triangle, the ratio 8:10 corresponds to 4x:5x with x=2.  Therefore, the remaining side is 3x with x=2, so

b=6

Answer:

answer is 3 11/12

Step-by-step explanation:

1 4/6 =10/6

2 1/4=9/4

when adding fractions that are do not share a common denominatour you have to find a common multiple

which in this case is 12

so 9/4 timesed the top and the bottom by 3 gives you 27/12

and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)

GCF: 3k^2

Answer:

40

Step-by-step explanation:

a^2+b^2=c^2

therefore c^2-b^2=a^2

41x41=1681

9x9=81

1681-81=1600

Sqrt1600=40

The third number is 40

Answer:

for f(3)=2 is y=(2/3)x

Step-by-step explanation:

y=ax

and plug x and y into the parent function.

Answer:

Step-by-step explanation:

f(0) = 6 means y-intercept b = 6

So we have:

                  f(x) = mx + 6     and   f(3) = 2

        So:

                2 = m×3 + 6

                  3m + 6 = 2

                   3m = 2 - 6

                   3m = -4

                    m = -⁴/₃

Therefore the function:

If function  f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.

Degree of polynomial is two so it will have only two solution

f(a)=0 if x=a

or

f(b)=0  if x=b

so put X=x+3

we will get

2[x+3]^2 - 3[x+3] + 4 =  2x^2 +9x +13

so if f(x+3)= 2x^2 +9x +13

The highest degree of a polynomial's monomials with non-zero coefficients is referred to as the polynomial's degree in mathematics. A term's degree is a non-negative integer and is calculated by adding the exponents of all the variables that occur in it.

The highest exponent of a polynomial's variable is referred to as the polynomial's degree. • A polynomial of degree zero is a constant polynomial. Zero polynomial is the name given to the constant polynomial f(x) = 0.

Step-by-step explanation:

i took the quiz and used brainly to check my awnser

for the first question you put the right answer, well done!

for the second question:

the missing side is 14.1 ft.

c²= a²+b²

16.7² = x² +8.9²

278.89= x²+79.21

x²=278.89-79.21= 199.68

we want to find x not x² so we square root x² and that gives us the value for x

x=Square root of 199.68

x= 14.1 ft

Answer:

slope = -1/4, y-intercept = 50

Step-by-step explanation:

x=0 y=50

x=100 y= 25

y= mx+b

b= 50

25= 100 m +50

100m = - 25

m= -1/4

where m is the slope and b is the y intercept

Answer:

its choice 3) 5

Step-by-step explanation:

We want to see which of the given values of x is not in the domain of f(x) = log(10 - 2x).

The correct option is (3); x = 5.

The domain is defined as the possible inputs of a given function f(x), in this particular case, we have:

f(x) = log(10 - 2x).

Remember that the logarithmic function is only defined for positive arguments, so the values of x that are NOT in the domain of f(x), are these x values such that:

10 - 2x ≤ 0

Solving it for x we have:

10 ≤ 2x

10/2 ≤ x

5 ≤ x

So any value of x equal to or larger than 5 is not in the domain of the given functions, and of the shown options, the only one that is equal or larger than 5 is x = 5, the third option.

So the correct option is the option (3).

then

2x + y = 10

2 * 5 + y = 10

y = 10 - 10

y = 0

x = 5, y = 0

Answer:

x=5

Step-by-step explanation:

so it would be 2(5) since 5 is x and that would be 10+y=10.

soo if you're trying to find what + what = 10 it would be zero.

10+0=10.

Answer: c=8

Step-by-step explanation: All three angles in a triangle add up to 180 degrees so 9c+66+42=180. First add 66 and 42 which is 108, so now you have 9c+108=180. Then subtract 108 from both sides to get 9c=72. Finally, divide each side by 9 to isolate c and you get c=8

3 horses and 4 ducks

Step-by-step explanation:

let h be the no. of horses and d be the no. of ducks

h+d=7

d=7-h

Since horses have 4 legs and ducks have 2 legs,

4h+2d=20

4h+2(7-h)=20

4h+14-2h=20

2h=6

h=3
