Sliva [168]3 years ago

Answer:

5

Step-by-step explanation:

To evaluate f(x)=-2x^2+2x+4 at x=1, we must replace the x with 1

f(1)=-1(1)^2+2(1)+4\\f(1)=-1(1)+2+4\\f(1)=-1+6\\f(1)=5

Answer:

y = -x-3

x-y = -3

x - 2y = 10

Step-by-step explanation:

x − 3y = 6

Slope intercept form is y = mx +b

We need to solve for y

Subtract x from each side

x-x-3y = -x+6

-3y = -x +6

Divide each side by -3

-3y/-3 = -x/-3 +6/-3

y = 1/3 x -2

Standard form is Ax +By = C

y = -x-3

Add x to each side

x-y = -x+x-3

x-y = -3

y = 1/2x -5

We do not like fractions in standard form, so multiply by 2

2y = 2*1/2x -2*5

2y =x-10

Subtract x from each side

-x +2y = x-x-10

-x+2y = -10

We like to have the coefficient on x be positive

Multiply by -1

x - 2y = 10

Two-digit natural numbers are formed, with replacement, from the digits 0 through 9.
alexdok [17]

Answer:

The first digit of a two digit number can be any of digits 1 - 9. It cannot be 0 though. Therefore there are 9 possible digits for the first place.

There are 5 possible digits for the second position. The two digit number has to be odd and therefore the final digit must be 1,3,5,7 or 9

Therefore for each and every one of the nine first digits there are 5 digits that the second can be.

Therefore ANSWER = 9 * 5 = 45 possible permutations.

2. The largest two digit number = 99

Subtract 57 and you get 42

ANSWER = 42

The forty two numbers are 58 ,59, 60, 61......98, 99

Solve for x <br> solve for x <br> solve for x
goldenfox [79]

Answer:

x = 95

Step-by-step explanation:

(2x - 60)° = (x + 35)° (corresponding angles are congruent)

2x - 60 = x + 35

2x - 60 - x = x + 35 - x

x - 60 = 35

x - 60 + 60 = 35 + 60

x = 95

First: Find out how many of Jolie's balls are blue.

300 * 35% = 300 * 0.35 = 105 blue balls.

Second: Find the difference between the total number of balls and the blue balls to find out how many green balls Jolie has.

300 - 105 = 195 green balls.
