Step-by-step explanation:

Answer:

a = −1 or a = 7

Step-by-step explanation:

Let's solve your equation step-by-step.

( a − 7 ) ( a + 1 ) = 0

Step 1: Simplify both sides of the equation.

a^2 − 6a − 7 = 0

Step 2: Factor left side of equation.

( a + 1 ) ( a − 7 ) = 0

Step 3: Set factors equal to 0.

a + 1 = 0 or a − 7 = 0

a = −1 or a = 7

Answer:

  a: 0; b: 1; c: 1; d: ∞; e: 0; f: ∞

Step-by-step explanation:

Simplify the expressions to put the left and right in the same form. Then compare. If the x-coefficients are the same, there will be 0 or ∞ solutions. If they are different, there will be 1 solution.

If the x-coefficients are the same, look at the constants. If they are different, there will be 0 solutions. If they are the same, there will be ∞ solutions.

Is 5 a solution for the inequality x > -6?


Answers

Answer:

yes

Step-by-step explanation:

Given

x > - 6

That is if x is greater than - 6 then it is a solution

x ∈ { - 5, - 4, - 3, - 2, - 1, 0, 1, 2, 3, 4, 5, .... } ← are all valid solutions

Thus 5 is a solution to x > - 6

Angela baked 5 batches of lemon sugar cookies with 17.5 cups of flour. She also made 3 batches of vanilla cookies using 11.25 cups of flour. Which type of cookies required more flour per batch?

Answers

vanilla cookies require more flour per batch

vanilla cookies = 3.75 cups of flour per batch
lemon sugar cookies = 3.5 cups of flour per batch

explanation:

lemon sugar cookies -
divide # of cups by the # of batches
17.5/5= 3.5

vanilla cookies -
divide # of cups by the # of batches
11.25/3= 3.75

to double check:
multiply 3.75 by 5 and you will see 5 batches of vanilla cookies will use 18.75 cups
and 5 batches of lemon cookies takes 17.5 cups

The slope is 1 or -1 depending on if the line is going down or if it’s going up.

To find the slope count how many units up from the starting point to the end point which is 14. Then divide that number by how many units horizontally from the starting point to the end point which is 14. 14/14=1.
In this case (taking that each block is 1) you can see that the line is y=x +1.

X is 38
hope it helped

Answer:

x = 38°

Step-by-step explanation:

this is a four-sided polygon, so the sum of the interior angles measures 360 degrees; formula is (n - 2) · 180 where 'n' is the number of sides

add all four expressions and set equal to 360

5x - 33 + 5x + 13 = 360

10x - 20 = 360

10x = 380

x = 38

check by plugging 38 into each expression to make sure the total is 360

starting in upper left and moving clockwise, the angles are: 75°, 82°, 114°, 89°
