Answer:
mid point formula is :
and B (-1,-5) is the mid point of AC.
Assuming that x2 and y2 are coordinates of C, so x2 = 4 and y2 = -1
and again,
coordinates of A (-6,-9)
Answer:
20x⁵ + 20x⁴
Step-by-step explanation:
Use distributive rule: a*(b +c) =a*b + a*c
5x⁴(4x + 5) = 5x⁴ * 4x + 5x⁴ * 5
= 20x⁵ + 20x⁴
Hint: 5x⁴ * 4x multiply the coefficient and then the variables. For multiplying variable, if they two have same base, then add the powers
5*4 * x⁴ * x = 20x⁵
Answer: 32.54
Step-by-step explanation:
Change 5% into a decimal --> .05 then
multiply by the price 30.99 times .05 is 1.5495 then
take 1.5495 and add 30.99 = 32.5395
Round decimal total --> 32.54
Answer:
$4 and $3
Step-by-step explanation:
First, write out the equations as 70x + 29y = 367 and 70x + 45y = 415. Solve by using the elimination method by subtracting 70x from 70x. 45y minus 29y is equal to 16y. 415 minus 367 is 48. Divide 48 by 16, to get y is equal to get y is equal to three. Y represents pepperoni pizzas, so a pepperoni pizza costs $3. Plug a 3 into any equation for y and solve for x. 29 times 3 is 87. 367 minus 87 is 280. 280 divided by 70 is equal to 4, so x is equal to 4.
Answer:
2x+3x-15=180°
Step-by-step explanation:
When two angles are supplementary, their angles would equal to 180° total when added together. In this answer, the two angles are added together to create 180°.
