Opens up or down, Vertex: (-10, -1), Passes through: (-8, -5)
Answer:
opens down
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) - (- 10, - 1 ) , then
y = a(x + 10)² - 1
To find a substitute (- 8, - 5) into the equation
- 5 = a(- 8 + 10)² - 1 ( add 1 to both sides )
- 4 = a(2)² = 4a ( divide both sides by 4 )
- 1 = a
y = - (x - 10)² - 1 ← equation in vertex form
To determine if it opens up/ down consider the value of a
• If a > 0 then curve opens up
• If a < 0 then curve opens down
Here a = - 1 < 0 then curve opens down

The measure of angle PST 129 degrees after applying the properties of the triangle.
What is the triangle?In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is given that:
The triangle is shown in the picture.
The equation can be made:
5x - 9 = (180 - (11x - 3))
5x + 11x = 180 + 3 + 9
16x = 192
x = 192/16 = 12
The measure of angle PST = 11x - 3
= 11(12) - 3
= 129 degrees
Thus, the measure of angle PST is 129 degrees after applying the properties of the triangle.

9514 1404 393
Answer:
x can be any value (infinite number of solutions)
Step-by-step explanation:
The equation simplifies to ...
2(x -2) +3 = 2x -1
2x -4 +3 = 2x -1
2x -1 = 2x -1
This is true for every value of x. There are an infinite number of solutions.

Ms.Maxwell bought a purse with 1/4 of her money. The purse cost $37.00. How much money did Ms.Maxwell have left after she bought the purse?
Answer:
the money left after purchasing the purse is $111
Step-by-step explanation:
The computation of the money left after purchasing the purse is given below:
Since in the question it is mentioned that she bought a purchase with one-fourth of money
And, the purse cost is $37
So the amount left would be
= $37 × (3 ÷ 4) ÷ (1 ÷ 4)
= $37 × 0.75 ÷ 0.25
= $111
Hence, the money left after purchasing the purse is $111

Use the Law of Cosines to solve for the side BC. Round your answer to the point
nearest whole number. Write the value only *
Answer:
BC = 50
Step-by-step explanation:
Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cosy (c is BC)
c^2 = 30^2 + 21^2 - 2(30)(21)cos123
c^2 = 900 + 441 - 1260*(-0.888)
c^2 = 1341 - (-1118.841)
c^2 = 2459.841
c = 49.597
c = 50

Answer:
4) 2/6 or 1/3
5) 42/110 or 21/55
Step-by-step explanation:
4) there are two red options out of a total of 6 options, so 2/6
5) 7 red out of total of 11, so 7/11 · 6/10 = 42/110
To get the fraction 6/10:
we reduce 7 to 6 because there is one less red than originally
we reduce 11 to 10 because there is one less from the initial total

A taxi charges a flat fee of $3.00, plus an additional $1.25 per mile. Antonio can spend no more than $18. Choose the inequality that represents the number of miles he can ride, an describes the solution set.
Answer: 1.25m + 3 ≤ 18; Antonio can ride 12 or fewer miles
Step-by-step explanation: so you can break down the answer choices and only have a and b left because no more than means this sign: ≤
and 1.25 is the cost for each mile so your multiplying m and 1.25 and then you add that with 3.
