Answer:
y = -3/8(x - 4)² + 7 or y = -3/8x² + 6x + 1Step-by-step explanation:
We can see on the graph that the vertex is (4, 7) and the leading coefficient is negative as parabola opens down.
The vertex form is:
y = a(x - h)² + k, substitute coordinates to get,y = a(x - 4)² + 7Considering the y-intercept is (0, 1), substitute values to find the value of a:
1 = a(0 - 4)² + 7a(4²) = 1 - 716a = -6a = -6/16a = -8/3The function is:
y = -3/8(x - 4)² + 7In standard form:
y = -3/8(x² - 16x + 16) + 7 = -3/8x² + 6x - 6 + 7 = -3/8x² + 6x + 1what is 500000 x 500000

-4 ≥ k - 2
Solve the inequality
Answer:
-2 ≥ k
Step-by-step explanation:
First you have to use inverse operation and add 2 on both sides. You should get -2 ≥ k as your answer.
Answer:
k ≤ -2
Step-by-step explanation:
move -4
you will get -2
move k
k ≤ -2
The ratio of yellow sweets to purple sweets is 5:4.
Alice eats 3 purple sweets and the ratio is now 5:3.
Work out how many sweets there were at the beginning.
Answer:
27
Step-by-step explanation:
The ratio of yellow : purple = 5 : 4 = 5x : 4x ( x is a multiplier )
After Alice eats 3 purple sweets, then ratio is
5 : 3 = 5x : 4x - 3
Express the ratio in fractional form, that is
[tex]\frac{5}{3}[/tex] = [tex]\frac{5x}{4x-3}[/tex] ( cross- multiply )
5(4x - 3) = 15x
20x - 15 = 15x ( subtract 15x from both sides )
5x - 15 = 0 ( add 15 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Then
number of sweets at beginning = 5x + 4x = 9x = 9(3) = 27

A cuboid is 12 cm broad and 10 cm high. If its volume is 1800 cm³, find its length.
Answer:
it's length is 15cm
Step-by-step explanation:
let a represent the length
a × 10 ×12 = 1800
a×120= 1800
a = 1800÷12
a=15cm
1800=L×h×b
1800=L×10×12
1800=120L
L=1800/120
L=15cm ans..

Find the x- and y-intercepts of the graph of x– 10y = 31. State your answers as
whole numbers or as improper fractions in simplest form.
Answer:
x -intercept (31,0)
y-intercept (0,-31/10)
Step-by-step explanation:
x-10y=31
x-10(0)=31
x=31
x-10y=31
0-10y=31
-10y=31
y=-31/10
The perimeter of a rectangle is 54 cm. The width is 1 cm shorter than the length. What is the length and width of the rectangle
Answer:
13 is the width and 14 is the length
Step-by-step explanation:
I divided 54 and got 13.5 then I started adding random numbers around 13 like 12+12+13+13 that didn't work it came out to 50 so I went up and did 13+13+14+14 and got my answer
PLEASE HELP- A triangle has vertices A(0, 0), B (9, 4), and C(–2, 10). What are the coordinates of the triangle after a dilation with a scale factor of 1/2 ?
Basically multiply the x and y coordinates of each point by 1/2
For example, I'll do C which is ( -2 , 10 )
-2 * 1/2 = -1 and 1/2 * 10 = 5
The new coordinate is ( -1 , 5 )
Now you can try the other points

Write the slope intercept equation for line AB
Answer:
Y = 2
Step-by-step explanation:
The answer choices are in slope intercept form which is Y=mx+b. Since the slope is 0, there is no need for "mx" in the equation, so y= 2 where b is 2

Mr. phill stopped to fill his car with gas on the way to New York. It took 1 ¼ minutes to fill a 15 liters of gas in his tank. At this rate, how long will it take to fill his 50 liter gas tank?
Answer:
4 1/6 min or 4 min 10 secStep-by-step explanation:
Filling rate is:
15 ÷ 1 1/4 = 15 ÷ 5/4 = 15 × 4/5 = 12 l/minTotal volume is 50 l, time required to fill is:
50/12 = 4 2/12 = 4 1/6 min or 4 min 10 secLine p passes through point (0,8) and is perpendicular to the graph of y=1/4x+2 line q parallel to line p and passes through point (-3,6) which is the equation of line q in slope intercept form

Formula of area
AREA = LENGTH (multiply) BREATH
Answer:
The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.
In this case, 4 is the base, and 7 is the height.
So we have: Area = 1/2(4)(7)
Simplifying: Area = 2(7), Area = 14.
The area of the triangle is 14 meters squared.

Find the exact value of z.
a² + b² = c²
First find out the length of the line in the middle. We know that a² + 16² = 27², which means a = √473
Now write out all the equations for all the right triangles in the diagram.
Let the side of the base of the triangle be x and the remaining sides of z be y.
x² + 27² = (16+ y)²
y² + (√473)² = x²
From here solve and find y. Once you get y, y + 16 is your z, the answer.

15. Two angles are supplementary. One
angle is 8 times larger than the other.
Find the measure of the two angles.
Answer:
82 and 98 degrees.
Step-by-step
Supplementary angles are equal to 180 degrees. Let's assume both are 90 degrees for both angles. You would then do the following:
90-8= (for angle 1)
90+8= (for angle 2)
Getting 82 and 98 degrees.
bus driver drove from Philadelphia to Washington D.C. He drove the first 100 km in 2 hours, the next 55 km in 1 hour, and the final 75 km in 2 hours. What is the average speed of the bus throughout the trip?
Answer: I think it’s 46
Step-by-step explanation: Because you add up the miles he drove them divide them by how long he drove
Ex 55+75+100=230 then you divide that by 5 hours = 46 per hour
