Answer:
Down
Step-by-step explanation:
The formula for quadratic equations is [tex]f(x)=a(x-h)^{2}+k[/tex]. In this k controls the y-values, and therefore controls the vertical shifts. If k is negative then the quadratic will shift down. Since k is -7 in this equation it will shift down.
solve graphically please send me by solving and clicking photo plzzzz
Answer:
Subtract 5x from both sides of the equation.
7y=1−5x
x+4y=−5
Divide each term by 7 and simplify.
y=17−5x/7
x+4y=−5
Subtract x from both sides of the equation.
y=1/7−5x/7
4y=−5−x
y=1/7−5x/7
Divide each term by 4 and simplify.
y=1/7−5x/7
y=−5/4−x/4
y=1/7−5x/7

Guys please help me I’ll give u 7 points and mark brainliest need asap
Answer:
a. y = 3x + 4.5 & y = 7x + 2
b. x = 0.625 (year)
c. 6.375 feet
Explanation:
Type A starts at 4.5 and Type B starts at 2 ,each year can be marked as x
type A grow 3 inches per year = 3x
type B grows 7 inches per year = 7x
y = the total height
Since they both equal to y, you can set them equal to each other
3x + 4.5 = 7x +2
After solve you get answer for b
Work: 3x + 4.5 = 7x + 2
4.5 = 4x + 2
2.5 = 4x
0.625 = x
Substitute the value of x you got from part b into each equation then you will get 6.375 as your y value which is also your height

A trapezoid with an area of 36 inches squared.
What is the area of the enlarged trapezoid?
54 in.²
81 in.²
576 in.²
864 in.²
Answer:
B. 81 in.²
Step-by-step explanation:
We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5. We are asked to find the area of the enlarged trapezoid.
The area of the original trapezoid is 36 square inches.
Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.
The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.
1.5 × 1.5 = 2.25
Area of new trapezoid: 2.25 × 36 in²
Area of new trapezoid = 81 in²
The area of the enlarged trapezoid would be 81 in² or option B.

PLS HELP!!! TIMED!!!! I need a step by step explanation of how to divide 93726 by 4!!!!
Answer: the answer is 23434
Step-by-step explanation:first divide 4 by 9 which goes only once, then you would then have 13 which would go only 3 times so 12 minus 13 which is 1 and then goes with 7 to make 17 which means it goes in only 4 times which is 16 meaning the answer is 1 again and then goes with 3 to make 13 and 4 goes in 3 times with 13 to make 12 and then you get 1 which goes into 6 to make 16 and then 4 goes into 16 4 times and then you would get an answer of 23434
The subtotal of your computer purchase was $398.50. If the sales tax rate is 7.25%, how much will you pay in tax for the computer?
I will Mark Brainliest
The answer is NOT 54.97
Don't forget to convert the percent into a decimal.
Answer:
Amount of tax = 26.93 (Approx.)
Step-by-step explanation:
Given:
Cost of computer = $398.50
Sales tax rate = 7.25% = 0.0725
Find:
Amount of tax
Computation:
Amount of tax = [Cost of computer x Sales tax rate] / [1+Sales tax rate]
Amount of tax = [398.50 x 0.0725] / [1+0.0725]
Amount of tax = 26.93 (Approx.)
Which number best represents a depth of seven hundred and five-tenths meters below the ground?
Answer:
-700½ meters or -700.5 meters
Step-by-step explanation:
Usually, the depths below the ground are denoted by the minus sign.
Seven hundred and five-tenths meters mean 700+(5/10) which is equal to 700+1/2. So, the answer becomes -700½ meters or -700.5 meters.

A stack of one dozen cookies of diameter
5 in. exactly fits in a cylindrical container of
volume 179.715 in.3. Which is the thickness of
each cookie?
Answer:
.763 in for each cookie
Step-by-step explanation:
[tex]179.715 =\pi (2.5)^{2} h\\179.715= \pi (6.25)h\\179.715=19.635h\\h=9.153\\[/tex]
After you solve for the height you would divide it by 12 to get the thickness of one cookie which is .763 in.

Step-by-step explanation:
Equation A is true among the given equations.
What is a matrix?A matrix is an array of values arranged in rows and columns, such that they are used to represent a mathematical object.
Matrices are associative when they are multiplied. This means that any two adjacent matrices can be multiplied first and then the third one can be multiplied. This would yield the same answer. This means that equation A is true. In equation B, different matrices are multiplied and added. Therefore, the LHS is not equal to the RHS. In equation C, the order in which the matrices are written and multiplied is different. Matrices aren't commutative with multiplication. Therefore, the LHS is not equal to the RHS. Similarly, equation D is also wrong.Thus, we have found that among the given equations, equation A is true.

Find the tangent of angle U.
A) 48/55
B) 48/73
C) 55/48
D) 55/73
Answer:
C. 55/48
Step-by-step explanation:
perpendicular (p) = 55
base (b) = 48
Tangent < U = p /b = 55 /48
In triangle TUV, the tangent of angle U would be tan U = 55/58. Hence option C is true.
Used the formula of the tangent of an angle that states,
Tan θ = Opposite / Base
Given that,
A triangle TUV is shown in the image.
Now by definition of the tangent of an angle,
tan U = TV/UV
Substitute TV = 55 , UV = 48;
tan U = 55/58
Therefore, Option C is true.
