Answer 2

Answer:

(0,-5)

(0,0.50)

Step-by-step explanation:

just put the number that doesn't have x with it in the answer spot but don't forget to do the (0,#) it's important that you do it like that so for example the problem y=4x-3 you would just put in the answer column (0,-3)

If using the method of completing the square to solve the quadratic equation x^2-5x-19=0x, which number would have to be added to "complete the square"?

Answers

Answer:

25/4 or 6.25

Step-by-step explanation:

Given that the general equation of  a quadratic equation is given as

ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.

Hence given x^2-5x-19=0, to complete the square, we add

(-5/2)^2 to both sides following the illustration given.

This is 25/4 or 6.24

The solution of (10 x/6)(10 x/8) = 1010 is

Answers

The solution to the exponential expression is given as follows:

x = 34.29.

How to solve the exponential expression?


The exponential expression for this problem is defined as follows:

[tex]10^{\frac{x}{6}} \times 10^{\frac{x}{8}} = 10^{10}[/tex]

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents.

The sum of the exponents is given as follows:

x/6 + x/8 = 4x/24 + 3x/24 = 7x/24.

Hence the equivalent expression is given as follows:

[tex]10^{\frac{7x}{24}} = 10^{10}[/tex]

The function 10^x is an injective function, hence the value of x is obtained as follows:

7x/24 = 10

7x = 240

x = 240/7

x = 34.29.

Which function is quadratic?
A {=5.3), (-2.0), (1, 3). (4. 6))
B {(-2, 12), (0.2), (2.-8). (4, -18)}
C {(0, -126), (4, -14), (8, 2).(12,18)
D {(0, -10), (1.-7), (2, 2), (3. 17)}

Answers

Answer:

step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)

step 2. so the question becomes is C a quadratic

step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4

step 4. write out the y values: -126, -14, 2, 18

step 5. write out the differences: 140, 16, 16

step 6. write out the differences: -124, 0.

step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't

step 8. C is not a quadratic.

b.The y-intercept of g(x) is greater than the y-intercept of f(x)
c.The y-coordinate of the vertex of f(x) s greater than the y-coordinate of the vertex of g(x)
d.The x-coordinate of the vertex of g(x) is greater than the x-coordinate of the vertex of f(x)

Answers

Answer:

a. the y-intercept of f(x) is greater than the y-intercept of g(x)

Step-by-step explanation:

Given function:

f(x)=(x - 4)^2 - 4

We can work out the function from the table values:

g(x) = (x + 2)^2 - 4

Options:

a. the y-intercept of f(x) is greater than the y-intercept of g(x)

True. x= 0 ⇒ f(0) = (-4)^2 - 4 = 12, g(0) = 2^2 - 4 = 0

b. The y-intercept of g(x) is greater than the y-intercept of f(x)

False. See previous option.  

c. The y-coordinate of the vertex of f(x) s greater than the y-coordinate of the vertex of g(x)

False. They are same = -4

d. The x-coordinate of the vertex of g(x) is greater than the x-coordinate of the vertex of f(x)

False. -2 vs 4

Answer:

We conclude that the 12x is the required expression that is equivalent to 7x + 4x + x and has only one term.

Step-by-step explanation:

Given the expression

[tex]7x+4x+x[/tex]

The current expression has three terms such as 7x, 4x, and x.

The current expression can be further simplified such as

[tex]7x+4x+x[/tex]

Add similar elements:  [tex]7x+4x+x=12x[/tex]

[tex]=12x[/tex]

Thus, the given expression [tex]7x+4x+x[/tex] can be expressed as the only one term such as [tex]12x[/tex].

i.e. [tex]7x+4x+x=12x[/tex]

Therefore, we conclude that the 12x is the required expression that is equivalent to 7x + 4x + x and has only one term.

Jane worked 38 hours at the grocery store last week and made $296.40. If she works three less hours this week than she did last week, how much will she still make?

Answers

Answer:

$273

Step-by-step explanation:

Given data

Jane worked 38 hours at the grocery store last week and made $296.40

she worked 3 hour less= 38-3= 35 hours

Hence if in 38 hours she made   $296.40

              in 35 hours she will make x

cross multiply

x= 35*296.40/38

x= 10374/38

x=$273

In triangle ABC, the measure of angle ABC is 51°
and ACB is a right angle. What is the measure of
angle BAC in degrees?

Answers

Answer:

39 degrees

Step-by-step explanation:

The sum of angle in the triangle ABC is a80 degrees

m<ACB + <BAC + <ABC =1 80

90 + <BAC + 51 = 180

141 + m<BAC = 180

m<BAC = 180-141

m<BAC = 39 degrees

Hence the measure of m<BAC is 39 degrees
