When GH=7z-1 and CB=4z-3 what is GA?

Answer:

Vertex: (2,-2)

Axis of symmetry: x=2

Step-by-step explanation:

The vertex is the maximum or minimum point of a quadratic, which we can see on the graph is (2,-2).

The axis of symmetry is the line about which the graph of the parabola is symmetric, which is the line x=2.

Answer:

(-1.5, 1.5), '(-1.5, 1) and (0.5, -1)

Step-by-step explanation:

Given the coordinate (x, y) If dilated by a factor k, the resulting coordinate will be (kx, ky).

Similarly given the coordinates of a triangle  (−3, 3), (−3, 2), and (1, −2)

when dilated by a factor of 1/2, the new coordinates will be at;

A (-3, 3) = A'(1/2*-3, 1/2 * 3) = A'(-1.5, 1.5)

B (-3, 2) = B'(1/2*-3, 1/2 * 2) = B'(-1.5, 1)

C (1, -2) = C'(1/2*1, 1/2 * -2) = C'(0.5, -1)

Answer:

28 hrs

Step-by-step explanation:

in 8 hrs she earns $320,

so in 1 hr she earns $320/8=$40

no. of hrs she takes to earn $1120 is,

=1120/40= 28 hrs

Annie would need to work 28 hours to earn $1,120 at the same rate.

To determine how long Annie would have to work to earn $1,120 at the same rate, we can set up a proportion based on the given information.

Let's define:

x = the number of hours Annie needs to work to earn $1,120.

According to the information given, Annie earns $320 for 8 hours of work. This can be expressed as the rate: $320/8 hours.

We can set up the proportion as follows:

320/8 = 1120/x

To solve this proportion, we can cross-multiply and then solve for x:

320x = 8 * 1120

320x = 8960

Dividing both sides of the equation by 320:

x = 8960/320

x = 28

Therefore, Annie would need to work 28 hours to earn $1,120 at the same rate.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the age of a man = x

Age of his brother = y

Three yrs hence, a man will be three time his brother age

This is written as:

x + 3 = 3(y + 3)

x + 3 = 3y + 9 .... Equation 1

The sum of present age is 18

= x + y = 18

x = 18 - y

We substitute 18 - y for x in Equation 1

find their present age

18 - y + 3 = 3y + 9

Collect like terms

21 - 9 = 3y + y

12 = 4y

y = 12/4

y = 3 years

x = 18 - y

x = 18 - 3

x = 15 years

Answer:

first option

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = - 2 and (a, b ) = (4, - 4 ) , then

y - (- 4) = - 2(x - 4) , that is

y + 4 = - 2(x - 4)

Answer:

4,600

Step-by-step explanation:

First you find 2% of 5,000 which is 100 then you determine 2% every 4 years which is 100x4 which equals 400. then subtract 400 from 5,000 which gets you 4,600

Answer:

4600

Step-by-step explanation:

2% of 5000 is 100

100 x 4 = 400

5000 - 400 = 4600

Answer:how many terms are there? 4

whats the coefficient of the 3rd term? -2

what is the constant? 12

Step-by-step explanation:

12, 2x^3, -2x, and -5x^2 are each one term, adding up to 4 terms

the third term is -2x, with -2 as the coefficient and x as the variable

lastly, the constant is a value in an equation with no x, in this case it’s 12
