Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression r

Alex_Xolod [135]

Answer:

Gross pay per days is 5h+8 dollars

Step-by-step explanation:

we are given

total gross pay =35h+56 dollars

total number of days =7

we know that

gross pay per day = ( total gross pay)/(total number of days)

we can plug values

gross pay per day is

$=\frac{35h+56}{7}$

we can simplify it

$=\frac{7(5h+8)}{7}$

$=5h+8$

Answer: $y^4$ + $\frac{-73}{35}y^2$ - $2$

Step-by-step explanation:

Use FOIL:

$y^4$ + $\frac{-14}{5}y^2$ + $\frac{5}{7}y^2$ + $\frac{-70}{35}$

Make $\frac{-14}{5}y^2$ and $\frac{5}{7}y^2$ have the same numerator:

$\frac{-14*7}{5*7}y^2 =\frac{-98}{35}y^2$

$\frac{5*5}{7*5} y^2=\frac{25}{35} y^2$

Then add like terms and simplify:

$y^4$ + $\frac{-98}{35}y^2$ + $\frac{25}{35} y^2$ + $\frac{-70}{35}$

$y^4$ + $\frac{-73}{35}y^2$ - $2$

PQR is an isosceles triangle in which PQ = PR

otez555 [7]

Answer and Step-by-step explanation: Congruent triangles are triangles with the same three sides and same three angles.

There many ways to determine if 2 triangles are congruent.

One of them is ASA or Angle, Side, Angle and it means that if two angles and the included side of one triangle are equal to the corresponding angles and side on the other triangle, they are congruent.

In this case, angle MRQ and angle NQR are equal. The included side of both triangles are the same QR, so it can be concluded that triangle QNR is congruent to triangle RMQ.

The image in the attachment shows the angles and their included side, which are colored.

Please help me out with this problem!

MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

The red graph is the graph of y = f(x) shifted 1 unit right and then reflected in the x- axis.

Given y = f(x) then f(x + a) is a horizontal translation of a units

• If a > 0 then shift to the left of a units

• If a < 0 then shift to the right of a units

Here shift to the right of 1 unit, thus

y = f(x - 1)

Under a reflection in the x- axis

a point (x, y ) → (x, - y )

Note the y- coordinates are the negative of each other, thus

- y = f(x)

Now $\frac{y}{-1}$ = - y, hence

The equation for the red graph is

$\frac{y}{-1}$ = f(x - 1) → C
