Answer:

Step-by-step explanation:

The coordinates of point P are (-1.4,0.6)

Step-by-step explanation:

We are given A coordinate grid shown from negative 2 to positive 2 on x-axis and negative 2 to positive 2 on y-axis. There are 4 grid lines between a whole unit of the grid.

that means each grid has a value of 0.2.

" A point labeled P is shown at the intersection of 7 grid lines to the left of the y-axis and 3 grid lines above the x-axis "

As P lies on the left of the y-axis and above the x-axis hence the x-value will be negative and y-value will be positive.

According to the given information P lies 7 grid lines to the left of y-axis.

i.e. it has x-value -7×0.2= -1.4

and 3 grid lines above the x-axis i.e. it has y-value:

y-value= 3×0.2=0.6

Hence, the coordinates of Point P are (-1.4,0.6).

What is the correct truth table for ~p^~q?

Kisachek [45]

This symbol - ~ - is the "not" symbol, which means the opposite. So I think were given values for p and q? If so, you just reverse the p values to get ~p (true becomes false or 1 becomes 0 or yes becomes no).
This symbol ^ is the "and" symbol. That means that you need to figure out if both ~p and ~q are true. If so, your result is true (or 1 or yes, depending on which the problem uses). Otherwise, your result is false (or 0 or no) for each corresponding ~p and ~q value.

Answer:

$\displaystyle b = - 14$

$\displaystyle c = - 54$

Step-by-step explanation:

to figure out b we can consider the following formula:

$\displaystyle \frac{ - b}{2a} = h$

the form of vertex coordinate given by

$\displaystyle (h,k)$

so according to the question

$\displaystyle (h,k) = ( - 7, - 5)$

by order pair we obtain:

$\displaystyle h = - 7, k = - 5$

now substitute the value of h and a to the formula:

$\displaystyle \frac{ - b}{2(- 1)} = - 7$

simplify multiplication:

$\displaystyle \frac{ - b}{ - 2} = - 7$

cross multiplication:

$\displaystyle - b = 14$

divide both sides by -1:

$\displaystyle b = - 14$

now we need to figure out C to do so substitute -7 for x and -5 for y which yields:

$\displaystyle - {7}^{2} - 14( - 7) + c = - 5$

simplify square:

$\displaystyle -49 - 14( - 7) + c = - 5$

simplify multiplication:

$\displaystyle -49 + 98+ c = - 5$

simplify addition:

$\displaystyle 49+ c = - 5$

cancel 49 from both sides:

$\displaystyle c = - 54$

hence,

b=-14
C=-54

Answer:

x=5

Step-by-step explanation:

So first you would subtract 2x from both sides to get:

1x = 5

Then you divide both sides by 1:

x = 5

Find the missing side. round to the nearest tenth

irakobra [83]

Answer:

8.8

I don't see that choice in this picture so I hope that those are not all the choices

Step-by-step explanation:

Lets find all the angles first, that highlighted red square means that angle is a right angle, also known as 90 degrees, and the missing angle will be represented with b, also a triangle equals 180 degrees:

48 + 90 + b = 180

138 + b = 180

b = 42

So the missing angle is 42. If u didn't know, how wide an angle is effects the length of the side that it's facing. So because one of the angle is 48 degrees, the length of the side facing it is 10. So we needed to find the missing angle first to determine x, which we already did. So lets find the scale factor, we're dividing 42 with 48:

42/48 = 7/8

Now multiply 7/8 with 10:

10(7/8) = 70/8 = 8.75 = 8.8
