Find the sum
−1/2(7z+4)+15(5z−15)
Answer:[tex]\frac{143x-453}{2}[/tex]
A fish is hovering at –320 feet in relation to sea level. Then it descends 2 feet per second for 8 seconds. Brenda says that the new position of the fish in relation to sea level is represented by the equation below.
2 times 8 + (negative 320) = 336
Which explains whether Brenda is correct?
1. Brenda is correct because her answer represents 336 feet below sea level.
2. Brenda is correct because Negative 16 + (negative 320) = 336.
3. Brenda is not correct because the new position is 2 times 8 + (negative 320) = negative 304.
4. Brenda is not correct because the equation should be Negative 2 times 8 + (negative 320) = negative 336.

length X.
Answer:
50
Step-by-step explanation:
Answer:
sin30°=x/50
1/2=x/50
2x=50×1
2x=50
x=50/2
x=25
tan30°=25/y
[tex] \frac{1}{ \sqrt{3 } } = \frac{25}{y} \\ y = 25\sqrt{3} [/tex]

Point Q is plotted on the coordinate grid. Point P is at (20, −30). Point R is vertically above point Q. It is at the same distance from point Q as point P is from point Q. Which of these shows the coordinates of point R and its distance from point Q?
On a coordinate grid from negative 50 to positive 50 in increments of 10, Point Q is plotted at the ordered pair negative 40, negative 30.
Point R is at (−40, 30), a distance of 60 units from point Q
Point R is at (−40, −10), a distance of 20 units from point Q
Point R is at (−40, −30), a distance of 60 units from point Q
Point R is at (−40, 10), a distance of 20 units from point Q

tom drives at a constant rate of 40 miles per hour for 3 hours.how far will he travel at that time?
A.350 mi.
B.220 mi.
C.120 mi.
D. 60 mi.
Answer: C. 120 mi.
Step-by-step explanation:
To get the answer C you take the constant rate which is 40 and multiply it by the amount of hours which is 3. Hope this helps!
Answer:
C. 120 mi.
Step-by-step explanation:
If he is constantly going 40 miles per hour. That means every hour, he goes 40 miles. So if he drives 3 hours, he would drive 120 miles because 40 miles +40 miles+40 miles=120 miles. Aka 40 times 3 to get 120 miles.

Which equation represents the line through (4, -6) and (0, 2)?
y= -2x + 2
y= 2x - 2
y= 2x + 2
y= -2x - 2
Explain your answer for Brainlest
Answer:
y = 2x+2
Step-by-step explanation:
find gradient by using the gradient formula (m= y2-y1÷x2-x1)
then find C
y= mx+c
the replace c and m in the equation (y=mx+c)
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The Correct equation is :
[tex]y = - 2x + 2[/tex][tex] \large \boxed{ \mathfrak{Explanation}}[/tex]
The given points are :
(4 , -6)(0 , 2)we can see that the y - intercept (c) is 2, from point (0 , 2)
now, let's find the slope (m) :
[tex] \dfrac{2 - ( - 6)}{0 - 4} [/tex][tex] \dfrac{2 + 6}{ - 4} [/tex][tex] \dfrac{8}{ - 4} [/tex][tex] - 2[/tex]now, the equation of line will be :

Which product is negative? −7⋅(−3)⋅(−5)⋅(−8) −3⋅(−4)⋅(−9)⋅0 −2⋅(−4)⋅8⋅(−1) 6⋅(−2)⋅(−3)⋅1
Answer:
-2(-4)(8)(-1)
Step-by-step explanation:
The first choice goes like this:
negetive times negetive times negetive times negetive
and negetive times negetive will always be positive. So teh first choice simplified will be positive times positive which is postive of course. so the first choice is a no-no
the second choice goes lke this:
negetive times negetive times negetive times 0
negetive times negetive= positive
positive times negetive= negetive
BUT
negetive times 0 equals 0, and 0 is positive. So 2nd choice is a no-no
the 3rd choice goes like this:
negetive times negetive times positive times negetive
negetive times negetive equals positive
positive times positive=posive
positve times negetive= negetive
so choice 3 is a yes-yes!
p.s if you see theese kinds of problems dont numerically solve it, just think about negetives and positives, hope it helps ! :>
