Select the solution(s) to the following equation: (3x−2)(x+5)=0 SELECT ALL THAT APPLY
x=3/2
x=5
x=-5
x=2/3
x=-2/3
x=-3/2
Answer:
Step-by-step explanation:
Check by direct substitution. If we begin by checking x = 3/2, we substitute 3/2 for x in (3x - 2)(x + 5), obtaining (9/2 - 2)(3/2 + 5), which is NOT zero. Therefore x = 3/2 is not a solution.
(3*5−2)(5+5)=0 False. x = 5 is not a solution.
(3*[-5]−2)([-5+5)=0 True. x = -5 is a solution
x = 2/3: (3*2/3 - 2)( ) = 0. True x = 2/3 is a solution
x = -2/3: ( )( ) = -17 1/3; so x = -2/3 is not a solution
x = -3/2: ( ) ( ) = -22 3/4; so x = -3/2 is not a soution

which value for d makes the expressions 3d-4 and 12d÷6 is equivalent
a. 2
b.3
c.4
d.4
Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question. In this lesson, I'll concentrate on the "plug and chug" aspect of evaluation: plugging in values for variables, and "chugging" my way to the simplified answer.

Choose all of the equivalent ratios for 64:80
8:12
32:40
4:5
16:24
120:160
Answer:
32/40, 4/5
Step-by-step explanation:
All these ratios are follow the ratio 4:5 meaning they are equivalent to "64:80".
8:12=0.666667
16"24=0.666667

Find the slope of the points given, and show work
(2,4) and (-3,3)
Answer: 1/5
Step-by-step explanation:
Let's find the slope between your two points.
(2,4);(−3,3)
(x1,y1)=(2,4)
(x2,y2)=(−3,3)
Use the slope formula:
m=y2−y1/x2−x1
=3−4/−3−2
=−1/−5
=1/5

Answer:
A=35, B=55, and C=25
Step-by-step explanation:
Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.
if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B
Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.

Lin's family has completed 80% of a trip. They have traveled 32 miles. How long is the whole trip?
Answer: 50 miles
Find t:
0.70t = 35. Dividing both sides by 0.70, we get:
35
t = ----------- = 50
0.70
The total trip length is 50 miles.

Classify the system of equations.
x= -5 - y
2 + y = -x+3
intersecting
parallel
coincident
Answer:Solve x=−5−y;2+y=−x+3
I will solve your system by substitution.
x=−y−5;y+2=−x+3
Step: Solvex=−y−5for x:
Step: Substitute−y−5forxiny+2=−x+3:
y+2=−x+3
y+2=−(−y−5)+3
y+2=y+8(Simplify both sides of the equation)
y+2+−y=y+8+−y(Add -y to both sides)
2=8
2+−2=8+−2(Add -2 to both sides)

how do you graph/ solve quadratic equations
please hurry and answer correctly
Answer:
384
Step-by-step explanation:
A = (a+b) · h/2
which is an equation of the line
a. y = x - 1
b. y= x + 1
c. y= -x -1
d. y= -x + 1
Answer:
the form is y = mx + b an db is the y intercept. the y intercept is 1 so it is not a or c. The slope is positive, so it is b!!!

Forty students went on a trip on Wednesday. On Thursday, 15% less students went on a similar trip. How many students went on the trip on Thursday?
Answer:
34
Step-by-step explanation:
40 * .15= 6
40-6 = 34
okkk so you do 40 * .15 because you just put a decimal point before all percentages to convert it into number
40*.15= 6
then subtract 6 to the original amount
40-6=34
34 students went on the trip on thursday cause 6 students got killed by bears in the last trip.
