Answer:
Yes
Step-by-step explanation:
( x, y ) = ( 3, - 10 )
Here,
x = 3
y = - 10
y = - 4x + 2
- 10 = - 4 ( 3 ) + 2
- 10 = - 12 + 2
- 10 = - 10
LHS = RHS
Therefore,
( 3, - 10 ) a solution to the function y = - 4x + 2.

The perimeters of the triangles shown are equal. Find the side lengths of each triangle.
AB =
PQ=
QR =
BC=
AC =
PR =
Answer:
3x +9 + 3x + 3x +8 = 3x + 3x + 4x + 6
9x + 17 = 10x + 6
x = 11
AB 42
BC 41
AC 33
PQ 33
QR 33
PR 50
Answer:
x = 11
Step-by-step explanation:
if the perimeters are equal then:
the perimeter of the first triangle : 3x + 9 + 3x + 3x + 8 = 9x + 17
the perimeter of the second triangle : 3x + 3x + 4x + 6 = 10x + 6 and
9x + 17 = 10x + 6 export like terms to the same side of the equation
17 - 6 = 10x - 9x
11 = x
we can find the lengths by replacing x with 11 in given expressions.
A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house. This represents 20% of the total exhibits in the reptile house. How many exhibits are in the reptile house?
Answer:
75
Step-by-step explanation:
15 is 20% of the total.
The total is x since it is unknown.
20% of the total = 15
20% of x = 15
0.2x = 15
Multiply both sides by 5.
x = 75

A square playground has an area of 200 m2. Estimate the length of one side.
A: 14m B: 100m C: 20 m
Pick one!
Plzzz help me I will give Brainliest I need Math HW done asap!
Answer:
It should just be 14m .
Step-by-step explanation:
Area is just height x length and since he know that the sides are all equal because it's a square they have to be x amount times x amount 14 x 14 = 197 which is the closest answer we can get with these opions.

m= 19-(-9)/8-(-6)
m=28/14
m=2
CD
m=0-(-4)/2-0
m=4/2
m=2
parallel:m1=m2
perpendicular:m1m2= -1
therefore its parallelWhat is the value of t?
Answer:
32°
Step-by-step explanation:
1) the sum of the angles is 180°. According to this rule the sum can be written:
t+(t+1)+[180-(t+33)]=180;
2) if to solve this equation, then
t=32°
Does the graph represent a function that has an inverse function
9514 1404 393
Answer:
No
Step-by-step explanation:
A horizontal line can be drawn that intersects the graph in more than one place. That means the graph fails the "horizontal line test" and does not have an inverse function.
(The horizontal line shown intersects in 3 places.)

What is the sum of 3/7 + 1/3
Answer:
16/21
Step-by-step explanation:
1) Find the least common denominator (LCD) of 3/7,1/3. In other words, find the Least Common Multiple (LCM) of 7,3.
LCD=21
2) Make the denominators the same as the LCD
[tex]\frac{3*3}{7*3} +\frac{1*7}{3*7}[/tex]
3) Simplify. Denominators are now the same.
[tex]\frac{9}{21} +\frac{7}{21} \\[/tex]
4) Join the denominators
[tex]\frac{9+7}{21}[/tex]
5) Simplify
[tex]\frac{16}{21}[/tex]
Answer:
[tex]{ \tt{ \frac{3}{7} + \frac{1}{3} }} \\ \\ = { \tt{ \frac{(3 \times 3) + (7 \times 1)}{21} }} \\ \\ = { \tt{ \frac{9 + 7}{21} }} \\ \\ = \: \dashrightarrow \: { \tt{ \frac{16}{21} }}[/tex]
How do you break apart 32.14
Answer:
answer is below
Step-by-step explanation:
so 32.14 is breakable. first break it up by the tens place you have 3 tens.
next the ones place you have 2 ones
then the tenths place you have 1 tenth
then the hundredth place you have 4 hundreths
so the 3 tens is equal to 30
the 2 ones is equal to 2
the 1 tenth is equal to 0.1
the 4 hundredth is equal to 0.04
this is easier to understand and is a good way to think about more complext numbers

Everyday a zookeeper feeds 4 adult gorillas a total of 160 lb of food. At this rate, how many pounds of food would the zookeeper need everyday to feed 6 adult gorillas?
Answer:
240 lbs
Step-by-step explanation:
Each gorilla eats a total of 40lbs (found that by dividing the number of gorillas by the pounds, 4/160, which is 40.)
So now that you know the number of pounds for each gorilla, you multiply the pounds by your gorillas ( 40 * 6, which is 240)
Hope this helps!
Answer:
240 he would need 240 to feed 6 gorillas every day

A car travels at an average speed of 45 mph for 40 minutes.
The next part of the car's journey takes 25 minutes at an average speed of 60 mph.
Show that the average speed of the entire journey is just over 50 mph.
9514 1404 393
Answer:
the average speed is 50 10/13 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
distance = speed × time
The distance traveled in the first part of the car's journey is ...
(45 mi/h)(2/3 h) = 30 mi
The distance traveled in the second part of the car's journey is ...
(60 mi/h)(25/60 h) = 25 mi
Then the total distance is 30 mi +25 mi = 55 mi.
The total time is ...
40 min +25 min = 65 min = 65/60 h = 13/12 h
The average speed for the trip is ...
speed = distance/time = (55 mi)/(13/12 h) = 660/13 mi/h = 50 10/13 mi/h
The average speed of the journey is 50 10/13 mi/h, just over 50 mi/h.
An amount increased by 10% to 517.
What was the original amount?
Answer:
470
Step-by-step explanation:
x is the amount that represents 100 %
517 amount that represents 100%+10% increase = 110%
x = (517 *100) / 110 = 470 is the original amount
Write a quadratic equation that has 2 and 8 as solutions.
Find the equation with 1 as the coefficient of the quadratic term.
Answer:
[tex]x^2-10x+16[/tex]
Step-by-step explanation:
The way I would find the equation is by finding the factored form of the equation form. That equation would be (x-2)(x-8). These are correct because if you set both of these equal to zero, your x-values will be equal to 2 and 8.
x-2=0
x=2
x-8=0
x=8
If you want the standard form of the equation, all you have to do is multiply it out.
[tex](x-2)(x-8)\\x(x-8)-2(x-8)\\x^2-8x-2x+16\\x^2-10x+16[/tex]
Boom. There's your answer!
