PLEASE HELP ME WITH THE LITTLE QUESTION
Answer:
y = -x +2
Step-by-step explanation:
First let's find the slope.
(-1,3) and (4,-2)
3 - -2/ -1 - 4 = 5/-5 = -1
Slope = -1
Now let's use slope intercept form:
y1-y2=m(x1-x2)
Let's plug in our slope for m.
y1-y2= -1 (x1-x2)
And now let's substitute y2 and x2 for one of our points, I'll use (4,-2)
y1+2 = -1(x1- 4)
y= -x + 4 -2
y = -x +2

12. The quotient of x divided by six is eight.
13. 28 is four times the number x
Help!!!! lol
Answer:
12. x = 48
13. x = 7
Step-by-step explanation:
x/6 = 8
x = 8*6
x = 48
28 = 4x
28/4 = x
x = 7
Answer:
12) x/6 = 8
13) 28 = 4x

Which values are the solutions to the inequality below? Check all that apply.
X^2 < 10
Answer:
3
Step-by-step explanation:
if you can't use calculator, you must know that after a number being square root, it MUST be in positive
for the negative answer will be false
so for the rest of the answer you need to try it
3² = 9 < 10 so it's true
4² =16 > 10 so it's false
the only answer is 3

What is the equation of this table?
plzz help me
y=1/2X+5 or y=X/2+5 is the equation
PLEASE HELP ASAP‼️‼️
A
B
C
D
Answer:
The answer is 12.
Step-by-step explanation:
The triangles are similar, meaning that they have the same ratio. To figure out the ratio, you can see that the smaller triangle has a length of 5 for side AB. The corresponding side on the larger triangle, LM, has a length of 10. When you divide 10 by 5, you get 2, meaning that the triangle on the right is 2 times larger than the one on the left.
Now that we know that, we can solve for side AC. To do this, set up an equation for the corresponding sides. Since the larger triangle is 2 times larger, the equation would look like this: 2(x+5) = 3x+3.
That would simplify out to 2x+10 = 3x+3. Subtract 2x from both sides to get the equation 10 = x+3. Finally, subtract 3 from both sides to get 7 = x.
Now you can solve for side AC. Substitute the x in the equation for 7, giving you 7+5. That equals 12, your final answer.
I hope this makes sense! ☺
a living room floor consists of an area and hardwood. the area of the rug is 187 square feet. what is the area of the entire living room. (i'm attaching a picture for the rest of the problem) 20 points and brainliest if you answer correctly.
Answer:
x = 20 ft
Area of the living room = 400 ft²
Step-by-step explanation:
From the picture attached,
Length of rug = (x - 3) ft
Width of the rug = (x - 9) ft
Area of the rectangular rug = Length × Width
= (x - 3)(x - 9)
187 = (x - 3)(x -9)
187 = x² - 12x + 27
x² - 12x - 160 = 0
x² - 20x + 8x - 160 = 0
x(x - 20) + 8(x - 20) = 0
(x - 20)(x + 8) = 0
x = -8, 20
Since, measure of 'x' can't be negative, measure of x will be 20 ft.
Therefore, area of the square living room = x²
= (20)²
= 400 ft²

FIND THE VALUE OF X
Answer: 15
Step-by-step explanation:
8x-60°
8(15)-60°
120°-60°
60°
X WILL EQUAL 15 BECAUSE 120 - 60 WILL EQUAL 60!
THE TRIANGLE MUST ADD UP TO 180°!!
Answer:
x=15
Step-by-step explanation:
too hard to explain but
all triangles are 180 degrees
so
60 plus 60 = 120
180-120 = 60
60+60=8x
120=8x
120/8 =
15
A cognitive psychologist is interested in whether increasing reading speed reduces comprehension. She has students complete a reading comprehension task before and after a six-week speed-reading course. In the beginning of the study, a randomly selected group of 81 students scored an average of 107 points on the reading comprehension task. Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of MD is normal. She plans to use a repeated-measures t test. The cognitive psychologist identifies the null and alternative hypothesis as:
Answer:
H0: Ud >= 0
H1: UD < 0
Step-by-step explanation:
We have the sample size = 81
Mean of x = 107
The alpha level was not given for me to help you calculate further.
This researcher wants to know if increasing reading speed brings about a decrease in the comprehension of the reader.
The hypothesis are
Null hypothesis
H0: U >= 0
Alternative hypothesis
H1: U < 0

Max has $300 in a savings account. He plans to withdraw $10 per week for lunch money. Which inequality
represents the number of weeks Max can withdraw money before his account will be less than $170?
Answer:
300-10w<170
subtract 300 from both sides
-10w<-130
divide by -10, because we are dividing a negative number the inequality sign changes
w>13
(brainlyest appreciated!)
1. Diego has 75% of $10. Noah has 25% of $30. Diego thinks he has more money than Noah, but Noah thinks they have an equal amount of money. Who is right?
Select the correct choice.
Step-by-step explanation:
To find how much 75% we multiply 100 with 75 and divide it with 100
75 × 10 ÷ 100 = 7.5
we need to do same with Noah's money
25 × 30 ÷ 100 = 7.5 Noah is correct, they have same amount.

Find the area. HELP ME PLEASEEEEEEEEEEEEEEEEEEEEEEEee
Answer:
area = 132 cm²
Step-by-step explanation:
area of rectangle = 7 x 12 = 84
area of one triangle = 8 x 6 x 0.5 = 24
total area = 84 + 24 + 24 = 132 cm²
plsssssssss help!!!!!!!!!!!!!!!!!
Answer:
C) ∠LMO = 50°
Step-by-step explanation:
When you add the degrees of all the angles in a triangle, you get 180, so...
180 = 60 + 70 + x
180 - 60 - 70 = x
x = 50
Answer:
C

what is the area of the composite shape below?
A circle has a radius of 12.6 cm. What is the exact length of an arc formed by a central angle measuring 100°?
the answer choices are in the picture please help i’ll give brainliest!!
Answer: Your answer should be 8.5 π
The formula to find the length of an arc is:
m ∘ 360 ∘ 2 π r
120 /360 2 π ( 12.6 )
120 /360 25.2 π
Simplify 120 /360 to 1 /3 and finish the other simplifying:
1 /3 25.2 π
25.2 /3 π
Since they want the answer expressed by π , 8.5π is the answer.
Answer:
I just took the test and got it wrong the first time. The correct answer is: 7π cm.

A right triangle table top has legs that
measure 3.5 feet. What is the perimeter
of the table top?
Answer:
i
Step-by-step explanation:
Answer:
12 feet
Step-by-step explanation:
use the pythagorean theorem to figure out what the hypotenuse is
3.5^2+3.5^2=x^2
12.25+12.25=x^2
25=x^2
x=5
now that you know the hypotenuse, you can find the perimeter by adding up all the sides
3.5+3.5+5=12

What two numbers have a sum of -7 and a difference of 14?
Answer:
The sum of two numbers is 14 and their difference is 10
Step-by-step explanation:
"2 numbers (x and y)
x+y = 14
and x-y + 10
If you each equation by positive 2, one gets 2x+2y = 28 and 2x-2y = 20
The 'y-terms' cancel out or equal zero when adding, so 4x = 48, divide by 4 on each side and x or the first number equals 12.
Plug 12 back into the equation for 'x' and subtract 12 on both sides so that y=2
The difference of 12-2=10 and the addition of 12 and 2 equals 14"
