Step-by-step explanation:
The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.
PLEASE SOMEONE HELP ME!!!!!!!!
Answer:
The slope is -4
Step-by-step explanation:
To find the slope in this equation you first need to find the difference of y.
2 + (-4) = -2
-2 + (-4) = -6
so the difference of y is -4
Then you find the difference of x
0 + 1 = 1
1 + 1 = 2
So, the difference of x is 1
slope is rise over run (rise meaning the y-axis and run meaning the x-axis)
so the slope is -4/1
=(x+2)^2-4
Identify the vertex
Answer:
vertex = (- 2, - 4 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = (x + 2)² - 4 ← is in vertex form
with (h, k ) = (- 2, - 4 ) ← vertex
Three trees are planted. The direct distance from tree A to tree B is 200 feet. The direct distance between tree B and tree C is 300 feet. What is the direct distance between tree A and tree C?
Answer:
500ftStep-by-step explanation:
DISTANCE BETWEEN TWO POINTS
We want to firstly assume that the the three trees lies on the same line
so tress A,B and C are on the same line
Given
The direct distance between A to B= 200 ft
The direct distance between B to C= 300 ft
hence A to C= 200+300= 500ft
let us do a graphical representation for better understanding
A----B-----------C
200ft 300ft
A---------- -----C
500ft
A to C= 500ft
Answer:
Between 100 and 500
Step-by-step explanation:
A to B is 200
And b to c is 300
A to C =500
200-300=100
Answer = Between 100 and 500

Brandt is buying a new set of golf clubs for
$584. If the clubs are on sale now for 30%
off and sales tax is 7%, how much will he
pay in total?
HHEELLPP I HAVE A TEST TOMOROW!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Original : $437.416 Rounded to Nearest Cent : 437.42
Step-by-step explanation:
Turn 30% into a decimal which is 0.3. Now multiply 0.3 by 584.
0.3 x 584 = 175.2
Now you have to subtract the answer by the original price, $584.
584 - 175.2 = 408.8
Finnaly, you have to find the sales tax of $408.8. In order to find that, you have to convert 7% into a decimal which is 0.07, then multiply it by 408.8. Then you have to add 408.8 to the following answer.(You can change a percent into a decimal by doing the number divided by 100)
0.07 x 408.8 = 28.616
408.8 + 28.62 = 437.42
Here's your answer. I know I'm late.
The cost of the kit is $437.416
What is discount?A deduction from the usual cost of something, typically given for prompt or advance payment or to a special category of buyers.
Given that, Brandt is buying a new set of golf clubs for $584. If the clubs are on sale now for 30% off and sales tax is 7%, we are asked to how much will he pay in total,
The cost of golf kit will be,
= (100-30)% of 584 + 7% of (100-30)% of 584
= 70% of 584 + 7% of 70% of 584
= 408.8 + 28.616
= 437.416
Hence, the cost of the kit is $437.416

The perimeter of a triangle is 13 inches . What is the length of the shortest side?
Answer:
shortest side = 3 in
Explanation:
Sum the 3 sides and equate to 13, that is
x - 5 + 6 + = 13, that is
x + 1 + = 13 ( subtract 1 from both sides )
x + = 12 ( multiply through by 2 to clear the fraction )
2x + x = 24
3x = 24 ( divide both sides by 3 )
x = 8
x - 5 = 8 - 5 = 3 and = = 4 , then
The shortest side is x - 5 = 3 in

Answer:
i think its b or d?
Step-by-step explanation:
=================================================
Explanation:
See the diagram below. I've added blue dots to the image to show where each answer choice is plotted in terms of its (x,y) coordinates.
Any point in the green shaded region is a solution. Any point on the solid boundary line is also a solution as long as the boundary is adjacent to the green inner shaded region.
The horizontal line is dashed, so points along that line are not part of the solution. Think of it as an electric fence you cannot touch. The diagonal boundary line is solid, so we don't have this issue.
---------------------
In the diagram I've labeled the answer choices as A through E
Choices A,B, and D are either in the green inner shaded region or on the diagonal solid boundary line (which is adjacent to the green inner region). So these three points are solutions.
Something like choice C is completely outside the shaded region and not even on a boundary line. So we can rule this point out.
Choice E is the other non-answer because it sits on the dashed boundary line.
Order the numbers 2 , −1/2 , √16, √ 5 , and 4.05 from least to greatest.
Answer:
-1/2, 2, √5, √16, 4.05
Step-by-step explanation:
-1/2 = -0.5
2 is bigger than -0.5 so it goes after -0.5
√5 = 2.24, goes after 2
√16 = 4, goes after √5
4.05 is greater than all these values
At a one-day sale, Alisha bought a skirt for $25. The next day, her friend Merideth bought the same skirt and found that it was marked up 30%. How much did Merideth pay for the skirt?
Answer:
$32.5
Step-by-step explanation:
given that the initial value was
$25
we want to solve for a 30% increase
let us calculate 30% of $25 first which is
30/100*25
=0.3*25
=$7.5
we then have to add this 7.5 to the initial cost
therefore the cost of the skirt Merideth pay

=$32.5
Answer:
32.50
Step-by-step explanation:
find 30 percent of 25, then add it to 25.

Describe one or two ways in which the size of a right triangle affects the sine and cosine values of the triangle's acute angles as well as one or two ways in which it does not affect those values. Predict the minimum amount of information that needs to be known about the acute angles and/or sides of a right triangle for you to be able to solve the triangle, providing examples.
Answer:
Each leg in a right triangle is adjacent to one of the acute angles and opposite the other acute angle.
Keep in mind that the labels “opposite” and “adjacent” depend on which angle you are talking about. The side opposite an angle does not need to be the height of the triangle. Consider the following example:
Step-by-step explanation:
one of the acute angles has a measure of any number.

PLZ HELP ME I AM STRUGGLING!!!!!!!!
Answer:
2/5 & 1/10
Step-by-step explanation:
So, the result we are looking for is 3/2
Simplify the following:
1/5 + 7/10 + 3/5
Put 1/5 + 7/10 + 3/5 over the common denominator 10. 1/5 + 7/10 + 3/5 = 2/10 + 7/10 + (2×3)/10:
2/10 + 7/10 + (2×3)/10
2×3 = 6:
2/10 + 7/10 + 6/10
2/10 + 7/10 + 6/10 = (2 + 7 + 6)/10:
(2 + 7 + 6)/10
2 + 7 + 6 = 15:
15/10
The gcd of 15 and 10 is 5, so 15/10 = (5×3)/(5×2) = 5/5×3/2 = 3/2:
Answer: 3/2
The first square is 3/10+8/10 = 11/10 + 2/5 = 3/2
The second square 9/10+1/2 = 7/5 + 1/10 = 3/2

Romello asked 100 students to choose their favorite subject from among mathematics, history, and art. She found that 22 students chose mathematics, 26 history, and the rest art. What percent of students chose art
Answer:
The percentage of students who chose art is 52 %
Step-by-step explanation:
Given;
total number of students, T = 100 students
number of students who chose mathematics, m = 22
number of students who chose history, h = 26
number of students who chose art, a = 100 - (22 + 26)
number of students who chose art, a = 52
percentage of students who chose art = (a / T ) x (100%)
= (52 / 100) x (100%)
= 52 %
Therefore, the percentage of students who chose art is 52 %
