Follow the equation Y=mx+b
B is the y intercept
To find the y intercept of the graph find where the graph crosses the y axis. That’s at -1
Then use rise over run
3 up, 2 over
So slope is -3/2

Answers
Answer:
(9 x 7)/3 + 4
Step-by-step explanation:
9 x 7 = 63
63 divided by 3 is 21.
21 + 4 = 25
Answer:
(9*7)/3+4
Step-by-step explanation:
if you do 9*7 you get 63
then if you divide 63 by 3 you get 21
finally, add 21 to 4 and get 25

Median without outlier should be 40
For the bottom questions, it should go:
Decreases the mean, does not change the median, does not change the mode
It's decreasing the mean because it goes from 44.7 to 39
Median w/ and without outlier is both 40
Mode also stays the same w/ or without the outlier, which is 96

How many litters of apple syrup and water did she use in the ratio of 2:3 and made 1800 ml of such fruit juice
Answers
Answer:
720 mL ; 1080 ml
Step-by-step explanation:
Givenn:
Apple syrup : water = 2 : 3
Fruit juice volume made using the ratio above = 1800 ml
Sum of ratio = 2 + 3 = 5
Litres of Apple syrup :
(Syrup ratio / total) * total volume of fruit
(2 / 5) * 1800
= 0.4 * 1800
= 720 ml
Litres of water :
(water ratio / total) * total volume of fruit
(3 / 5) * 1800
= 0.6 * 1800
= 1080 ml

G f(x) = -2x2 + 12x - 10
H f(x) = -0.5(x - 3)2 + 2
J f(x) = -0.5x² – 3x - 6
Answers
9514 1404 393
Answer:
H f(x) = -0.5(x -3)² +2
Step-by-step explanation:
The quadratic opens downward, so the leading coefficient is negative. All answer choices agree on this.
The vertex (maximum point) is (3, 2). Choices F and H are written in vertex form. Choice F has a vertex of (3, 8); choice H has a vertex of (3, 2), so is a likely candidate.
When we look at the graph 1 unit right or left of the vertex, we see that it is about 1.5, that is, 0.5 units below the vertex. This 0.5 is the magnitude of the leading coefficient, which we already know is negative. The leading coefficient of -0.5 eliminates choices F and G.
So, choice H has the correct leading coefficient and the correct vertex.
Choice J can be eliminated by looking at the value for x=0. For J, it is -6, but we see the y-intercept of the graph is -2.5. This eliminates choice J.
The only viable choice is H.

In ARST, the measure of ZT=90°, the measure of ZR=24°, and RS = 3.8 feet. Find
the length of ST to the nearest tenth of a foot.
Answers
Answer:
1.55 feet.
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle R = 24°
Hypothenus = RS = 3.8 feet
Opposite = ST = x
The value of x can be obtained by using the sine ratio. This is illustrated below:
Sine R = Opposite / Hypothenus
Sine 24 = x / 3.8
Cross multiply
x = 3.8 × Sine 24
x = 3.8 × 0.4067
x = 1.55 feet
Thus, the Lenght ST is 1.55 feet.

Write an explicit formula for the geometric sequence below and use it to find the 9th term. 256, 64, 16, 4, . . .
Answers
im doing this problem right now---
ok so a1=256 a2=64 a3=15 a4=4... find a9
the sequence divides by 1/4 every term
an=a1*r^n-1
an=(256)*(1/4)^n-1
replace n with 9
A9=(256)*(1/4)^9-1
A9=(256)*(1/4)^8
=(256)*(1/4)
A9=64^8
1/256 or a9= 0.00390625

Which of the following is an equation of the circle with a center at (-1,4) and a radius of 2√5 units? plss pahelp naman
A. x²+ y²+2x-8y-3=0
B. x²+y²-2x-8y+3=0
C. x²+y²+2x+8y-3=0
D. x²+y²-2x+8y+3=0
Answers
Answer:
Option A
Step-by-step explanation:
The standard form of an equation of a circle is represented by the formula [tex](x-h)^2+(y-k)^2 = r^2[/tex]. Remember that [tex](h,k)[/tex] is the center and [tex]r^2[/tex] is the radius squared.
So, the equation of the circle must be [tex](x+1)^2 +(y-4)^2 = 20[/tex]. Complete the square to change the form of the equations listed in the options and find the one that is equal.
Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:
[tex]x^2 + y^2 +2x -8y -3 = 0\\x^2 + y^2 +2x-8y = 3\\x^2 + 2x +y^2-8y = 3\\(x^2 +2x+1)+(y^2-8y +16)=3+1+16\\(x+1)^2 + (y-4)^2=20[/tex]
The end result matches with the equation determined before, so option A is the answer.

Periodic graphs repeat the same pattern. Here we have a cosine function which clearly repeats itself. Start at (0, 1) and count the number of squares to the right before the graph looks the same; this occurs at (4π, 1). x has increased from 0π to 4π. Thus, the period is 4π.

Answers
Answer:

Step-by-step explanation:
Answer:
g(f(-9))=4
Step-by-step explanation:
This is a composite function so we need to first find the value of the function on the inside in order find the value of the composite function
f(-9)=x+7=-9+7=-2
we can put -2 instead of f(-9) in the composite function
g(-2)=(-2)^2=4
