10d + 20 = 100 pls answer quick
Let's solve your equation step-by-step.
10d+20=100
Step 1: Subtract 20 from both sides.
10d+20−20=100−20
10d=80
Step 2: Divide both sides by 10.
10d
/10= 80/10
so d= 80
forgot the zero
Evaluate all three please i don't know any of those :(
PLS help ASAP this really urgent
Answer:
Skewed right.
Step-by-step explanation:
The graph is not symmetric because it's not an exact mirror of each side if you drew a line in the center. If the graph has highpoints on the left side and is leaning down to the right, it's skewed right. Same thing vice versa.
Pls helppp 3 part question
Erik transformed the equation y = 2(x − 2)^2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)^2 + 5
y = 2(x^2 − 4x + 4) + 5
y = 2x^2 − 8x + 8 + 5
y = 2x^2 − 8x + 13
A. No. The error is in the second line: the expanded form of (x − 2)^2 is x^2 − 4.
B. No. The error is in the third line: the product of 2 and x^2 − 4x + 4 is 2x^2 − 4x + 4.
C. No. The error is in the fourth line: the sum of 8 and 5 is 12.
D. Yes. Erik is correct in his transformation from vertex form to standard form.

a = 6
b = 48
Step-by-step explanation:
3*2^1 = 6
3*2^4 = 48
Answer:
a. 6
b. 48
Step-by-step explanation:
It is cut off, but I believe the expression is 3 x 2^t
For a. plug in "1" for "t" so the expression would look like 3 x 2^1. 2^1 is just 2 and 3 x 2 is 6. Answer is 6.
For b. plug in "4" for "t" so the expression would look like 3 x 2^4. 2^4 is 16 and 16 x 3 is 48. Answer is 48.

Data Set: 5, 8, 10, 10, 15, 18, 23. What is the upper quartile limit (Q3) of this data set? *
Answer:
15, 18, and 23
Answer:
Q₃ = 18
Step-by-step explanation:
The first step is to find the median
The median is the middle value of the data in ascending order.
5, 8, 10, 10, 15, 18, 23
↑ middle value
median = 10
The upper quartile Q₃ is the middle value of the data to the right of the median, that is
15, 18, 23
↑ middle value
Thus Q₃ = 18

If F(x) = x² + 5x and G(x) = 2x + 1, find F(5) + G(6). 48 63 107
Answer:
63
Step-by-step explanation:
F(x) = x² + 5x
F(5) = (5)² + 5(5) = 25 + 25 = 50
G(x) = 2x + 1
G(6) = 2(6) + 1 = 12 + 1 = 13
F(5) + G(6) = 50 + 13 = 63

[tex]\Huge\boxed{x=29}[/tex]
Step-by-step explanation:
Hello There!
Once again the angles shown are supplementary angles meaning that the sum of the measure is equal to 180
so we use this equation to solve for x
180 = x + 4x + 35
step 1 combine like terms
x + 4x = 5x
now we have 180=5x+35
step 2 subtract 35 from each side
180 - 35 = 145
35 -35 cancels out
now we have 145 = 5x
step 3 divide each side by 5
5x/5=x
145/5=29
we're left with x = 29
Answer:
(×+35)+4×=180°[sum of angles in a str. line ]
5×=180-35
5×=145
5x/5=145/5
x=29
how do I get the answer like you don't even have to tell me the answer just tell me how to get the answer

What is the slope of the line that goes through the points (6, 4) and (8, -2)?
-6
-3
-1/3
3
Answer:
-3
Step-by-step explanation:
(6, 4) and (8, -2)
Slope:
m=(y2-y1)/(x2-x1)
m=( -2 -4)/(8-6)
m = (-6)/2
m = -3
Answer:
-3
Step-by-step explanation:
(6, 4) and (8, -2)
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-2 - 4) / (8 - 6)
Simplify the parentheses.
= (-6) / (2)
Simplify the fraction.
-6/2
= -3
This is your slope.
