Answer:
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]
Step-by-step explanation:
The slope-intercept form of line is given by the formula:
[tex]y = mx+b[/tex]
Here m is the slope and b is the y intercept
Given
[tex](x_1,y_1) = (1,2)\\(x_2,y_2) = (8,9)[/tex]
First of all, the slope has to be found
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{9-2}{8-1}\\m = 1[/tex]
Putting m=1 in the equation
[tex]y = x+b[/tex]
Putting the point (1,2) in the equation to find the value of b
[tex]2 = 1+b\\b = 2-1\\b = 1[/tex]
The equation is:
[tex]y = x+1[/tex]
Hence,
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]
Express as a trinomial.
(2 – 4)(2x + 3)
Answer:
-2(2x+3)
Step-by-step explanation:
Answer:
-2 (2x + 3)
Step-by-step explanation:
We need to use FOIL
Multiply the FIRST terms of each set together
Then the OUTSIDE terms
Then the INSIDE terms
and then the LAST terms
Thus:
[tex]2*2x = 4x[/tex]
[tex]2*3 = 6[/tex]
[tex]-4*3 = -12[/tex]
[tex]-4*2x = -8x[/tex]
So finally we end up with 4x + 6 - 12 - 8x
Simplifying this gives us -4x - 6
We can then factor out -2 from each factor, giving: -2(2x+3)
Hope this helps!

A circle has a radius of 4 feet. What is the radius of a bigger circle if the scale factor of the smaller to bigger is 4:9
Answer:
9 feets
Step-by-step explanation:
From the question, we have our scale factor as:
4:9 = 4/9
Smaller circle /Bigger circle = 4/9
A circle has a radius of 4 feet. What is the radius of a bigger circle?
Let the radius of the bigger circle = x
This is calculated as:
4/9 = 4/x
Cross Multiply
4x = 9 × 4
x = 36/4
x = 9 feet
Therefore, the radius of the bigger circle is 9 feet
What’s 25 dived by 9 in long (step by step)
Answer:
Step 1:
Start by setting it up with the divisor 9 on the left side and the dividend 25 on the right side like this:
9 ⟌ 2 5
Step 2:
The divisor (9) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:
0
9 ⟌ 2 5
Step 3:
Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.
0
9 ⟌ 2 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.
0
9 ⟌ 2 5
- 0
2
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
9 ⟌ 2 5
- 0
2 5
Step 6:
The divisor (9) goes into the bottom number (25), 2 time(s). Therefore, put 2 on top:
0 2
9 ⟌ 2 5
- 0
2 5
Step 7:
Multiply the divisor by the result in the previous step (9 x 2 = 18) and write that answer at the bottom:
0 2
9 ⟌ 2 5
- 0
2 5
1 8
Step 8:
Subtract the result in the previous step from the number written above it. (25 - 18 = 7) and write the answer at the bottom.
0 2
9 ⟌ 2 5
- 0
2 5
- 1 8

Answer:
bratdth = 8 m
perimeter = 12 m
we know
perimeter of rectangle = 2(l+b)
24=2(l+8)
24=2l+16
24-16=2l
8=2l
8/2=l
l=4m
for second picture
breadth = 5m
length =4 m
p =?
we know
p= 2(l+b)
p=2(4+5)
p=2×9
p=18m

Franklin uses the distributive property to write an expression equivalent to 18 + 36. Which of the following best represents Franklin's expression?
18(1+ 4)
18(2 +2)
6(2+6)
Answer: 9(2+4)
Step-by-step explanation:
18 + 36 = 54
18(1+4) = 90
18(2+2) = 72
9(2 + 4) = 54
6(2+6) = 48
The best representation of the expression 18 + 36 after using distributive property is 18(1 + 2).

marys age is 2 upon 3 that of peters age. two years ago marys age was 1 upon 2 of whats peters age will be in 5years time. how old is peter now plzz
Answer:
the Peter age be 27
Step-by-step explanation:
Let assume peter be
And, then mary is 2p ÷ 3
So
The equation would be
2p ÷ 3 - 2 = 1 ÷ 2 (p + 5)
4p - 12 = 3p + 15
p = 27
So Peter age be 27
And, the mary age is
= 2 (27) ÷ 3
= 18
Hence, the Peter age be 27
