The equation of line is y= 8x+ 7.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
x y
0 7
1 15
2 23
3 31
4 39
Now, slope= ( 15-7)/ 1-0
slope= 8/1
slope= 8
Now, slope intercept form
y= mx+ b
take y=7 and x=0
7= 0 + b
b= 7
Hence, equation of line is y= 8x+ 7.

Fill in the blanks to find the product of 27 and 45.
27 × 45 = (20 +
) × (40 + 5)
= (20 ×
) + (20 × 5) + (7 × 40) + (7 × 5)
= 800 +

.
Answer: 1215
Step-by-step explanation:
The multiplication 27 × 45 result to 1215
What is Distributive Property?The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.
Given:
27 × 45
Split 27 and 45
= (20 + 7) × (40 + 5)
= (20 × 40) + (20 × 5) + (7 × 40) + (7 × 5)
= 800 ++ 280 + 35
= 1215
Hence, the multiplication result to 1215

3. Alfonso's friend Dani tells Alfonso that her bloodhound, Ol' Sniffy, lived to be 14.
Based on what you know, do you think this was because:
Alfonso didn't use a good estimation method,
Dani doesn't remember Ol' Sniffy's age correctly, or,
Ol' Sniffy lived an unusually long time?
Justify your answer.
It looks like this question wants you to figure out your answer by looking at the chart to see if it looks reasonable.
The first answer doesn't seem to fit the plot so we know that, that inst right. The second one seems like it could work with the question but we dont have enough info to rule it in or out. The third one seems really off because alot of the dogs on the chart lived to be 14 if they where a good weight.
Answer 2: Dani doesn't remember Ol'Sniffy's age correctly, seem like the best fit.

a= (-3a) + 4 help me plz solve
Answer:a=2
Step-by-step explanation:
Simplifying
a = 3a + -4
Reorder the terms:
a = -4 + 3a
Solving
a = -4 + 3a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3a' to each side of the equation.
a + -3a = -4 + 3a + -3a
Combine like terms: a + -3a = -2a
-2a = -4 + 3a + -3a
Combine like terms: 3a + -3a = 0
-2a = -4 + 0
-2a = -4
Divide each side by '-2'.
a = 2
Simplifying
a = 2
