Haley’s Percentage Decrease from Test 1 to Test 2 to the nearest tenth is 7.5%
Nearest tenth can be defined as , Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5
Given that,
Haley’s Percent score in Test 1 = 93 %
Haley’s Percent score in Test 2 = 86%
Formula For calculating the Percentage Decrease is :
(Beginning Percentage – Final Percentage) / Beginning Percentage * 100
So, by using this formula we can calculate the percentage decrease of Haley’s Test
Percentage Decrease = (93% - 86%)/93% * 100
= 7.5%

Answer:
-1
Step-by-step explanation:
Slope = rise over run
I’m assuming what you’re asking here is how to *factor* this expression. For that, let’s rearrange the expression into a more familiar form:
-c^2-4c+21
From here, we’ll factor out a -1 so that we have:
-(c^2+4c-21)
Let’s focus on the quadratic expression inside the parentheses. To find our factors (c + x)(c + y), we’ll need to find two terms x and y that multiply together to make -21 and add together to make 4. It turns out that the numbers -3 and 7 work out perfectly for that purpose (-3 x 7 = -21 and 7 + (-3) = 4), so substituting them in for x and y, we have:
(c + (-3))(c + 7)
(c - 3)(c + 7)
And adding back on the negative from a few steps earlier:
-(c - 3)(c + 7)
