use the Pythagorean theorem
9^2 = 4^2 + x^2
81 =16 +x^2
x^2 = 65
x = 8.06 feet
Solve the quadratic equation numerically (using tables of x- and y- values).
x squared + 2 x + 1 = 0
Answer:
x=-1
Step-by-step explanation:
Step 1: Factor
[tex]x^{2} +2x+1[/tex] => [tex](x+1)(x+1)[/tex]
Step 2: Solve for x.
[tex]x+1=0[/tex]

Joy has a ribbon that measures 16 yards. She cuts 9 pieces of ribbon to decorate gifts. Each piece of ribbon that Joy cuts measures 4 feet.
What is the length, in yards, of the remaining ribbon?
Answer:
4 yds
Step-by-step explanation:
So... 16 yards is 48 feet (because one yard is 3 feet so I just multiplied by 3)
and she cuts 9 pcs of ribbon each 4 feet
so it's 9 x 4 = 36
48 - 36 = 12
And 12 feet equals 4 yards
So, Joy has 4 yards of remaining ribbon
Answer:
9.3 yards
Step-by-step explanation: the exact answer is 9.3333333

If the sum of measures of angle a and b is 280 degrees, what is the measure of angle C?
A. 80 degrees
B. 160 degrees
C. 140 degrees
D. 40 degrees
Answer:
40 degrees
Step-by-step explanation:
because angle b and angle a are vertical angles they are congruent and if they add up to 280 you just have to divide that by 2 to get the value of one of the angles
280/2=140
because angle c and angle b are supplementary they are going to add up to equal 180
180-140=40 so c=40
Answer:
40

Which expression is equivalent to the expression below?
2(6k+4)−4(2+2k−1)
-------------------------------------------------------------------------
a} 18+48k
b} 14k−1
c} 4k−4
d} 4+4k
Answer:
D. 4+4k
Step-by-step explanation:
(12k +8) - (8+ 8k - 4)
12k +8 - 8 - 8k + 4
4k +4
d}4+4k
2(6k+4)-4(2+2k-1) writing down the question
12k+8-8-8k+4 multiplying the numbers by the coefficients
12k-8k+8-8+4 collecting like terms
4k+4 the answer

Hope this helps! :)
Answer:
1
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(-3 + 12) / (15 - 6)
9 / 9
= 1
So, the slope is 1

expected to increase by 15% each year.
Calculate how many emergency packages the charity expects to distribute in 2021.
Answer:
121670
Step-by-step explanation:
The number of packages can be defined with the function:
P(t) = P(t-1)*1.15 where t = the years and 1.15 represents the 15% increase.
Packages during 2018: P(2018) = 80000
Packages during 2019: P(2019) = P(2018)*1.15 = 92000
Packages during 2020: P(2020) = P(2019)*1.15 = 105800
Packages during 2021: P(2021) = P(2020)*1.15 = 121670
