Answer:
Your solution is (-1, 0)
Step-by-step explanation:
3x - y = -3
x + y = -1
The elimination method eliminates one variable at a time to find the other variable.
Here we can see that the y variable will naturally be eliminated.
3x - y = -3
x + y = -1
--------------
4x = -4
Divide both sides by 4 to isolate x.
x = -1
Now plug this value back into one of the equations.
3(-1) - y = -3
Multiply.
-3 - y = -3
Add 3 to both sides.
-y = 0
Divide both sides by -1.
y = 0
Your solution is (-1, 0)
Check this solution by plugging these values into the second equation.
-1 + 0 = -1
-1 = -1
Your solution is correct.
Hope this helps!
Answer:
x = -1
y = 0
Step-by-step explanation:
3x - y = -3 -------------------(I)
x + y = -1 ------------------(II)
Add equation (I) & (II). Now, y will be eliminated and you can find the value of x
(I) 3x - y = -3
(I) x + y = -1
4x = -4
x = -4/4
x = -1
Plugin x = -1 in equation (II)
-1 + y = -1
y = -1 +1
y = 0

Answer:
q = 9
Step-by-step explanation:
The angle bisector divides the triangle sides proportionally.
q/36 = (16 -q)/28
7q = 9(16 -q) . . . . . . multiply both sides by 252 (the LCM of 28 and 36)
16q = 16(9) . . . . . . . . add 9q to both sides
q = 9 . . . . . . . . . . . . . divide by 16
_____
Additional comment
We are given the sum of the segment lengths on the far left side. The proportion is the same for the sum of sides as it is for individual sides.
(q/36) = 16/(36+28)
q/36 = 16/64 = 1/4
q = 36/4 = 9

Find the surface area of a square pyramid with side length 5 ft and slant height 7 ft.
5 ft
5 ft
Answer:
99.33ft^2
Step-by-step explanation:
The surface area of a square pyramid is expressed as;
TSA = a²+2a√a²/4 + h²
Given that
a = 5ft
h = 7ft
Substitute
TSA = 5²+2(5)√5²/4 + 7²
TSA = 25+10√25/4 + 49
TSA = 25 + 10√(221/4)
TSA = 25 + 10(√55.25)
TSA = 25 + 10(7.433)
TSA = 25 + 74.33
TSA = 99.33ft^2
Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2
Answer:5x5=25 fts
4(1/2 x 5ft x7 ft) = 70 fts
Add them up and you get
Answer= 95fts

The two figures are similar. Find the missing
dimension. Round to the nearest tenth if
necessary.
Answer:
4 in
Step-by-step explanation:
For the smaller figure, we can assume the other missing side is 2 because the area is 4, and area = length*width.
So the area of the larger figure is 4^2, or 16, so then we can assume the x or the two missing sides for the larger figure are 4 beacuse 4*4=16

1. Ernie Boddy had $3,620.00 on deposit at savings bank on July 1. The money earns interest at a rate of 6.5% compounded quarterly. a. What is the amount in the account on April first of the following year if no deposits or withdrawals were made? B. How much is the compound interest?
Answer:
235.3$ for part a
The amount in the account on April first of the following year is $3799.358 and the compound interest is $179.358.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
(a) The amount in a compound interest can be found as,
A = P(1 + [tex]\frac{r}{n}[/tex]) ^(nt)
where A is the final amount, P is the initial or principal amount, r is the interest rate, n is the number of times compounding occurs in a year and t is the number of years.
Given P = $3,620, r = 6.5% = 0.065, t = 9 months = 0.75 year
n = 4 (since compounded quarterly)
A = 3620 (1 + [tex]\frac{0.065}{4}[/tex]) ^(4 × 0.75)
= 3620 (1.01625)³
= 3799.358
(b) Compound Interest = Final amount - Initial amount
= 3799.358 - 3,620
= $179.358
Hence the compound interest is $179.358.

- 27°. Find m_X.
Answer:
m<X = [tex]126^{o}[/tex]
Step-by-step explanation:
From the given isosceles triangle, we have;
<W and <V as the base angles
So that,
m<W = m<V = 27 (base angles of an isosceles triangle are equal)
Thus,
m<X + m<V + m<W = 180 (sum of angles in a triangle)
m<X + 27 + 27 = 180
m<X + 54 = 180
m<X = 180 - 54
= 126
m<X = [tex]126^{o}[/tex]

how long would a rock that weighs 2 pounds take to fall 99 feet
Answer:
When you are calculating the amount of mechanical energy used to exert force and move something, you are talking about work being done by a force at a distance. You can describe this in terms of foot-pounds. For example, you want to calculate the energy used to tighten a nut when using a wrench, or to lift a weight from the floor. Mechanical force takes place in time, so to describe the power requirement, you use foot-pounds per second.

In ΔDEF, the measure of ∠F=90°, the measure of ∠D=20°, and EF = 92 feet. Find the length of FD to the nearest tenth of a foot.
Answer:
FD ≈ 252.8 feet

By applying tangent rule in the given right triangle,
tan(20°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(20°) = [tex]\frac{EF}{FD}[/tex]
0.36397 = [tex]\frac{92}{FD}[/tex]

Write the equation of the
line in slope intercept form
that contains the points
(-3,-2) and (-2,3).
Answer:
y=5x+13
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-(-2))/(-2-(-3))
m=(3+2)/(-2+3)
m=5/1
m=5
y-y1=m(x-x1)
y-(-2)=5(x-(-3))
y+2=5(x+3)
y=5x+15-2
y=5x+13
Answer:
y = 5x + 13
Step-by-step explanation:
Slope = delta y/ delta x
(3-(-2))/(-2-(-3))
(5)/(1) = 5
Slope = 5
y = 5x + b
Find the y-intercept through substitution:
(-2,3)
3 = 5(-2) + b
3 = -10 + b
13 = b
