Answer:
no solutionStep-by-step explanation:
to understand thisyou need to know about:system of linear equationtips and formulas:a system of linear equation has no solution if [tex]\frac{a_1}{a_2}=\frac{b_1}{b_2}\neq \frac{c_1}{c_2}[/tex]let's solve:according to the question
[tex] \frac{3}{21} = \frac{4}{28} \neq \frac{17}{109} \\ \frac{1}{7} = \frac{1}{7} \neq \frac{17}{109} [/tex]
therefore
the system of linear equation has no solution

-5x+8y=-36
5x+7y=6
Answer:
x=4, y=-2
Step-by-step explanation:
-5x+8y=-36
5x+7y=6
eqn 1+ eqn 2 gives
15y=-30
divide both sides by 15
y=-2, put in eqn 2
5x+7(-2)=6
5x=20 divide both sides by 5
x=4

Find the value of x to the nearest tenth.
Answer:is it 1
Step-by-step explanation:
Are the lines parallel, perpendicular, or neither show work cause I need to understand this
Answer:
Niether
Step-by-step explanation:
the slopes arent opposite so they arent perpendicular, they arent the same so they arent parallel. they are niether due to thier slopes, but if they had the same slope, the y intercept would have to be different for them to be parrallel or else they would be the same line

find the value of x in the isosceles triangle shown below.
V80
V80
Answer:
Option A. x = 8
Step-by-step explanation:
Please see attached photo.
From the attached photo,
we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:
(√80)² = 8² + y²
80 = 64 + y²
Collect like terms
80 – 64 = y²
16 = y²
Take the square root of both side
y = √16
y = 4
Finally, we shall determine the value of x. This can be obtained as follow:
From the attached photo,
x = 2y
but:
y = 4
Therefore,
x = 2y
x = 2 × 4
x = 8

Answer:
7. Orthocenter is on the triangle, at (0,0).
8. Orthocenter is outside the triangle, at (1,-5)
Step-by-step explanation:
Answer:
7. (0, 0) - on the triangle8. (1, -5) - outside the triangleStep-by-step explanation:
Question 7Given points:
J(1, 3), K(-3, 1), L(0,0)Orthocenter is the intersection of altitudes. Altitude is perpendicular segment with one end on the opposite vertices.
Lets work out two altitudes and find their intersection.
Slope of JL
m(JL) = (0 - 3)/(0 - 1) = 3Equation of the line that is perpendicular to JL and passes through K(-3, 1). The line has the slope -1/3.
y - 1 = -1/3(x - (-3)) ⇒ y = -1/3xSlope of KL
m(KL) = (0-1)/(0 - (-3)) = -1/3Equation of the lines that is perpendicular to KL and passes through J(1, 3). The line has a slope -1/(-1/3) = 3
y - 3 = 3(x - 1) ⇒ y = 3xThe orthocenter is the intersection of the lines:
-1/3x = 3x ⇒ x = 0 ⇒ y = 0The point is (0, 0) which overlaps with point L so it is on the triangle
Question 8Given points:
D(-3, -2), E(-2, -2), F(1,2)Lets work out two altitudes and find their intersection.
Slope of DE
m(DE) = (-2 - (-2))/(-2 -(-3)) = 0, horizontal lineEquation of the line that is perpendicular to JL and passes through F(1, 2). The line is vertical:
x = 1Slope of EF
m(EF) = (2- (-2))/(1 - (-2)) = 4/3Equation of the lines that is perpendicular to EF and passes through D(-3,-2)
The line has a slope -1/(4/3) = -3/4:
y - (-2) = -3/4(x - (-3)) ⇒ y = -3/4x - 17/4The orthocenter is the intersection of the lines:
x = 1y = -3/4 - 17/4 = -20/4 = -5The point is (1, -5) is outside the triangle
Find the missing term in the geometric sequence. 180,___,5
Answer:
30.
Step-by-step explanation:
first term = a
3r term = ar^2
So here ar^2/ a = r^2
r^2 = 5/180 = 1/36
r = 1/6
So missing term = 180 * 1/6 = 30.

What percent of the time will the point be in the shaded region
Answer:
29.4%
Step-by-step explanation:
the whole cirlce is 360 degrees which means 100%
to find the percentage of the shaded area, multiply the degrees by 100
⇒ 10.6 x 100 = 10600
then take the product and divide by 360
⇒ 1060 ÷ 360
⇒ 29.44
round to the nearet tenth of a percent
⇒ 29.4

Answer:
answer = 130 degree.
Step-by-step explanation:
I hope is correct.
Answer:
choice 2) angle DOC = 145 degrees
Step-by-step explanation:
angle ABD = 1/2(30 degree arc) = 15 degrees because of the inscribed angle theorem.
angle AOB = 180 - 20 - 15 = 145 degrees
angle DOC = angle AOB because it is a vertical angle to 145 degrees.

In isosceles triangle JKL, JK KL. If the measure of
angle J is 47°, find the measure of angle K.
*Note: Do NOT include the degree in your answer.
Answer:
86
Step-by-step explanation:
Since ∆JKL is an isosceles triangle, it's base angles (<L and <J) would be equal to each other.
<L is opposite to side JK, <J is opposite to side KL.
m<J is given as 47°. Therefore,
m<L = m<J = 47°
m<L = 47°
m<J + m<L + m<K = 180° (sum of triangle)
47° + 47° + m<K = 180° (substitution)
94° + m<K = 180°
m<K = 180° - 94°
m<K = 86°

A local charity receives 1/3 of funds raised during a craft fair and a bake sale. The craft fair raised $252.60. The total amount given to charity was $137.45. How much did the bake sale raise?
Answer:
$159.75
Step-by-step explanation:
137.45/252.60 + x = 1/3
252.60 + x = 412.35
x = 412.35 - 252.60
x = 159.75
Answer:
297.2
Step-by-step explanation:
549.8 ÷ 4 = 137.45
549.8 - 252.60 = 297.2
