Solve the system by substitution.
-5x+2y=-42
6x=y
Step-by-step explanation:
since y=6x
by substitution
-5x+ 2 (6x)= -42
-5x+ 12x=-42
7x= - 42
divide both sides by 7
x= 6
y=6x
y =6*6
y=36

Write the word sentence as an inequality. Then solve the inequality. Three less than a number x is more than 15.
Answer:
x - 3 > 15 ;
x > 18
Step-by-step explanation:
Given a number, x
3 less than x ; x - 3
3 less than x is more than 15
The inequality expression becomes ;
x - 3 > 15
We can solve for X ;
x - 3 > 15
Add 3 to both sides ;
x - 3 + 3 > 15 + 3
x > 18

Answer:
6. Additional information is required on the two triangles
7. The pair of triangles are similar by SAS similarity postulate
8. Yes, by triangle proportionality theorem
9. DE = 9
Step-by-step explanation:
When two or more triangles are similar, the ratio of the corresponding sides of both triangles is constant
6. From the given figure, more information is required on the two triangles
However, whereby the side with length 10 is parallel to the corresponding side on the other triangle, then the alternate angles formed by the transversal to the two parallel lines are equal and the two triangles are similar by Angle Angle, AA, similarity postulate
7. From the given triangles, the ratio of the corresponding sides relative to the given included angles are;
18/45 and 10/25
18/45 = 2/5
10/25 = 2/5
Therefore, given that two pair of corresponding sides have the same included angle and that the two included corresponding sides of the of the two triangles are proportional, then the two triangles are similar by the Side Angle Side SAS similarity postulate
8. By triangle proportionality theorem, we have;
If [tex]\overline{MN}[/tex] ║ [tex]\overline{KL}[/tex], then we have;
3/6 = 4/8 = 2
∴ [tex]\overline{MN}[/tex] ║ [tex]\overline{KL}[/tex]
9. By triangle proportionality theorem, where [tex]\overline{BE}[/tex] ║ [tex]\overline{CD}[/tex], we have;
12/20 = DE/15
∴ DE = 15 × 12/20 = 9
DE = 9
In two or more complete sentences, compare the number of
x-intercepts in the graph of
f(x)=x2 to the number of x-intercepts in the graph of g(x)=−x2−5. Be sure to include the transformations that occurred between the parent function f(x) and its image g(x).
Answer:
Step-by-step explanation:
You meant x^2, right?
We get the graph of g(x) through two transformations of the graph of f(x):
1. Reflect the graph of f(x) about the x-axis.
2. Translate the graph obtained in (1) 2 units down.

A savings account starts with $312.50. After 9 years of continuous compounding at an interest rate, r, the account has $1250.
What is the interest rate percentage?
Round the answer to the nearest hundredth.
P = 312.50
t = 9
r = ?
P(t) = P(9) = 1250
P(t) = Pe^(rt)
P(t) = Pe^(rt)
1250 = (312.50)e^(9r)
1250/312.5 = e^(9r)
4 = e^(9r)
ln(4) = ln(e^(9r))
ln(4) = (9r)ln(e)
[cancel out the e with ln on right side]
ln(4) = (9r)
ln(4) /9 = r
0.15 = r
ANSWER: 0.15 is the interest rateThe compound interest is computed both on the principal and the interest year on year. The rate of the interest is 0.16 or 16%.
What is savings account?A savings account is a type of account where an individual can save money for future purposes.
Here we havethe following information;
Principal = $312.50
Time = 9 years
Amount = $1250.
rate = ?
Using the formula;
A = P(1 + r/n)^nt
Where n =1
1250 = 312.50( 1 + r)^9
1250/312.50 = ( 1 + r)^9
4 = ( 1 + r)^9
1.16 = 1 + r
r = 1.16 -1
r = 0.16 or 16%

A NASA test rocket is launched from the top of a 101 foot cliff with an initial
velocity of 116 feet per second. The function h(t) = -16t2 +116t + 101 gives the
height, h(t), in feet of the rocket t seconds after it's launched.
How long does it take for the rocket to reach the ground?
Answer:
4.018secs
Step-by-step explanation:
Given the height reached by the test rocket by the expression
h(t) = -16t^2 +116t + 101 gives the
The rocket will reach the ground when h(t) = 0
Substitute h(t) = 0 into the expression
0 = -16t^2 +116t + 101
Multiply through by -1
16t^2 -116t - 101 = 0
Factorize using the general formula
t = 116±√(116)²-4(16)(-101)/4(16)
t = 116±√(13,456+6,464)/64
t = 116±√(19,920)/64
t = 116±141.138/64
t = 116+141.138/64
t = 257.138/64
t = 4.018secs
Hence it will take the rocket 4.018secs to reach the ground

Hillary, Ashley, Will, and Carlton were planning a surprise anniversary party for Viv and Phillip. The trip was going to cost the kids a total of $8000. Hillary was willing to pay for 30% of the trip. Carlton was willing to pay for ¼ of what Will paid. Will was going to pay for 2/5 of the trip, and Ashley was going to pay for the rest of the trip. a) Create an equation that could be used to determine how much each person paid for the trip. b) Determine how much each person paid for the trip.
Answer:
Hillary 2400
carlton 800
will 3200
ashley 1600
Step-by-step explanation:
hillary 30% of 8000 ---- 8000:100×30=2400
will 2/5 of 8000 8000:5×2=3200
carlton 1/4 of will's---- 3200:4=800
ashley: rest, which is 8000-(2400+3200+800)=8000-6400=1600

In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound. Donna bought two gallons of milk and some bananas for a total of $2.25 in 1947. How many pounds of bananas did she buy?
Answer:
Answer is 5 pounds of bananas
Step-by-step explanation:
Required milk:
Milk= 2 gallons
Milk cost per gallon=$0.75
so,
2*0.75
$ 1.5
total amount =$2.25
to calculate bananas
$2.25-$1.5=$0.75
per pound cost of bananas =$0.15
$0.75/$0.15
5 pounds of bananas
Dona bought 5 pounds of banana and 2 gallons of milk for a total of $2.25.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound.
Let,The cost of one gallon of milk is 'x' dollars and the cost of one pound of banana is 'y' dollars.
Also given Donna bought two gallons of milk and some bananas for a total of $2.25.
Therefore, 2(0.75) + 0.15y = 2.25.
0.15y = 2.25 - 1.5.
0.15y = 0.75.
y = 0.75/0.15.
y = 5.
So, Dona bought 5 pounds of bananas.

Tell whether the angles are complementary or supplementary. Then find the value of $x$ . A ray intersects two other rays forming a right angle. The angles formed after the intersection is x degrees and left parenthesis x minus 20 right parenthesis degrees.
The measure of the value of x is 55°.
We have,
Complementary angles are two angles that add up to 90 degrees.
Supplementary angles are two angles that add up to 180 degrees.
Now,
The ray intersects two other rays forming a right angle.
This means,
It is a complementary angle.
i.e
x + (x - 20) = 90
x + x - 20 = 90
2x = 90 + 20
2x = 110
x = 55°
Thus,
The measure of the value of x is 55°.

Find the perimeter
~~~~~~~~~~~~~~~~~~~
Answer:
P = 2x^3 + 14x^2 + 8x + 6
Step-by-step explanation:
The perimeter of this figure is P = 2W + 2L, or, in this specific case,
P = 2(7x^2 + 4x + 3) + 2(x^3), which, when expanded, comes out to:
P = 14x^2 + 8x + 6 + 2x^3, or, in standard form:
P = 2x^3 + 14x^2 + 8x + 6
