Step-by-step explanation:
Let's turn that into a linear system:
\{ {{y=0.05x+20} \atop {y=0.25x+10}} .{y=0.25x+10y=0.05x+20.
Set the equations equal to each other and solve:
0.05x+20=0.25x+100.05x+20=0.25x+10
0.2x=100.2x=10
x=50x=50
We then plug in to get yy :
0.25(50)+10=22.50.25(50)+10=22.5
The solution to the system is \{ {{x=50} \atop {y=22.5}} .{y=22.5x=50. .
Now, let's turn our attention to the statements.
The first one is false: Emilia's rate is higher, and the two plans cost the same at 50 texts, after which point Hiroto's plan becomes cheaper!
The second one is also false: we already figured out that the lines intersect at x=50x=50 .
The third statement is also false: as above, the lines intersect at x=50x=50 .
The fourth statement is true: the lines intersect at x=50x=50 .
In conclusion, the fourth statement - "Both plans cost the same when 50 texts are sent" - is true.

Petra jogs 4 miles in 36 minutes. At this rate, how long would it take her to jog 10 miles.
Write: x^2 + 8x + 10 in the form (x + a)^2 + b
Answer:
Step-by-step explanation:
Here, b=8 and c=10, so,
a=b/2
=8/2
=4
and
b=c-a²
=10-16
=-6
∴(x+a)²+b=(x+4)²-6

Ok the mistake yall were doing was adding 9,600 with 53,000 when they were asking for the commission so basically plus it says "what is his commission this year?"

Answer:
a
Step-by-step explanation:
Solving the inequality
[tex]\frac{x+3}{6}[/tex] > [tex]\frac{x}{4}[/tex] + 1
Multiply through by 12 ( the LCM of 6 and 4 ) to clear the fractions
2(x + 3) > 3x + 12
2x + 6 > 3x + 12 ( subtract 2x from both sides )
6 > x + 12 ( subtract 12 from both sides )
- 6 > x , that is
x < - 6
The only value less than - 6 is - 10
Thus x = - 10 is a solution to the inequality
Haley has not been able to maintain the $1,200 minimum balance required to avoid
fees on her checking account. She wants to switch to a different account with a fee
of $0.25 per check and a $10.50 monthly maintenance fee. Haley wants to estimate
the fees for her new account. To the right is a summary of the checks she has written
from May to August.
Answer:
MAy to August is 3 months.So 10x3 is 30.However,theres still the cents.So 50x3 is 150.So you have one more dollar,and 50 cents.30+1 is 31.So your answer is $31.50.Ill be glad to help again

In baseball, two statistics, the ERA (Earned Run Average) and the WHIP (Walks and Hits per Inning Pitched), are used to measure the quality of pitchers. For both measures, smaller values indicate higher quality. The following computer output gives the results from predicting ERA by using WHIP in a least-squares regression for the 2017 baseball season.
Variable DF Estimate SE T
Intercept 1 −5.0 0.26 −19.3
WHIP 1 6.8 0.14 47.4
Which of the following statements is the best interpretation of the value 6.8 shown in the output?
a. ERA is predicted to increase by 6.8 units for each 1 unit increase of WHIP.
b. WHIP is predicted to increase by 6.8 units for each 1 unit increase of ERA.
c. For a pitcher with 0 units of WHIP, the ERA is predicted to be approximately 6.8 units.
d. For a pitcher with 0 units of ERA, the WHIP is predicted to be approximately 6.8 units.
e. Approximately 6.8% of the variability in ERA is due to its linear relationship with WHIP.

D. (12,0)
Answer:
answer is c (plato users)

The answer is option C (4,0)
What is a straight line graph?The graph follows a straight line equation shows a straight line graph.equation of a straight line is y=mx+cy represents vertical line y-axis.x represents the horizontal line x-axis. m is the slope of the line
slope(m)=tan∅=y axis/x axis.
c represents y-intercepts (it is the point at which the line cuts on the y-axis)Straight line graphs show a linear relationship between the x and y values.
solving the equation:-
⇒y = (x − 5)(x2 − 7x + 12)
⇒y= 2x²-7x²+12x-10x+35x-60
⇒y=-5x²+37x-60
