Write the equation of a line that passes through the point (1,4) and has a slope of 9.
Answers
Answer:
y=9x-5
Step-by-step explanation:
You want to find the equation for a line that passes through the point (1,4) and has a slope of 9.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 9. So you can right away fill in the equation for a line somewhat to read:
y=9x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(1,4). When x of the line is 1, y of the line must be 4.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: b is what we want, the 9 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the point (1,4).
So, why not plug in for x the number 1 and y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.
(1,4). y=mx+b or 4=9 × 1+b, or solving for b: b=4-(9)(1). b=-5.The equation of the line that passes through the point (1,4) with a slope of 9
is
y=9x-5

On Saturday a roadside vegetable stand sold 5 pumpkins and 20 watermelons and made $135.
on Sunday the roadside vegetable stand sold 10 pumpkins and 16 watermelons and made $150.
what is the cost of the pumpkins and what is the cost of the watermelons ?
Answers
Answer:
Pumkins $7 and Watermelons $5
Step-by-step explanation:
let pumkins be P and watermelons be W s0
5P+20W=135 and 10P+16W=150
express first equation in terms of P
5P+20W=135
5P=135-20W (divide equation by 5)
P=27-4W
now express the second equation using the new P value
10P+16W=150
10(27-4W)+16W=150
270-40W+16W=150
120=24W
W=5
now plug in w value and solve for p
5P+20(5)=135
P=7

JK, KL and LJ are all tangent to O (not drawn to scale). JA = 13, AL = 9, and
CK = 11. Find the perimeter of JKL.
a.)66
b.)44
c.)33
d.)48
Answers
Answer:
a.) 66
Step-by-step explanation:
Perimeter of JKL = JA + AL + CK + CL + KB + JB
JA = 13,
AL = 9,
CK = 11
CL = AL = 9 (tangents drawn from an external point are congruent)
KB = CK = 11 (tangents drawn from an external point are congruent)
JB = JA = 13 (tangents drawn from an external point are congruent)
Plug in the values
Perimeter of JKL = 13 + 9 + 11 + 9 + 11 + 13
= 66

What are the two whole numbers whose product is 294 and whose quotient is 6?
Answers
Answer: 7 and 42.
Step-by-step explanation:
Let the two whole numbers be x and y.
From the question given, we can form an equation as:
x × y = 294 ........ i
x/y = 6 .......... ii
From equation ii
x/y = 6
x = 6y
Put the value of x back into equation i
x × y = 294
6y × y = 294
6y² = 294
y² = 294/6
y² = 49
y = ✓49
y = 7
Since x × y = 294 and y = 7,
x = 294/7
x = 42
The numbers are 7 and 42.

Step-by-step explanation:
l = 5w - 4, so P = 88, then 2l + 2w = 88, so 2(5w - 4) + 2w = 88
10w - 8 + 2w = 88, so 12w = 96, so w = 8

Answers
Answer:
Step-by-step explanation:
By the property,
"Measure of the intercepted arc is double of the inscribed angle"
m(arc BC) = 2×48°
= 96°
By using the same property,
m(arc AC) = 2 × m(∠B)
m(∠B) = [tex]\frac{110}{2}[/tex]
= 55°
m(∠A) + m(∠B) + m(∠C) = 180° [Triangle sum theorem]
48° + 55° + m(∠C) = 180°
m(∠C) = 180° - 103°
= 77°
m(arc AB) = 2 × (m∠C)
= 2×77
= 154°

A telephone service representative believes that the proportion of customers completely satisfied with their local telephone service is different between the Midwest and the Northeast. The representative's belief is based on the results of a survey. The survey included a random sample of 1400 midwestern residents and 1320 northeastern residents. 50% of the midwestern residents and 38% of the northeastern residents reported that they were completely satisfied with their local telephone service. Find the 98% confidence interval for the difference in two proportions. Step 1 of 3 : Find the critical value that should be used in constructing the confidence interval.
Answers
Answer:
(0.1361 ; 0.2239)
Step-by-step explanation:
n1 = 1400 ; p1 = 0.50 ; n2 = 1320 ; p2 = 0.38
Confidence interval = mean ± margin of error
Mean = p1 - p2
Point estimate :
p1 - p2 = 0.50 - 0.38 = 0.18
Margin of Error (MOE) = Zcritical * S. E
Standard Error(S. E) :
Sqrt[(p1(1-p1)/n1) + (p2(1-p2)/n2)]
(p1(1-p1)/n1) = 0.50(0.50) / 1400 = 0.0001785
(p2(1-p2)/n2) = 0.38(0.62) / 1320 = 0.0001784
S. E = sqrt(0.0001785 + 0.0001784)
S. E = sqrt(0.0003569)
S. E = 0.0188917
Zcritical at 98% = 2.326
MOE = Zcritical * S. E
MOE = 2.326 * 0.0188917
MOE = 0.0439420942
MOE = 0.0439
Confidence interval = mean ± margin of error
Confidence interval = 0.18 ± 0.0439
Lower boundary = (0.18 - 0.0439) = 0.1361
Upper boundary = (0.18 + 0.0439) = 0.2239
(0.1361 ; 0.2239)
