Answer:
y = (-1/2)x + 4
Step-by-step explanation:
Slope (m): (-1/2)
down one, right two
y-intercept (b): 4
y = mx + b
The slope-intercept equation if the line is [tex]y=-\frac{1}{2}x+4[/tex]
To find the slope, you must put the 2 points into the slope equation.
[tex]\frac{3-4}{2-0}=\frac{-1}{2}[/tex]
And to find the y-intercept, you must find where the line crosses the y-axis.

Y=8 when x=20 find y when x= 30
Answer:
y=13
Step-by-step explanation:
if x=20 when y=8 (we can creat equation )
x=2y+4 (you can prove that the equation is correct by substitute )
so the question is if x=30 find the value of y
30=2y+4
30‒4=2y
26=2y
26/2=2y/2
13=y

A father receives a postcard from his son who is
away at college. It simply reads
SEND
MORE
MONEY
The father is slightly upset that this is all his son
wrote but noticed something interesting. If each
letter is replaced with a single and unique digit, it
would make a true addition statement. The father
replies that he would send money if his son could
figure out what digit each letter would represent.
Answer:
S = 9, E = 5, N = 6, D = 7, M = 1, O = 0, R = 8, Y = 2
Step-by-step explanation:
The given letters are;
SEND
MORE
MONEY
If we are to add the first two words to get the third word, then we have;
SEND + MORE = MONEY
Where, the letters are unique digits
The maximum value of M = 1, because, the two words are in thousands and their sum is in tens of thousands, they can make up to only a 10
Therefore, S = 9
O = 0
D + E = 10 + Y
1 + N + R = 10 + E
1 + E = N
∴ 1 + N + R = 10 + E gives;
1 + 1 + E + R = 10 + E
R = 10 + E - (1 + 1 + E) = 8
R = 8
We have;
9 XXX + 108X = 10XXX
From 1 + N + R = 10 + E, we have;
1 + N + 8 = 10 + E
END + RE = NEY
E(1 + E)D + 8E = (1 + E)EY
(1 + E)EY - E(1 + E)D = 8E
10 + Y - D = E
By trial and error, we have;
If Y = 2 and D = 3, we have E = 9 which is not unique
Y = 4 and D = 3, we have E = 11 which is a double digit
Y = 2 and D = 7, we have E = 5
∴ N = 6 which is unique
Trying the combination gives;
S = 9, E = 5, N = 6, D = 7, M = 1, O = 0, R = 8, Y = 2
SEND + MORE = MONEY → 9567 + 1085 = 10652 which is correct.
1. What is the surface area of this rectangular prism?
A. 16 square units
B. 32 square units
C. 48 square units
D. 64 square units
Answer:
I believe it is 64 ( I might be wrong)
Step-by-step explanation:
ok so in the picture, the top of the rectangle has 8 square units so that means that the base also has 8 square units and if you look at the sides they also have 8 square unit so:
8 x 4 = 32
and then in the picture, the face of the rectangle has 16 square units so the other face also has 16 square units so:
16 x 2 = 32 plus the 32 from the sides in 64
hope that helps : )

Construct the line perpendicular to segment TU at point V
Answer:
Option (2)
Step-by-step explanation:
Steps to draw a perpendicular at a point lying on a segment;
1). Take a point on the segment at which the perpendicular is to be drawn.
2). Draw an arc from the point chosen on the segment which intersects the segment at the two different points.
3). Now mark two arcs from these points with the same radius intersecting each other on the same side of the segment.
4). Join the point of intersection of the arc with the point given on the line with straightedge.
Hence a perpendicular is drawn at a point of a segment.
These steps have been followed in option (2).
Option (2) will be the answer.
Given h(x) = 5x - 3. Find h(a + 1).
Given h(x}
Answer:
5a + 2
Step-by-step explanation:
To find h(a + 1), substitute x = a + 1 into h(x), that is
h(a + 1) = 5(a + 1) - 3
= 5a + 5 - 3
= 5a + 2
How are pairs of alternate interior angles related to one another? How are pairs of alternate exterior angles related to one another? Describe the relationship between these pairs using geometric terms.
Answer:
Each pair of alternate interior angles is congruent, and each pair of alternate exterior angles is congruent.
Step-by-step explanation:
Pairs of alternate interior angles are congruent angles located inside two lines when a transversal intersects them. Similarly, pairs of alternate exterior angles are congruent angles located outside the two lines when a transversal intersects them.
Relationships between pairs of alternate interior angles and pairs of alternate exterior anglesThe relationships are:
Pairs of Alternate Interior Angles:Location: Inside the two lines.
Formation: Formed when a transversal intersects the two lines.
Relationship: Alternate interior angles are congruent, meaning they have the same measure.
Pairs of Alternate Exterior Angles:Location: Outside the two lines.
Formation: Formed when a transversal intersects the two lines.
Relationship: Alternate exterior angles are congruent, meaning they have the same measure.
In both cases, the congruence of these angle pairs is a result of the intersecting lines and the transversal creating specific geometric relationships.Learn more on alternate angles here https://brainly.com/question/26167358

Max and his brother exercise together. Max does half as many sit-ups as his brother does during a workout. If Max's brother does between 100 and 150 sit-ups, which expression describes s, the number of sit-ups that Max does?
A. 0 ≤ s ≤ 50
B. 50 ≤ s≤ 75
C. 100 ≤ s ≤ 150
D. 200 ≤ s ≤ 300
Answer:C is the correct answer,
Step-by-step explanation:
50 ≤ s≤ 75 describes the number of sit-ups that Max does so option (B) will be correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Max does "s" number of sit-ups then max brother will do "2s".
Now,
Given that,
Max's brother does between 100 and 150 sit-ups
So,
100 ≤ 2s ≤ 150
Divide by 2 into both sides
50 ≤ s ≤ 75
Hence " 50 ≤ s≤ 75 describes the number of sit-ups that Max does".

A recipe for 1 batch of cookies calls for 1/3 cup of oil. You have 3/4 cup of oil. Do you have enough oil for 2 batches of cookies? She walks 1/2 mile from her home to the bus stop. She then travels 2 miles on the city bus. In miles, how far does the bus drop her off from school?
Answer:
a) Yes she has enough oil for 2 batches
b) 1/4 miles
Step-by-step explanation:
a) A recipe for 1 batch of cookies calls for 1/3 cup of oil. You have 3/4 cup of oil. Do you have enough oil for 2 batches of cookies?
1 batch of cookies = 1/3 cup of oil
2 batches = x
Cross Multiply
x = 2 × 1/3 cup of oil
x = 2/3 cup of oil will be needed for 2 batches
Subtracting 2/3 for 3/4
= 3/4 - 2/3
= 1/12 cup of oil is left
Yes she has enough oli for 2 batches

Lydia is having a party on Saturday. She decides to write a riddle on her invitations to describe her house number on Cypress Street. Use the clues below to find Lydia's address. My address is a 5−digit number. The tens digit is 6 less than 7. The thousands digit is twice the digit in the tens place. The hundreds digit is the greatest even number that is less than 10. The ones digit is the product of 5 and 1. The ten thousands digit is the difference between the hundreds digit and the ones digit. Lydia's address is Cypress Street.
Answer:
Lydia's address is Cypress Street is: 51823
Step-by-step explanation:
Represent the digit as ABCDE such that:
A = Ones
B = Tens
C = Hundred
D = Thousand
E = Ten Thousand
Analyzing the statements one after the other:
The tens digit is 6 less than 7.
[tex]B = 7 - 6[/tex]
[tex]B = 1[/tex]
The thousands digit is twice the digit in the tens place.
[tex]D = 2B[/tex]
[tex]D = 2 * 1[/tex]
[tex]D = 2[/tex]
The hundreds digit is the greatest even number that is less than 10.
[tex]C = 8[/tex]
The ones digit is the product of 5 and 1.
[tex]A = 5 * 1[/tex]
[tex]A = 5[/tex]
The ten thousands digit is the difference between the hundreds digit and the ones digit.
[tex]E = C - A[/tex]
[tex]E = 8 - 5[/tex]
[tex]E = 3[/tex]
Lydia's address is Cypress Street is: 51823

Answer:

y=148
x=6
Step-by-step explanation:
z+73+75=180
Combine like terms
z+148=180
Subtract 148 on both sides
z=32
z and y are angles on a line
y+32=180
subtract 32 on both sides
y=148
x+148+26=180
combine like terms
x+174=180
subtract 174 on both sides
x=6
