Solve (x – 3)^2 = 49. Select the values of x.
–46
-4
10
52
Answer:
10
Step-by-step explanation:
The solutions for the equation (x - 3)² = 49 are x = 10 and x = -4.
To solve the equation (x - 3)² = 49, we can take the square root of both sides of the equation to eliminate the squared term.
√[(x - 3)²] = √49
Taking the square root of a square cancels out the exponent, resulting in:
|x - 3| = 7
Now, we have two cases to consider:
x - 3 = 7
In this case, we add 3 to both sides:
x = 7 + 3
x = 10
-(x - 3) = 7
Here, we distribute the negative sign:
-x + 3 = 7
Then, subtract 3 from both sides:
-x = 7 - 3
-x = 4
To isolate x, multiply both sides by -1, remembering to flip the inequality:
x = -4
Therefore, the solutions for the equation (x - 3)² = 49 are x = 10 and x = -4.

There are 90 calories in a 3/4 cup serving of cereal.
How many calories are in 1 cup?
How many calories are in 6 cups?
90
3/4
=1
=6
Answer:
120 calories in 1 cup, 720 in 6 cups
Step-by-step explanation:
I divided 90 by 3 to get 1/4 cup and then multiplied it by 4 to get for one cup. From there I multiplied by 6
Answer:
1 cup=120 calories 6 cups=720 calories
Step-by-step explanation:
We know that there are 90 calories in 3/4 of a cup and we can figure out that 30 calories are in each 1/4 of a cup because 90 divided by 3 equals 30 then just add 30 calories to 90 and get 120. Finally just do 120 times 6 and get 720 .

Answer:
The mistake he made was not distributing the 1/4 to all the terms in the parentheses. It should've instead become 1/4x + 3, which would then lead to a different answer
Answer:
He forgot to divide 12 by 4.
Step-by-step explanation:
1/4(x + 12) = 2
1/4(x) + 1/4(12) = 2
x/4 + 12/4 = 2
x/4 + 3 = 2
x/4 = -1
x = -1/4
Solve for [x]. The pair of polygons are similar. The scale factor from A to B is 9:10
Answer:
9
Step-by-step explanation:
if scale factor is 3/5, then
(x+12):35=3:5, ⇒
The value of x in the pair of polygons is 19 .
Given,
Two similar triangle .
Now,
The side of one triangle is 3x -12 .
The side of other triangle is 50 .
As the triangle are similar then the ratio of corresponding sides will be equal to the scale factor .
So,
3x - 12/ 50 = 9/10
3x - 12 = 45
3x = 57
x = 19
Thus the value of x is 19 .

Only Question #5!
If JKLM is a rectangle, find
Measure NML
Answer;
5. 22°
6. 74°
Step-by-step explanation:
5. Since rectangle JKLM has two equal diagonals that intersect each other, therefore JN = MN.
If JN = MN therefore:
m<NMJ = m<NJM
Thus:
3x + 38 = 7x - 2
Solve for x. Collect like terms
3x - 7x = -38 - 2
-4x = - 40
Divide both sides by -4
x = 10
✔️Find m<NMJ
m<NMJ = 7x - 2
Plug in the value of x
m<NMJ = 7(10) - 2 = 70 - 2
m<NMJ = 68°
✔️Find m<NML;
m<NML = 90 - 68° (Complimentary angles)
m<NML = 22°
6. Diagonal of a rhombus bisects teach vertex angle, this means that <U is divided into two equal parts. Therefore:
10x - 23 = 3x + 19
Solve for x. Collect like terms
10x - 3x = 23 + 19
7x = 42
Divide both sides by 7
x = 6
✔️Find m<RST:
m<SUT = m<RST (opposite angles of a rhombus are congruent)
Thus,
m<SUT = (10x - 23) + (3x + 19)
Plug in the value of x
m<SUT = (10(6) - 23) + (3(6) + 19)
= (60 - 23) + (18 + 19)
= 37 + 37
m<SUT = 74°
Also, m<RST = 74°

Draw the straight line y = 2x - 3
Answer:
See the picture down below
Step-by-step explanation:
When you are drawing a line you should first mark the y-intercept, which in this case it's (0,-3) because the the b in the equation is -3. Then we will go 2 units up then 1 unit right. Keep going until you've run out of room. Then draw the line going through all the points.
The graph of y = 2x - 3 is attached and slope of the given graph is 2.
What is Straight Line?A line is an infinitely long object with no width, depth, or curvature.
y=mx+b is the standard form of a line, where m is slope and b is the y intercept.
When a line passes through (x₁, y₁) and (x₂, y₂) then slope
m=y₂-y₁/x₂-x₁
The given equation is y = 2x - 3
When we compare this with standard form
m is 2 which is slope.
To draw graph we have to find few values of x and y.
If x=0,
then y=-3
(0, -3) is one point in the line.
If x=1
then y=-1
(1, -1) is second point in the line.
if x=2
y=1
if x=3
then y=3
if x=4
then y=5
Hence, the graph of y = 2x - 3 is attached and slope of the given graph is 2.
