Step-by-step explanation:
step 1. the x intercept is when y=0.
step 2. 2x -5(0) = 20 or x = 10.
step 3. the x intercept is (10, 0)
step 4. the y intercept is when x=0.
step 5. 2(0) - 5y = 20 or y = -4
step 6. the y intercept is (0, -4).
X is less than or equal to 4
Answer:
4.4 kg
Step-by-step explanation:
Given;
Total mass of apple and pear sold = 6.9kg
Mass of apple sold = 2.5 kg
Mass of pear sold = p
The total mass of apple and pear sold is the sum of the mass of apple and mass of pear sold.
Total mass = mass of apple + mass of pear
Mass of pear = total mass - mass of apple sold
Substituting the given values;
Mass of pear p = 6.9 kg - 2.5kg = 4.4kg
Answer:
Scale factor = 1.5
Step-by-step explanation:
Formula for the scale factor,
Scale factor =
In this question, image is triangle Y and preimage is triangle X.
Scale factor of X to Y =
= 1.5
Therefore, scale factor = 1.5 is the answer.
Answer:
Step-by-step explanation:
The given equation of a parabola is,
When we compare this equation with the vertex form of the quadratic equation,
y = a(x - h)² + k
where (h, k) is the vertex,
Vertex of the parabola,
(-3, 4)
y-intercept,
